TALLIVOIowa Paycheck Calculator
Your 2026 take-home pay in Iowa, after federal income tax, Social Security, Medicare, and state income tax.
On Iowa's median household income of $85,480, a single filer takes home $66,329 a year — $5,527 a month — after $9,976 in federal income tax, $6,539 in Social Security and Medicare, and $2,636 in Iowa income tax.
That is an effective all-in rate of 22.4% for 2026 federal rules and 2026 Iowa rules, taxes only — no 401(k), health premiums, or other deductions. Your own figure depends on filing status and pre-tax contributions.
Paycheck taxes in Iowa
Iowa moved to a flat 3.8% individual income tax starting tax year 2025, down from a 5.7% top rate in 2024. Iowa taxable income starts from federal taxable income, so the federal standard deduction is effectively built in (approximated here). Retirement income is fully excluded for taxpayers 55 and older, and many localities levy school-district surtaxes not included in this estimate.
Bonuses and supplemental wages in Iowa
Bonuses and other supplemental wages are frequently withheld differently from regular pay, and states set their own rules. This calculator applies Iowa's regular withholding to every dollar and does not model a separate supplemental rate, so a bonus paycheck can come out higher or lower than the figure above. Federal supplemental withholding is a flat 22% up to $1 million; for Iowa's own treatment, check the state authority linked below.
For the federal half, which this site does model, compare what withholding takes from a bonus against what you actually owe — the 22% flat rate is withholding, not a tax bill, and the difference comes back at filing.
Iowa vs. its neighbors
On a $100,000 salary you keep $75,992 in Iowa — $1,617 more than in neighboring Illinois, $731 more than in Wisconsin, and $575 more than in Missouri.
Federal income tax and FICA are identical in every state, so the whole gap above is state income tax. Single filer, $100,000 of wages, no 401(k) or other pre-tax deductions, 2025 state tables. Local income taxes (city and county) are not included. Run your own salary through the calculator above, or on any state's page.
Neighbours are only part of the picture. The study behind these figures ranks what a $100,000 salary takes home in all 50 states, with Iowa's row in place — the entire spread between best and worst is state income tax, since federal tax and FICA are identical everywhere.

How we calculate this
Federal brackets and FICA per our paycheck methodology, plus Iowa's 2026 state income tax. Estimates only — not tax advice.
Estimates for general informational purposes only; not tax or financial advice. State rules, local taxes, and credits vary — Iowa figures are simplified and should be verified with the state Department of Revenue. Actual withholding depends on your W-4 and benefits. Iowa's flat 3.8% is applied with the $16,100 standard deduction for a single filer — not itemized deductions or any Iowa tax credit. It also excludes any local, county, or school-district tax your municipality may add.
