Idaho State Income Tax: What You Need to Know
Idaho uses a flat 5.8% income tax rate on all taxable income.
Idaho moved to a flat 5.8% income tax rate in 2023, simplifying its prior graduated system (which had rates up to 6%). Idaho taxable income is based on federal adjusted gross income with Idaho adjustments, and Idaho conforms to the federal standard deduction. Idaho has no city or local income tax — Boise, Idaho Falls, and all other Idaho cities add no local wage withholding. Idaho also offers a grocery tax credit to offset the impact of its sales tax on food.
On top of state taxes, all workers also pay federal income tax based on the 2026 progressive brackets, plus FICA taxes: Social Security (6.2% up to $176,100) and Medicare (1.45% on all wages).
Our calculator applies Idaho's 5.8% flat rate to your gross income as a simplified estimate. Actual state taxes may vary based on deductions, exemptions, and local taxes not captured in this estimate.

Frequently Asked Questions: Idaho Taxes
When did Idaho switch to a flat income tax rate?
Idaho enacted a flat 5.8% income tax rate starting January 1, 2023, as part of a broad tax reform package. Before 2023, Idaho used a graduated system with rates ranging from 1% to 6%. The reform simplified the tax structure and reduced the top rate slightly for higher earners.
How does Idaho's 5.8% flat rate compare to neighboring states?
Idaho's 5.8% rate is higher than Utah (4.65% flat) and Oregon's lower brackets but lower than Oregon's top rate (9.9%). Montana uses a graduated system topping at 6.75%. Nevada and Wyoming have no income tax. Within the region, Idaho sits in the middle — not the lightest tax burden, but far from the heaviest.
Does Idaho have a local income tax?
No. Idaho cities and counties cannot impose a local income tax on wages. Boise, Nampa, Meridian, and all other Idaho cities add no local tax withholding to your paycheck. Idaho workers pay only state and federal income taxes.
What is Idaho's grocery tax credit?
Idaho imposes its full 6% state sales tax on groceries, unlike many states that exempt or reduce the rate on food. To partially offset this, Idaho offers a grocery tax credit of $120 per taxpayer and $120 per dependent, claimed on the state income tax return. A family of four receives a $480 annual credit to help cover the food tax cost.
Does Idaho tax Social Security benefits?
Idaho taxes Social Security benefits to the extent they are taxable at the federal level. If your Social Security benefits are subject to federal income tax (which applies to higher-income recipients), the same portion is generally taxable in Idaho. Idaho does offer some retirement income deductions for older taxpayers to partially offset this.
What is Idaho's minimum wage in 2026?
Idaho's minimum wage is $7.25/hour — the federal minimum, with no state increase. Idaho has not raised its minimum wage above the federal floor. This is one of the lower state minimums in the country, and Idaho has no local minimum wage laws either.
