The cost of the insulating material is the only thing that qualifies. • Windows that replace less efficient existing windows. • Storm windows. • Weather stripping and caulking. • Duct sealing and insulation. Duct sealing requires mechanical fastening of joints and mastic sealant. • The cost of labor to install the energy efficiency upgrades is also deductible.

EIN00046 03-02-2026 Page 30 of 52 Form 39R — Instructions 2025 (continued) Enter the energy efficiency upgrade installed in your Idaho residence. If you have more than one upgrade, enter multiple.

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. A revenue-producing enterprise means: • Producing, assembling, fabricating, manufacturing, or processing any agricultural, mineral, or manufactured product. • Storing, warehousing, distributing, or selling at wholesale any products of agriculture, mining, or manufacturing. • Feeding livestock at a feedlot. • Operating laboratories or other facilities for scientific, agricultural, animal husbandry, industrial research, development, or testing. (c) Cattle and horses held for at least 24 months and other livestock used for breeding held for at least 12 months. (d) Timber held for at least 24 months. (e) Certain sales of partnership interests. (Idaho Code section 63-3022H(3)(f)) Note: Gains from the sale of stocks, goodwill, and other intangibles don’t qualify. Complete Idaho Form CG to calculate your capital gains deduction. Line 11 Active Duty Military Pay Earned Outside of Idaho If you’re serving in the U.S. military on active-duty that’s continuous and uninterrupted for 120 days, Idaho doesn’t tax your active-duty military wages for service outside of Idaho. The continuous 120 days

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.

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 can’t deduct: • Reimbursements redeposited into your Idaho medical savings account. • Amounts deducted on federal Form 1040 or 1040-SR. An Idaho medical savings account is generally established with a bank, savings and loan, or credit union. You establish the account to pay the eligible medical expenses for you as the account holder and your dependents.

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.

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.

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.
