How it works
Enter your pay and what’s on your W-4 to see each paycheck after taxes in Iowa. Federal income tax is figured with the IRS percentage method for 2026, the same tables payroll software uses, plus Social Security (6.2%) and Medicare (1.45%).
Iowa subtracts $13,000 from yearly wages ($19,500 head of household, $26,000 married when your spouse has no earned income), withholds a flat 3.8% of the rest, and takes $40 off the tax for each allowance on your IA W-4.
Many Iowa school districts levy an income surtax, a percentage of the resident's Iowa income tax liability set per district by the Department of Management. It is settled on the annual return and is not part of the employer withholding formula; no 2026 rate list was collected.
Withholding is an estimate of your tax, paid as you go. Whether you get a refund depends on your full-year income, deductions and credits; the tax refund calculator estimates that. To compare states, use the paycheck calculator.
Formula
Take-home = gross pay − federal withholding − Social Security − Medicare − Iowa withholding − pre-tax deductions

Employers round to the cent or dollar, some benefits change which wages are taxed, and bonuses are often withheld at a flat supplemental rate. Social Security also stops for the year once your wages pass $184,500. Use your pay stub to check, and this page to see how a change would affect it.
