Frequently asked questions
Does Iowa have a state income tax?
Yes. Iowa uses a flat-rate income tax — currently 3.80% — meaning everyone pays the same percentage regardless of income level, unlike the federal system's tiered brackets. A raise doesn't push you into a higher state rate; it only affects your federal marginal rate.
What's the difference between gross pay and net pay?
Gross pay is your full salary or wages before anything is withheld. Net pay (take-home pay) is what actually lands in your bank account after federal income tax, Social Security, Medicare, and Iowa state tax are subtracted. The gap between the two is typically 20-35% of gross pay, depending on income level and filing status.
How are Social Security and Medicare tax calculated?
Social Security and Medicare together make up "FICA" tax. Social Security is withheld at 6.2% of gross pay up to an annual wage base cap ($184,500) — income above that isn't taxed for Social Security. Medicare is withheld at 1.45% with no cap, plus an extra 0.9% Additional Medicare Tax on income above $200,000 (single) or $250,000 (married filing jointly).
Why is this calculator free with no signup?
Because the math behind it is public — federal brackets, FICA rates, and Iowa's tax rules are all published by the IRS and state tax authorities. This tool runs the calculation in your browser; nothing you enter is sent to a server, stored, or requires an account.
