RSU Tax Calculator for Iowa

RSU vesting in Iowa triggers a flat 3.8% state income tax, treated as ordinary income just like your salary. Your employer typically sells shares at vesting to cover the combined federal, state, and FICA withholding, which can consume 35-50% of the vested shares depending on your income level. This calculator shows you exactly how many shares (or dollars) you keep after all Iowa tax layers are applied.

Iowa levies a flat 3.8% state income tax on all taxable income regardless of how much you earn. This makes tax planning straightforward: for every additional dollar you earn, 3.8 cents goes to Iowa. Iowa does not impose local income taxes, so the 3.8% flat rate is the only state-level income tax you owe.

The table below shows what you actually keep at five salary levels in Iowa, accounting for federal tax, FICA, and Iowa's flat 3.8% state tax.
