How Idaho taxes your paycheck

Idaho taxes wage income at a flat 5.3%, a single rate that applies no matter your income level. The calculator above applies that 5.3% rate after Idaho's sizable $16,100 standard deduction to estimate the state income tax withheld from your pay.

The large standard deduction — set at the same level as the federal figure — softens the flat rate considerably: because the first $16,100 of income is shielded, lower and middle earners pay an effective Idaho rate noticeably below 5.3%, even though the marginal rate never changes.

Where Idaho sits and the full paycheck picture

Idaho is a flat-rate state at 5.3%, a middle-of-the-road level paired with a generous standard deduction. No Idaho city or county taxes wages, so the state rate plus federal income tax and FICA is the full picture on your paycheck — there is no local income tax to factor in.

Frequently asked questions

What is the Idaho income tax rate for 2026?

Idaho uses a flat 5.3% rate for 2026, applied to taxable income after a $16,100 standard deduction. The rate is identical at every income level, though the large deduction lowers the effective rate for many earners. Enter your salary above to see the estimate.

Does Idaho have local income taxes?

No. No Idaho city or county levies an income tax on wages, so your only income tax is the flat 5.3% state rate, alongside federal income tax and FICA.
