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 ($15,000 for single filers in 2026). Idaho has no city or local income tax — Boise, Nampa, Meridian, and all other Idaho cities add no local wage withholding. Idaho has one quirk worth knowing: it applies its full 6% state sales tax to groceries, which is unusual among states. To partially offset this, Idaho offers a grocery tax credit ($120 per taxpayer and $120 per dependent) claimed on the state tax return. Idaho's overall cost of living has risen sharply due to significant in-migration from California and the Pacific Northwest — Boise in particular saw substantial housing price increases from 2020 to 2023, though the market has cooled since. The combination of no local income taxes, a relatively simple flat-rate system, and strong outdoor recreation access makes Idaho attractive for remote workers relocating from higher-tax states.
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 (H0436). Before 2023, Idaho used a graduated system with rates ranging from 1.125% to 6.5% across multiple brackets. The reform simplified withholding, slightly reduced the top rate, and eliminated the bracket structure that caused marginal rate jumps. Idaho's taxable income conforms to federal AGI with Idaho-specific adjustments, and the state conforms to the federal standard deduction.
How does Idaho's 5.8% flat rate compare to neighboring states?
Idaho's 5.8% is higher than Utah (4.65% flat) and significantly higher than Nevada and Wyoming (no income tax). Montana uses a graduated system topping at 5.9% — very close to Idaho. Oregon's rates range from 4.75% to 9.9%, making Idaho cheaper for most middle-income earners but more expensive than Oregon's lowest brackets. Washington state has no income tax on wages. Among the Rocky Mountain states, Idaho sits in the middle of the pack — not the lowest, but far from the highest.
Does Idaho have a local income tax?
No. Idaho state law prohibits cities and counties from imposing a local income tax on wages. Boise, Nampa, Meridian, Coeur d'Alene, and all other Idaho municipalities add no local tax withholding to paychecks. Idaho workers pay only state income tax (5.8%) and federal income tax. This is simpler than states like Indiana (92 county taxes), Ohio (600+ city taxes), or Maryland (county surcharges) where local taxes layer on top of state rates.
What is Idaho's grocery tax credit and why does it exist?
Idaho charges its full 6% state sales tax on groceries — unlike many states that exempt food from sales tax. To partially offset this burden on lower-income households, Idaho offers a grocery tax credit of $120 per taxpayer and $120 per qualifying dependent, claimed on the state income tax return. A single person gets $120; a family of four gets $480. The credit is refundable, meaning you can receive it even if you owe no state income tax. Critics argue the fixed-dollar credit is regressive — the same $120 regardless of how much you actually spent on groceries — but it provides at least partial relief.
Does Idaho tax Social Security benefits?
Idaho taxes Social Security benefits to the extent they are taxable at the federal level — meaning if your combined income exceeds the federal threshold, the portion of Social Security subject to federal tax is also subject to Idaho state tax. However, Idaho provides a retirement income deduction for older residents: taxpayers age 65 and older (or age 62 and disabled) can deduct up to $5,765 for single filers and $8,648 for joint filers of retirement income, which includes Social Security. This deduction meaningfully reduces or eliminates Idaho tax on Social Security for many retirees.
What is Idaho's minimum wage in 2026?
Idaho's minimum wage is $7.25/hour — the federal floor. Idaho has not raised its minimum wage above the federal minimum and preempts local governments from setting higher local minimums. This is among the lowest effective minimums in the Mountain West: Nevada's minimum is $12.00/hour, Colorado's is $14.81/hour, and Montana's is $10.55/hour. For workers in the Treasure Valley, the low minimum wage combined with rising housing costs has pushed affordable housing further out of reach — a key local policy debate in the Boise metro area.
