2025 Form 1 Instructions 3 Major 2025 Tax Law Changes For more up-to-date and detailed information and to view all of the public written statements refer­ enced in these instructions, visit mass.gov/dor. Filing Due Dates Form 1 is due on or before April 15, 2026. 4% Surtax Starting with tax year 2023, personal income tax­ payers must pay an additional 4% on taxable in­ come over $1,000,000, increased annually for inflation. For the 2025 tax year, the threshold is $1,083,150. Employer-Provided Parking, Transit Pass, and Commuter Highway Vehicle Benefits Exclusion Amounts Massachusetts conforms to the federal income exclusion for employer-provided parking, tran­ sit pass, and commuter highway vehicle trans­ portation benefits. The IRS has determined that the 2025 inflation-adjusted monthly exclusion amounts are $325 for employer-provided park­ ing and $325 for combined transit pass and com­ muter highway vehicle transportation benefits. Penalty for Failure to Obtain Health Insurance Massachusetts requires most adults 18 and over with access to affordable health insurance to ob­ tain it. In 2025, individuals must be enrolled in health insurance policies that meet minimum creditable coverage standards defined in regula­ tions adopted by the Commonwealth Health In­ surance Connector Authority (Health Connector). Individuals who are deemed able to afford health insurance but fail to obtain it are generally subject to penalties in Massachusetts for each month of noncompliance in the tax year. The monthly pen­ alties for 2025, which will be imposed through the individual’s personal income tax return, are set out in Technical Information Release (TIR) 25-1 and are based on the monthly insurance premium for which an individual would have qualified through the Health Connector. Withholding on Sales of Massachusetts Real Estate Sales of Massachusetts real estate are subject to withholding on the gross sales price or estimated net gain from the sale, when the gross sales price equals or exceeds $1,000,000. The amount with­ held is calculated based on the gross sales price of the real estate, unless the seller elects the alter­ native withholding calculation based on the sell­ er’s estimated net gain from the sale of the real estate. The seller must report gain from the sale of real estate on their return for the tax year in which the sale takes place, and the seller may claim the amount withheld as a credit on their return. The credit is available for tax years beginning on or after January 1, 2025, for real estate closings that occur on or after November 1, 2025. There are many exemptions from the withholding require­ ment, including for sales by residents, but there are reporting requirements applicable to all sellers. For additional information see 830 CMR 62B.2.4 and the Department’s website at mass.gov/dor. Circuit Breaker Tax Credit Taxpayers aged 65 or older who own or rent res­ idential property located in Massachusetts are al­ lowed a credit equal to the amount by which their total real estate tax payments, or 25% of their rent in the case of a renter, exceeds 10% of the tax­ payer’s total income. The credit cannot exceed a certain maximum amount that is determined by multiplying a statutory base amount by a cost-of- living adjustment for the calendar year in which the taxable year begins. The maximum credit for tax year 2025 is $2,820. The amount of the credit is subject to limitations based on the taxpayer’s total income and the as­ sessed value of the real estate, which for tax year 2025 must not exceed $1,298,000. For purposes of calculating the credit, total income and maxi­ mum credit thresholds are adjusted annually for inflation. For tax year 2025, an eligible taxpayer’s total income cannot exceed $75,000 in the case of a single filer who is not a head of household filer; $94,000 in the case of a head of household filer; and $112,000 in the case of a joint filer. To qualify for the credit, a taxpayer must be age 65 or older and must occupy the property as his or her principal residence. Massachusetts Credits Several new credits are available. In addition, cer­ tain existing credits have been revised. These are discussed in detail in TIR 24-16 and TIR 25-5. New Climatetech Tax Incentive Program The Climatetech Tax incentive program adds three new credits for eligible expenses incurred by cli­ matetech companies in developing and deploying technologies aimed at mitigating or adapting to cli­ mate change. The credit takes effect for tax years beginning on or after January 1, 2024. A clima­ tetech company must be certified as such by the Massachusetts clean energy technology center (“MassCEC”). The credits include the following. • The Climatetech Incentive Jobs Credit is awarded in an amount determined by MassCEC (in consultation with the Department of Revenue) to climatetech companies that create at least five new jobs in the climatetech sector. The credit is available to both corporate excise and personal income tax filers. • The Climatetech Capital Investment Credit is awarded in an amount, determined by MassCEC, up to fifty percent of a climatetech company’s in­ vestment in a climatetech facility. The credit is available to both corporate excise and personal income tax filers. • The Climatetech Qualified Research Expenses Credit is awarded at the discretion of MassCEC in an amount equal to the sum of (i)10% of the excess of qualified research expenses for the tax­ able year, over a base amount, and (ii)15% of the basic research payments as determined for federal tax purposes. The credit is available to corporate excise filers only. See TIR 25-5, Section I, for a more detailed dis­ cussion of the credits, including eligibility, refund­ ability, carryover of unused credits, and limitations on the credits. New Live Theater Credit The Live Theater Credit is available for costs in­ curred in presenting certain live theater produc­ tions in Massachusetts. The credit is equal to the sum of (i) 35% of a theater company’s total in- state payroll costs, (ii) 25% of its total in-state production and performance expenditures, and (iii) 25% of its total in-state transportation ex­ penses. The Massachusetts Office of Business Development awards the credit based on applica­ tions submitted by theater companies. The credit is available to both corporate excise and personal income tax filers. The credit is transferable but is not refundable. Unused credit may be carried for­ ward for five years. The credit is available for tax years beginning on or after January 1, 2025, and will expire on January 1, 2030. For additional in­ formation see TIR 25-5, Section II. New Homeownership Credit The Homeownership Credit is available to real estate developers that build certain new housing units. The credit is awarded in an amount deter­ mined by the Massachusetts Housing Finance Agency based on applications submitted by de­ velopers. The credit is available to both corporate excise and personal income tax filers. The credit is transferable but not refundable. The credit is avail­ able for tax years beginning on or after January 1, 2025. For additional information, including eligibil­ ity rules, see TIR 24-16, Section II. New Qualified Conversion Credit The Qualified Conversion Credit is available to real estate developers that convert existing commer­ cial property to residential or mixed use. The credit is awarded in an amount determined by the Exec­ utive Office of Housing and Livable Communities based on applications submitted by developers. The credit cannot exceed 10% of a developer’s costs. The credit is available to both corporate ex­ cise and personal income tax filers. The credit is transferable but not refundable. The credit is avail­

2025 Form 1 Instructions 4 able for tax years beginning on or after January 1, 2025, and expires on December 31, 2029. For additional information see TIR 24-16, Section III. Other Credits Certain existing credits have been revised by re­ cent legislation. These revisions expand the avail­ ability of the following credits for the tax years indicated: • Community Investment Credit (effective for tax years beginning on or after January 1, 2025); • Economic Development Incentive Program Credit, (effective for credits awarded on or after November 20, 2024); • Historic Rehabilitation Credit, (effective for tax years beginning on or after January 1, 2024); • Life Sciences Tax Incentive Program (effec­ tive for tax years beginning on or after January 1, 2024); • Research Credit (effective for research ex­ penses incurred on or after November 20, 2024); • Offshore Wind Investment Tax Credit (effective retroactively for tax years beginning on or after January 1, 2023); and • Offshore Wind Jobs Tax Credit (effective retro­ actively for tax years beginning on or after Janu­ ary 1, 2023). For additional information see TIR 24-16 Sections IV and V and TIR 25-5 Sections V through VIII and X through XIII. Singles Sales Factor Apportionment Effective for tax years beginning on or after Jan­ uary 1, 2025, personal income tax filers that are required to apportion their income to Massachu­ setts must do so by using the sales factor only. See TIR 24-4, Section IV, for a general discussion of this change. Federal Conformity In general, a taxpayer’s Massachusetts gross in­ come and many deductions are based on the taxpayer’s federal gross income and deductions under the Internal Revenue Code (IRC) as of a spe­ cific date. For tax years beginning on or after Jan­ uary 1, 2024, the Massachusetts personal income tax generally conforms to the IRC as amended and in effect on January 1, 2024. For further in­ formation regarding federal tax law changes see TIR 24-14, TIR 26-4: Massachusetts Conformity to Certain Provisions in Public Law No. 119-21, and TIR 26-xx: Tax Provisions in the Fiscal Year 2026 Final Mid-Year Supplemental Appropriation Bill for a discussion of Massachusetts’ conformity to recent federal legislation. As a general rule, Massachusetts does not con­ form to personal income tax law changes to the IRC made after January 1, 2024. However, certain specific Massachusetts personal income tax pro­ visions, as set forth in MGL ch. 62, § 1(c), auto­ matically conform to the IRC currently in effect. The provisions of the IRC that Massachusetts con­ forms to on a current basis include those provi­ sions relating to: • Roth IRAs; • IRAs; • The exclusion for gain on the sale of a principal residence; • Trade or business expenses; • Travel expenses; • Meals and entertainment expenses; • The maximum deferral amount of government employees’ deferred compensation plans; • The deduction for health insurance costs of self-employed taxpayers; • Medical and dental expenses; • Annuities; • Health savings accounts; • Employer-provided health insurance coverage; • Amounts received by an employee under a health and accident plan; and • Contributions to qualified tuition programs. Federal Tax Law Changes (***) Federal legislation passed in 2025 made a num­ ber of changes to the IRC. The Massachusetts per­ sonal income tax adopts only those changes that relate to provisions that Massachusetts adopts on a current basis (as listed above). Relief from Certain Penalties and Interest on Late Payments and Underpayments (***) Taxpayers who timely filed their tax year 2025 re­ turn or timely made their 2025 extension payment applying certain provisions of federal Public Law No. 119-21 before the enactment of the Supple­ mental Budget can obtain relief from certain pen­ alties and interest. No interest or penalties shall be imposed on any underpayments, late payments, or underpaid estimated payments attributable to changes in law made by the Supplemental Budget for those taxpayers. See St. 2026, c. 101, § 38. This relief applies to adjustments taxpayers are re­ quired to make to their deductions under IRC §§ 163(j)(8), 168(n), 174, 174A, and 179, and any exclusions taken under IRC § 1400Z-2. See the "Filing an Amended Re turn" section. (***) Business Interest Expense Deduction (***) Starting with tax year 2025, federal law has been revised to increase the limitation on the deduction for business interest expenses. See IRC § 163(j). IRC § 163(j) limits the business interest expense deduction to a percentage of a taxpayer’s adjusted taxable income. See TIR 19-17. The federal com­ putation of adjusted taxable income has been revised to exclude certain income, reducing the amount of the limitation and thereby increasing the potential deduction. Federal law has changed the definition of adjusted taxable income in IRC § 163(j) in several respects. Massachusetts does not adopt the change to the federal adjusted taxable income definition in IRC § 163(j)(8) for tax years 2025 and 2026 that perma­ nently allows the calculation to be made without regard to any deduction allowable for depreciation, amortization, or depletion. See TIR 26-4: Massa­ chusetts Conformity to Certain Provisions in Pub­ lic Law No. 119-21 and TIR 26-xx: Tax Provisions in the Fiscal Year 2026 Final Mid-Year Supplemen­ tal Appropriation Bill. Special Depreciation Allowance for Qualified Production Property (***) Federal law provides a special depreciation allow­ ance for specified qualified production property placed in service after July 4, 2025, and before January 1, 2031. See IRC § 168(n). Qualified production property refers to nonresidential real property used in manufacturing, chemical or agri­ cultural production, or refining that results in the production of physical products. The federal spe­ cial depreciation allowance is 100% of the cost of such property. Massachusetts does not adopt the federal spe­ cial depreciation allowance for tax years 2025 and 2026. The amount of the federal deduction is disallowed as a Massachusetts deduction. How­ ever, taxpayers may recover the cost of qualified production property using a depreciation method available under the provisions of federal tax law that Massachusetts has adopted. See TIR 26-4: Massachusetts Conformity to Certain Provisions in Public Law No. 119-21 and TIR 26-xx: Tax Pro­ visions in the Fiscal Year 2026 Final Mid-Year Sup­ plemental Appropriation Bill. Domestic Research and Experimental Expense Deduction (***) Starting with tax year 2025, domestic research and experimental expenses are fully deductible in the tax year they are incurred pursuant to IRC § 174A for federal tax purposes. For federal tax purposes, eligible expenses that were capitalized in prior years may be deducted in full in the 2025 tax year or ratably in a two-year period in 2025 and 2026 tax years. For federal tax purposes, certain small businesses may also elect to retroactively apply IRC § 174A by amending their 2022, 2023, and 2024 federal tax returns. Massachusetts does not conform to IRC § 174A for tax year 2025 or any prior tax years. For Massa­ chusetts purposes, all research and experimental costs must be capitalized and recovered through amortization deductions pursuant to IRC § 174 as amended and in effect prior to Public Law 119-21. Previously amortized amounts may be deducted as permitted by federal amortization schedules in effect prior to the enactment of IRC § 174A. Filers that claimed the federal IRC § 174A deduction on

2025 Form 1 Instructions 5 their Massachusetts returns for prior years must file amended Massachusetts returns to reduce the amount of the Massachusetts deduction. See TIR 26-4: Massachusetts Conformity to Certain Provi­ sions in Public Law No. 119-21 and TIR 26-xx: Tax Provisions in the Fiscal Year 2026 Final Mid-Year Supplemental Appropriation Bill. See the "Filing an Amended Return" section. (***) For the most up-to-date and detailed information about penalty and interest relief for tax years 2022–2024 related to Massachusetts conformity with federal law P.L. 119-21, visit mass.gov/dor. Increased IRC § 179 Dollar Limitations (***) Starting with tax year 2025, the federal limitation on the full expense deduction under IRC § 179 has been increased to $2.5 million and the deduction phases out at $4 million. Both amounts are subject to adjustment for inflation. Massachusetts does not adopt these limits for tax years 2025 and 2026. The Massachusetts limit and phase-out amounts, adjusted for inflation, are $1,250,000 and $3,130,000. See TIR 26-4: Mas­ sachusetts Conformity to Certain Provisions in Public Law No. 119-21 and TIR 26-xx: Tax Provi­ sions in the Fiscal Year 2026 Final Mid-Year Sup­ plemental Appropriation Bill. Changes to the Tax Treatment of Investments in Qualified Opportunity Zones Under IRC § 1400Z-2 (***) Federal law permanently renewed and modified the tax benefits of investments in qualified oppor­ tunity zones provided by IRC § 1400Z-2. Massachusetts does not adopt these renewals and modifications for taxable years beginning on or after January 1, 2025, but before January 1, 2027. See TIR 26-4: Massachusetts Conformity to Certain Provisions in Public Law No. 119-21 and TIR 26-xx: Tax Provisions in the Fiscal Year 2026 Final Mid-Year Supplemental Appropriation Bill. Qualified Opportunity Zones Must be Located Entirely Within Massachusetts (***) For taxable years beginning on or after January 1, 2026, Massachusetts requires that a qualified opportunity zone must be located entirely within Massachusetts. Taxpayers must add back any ex­ clusions taken for investments made after Jan­ uary 1, 2026, in qualified opportunity zones not located entirely within Massachusetts. See TIR 26-4: Massachusetts Conformity to Certain Provi­ sions in Public Law No. 119-21 and TIR 26-xx: Tax Provisions in the Fiscal Year 2026 Final Mid-Year Supplemental Appropriation Bill. Note: Massachusetts does not adopt the federal deduction for tip income (IRC § 224) or the federal deduction for overtime pay (IRC § 225). Massa­ chusetts does not adopt the new revision for the business interest deduction (IRC § 163(j)(8)) or the federal special depreciation allowance (IRC § 168(n)). Massachusetts does not adopt the new eligible domestic research and experimental ex­ penses (IRC § 174A) or the new limits for the de­ preciation and IRC § 179 deduction (IRC § 179). For details see TIR 26-xx and the above sections. For further information regarding federal tax law changes see TIR 24-14 and Working Draft TIR: Massachusetts Conformity to Certain Provisions in Public Law No. 119-21. Applying for Relief Related to Massachusetts Conformity with the Provisions of Federal Law P.L. 119-21 (***) To claim relief from certain penalties on late pay­ ments and underpayments for the 2025 tax year for a personal income taxpayer that has a valid ex­ tension but has not yet filed a return, an individual subject to Massachusetts income tax must attach to their original 2025 tax return: (***) • Massachusetts Schedule M-2210 (Underpayment of Massachusetts Estimated Tax). • Massachusetts Schedule TDS (Taxpayer Disclosure Statement), including: • The following statement: “Taxpayer is apply- ing for relief related to Massachusetts con- formity with the provisions of federal law P.L. 119-21” and clearly specify which IRC pro- vision(s) are being adjusted. Relevant provi- sions include: • Domestic Research and Experimental Ex- pense Deductions under Code § 174 and New Code § 174A; • Special Depreciation Allowance for Qualified Production Property under Code § 168(n) • Increased Dollar Thresholds for Deductible Amounts when Expensing Certain Business Assets under Code § 179; • Modification of Limitation on Business Interest Expense Deduction under Code § 163(j); and • Changes to the Tax Treatment of Invest- ments in Qualified Opportunity Zones under Code § 1400Z-2. • An explanation of how the adjustment was calculated, and how it is reflected in the at- tached Schedule M-2210.

Privacy Act Notice Under the authority of 42 USC § 405(c)(2)(C)(i), and MGL ch 62C, § 5, DOR has the right to require an individual to furnish his or her Social Security number on a state tax return. This information is mandatory. DOR uses Social Security numbers for taxpayer identification to assist in process­ ing and keeping track of returns and in determin­ ing and collecting the proper amount of tax due. Under MGL ch 62C, § 40, the taxpayer’s identi­ fying number is required to process a refund of overpaid taxes. Although tax return information is generally confidential pursuant to MGL ch 62C, § 21, DOR may disclose return information to other taxing authorities and those entities specified in MGL ch 62C, §§ 21, 22 or 23, and as otherwise authorized by law. Filing Your Massachusetts Return If you were a resident of Massachusetts and your gross income was more than $8,000 — whether received from sources inside or outside of Massa­ chusetts — you are required to file a Massachu­ setts income tax return. If your gross income was $8,000 or less, you do not need to file a return. If you did not live in Massachusetts but received Massachusetts source income in excess of your personal exemption amount multiplied by the ratio of your Massachusetts income to your total in­ come, you must file as a nonresident on the Non­ resident/Part-Year Resident Income Tax Return, Form 1-NR/PY. If, during the taxable year, you either moved to Massachusetts or terminated your status as a Mas­ sachusetts resident to establish residency outside the state, and your gross income was more than $8,000 — whether received from sources inside or outside of Massachusetts — you must file as a part-year resident on the Form 1-NR/PY. What Is Gross Income? Massachusetts gross income includes the following: • All wages, salaries, tips, bonuses, fees and other compensation; • Taxable pensions and annuities; • Pension income from another state or political subdivision before any deduction; • Taxable IRA/Keogh and Roth IRA distributions; • Taxable alimony, see Schedule X instructions; • Income from a business, trade, profession, partnership, S corporation, trust or estate; • Rental, royalty and REMIC income; • Unemployment compensation; • Taxable interest and dividends; • Gambling winnings; • Capital gains;

2025 Form 1 Instructions 6 • Forgiveness of debt; • Mortgage forgiveness; • Taxable portion of scholarships and fellow ships; and • Any other income not specifically exempt. • Massachusetts gross income also in cludes the fol­ lowing, which are not subject to U.S. income tax: • Interest from obligations of states and their po­ litical subdivisions, other than Massachusetts and its political subdivisions; and • Income earned by a resident from foreign employment. Massachusetts gross income does not include: • Interest on obligations of the U.S. and U.S. territories; • Pension income received from a contributory annuity, pension, endowment or retirement fund of the U.S. government or the Commonwealth of Massachusetts and its political subdivisions. • Amounts received as U.S. Social Security, pub­ lic welfare assistance, Veterans Administration disability payments, G.I. Bill education payments, certain worker’s compensation, gifts, accident or life insurance payments, or certain payments re­ ceived by Holocaust survivors; and • Compensation earned by members of the armed forces for service in a combat zone (excluded to the same extent as under federal law). Am I a Resident, Nonresident, or Part-Year Resident? There are four different categories of resident sta­ tus under Massachusetts tax law: • You are a full-year resident if your residence (domicile) is in Massachusetts or if you maintain a permanent place of abode in Massachusetts and during the year spend more than 183 days, in the aggregate, in the state. If you fit this description you should file a Massachusetts Resident Income Tax Return, Form 1. • You are a nonresident if you were not a res­ ident of Massachusetts but received Massachu­ setts income (e.g., from a job in Massachusetts). You must report such income by filing a Massa­ chusetts Form 1-NR/PY. • You are a part-year resident if you either moved into or moved out of Massachusetts during the taxable year. In this case, you must reduce cer­ tain income, deductions and exemptions based on the number of days you were a resident or on the amount of your income that is subject to Massa­ chusetts tax. Part-year residents must file a Mas­ sachusetts Form 1-NR/PY. • You are both a nonresident and part-year res­ ident if you meet the criteria above for both the part-year resident and nonresident categories. If filing as a nonresident and part-year resident, the Schedule R/NR must be completed. Are Military Personnel Required to File? If you enlisted in the service as a Massachusetts resident and have not established a new domicile (residence) elsewhere (refer to military guide­ lines), and if your gross income is more than $8,000, you are required to file a Massachusetts resident income tax return. This applies even though you may be stationed outside of Massa­ chusetts. The words residence and domicile are used to denote the place where you have your permanent home and to which, whenever you are absent, you have the intention of returning. Non­ resident military personnel stationed in Massa­ chusetts may be subject to Massachusetts taxes and should file Form 1-NR/PY if they earn income from outside military sources. Military Spouses. The Military Spouses Res­ idency Relief Act (P.L. 111-97) prohibits a ser­ vice-member’s spouse from either losing or ac­ quiring a residence or domicile for purposes of taxation because of being absent or present in any U.S. tax jurisdiction solely to be with the service­ member in compliance with the servicemember’s military orders. In general, for Massachusetts tax purposes, the law affects only servicemembers and their spouses who are domiciled in a state other than Massachusetts. As of January 5, 2023, the Veterans Auto and Ed­ ucation Improvement Act (P.L. 117–333) allows a servicemember and the spouse of such service­ member to choose as their residence or domicile for each taxable year of the marriage, regardless of the date of the marriage, from any of the fol­ lowing: (a) the residence or domicile of the ser­ vicemember; (b) the residence or domicile of the spouse; or (c) the permanent duty station of the servicemember. What Are the Rules for Filing a Joint Return? A joint Form 1 is generally not allowed unless both spouses were Massachusetts residents for the same portion of 2025. If your spouse died during 2025, you may still choose to file a joint return. If you are legally married, you have the option of filing either a joint return or a married filing sep­ arate return. Married taxpayers who file a joint return are allowed to claim the following exemp­ tions, deductions and credits which married tax­ payers filing separate returns may not claim: • A credit of $440 for a Child and Family Tax Credit for a dependent member of household under age 13, a dependent who is over age 65 or disabled or the taxpayer’s spouse, who is physically or men­ tally incapable of taking care of himself or herself; • No Tax Status if joint Massachusetts AGI was $16,400 or less plus $1,000 for each dependent; • Limited Income Credit if joint Massachusetts AGI is between $16,400 and $28,700 plus $1,750 for each dependent; • Excess unused exemptions against interest income (other than interest from Massachusetts banks), dividends or capital gain income; and • A senior circuit breaker tax credit allows senior citizens meeting certain eligibility criteria to claim a refundable credit on their state income taxes for the real estate taxes paid on the Massachusetts residential property they own or rent, and which they occupy as their principal residence. The credit is the amount by which the real estate tax payment or 25% of the rent constituting real estate tax pay­ ments exceeds 10% of their total income, but not more than $2,820. The credit is refundable to the extent the credit exceeds the taxpayer’s tax liability. How Do I File a Decedent’s Return? A final income tax return must be filed for a tax­ payer who died during the taxable year. This re­ turn should include income received until date of death. It must be signed and filed by his/her per­ sonal representative, administrator or surviving spouse for the portion of the year before the tax­ payer’s death. Be sure to fill in oval 1 if the taxpayer who was listed first on last year’s income tax re­ turn is deceased, or oval 2 if the taxpayer who was listed second on last year’s income tax return is deceased. Enter the date of death for the deceased taxpayer. Also, enclose Form M-1310, Statement of Claimant to Refund Due on Behalf of Deceased Taxpayer, with the refund claimant’s name and So­ cial Security number clearly printed. A joint return may be filed by a surviving spouse. In the case of the death of both spouses, a final return must be filed by their legal representative. Any income of $100 or more received for the dece­ dent for the taxable year after the decedent’s death, and for succeeding taxable years until the estate is completed, must be reported each year on Mas­ sachusetts Form 2, Massachusetts Fiduciary In­ come Tax Return. Form 2 is available online at mass.gov/dor. If the decedent’s return shows a refund due, and if the Probate Court has not appointed a legal rep­ resentative and none is contemplated, a Massa­ chusetts Form M-1310 must be enclosed with the return so the refund check may be made payable to the proper person. Should I Make Estimated Tax Payments in 2026? Every resident or nonresident who expects to pay more than $400 in Massachusetts income tax on income which is not covered by Massachusetts withholding must pay Massachusetts estimated

Automatic Extensions All taxpayers filing personal income tax returns are automatically granted a six-month extension of time to file their tax return as long as at least 80% of the total amount of tax ultimately due on or before the due date prescribed for payment of the tax has been paid. See TIR 16-10. Also, if you are making a payment of $5,000 or more, you are required to submit your extension payment electronically. Failure to do so will result in a penalty. If you are making a payment of less than $5,000, you also have the option of filing your extension electronically. You do not need to file an extension if no payment is due. If there is a tax due with your extension, payment can be made through Electronic Funds Withdrawal. Form 1 Extension Worksheet 1. Enter amount from Form 1, line 32 . . . . . . . . . . . . . . 2.

Note: Your extension will not be valid if you fail to pay 80% of your total tax liability through withhold- ing, estimated tax payments or with your extension . Must I File on a Calendar Year Basis? No. You may file on a fiscal year basis if you keep your books and records on that fiscal year basis and if you receive permission from the Commis­ sioner of Revenue. If you file on a fiscal year basis, you must file on or before the fifteenth day of the fourth month after the end of your fiscal year. Taxpayers filing on a fiscal year basis must com­ plete and file Form 13, Notice of Designation of Fiscal Year, available at mass.gov/dor or by call­ ing (617) 887-6367 or toll-free in Massachusetts (800) 392-6089. Fiscal Year Filers Fiscal year filers should file using the tax form for the calendar year within which the short year falls. If the short year spans more than one calendar year, the filer should file using the tax form for the calendar year in which the short year began. If the current form is not available at the time the short year filer must file, the filer should follow the rules explained in TIR 11-12. What If I am Unable to Pay? If you are unable to pay the full amount of tax that you owe, you should pay as much of your tax lia­ bility as possible with this return. You will receive a bill from DOR for the remaining amount of tax due plus accrued interest and penalty charges. If the amount of that bill is less than $10,000 and you still cannot pay it in full, you must apply formally to DOR for a small payment agreement in order to avoid collection activity. You can apply for a small payment agreement by visiting Mass TaxConnect at mass.gov/masstaxconnect. Note: Do not mail your request for a payment agreement with your tax return. Requests can be made once a bill is issued through DOR’s Mass TaxConnect application at mass.gov/dor or by calling DOR at (617) 887-6367. Setting up a small payment agreement will allow you to make monthly payments within a set time period to sat­ isfy your unpaid liability. Name and Address Print the full name, address, and Social Security number of each person filing the return in the spaces provided. Enter names as they appear on your federal return. Social Security Number(s) Be sure to enter your Social Security number(s) on your return. Also, enter your Social Security number on pages 2 through 4 of Form 1 and on page 2 of Schedule B or Schedule C, if filed. Failure to show the correct Social Security number in the space provided will delay the processing of your return. If filing jointly, list your number and your spouse’s number in the order they appear on your federal return. Taxpayers filing their U.S. return using an Individual Taxpayer Identification num­ ber (ITIN) should enter that ITIN as their Social Security number in the appropriate space. Also, be sure your employer has listed the correct So­ cial Security number on your Form W-2. If you are married, you must list your spouse’s name and Social Security number even if you are filing a sep­ arate return, except as provided below. See line 1 instructions for married filing a separate return. To apply for an SSN, you must complete Form SS-5. Form SS-5 is available online at socialsecu- rity.gov, from your local Social Security Adminis- tration (SSA) office, or by calling the SSA at (800) 772-1213. It usually takes about two weeks to re- ceive an SSN. If you are a nonresident or resident alien and you do not have and are not eligible for an SSN, you must apply for an ITIN. For details on how to do so, see Form W-7 and its instructions. Form W-7 is available online at irs.gov or by calling the IRS at (800) 829-1040. It usually takes about four to six weeks to receive an ITIN. Note: You must wait until you receive an ITIN or SSN to file your Massachusetts return. Filing an Amended Return Note: When filing an Amended return, the Amended return oval must be filled in. For ex­ ample, if you are filing an Amended return due to a Federal amendment, both the Amended return oval and the Federal amendment oval must be filled in. Filing an Amended Return If you need to change a line item on your re­ turn, complete a new return with the corrected information and fill in the Amended return oval. Your amended return must include all schedules filed with the original return even if there are no changes to the schedules. Mail your amended re­ turn to the same address used for original returns. Do not file Form ABT with your amended return. An amended return can be filed to either increase or decrease your tax. An amended return should also be filed to correct a credit amount (such as withholding) or to dispute a health care penalty. Generally, an amended return must be filed within three years of the date that your original return was filed. Visit mass.gov/dor/amend for more in­ formation about filing an amended return. Federal Changes If your amended return includes changes you have reported on an amended federal return filed with the IRS for the same tax year or if you are amend­ ing due to changes as a result of a federal audit, fill in the Federal amendment oval. If your amended return does not report changes that result from the filing of a federal amended re­ turn or from a federal audit (for example, if the amended Massachusetts return is reporting a rental deduction not claimed on the original re­ turn) fill in only the Amended return oval. Other Jurisdiction Change If your amended return includes changes resulting from another state or jurisdiction audit or change, fill in the Other Jurisdiction change oval and enter date of change in the space provided. Amended Return Due to IRS BBA Partnership Audit If your amended return includes changes made due to an IRS BBA Audit, fill in the Amended re­ turn due to IRS BBA Partnership Audit oval.

For more up-to-date and detailed information concerning penalty and interest relief related to Massachusetts’ conformity with the provisions of federal law P.L. 119-21, visit mass.gov/dor. Consent to Extend the Time to Act on an Amended Return treated as Abatement Application In certain instances, an amended return show­ ing a reduction of tax may be treated by DOR as an abatement application. Under such circum­ stances, by filing an amended return, you are giv­ ing your consent for the Commissioner of Reve­ nue to act upon the abatement application after six months from the date of filing. See TIR 16-11. You may withdraw such consent at any time by con­ tacting the DOR in writing. If consent is withdrawn, any requested reduction in tax will be deemed de­ nied either at the expiration of six months from the date of filing or the date consent is withdrawn, whichever is later. Filing an Application for Abatement File an Application for Abatement only to dispute one of the following: • Penalties • Audit assessments • Responsible person determinations For the fastest response time, file your dispute on­ line at mass.gov/masstaxconnect. If you cannot file online, use Form ABT. Visit mass.gov/dor/amend for additional informa­ tion about filing an amended return, or filing an application for abatement. Form 1 Frequent Errors Not entering the information below correctly may result in an item being adjusted or removed. • Name Enter your name as shown on your gov­ ernment-issued ID with the first, last and middle in the designated fields for each type. • Line 2c You must fill in the bubble for each spouse over 65 and enter a “1” or “2” in the Total box accordingly. • Line 3 If you are a Massachusetts state, city, town, or county employee, you must report the State wages, tips etc. amount from box 16 of Form W-2. • Line 14 Enter the total qualified rent paid in 2025 in the box, then divide by 2. • Line 38 You must submit all documents that have Massachusetts withholding, including pass- through entity or K-1 withholding. You must also include Schedule 62-WH. • Lines 39 and 40 Be sure to differentiate any overpayment from 2024 as a credit carry forward on line 39 and do not list it as 2025 estimated tax payment on line 40. • Line 44 Schedule CB must be completed and submitted with your return. • Line 49 Excess Paid Family Leave withholding (PFML) is not the amount shown on your Form W-2. You must use the worksheet for line 49 to see if you qualify and to calculate the excess amount. Each taxpayer would need to have multiple W-2’s and to have paid PFML greater than $810.06 to qualify. Or, have paid on the gross amount of self-employment income, not the net. • Schedules B, C, D Entries should be positive values unless there is a box to mark to indicate a negative value. • Schedule HC You must complete and submit Schedule HC showing the subscriber number, member ID or group number from insurance card. Form 1095 is a federal form and cannot be used to report health care coverage in Massachusetts. Voluntary Contribution to State Election Campaign Fund You, and your spouse if filing jointly, may volun­ tarily contribute $1 each to the State Election Cam­ paign Fund. The purpose of this fund is to provide limited public financing for campaigns of eligible candidates for statewide and elective office. This contribution will not change your tax or reduce your refund. Veterans Benefits Fill in the appropriate oval(s) for you, and/or your spouse if married filing a joint return, if you are a veteran who served in the Armed Forces of the United States in active service as part of Operation Enduring Freedom, Operation Iraqi Freedom, Op­ eration Noble Eagle or Operation Sinai Peninsula and were discharged under honorable conditions and were domiciled for six months in Massachu­ setts immediately prior to entry into the Armed Forces. DOR will then forward the name and ad­ dress to the Department of Veterans’ Services and the adjutant general of the Massachusetts National Guard to verify eligibility for any benefits you may be entitled to. Deceased Taxpayer If a taxpayer died during the taxable year, be sure to fill in the appropriate oval and enter the date of death. For further information, refer to the section How Do I File a Decedent’s Return? Under Age 18 If you are under age 18 as of January 1, 2026, be sure to fill in the oval(s). Name Change If you legally changed your name since the last time you filed a Massachusetts tax return, fill in the oval. Enclose a copy of your Social Security card or government-issued ID (i.e., driver’s license, passport, etc.) showing your new name. Failure to include this documentation could delay process­ ing of your return. Noncustodial Parent Fill in the oval if you are a noncustodial parent. A noncustodial parent is defined as a person who has a minor child, but does not live with the child. Note: If you are the biological parent of a child, but your parental rights have been terminated, you are not the noncustodial parent of that child. Custodial Parent Fill in the Custodial parent who has released claim to exemption for child(ren) oval if you are claiming the head of household filing sta­ tus and you have released your claim to one or more de pendent exemptions on U.S. Form 8332, or partic ipated in a decree or agreement to allow the non custodial parent to claim a dependency exemption.

2025 Form 1 Instructions 9 Schedule TDS. Inconsistent Filing Position Penalty Fill in the oval and enclose Schedule TDS, Tax­ payer Disclosure Statement, if you are disclosing any inconsistent filing positions. Schedule TDS is available on our website at mass.gov/dor. The in­ consistent filing position penalty (see TIR 06-5, Section IV) applies to taxpayers that take an incon­ sistent position in reporting income. These taxpay­ ers must “disclose the inconsistency” when filing their Massachusetts return. If such inconsistency is not disclosed, the taxpayer will be subject to a penalty equal to the amount of tax attributable to the inconsistency. This penalty is in addition to any other penalties that may apply. A taxpayer is deemed to have taken an “inconsis­ tent position” when the taxpayer pays less tax in Massachusetts based upon an interpretation of Massachusetts law that differs from the position taken by the taxpayer in another state where the taxpayer files a return and the governing law in that other state “is the same in all material respects” as the Massachusetts law. The Commissioner may waive or abate the penalty if the inconsistency or failure to disclose was attributable to reasonable cause and not willful neglect. Schedule FCI. Foreign Corporation Income Fill in the oval and enclose Schedule FCI (Foreign Corporation Income) if you are required to com­ plete and file Schedule FCI with your return. All tax­ payers with foreign corporation income (including Global Intangible Low-Taxed Income (GILTI)) must complete Schedule FCI. GILTI should be included in dividend income on Schedule B, Part 1, line 3. Detailed instructions for completing Schedule FCI are available on DOR’s website. See Schedule FCI and Instructions. Digital Assets Fill in the oval if at any time during 2025 you re­ ceived (as a reward, award, or payment for prop­ erty or services) a digital asset, or sold, exchanged, or otherwise disposed of a digital asset (or a fina­ cial interest in a digital asset) or if you received a Form 1099-DA. Digital assets include non-fungible tokens (NFTs) and virtual currencies, such as cryp­ tocurrencies and stablecoins. Note: Lines without specific instructions are con­ sidered to be self-explanatory. a. Total Federal Income Enter your total federal income (from U.S. Form 1040, line 9). If married filing separately and liv­ ing in the same household for the last 6 months of 2025, each spouse must com bine their income figures from their separate U.S. returns when completing this section, unless you did not live with your spouse on 12/31/2025 and were legally separated under a written separation agreement or a decree of separate maintenance. Do not combine your income figures if you are a victim of domestic abuse and living apart from your spouse at the time you file your return. If you did not have a requirement to file a U.S. re­ turn, you must enter 0 in this section. Note: Failure to enter this information will delay the processing of your return. b. Federal Adjusted Gross Income Enter your federal adjusted gross income (from U.S. Form 1040, line 11a). If married filing sep­ arately and living in the same household for the last 6 months of 2025, each spouse must com- bine their income figures from their separate U.S. returns when completing this section, unless you did not live with your spouse on 12/31/2025 and were legally separated under a written separation agreement or a decree of separate maintenance. Do not combine your income figures if you are a victim of domestic abuse and living apart from your spouse at the time you file your return. If you did not have a requirement to file a U.S. re­ turn, you must enter 0 in this section. Note: Failure to enter this information will delay the processing of your return. Line 1. Filing Status Note: More than one filing status may apply to you. If so, you may wish to figure your taxes based upon more than one filing status to see which status is to your benefit. Be sure to select only one filing status. Fill in the if not using same filing status on the federal return oval if you and your spouse filed a joint federal return but are not filing a joint Massa­ chusetts return. For tax years beginning on or after January 1, 2024, a consistent filing requirement exists which requires married couples to file a joint Massachusetts return in any year in which they file a joint federal return. If one of the spouses does not have a Massachusetts filing requirement be­ cause their Massachusetts gross income does not exceed $8,000, an exemption applies where they may choose the married filing separate return sta­ tus. To claim this exemption, fill in the "if joint filing exemption for spouses with Massachusetts gross income under $8,000" oval. Generally, a joint Form 1 is not allowed unless both spouses were Massa­ chusetts residents for the same portion of 2025. See TIR 24-4 for additional information. Single Fill in the Single oval if you were single as of De­ cember 31, 2025. This status applies to you if at the close of the taxable year you fit into any of the following categories: • You were unmarried; • You were a widow or widower whose spouse died before 2025; or • You were legally separated under a final judg­ ment of the probate court. Note: You are not single if: • You have obtained a judgment of divorce which has not yet become final; • You have a temporary support order; or • You and your spouse simply choose to live apart. Married Filing Joint Return Fill in the Married filing joint return oval if you were legally married as of December 31, 2025. Both spouses are responsible for the accuracy of all information entered on a joint return and both must sign. A joint return is allowed even if only one spouse had income or if one spouse died during 2025. For further information, refer to the section “What Are the Rules for Filing a Joint Return?” Married Filing Separate Return Fill in the Married filing separate return oval if you were legally married as of December 31, 2025, and if you and your spouse are not filing a joint return. Be sure to enter your spouse’s name and Social Security number in the space provided. If your spouse is a nonresident alien and does not have and is not required to have a Social Security number (SSN) or Individual Taxpayer Identifica­ tion Number (ITIN), fill in the NRA oval. Note: Only fill in the NRA oval if, on your U.S. 1040, you entered NRA in the space below the filing sta­ tus checkboxes to indicate that your spouse is a nonresident alien who does not have and is not re­ quired to have a SSN or ITIN. Head of Household Fill in the Head of household oval if you qualify to file this status federally. This status is for unmar­ ried people who paid over half the cost of keeping up a home for a qualifying person, such as a child who lived with you or your dependent parent. Be sure to include such qualifying person on Sched­ ule DI, Dependent Information. Certain married people who lived apart from their spouse for the last six months of 2025 and who meet all of the other federal requirements may also be able to use this status. See IRS Publication 501, Dependents, Standard Deduction, and Filing Information, for more information. Whole Dollar Method Required DOR requires that the whole dollar method be used for entries made on forms or schedules. For exam­ ple, amounts between $1.00 and $1.49 should be entered as $1.00 and amounts between $1.50 and $2.00 should be entered as $2.00. However, calcula­ tions on worksheets used to reach amounts shown on the return may be made in one of two ways: • Round amounts before adding them up and enter the resulting total on the form; or

2025 Form 1 Instructions 10 • Add amounts to the penny, and then round to the whole dollar for entry on the form. Either method is acceptable as long as one method is used consis­ tently throughout the return. Line 2. Exemptions Line 2a. Personal Exemptions Each taxpayer is entitled to claim a personal ex­ emption. The amount of your personal exemption depends on your filing status in line 1. • If you are single or married filing a separate re­ turn, enter $4,400 in line 2a. • If filing as head of household, enter $6,800 in line 2a. • If married filing a joint return, enter $8,800 in line 2a. Line 2b. Number of Dependents You may claim a $1,000 exemption for each of your dependents if you claimed them on your U.S. return. Enter in the box in item b the number of de­ pendents you listed on U.S. Form 1040. Do not in­ clude yourself or your spouse. Then, multiply that total by $1,000 and enter the total amount in line 2b. Be sure to fill out Schedule DI, Dependent In­ formation, if you are claiming a dependent exemp­ tion(s). Failure to do so will delay the processing of your return. Note: Only one person (or married couple filing jointly) may claim the dependent exemption for any one child or other dependent. Line 2c. Age 65 or Over Before 2026 You are allowed an additional $700 exemption if you were age 65 or over before January 1, 2026. If your spouse was age 65 or over and you are filing a joint return, you may also claim a $700 exemp­ tion for your spouse. Fill in the appropriate oval(s) and enter the total number of persons age 65 or over in the small box. Multiply that total by $700 and enter the total in line 2c. Line 2d. Blindness Exemption You are allowed an additional $2,200 exemption if you are legally blind. If your spouse is also legally blind and you are filing a joint return, you may also claim a $2,200 exemption for your spouse. Fill in the appropriate oval(s) and enter the total number of blindness exemptions in the small box. Multiply that total by $2,200 and enter the total in line 2d. Legal Definition of Blindness You are legally blind and qualify for the blindness exemption if your visual acuity with correction is 20/200 or less in the better eye, or if your periph­ eral field of vision has been contracted to a 10-de­ gree radius or less, regardless of visual acuity. Line 2e. Medical/Dental Expenses You may claim an exemption for medical and den­ tal expenses paid during 2025 only if you itemized these expenses on your U.S. Form 1040, Sched­ ule A. If you are married filing a joint U.S. Form 1040, you must file a joint Massachusetts Form 1 to claim this exemption. Enter in line 2e the amount reported on your U.S. Form 1040, Sched­ ule A, line 4. Line 2f. Adoption Agency Fee If you paid adoption fees to a licensed adoption agency during 2025, you are eligible for an exemp­ tion of the total amount of the fees paid during the year. Fees paid during 2025 to an agency licensed to place children for adoption on account of the adoption process of a minor child regardless of whether an adoption actually took place during 2025 should also be included for this exemption. Enter this amount in line 2f. 5.0% Income Note: DOR and the IRS maintain an extensive exchange program, routinely sharing computer tapes and audit results. Discrepancies between in­ come, deductions, and schedules reported feder­ ally and on this return, except those allowed under state law, will be identified and may result in a state audit or further investigation. Line 3. Wages, Salaries, Tips and Other Employee Compensation Report in line 3 total state wages and allocated tips from Form(s) W-2. Generally, your total wages and allocated tips will be the same amount reported on your U.S. Form 1040, line 1z. Note: Massachusetts does not adopt the federal deduction for tip income (IRC § 224) or the federal deduction for overtime pay (IRC § 225). The following are instances that require an adjust­ ment to these amounts: Massachusetts Residents Working in a Foreign Country Income earned by a Massachusetts resident in a foreign country is subject to taxation in Massachu­ setts. If you excluded part or all of the compensa­ tion earned in a foreign country on your U.S. re­ turn (under IRC § 911), you must include any such amount in line 3 for Massachusetts tax purposes. State or Local Employees Contributing to Pension Plans If you are a Massachusetts state, city, town or county employee and contributed to your pension plan, enter in line 3 the Massachusetts W-2 state wage amount. This is generally box 16 of Form W-2. This amount will be higher than the U.S. amount because your pension contributions are excluded from your income for U.S. tax purposes. Contributions up to $2,000 per taxpayer may be deducted in lines 11a and/or 11b. Medicaid Waiver Payments To the extent included in Form 1 line 3, enter in Schedule Y, line 9a the amount of Medicaid waiver payments reported on U.S. Schedule 1, line 8s to be excluded from Massachusetts wages. Line 4. Taxable Pensions and Annuities Income from most private pensions or annuity plans is taxable in Massachusetts. Certain gov­ ernment pensions, however, are exempt under Massachusetts law. In general, exempt pensions include contributory pensions from the U.S. Gov­ ernment or the Commonwealth of Massachusetts and its political subdivisions, and noncontributory military pensions. The following section describes some specific pensions which are exempt. If your pension is exempt, enter 0 in line 4 and note the source on the dotted line to the left. If your pension is not exempt, you should gen­ erally enter in line 4 the taxable amount reported on your U.S. Form 1040, line 5b. In some cases, however, Massachusetts law requires an adjust­ ment to the federal amount. Distributions from annuity, stock bonus, pension, profit-sharing or deferred payment plans or contracts described in §§ 403(b) and 404 of the IRC must be adjusted to account for your contributions (including rollover contributions) that have been previously taxed. Subtract from such income (as reported on your U.S. Form 1040, line 5a) the amount of your con­ tributions which was previously taxed by Massa­ chusetts until the total of your taxed contributions is received. If your pension falls into this category, enter the adjusted amount in line 4. If you are re­ ceiving distributions from an IRA or Keogh plan, do not report the income here; instead, see the instructions for Schedule X, line 2. Note: Massachusetts does not tax Social Security income; therefore, you should not report such in­ come on Massachusetts Form 1. What pensions are exempt? • Pension income received from a contributory annuity, pension, endowment or retirement fund of the U.S. Government or the Commonwealth of Massachusetts and its political subdivisions. • Pension income from other states or their po­ litical subdivisions which do not tax such income from Massachusetts, or its political subdivisions must be reported in line 4. However, this income may be eligible for a deduction on Schedule Y line 13. Refer to the instructions for Schedule Y line 13 to determine eligibility for this deduction. • Noncontributory pension income or survivor­ ship benefits received from the U.S. uniformed services (Army, Navy, Marine Corps, Air Force, Coast Guard, commissioned corps of the Public Health Service and National Oceanic and Atmo­

2025 Form 1 Instructions 11 spheric Administration) are exempt from taxation in Massachusetts. • Massachusetts state court judges who were appointed on or after January 2, 1975 are partic­ ipants in the Massachusetts contributory retire­ ment system and their pensions are nontaxable. State court judges who were appointed prior to January 2, 1975 receive taxable noncontribu­ tory pensions. If you retired under MGL ch 32, §§ 56–60 and are a veteran who began Massachusetts state service prior to July 1, 1939, all or part of your pension income may be subject to tax. If you elected to receive your proceeds from contributions in one lump-sum distribution, your original contributions to the retirement system are not taxable. Noncon­ tributory pension income received after a lump- sum distribution is fully taxable and should be re­ ported in line 4. How do I report lump-sum distributions? If you were an employee of the U.S., Massachu­ setts or one of its political subdivisions and left public employment prior to retirement, you are not required to report as income the lump-sum distribution of your previously-taxed pension contributions. Lump-sum distributions of qualified employee benefit plans in excess of the employee’s contribu­ tions which were previously subject to Massachu­ setts tax (or not previously excluded from Massa­ chusetts tax) must be reported in line 4. Generally, qualified rollovers are not taxable in Massachu­ setts to the extent they are not taxable on your U.S. return. Lump-sum distributions related to IRA/Keogh and Roth IRA distributions should be reported in Form 1, line 9, “Other Income (from Schedule X).” Rollover from a traditional IRA to a Roth IRA. Taxpayers are allowed to make partial or complete rollovers from existing IRAs to Roth IRAs. Any tax­ able portion of these rollovers included in federal gross income is also included in Massachusetts gross income, except for amounts previously sub­ ject to Massachusetts personal income tax. See Schedule X, line 2 instructions for further details. Line 5. Interest from Massachusetts Banks Enter in line 5 the total amount of interest received or credited to deposit accounts (term and time deposits, including certificates of deposit, savings accounts, savings shares, and NOW accounts) in Massachusetts banks. Do not subtract interest forfeited or penalties charged to you for early savings withdrawal. You will be al­ lowed to deduct these amounts on Schedule Y, line 2. All other interest, unless exempt, should be entered on Massachusetts Schedule B. Interest on an IRA/ Keogh is not taxable until distributed. Lines 6, 7 and 10 If showing a loss in lines 6, 7 or 10, be sure to mark over the X in the box to the left. Do not use parentheses or negative signs to indicate losses. Line 6a. Business/Profession Income or Loss Enter in line 6a the amount of income or loss from a business or profession from Massachusetts Schedule C, line 37. You must enclose Massachu­ setts Schedule C with this return. U.S. Schedule C is no longer allowed as a substitute for the Massa­ chusetts Schedule C. Note: Following the Code Update, you may not de­ duct an excess business loss (EBL) for tax year 2025. For federal purposes, your EBL, if any, is de­ termined using U.S. Form 461 and is added back to your income on U.S. Form 1040, Schedule 1, line 8p. You must also add back EBL to Massachu­ setts income. To do so, use Massachusetts Sched­ ule X, line 6. See instructions for that line for more information. Line 6b.

Rental, Royalty, REMIC, Part ner- ship, S Corporation, Trust Income or Loss Taxpayers with income or loss reported on a Schedule E must file his or her tax return using computer-generated forms produced by third- party software. The tax return may be generated by the taxpayer or by a tax professional. The tax­ payer is encouraged, but not required, to submit the return electronically. Paper forms produced using the third-party software product will con­ tain a two-dimensional (2D) bar code and will also be accepted. If the taxpayer hires an income tax preparer to complete the taxpayer’s taxes, the pre­ parer must follow the Commissioner’s electronic filing rules. See TIRs 08-22 and 16-9 for more information. If you do not have access to a software package when filing your 2025 income tax return, you may file your Schedule(s) E on paper.

Other Income (from Schedule X) Taxable Alimony Received, Taxable IRA/Keogh and Roth IRA Conversion Distributions, Other Gambling Winnings, Fees and Other 5.0% Income, PFML Taxable Distributions and Excess Business Loss Adjustment “Other 5.0% income” includes the items listed above and must be included on Schedule X. Enter the total from Schedule X, line 7. Not less than 0. Be sure to enclose Schedule X with your return. Failure to enclose this schedule will delay the processing of your return. Deductions Lines 11 through 15 Massachusetts allowable deductions differ from itemized deductions on Schedule A of U.S. Form 1040. You may claim only the deductions speci­ fied on Massachusetts Form 1, lines 11 through 14 and Schedule Y. You are not allowed to deduct amounts unless they are directly related to income that is subject to taxation and reported on Massachusetts Form 1. Line 11. Amount Paid to Social Security and Medicare (FICA), Railroad, U.S. or Massachusetts Retirement Systems If you have paid into any of the retirement systems listed above during 2025, you may deduct those contributions, up to a maximum of $2,000. Enter in lines 11a and 11b the amount you, and your spouse if filing jointly, paid to Social Secu­ rity (FICA), Medicare or Railroad Retirement and the U.S. or Massachusetts retirement systems during 2025 as shown on your Form W-2, but not more than $2,000 each. Payment amounts may not be combined or transferred from one spouse to the other. Be sure to add any amount of Medi­ care tax withheld as shown on Form W-2 and any amount of self-employment tax as reported on your U.S. Form 1040 to the amount of Social Se­

2025 Form 1 Instructions 12 curity tax withheld, the total not to exceed $2,000 per person. Note: Medicare premiums deducted from your Social Security or retirement payments are not deductible. Payments to an IRA, Keogh, Simplified Employee Pension Plan (SEP), or Savings Incentive Match Plan for Employees (SIMPLE) Account are not de­ ductible for Massachusetts income tax purposes. Line 14. Rental Deduction You may be entitled to a rental deduction equal to one-half (50%) of the rent you paid during 2025 (up to a maximum of $4,000 per return) for your principal residence in Massachusetts. Enter the total amount of qualified rent paid by you during 2025 in line 14a. Divide line 14a by 2 and enter the result, or $4,000 ($2,000 if married filing a sepa­ rate return), whichever is smaller, in line 14. Note: This deduction amount does not apply to your U.S. tax return. What Qualifies for the Rental Deduction? The deduction must be for rent you paid to a land­ lord for the rental or lease of your principal resi­ dence in Massachusetts. If two or more persons jointly rent a unit, each occupant using it as his/ her principal residence is entitled to a deduction based on the amount of rent that each person paid. If the rent is paid by a third party (such as a parent) who maintains a principal residence elsewhere, no 50% rental deduction is allowed for either party. A principal residence does not include any resi­ dence for vacation, an apartment for a person on a temporary assignment or a student or faculty member who has a principal residence elsewhere. It also does not include any apartment or house in Massachusetts of a nonresident who has a res­ idence in another state or country. Payment for occupying a hotel, motel or rooming house is not considered rent unless a rental agreement exists. Nor are payments by a tenant-stockholder of a co­ operative housing corporation to the corporation and payments by an owner of a condominium unit to the condominium association considered rent. All separately stated charges such as utilities, fur­ nishings or parking cannot be included in rent for purposes of this deduction. Also, rent does not include any advance payments (such as security deposit, last month’s rent, etc.) until actually ap­ plied as rent. How Do I Calculate My Rental Deduction If I Am Married Filing Separately? If married taxpayers file separate returns, they are each entitled to a rental deduction equal to 50% of the rent each pays, not to exceed $2,000 per return. However, a married couple filing sepa­ rately may allocate the rent deduction differently, provided the amount taken by each spouse does not exceed 50% of the rent actually paid by that spouse, and provided their combined rental de­ ductions do not exceed $4,000. If the allocation results in one spouse claiming a deduction in ex­ cess of $2,000, that spouse must enclose with his/ her return a statement signed by the other spouse indicating consent to the allocation. The statement must contain the name, address and Social Se­ curity number of the consenting spouse and the amount of rental deduction taken by that spouse. Line 15. Other Deductions (from Schedule Y) Enter the total from Schedule Y, line 19. Be sure to enclose Schedule Y with your return. Failure to do so will delay the processing of your return. Line 17. 5.0% Income After Deductions Subtract line 16 from line 10. Enter the result in line 17. If line 16 exceeds line 10, enter 0 in line 17. Line 19. 5.0% Income After Exemptions Subtract line 18 from line 17. If line 18 exceeds line 17, enter 0 in line 19.

Note: Personal income tax forms must provide an election to voluntarily pay tax at a rate of 5.85% on taxable income which would otherwise be taxed at a rate of 5.0%. The election to pay tax at the rate of 5.85% does not apply to items of income taxed at 8.5% (short-term capital gains) and 12% (gains on collectibles).

Complete and enclose Schedule CRS, Credit Recapture Schedule. Line 26. Additional Tax on Installment Sale An addition to tax applies for taxpayers who have deferred the gain, and the tax associated with that gain, on certain installment sales. This addition to tax is measured by an interest charge on the tax that has been deferred. Include in line 26 an additional tax amount rep­ resenting an interest charge on the deferred tax on gain from certain installment sales with a sales price over $150,000 if you are not a dealer and the aggregate face amount of installment obligations arising during the tax year and outstanding as of the close of the tax year exceeds $5 million. For more information see MGL ch 62C, § 32A (a) and IRC § 453A (a)–(c). Also include in line 26 an additional tax amount representing an interest charge on the deferred gain from the installment sale of timeshares and residential lots, if the sale meets one of the follow­ ing criteria: • The sale is of a timeshare right for six weeks or less; • The sale is for the recreational use of specified campgrounds; or • The sale is for a residential lot and neither the dealer nor someone related to the dealer is obli­ gated to make any improvements on the lot. Note: If you have installment sales occurring be­ tween January 1, 1996 and December 31, 2002, you must complete and submit Schedule D-IS. For more information see MGL ch 62C, § 32A (b) and IRC § 453(l)(2)(B). If you are a partner in a partnership or a share­ holder in an S corporation, the entity is required to send you the information you need to calculate the addition to tax under this provision. To the extent practicable, Massachusetts follows federal income tax rules in determining the de­ ferred gain from installment sales subject to the interest-charge addition to tax.

The Fund also provides training to municipal animal control offi­ cers so that they can safely and effectively protect animals and people in their communities. Line 34. Massachusetts Use Tax Due On Internet, Mail Order and Other Out-of- State Purchases Made in 2025 If you purchased taxable tangible personal prop­ erty out of state, over the Internet or from a catalog and did not pay Massachusetts sales tax at pur­ chase, a Massachusetts use tax is due. If an item is exempt from sales tax (such as food, or clothing that costs $175 or less), it is exempt from use tax. If you paid a sales or use tax to another state or territory of the United States when purchasing this item, you are generally entitled to a credit against the Massachusetts use tax, up to 6.25%. See TIR 03-1 for more information. No credit is allowed for a value-added tax (VAT) paid to another country. The following are items that are often purchased without paying sales tax. Residents owe use tax based on the purchase price. • Electronics • Software • Appliances • Computers • Furniture • CDs and DVDs

2025 Form 1 Instructions 16 • Jewelry • Video games • Books • Carpet • Artwork • Antiques For example: You purchased several DVDs on the Internet for $100 and paid no sales tax. Your use tax liability to Massachusetts on these items is $6.25 ($100 x .0625 = $6.25). You purchased a computer for $1,550 from a seller located outside of Massachusetts and paid no sales tax. Your use tax liability to Massachusetts on this item is $96.88 ($1,550 x .0625 = $96.88). Taxpayers may choose the safe-harbor option for purchases of individual items each having a total sales price of less than $1,000. The safe-harbor provision makes it easier to comply with the use tax law by allowing taxpayers to self-report an es­ timated amount of use tax based on the average amount of online and/or out of state purchases a taxpayer in their income bracket would likely make during the year. Taxpayers do not need to keep re­ ceipts with safe-harbor reporting and will not be assessed additional use tax if audited, even if the actual amount of use tax due is greater than the safe-harbor amount reported. Mass AGI per return* Use tax liability $ 0 – $ 25,000 $ 0 25,001 – 40,000 20 40,001 – 60,000 31 60,001 – 80,000 44 80,001 – 100,000 56 If the Massachusetts AGI per return* is more than $100,000, multiply by .000625. *From line 7 of Massachusetts AGI worksheet. If you did not purchase any items with a total sales price of $1,000 or more, you may enter the safe-harbor amount from the table above directly on Form 1, line 34. Complete the following Form 1, line 34 Worksheet to calculate your use tax if you are not reporting a safe-harbor amount or if you purchased any individual items with a sales price of $1,000 or more. If you did purchase items with a sales price over $1,000 and you are reporting a safe-harbor amount, add the amount from the worksheet line 4 to the safe-harbor amount. Form 1, Line 34 Worksheet.

Line 40. 2025 Massachusetts Estimated Tax Payments If you paid Massachusetts estimated income tax for 2025, enter in line 40 the total of all Massachu­ setts estimated tax payments. Be sure to include any last quarter (of 2025) payment made on or before January 15, 2026. Do not include any 2024 overpayment applied to your 2025 estimated tax. Every resident who expects to pay more than $400 in Massachusetts income tax on income which is not covered by Massachusetts withholding must pay Massachusetts estimated taxes. Estimated tax payments can be made online by using MassTax­ Connect by visiting mass.gov/dor or by filing Mas­ sachusetts Form 1-ES. Income that is not subject to withholding includes: • Salaries and wages where the employer is not subject to Massachusetts withholding; • Dividends and interest, including interest from Massachusetts banks; • Gains from capital assets; • Income from an individual trade, business or profession; • Income from any estate or trust not taxed directly; • Certain pensions; • Taxable Keogh or IRA distributions (only if you elected not to have federal withholding); • Rental, royalty or REMIC income; • Unemployment compensation (from which no Massachusetts income tax was withheld); • Taxable alimony received; • Distributions from SIMPLE accounts; • Illegal income; and

2025 Form 1 Instructions 17 • Any other income received while a Massachu­ setts resident from which Massachusetts tax will not be withheld. Generally, the first payment must be filed on or before April 15 of the taxable year. The estimated tax may be paid in full with the first payment or in four installments on or before April 15, June 15, September 15 of the current taxable year and Jan­ uary 15 of the following year. You may verify estimated tax payments that have already been made through your MassTax­ Connect account. If you don’t have a MassTax­ Connect account, you can sign up at mass.gov/ masstaxconnect. You may request that your employer withhold ad­ ditional amounts from your salary on Form M-4, Massachusetts Employee’s Withholding Exemp­ tion Certificate to cover the taxes on other in­ come so that you do not have to file and pay es­ timated taxes. If 80% of the tax is not paid throughout the year through withholding and/or estimated payments, a penalty may be imposed. Line 41. Payments Made with Extension If you filed Massachusetts Form M-4868, Appli­ cation for Automatic Six-Month Extension of Time to File Massachusetts Income Tax Return, or made an electronic extension payment for 2025 on or before April 15, 2026, enter in line 41 the amount you paid with Massachusetts Form M-4868. Line 42. Payments Made with Original Return (amended return only) Use this line only if you are amending the original return. Enter in line 42 the amount of tax you paid with the original return from line 55, “Tax Due.” If estimated tax payments were made on the orig­ inal return, they should be reflected on line 40, as on the original return. Select the appropriate Amended return oval on page 1. Complete the entire return, correct the appropriate line(s) with the new information and recompute the tax liabil­ ity. On an enclosed sheet, explain the reason for the amendment(s) and identify the line(s) and amount(s) being changed on the amended re­ turn. Mail the amended return to Massachusetts Department of Revenue, PO Box 7000, Boston, MA 02204. If you owe additional tax, mail the amended return to Massachusetts Department of Revenue, PO Box 7003, Boston, MA 02204. Line 43. Earned Income Credit The Earned Income Credit (EIC) is a tax credit for certain taxpayers who work and have earned in­ come under $68,675 (maximum amount may be lower depending on filing status and number of eligible children). Taxpayers who qualify for and claim the federal EIC are allowed a refundable credit equal to 40% of the federal amount. If the credit due the taxpayer exceeds the amount of the total income tax payable for the year by the tax­ payer, the excess amount of the credit will be re­ funded to the taxpayer without interest. You must enter the number of qualifying children, if any, in line 43a. Then, enter in line 43b the federal EIC amount from your U.S. Form 1040, line 27a. Mul­ tiply this amount by 0.40 (40%) and enter the result in line 43. Be sure to fill out Schedule DI, Dependent Information, if you are claiming this credit for one or more qualifying children/depen­ dents. Failure to do so will delay the processing of your return. If you choose to have the IRS compute your fed­ eral EIC, wait until the IRS notifies you of that amount before making an entry in line 43. If you do not receive this information before April 15, 2026, and you are expecting a refund, you may have ad­ ditional time to file your return. See When to File Your Return on page 6 for more information. For more information about the federal EIC, see IRS publication 596, available at irs.gov. Note: If you are considered married for federal and Massachusetts income tax purposes, you gener­ ally must file a joint return with your spouse to claim the EIC. However, recent federal legislation has expanded this beginning with tax year 2022. Massachusetts adopts the expansion of the fed­ eral EIC in calculating the Massachusetts EIC. In addition, even if you don't qualify under the newly expanded rules, if you are a victim of domestic abuse you may file a return as married filing sep­ arately and still claim the EIC in Massachusetts if the following apply to you: • You are living apart from your spouse at the time you file your tax return; and • You are unable to file a joint return because you are a victim of domestic abuse. If you have a filing status of married filing sepa­ rately and you claim the EIC under the Massachu­ setts exception, you should keep records demon­ strating the existence of domestic abuse. What constitutes adequate records will vary depend­ ing upon your circumstances. Some examples of documents that may meet this record-keeping re­ quirement include (do not enclose these records with your tax return): • Protective and/or restraining order; • Police report; • Doctor’s report or letter; • A statement from someone who was aware of, or who witnessed, the abuse or the results of the abuse. The statement should be notarized if possible; or • A sworn statement from you attesting to the abuse. To claim this exception, you must fill in the oval on line 43. To determine if you qualify for the credit with a filing status exception as a victim of do­ mestic abuse, you should complete the IRS EIC worksheet. Note: You should answer No to question 4 of the EIC worksheet and when looking up the amount of the credit in the EIC table you should use the col­ umn for the filing status “single” and the number of children you have. To determine line 43, “Amount from U.S. return”: • U.S. Form 1040, EIC Worksheet A filers should use the amount from Worksheet A, line 6. • U.S. Form 1040, EIC Worksheet B filers should use the amount from Worksheet B, line 11. See TIR 17-10 for more information. Line 44. Senior Circuit Breaker Credit Certain senior citizens in Massachusetts may be eligible to claim a refundable credit on their state income taxes for the real estate taxes paid on the Massachusetts residential property they own or rent and which they occupy as their principal resi­ dence. The maximum credit allowed is $2,820 for the tax year beginning January 1, 2025. If the credit due the taxpayer exceeds the amount of the total income tax payable for the year by the taxpayer, the excess amount of the credit will be refunded to the taxpayer without interest. To determine if you qualify for this credit, refer to the Senior Circuit Breaker Credit instructions in this booklet. If you qualify for this credit and you are a home­ owner, enter the amount from Schedule CB, Circuit Breaker Credit, line 17; if you are a renter, enter the amount from line 21. Be sure to complete and en­ close Schedule CB with your return. Line 46. Child and Family Tax Credit You may claim a credit of $440 for an individual who is (1) under the age of 13 and who qualifies for exemption as a dependent for federal purposes; (2) a dependent, or the taxpayer’s spouse, who is physically or mentally incapable of taking care of himself or herself and principally lives with the tax­ payer; or (3) a dependent who is age 65 or over or disabled. Starting with tax years beginning on or after January 1, 2024, a noncustodial parent may claim the credit with respect to a child dependent that is age 13 or older and who is physically or mentally incapable of caring for himself or herself. Enter the number of qualified dependents in line 46a and multiply that amount by $440. Enter the result in line 46. You may only claim the credit if you file as single, head of household, or married filing jointly. You cannot claim this credit if you file as married filing separately.

2025 Form 1 Instructions 18 Line 47. Other Refundable Credits Enter in line 47 the amount from Schedule CMS, Credit Manager Schedule. Be sure to enclose Schedule CMS with your re­ turn. Failure to do so will delay the processing of your return. For more information on Sched­ ule CMS, refer to the Schedule CMS instructions on page 32. Line 49. Excess Paid Family Leave Withholding Businesses are required to withhold Paid Family and Medical Leave (PFML) contributions from employees and individuals whose payments for services are reported on U.S. Form 1099-MISC (1099-MISC workers) up to the annual income limit set by the Social Security Administration for the Social Security Program. Self-employed individuals not otherwise covered by PFML may opt to participate in the PFML pro­ gram and pay PFML contributions from their net earnings from their self-employment income, sub­ ject to this same limitation. For the 2025 tax year, the income limit is set at $176,100 and the maxi­ mum PFML contribution amount for most individ­ uals is $810.06. For a self employed individual not subject to PFML withholding who opts into PFML, the maximum PFML contribution is $1,549.68. A single employer may not withhold, and a self-employed individual may not contribute, more than the maximum PFML contribution amount in a tax year. If a single employer withholds more than the maximum yearly PFML contribution amount, the employee should contact their employer di­ rectly regarding a refund. If your PFML contri­ butions or the amount of PFML contributions withheld on your behalf during the tax year ex­ ceeded the maximum PFML contribution amount, or you are self-employed and your contributions were made based on your gross earnings and did not take into account your business expenses, you may have excess PFML contributions that entitles you to seek a credit on your individual tax return, subject to certain requirements. W-2 filers: If you worked for two or more Mas­ sachusetts businesses that each remitted PFML contributions on your behalf during the 2025 tax year, and the total amount of your combined Mas­ sachusetts W-2 wage income exceeded $176,100, you should complete the worksheet below to de­ termine if you have excess PFML withholding. The PFML law follows the unemployment statute, for determining what counts as wages. If all of the wages reported on your W-2s are subject to PFML withholding, you should use the greater of Box 3 (Social Security Wages) or Box 5 (Medicare Wages) when completing the worksheet. If a portion of your wages are not subject to PFML withholding, you should reduce your Box 3 (Social Security Wages) or Box 5 (Medicare Wages) by any wages that were not subject to PFML withholding. To be eligible for a credit the total PFML contribution amount remit­ ted on your behalf must exceed $810.06. If only one employer withheld PFML contributions, and your PFML contributions exceeded the proper amount due, you must seek reimbursement from your employer. You are not eligible to claim a credit on line 49. 1099-MISC workers: If you worked for one or more Massachusetts businesses that remitted PFML contributions on your behalf based on your 1099-MISC gross earnings during the 2025 tax year, you should complete the work sheet below to determine if you have any excess PFML contributions. Self-employed individuals that opt in to PFML: If you are a self-employed individual that has opted to participate in the PFML program, your required PFML contributions are based on your net earn­ ings from self-employment. You may complete the worksheet below to determine if you have any ex­ cess PFML contributions. Joint returns: The maximum PFML contribution amount applies on an individual basis. If filing a joint return, figure the amount of excess PFML withholding separately for each spouse and enter the combined total. For more information about the PFML program, including how PFML contributions are calculated, see the Department of Family and Medical Leave’s (DFML) regulation at 458 CMR 2.00, and DFML’s website at mass.gov.

Enclose Schedule 62-WH and Form(s) NRW with your return if Massachusetts income tax was withheld, failure to do so may delay the processing of your return. Refund Amount Line 53. Amount of Overpayment You Want Applied to Your 2026 Massachusetts Estimated Tax Enter the amount of your 2025 overpayment that you wish to apply to your 2026 Massachusetts es­ timated tax. Once an election is made to apply your overpayment to your 2026 estimated tax, it cannot be refunded after the due date of the return or ap­ plied to any additional tax you may owe for 2025, including any tax due on an amended return. The amount entered in this line can only be claimed as a credit on your 2026 Massachusetts return. Note: This amount cannot be changed on an amended return. Line 54. Refund Amount Subtract line 53 from line 52. Enter the result in line 54. This is the amount of your refund. Note: Your state tax refund may be taxable on your federal tax return if you deducted state income tax paid as an itemized deduction on U.S. Schedule A. You may elect to have your refund deposited di­ rectly into your savings or checking account. Check with your financial institution to make sure that it accepts direct deposit and verify the routing

2025 Form 1 Instructions 19 transit number (RTN) of the issuing financial insti­ tution. If we are unable to honor your request for a direct deposit, a paper check will be sent to you. The routing number of your financial institution is nine digits and begins with 01 through 12 or 21 through 32. The account number can be up to 17 characters (both numbers and letters). Omit hyphens, spaces and special symbols. Enter the number from left to right and leave any unused boxes blank. You must enter the routing number and the account number in the spaces provided in line 54 if you are requesting direct deposit. Failure to do so will result in your request for direct de­ posit being denied. Tax Due Line 55. Tax Due If line 37 is larger than line 51, subtract line 51 from line 37, and enter the result in line 55. This is the amount of tax you owe with your return. Pay in full with your return. Go to mass.gov/masstax­ connect for online payment options. If you need to mail your payment, make your check or money order payable to the Commonwealth of Massachu­ setts and write your Social Security number on the front of your check or money order in the lower left corner. Enclose the check with your return. Be sure to use the light blue mailing label when mail­ ing your Form 1. Failure to file or failure to pay the proper amount of tax when due will result in an increasing amount of interest and penalties. It is to your advantage to file when your return is due, whether or not you are able to make full payment. If you owe any interest, penalty or addition for the underpayment of estimated tax, add those amounts to the tax you owe when making your payment. What Are Interest and Penalties? Interest. If you fail to pay the tax when due, in­ terest will be charged. For an explanation of how interest is compounded in Massachusetts, see TIR 92-6, available at mass.gov/dor. Penalty for late payment. The penalty for late pay­ ment is 1% per month (or fraction thereof) of the tax due, up to a maximum of 25%. Penalty for failure to file. The penalty for failure to file a tax return by the due date is 1% per month (or fraction thereof) of the tax due, up to a maxi­ mum of 25%. If you were required to file a tax re­ turn for income received in any prior year and you did not file, you must file for that prior year. Penalty for protested (“bad”) payment. If your payment is not honored by your bank because of insufficient funds or any other reason, a penalty may be added of $30 or the amount of the pay­ ment, whichever is less. Addition for underpayment of estimated tax. You will generally be subject to this addition to tax if you did not have withholding and/or estimated payments equal to 80% of the total tax liability re­ quired to be paid and your 2025 tax due after cred­ its and withholding is greater than $400. The 80% requirement is reduced to 66.67% for individuals who receive two-thirds of their income from fish­ ing or farming. If you failed to meet these require­ ments, you must complete and enclose Massa­ chusetts Form M-2210 to calculate the amount you must add to line 55. You do not have to com­ plete Form M-2210 if the balance due with your return is $400 or less. You may not be subject to an underpayment penalty if you qualify for one of the following exceptions: • You are a qualified farmer or fisherman and are paying the full amount of the tax due on or before March 1, 2026; • You were a Massachusetts resident and were not liable for 2024 taxes (where the taxable year was 12 months); or • The sum of your estimated payments and with­ holding equals or exceeds your 2024 tax (where the taxable year was 12 months and a return was filed). If you qualify for one of these exceptions, fill in the Exception oval under line 55 on Form 1 and enclose Form M-2210 indicating which of the ex­ ceptions applies to your circumstances. A limited number of taxpayers may also qualify for a waiver of the underpayment penalty for one or more installments if: • The underpayment was because of casualty or disaster; or • During 2024 or 2025 you retired after reach­ ing age 62 or became disabled and the underpay­ ment was due to reasonable cause and not will­ ful neglect. If you think you qualify for one of these waivers, go to mass.gov/dor and use DOR’s online ap­ plication for abatement return or enclose Form M-2210 and an explanatory statement with your return and fill in the Exception oval under line 55. If your waiver is not for all four installments, com­ plete Form M-2210 to calculate the underpayment penalty for the installments which are not covered by the waiver. Form M-2210 is available by visiting mass.gov/dor. Penalty for failure to report federal change. If the IRS changes your federal taxable income for a prior year (generally through audit), file an amended return within one year of the final fed­ eral determination to avoid this penalty. This pen­ alty is equal to 10% of the additional tax due. If the change indicates a refund, you must file an amended return within one year of federal determi­ nation, including acceptance of an amended fed­ eral return by the IRS. Sign Here Now that you have completed Form 1, sign your name at the bottom of page 1 of Form 1. Your spouse must also sign if this is a joint return. Write the date you signed the return. Note: Be sure to include all four pages of Form 1, as well as Schedule HC and all other applicable schedules. Enclose with your Form 1 Schedule 62-WH and all state copies of your Forms W-2, 1099, PWH-WA, W-2G, 2G, NRW and Schedule K-1s which in­ cluded Mas sachusetts withholding, failure to do so may delay the processing of your return. Go to mass.gov/masstaxconnect for online payment op­ tions. If you need to mail your payment, make your check or money order payable to Commonwealth of Massachusetts and be sure to sign the check and write your Social Security number on it. Also, be sure to use the light blue mailing label when mailing your Form 1 with a payment. Paid Preparer Must Sign Your Return Generally, anyone you pay to prepare your return must sign it in the space provided at the bottom of page 4 of the Form 1. Tax return preparers are authorized to sign the return by means of a rubber stamp, mechanical device, or computer software program, which must include either a facsimile or printed name of the preparer. Preparers are per­ sonally responsible for affixing their signatures to returns. Preparers must also provide their Social Security number (SSN) or Preparer Tax Identifica­ tion Number (PTIN) and Employer Identification Number (EIN) in the spaces provided at the bot­ tom of page 4 of the Form 1. The preparer must give you a copy of the return for your records. Someone who prepares your return but does not charge you should not sign your return. Paid Preparer Authorization If you want to allow the DOR to discuss your 2025 tax return with the paid preparer who signed it, fill in the Yes oval in the signature area of the return at the bottom of page 4 of the Form 1. This autho­ rization applies only to the individual whose signa­ ture appears in the paid preparer section of your return. It does not apply to the firm, if any, shown in that section. If you fill in the Yes oval, you, and your spouse if filing a joint return, are authorizing DOR to call the paid preparer to answer any questions that may arise during the processing of your return. You are also authorizing the paid preparer to: • Give DOR any information that is missing from your return;

2025 Form 1 Instructions 20 • Call DOR for information about the processing of your return or the status of your refund or pay­ ment(s); and • Respond to certain DOR notices that you have shared with the preparer about math errors, off­ sets and return preparation. The notices will not be sent to the preparer. You are not authorizing the paid preparer to receive any refund check, bind you to anything (including any additional tax liability), or otherwise repre­ sent you before DOR. If you want to expand the paid preparer’s authorization, see Form M-2848, Power of Attorney and Declaration of Represen­ tative. Form M-2848 is available at mass.gov/dor. The authorization cannot be revoked. However, the authorization will automatically end no later than the due date (without regard to extensions) for fil­ ing your 2026 tax return. This is April 15, 2027 for most people. E-File Opt Out Income tax return preparers who completed more than 10 original Massachusetts Forms 1 and 1-NR/PY (including those E-filed) during the pre­ vious calendar year are required to use electronic means to file all personal income tax returns, un­ less the taxpayer specifically directs on the paper form that the filing be on paper and signs Form EFO, Personal Income Tax Declaration of Paper Filing. Fill in the oval at the bottom of page 4 of Form 1 if you do not want your preparer to file your return electronically. See TIR 11-13 for more information. Mailing E-filing is the fastest most efficient way to sub­ mit your return and to receive your refund. How­ ever, if you are mailing your return follow these guidelines: • If you are expecting a refund or if you have no tax due, use the white mailing label on the back of the envelope that came with this booklet. If you do not have one, mail your original or amended Form 1 to Massachusetts Department of Revenue, PO Box 7000, Boston, MA 02204-7000. If using a tax software product, be sure to use the correct PO box. See the inside front cover for this information. • If you have a tax due, use the light blue mail­ ing label on the back of the envelope that came with this booklet. If you do not have one, mail your original or amended Form 1 to Massachusetts De­ partment of Revenue, PO Box 7003, Boston, MA 02204-7003. If using a tax software product, be sure to use the correct PO box. See the inside front cover for this information. Note: Schedule lines without specific instructions are considered to be self-explanatory. Be sure to list on each schedule the name and Social Security number that appears first on Form 1. Do not cut or separate schedules. Schedule DI Dependent Information Be sure to enclose with Form 1. You must complete this schedule if you are claim­ ing a dependent exemption(s) on Form 1, line 2b or taking a credit(s) on Form 1, lines 43 or 46 (if applicable). Failure to pro vide this information will delay the processing of your return. You must complete the information for each dependent. In the spaces provided enter the name, Social Se­ curity number, date of birth and the relationship of the dependent to you (son, daughter, mother, father, etc.). Also, if the dependent is a qualifying child for the Earned Income Credit, fill in the oval. If you are claiming more than 10 dependents, en­ close a statement listing the name, Social Security number, date of birth and the relationship of the dependent to you and if the dependent is a quali­ fying child for the Earned Income Credit. Schedule X Other Income Be sure to enclose with Form 1. Line 1. Taxable Alimony Received Enter in Schedule X, line 1 the total amount of taxable alimony and separate maintenance re­ ceived as reported on U.S. Form 1040, Schedule 1, line 2a. Note: Payments specified as child support are not taxable. Line 2. Taxable IRA/Keogh, Qualified Charitable IRA Distributions and Roth IRA Conversion Distributions Complete the Schedule X, Line 2 Worksheet to calculate the taxable portion of any amount you received from an Individual Retirement Account (IRA), Keogh, qualified charitable IRA distribution or Roth IRA conversion distribution. Since Massa­ chusetts does not allow a deduction for amounts originally contributed to an IRA or Keogh, the dis­ tributions are not taxable until the full amount of your contributions (including rollover contribu­ tions) which were previously subject to Massa­ chusetts taxes are recovered. Contributions made to Keogh accounts prior to 1975 were deductible when made. Therefore, no deduction may be taken from a Keogh distribution for amounts contributed before 1975. Note: Contributions from a deferred plan, such as a 401(k), that were rolled over into an IRA are gen­ erally not considered previously taxed contribu­ tions and are generally fully taxable upon distribu­ tion. Contributions from a deferred plan, such as a 401(k), that were converted into a Roth IRA and were taxed at the time of the conversion are gen­ erally considered previously taxed contributions when distributed.

See Sched­ ule Y, line 17 and TIR 15-14 for more information. Note: Do not report Massachusetts state lottery winnings in Schedule X, line 3. Instead, report them on Form 1, line 8b. Line 4.

Also, re­

2025 Form 1 Instructions 21 port all bartering income not reported on Sched­ ule C (the fair market value of goods or services received in payment for your services). • All prizes and awards won in a quiz program, drawing, beauty contest, etc. are taxable at fair market value. Awards and bonuses received from your employer for performance of services not part of a qualified award plan are also taxable. • Forgiveness of debt and mortgage forgiveness. • Research and experimental expenses disallowed as a deduction on Schedule C, line 26 or Schedule E, Line 16. • Other Massachusetts 5.0% income reported on U.S. Form 1040, Schedule 1, line 9 and not re­ ported elsewhere in Form 1, lines 3 through 8 or Schedule X, lines 1 through 3 must be reported in line 4 of Schedule X. Note: Do not include U.S. Shareholders IRC § 965(a) inclusion amounts that are included in the U.S. Form 1040, Schedule 1, line 9 in line 4 of Schedule X. These amounts are included in Sched­ ule B, see Schedule FCI for additional details and instructions. • Pre-1996 installment sales classified as ordi­ nary income for Massachusetts purposes (from Massachusetts Schedule D, line 10) are taxed as 5.0% income and must be reported on line 4 of Schedule X. • Embezzled or other income from illegal activi­ ties is taxable and should be reported on Schedule X, line 4. • Any benefits paid to you by a union as strike or lockout benefits to the extent included on U.S. Form 1040, line 1h.

A net operating loss from a business or profession cannot be car­ ried forward or backward to offset individual in­ come in any other year under Massachusetts law. • Refunds of U.S. and Massachusetts income taxes are not considered income under Massachu­ setts law. If you received interest on refunds, re­ port such interest on Massachusetts Schedule B. Line 5. PFML Taxable Distributions Enter in Schedule X, line 5 all income received from the Department of Family and Medical Leave. The amount should be in box 1 of the 1099-G issued to you by the Commonwealth Of Massachusetts, MA Department of Family and Medical Leave. Line 6. Excess Business Loss Adjustment For tax year 2025, taxpayers must report on Schedule X, line 6 any excess business loss (EBL) stated on U.S. Form 1040, Schedule 1, line 8p. Generally, EBL is the amount by which the total deductions attributable to a taxpayer’s trades or businesses exceed the sum of (i) the taxpayer’s total gross income and gains attributable to those trades or businesses and (ii) a threshold amount of $313,000 for single filers and $626,000 for joint returns. Differences between Massachusetts and federal income and deductions (e.g., bonus depre­ ciation) should be taken into account by adjusting the amount reported on Massachusetts Schedule X, line 6. Explain any difference between amounts reported on Massachusetts Schedule X, line 6, and on U.S. Schedule 1, line 8p, using Massachusetts Schedule TDS. Unlike on federal returns, you may not carry forward disallowed EBL because those losses are treated, for federal purposes, as net op­ erating losses, which are not allowed as a Massa­ chusetts deduction. Schedule Y Other Deductions Be sure to enclose with Form 1. Line 2. Penalty on Early Savings Withdrawal If you were charged a penalty because of early withdrawal of savings, and interest on the savings that such a penalty relates to is income reported in line 5 or line 20 of this return or on a prior-year Massachusetts return, you may deduct the pen­ alty.

Self-Employed Health Insurance Enter in Schedule Y, line 7 the amount from U.S. Form 1040, Schedule 1, line 17. Note: The amount on Schedule Y, line 7 should be the same as the amount on U.S. 1040, Schedule 1, line 17. If you elected to claim the federal credit for health insurance costs and were required to reduce the U.S. Form 1040, Schedule 1, line 17 deduction by the amount of the federal credit, you may not add the federal credit to the amount on Schedule Y, line 7. Line 8. Health Savings Accounts Enter in Schedule Y, line 8 the amount from U.S. Form 1040, Schedule 1, line 13. Line 9. Other Qualified Deductions You may claim only the deductions listed below for Schedule Y, line 9. 9a Certain qualified deductions from U.S. Form 1040.

2025 Form 1 Instructions 22 9b Business Expenses of National Guard and Reserve Members, Performing Artists, and Fee-Basis Government Officials; Impairment-re­ lated Work Expenses of Persons with Qualifying Disabilities. Note: No deduction is allowed to a taxpayer who files a joint federal income tax return unless a MA joint return is also filed. MGL, ch 62, § 2(d)(2). Enter the sum of 1) the amount from U.S Form 1040, Schedule 1, line 12; and 2) certain impair­ ment-related work expenses included on U.S. Form 1040, Schedule A, line 16. If you're a National Guard or Reserve member who has to travel more than 100 miles from home to perform services as a National Guard or Re­ serve member, you're allowed a deduction for unreimbursed overnight travel, meals and lodg­ ing expenses. If you perform services as an official state or local government employee, and you're compensated in whole or part on a fee basis, you're allowed a deduction for the expenses you paid related to those services. Generally, this applies to officials who provide certain services to the government, and who hire employees and incur expenses related to their of­ ficial duties. If you meet the federal qualifications to be con­ sidered a qualified performing artist, you're al­ lowed a deduction for expenses you paid related to your performances. Impairment-related Work Expenses of Persons with Qualifying Disabilities are the allowable ex­ penses of an individual with physical or mental disabilities for attendant care at his or her place of employment. They also include other expenses in connection with the place of employment that enable the employee to work. Employees who are not salespersons who so­ licit business for an employer away from the em­ ployer's place of business may only report im­ pairment-related expenses from U.S. Form 1040, Schedule A, line 16 that are expenses of travel, meals, and lodging while away from home, or ex­ penses of transportation 9c Charitable Contribution Deduction. Mas­ sachusetts allows a charitable deduction in an amount equal to the federal charitable deduc­ tion, except that the state deduction does not in­ clude any amounts for contributions of household goods or used clothing. Taxpayers do not have to itemize their deductions for federal tax purposes to claim the Massachusetts deduction. The Massachusetts deduction may only be used to reduce Part B adjusted gross income – e.g. wages – and cannot be used to reduce capital gain, divi­ dend, or interest income other than interest from Massachusetts banks. Taxpayers must keep records to substantiate cash and non-cash charitable contributions to the same extent as specified in U.S. Form 1040, Schedule A instructions. On line 9c, enter the amount entered on U.S. Form 1040, Schedule A, line 14, excluding the value of household goods or used clothing. If you did not itemize deductions on your U.S. re- turn, enter on line 9c the amount you would have entered on U.S. Form 1040, Schedule A, line 14 (excluding the value of household goods or used clothing) if you had itemized. If you deduct more than $500 of non-cash con­ tributions, you must complete and attach U.S. Form 8283. Line 10. Student Loan Interest Deduction Enter the amount from U.S. Form 1040, Schedule 1, line 21, not to exceed $2,500. This deduction is only allowed if not claiming the same expenses in line 12 of Schedule Y, Undergraduate Student Loan Interest Deduction. Line 11. College Tuition Deduction A deduction is allowed for tuition payments paid by you, for yourself or a dependent, to a qualifying two- or four-year college leading to an undergrad­ uate or associate’s degree, diploma or certificate. Tuition payments for students pursuing graduate degrees at such a college or university are not eligible for the college tuition deduction. The de­ duction is equal to the amount by which the tuition payments, less any scholarships, grants or finan­ cial aid received, exceed 25% of Massachusetts AGI. The amount of the college tuition deduction is limited to qualified tuition expenses paid during a taxable year in connection with an academic term beginning during such taxable year or during the first three months of the next taxable year. Qualified tuition expenses include only those ex­ penses designated as tuition or mandatory fees required for the enrollment or attendance of the taxpayer or any dependent of the taxpayer at an eligible educational institution. No deduction is al­ lowed for any amount paid for room and board, books, supplies, equipment, personal living ex­ penses, meals, lodging, travel or research, ath­ letic fees, insurance expenses or other expenses unrelated to an individual’s academic course of in­ struction. Also, no deduction is allowed for reim­ bursements or refunds of qualified tuition and re­ lated expenses made by an insurer.

Line 12. Undergraduate Student Loan Interest Deduction A deduction is allowed for interest paid on a quali­ fied undergraduate student loan. To be eligible for the deduction, the “education debt” must be a loan that is administered by the financial aid office of a two-year or four-year college at which you, or a qualified dependent, were enrolled as an under­ graduate student. Additionally, the loan must have been secured through a state student loan pro­ gram, a federal student loan program, or a com­ mercial lender, and must have been spent solely for the purposes of paying tuition and other ex­ penses directly related to the school enrollment. Enter the amount of such interest paid in Sched­ ule Y, line 12. This deduction is only allowed if not claiming the same expenses in line 10 of Schedule Y, Student Loan Interest Deduction. Line 13.

2025 Form 1 Instructions 23 such income from Massachusetts or its political subdivisions. For guidelines to determine which state’s pensions are exempt in Massachusetts, see TIR 95-9. Enter any deductible amount of such in­ come in line 13 of Schedule Y that was included in Form 1, line 4. Line 14. Claim of Right Deduction Taxpayers who have paid Massachusetts personal income taxes in a prior year on income attributed to them under a “claim of right” may deduct the amount of that income from their gross income if it later develops that they were not in fact enti­ tled to the income, and have repaid the amounts in question. The deduction is allowed in the year of repayment, provided that the repayment is not otherwise deductible in determining Massachu­ setts income taxable under MGL ch 62. Some examples in which the claim of right may be ap­ plied for are Stock under claim of ownership. Gains from sales of stock under a claim of ownership must be included, regardless of whether the taxpayer actually owned it Employment contracts. Amounts in settlement of employment contracts must be included notwith­ standing the prospect of eventual repayment to the employer of an amount equivalent to or greater than the amount received Dividends. Where a taxpayer receives a dividend that must be repaid in a later year (e.g., because it impaired corporate capital), the dividend must be included in the year of receipt; Corporate notes. Where a taxpayer receives a dis­ tribution with respect to holding of notes, the in­ come must be included regardless of whether it could be challenged by senior creditors Mistake in validity of claim. The claim of right doctrine applies where a taxpayer merely mistakes the validity of his claim Advanced insurance commissions; or Repayment of unemployment compensation and supplemental unemployment benefits in a sub­ sequent year. If you are entitled to claim this deduction, enter the amount claimed in Schedule Y, line 14. For more information, see TIR 06-4. Line 15. Commuter Deduction A deduction is allowed for certain amounts paid by an individual for tolls paid for through an E-Z Pass account or all MBTA fares, not just weekly or monthly transit commuter passes, and includes RTA fares, bikeshare memberships, bike pur­ chases (including e-bikes), bike improvements/ repair/storage, and fares on non-MBTA commuter boats that are owned, operated or contracted by a municipality or a public or quasi-public entity, agency or authority, not including amounts reim­ bursed or otherwise deductible. In the case of a single person or a married person filing a separate return or as head of household, this deduction applies only to the portion of such expended amount that exceeds $150, and the total amount deducted cannot exceed $750. In the case of a married couple filing a joint return, this deduc­ tion applies only to the portion of such amount ex­ pended by each individual that exceeds $150, and the total amount deducted cannot exceed $750 for each individual. Also, one spouse cannot transfer his or her excess deduction to the other spouse; separate worksheets must be completed to calcu­ late the deduction. See TIR 06-14 for additional information. The deduction is allowed where an individual pur­ chases an MBTA pass for a dependent who is claimed on that individual’s tax return, provided the dependent does not also claim the deduction. However, the total amount deducted cannot ex­ ceed $750 for each individual taxpayer who is fil­ ing a return. In the case of married taxpayers filing a joint return, the total amount deducted cannot exceed $750 per taxpayer; thus, the maximum de­ duction for a joint return is $1,500.

Deduction for Expenses of Human Organ Transplant An individual may deduct certain expenses and other costs incurred in the process of donating an organ for a human organ transplant to another in­ dividual. For purposes of this deduction, “human organ” shall mean all or part of human bone mar­ row, liver, pancreas, kidney, intestine or lung. In the case of an individual who donates an organ to another person for human organ transplantation, the individual may deduct the following expenses that are incurred by the individual and related to the individual’s organ donation: • Travel expenses; • Lodging expenses; and • Lost wages not to exceed $10,000. An individual who is a nonresident of Massachu­ setts for all or part of the taxable year is not eli­ gible to claim this deduction. If you are entitled to claim this deduction, enter the amount claimed in Schedule Y, line 16. See TIR 11-6 for further information. Line 17. Certain Gambling Losses Massachusetts allows a deduction from 5.0% income for losses from wagering transactions that were incurred in a calendar year at a Mas­ sachusetts gaming establishment licensed in ac­ cordance with MGL ch 23K or a racing meet ing licensee or simulcasting licensee, only to the ex­ tent of the gains from such transactions. See TIR 15-14 for more information. For tax years begin­ ning on or after January 1, 2024, this deduction also includes losses from sports wagers that were incurred through a Massachusetts sports wager­ ing operator licensed under MGL ch 23N. A taxpayer may claim a deduction for qualifying sports wagering and gambling losses incurred in the calendar year from the above Massachusetts sources only if the taxpayer had sports wagering or gambling winnings in the same calendar year from any such Massachusetts source. The de­ duction allowed for such losses may not exceed the amount of such winnings included in gross income for the calendar year. Because Massachusetts does not adopt the de- ductions under IRC § 165(d), the deduction for sports wagering and gambling losses set forth in MGL ch 62, § 3(B)(a)(18) is the only deduction for such losses al lowed a Massachusetts taxpayer, unless the sports wagering and gam bling activities of the taxpayer constitute a trade or business. Example For calendar year 2025, taxpayer, a Massachusetts resident, has: • Gambling winnings of $500 from Massachu­ setts state lottery; • Gambling winnings of $800 from a casino li­ censed under MGL ch 23K; • Gambling winnings of $1200 from a Las Vegas casino; • Sports wagering winnings of $500 from a sports wagering operator licensed under MGL ch 23N;

2025 Form 1 Instructions 24 • Sports wagering winnings of $600 from a sports wagering operator in Las Vegas; • Gambling losses of $1600 from a Las Vegas casino; • Gambling losses of $510 from Massachusetts Lottery scratch tickets; • Gambling losses of $1000 from a casino li­ censed under MGL ch 23K; • Sports wagering losses of $700 from a sports wagering operator licensed under MGL ch 23N; • Sports wagering losses of $200 from a sports wagering operator in Las Vegas. For Massachusetts income tax purposes, the tax- payer must include $500 of their Massachusetts state lottery win nings on Form 1, line 8b and the remaining $3,100 of their gambling and sports wagering winnings on Schedule X, line 3. The tax­ payer may claim a deduction for gambling losses from ca sinos licensed under ch 23K and for sports wagering losses from sports wagering op­ erators licensed under MGL ch 23N but only to the extent of winnings from casinos licensed under ch 23K and sports wagering operators licensed under MGL ch 23N. No deduction is available for the taxpayer’s gam bling and sports wagering losses from other sources. The taxpayer had win­ nings of $800 and losses of $1,000 from ca sinos licensed under ch 23K. The taxpayer had winnings of $500 and losses of $700 from sports wagering operators licensed under MGL ch 23N. Thus, the taxpayer may claim a deduction of $1300, the ex­ tent of aggregate winnings from qualifying Mas­ sachusetts sources. The remaining $400 of loss from casinos licensed under ch 23K and sports wagering operators licensed under MGL ch 23N may not be deducted. Gambling losses from the Massachusetts state lottery are not deductible. If you are entitled to claim this deduction, enter the qualified amount in Schedule Y, line 17. Line 18a. Prepaid Tuition or College Savings Plan Deduction A deduction is available for purchases of or con­ tributions made to an account in a pre-paid tuition program or a college savings program established by the Commonwealth. The deduction is capped at $1,000 for a single person, married filing sepa­ rate, or head of household and $2,000 for a mar­ ried couple filing a joint return. The deduction is subject to recapture in the taxable year or years in which distributions or refunds are made from the tuition or college savings account for any reason other than: • To pay qualified higher education expenses, as defined by IRC § 529(e)(3); or • The beneficiary’s death, disability or receipt of a scholarship. Enter the allowable amount on Schedule Y, Line 18a. For more information, see TIR 16-15. Line 18b. Student Loan Repayment Assistance Deduction A deduction is available for employer-provided student loan repayment assistance to the extent not already excluded from federal gross income. Employer-provided student loan repayment as­ sistance is the employer’s payment of an employ­ ee’s principal or interest on a qualified education loan, as defined in IRC § 221. Employees enter on line 18b the amount of such employer-pro­ vided student loan repayment assistance that ex­ ceeds $5,250. Schedule B Note: If showing a loss, be sure to mark over the X in the box to the left. Also, be sure to enclose with Form 1. Interest, Dividends and Certain Capital Gains and Losses You must file Massachusetts Schedule B if you had: • Dividend income; • Any interest income other than from Massachu­ setts banks taxed at 5.0%; • Short-term capital gains or losses; • Carryover short-term losses from prior years; • Long-term gains on collectibles and pre-1996 installment sales classified as capital gain income for Massachusetts purposes; • Gains or losses from the sale, exchange or in­ voluntary conversion of property used in a trade or business; • Net long-term capital gains and losses; or • Excess exemptions. Collectibles are defined as any capital asset that is a collectible within the meaning of IRC § 408(m), as amended and in effect for the taxable year, in­ cluding works of art, rugs, antiques, metals, gems, stamps, alcoholic beverages, certain coins, and any other items treated as collectibles for federal tax purposes. You need not file Massachusetts Schedule B if all interest income you had was from Massachusetts banks (reportable in Form 1, line 5), and you have no short-term capital gains or losses, long-term gains on collectibles and pre-1996 installment sales, gains or losses from the sale, exchange or involuntary conversion of property used in a trade or business, allowable deductions from your trade or business, carryover short-term losses from prior years, net long-term capital gains or losses, or excess exemptions. You must complete Massachusetts Schedule B if your interest or dividend income includes: div­ idends taxed directly to trusts or estates on a Mas­ sachusetts Fiduciary Return, Form 2; or distribu­ tions that are returns of capital. Part 1. Interest and Dividend Income Line 1. Total Interest Income Enter your total interest income from your U.S. Form 1040, lines 2a and 2b. Line 2.

Do not include exempt interest already included in Schedule B, line 1; • Taxable distributions from Massachusetts S corporations not reported in Schedule B, line 2. Distributions in excess of the Massachusetts ac­ cumulated adjustments account are dividends to the extent of the corporation’s Massachusetts ac­ cumulated earnings and profits. For more infor­ mation, see 830 CMR 62.17A.1; • Interest and dividends from a partnership, S corporation, grantor-type trust, or non-Massachu­ setts estate or trust from Massachusetts Sched­ ule E. Generally, portfolio interest and dividend income from partnerships and S corporations should already be included in Schedule B, line 1 and line 2 amounts; • Interest from a trade or business that is re­ ported on Massachusetts Schedule C; • Interest or dividends from a mutual fund, if such distributions are not included in Schedule B, line 1 or line 2. See Schedule B, line 6a; or • Global Intangible Low-Taxed Income (GILTI), to the extent included in income reported on federal Schedule 1. See Technical Information Release (TIR) 19-11.

Such entities in­ clude: those not doing business in Massachusetts; regulated investment companies or real estate in­ vestment trusts (as defined under IRC §§ 851 and 856 respectively); or holding companies (as de­ fined in MGL ch 62, § 8). Line 8. Allowable Deductions from Your Trade or Business Enter the appropriate amount from Massachu­ setts Schedule C-2 if you qualify for an excess trade or business deduction. Generally, taxpay­ ers may not use excess 5.0% deductions to offset other income. However, where the taxpayer files a Massachusetts Schedule C or Schedule E, Massa­ chusetts law allows such offsets if the following requirements are met: the excess 5.0% deduc­ tions must be adjusted gross income deductions allowed under MGL ch 62, § 2(d); and these ex­ cess deductions may only be used to offset other income which is effectively connected with the ac­ tive conduct of a trade or business or any other in­ come allowed under IRC, § 469(d)(1)(B) to offset losses from passive activities. Line 9. Subtotal Interest and Dividend Income Subtract line 8 from line 7. Part 2.

Long-Term Capital Gains and Losses Excluding Collectibles You must complete Massachusetts Schedule D if you had long-term gains or losses from the sale or exchange of capital assets or from similar transac­ tions which are granted capital gain or loss treat­ ment on your U.S. return, or if you had capital gain distributions. If you did not file U.S. Schedule D but are reporting capital gain distributions on U.S. Form 1040, line 7a, you must complete Massa­ chusetts Schedule D (see line 6 instructions). In­ clude gains from all property, wherever located. Long-term capital gains are gains on the sale or exchange of capital assets that have been held for more than one year on the date of the sale or ex­ change. Long-term capital losses are losses on the sale or exchange of capital assets that have been held for more than one year on the date of the sale or exchange. The law defines capital gain income as gain from the sale or exchange of a capital asset. The defini­ tion of capital asset includes: • An asset which is a capital asset under IRC § 1221; or • Property that is used in a trade or business within the meaning of IRC § 1231(b) without regard to the holding period as defined in said § 1231(b). Differences Significant differences between the U.S. and Mas­ sachusetts capital gain provisions are: • IRC § 1244 losses reported as ordinary losses on your U.S. return must be reported on Massa­ chusetts Schedule D; • If you made a federal election under § 311 of the Tax Relief Act of 1997 to recognize gain on the deemed sale of a capital asset held on Janu­ ary 1, 2001, Massachusetts does not follow the federal rules at § 311 for determining the basis of the asset. See TIR 02-3. If you sold a capital asset in 2025 for which you made a federal § 311 election, the Massachusetts initial basis will not be the federal basis. The Massachusetts initial basis will be determined as of the date the asset was first acquired; • Upon the sale of stock of an S corporation, the federal basis must be modified according to 830 CMR 62.17A.1; and • Massachusetts has adopted basis adjustment rules to take into account differences between Massachusetts and federal tax laws. For more information regarding basis adjustment rules, see TIR 88-7. Net ordinary losses that are itemized deductions on U.S. Schedule A are not allowable. Installment Sales If a sale was treated as an installment sale for U.S. income tax purposes, it may be treated the same way on your Massachusetts income tax return. Gains from pre-1996 installment sales are clas­ sified as either capital gains or ordinary income under the Massachusetts law in effect on the date the sale or exchange took place. Gains from pre-1996 installment sales that are classified as capital gains should be reported as 12% income on Massachusetts Schedule B. If the asset was held for more than one year when it was sold, the gain will be eligible for a 50% long- term deduction. Gains from pre-1996 installment sales that are classified as capital gains included on Massachusetts Schedule D, line 4 should be reported on Massachusetts Schedule D, line 12 (Long-term gains on collectibles and pre-1996 installment sales). The amount of such gain is then reported on Massachusetts Schedule B, Part 2, line 11. Gains from pre-1996 installment sales classified as ordinary income and that are included on Mas­ sachusetts Schedule D, line 4 should be reported on Massachusetts Schedule D, line 10 (Differ­ ences). The amount of such gain classified as or­ dinary income should then be reported on Form 1, line 9 (Other income) and included on Schedule X, line 4 and identified as 2025 gain from pre-1996 installment sale. Note: If you are reporting an installment sale oc­ curring on or after January 1, 2003, report those gains on Schedule D. If you are reporting capital gains on installment sales that occurred during

2025 Form 1 Instructions 28 January 1, 1996 through December 31, 2002, do not file Schedule D. Instead, you must file Sched­ ule D-IS, Installment Sales. Schedule D-IS can be obtained on DOR’s website at mass.gov/dor. Effective for sales on or after January 1, 2005, if you wish to report a sale on your Massachusetts return as an installment sale and the Massachu­ setts gain is $1 million or greater, you must apply in writing to DOR’s Installment Sales Unit. See TIR 04-28. The Commissioner of Revenue must ap­ prove your application to report the sale on the installment basis in Massachusetts before you file your return, and appropriate security must be posted. An explanatory statement must be en­ closed with each return for the life of the install­ ment sale. For further information contact the In­ stallment Sales Unit at (617) 887-6950. Exclusion of Gains from the Sale of Qualified Small Business (QSB) Stock or Reduced Capital Gains Tax Rate for Gains from the Sale of Stock in Certain Massachusetts-Based Start-Up Corporations Massachusetts excludes from gross income 100% of gain on sales or exchanges of qualified small business (QSB) stock held for more than 5 years to the same extent as allowed under IRC § 1202, as amended and in effect on January 1, 2024. The exclusion applies to gain on QSB stock acquired on or after September 27, 2010. See TIR 23-5 for more information. Note: Massachusetts does not conform to the expansion of the exclu­ sion made by Public Law 119-21. See Working Draft TIR: Massachusetts Conformity to Certain Provisions in Public Law No. 119-21. In addition, gains derived from the sale of invest­ ments in small businesses which do not qualify for the above exclusion may be eligible for a re­ duced tax rate of 3%. In order to qualify for the 3% rate, investments must have been made within five years of the corporation’s date of incorpora- tion and must be in stock that generally satisfies the definition of QSB stock under IRC § 1202 (c), other than the requirement that the stock be stock of a C corporation. In ad dition, the stock must be held for three years or more and the investments must be in a corpora tion which: • Is domiciled in Massachusetts; • Is incorporated on or after January 1, 2011; • Has less than $50 million in assets at the time of investment; and • Complies with applicable portions of the active business requirements of § 1202 of the IRC, i.e., §§ 1202 (e)(1), (e)(2), (e)(5), and (e)(6). Note: If you are reporting a sale of stock in a cer­ tain Massachusetts-based start-up corporation(s), do not file Schedule D. Instead, you must report that gain(s) on Schedule D-IS, Installment Sales or qualified small business stock gains. Sched­ ule D-IS can be obtained on DOR’s website at mass.gov/dor.

Allowable Deductions From Your Trade or Business Enter the appropriate amount from Massachu­ setts Schedule C-2 if you qualify for an excess trade or business deduction. Generally, taxpay­ ers may not use excess 5.0% deductions to offset other income. However, where the taxpayer files a Massachusetts Schedule C or Schedule E, Massa­ chusetts law allows such offsets if the following requirements are met: the excess 5.0% deduc­ tions must be adjusted gross income deductions allowed under MGL ch 62, § 2(d); and these ex­ cess deductions may only be used to offset other income which is effectively connected with the ac­ tive conduct of a trade or business or any other in­ come allowed under IRC, § 469(d)(1)(B) to offset losses from passive activities. Line 20. Excess Exemptions Enter in line 20 the amount from line 8 of the Schedule B, Line 36 and Schedule D, Line 20 Worksheet on page 11 (only if single, head of household or married filing joint return).

Available Losses for Carryover Enter the amount from Schedule D, line 17, only if it is a loss. Schedule C Note: If showing a loss, be sure to mark over the X in the box to the left. Also, be sure to enclose with Form 1. Substituting U.S. Schedule C U.S. Schedule C is not allowed as a substitute for Massachusetts Schedule C. Profit or Loss from Business or Profession Massachusetts Schedule C is provided to report income and deductions from each business or profession operated as a sole proprietorship. If your business deductions, excluding the Aban­ doned Building Renovation Deduction, exceed Schedule C income and any other income taxable at the 5.0% rate, such excess deductions may be subtracted from the other income that is effec­ tively connected with the active conduct of your trade or business and any other income allowed under IRC § 469(d)(1)(B) to offset losses from passive activities. To compute the excess trade or business deductions use Massachusetts Schedule C-2. This form is available by visiting mass.gov/ dor, or you may have one mailed to you by calling (617) 887-6367. Registration Information In the space provided, describe the business or professional activity that provided your principal source of income reported on line 1. If you owned more than one business, you must complete a separate Schedule C for each business. Give the general field or activity and the type of product or service. Employer Identification Number You need an Employer Identification number (EIN) only if you had a Keogh plan, were required to file an employment, excise, estate, trust, or alcohol, tobacco and firearms tax return or employ con­ tract labor. If you do not have an EIN, leave the line blank. Do not enter your Social Security number. Accounting Method If you filed a return on the accrual basis last year, your return for this year must be on the same basis. If a taxpayer requesting permission to change an accounting method for Massachusetts purposes is eligible for an automatic change of accounting method federally, and has correctly followed the most recently issued federal revenue procedure for requesting an automatic change, then the taxpayer should file his/her annual return using the new method and write at the top, “Au­ tomatic Change of Accounting Method — filed in compliance with DD 02-13.” The taxpayer should enclose a copy of U.S. Form 3115, together with any required statements. See DD 02-13 for fur­ ther information. See also, TIR 19-6: Impact of the Federal Tax Cuts and Jobs Act on a Taxpay­ er’s Overall Method of Accounting for Massachu­ setts Purposes. Material Participation Indicate if you materially participated in the op­ eration of this business during 2025. If you did not materially participate and have a loss from this business, see line 33 for further instructions. Started or Acquired this Business Indicate if you started or acquired this business in 2025. Also, fill in the oval if you are reopening or restarting this business after temporarily clos­ ing it, and you did not file a 2024 Schedule C for this business. Suspended Passive-Activity Loss Indicate if you have any suspended passive-activ­ ity losses that relate to the schedule being com­ pleted. See TIR 89-2 for further information and line 36 instructions.

2025 Form 1 Instructions 30 Statutory Employee If you received a Form W-2 and the “Statutory em­ ployee” box in item 13 of that form was checked, report your income and expenses related to that income on Schedule C. Enter your statutory em­ ployee income from box 1 of Form W-2 on line 1a of Schedule C and fill in the oval. Statutory em­ ployees include full-time life insurance agents, certain agent or commission drivers and travel­ ing salespersons and certain homeworkers. If you had both self-employment income and statutory employee income, do not combine these amounts on a single Schedule C. In this case, you must file separate Schedule Cs. Interest (other than from Massachusetts banks) and Dividend Income If you have interest (other than from Massachu­ setts banks) and dividend income reported on U.S. Schedule C, lines 1 and/or 6, fill in the oval and enter that amount in the space provided and in Massachusetts Schedule B, line 3. Do not include such amounts on Massachusetts Schedule C, lines 1 and/or 4. Examples of interest (other than from Massachusetts banks) and dividend income are interest received on loans, notes receivable or charge accounts that you accept in the ordinary course of business, and dividends on stocks re­ ceived in payment for goods and services. Capital gains from the sale or exchange of assets used in your business are not reported on Schedule C. Use U.S. Form 4797 and report the amount in Form 1, Schedule B and/or Schedule D. You must also exclude from Schedule C any income and expenses that pertain to activities for yourself as distinguished from those performed for your cus­ tomers. Such income must be reported by class of income in Schedules B and D. Personal expenses are not deductible. Line 1a. Gross Receipts or Sales In the boxes provided, enter gross receipts or sales from your business. Be sure to include on this line amounts you received in your trade or business as shown on Form 1099-MISC, Miscel­ laneous Income. If the nature of your business is such that you have gross or other income that is interest (other than from Massachusetts banks) and dividend income, exclude this income from lines 1 and 4 on Massachusetts Schedule C and include it in the space provided and in Schedule B, line 3. Note: Personal expenses are not deductible. To de­ termine if you need to file Schedule B, refer to the Schedule B instructions in this booklet. Line 4. Other Income If you received bartering income, you must report the fair market value of goods or services received in payment for your goods and services in line 4. Do not include interest income (other than from Massachusetts banks) and dividends here. Line 7. Bad Debts From Sales or Services Include debts and partial debts from sales or ser­ vices that were included in income and are defi­ nitely known to be worthless. If you later collect a debt that you deducted as a bad debt, include it as income in the year collected. Note: Cash method taxpayers cannot take a bad debt deduction unless the amount was previously included in income. Line 9. Commissions, Fees and Contract Labor Line 9a. Commissions and Fees Enter the total commissions and fees for the tax year. Do not include commissions or fees that are capitalized or deducted elsewhere on your return. Line 9b. Contract Labor Enter the total cost of contract labor for the tax year. Contract labor includes payments to persons you do not treat as employees (for example, inde­ pendent contractors) for services performed for your trade or business. Do not include contract labor deducted elsewhere on your return, such as contract labor included on line 15, 19, 25, or Schedule C-1, line 3. Also, do not include salaries and wages paid to your employees; instead, see Line 25, later. Line 11. Depreciation and § 179 Deduction (***) Massachusetts does not adopt the current max­ imum limits of the federal IRC § 179 expense deduction. The maximum § 179 expense allow­ ance is $1,250,000. The deduction phases out at $3,130,000. Massachusetts does not adopt the federal IRC § 168(n) special depreciation allowance. Taxpayers should follow the depreciation methods allowable under Massachusetts law. Line 14b. Other Interest Limitation on Business Interest Deduction § 163(j) (***) Taxpayers should take the Massachusetts limita­ tion into account when calculating the amount of interest entered on Line 14b. Massachusetts does not adopt the change to the federal adjusted tax­ able income definition in IRC § 163(j)(8) for the 2025 and 2026 tax years. For purposes of deter­ mining the allowable deduction taxpayers should not apply the federal limit. Instead, taxpayers should calculate their Massachusetts adjusted taxable income limit based on the rules in effect for the 2024 tax year. Line 17. Pension and Profit-Sharing Plans Enter your deduction for contributions to a pen­ sion, profit-sharing or annuity plan, or plans for the benefit of your employees. If the plan includes you as a self-employed person, do not include contributions made as an employer on your be­ half. See DD 08-3 for more information. Line 22. Travel Enter your expenses for lodging and transporta­ tion connected with overnight travel for business while away from your tax home. Generally, your tax home is your main place of business regard­ less of where you maintain your family home. You cannot deduct expenses paid or incurred in con­ nection with employment away from home if that period of employment exceeds one year. Spouse’s and other family members’ travel expenses are generally disallowed as a business deduction. Do not include expenses for meals and entertain­ ment on this line. Line 23. Deductible Meals Your deductible business meal expenses are a per­ centage of your actual business meal expenses. Include meals while traveling away from home for business. Instead of the actual cost of your meals while traveling away from home, you may use the standard meal allowance. Business meal expenses are deductible only if they are: • Directly related to or associated with the con- duct of your trade or business; • Not lavish or extravagant; and • Incurred while you or your employee is present at the meal. Generally, you may deduct only 50% of your busi­ ness meal expenses, including meals incurred while traveling away from home on busi ness. Business meals are 100% deductible if: • The meals and incidentals are furnished or re­ imbursed to an em ployee if you properly treat the expense as wages subject to withholding; and • The meals and incidentals are provided to a nonemployee to the extent the expenses are in­ cludible in the gross income of that person and reported on Form 1099-NEC. For individuals subject to the Department of Trans­ portation (DOT) hours of service limits, the per­ centage is 80% of business meals consumed during, or incident to, any period of duty for which those limits are in effect. Daycare providers can deduct 100% of the actual cost of food consumed by daycare recipients. Providers who qualify as family daycare provid­ ers may use the standard meal and snack rates to compute their deductible meals and snacks. Figure how much of your business meal expenses are subject to limitations, add that amount to your fully deductible meals amount and enter the re sult in line 23 of Massachusetts Schedule C.

Other Expenses Domestic Research and Experimental Expense Deduction (***) Massachusetts does not adopt the IRC § 174A domestic research and experimental expense de­ duction. For Massachusetts purposes, all research and experimental costs must be capitalized and recovered through amortization deductions. If a taxpayer includes expenses deducted under IRC § 174A on the U.S. Form 1040, Schedule C, Line 27b, the taxpayer should adjust Line 26 by sub­ tracting the amount of the federal domestic re­ search and experimental expense deduction from the cumulative amount of other expenses on Line 26. If this results in the amount on Line 26 being zero the taxpayer should report zero on Line 26. If this results in the amount on Line 26 being a negative number the taxpayer should report zero on Line 26 and add the remaining amount of the immediate domestic research and experimental expenses to Schedule X on line 4: Fees and Other 5.0% income. Ordinary and Necessary Business Expense De­ ductions Available for Licensed Massachusetts Marijuana Businesses IRC § 280E prohibits marijuana businesses from deducting business expenses and claiming tax credits for federal tax purposes. Effective for tax­ able years beginning on or after January 1, 2022, Massachusetts decoupled from the IRC § 280E deduction disallowance with respect to licensed marijuana businesses only. As a result, for Massa­ chusetts tax purposes, a licensed Massachusetts marijuana business can deduct ordinary and nec­ essary business expenses that would otherwise be disallowed under IRC § 280E. These ordinary and necessary trade or business expenses should be included on Schedule C, line 26 “Other expenses.” Line 30. Abandoned Building Renovation Deduction Massachusetts allows businesses to deduct 10% of the costs incurred in renovating certain build­ ings located in an Economic Opportunity Area (EOA). The buildings must be designated as aban­ doned by the Economic Assistance Coordinating Council. The renovation deduction may be taken in addition to any other deduction for which the ren­ ovation costs may qualify. For more information, contact the Massachusetts Office of Business De­ velopment by calling (617) 973-8600. In line 30 enter 10% of the costs of renovating a qualifying abandoned building. Line 31.

Senior citizens in Massachusetts may be eligible to claim a refundable credit on their state income taxes for the real estate taxes they paid on the Massachusetts residential property they own or rent and which they occupy as their principal resi­ dence. The maximum credit allowed is $2,820 for the tax year beginning January 1, 2025. See TIR 25-7 for more information. Eligible taxpayers who own their property may claim a credit equal to the amount by which their property tax payments in tax year 2025 (exclud­ ing any exemptions and/or abatements), including water and sewer debt charges, exceed 10% of their total income for the same current tax year. Taxpay­ ers residing in communities that do not include water and sewer debt service in their property tax assessments may claim, in addition to their prop­ erty tax payments, 50% of the water and sewer use charges, including stormwater fees, actually paid during the tax year when figuring their credit. Renters may claim a credit in the amount by which 25% of their annual rental payment is more than 10% of their total income. If your principal residence is held in trust If your principal residence is owned by a grantor trust, and either you or your spouse is a trustee, then you would qualify as a homeowner. If your principal residence is owned by a grantor trust, and you or your spouse are not Trustees, then renter rules are applied when determining the allowable credit. For example, you're a former owner who creates a life estate and puts property into the trust for your children's benefit. Generally, if you're under the terms of the trust, you pay to the trust in lieu of rent, you may treat these payments the same as if they were rent and should follow the renter rules when filing for the credit. Renter rules also apply if the principal residence is owned by an irrevocable trust, regardless of whether you or your spouse is a trustee Who Is Eligible for the Credit? To be eligible for the credit for the 2025 tax year, a taxpayer must be 65 years of age or older before January 1, 2026, (for joint filers, it is sufficient if one taxpayer is 65 years of age or older), must own or rent residential property in Massachusetts and occupy the property as his or her principal

2025 Form 1 Instructions 32 residence, and must not be the dependent of an­ other taxpayer. The taxpayer’s total income can­ not exceed $75,000 for a single filer who is not the head of a household, $94,000 for a head of household, or $112,000 for taxpayers filing jointly. No credit is allowed for a married taxpayer unless a joint return is filed. Moreover, the assessed valu­ ation of the real estate cannot exceed $1,298,000. No credit is allowed if the taxpayer claims the sta­ tus of married filing separate, receives a federal or state rent subsidy, rents from a tax-exempt entity, or is the dependent of another taxpayer. Note: Make sure the over age 65 oval(s) is filled in on Form 1, line 2c. Is the Tax Credit Considered Income? Tax credits received by eligible taxpayers are not considered income for the purpose of obtaining eligibility or benefits under other means-tested as­ sistance programs including food, medical, hous­ ing, energy and educational assistance programs. How Does a Taxpayer Claim the Credit? Taxpayers who are eligible for the tax credit in the 2025 tax year can claim the credit by submitting a completed Schedule CB, Circuit Breaker Credit, with their 2025 state income tax return. Eligible taxpayers who do not normally file a state income tax return may obtain a refund by filing a return with Schedule CB. As with all claimed tax credits and deductions, the taxpayer must keep all perti­ nent records, receipts and other documentation supporting his or her claim for the credit. Line 1. Living Quarters Status During 2025 Be sure to fill in the appropriate oval. If you were a renter in 2025 and you received any federal and/or state subsidy, or you rent from a tax-exempt entity, you do not qualify for the Circuit Breaker Credit. Homeowners must fill in the appropriate oval to indicate if they owned a multi-use or multi-family property or if their land exceeds one acre. A tax­ payer who owns a principal residence with a land area in excess of one acre or a multi-use build­ ing or land area, for example, a storefront with an apartment above, may only claim the taxpayer’s proportional share of the real estate tax payments (Schedule CB, line 10), including water and sewer use charges (Schedule CB, line 13), which corre­ sponds to the portion of the residence used and occupied as principal residence. A taxpayer who owns a multiple family dwelling (a multi-family residence that includes the taxpayer’s personal residence), may only claim the taxpayer’s propor­ tional share of the taxes (Schedule CB, line 10) or sewer and water use charges (Schedule CB, line 13) paid. For example, where a condominium as­ sociation pays one sewer and water bill for multi­ ple owners, each owner may only claim the pro­ portional share of the use charges attributable to the taxpayer’s condominium (for example, the condominium owner’s percentage interest in the undivided interest of common areas and facilities). Line 2. Assessed Value of Principal Residence as of January 1, 2025 Enter the amount of the assessed value of your principal residence as of January 1, 2025. If you own a multi-family home, mixed-use property, or more than one acre of land, only the assessed value of your principal residence, together with the land that immediately surrounds and is associated with that residence, not to exceed one acre, should be used (see worksheet in Schedule CB instruc­ tions). If the assessed value is over $1,298,000, you do not qualify for the credit. Contact your local city or town’s assessors’ office if you have any questions in determining the amount of the assessed value of your principal residence as of January 1, 2025. Income Calculation Qualifying income for the Circuit Breaker Credit (Schedule CB, lines 3 through 9) is the taxpayer’s Massachusetts AGI as defined in MGL ch 62, § 2 increased by various amounts that may have been excluded or subtracted when originally calculating the taxpayer’s Massachusetts AGI, less certain ex­ emptions claimed by the taxpayer. Amounts added back to Massachusetts AGI in computing qualify­ ing income include income from Social Security, retirement, pension or annuities, cash public as­ sistance, tax-exempt interest and dividends, net capital losses, long-term capital losses, certain capital gains, income from a partnership or trust not otherwise included in the taxpayer’s Massa­ chusetts AGI, and gross receipts (for example, the return of capital or gifts) from any other source except the tax credit itself. The exemptions allowed which decrease the total income amount are those allowed for blindness, dependents and taxpayers who are at least age 65 by the end of the tax year. Line 4. Total Social Security Benefits Enter in line 4 the amount of Social Security ben­ efits received in 2025. Social Security benefits include retirement, disability, dependent, survi­ vorship and insurance. Medicare premiums with­ held from Social Security payments should not be excluded. Line 5. Pension, Annuities, IRA/Keogh Distributions Not Taxed on Your Massachusetts Tax Return Enter in line 5 the amount of pension, annuities, IRA/Keogh distributions not taxed on your Massa­ chusetts Form 1. See Form 1, line 4 instructions, Pension and Annuities, for a list of exempt items that must be included in Schedule CB, line 5 as part of total income for the purposes of calculating the Circuit Breaker Credit. Line 6. Miscellaneous Income Including Cash Public Assistance Enter the amount of miscellaneous income, in­ cluding cash public assistance, received during 2025. This includes but is not limited to food stamps and welfare payments, disability income, gifts, sick pay, worker’s compensation and return of capital. Line 9. Total Qualifying Income Total income is not the same as taxable income for purposes of the tax credit, a taxpayer’s total qualifying income includes taxable income as well as exempt income such as Social Security, Trea­ sury bills and public pensions. For a complete list of what constitutes total qualifying income to calculate your total income and determine if you qualify for the credit, please visit our website at mass.gov/dor.

Real Estate Taxes Paid in Calendar Year 2025 for Your Principal Residence Enter the amount of real estate taxes paid in cal­ endar year 2025. Be sure to include real estate tax payments made pursuant to the Community Preservation Act, the Cape Cod Open Space Land Acquisition Program and/or paid to a tax-levy­ ing district. If you own a multi-family home, mixed-use prop­ erty, or your principal residence has a land area in excess of one acre, see TIR 01-19 for information on how to prorate real estate taxes paid. If your property is in excess of one acre, please see the Schedule CB Line 10 Property in Excess of One Acre Real Estate Tax Calculation Worksheet in the Schedule CB instructions. Note: Real estate taxes paid in a calendar or tax­ able year generally reflect taxes assessed for two different fiscal years. If a community collects taxes quarterly, a taxpayer may have made four payments during a calendar year. These payments are billed as due on the following dates: February 1, May 1, August 1, and November 1. If a commu­ nity collects taxes semi-annually, a taxpayer may have made two payments during the calendar year. The first payment is billed as due on May 1 and the second as due on November 1, or 30 days after it is mailed, if the bill is mailed after October 1. If you own a multi-family home, mixed-use property, or your principle residence has a land area in ex­ cess of one acre, contact your local city or town’s collector’s office if you have any questions in de­ termining the amount of real estate taxes paid in calendar year 2025 for your principal residence.

2025 Form 1 Instructions 33 Line 11. Adjustments to Real Estate Taxes Paid Enter the amount from line 4 of the Adjustments to Real Estate Taxes Paid Worksheet for Schedule CB, line 11, on page 2 of Schedule CB. Adjust­ ments to real estate taxes paid include: • Abatements granted by local assessors or earned through the Senior Work Program (do not exclude this amount if it was already reflected on your tax bill and you did not pay it); • Exemptions granted by cities or towns to qual­ ifying veterans, surviving spouses, blind persons and the elderly (do not exclude this amount if it was already reflected on your tax bill and you did not pay it); • Interest charges assessed due to delinquent payments; and • Betterments or special assessments levied upon the property. Line 13. Water and Sewer Use Charges Paid in 2025 Contact your town official to determine if your community has elected to include water and sewer debt charges in the property tax assessment. Tax­ payers residing in communities that do not include water and sewer debt charges in the property tax assessments may include 50% of the actual water and sewer use charges, including stormwater fees, paid during the taxable year. If they have elected to include those charges in the property tax assessment, enter 0 in line 13. If they have not elected to include those charges, enter 50% of your actual water and sewer use charges paid in 2025 in line 13. If you own a multi-family home, mixed-use prop­ erty, or your principal residence has a land area in excess of one acre, see TIR 01-19 for information on how to prorate water and sewer use charges. Line 18. Rent Paid for Your Principal Residence in 2025 Enter in line 18a the total amount of rent paid for your principal Massachusetts residence in 2025. Divide that amount by 4 (25%) and enter the result in line 18. In the space provided, be sure to enter your landlord’s name and address.

Schedule CMS Be sure to enclose with Form 1. Credit Manager Schedule You must complete Schedule CMS to claim most credits available for use in the current taxable year (the Child and Family, Earned Income, Limited In­ come and Circuit Breaker Tax credits are claimed directly on the tax return). Credits may be used to offset a tax due, may be passed or shared with another person or entity, or, in some cases credits may be fully or partially refundable. For each credit claimed on a Schedule CMS, report the amount of the credit available for use and the amount of credit claimed to reduce tax for the cur­ rent taxable year. For pass-through entities, report the amount of credit distributed to partners/share­ holders/beneficiaries in the credit shared column. Taxpayers also report the amount of a refundable credit they are using to request a refund of tax. See the Credit Manager Schedule Instructions for more information on how to complete the Sched­ ule CMS and claim the credits. Credits reported on the Schedule CMS are gen­ erally identified either by a certificate number as- signed by the issuing agency (which may be the Department of Revenue) or by the tax period end

2025 Form 1 Instructions 34 date in which the credit originated. If a credit has been assigned a certificate number, the certificate number must be included on the Schedule CMS. A taxpayer that does not include an assigned cer­ tificate number on the Schedule CMS will not be allowed the credit on the tax return and will have their tax liability adjusted by the Department of Revenue. Be sure to omit hyphens, spaces, deci­ mals and other special symbols when entering the certificate number. Also, enter the number from left to right. Likewise, a taxpayer that is required to complete a separate schedule to claim a credit must include the separate schedule with the taxpayer’s return filing. Failure to do so may result in the credit being disallowed. If, by operation of MGL ch 63, § 32C or another provision of law, a credit normally identified by tax period end date is eligible for indefinite carryover, the credit should be reported as “non-expiring” and identification of the tax period of origin is not necessary. Overview of Schedule CMS The following is a brief overview of the Schedule CMS sections and where certain credits should be reported. If a taxpayer is using a credit to reduce a taxpayer’s current year tax liability, whether it is a non-refundable credit or a refundable credit, the credit should be reported in Section 1 or 3 of the Schedule CMS. Only a refundable credit that the taxpayer is seeking a refund for should be re­ ported in either Section 2 or 4 of the Schedule CMS. Generally, a credit should only be reported in one section on the Schedule CMS unless a por­ tion of it is being used to offset a tax and a portion is being refunded. Section 1. Non-Refundable Credits Section 1 is for reporting credits the taxpayer is using (i) to offset or reduce the taxpayer’s total tax due (ii) to pass to any partner, shareholder or beneficiary of the taxpayer or (iii) to share with taxpayer affiliates. The Brownfields Credit, Film Incentive Credit, or Medical Device Credit should always be included in Section 1, unless the tax­ payer is requesting a refund of the Film Incentive Credit. However, a taxpayer that received a credit on a Massachusetts K-1 schedule from a pass- through entity or a credit transfer should report such credit in Section 3 or 4, as applicable. Section 2. Refundable Credits Section 2 is for reporting refundable credits the taxpayer is using to request a refund. The Film In­ centive Credit should always be included in Sec­ tion 2 to the extent that the taxpayer is requesting a refund. However, a taxpayer that received a re­ fundable credit on a Massachusetts K-1 from a pass-through entity or a credit transfer should re­ port such credit in Section 4, to the extent that the taxpayer is requesting a refund. For each refund­ able credit, report the amount of the credit avail­ able after taking into consideration any amount of the credits that may have been taken to offset a tax or shared as reported in Section 1 of this sched­ ule. Enter the amount by which the available credit balance is being reduced and the amount to be treated as a refundable credit, which may be ei­ ther 90% or 100% of the reduction. See TIR 13-6, Example 3, for an illustration. Section 3. Non-Refundable Credits Received from Massachusetts K-1 Schedules Section 3 is for reporting credits the taxpayer re­ ceived on a Massachusetts K-1 schedule (SK-1, 2K-1 or 3K-1) that the taxpayer is using (i) to offset or reduce the taxpayer’s total tax due (ii) to pass to any partner, shareholder or beneficiary of the taxpayer or (iii) to share with taxpayer af­ filiates. The Brownfields Credit, Film Incentive Credit, or Medical Device Credit should never be included in Section 3. Note: You do not report the Brownfields Credit, Film Incentive Credit, and Medical Device Credit in this section because these credits are issued new certificate numbers from the Department of Rev­ enue when they are received from a pass-through entity or a credit transfer. These credits should al­ ways be reported in Section 1, unless the taxpayer is requesting a refund of the Film Incentive Credit. Section 4. Refundable Credits Received from Massachusetts K-1 Schedules Section 4 is for reporting credits the taxpayer re­ ceived on a Massachusetts K-1 schedule (SK-1, 2K-1 or 3K-1) and that the taxpayer is using to re­ quest a refund. The Film Incentive Credit should never be included in Section 4. For each refund­ able credit, report the amount of the credit avail­ able after taking into consideration any amount of the credits that may have been used to offset a tax or shared as reported in Section 3 of this schedule. Enter the amount by which the available credit balance is being reduced and the amount to be treated as a refundable credit, which may be ei­ ther 90% or 100% of the reduction. See TIR 13-6, Example 3, for an illustration. FLMCRD 0000000011 $10,000 $10,000 $9,000 CNSLND 1110000000 $1,000 $1,000 $1,000 2a. Credit type 2b. Period end date (mm/dd/yyyy) 2c.

In Example 2, the taxpayer is an individual filing a return for the taxable year ending December 31, 2025 and has an available Septic Credit of $18,000 in the current year. The individual taxpayer must also enclose a Schedule SC. The individual should file Part 1 of the Schedule CMS to reflect a claimed credit of $4,000 (Schedule SC, line 13).

2025 Form 1 Instructions 35 Note: You do not report the refundable Film Incen­ tive Credit in this section because these credits are issued new certificate numbers from the Depart­ ment of Revenue when they are received from a pass-through entity or a credit transfer. If the tax­ payer is requesting a refund of the Film Incentive Credit, it should be reported in Section 2. Credit Table The Credit Table located at the end of these instruc­ tions lists all of the Massachusetts credit types with their respective attributes. Credits that may be available to a taxpayer subject to tax under MGL ch 62 must be claimed on Schedule CMS. The tax­ payer should refer to this table for guidance when completing Schedule CMS.

Massachusetts Department of Revenue PO Box 7011 Boston, MA 02204 PRSRT STD U.S. POSTAGE PAID COMMONWEALTH OF MASSACHUSETTS A Special Message from Revenue Commissioner Geoffrey E. Snyder I hope you find this Form 1 booklet helpful in preparing your taxes. When you are ready to file, I encourage you to consider e-filing in- stead of submitting a paper return. There are several benefits to e-filing your tax return, including using approved tax software and hiring a tax preparer. Here are some advantages of e-filing: • You will receive a faster refund compared to a return filed on paper. • Automatic corrections provide a more accurate return. • Enhanced security features protect your e-filed tax return. • If you owe taxes, you can set up an online payment plan and choose a payment date, saving you a trip to the post office. Additionally, free e-filing options are available for qualifying taxpayers at mass.gov/efile. Last year, nearly 95% of Massachusetts taxpayers chose to e-file. This tax season, I hope that e-filing becomes your first choice. Sincerely, Commissioner Geoffrey E. Snyder 75M 12/25 2026E02PRINTOFF48006 partially printed on recycled paper mass.gov/efile
