Department of Revenue Commonwealth of Massachusetts Mass.gov/eFile Before using paper, consider Form 1 2023 Massachusetts Resident Income Tax Fast — Filing electronically, rather than on paper, can mean much faster processing of your refund and money in your account sooner. Accurate — Generally, there are fewer errors with electronic filings than paper forms. Online programs make it easy to ensure that you don’t miss anything important. Ecofriendly — A great majority of Massachusetts taxpayers file electronically. Help us to continue reducing our carbon footprint.

Give e-file a try this year! C’mon, admit it — filing paper tax returns is no fun! So forget about longer refund wait times and calculation mistakes. E-file this year! There are three easy and convenient ways to do it. File Electronically for Free Many Massachusetts taxpayers qualify to file both federal and state returns for free, en hanc ing fraud protection and cutting down on identity theft. Massachusetts joined the Free File Alliance, a nonprofit partnership between tax preparation companies, the IRS and the states to increase opportunities for taxpayers to e-file their tax returns for free. Check out the free filing options available to taxpayers at mass.gov/efile. You may also be able to file your tax return online through DOR's MassTaxConnect. You qualify for this option if you were a Massachusetts resident for the entire 2023 tax year, previously filed a Massachusetts return, and the forms you file are supported by the program. Commercial Tax Preparation Software You can also e-file using commercial tax filing products. Visit our website for a complete listing of approved products. Although some of these products offer a paper filing op tion, you may only use that option if it incorporates a 2D barcode in the right-hand corner of all pages. If you have a 2D printing issue, be sure to contact the software manufacturer for instructions before filing to avoid having your return rejected. Also, be sure to use the correct 2D barcode mailing address: PO Box 7000 for refunds/no payments or PO Box 7003 for payments. See DOR’s online tax form instructions for more in formation. Tax Preparers The majority of paid tax preparers recognize that their clients don’t want mistakes, delays, or longer refund times so they offer e-filing for their customers. Moreover, Massachusetts law requires any preparer who completes more than 10 Massachusetts income tax returns to e-file (TIR 11-13 has a specific taxpayer opt-out provision to this law). Preparers who do file paper returns for their clients have specific requirements they must meet to avoid paying penalties and fines. You’ll find a list of preparers on the DOR website. You may qualify for assistance with preparing your tax returns. Check out options at mass.gov/taxassistance. 1 2 3 mass.gov/efile New! Fillable PDFs A popular filing option among taxpayers over the years is the option to file using fillable PDFs. This year, Massachusetts will be bringing that option to you. With fillable PDFs, you can directly enter your tax information and upon completion, print and send it to DOR. For more information, see mass.gov/dor/incomeforms.

Major 2023 Tax 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 17, 2024. April 15, 2024, when returns and payments would nor- mally be due, is Pa triots' Day, a legal holiday in the Commonwealth, and April 16, 2024 is Eman­ cipation Day, a legal holiday in Washington, D.C. As a result, returns, payments made with returns, and estimated payments otherwise due on April 15, 2024, will be treated as timely if they are filed and/or paid on or before April 17, 2024. 2023 Personal Income Tax Rates The tax rate on most classes of tax able income is 5%. The tax rate on long-term gains from the sale or exchange of collectibles is 12% (subject to a 50% deduction). For tax years beginning on or after January 1, 2023, the tax rate on short- term gains from the sale or exchange of capital assets is 8.5%. 4% Surtax on Taxable Income Over $1 Million For tax years beginning on or after January 1, 2023, MGL ch 62 taxpayers must pay an addi­ tional 4% (“4% surtax”) on taxable income over a certain threshold. In 2023, this threshold is $1,000,000. The threshold is subject to an annual inflation adjustment. See Technical Information Release (TIR) 23-12 and the 4% Surtax FAQ for more information. 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 2023, 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 2023, which will be imposed through the individual’s personal income tax return, are set out in TIR 22-17 and are based on the monthly insurance premium for which an individual would have qualified through the Health Connector. Annual Update of 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. Effective for tax years be­ ginning on or after January 1, 2023, the statutory base amount has been doubled, resulting in an increase of the maximum credit to $2,590. 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 2023 must not exceed $1,025,000. For purposes of calculating the credit, total income and maxi­ mum credit thresholds are adjusted annually for inflation. For tax year 2023, an eligible taxpayer’s total income cannot exceed $69,000 in the case of a single filer who is not a head of household filer; $86,000 in the case of a head of household filer; and $103,000 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 prin­ cipal residence. Employer-Provided Parking, Transit Pass, and Commuter Highway Vehicle Benefits Exclusion Amounts Massachusetts conforms to Internal Revenue Code (“IRC”) § 132(f) as amended and in effect on January 1, 2022. IRC § 132(f) excludes from an employee’s gross income (subject to a monthly maximum adjusted annually for inflation) employ­ er-provided parking, transit pass, and commuter highway vehicle transportation benefits. The IRS has determined the 2023 monthly exclusion amounts to be $300 for employer-provided park­ ing and $300 for combined transit pass and com­ muter highway vehicle transportation benefits. See TIR 22-15 for more information. Reinstatement of the Personal Income Tax Deduction for Charitable Contributions For tax years beginning on or after January 1, 2023, a deduction for charitable contributions is available for MGL ch 62 taxpayers. This deduction had been suspended since the 2002 tax year. See Schedule Y instructions for more details. Increase to the Rental Deduction The rental deduction is equal to half of the rent paid for a principal residence located in Massa­ chusetts in a taxable year. The rental deduction cannot exceed a maximum amount. For tax years beginning on or after January 1, 2023, the max­ imum amount of the rental deduction is $4,000 ($2,000 if married filing a separate return). Previ­ ously, the maximum amount of the rental deduc­ tion was $3,000 ($1,500 if married filing a sepa­ rate return). Expansion of the Commuter Deduction For tax years beginning on or after January 1, 2023, the commuter deduction has been ex­ panded to include expenses incurred for all Mas­ sachusetts Bay Transit Authority (“MBTA”) fares, Massachusetts regional transit authority fares, fares for any commuter boat owned, operated, or contracted by a municipality, public or quasi-pub­ lic entity, agency, or authority, bikeshare mem­ berships, and the cost of bicycles purchased for commuting (including electric bicycles and bicy­ cle improvements, repairs, and storage). Previ­ ously, the deduction was available only for tolls paid for through a Fast Lane account or for weekly or monthly MBTA transit commuter passes for transit, bus, commuter rail, or commuter boat. Deduction for employer-provided student loan payment assistance For tax years beginning on or after January 1, 2023, employees may deduct the amount of em­ ployer-provided “student loan payment assis­ tance” received during the taxable year that has not already been excluded from their gross in­ come under IRC § 127. Employer-provided “stu­ dent loan payment assistance” is an employer’s payment of an employee’s principal or interest on a qualified education loan, as defined in IRC § 221. Up to $5,250 of these employer payments made in a calendar year beginning before Janu­ ary 1, 2026 are excluded from federal and, there­ fore, Massachusetts gross income. See TIR 23-5 for more information. As a result, if an employer made payments on an employee’s principal or in­ terest on a qualified education loan during the tax­ able year, the employee may deduct the amount of such “student loan payment assistance” that exceeds $5,250. Employees may not claim any other deduction, such as for student loan inter­ est, for employer-provided “student loan payment assistance.” Wind Power Incentive Jobs Credit For tax years beginning on or after January 1, 2023, and until tax years ending on or before December 31, 2032, a business subject to tax under MGL ch 62 may, to the extent authorized by the offshore wind tax incentive program es­ tablished in MGL ch 23J, § 8A(d), be allowed a refundable credit in an amount determined by the Massachusetts Clean Energy Technology Center, in consultation with the Department of Revenue. A business taking this credit must commit to the creation of a minimum of 50 net new perma­ 2023 Form 1 Instructions 3

nent full-time employees in Massachusetts. See TIR 23-6 and MGL ch 62, § 6(bb) for additional information. Wind Power Incentive Investment Credit For tax years beginning on or after January 1, 2023, and until tax years ending on or before De­ cember 31, 2032, a business subject to tax under MGL ch 62 may, to the extent authorized by the offshore wind tax incentive program established in MGL ch 23J, § 8A(d), be allowed a refundable credit in an amount, as determined by the Massa­ chusetts Clean Energy Technology Center, of up to 50 percent of its total capital investment in an offshore wind facility. See TIR 23-6 and MGL ch 62, § 6(cc) for additional information. National Guard Hiring Tax Credit For tax years beginning on or after January 1, 2023, a business subject to tax under MGL ch 62 that employs not more than 100 employees may be allowed a credit equal to $2,000 for each mem­ ber of the Massachusetts National Guard hired by the business after July 1, 2022. See TIR 23-6 and MGL ch 62, § 6(aa)for additional information. Disability Hire Tax Credit For tax years beginning on or after January 1, 2023, businesses subject to tax under MGL ch 62 that hire employees after July 1, 2021 with a disability who live and work in Massachusetts may be eligible for a credit. The credit is equal to the lesser of $5,000 or 30% of the wages paid to a qualified employee in the first year of em­ ployment, and the lesser of $2,000 or 30% of the wages paid to a qualified employee in each subsequent year of employment. For additional information, see 830 CMR 63.38JJ.1: Disability Employment Tax Credit. Child and Family Tax Credit Starting with tax years beginning on or after Janu­ ary 1, 2023, individuals subject to tax under MGL ch 62 may claim a refundable, non-transferable child and family tax credit (“CFTC”) if they main­ tain a household as provided under IRC § 21. The household must include an individual who is (1) under the age of 13 and who qualifies for exemp­ tion as a dependent under IRC § 151; (2) a qual­ ifying individual pursuant to IRC § 21, which in­ cludes a dependent, as defined in IRC § 152, or the taxpayer’s spouse, who is physically or men­ tally incapable of taking care of himself or herself and principally lives with the taxpayer; or (3) a dependent under IRC § 152 who is age 65 or over or disabled. For the tax year beginning on or after January 1, 2023, the amount of the CFTC is equal to $310 for each such individual. The CFTC will be increased to $440 for each such individual be­ ginning with tax years beginning on or after Jan­ uary 1, 2024. The CFTC replaces the Dependent Care Tax Credit and the Household Dependent Tax Credit, which were repealed for tax years beginning on or after January 1, 2023. Increase in the Massachusetts Earned Income Tax Credit Effective for tax years beginning on or after Jan­ uary 1, 2023, the amount of the Massachusetts earned income tax credit an individual may claim is 40% of the computed federal credit. The credit cannot be claimed by married taxpayers that file separate Massachusetts personal income tax returns. With respect to a taxpayer who is a non-resident for part of the taxable year, the credit must be multiplied by a fraction, the numerator of which is the number of days in the taxable year the taxpayer resided in the Commonwealth and the denominator of which is the total num­ ber of days in the taxable year. A taxpayer who is a non-resident for the entire taxable year cannot claim the credit. Increase to the Lead Paint Tax Credit Effective for tax years beginning on or after Jan­ uary 1, 2023, the maximum amount of the Lead Paint Tax Credit has been increased from $1,500 for each residential unit in which lead paint was deleaded to $3,000. In addition, the maximum amount of the credit for residential units in which lead paint was partially covered or removed has been increased from $500 to $1,000. Increase to the Septic Credit Effective for tax years beginning on or after Jan­ uary 1, 2023, the maximum amount of the Sep­ tic Credit taxpayers may claim per taxable year has been increased from $1,500 to $4,000. Ex­ cess amounts may be claimed in the subsequent five tax years. The maximum total credit amount that can be claimed with respect to a particular project is increased from $6,000 to $18,000. In addition, the percentage of allowable septic sys­ tem expenditures used to calculate the credit in­ creased from 40% to 60%. If you claimed a Septic Credit before January 1, 2023, and will claim ex­ cess amounts in the 2023 and later tax years, the amount of the credit continues to be governed by the prior limitations: the maximum annual credit amount is $1,500; the maximum total credit amount is $6,000; and the percentage of allow­ able septic system expenditures used to calculate the credit is 40%. Extension of Brownfields Tax Credit The brownfields tax credit, previously scheduled to expire on August 5, 2023, has been extended for five additional years. To qualify for a brown­ fields tax credit, a taxpayer must commence the environmental response action on or before Au­ gust 5, 2028, and incur net response and removal costs before January 1, 2029. See TIR 23-12 for more information. Conformity to the Internal Revenue Code (IRC) As a general rule, Massachusetts does not con­ form to any personal income tax law changes to the IRC made after January 1, 2022. See TIR 23-5 for more information. However, certain specific Massachusetts personal income tax provisions, as set forth in MGL ch 62, § 1(c), automatically conform to the IRC currently in effect. The pro­ visions of the IRC that Massachusetts conforms to on a current basis include those provisions 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. 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. 2023 Form 1 Instructions 4

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; ◗ 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 Resi­ dency 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 not allowed unless both spouses were Massachusetts residents for the same por­ tion of 2023. If your spouse died during 2023, 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 $310 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 2023 Form 1 Instructions 5

◗ 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 $2,590. 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. 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 2024? 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 taxes. Estimated tax payments can be made on­ line by using MassTaxConnect at www.mass.gov/ masstaxconnect or by filing Massachusetts Form 1-ES. See line 40 instructions and TIR 04-25 for more information. When to File Your Return Your 2023 Massachusetts Form 1 is due on or be- fore April 17, 2024. See "Filing Due Dates" above. 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 2023 Form 1 Instructions 6

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 Part­ nership 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. 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 2023 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. ◗ Lines 39 and 40 – Be sure to differentiate any overpayment from 2022 as a credit carry forward on line 39 and do not list it as 2023 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 $509.44 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 sub­ mit Schedule HC showing the FEIN and subscriber number, member ID or Group number from in­ surance 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 Be sure to fill in the appropriate oval if a taxpayer died during the taxable year. For further informa­ tion, refer to the section How Do I File a Dece­ dent’s Return? Under Age 18 If you are under age 18 as of January 1, 2024, be sure to fill in the oval(s). 2023 Form 1 Instructions 7

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. 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, § IV) applies to taxpayers that take an inconsis­ tent 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 taxpayers with foreign corporation income (in­ cluding Global Intangible Low-Taxed Income (GILTI)) must complete Schedule FCI. Detailed in­ structions for completing Schedule FCI are avail­ able on DOR’s website. See Schedule FCI and Instructions. Digital Assets Fill in the oval if at any time during 2023 you re­ ceived (as a reward, award, or payment for prop­ erty or services) a digital asset, or sold, exchanged, gifted, or otherwise disposed of a digital asset (or a financial interest in a digital asset). Digital assets include non-fungible tokens (NFTs) and virtual cur­ rencies, such as cryptocurrencies 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 living in the same household, each spouse must com­ bine their income figures from their separate U.S. returns when completing this section. If you did not have a requirement to file a U.S. return, 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 11). If married filing sep­ arately and living in the same household, each spouse must combine their income figures from their separate U.S. returns when completing this section. If you did not have a requirement to file a U.S. return, 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. Single Fill in the Single oval if you were single as of De­ cember 31, 2023. 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 2023; or ◗ You were legally separated under a final judg­ ment of the probate court. Note that 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, 2023. 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 2023. 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, 2023, 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 2023 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. 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 status 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. 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 ◗ 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 consistently throughout the return. 2023 Form 1 Instructions 8

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 2024 You are allowed an additional $700 exemption if you were age 65 or over before January 1, 2024. 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 2023 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 2023, you are eligible for an exemp­ tion of the total amount of the fees paid during the year. Fees paid during 2023 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 2023 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: Following are instances that require an ad­ justment 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. 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 gener­ ally enter in line 4 the taxable amount reported on your U.S. Form 1040, line 5b. In some cases, how­ ever, Massachusetts law requires an adjustment 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 that have been previously taxed. Subtract from such income (as reported on your U.S. Form 1040, line 5a) the amount of your contributions which was previously taxed by Mas­ sachusetts until the total of your taxed contribu­ tions is received. If your pension falls into this cat­ egory, enter the adjusted amount in line 4. If you are receiving 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 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- 2023 Form 1 Instructions 9

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 5a the total amount of interest re­ ceived or credited to deposit accounts (term and time deposits, including certificates of deposit, savings accounts, savings shares, and NOW ac­ counts) in Massachusetts banks. Then, enter your exemption amount in line 5b (if married filing jointly, enter $200; otherwise, enter $100). Sub­ tract line 5b from 5a and enter the result in line 5, but not less than 0. Note: This exemption amount does not apply to your U.S. tax return. Do not subtract interest forfeited or penalties charged to you for early savings withdrawal. You will be allowed to deduct these amounts on Sched­ ule 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. Note: Following the Code Update, you may not de­ duct an excess business loss (EBL) for tax year 2023. 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. Farm Income or Loss If you operate a farm as an individual or coop­ erative, enter in line 6b the amount of income or loss from operating a farm from U.S. Schedule F, Profit or Loss from Farming, line 34. Enclose a copy of U.S. Schedule F. Complete a pro forma U.S. Schedule F to report Massachusetts differ­ ences, such as bonus depreciation. Line 7. 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 2023 income tax return, you may file your Schedule(s) E on paper. Visit our website at mass.gov/dor to download a paper copy of the 2023 Schedule(s) E, E-1, E-2, E-3 (and instruc­ tions) to file with your income tax return. Line 8a. Unemployment Compensation If you received unemployment compensation, enter in line 8a the amount from U.S. Form 1040, Schedule 1, line 7. If you elected voluntary with­ holding of Massachusetts state income taxes on your unemployment compensation, be sure to in­ clude the amount of Massachusetts state income tax withheld, as reported on Form 1099-G, on Form 1, line 38b. Note: DOR routinely matches the amounts in line 8a with files from the Division of Unemployment Assistance. Line 8b. Massachusetts State Lottery Winnings Enter in line 8b all winnings from the Massachu­ setts state lottery. Do not enter less than 0. You may only deduct the price of your winning ticket. Lottery losses claimed as itemized deductions on U.S. Form 1040, Schedule A are not allowed on your Massachusetts return. Note: DOR routinely matches the amounts in line 8b with files from the Lottery Commission. Line 9. Other Income (from Schedule X) Taxable Alimony Received, Taxable IRA/ Keogh and Roth IRA Conversion Distribu­ tions, Other Gambling Winnings, Fees, Excess Business Loss Adjustment, and Other 5.0% Income and PFML taxable distributions. “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 pro­ cessing 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 (FICA), Medicare, Rail road, U.S. or Massachusetts Retirement Systems If you have paid into any of the retirement systems listed above during 2023, 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 2023 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 2023 Form 1 Instructions 10

amount of self-employment tax as reported on your U.S. Form 1040 to the amount of Social Se­ 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 2023 (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 2023 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. If line 18 exceeds line 17 and you received inter­ est income (other than interest from Massachu­ setts banks), dividends or capital gain income, complete the Schedule B, Line 36 and Schedule D, Line 20 Worksheet, if applicable. All others pro­ ceed to line 20. Schedule B, Line 36 and Schedule D, Line 20 Worksheet. Excess Exemptions from Interest and Dividend Income, 8.5% and 12% Income and Long-Term Capital Gain Income (Only if Single, Head of Household, or Married Filing Jointly) If your total exemptions in Form 1, line 18 are more than the amount of your 5 .0% income after deduc­ tions in Form 1, line 17, the excess may be applied against any interest and dividend income and in­ come taxed at 8 .5% or 12% . Any remaining excess amount may then be applied against any long-term capital gain income .

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 total credit that you calculate on the work­ sheet is the smaller of the amount of taxes due to other jurisdictions (net of certain adjustments) or the portion of your Massachusetts tax due on your gross income that is taxed in such other jurisdictions. Credit is not given for a property tax due to another jurisdiction on account of capital stock or property. This does not refer to a tax on gain or income from 2023 Form 1 Instructions 13

For residents that are subject to the 4% surtax and that paid tax in another jurisdiction, complete the online Schedule OJC worksheet(s). You must complete separate worksheets if you had 5.0% income and interest income (other than interest from Massachusetts banks), dividends or capital gain income taxed by another jurisdiction. If you use this worksheet to calculate a credit for interest income (other than interest from Massa­ chusetts banks), dividends or capital gain income, substitute interest income (other than interest from Massachusetts banks), dividends or capital gain income for 5.0% income in line 1 of the work­ sheet. You must also substitute Schedule B, line 7 (interest and dividend income) and Schedule B, line 13c (taxable 8.5% and 12% capital gains) or Schedule D, line 13, (gross long-term capital gains and losses), but not less than 0, for Form 1, line 10 in line 2 of the worksheet, and the total of Form 1, line 20 multiplied by 0.05 (tax on interest and divi­ dend income) and Form 1, line 23 (8.5% and 12% tax) or line 24 (tax on long-term capital gains) for Form 1, line 19 in line 4 of the worksheet. If completing multiple worksheets, the amount calculated as an Other Jurisdiction Credit on each worksheet should be combined for the total allow­ able Other Jurisdiction Credit. Online worksheets are available. See https://www.mass.gov/info-de­ tails/learn-about-the-income-tax-paid-to-another- jurisdiction-credit. ◗ When using the worksheet to calculate credit for interest income (other than interest from Massachusetts banks), dividends or capital gain income, enter in line 1 such income taxed in an­ other jurisdiction calculated as if it was earned in Massachusetts. ◗ If you choose to pay the optional 5.85% tax rate, substitute 0.0585 for 0.05 in line 4 of the worksheet.

Line 34. Massachusetts Use Tax Due On Internet, Mail Order and Other Out-of- State Purchases Made in 2023 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 03-01 for more information. No credit is allowed for a value-added tax (VAT) paid to an­ other 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 ◗ 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 Massa­ chusetts 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.

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.

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 MassTaxCon­ nect account. If you don’t have a MassTaxCon­ nect account, you can sign up at www.mass.gov/ masstaxconnect. You may request your employer to 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.

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 17, 2024, 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 $2,590 for the tax year beginning January 1, 2023. 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 $310 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 2023 Form 1 Instructions 16

payer; or (3) a dependent who is age 65 or over or disabled. Enter the number of qualified dependents in line 46a and multiply that amount by $310. 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. 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 2023 tax year, the income limit is set at $160,200 and the maxi­ mum PFML contribution amount for most individ­ uals is $509.44. For a self employed individual not subject to PFML withholding who opts into PFML, the maximum PFML contribution is $1,009.00. 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 2023 tax year, and the total amount of your combined Mas­ sachusetts W-2 wage income exceeded $160,200, you should complete the worksheet below to de­ termine if you have excess PFML withholding. The PFML law follows the unemployment stat­ ute, malegislature.gov/Laws/GeneralLaws/PartI/ TitleXXI/Chapter151A/Section1, 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 Se­ curity 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 eligi­ ble for a credit the total PFML contribution amount remitted on your behalf must exceed $509.44. 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 2023 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 calcu­ lated, see the Department of Family and Med­ ical Leave’s (DFML) regulation at 458 CMR 2.00, and DFML’s website at mass.gov/orgs/ department-of-family-and-medical-leave.

Refund Amount Line 52. Amount of Overpayment You Want Applied to Your 2024 Massachusetts Estimated Tax Enter the amount of your 2023 overpayment that you wish to apply to your 2024 Massachusetts es­ timated tax. Once an election is made to apply your overpayment to your 2024 estimated tax, it cannot be refunded after the due date of the return or ap­ plied to any additional tax you may owe for 2023, including any tax due on an amended return. The amount entered in this line can only be claimed as a credit on your 2024 Massachusetts return. Note: This amount cannot be changed on an amended return. 2023 Form 1 Instructions 17 continue on next page ...

Line 53. Refund Amount Subtract line 52 from line 51. Enter the result in line 53. 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 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 53 if you are requesting direct deposit. Failure to do so will result in your request for direct de­ posit being denied. Tax Due Line 54. Tax Due If line 37 is larger than line 50, subtract line 50 from line 37, and enter the result in line 54. 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 payment 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 2023 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 54. 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, 2024; ◗ You were a Massachusetts resident and were not liable for 2022 taxes (where the taxable year was 12 months); or ◗ The sum of your estimated payments and with­ holding equals or exceeds your 2022 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 54 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 2022 or 2023 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 54. 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 all state copies of your Forms W-2, W-2G, PWH-WA, 2G and any Forms 1099 which included Massachusetts withholding. Go to mass.gov/masstaxconnect for online pay­ ment options. If you need to mail your payment, make your check or money order payable to Com­ monwealth 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 2023 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 2023 Form 1 Instructions 18

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; ◗ 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 2024 tax return. This is April 15, 2025 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 mailing label on the back of the envelope that came with this booklet. If you do not have one, mail your orig­ inal 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 which were previously subject to Massachusetts 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 not considered previously taxed contributions and are fully taxable upon distribution.

Do not enter less than 0. You may only deduct the price of the winning ticket. Certain sports wagering and all gambling losses are now deductible under Massachusetts law. See Sched­ ule Y, line 17 and TIR 15-14 for more information. 2023 Form 1 Instructions 19

Note: Do not report Massachusetts state lottery winnings in Schedule X, line 3. Instead, report them on Form 1, line 8b. Line 4. Fees and Other 5.0% Income The following items should be reported on line 4 of Schedule X. Do not enter less than 0. Enclose addi­ tional statements if more space is needed. ◗ All fee income, such as payments for jury duty, election worker payments, director’s fees, com­ pensation received as executor or administrator of an estate, and commission income or tips not reported in line 3 of Form 1 are taxable. Also, re­ 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. ◗ 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 US 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. The following items should not be reported on your Massachusetts return: ◗ Any net operating loss reported as a negative amount on U.S. Form 1040, Schedule 1, line 9 cannot be entered on Schedule X. 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 2023, 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 $270,000 for single filers and $540,000 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 foward 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 5a or line 20 of this return or on a prior-year Massachusetts return, you may deduct the pen­ alty. This deduction is the same as the amount al­ lowable on U.S. Form 1040, Schedule 1, line 18. Enter this amount in line 2 of Schedule Y. Line 3. Deductible Alimony Paid Enter in Schedule Y, line 3 the total deductible ali­ mony paid to your former spouse as reported on U.S. Form 1040, Schedule 1, line 19a. Line 4.

Enter any excludible amount of income received while you were a firefighter or police officer inca­ pacitated in the line of duty in line 4 of Schedule Y that was included in Form 1, line 3, and fill in the appropriate oval. If you were a qualifying student or a taxpayer with income exempt under a United States tax treaty, enter any excludible amount of income received that was exempt under such tax treaty in line 4 of Schedule Y that was included in Form 1, line 3, and fill in the appropriate oval. Line 5. Moving Expenses for Members of the Armed Forces For tax years 2018 through 2025, for qualifying members of the Armed Forces, enter in Sched­ ule Y, line 5 the amount of moving expenses as reported on U.S. Form 1040, Schedule 1, line 14. Line 6. Medical Savings Account Enter in Schedule Y, line 6 the amount of the Med­ ical Savings Account deduction included in U.S. Form 1040, Schedule 1, line 23, “MSA.” Line 7. 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.

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.

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. Complete the Massachusetts AGI Worksheet and the Schedule Y, line 11 worksheet to see if you may qualify for this deduction. This deduction is only available to full year residents.

Line 12. Undergraduate Student Loan In­ terest 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. Deductible Amount of Qualified Contributory Pension Income from Another State or Political Subdivision Included in Form 1, Line 4 Massachusetts allows a deduction for contribu­ tory pension income received from another state or one of its political subdivisions that does not tax 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 2023 Form 1 Instructions 21

included, regardless of whether the taxpayer actu­ ally owned it; ◗ Employment contracts. Amounts in settle­ ment of employment contracts must be included not-withstanding the prospect of eventual repay­ ment to the employer of an amount equivalent to or greater than the amount received; ◗ Dividends. Where a taxpayer receives a divi­ dend that must be repaid in a later year (e.g., be­ cause it impaired corporate capital), the dividend must be included in the year of receipt; ◗ Corporate notes. Where a taxpayer receives a distribution with respect to holding of notes, the income 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 subsequent 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, 2023, 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 2023, 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 waging winnings of $500 from a sports wagering operator licensed under MGL ch 23N; ◗ Sports waging 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 waging losses of $700 from a sports wa­ gering operator licensed under MGL ch 23N; ◗ Sports waging losses of $200 from a sports wa­ gering 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 2023 Form 1 Instructions 22

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 Sav­ ings 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 D 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. 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 7, 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). For a detailed explanation of the law, see DOR’s Regulation on Capital Gains and Losses at 830 CMR 62.4.1. 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 2023 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, 2023 Form 1 Instructions 26

line 9 (Other income) and included on Schedule X, line 4 and identified as 2023 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 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, 2022, so long as the sale or exchange occurred on or after January 1, 2022. For both federal and Massachusetts purposes, this exclusion applies to gain on QSB stock acquired on or after September 27, 2010. See TIR 23-5 for more information. 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.

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.

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 adopts the current federal §179 rules for expensing certain depreciable business assets. The maximum § 179 expensing allowance is $1,160,000. 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 are food or beverages provided by a restaurant and paid or incurred after December 31, 2020, and before January 1, 2023; ◗ 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.

Other Expenses Ordinary and Necessary Business Expense De­ ductions Available for Licensed Massachu­ setts Marijuana Businesses IRC § 280E prohibits marijuana businesses from deducting expenses and claiming tax credits for federal tax purposes. Effective for taxable years beginning on or after January 1, 2023, Massachu­ setts decoupled from the IRC § 280E deduction disallowance with respect to licensed marijuana businesses only. As a result, for Massachusetts tax purposes, a licensed Massachusetts marijuana business can deduct ordinary and necessary busi­ ness expenses that would otherwise be disallowed under IRC § 280E. These ordinary and necessary trade or business expenses should be reported 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 $2,590 for the tax year beginning January 1, 2023. See TIR 23-11 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 2023 (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. For purposes of the tax credit, a taxpayer’s total income includes taxable income as well as exempt income such as Social Security, Treasury bills and public pensions. For a complete list of what con­ stitutes total income, see TIR 01-19. Who Is Eligible for the Credit? To be eligible for the credit for the 2023 tax year, a taxpayer must be 65 years of age or older before January 1, 2024, (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 residence, and must not be the dependent of an­ other taxpayer. The taxpayer’s total income can­ not exceed $69,000 for a single filer who is not the head of a household, $86,000 for a head of household, or $103,000 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 $1,025,000. 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. 2023 Form 1 Instructions 30

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 2023 tax year can claim the credit by submitting a completed Schedule CB, Circuit Breaker Credit, with their 2023 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 2023 Be sure to fill in the appropriate oval. If you were a renter in 2023 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. A taxpayer who owns a principal resi­ dence with a land area in excess of one acre or a multi-use building 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 (Sched­ ule CB, line 13), which corresponds to the por­ tion of the residence used and occupied as prin­ cipal residence. A taxpayer who owns a multiple family dwelling (a multi-family residence that in­ cludes the taxpayer’s personal residence), may only claim the taxpayer’s proportional share of the taxes (Schedule CB, line 10) or sewer and water use charges (Schedule CB, line 13) paid. For ex­ ample, where a condominium association pays one sewer and water bill for multiple owners, each owner may only claim the proportional share of the use charges attributable to the taxpayer’s con­ dominium (for example, the condominium own­ er’s percentage interest in the undivided interest of common areas and facilities). Line 2. Assessed Value of Principal Residence as of January 1, 2023 Enter the amount of the assessed value of your principal residence as of January 1, 2023. 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. If the assessed value is over $1,025,000, 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, 2023. 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 2023. 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 2023. This includes but is not limited to food stamps and welfare payments, disability income, gifts, sick pay, worker’s compensation and return of capital. Credit Calculation If you filled in the Homeowner oval in line 1, com­ plete lines 10 through 17, if you filled in the Renter oval in line 1, go to line 18. Line 10. Real Estate Taxes Paid in Calendar Year 2023 for Your Principal Residence Enter the amount of real estate taxes paid in cal­ endar year 2023. 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. 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 2023 for your principal residence. 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 2023 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 2023 Form 1 Instructions 31

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 2023 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 2023 Enter in line 18a the total amount of rent paid for your principal Massachusetts residence in 2023. 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. If you received any federal and/or state rent subsidy, or you rent from a tax-exempt entity, you do not qualify for the Circuit Breaker Credit. 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 under age 13, Dependent member(s) of household under 12, 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 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. 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 in­ structions 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 taxpayer should refer to this table for guidance when completing Schedule CMS.

2023 Massachusetts Income Tax Table at the 5.0% Rate Use this table to calculate tax for taxable 5.0% income (line 21) of not more than $24,000 Line 22 instructions: To find your tax on 5.0% Income (line 22), read down the tax table income column to the line containing the amount you entered in line 21. Then read across to the TAX column and enter this amount in line 22. If your taxable 5.0% income in line 21 is greater than $24,000, multiply the amount by .05. Enter the result in line 22. If your 5.0% income for the tax table is less than $10, your tax is 0. Note: If choosing the optional 5.85% tax rate, multiply line 21 and the amount in Schedule D, line 21 by .0585.

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, please consider electronic filing rather than using the paper form. There are benefits to e-filing your tax return. Last year, almost 95% of Massachusetts taxpayers e-filed their return. ◗ Refunds can be issued three times faster than filing on paper. ◗ Processing is much faster. ◗ Automatic corrections help you file a more accurate return. ◗ Security features are in place to protect e-filed tax returns. ◗ If you need to make a payment, you can set up an electronic payment and choose the date. You will save time and a trip to the post office. There are free filing options available for qualifying taxpayers. Please take a look at the opportunities at mass.gov/efile. Rather than using the paper form this tax season, consider all your choices, including the services of a tax preparer, or filing on your own with approved tax preparation software. I hope that e-filing is your first choice. Sincerely, Commissioner Geoffrey E. Snyder 83.5M 12/23 2024E02PRINTOFF48009 partially printed on recycled paper mass.gov/efile
