Iowa
Iowa paycheck calculator
Iowa taxes wages at a flat 3.8%. The model starts from a $16,100 single standard deduction and a $40 exemption credit. Some cities or counties can add a local wage tax; this page leaves them off until you select one. Federal brackets and FICA are unchanged by the flat state rate.
A traditional 401(k) reduces the state wage base here; it does not reduce Social Security or Medicare. No state disability or paid-leave premium is modeled for employees here yet. Flat tax conversion is in effect. A small exemption credit ($40 / $80) is subtracted.
The example table on this page is a single filer, biweekly, with no deductions, for tax year 2026. It is an educational estimate, not an employer payroll register or a filed return. Compare another state with the same salary when an offer crosses a border.
