Data pending verification

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 pairs a flat state rate with school-district surtaxes in many districts (modeled in the engine for DMPS only). The marginal federal rate for a single filer here is 22%, and it applies only to the last slice of taxable income, not to the salary as a whole. The 24% bracket begins at $121,800, which is $21,800 of gross pay away. 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.

What this estimate includes

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. The bi-weekly take-home figure assumes a 26-paycheck schedule.
