How Idaho taxes your paycheck
Idaho levies a flat 5.8% state income tax on taxable income above approximately $4,489 (single) after replacing its progressive brackets in 2023 with a single-rate system funded by state budget surpluses.
Idaho has no city or county income taxes, and the state offers a grocery tax credit that partially offsets the 6% state sales tax applied to food—one of only a few states that taxes groceries at the full rate but provides a refundable credit.
Why this matters: Idaho transitioned to a flat tax in 2023 through House Bill 1, eliminating its previous four-bracket progressive system and using surplus revenue to fund the rate cut and a one-time tax rebate to residents.

Last reviewed: February 9, 2026
How we calculate
- Estimate federal income tax from the 2026 progressive bracket model with the standard deduction baseline.
- Estimate FICA as Social Security (6.2% to the wage base) plus Medicare (1.45% with no cap).
- Estimate Idaho state tax from a flat 5.8% rate.
Assumptions
- Single-filer standard deduction baseline is used for planning.
- State tax modeling is simplified and does not replace a full state-form simulation.
- Results are annualized and converted to monthly and biweekly net pay.
Limitations

- Actual payroll withholding can differ by employer payroll setup and pay frequency.
- Use payroll records or a tax professional for filing-level accuracy.
