What is the idaho paycheck calculator — take-home pay?

In short

Idaho levies a flat 5.8% income tax, withheld from each paycheck on top of federal income tax and FICA. On a $75,000 salary, a single filer in Idaho takes home roughly $58,176 per year — about $2,238 per bi-weekly paycheck after $7,670 federal tax, $5,738 FICA, and $3,416 Idaho state tax.

This Idaho paycheck calculator estimates your net take-home pay for any pay frequency. It applies 2026 federal income tax brackets, full FICA withholding (6.2% Social Security + 1.45% Medicare), Idaho's state income tax (a flat 5.8% income tax), and pre-tax deductions such as 401(k) and HSA contributions. Idaho simplified its graduated tax structure to a single 5.8% flat rate in 2023.

How to use this calculator

  1. 1Enter your annual gross salary.
  2. 2Select your pay frequency (weekly, bi-weekly, semi-monthly, or monthly).
  3. 3Choose your filing status.
  4. 4Idaho is pre-selected as your state — change it to compare other states.
  5. 5Set your 401(k) rate and monthly HSA contribution if any.
  6. 6Read your per-paycheck take-home and the annual tax breakdown.

The formula

federal taxable=gross−pre-tax−std deduction
FICA=gross×6.2%+gross×1.45%
take-home=gross−federal tax−FICA−state tax−pre-tax
Take-home = gross pay − federal income tax − FICA (7.65%) − Idaho state tax − pre-tax deductions. Idaho state tax = taxable income × flat rate (5.8%).
gross
— Annual or per-period gross pay before deductions

federal tax
