Idaho Paycheck Calculator (2026)
See take-home pay for any salary in Idaho for 2026. Enter an amount, or pick a common salary from the list to get federal tax, FICA, and Idaho state tax broken out in full.
Idaho taxes wages at a single rate of 5.3%, but only above a no-tax floor: income below a set threshold is exempt, and everything above it is taxed at 5.3%. Idaho starts from federal taxable income and uses the federal standard deduction, so the same deduction you claim federally reduces your Idaho base before the rate applies. There is no state personal exemption here, though Idaho offers a separate grocery credit. No employee-paid disability or paid-leave premiums are withheld, and there are no local income taxes. This page serves Idaho workers estimating take-home; the tables below show pay across salary levels for 2026 after federal tax, FICA and Idaho tax.

Frequently asked questions
How is take-home pay calculated in Idaho?
We start with your gross salary and subtract the 2026 federal standard deduction for your filing status, then apply the federal tax brackets to what is left. FICA, the Social Security and Medicare tax, is added on the gross. On top of that comes the Idaho state layer, using Idaho's own brackets or flat rate and its deductions. The result is your estimated annual tax liability, which we divide across your pay periods to show weekly, biweekly, and monthly figures.
Does Idaho tax bonuses differently?
A bonus is withheld using supplemental wage rules, which can differ from your regular paycheck. See the Idaho bonus tax page for how the federal flat rate and the state layer apply.
Are these numbers withholding or final tax?
These are an annual tax-liability estimate, not the exact withholding from any one paycheck. The per-paycheck columns are the annual figure divided by the number of pay periods. Your employer's real withholding uses IRS payroll tables and can differ slightly, then reconciles when you file your return.
