How Idaho paychecks are taxed in 2026
Your gross pay is reduced by four main taxes before it reaches your bank account:
- Federal income tax — withheld using the IRS percentage method and your W-4, across the 10%–37% brackets.
- Social Security — 6.2% of wages up to the annual wage base.
- Medicare — 1.45% of all wages, plus 0.9% extra on wages over $200,000.
- Idaho state income tax — a flat 5.30% on taxable income, with no local city income taxes in Idaho.
How overtime is calculated
Under the Fair Labor Standards Act, non-exempt hourly employees in Idaho earn overtime at 1.5× their regular rate for hours worked beyond 40 in a workweek. Enter your overtime hours and this Idaho overtime calculator adds that premium pay to your gross, then taxes the total — overtime is taxed the same as regular wages, it’s just a higher amount.
Hourly to salary, and every pay frequency
Switch between hourly and salary at the top. The calculator annualizes your earnings and shows take-home pay for every common Idaho pay schedule — weekly, bi-weekly, semi-monthly, monthly and yearly — so you can compare paychecks no matter how your employer pays you.
Lower your Idaho tax withholding
Pre-tax contributions reduce your taxable income. Adding to a 401(k), HSA or pre-tax health premiums lowers the federal and Idaho income tax you owe (401(k) contributions still pay Social Security and Medicare). Try raising the 401(k) percentage to see your take-home change in real time.
Idaho paycheck calculator — frequently asked questions
Does Idaho have a state income tax?
Yes. Idaho has a flat state income tax of 5.30% on taxable income for 2026. There are no separate city or county income taxes in Idaho, so the state rate is all you pay at the local level.
How do I calculate my Idaho hourly paycheck?
Multiply your hourly rate by hours worked, add overtime at 1.5×, then subtract federal income tax, Social Security (6.2%), Medicare (1.45%) and Idaho income tax (5.30%). This calculator does all of that automatically — just enter your rate, hours and overtime.
How is overtime taxed in Idaho?
Overtime pay is taxed exactly like regular wages. There’s no special overtime tax — it can feel like more is withheld only because the larger paycheck can briefly push you into a higher withholding tier for that period.
What is the Idaho income tax rate for 2026?
Idaho uses a flat 5.30% income tax rate. It applies to taxable income above a small zero-tax threshold after the standard deduction, which Idaho matches to the federal standard deduction.
How much is taken out of a paycheck in Idaho?
For a typical worker, expect roughly 18%–28% of gross pay to go to federal income tax, Social Security, Medicare and Idaho’s 5.30% state tax combined — the exact amount depends on your income, filing status, dependents and pre-tax deductions. Use the calculator above for your specific numbers.
