How Idaho paycheck tax works
Idaho has a flat income tax rate of 5.3% for 2026. Withholding uses a zero-tax bracket on the first $15,000 of wages for single filers ($30,000 married), then applies 5.3% to the excess. The flat 5.3% rate also applies to supplemental wages.
The calculator annualizes your pay and applies Idaho's 2026 flat-rate withholding on top of federal income tax and FICA. Treat the result as a close estimate; your employer may withhold from per-period tables that differ slightly.
