Taxes in Idaho
Idaho has simplified its tax code by adopting a flat state income tax rate of 5.3% for 2026. This replaces the old multi-bracket system, meaning every dollar of your taxable income is taxed at the same competitive rate. Idaho also aligns its standard deduction with federal levels, which significantly lowers your taxable base. While Idaho doesn't have city or county income taxes, you should be aware of the Grocery Tax Credit. Because Idaho is one of the few states that taxes groceries at the full sales tax rate, it provides residents with a credit (usually around $120–$155 per person) on their tax return to help offset that cost.
All Idaho employees are also subject to Federal Income Tax and FICA (Social Security and Medicare) withholdings.
Federal and FICA Pillars in Idaho
Federal Income Tax
Federal taxes are usually the largest deduction from your Idaho paycheck, following the progressive IRS brackets (10% to 37%). For 2026, the federal standard deduction is $16,100 for single filers, ensuring a solid chunk of your Idaho earnings is shielded from federal withholding from the very first day.
FICA Withholdings
FICA is the mandatory 7.65% total for Social Security and Medicare. In 2026, the 6.2% Social Security tax only applies to the first $184,500 of your gross income. If you're a high earner in Idaho, you'll see your take-home pay increase slightly once you cross this annual threshold.
