The solid line is what you keep in Idaho; the dashed line is the median of all 51 jurisdictions at the same salary (single filer). Where the lines cross is where Idaho stops being the better deal.
Figure B Take-home pay as salary rises
If every dollar you earned from January 1 went to tax, this is the day you'd stop paying and start keeping.
Figure C The tax year, day by day
You work until Mar 21 — day 80 of 365 — to pay your total 2026 tax bill of $16,274. Everything you earn after that is yours.

Single filer, no pre-tax deductions. The $75,000 row is the calculator's default above.
The state-specific rules behind the numbers above — the things a generic calculator gets wrong about Idaho.
Idaho is not quite a pure flat tax. A single filer pays 0% on the first $4,811 of taxable income and 5.30% on everything above it, so low earners owe nothing at the state level even before credits. The standard deduction mirrors the federal amount — $16,100 for a single filer in 2026 — because Idaho starts from federal taxable income.

Idaho is one of the few states that charges its full 6% sales tax on groceries, and it offsets that with a refundable food tax credit claimed on the income tax return. The credit rose from $120 per person in 2023–2024 to $155 per person for 2025 and later years, for you, a spouse and each dependent — $620 for a family of four, no receipts needed. Households that keep receipts can instead claim the actual grocery sales tax paid, up to $250 per person. Because it is refundable, you can claim it even if you owe no Idaho income tax.

Idaho does not tax Social Security or Railroad Retirement benefits — any amount included in federal AGI is subtracted on the Idaho return. Pensions, 401(k) and IRA withdrawals are otherwise taxed at the 5.30% rate, subject to Idaho's deduction for qualifying retirement benefits under Idaho Code § 63-3022A, and military retirement pay is now fully exempt following the 2025 legislation.

House Bill 40, signed in March 2025 and retroactive to 1 January 2025, cut Idaho's individual rate from 5.695% in 2024 to 5.30%, continuing a fall from 6.5% before 2023 and 5.8% in 2023. The corporate rate was aligned to 5.30% at the same time.

5.30% on taxable income above $4,811 for a single filer — the first $4,811 is taxed at 0%. On a $75,000 salary for a single filer, the calculator on this page puts Idaho state tax at $2,867, leaving net pay of $58,726 after federal tax of $7,670 and FICA of $5,738, for total tax of $16,274.
The food tax credit is $155 per person for 2025 and later years — up from $120 in 2023 and 2024 — claimed for yourself, a spouse and each dependent. It is refundable, and if you keep grocery receipts you may claim actual sales tax paid instead, up to $250 per person.
No. Idaho fully exempts Social Security and Railroad Retirement benefits, even if part of them is taxable on your federal return. Other retirement income such as pensions and IRA withdrawals is generally taxed at 5.30%, subject to the state's retirement-benefits deduction.
Idaho mirrors the federal standard deduction, so $16,100 for a single filer in 2026. On top of that, the first $4,811 of taxable income sits in a 0% bracket.
Idaho charges its 6% state sales tax on food bought for home consumption, unlike most states. The refundable food tax credit is the offset: it returns $155 per person through the income tax return each year rather than exempting food at the register.
Yes. House Bill 40 cut the rate from 5.695% in 2024 to 5.30% from 1 January 2025, retroactively. No further rate cut took effect for 2026.
