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. Enter the amount shown below for your filing status: • Single or married filing separately, enter $15,750 • Married filing jointly or qualifying surviving spouse, enter $31,500 • Head of household, enter $23,625 ... 2.

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.
