Idaho Paycheck Calculator
↻ Updated 2026 tax yearSee your real take-home pay in Idaho for 2026 — after federal income tax, Social Security and Medicare (FICA) and Idaho state income tax.
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.
