EIN00046 03-02-2026 Page 2 of 52 General Information 2025 What’s New for 2025 Conformity to Internal Revenue Code (IRC) Idaho conforms to the IRC as of January 1, 2026. Notable exceptions include bonus depreciation, Idaho net operating losses, and Idaho Research Credit. Tax Rate Reduction Effective January 1, 2025, the individual income tax rate is 5.3%. Food Tax Credit The Food Tax Credit, formerly referenced as the Grocery Credit. • The Food Tax Credit has been increased to $155 per person. • If you want to submit copies of receipts for sales tax paid for food (up to $250), please see the instructions for Form 40 or 43. Who Must File Your residency status and income determine if you need to file an Idaho return. See the Residency and Income sections below. However, in general, it’s: • Every Idaho resident who must file a federal income tax return • Every part-year resident with a total of more than $2,500 gross income from either or both of these: ‚ All sources while a resident ‚ Idaho sources while a nonresident • Every nonresident with more than $2,500 gross income from Idaho sources To file an Idaho return, first complete your federal return. You need the federal return information to complete your Idaho return. Your Idaho filing status must be the same as your federal filing status. For example, if you file a joint federal return you also must file a joint Idaho return. The tax year and accounting method used on your Idaho return must match those used on your federal return. If a taxpayer dies before filing a current year return, the taxpayer’s spouse or personal representative must file the return. A personal representative can be an executor, administrator, or anyone who’s in charge of the deceased taxpayer’s property. Residency Are you a resident, a part-year resident, or a nonresident? The following will help you decide: • You’re an Idaho resident, even though you live outside of Idaho if all of the following are true: ‚ You think of Idaho as your permanent home. ‚ Idaho is the center of your financial, social, and family life. ‚ Idaho is the place you intend to return to when you’re away. • You’re also an Idaho resident if both of these are true: • You maintain a home in Idaho the entire year. ‚ You spend more than 270 days in Idaho during the tax year. • You’re a part-year resident if you moved into or out of Idaho during the tax year. You’re still a resident if both of these are true: ‚ You temporarily moved outside of Idaho. ‚ You moved back to Idaho after a temporary absence. • You’re a nonresident if your permanent home is outside of Idaho all year. • You’re also a nonresident if all of these are true: ‚ You’re an Idaho resident who lived outside of Idaho for at least 445 days in a 15-month period. ‚ After satisfying the 15-month period, you spent less than 60 days in Idaho during the year. ‚ You didn’t have a personal residence in Idaho for yourself or your family during any part of 2025. ‚ You didn’t claim Idaho as your federal tax home. ‚ You weren’t employed on the staff of a U.S. senator or representative. ‚ You didn’t hold an elective or appointive office of the U.S. government other than the armed forces or a career appointment in the U.S. Foreign Service. Note: The above exception to being an Idaho resident doesn’t apply to a qualified service member. Community property Idaho is a community property state. Idaho’s community property laws generally treat property and income acquired during marriage differently than other property. For more information visit tax.idaho.gov/commprop.

EIN00046 03-02-2026 Page 3 of 52 General Information 2025 (continued) Military Personnel Idaho law generally follows federal law regarding which type of military pay (active duty, disability, reserve, or retirement) is taxable. Qualified service member A qualified service member is: • Any member of the U.S. military. • A member of the National Guard that the President of the U.S. or U.S. Secretary of Defense calls to duty for more than 30 consecutive days to respond to a national emergency that the President declares and federal funds support. • A member of the commissioned corps of the National Oceanic and Atmospheric Administration (NOAA) in active service. • A member of the commissioned corps of the Public Health Service in active service. Military home of record The qualified service member’s residence is the same as their home of record. Idaho residents on active duty — stationed in Idaho If Idaho is your military home of record and you’re on active duty stationed in Idaho, Idaho taxes all of your military wages and all nonmilitary income regardless of the source. File Form 40. Idaho residents on active duty — stationed outside of Idaho Report all your Idaho income to Idaho if you meet all the following criteria: • You joined the military as an Idaho resident. • Idaho is your military home of record. • You were on active duty for 120 or more consecutive days. • You were stationed outside of Idaho for all or part of the year. File Form 40 if you’re single or if you’re married and your spouse also is an Idaho resident. File Form 43 if you’re married and your spouse is an Idaho nonresident, part-year resident, or military nonresident. • Check the “Idaho Resident on Active Military Duty” residency status box for yourself. • Check the applicable residency status box for your spouse. Idaho residents in the military don’t lose Idaho residency or domicile by being absent because of military orders. A qualified service member isn’t a resident of, or domiciled in, Idaho just by being stationed in Idaho. Nonresidents on active duty stationed in Idaho Idaho doesn’t tax your military income if your military home of record isn’t Idaho and you’re on active duty stationed in Idaho for all or part of the year. Idaho taxes nonmilitary income from Idaho sources. File Form 43 if your gross income from Idaho sources is more than $2,500. The instructions for Form 43 begin on page 15. Federal Military Spouses Residency Relief Act Idaho doesn’t tax the earned income of qualifying spouses of Idaho service members. This is due to the federal Military Spouses Residency Relief Act. As a service member’s spouse, you qualify for this exemption if both of these are true: • You’re married to a service member who’s serving in Idaho and the service member registered their home of record in another state. • You’ve moved to Idaho with the service member and have the same domicile (permanent residence) as the service member’s home of record. If you qualified for the Idaho income tax military spouse exemption, report any Idaho withholding on Form 43, line 66. National Guard members called to active duty in a combat zone Idaho follows federal law and provides income tax relief for service members on active duty in combat zones. Below is a summary of how these laws affect Idaho National Guard members: • All individual tax filing deadlines are extended for at least 180 days after your last day in a combat zone. • No interest or penalty accrues for nonpayment of individual income taxes while you’re in a combat zone. • If you’re enlisted or a warrant officer, you don’t owe tax on military pay received while in a combat zone. If you’re a commissioned officer, the monthly exclusion is capped at the highest enlisted pay plus any hostile fire or imminent danger pay received. • Write “COMBAT ZONE” and the date of deployment on top of the tax return you’re filing.

EIN00046 03-02-2026 Page 4 of 52 General Information 2025 (continued) • Federal law doesn’t cover business tax returns, employment taxes, or sales and use tax obligations. American Indians In general, if the federal government requires you to file a federal return, you must also file an Idaho return. See instructions on Idaho Form 39R or Form 39NR. On your Idaho return, you’ll be able to deduct all your income from working on the reservation when you meet all these criteria: • You’re enrolled in a federally recognized tribe. • You live and work on the reservation. • You include your reservation income on your Idaho return. If you have no other income, you don’t have to file an Idaho return. Income Idaho taxes two kinds of income: gross income and unearned income. When determining if you need to file, you’ll need to know your gross income. Dependents will also need to know their unearned income to see if they have to file. Gross income Gross income means all income you received in the form of money, property, goods, and services. It’s your income before you subtract any deductions. It includes, but isn’t limited to: • Income from wages, salaries, tips, interest, and dividends that isn’t exempt from tax • Self-employment income before expenses • Farm income before expenses • Rental income before expenses • The shareholders’ or partners’ share of gross income from S corporations and partnerships • Unemployment compensation • Certain scholarship and fellowship grants • Gains from sales of property • Pensions and annuities • Taxable Social Security benefits What not to include in gross income In your gross income, don’t include either of these: • Income the federal government exempts from income tax. Idaho also won’t tax this income. • Scholarships used for tuition, fees, supplies, books, and equipment required for courses leading to a degree. Unearned income Unearned income includes: • Taxable interest • Ordinary dividends • Capital gains distributions • Unemployment compensation • Taxable Social Security benefits, pensions, and annuities • Distributions of unearned income from a trust Earned income includes: • Salaries • Wages • Tips Idaho Resident Filing Requirements If your filing status is: And you are: And your gross income is: Married filing jointly Under 65 (both spouses) 65 or older (one spouse) 65 or older (both spouses) $31,500 $33,100 $34,700 Head of household Under 65 65 or older $23,625 $25,625 Single Under 65 65 or older $15,750 $17,750 Qualifying surviving spouse with dependent child Under 65 65 or older $31,500 $33,100 Married filing separately Any age $5 Idaho doesn’t require you to file an Idaho income tax return if all of these are true: You’re a resident, you’re filing a federal income tax return only to pay self-employment tax, and the IRS doesn’t otherwise require you to file a federal income tax return.

EIN00046 03-02-2026 Page 5 of 52 General Information 2025 (continued) • Professional fees • Taxable scholarships and fellowship grants Gross income is the total of your unearned and earned income. Which Form to Use Use Form 40 if you’re one of these: • Resident • Resident in the military Use Form 39R if you file Form 40 and claim any additions, subtractions, or certain credits. Use Form 43 if you’re either of these: • Part-year resident • Nonresident • Nonresident alien for federal purposes and Idaho requires you to file an Idaho income tax return Use Form 39NR if you file Form 43 and claim any additions, subtractions, or certain credits. When to File and Pay File your return and pay any tax due by one of these dates: • By April 15, 2026, for the 2025 calendar year • By the 15th day of the fourth month following the close of the fiscal year if you file on a fiscal year basis Idaho doesn’t require estimated tax payments. You can prepay at any time. See ways to pay electronically at tax.idaho.gov/epay, or mail your payment with Form 51.

If the credit applies to more than one state, use a separate Form 39R or 39NR for each state.

Rounding Round the amounts on your return to the nearest whole dollar. Round down if under 50 cents, round up if 50 cents or more. Extension of Time to File This isn’t an extension of time to pay your taxes—it’s an extension to file your return. You automatically get an extension of up to six months to file your return if you’ve paid at least one of these: • 100% of what you paid for state income taxes the year before • 80% of your current year’s tax liability You can avoid a penalty for late filing, but we must charge interest on the remaining tax until you pay it. Complete the worksheet on Form 51 to see if you meet the extension requirements. To avoid a penalty, pay online at tax.idaho.gov/epay or mail your payment with Form 51 by April 15, 2026. If you qualify for an extension to file your Idaho return, send the return and pay in full by October 15, 2026. Penalties Idaho law provides penalties for not filing tax returns by the due date, not paying tax due on time, not prepaying enough on extension returns, not paying when you file on extension returns, and other situations. For more information or to calculate a penalty, see our Interest and Penalties page at tax.idaho.gov/penalties. Interest We charge interest on the amount of tax due from the original due date of the return until paid at the rate of 6% per year (rate effective for 2026). Amended Returns Use Form 40 or 43 to amend your return. Check the amended return box at the top of the form and enter the reason for amending. See Amended Return on page 7 or 15 for more information. If your taxable income or tax credits change because of an audit, you must send written notice including an amended return to the Tax Commission within 120 days of the final determination. Include copies of all federal and state schedules that apply to you. If you owe additional Idaho tax and don’t send written notice within 120 days of the final federal determination, we apply a 5% negligence penalty. We charge interest on any tax due. If the final determination results in an Idaho refund, you must file an amended Idaho income tax return with the written notice. If the statute of limitations is closed, you have one year from the date of the final determination to file for the refund. Deadlines to Claim a Refund To qualify for a refund, you must file a return within the later of one of these timeframes: • Three years from the original return filing date. • Three years from the original return due date (not including extensions). For amended returns, you must file a claim for refund one of these timeframes: • Three years from the original return filing date. • One year from when the IRS closed its audit (for an amended return due to that audit).

EIN00046 03-02-2026 Page 8 of 52 Form 40 — Instructions 2025 (continued) Tax Calculation Line 12a Age 65 or Older The boxes you check here must match your federal return. • If you’re 65 or older, check the box for “Yourself.” • If you’re filing a joint return and your spouse is 65 or older, check the box for “Spouse.” • If your 65th birthday was on January 1, 2026, you may consider yourself 65 on December 31, 2025. Line 12b Blind The boxes you check here must match your federal return. • Check the box for “Yourself” if you’re blind. • If you’re filing a joint return and your spouse is blind, check the box for “Spouse.” Line 12c Claimed Dependent Check this box if someone else, such as a parent, can claim you as a dependent. Lines 13 – 16 Standard Deduction Most people can find their standard deduction by looking at the instructions to the left of Form 40, line 16. Use the Standard Deduction Worksheet beginning on this page to calculate your standard deduction if either of these is true: • You checked any boxes on lines 12a through 12c. • Someone can claim you or your spouse, if filing jointly, as a dependent. You can use either your federal itemized deductions or standard deduction, whichever benefits you more. You Must Itemize If: • Your filing status is married filing separately and your spouse itemizes. • You had dual status as a nonresident alien for part of 2025, and you were a resident alien or U.S. citizen during the rest of the year. You don’t have to itemize if you file a joint return with your spouse who was a U.S. citizen or resident at the end of 2025, and you and your spouse agree to be taxed on your combined worldwide income. Idaho requires you to subtract state income tax, local income tax, or general sales tax on federal Schedule A from your total itemized amount before you use that amount to reduce your income. Because of this addback, it might be more beneficial to itemize for federal purposes but use the standard deduction for Idaho. If the IRS considers you or your spouse a nonresident alien and you aren’t from India, your standard deduction is zero. If you’re nonresident aliens from India, use the standard deduction for your filing status. If line 15 is more than line 16, use your itemized deductions on line 15. If line 16 is more than line 15, use your standard deduction on line 16. Itemized Deductions If you use federal Schedule A to itemize, follow these instructions for line 14. If federal Schedule A, line 5d, is: • $40,000 or less ($20,000 if married filing separately), enter the amount from federal Schedule A, line 5a. • More than $40,000 ($20,000 if married filing separately), subtract lines 5b and 5c from line 5e, and enter the amount here. Enter zero for any result less than zero. Federal Foreign Tax Credit: If you claim the federal foreign tax credit, Idaho allows that amount as a deduction. Idaho doesn’t have a credit that matches the federal foreign tax credit. Add the amount you claimed for the federal foreign tax credit to your Idaho itemized deductions. Standard Deduction Worksheet 1.

If the credit applies to more than one state, use a separate Form 39R for each state. See instructions, page 37. You might qualify for a credit for tax that a pass- through entity (PTE) paid to another state on your behalf. The PTE should report that payment information to you. Examples of income that both Idaho and another state might tax include: • Wages earned in another state that has an income tax, such as Oregon or Utah, while you’re living in Idaho. • Income from a business or profession earned in another state that has an income tax while you’re a resident of Idaho.

Typically, the custodial parent claims the qualifying child. The noncustodial parent can claim the child if either of these is true:

EIN00046 03-02-2026 Page 10 of 52 Form 40 — Instructions 2025 (continued) • A court has awarded the right to claim the child for tax purposes to the noncustodial parent. • The custodial parent signs a written declaration that the noncustodial parent can claim the child for the child tax credit.

Line 25 Other Deductions You might qualify for an Idaho deduction if you claimed any of the following items on federal Schedule 1, lines 11, 12, and 24 relating to: • Educator expenses • Reservists • Performing artists • Fee-based government officials • Jury duty pay • A write-in deduction for rental of personal property • Reforestation amortization and expenses* • Attorney fees and court costs To calculate the deduction allowed on your Idaho return: 1. Divide the income relating to that item included in Idaho total income by the income relating to the item included in federal adjusted gross income. You’ll get a percentage (can’t exceed 100%). 2. Multiply this percentage by the deduction claimed on your federal return. 3. Repeat steps 1 and 2 for each deduction above. 4. Total the result for each deduction, and enter the amount on line 25. 5. Include a copy of your calculations with your return. Example: Divide Idaho jury pay included in Idaho total income by total jury pay included in federal adjusted gross income to arrive at a percentage (can’t exceed 100%). Multiply that percentage by the amount of jury pay claimed as a deduction on your federal return. *If there’s no income from the related timber operations for the year of the reforestation deduction, the deduction for reforestation is based on the percentage of property in Idaho to the total property that relates to the reforestation amortization and expense. Line 28 Adjusted Gross Income Column A: This must be the same amount of adjusted gross income as reported on your federal Form 1040 or 1040-SR, line 11. Column B: This is Idaho adjusted gross income. Enter the amount from line 27. If your Idaho adjusted gross income is negative, see Idaho Form 56 and instructions. Tax Computation Line 32a Age 65 or Older If you’re 65 or older, check the box for “Yourself.” If you’re filing a joint return and your spouse is 65 or older, check the box for “Spouse.” If your 65th birthday was on January 1, 2026, you can consider yourself 65 on December 31, 2025. The boxes you check must match your federal return. Line 32b Blind Check the box for “Yourself” if you’re blind. If you’re filing a joint return and your spouse is blind, check the box for “Spouse.” The boxes you check must match your federal return. Line 32c Claimed Dependent Check this box if someone else, such as a parent, can claim you as a dependent. Lines 33 – 36 Standard Deductions Most people can find their standard deduction by looking at the instructions to the left of line 36 on Form 43. Use the Standard Deduction Worksheet on page 20 to calculate your standard deduction if you did either of these: • You check any boxes on lines 32a through 32c. • Someone can claim either you or your spouse as a dependent, if filing jointly. You can use either your federal itemized deductions or standard deduction, whichever benefits you more. You must itemize if: • You’re married filing a separate return (filing status 3), and your spouse itemizes. • You were a nonresident alien for any part of 2025 (exception for taxpayers from India. See below). You don’t have to itemize if you file a joint return with your spouse who was a U.S. citizen or resident at the end of 2025, and you and your spouse agree to be taxed on your combined worldwide income. Idaho requires that you subtract state income tax, local income tax or general sales taxes reported on federal Schedule A from your total itemized amount and then use the resulting figure to reduce your income. Because of this addback, it might be more beneficial to itemize for federal purposes but use the standard deduction for Idaho. If the IRS considers you or your spouse nonresident aliens and you aren’t from India, your standard

EIN00046 03-02-2026 Page 20 of 52 Form 43 — Instructions 2025 (continued) deduction is zero. If you’re nonresident aliens from India, use the standard deduction for your filing status. If line 35 is more than line 36, use your itemized deductions on line 35. If line 36 is more than line 35, use your standard deduction on line 36. Itemized Deductions If you use federal Schedule A to itemize, use the following instructions for line 34: • If federal Schedule A, line 5d, is: ‚ $40,000 or less ($20,000 if married filing separately), enter the amount from federal Schedule A, line 5a. ‚ More than $40,000 ($20,000 if married filing separately), subtract lines 5b and 5c from line 5e, and enter the amount here. Enter zero for any result less than zero. Federal foreign tax credit: If you claim the federal foreign tax credit, Idaho allows that amount as a deduction.

The Idaho Retirement Benefits Deduction for Retired Service Members. You must meet at least one of the following: • Classified as disabled (any age), or • Age 62 or older, or • Under age 62, employed during the year, and received sufficient income from such employment to be required to file a federal return. The Idaho Retirement Benefits Deduction for all other retirees has a two-part qualification. You must qualify for both parts to receive this deduction. Part One – Age, Disability, and Marital/Filing Status The recipients must be at least age 65 or be classified as disabled and be at least age 62. The following individuals are classified as disabled: • An individual recognized as disabled by the Social Security Administration, the Railroad Retirement Board, or the Office of Management and Budget • A veteran of a U.S. war with a service-connected disability rating of 10% or more • A veteran of a U.S. war with a nonservice-connected disability pension • A person who has a physician-certified permanent disability with no expectation of improvement If you’re married, you can’t claim this deduction if you file separately. If you’re an unremarried widow or widower of a pensioner and receive qualifying survivor benefits, you might be eligible to claim the retirement benefit deduction if you meet the age/disability requirements. Part Two – Qualified Retirement Benefits The recipients must meet the requirements in Part One, and their qualified retirement benefits must be one of the following: • Civil Service Employees: Retirement annuities paid by the U.S. Civil Service Retirement System (CSRS), the Foreign Service Retirement and Disability System (FSRDS), or the offset programs of these two systems. ‚ To qualify for the deduction, the employee must have established eligibility before 1984. ‚ Retirement annuities paid to a retired federal employee under the Federal Employees Retirement System (FERS) don’t qualify for the deduction. You can tell if your benefits are paid under the CSRS or FERS by looking at the first digit of the account number on your CSA-1099, if you received one.

EIN00046 03-02-2026 Page 32 of 52 Form 39R — Instructions 2025 (continued) ‚ If the first digit is 0, 1, 2, 3, or 4, the benefits are paid out of CSRS. ‚ If the first digit is 7 or 9, the benefits are paid out of FERS and don’t qualify. ‚ If the first digit is 8, look at your Notice of Annuity Adjustment from the Office of Personnel Management. The notice shows how much of your benefits are paid from CSRS and how much are paid from FERS. Only the portion paid from CSRS qualifies for this deduction. • Idaho Firefighters: Retirement benefits paid by the Public Employee Retirement System of Idaho (PERSI) relating to the Firefighters Retirement Fund. If you received a 1099R and your account number includes the FRF (Firefighters Retirement Fund) designation, your benefits might qualify for the deduction. Benefits paid out of the PERSI Base Plan don’t qualify for the deduction. • Police Officers of an Idaho City: Retirement benefits paid from the Police Retirement Fund that no longer admits new members and, on January 1, 2012, was administered by an Idaho city or PERSI. Also, benefits that PERSI paid relating to Idaho police officer employment not included in the federal Social Security retirement system. For example, benefits paid out of the city police retirement funds for the cities of Coeur d’Alene, Lewiston, and Pocatello might qualify for the deduction. Similarly, benefits that PERSI paid relating to the old Idaho Falls Police Retirement Fund might qualify for the deduction. If you received a 1099R and your account number includes the IFP (Idaho Falls Police) designation, your benefits might qualify. Benefits paid out of the PERSI Base Plan don’t qualify for the deduction. Disability pension that the federal Railroad Retirement Act paid might not be included on your Form RRB-1099 or RRB-1099-R, if you’re under the minimum retirement age. Instead it might be included on Form 1040 or 1040-SR, line 1 as wages. Line 9 Technological Equipment Donation Enter the lesser of cost or fair market value of technological equipment donated to one or more of these Idaho educational institutions or libraries located in Idaho: • Public or nonprofit private elementary or secondary school. • Public or nonprofit private college or university. • Public library or library district. Items that qualify for this deduction are limited to computers, computer software, and scientific equipment or apparatus manufactured within five years of the date of donation. The amount deducted can’t reduce Idaho taxable income to less than zero. You can’t carry any unused deduction to another year. Include your distributive share from the appropriate column of Form ID K-1, Part IV, line 26. The deduction from a pass-through entity can’t be more than the amount of pass-through income minus deductions of the entity making the contribution. Line 10 Idaho Capital Gains Deduction You might be able to deduct 60% of the capital gain net income reported on federal Schedule D from the sale of any of the qualified Idaho property described below: (a) Real property held for at least 12 months (b) Tangible personal property used in a revenue-producing enterprise and held for at least 12 months.

EIN00046 03-02-2026 Page 33 of 52 Form 39R — Instructions 2025 (continued) don’t have to be in the same tax year. Enter your nontaxable military wages. Don’t include military wages earned while stationed in Idaho. Your W-2 doesn’t show this amount separately, and you might have to calculate the amount of income earned outside of Idaho. You should see your unit of assignment or use your orders in making the calculation. Include a copy of your worksheet. National Guard or Reserve pay, including annual training pay, generally doesn’t qualify as active-duty pay unless you’ve been called into full-time duty for 120 days or more. However, your active-duty military wages earned outside Idaho qualify for this deduction if both of these are true: • You’re a commissioned officer of the Public Health Service or of the National Oceanic and Atmospheric Administration militarized by the President of the United States. • You’re attached to the armed forces. If this is true, enter your active-duty wages earned outside Idaho on this line. Line 12 Adoption Expenses You can deduct some expenses related to the adoption of a child. • You can claim legal and medical expenses up to a maximum of $10,000 per adoption. • If you incur expenses in two or more years, deduct the costs in the year paid until you meet the $10,000 limit. Travel expenses don’t qualify. Expenses related to an unsuccessful attempt to adopt don’t qualify. If you claim expenses in a year before you find the adoption won’t succeed, file an amended return to add back any deduction claimed for the unsuccessful attempt. Line 13 Idaho Medical Savings Account Contributions and Interest You can contribute up to $10,000 ($20,000 if married filing a joint return) to an Idaho medical savings account and deduct the contribution.

You establish the account to pay the eligible medical expenses for you as the account holder and your dependents. On this line include: • Your qualifying contributions. • Interest earned on the account, but only if it’s on Form 40, line 7. Enter the name of the financial institution and your account number in the spaces provided. Line 14 Idaho College Savings Program You can deduct up to $6,000 ($12,000 if married filing a joint return) per year in contributions to accounts in the Idaho College Savings Program (IDeal). Contributions to an out-of-state college savings program don’t qualify. Designate the account owner and beneficiary at the time you establish the account. The account owner can make withdrawals for a qualified education expense for the beneficiary as provided in 26 U.S.C. section 529. Whoever withdraws the money must report it as income. Find more information at idsaves.org or by calling toll free (866) 433-2533. Line 15 Home for the Aged or Developmentally Disabled You can claim no more than three deductions of $1,000. If you claim this deduction, you can’t claim the $100 credit in Part E. Home for the Aged You can deduct $1,000 for each immediate family member age 65 or older (not including yourself or your spouse) for whom you do both of these: • Maintain a household for. • Provide more than one-half of that family member’s support for the year. Developmentally Disabled You can deduct $1,000 for each family member who’s developmentally disabled, including yourself and your spouse, for whom you do both of these: • Maintain a household for. • Provide more than one-half of this family member’s support for the year. Developmental disability means a chronic disability that meets all of these requirements: • It’s attributable to an impairment such as: ‚ An intellectual disability. ‚ Cerebral palsy.

EIN00046 03-02-2026 Page 34 of 52 Form 39R — Instructions 2025 (continued) ‚ Epilepsy. ‚ Autism. ‚ Other condition found to be closely related to, or similar to, one of these impairments. • Results in substantial functional limitation in three or more of these areas of life activity: ‚ Self-care ‚ Receptive and expressive language ‚ Learning ‚ Mobility ‚ Self-direction ‚ Capacity for independent living ‚ Economic self-sufficiency • Reflects the need for a combination and sequence of special, interdisciplinary, or generic care, treatment, or other services which are of lifelong or extended duration and individually planned and coordinated. If you maintained the home for the family member for less than a full year, you can take a deduction of $83.33 for each month you maintained the home. A family member is any person who meets the relationship test to be claimed as a dependent on income tax returns. See the federal Form 1040 instructions for more information. Maintaining a household means paying more than one-half of the expenses incurred for the benefit of all the household’s occupants. Social Security benefits aren’t support provided by you but must be included in the calculation of total support provided. Some examples of expenses of maintaining a household include: • Property taxes • Mortgage interest • Rent • Utility charges • Upkeep and repairs • Property insurance • Food consumed on the premises Line 16 Idaho Lottery Winnings You can deduct Idaho lottery prizes of less than $600 per prize included in federal adjusted gross income on Form 40, line 7.

You can’t deduct either of these: • Income earned off a reservation. • Income earned on a reservation, if you live off a reservation. Line 18 Health Insurance Premiums Deduct premiums you paid for health insurance for yourself, your spouse, and your dependents if those premiums haven’t already been deducted or excluded from your income. If you claimed a deduction for health insurance premiums on your federal Form 1040 or 1040-SR, Schedule A, use the worksheet on page 35 to calculate the Idaho deduction. The worksheet follows the priority that itemized deductions first apply to health insurance premiums and then to long-term care insurance. Idaho Medical Savings Account You can’t take the deduction for money you take from your Idaho medical savings account to pay health insurance premiums. This is because you’ve already deducted health insurance costs, or they’ve already been accounted for. Salary Reduction Plans You can’t include premiums paid through a cafeteria plan or other salary-reduction arrangement in the Idaho deduction for health insurance costs. For example, health insurance payments deducted from your paycheck pretax don’t qualify for the deduction. Business Deductions You can’t include in this Idaho deduction the premiums you already deducted as a business expense. This includes self-employed health insurance premiums deducted in arriving at federal adjusted gross income. Social Security Medicare A, B, and D Medicare A: • Generally, you can’t deduct the amount paid for employer-required Social Security Medicare A. This is the amount listed as a deduction on almost every federal Form W-2.

EIN00046 03-02-2026 Page 35 of 52 Form 39R — Instructions 2025 (continued) • You can deduct premiums for Medicare A if you voluntarily enrolled, or if you aren’t covered under Social Security. Medicare B and D: • You can deduct the premiums for Medicare B, D, or both if you voluntarily enrolled. Idaho Standard Deduction If you use the Idaho standard deduction instead of itemizing your deductions for Idaho purposes, you don’t have to reduce your health insurance costs by any amount claimed as a federal itemized deduction. Federal Itemized Deduction Limitations Reduce the amount of medical expenses allowed as a deduction on federal Form 1040 or 1040-SR, Schedule A, by 7.5% of adjusted gross income. Line 19 Long-term Care Insurance Premiums You can deduct premiums you paid for qualified long-term care insurance that you haven’t otherwise deducted or accounted for. If you claimed a deduction for long-term care insurance on your federal Form 1040 or 1040-SR, Schedule A, use the following worksheet to calculate the long-term care insurance allowed as an Idaho deduction. Qualified long-term care insurance includes any insurance policy that provides coverage for at least 12 consecutive months for yourself, your spouse, or your dependents for one or more necessary diagnostic, preventive, therapeutic, rehabilitative, maintenance, or personal care services provided in a setting other than an acute care unit of a hospital. Group and individual annuities and life insurance policies that directly provide or supplement long-term care insurance qualify. This includes a policy that provides for payment of benefits based on cognitive impairment or loss of functional capacity. Qualified long-term care insurance doesn’t include any insurance policy that’s offered primarily to provide coverage for any of these: • Basic Medicare supplement • Basic hospital expense • Basic medical surgical expense • Hospital confinement indemnity • Major medical expense • Disability income or related asset protection • Accident only • Specified disease or specified accident • Limited benefit health Life insurance policies that accelerate death benefits generally don’t qualify.

Line 22 First-time Home Buyer Savings Account You can contribute up to $15,000 ($30,000 if married filing a joint return) to a first-time home buyer savings account and deduct the contribution. Deposits into the account can’t exceed $100,000 for the lifetime of the account. A first-time home buyer savings account is established in Idaho with a bank, savings and loan association, credit union, or trust company authorized to act as a fiduciary.

See the instructions for Itemized or Standard Deductions. Part C — Credit for Income Tax Paid to Other States When both Idaho and another state tax the same income, you might qualify for a credit for tax paid to the other state. Use this section to calculate the credit. You must include a copy of the other state’s income tax return and Form 39R. If the credit applies to more than one state, use a separate Form 39R for each state. You might qualify for a credit for tax that a pass-through entity (PTE) paid to another state on your behalf. The PTE should report that payment information to you. Include a copy of Form ID K-1. Examples of income that both Idaho and another state might tax include: • Wages earned in another state that has an income tax, such as Oregon or Utah, while living in Idaho. • Income from a business or profession earned in another state that has an income tax, while a resident of Idaho. Line 1. Enter the tax shown on Form 40, line 20. Line 2. Enter the total portion of federal adjusted gross income derived in the other state, modified to reflect Idaho additions and subtractions. In calculating the income derived in the other state, you must reverse any adjustments to federal taxable income that the other state allows but Idaho doesn’t. Enter your adjusted gross income from the other state restated to a basis comparable to Idaho adjusted income. For example, if the other state taxes interest received from U.S. obligations, deduct this amount from the other state’s adjusted gross income since Idaho doesn’t tax this interest. If your income derived in the other state includes income from an S corporation, partnership, trust, or estate, enter your share of the entity’s taxable income correctly reported to the other state. Also include any other Idaho adjusted gross income from sources in the other state. Line 3. Enter your Idaho adjusted income from Form 40, line 11, if you reported the double-taxed income on an individual income tax return in the other state. Line 4. Divide line 2 by line 3. Round to four digits to the right of the decimal point. For example, you’d round .66666 to .6667 and enter it as 66.67%. Line 6. Enter the other state’s tax due from its tax table or rate schedule minus its income tax credits. Don’t subtract state and local tax (SALT) workaround payments or credits. If your income derived in the other state was reported on a composite or group return that an S corporation or partnership filed, enter your proportionate share of the tax that the S corporation or partnership paid, minus your proportionate share of the income tax credits. Income tax credits are those credits that relate to income tax excluding SALT workaround payments or credits. An example of a credit that isn’t an income tax credit is a special fuels or gasoline tax credit or refund. Line 7. Your allowable credit for tax paid to other states is the smaller of lines 5 or 6. Enter this amount on Form 40, line 21. This credit can’t exceed the Idaho tax due on Form 40, line 20.

The following individuals are classified as disabled: • An individual recognized as disabled by the Social Security Administration, the Railroad Retirement Board, or the Office of Management and Budget. • A veteran of a U.S. war with a service-connected disability rating of 10% or more. • A veteran of a U.S. war with a nonservice-connected disability pension. • A person who has a physician-certified permanent disability with no expectation of improvement. If you’re married, you can’t claim this deduction if you file separately. If you’re an unremarried widow or widower of a pensioner and receive qualifying survivor benefits, you might be eligible to claim the retirement benefit deduction if you meet the age/disability requirements. Part Two – Qualified Retirement Benefits The recipients must meet the requirements in Part One, and their qualified retirement benefits must be one of the following: • Civil Service Employees: Retirement annuities paid by the U.S. Civil Service Retirement System (CSRS), the Foreign Service Retirement and Disability System (FSRDS), or the offset programs of these two systems. ƒ To qualify for the deduction, the employee must have established eligibility before 1984. ƒ Retirement annuities paid to a retired federal employee under the Federal Employees Retirement System (FERS) don’t qualify for the deduction.

The notice shows how much of your benefits are paid from CSRS and how much are paid from FERS. Only the portion paid from CSRS qualifies for this deduction. • Idaho Firefighters: Retirement benefits paid by the Public Employee Retirement System of Idaho (PERSI) relating to the Firefighter Retirement Fund. If you received a 1099R and your account number includes the FRF (Firefighter Retirement Fund) designation, you can include those benefits in your deduction calculation.

Also, benefits that PERSI paid relating to Idaho police officer employment not included in the federal Social Security retirement system. For example, benefits paid out of the city police retirement funds for the cities of Coeur d’Alene, Lewiston, and Pocatello might qualify for the deduction. Similarly, benefits that PERSI paid relating to the old Idaho Falls Police Retirement Fund might qualify for the deduction. If you received a 1099R and your account number includes the IFP (Idaho Falls Police) designation, you can include those benefits in your deduction calculation. Benefits paid out of the PERSI Base Plan don’t qualify for the deduction. Disability pension that the federal Railroad Retirement Act paid might not be included on your Form RRB-1099 or RRB-1099-R, if you’re under the minimum retirement age. Instead it might be included on Form 1040 or 1040-SR, line 1 as wages. Line 22g. Enter the amount of qualified retirement benefits included in Idaho gross income.
