How Iowa paycheck tax works
Iowa has a flat income tax rate of 3.8% for 2026. Withholding subtracts a per-pay-period deduction that depends on filing status (biweekly: $500 single / $750 head of household / $1,000 married with a non-earning spouse), then applies 3.8%. Some Iowa school districts levy a surtax calculated as a percentage of state income tax.
Local tax can apply on top of the state's share. Some Iowa school districts add a surtax computed as a percentage of your state income tax; it is not included in the base state calculation.
The calculator annualizes your pay and applies Iowa'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. Local city, county, or school-district taxes aren't included in this figure.
