How Iowa taxes your paycheck
Iowa taxes wages at a flat 3.8% after a standard deduction of $16,100 (single) / $32,200 (married). Some Iowa cities or counties add a local income tax; enter that rate in the calculator if it applies to you. Some school districts add an income surtax.
Federal deductions are the same everywhere: income tax on earnings above the $16,100 standard deduction (single) using the 2026 brackets, 6.2% Social Security on the first $184,500, and 1.45% Medicare on everything.
