How Iowa taxes your paycheck in 2026
Iowa taxes wages at a flat 3.8%, after a $16,100 single-filer standard deduction (the state uses the federal deduction).
Federal deductions are the same everywhere: income tax on your wages after the $16,100 standard deduction (single filers), 6.2% Social Security on the first $184,500 of wages, and 1.45% Medicare on everything.
Iowa's income tax, in context
Iowa completed one of the fastest tax overhauls in the country: from a nine-bracket system topping out near 9% in 2018 to a single 3.8% flat rate in 2025. The state starts from federal taxable income, exempts retirement income entirely, and has eliminated its inheritance tax — a deliberate bid to keep retirees and remote workers from leaving.
