Iowa school district surtax outside Des Moines (DMPS) is not yet wired into the calculator engine; the state-side numbers above use the engine's modeled schedule only.

Quick answer

A $100,000 salary in Iowa takes home about $75,992 per year. That works out to roughly $6,333 per month or $2,923 per bi-weekly paycheck for a single filer using the 2026 standard deduction, after federal tax, FICA, and Iowa's flat state income tax, with no pre-tax retirement contributions modeled.

Iowa's flat state rate applies uniformly to all income levels after recent reform. After the 2026 standard deduction, a single filer's taxable income reaches well into the federal 22% bracket on its top slice; the slices below are taxed at 10% and 12% for income above the standard deduction. Iowa transitioned from a progressive structure to a flat state rate in recent reforms. Many Iowa school districts levy a small income surtax computed as a percentage of state liability, which the calculator engine models in approximate form for Des Moines Public Schools but does not auto-apply for other districts. Des Moines (insurance and finance), Cedar Rapids (Rockwell Collins), and Iowa City (University of Iowa) anchor the state's wage base. Adjust salary, filing status, or pre-tax contributions in the calculator below to see how each lever moves take-home. Combined FICA of $7,650 layers above federal tax of $13,170 on the paycheck, with any state line stacking on top where applicable. The combined effective tax rate lands at 24.01%, reflecting all paycheck-side components (federal, state, FICA, plus any local layer) together before take-home arrives.

This estimate covers federal income tax owed at 2026 brackets after the standard deduction, FICA contributions (Social Security at the federal rate up to the annual wage base, Medicare on all wages, plus the Additional Medicare Tax above the filing-status threshold), state income tax computed from the state's bracket schedule, and local income tax where a city or county levies one. It excludes employer-side payroll taxes, custom W-4 withholding elections beyond the standard schedule, supplemental-wage handling for bonuses or equity vesting, and income from sources other than W-2 wages.

How much does a 401(k) or HSA contribution save on taxes at $100,000 in Iowa?

The doubled federal standard deduction plus wider MFJ brackets produce most of the lift, and the Additional Medicare 0.9% surtax sits well above $100,000 for every filing status; filing status doesn't move Iowa's flat-rate state line, which stays at 3.8%.
