What is Idaho's income tax rate?

Idaho uses a flat income tax of 5.695% for the 2024 tax year. The rate applies to taxable income above a small zero-bracket floor, and Idaho conforms to the federal standard deduction, so most workers see a single flat state rate on their wages.

Does Idaho have local or city income taxes?

No. Idaho has no county, city, or local income taxes, and no state disability insurance tax. The only state-level wage tax is the flat 5.695% income tax, which keeps the Idaho side of a paycheck calculation relatively simple.

What taxes are taken out of an Idaho paycheck?

Federal income tax, Social Security at 6.2% up to the wage base, Medicare at 1.45% plus a high-earner surtax, and Idaho's flat 5.695% income tax. Pre-tax 401(k) contributions reduce the income subject to both federal and Idaho income tax.

How does the zero-bracket floor work?

Idaho's flat tax does not start at the first dollar. A floor of about $4,489 for single filers and $8,978 for joint filers is taxed at 0%, and only taxable income above that floor is taxed at 5.695%. The calculator applies this automatically after the standard deduction.

Will this match my actual Idaho paycheck?

It is a close estimate using 2024 federal and Idaho figures, standard deductions, and FICA. Your real check depends on your W-4 entries, health insurance and other pre-tax benefits, and any post-tax deductions, so treat the result as a planning figure.

Idaho keeps its state income tax simple: a single flat rate applies to taxable wages, with no local or disability taxes layered on. This calculator combines that flat rate with federal income tax and FICA to show what actually lands in your bank account each pay period.

How it works

The tool annualizes your pay, applies the standard deduction, and subtracts each tax. Idaho’s piece is a flat rate above a small floor:

Federal income tax using 2024 brackets after the standard deduction
Social Security at 6.2% up to the $168,600 wage base
Medicare at 1.45%, plus a 0.9% surtax above $200,000
Idaho income tax at a flat 5.695% on taxable income above the zero-bracket floor ($4,489 single, $8,978 joint)

Take-home = gross − federal tax − Social Security − Medicare − Idaho flat tax (5.695% above the floor).

Pre-tax 401(k) contributions lower the income subject to both federal and Idaho income tax, and the result is shown per check, monthly, and annually.

Example and notes

A single filer earning $2,600 bi-weekly grosses about $67,600 a year. After the standard deduction, Idaho’s flat 5.695% applies to the income above the floor; combined with federal tax and FICA, take-home lands near $2,000 per bi-weekly check.

Because Idaho has no local income tax and no state disability tax, the state side is just the one flat rate — simpler than most states. Your actual check depends on your W-4 and any pre-tax benefits, so use this as an estimate. Everything is computed in your browser; nothing is uploaded.
