How Idaho paycheck taxes work
Idaho moved to a single flat income tax rate of 5.3% in 2025, cut from a top rate of 5.695% the year before, and that flat rate carries into 2026. Idaho's standard deduction matches the federal standard deduction rather than setting its own amount, so the same deduction this calculator uses for your federal tax also reduces your taxable income for Idaho state tax.
Federal income tax is calculated using the 2026 IRS tax brackets after subtracting your standard deduction, based on your filing status. FICA is a flat 6.2% Social Security tax (up to the annual wage base) plus 1.45% Medicare tax, with an additional 0.9% Medicare tax on income above $200,000 (single) or $250,000 (married filing jointly).

Frequently asked questions
Does Idaho have a state income tax?
Yes. Idaho taxes wage income at a flat 5.3% rate. See the state-specific section above for exactly how that applies to your filing status.
How is federal income tax calculated on a Idaho paycheck?
Federal tax is calculated on taxable income (gross pay minus your standard deduction) using the 2026 IRS marginal tax brackets, which apply the same way in every state, including Idaho. See "How Paycheck Withholding Works" for the full breakdown.
What is FICA and how much is withheld?
FICA is 6.2% Social Security (up to the annual wage base) plus 1.45% Medicare, with an additional 0.9% Medicare tax above $200,000 (single) or $250,000 (married filing jointly). It applies the same way in every state, including Idaho.
Is this calculator exact?
No, it's an estimate based on standard 2026 tax tables and common assumptions. It doesn't account for every possible deduction, credit, filing situation, or local tax. For Idaho specifically, this estimate uses the same standard deduction Idaho borrows directly from the federal figure, so it tracks fairly closely to what most flat-rate filers actually see withheld. See the disclaimer above the breakdown for details.
