$90,000 After Taxes in Iowa (2026)

A single filer paid $90,000 in Iowa has $73,900 of federal taxable income after the $16,100 standard deduction. The top slice of that income falls in the 22% federal bracket, which starts at $50,400 of taxable income, and federal income tax comes to $10,970, or 12.19% of the salary.

Payroll tax is federal and the same in Iowa as everywhere else: on $90,000 of wages it is $6,885, made up of $5,580 of Social Security at 6.2% of every dollar and $1,305 of Medicare at 1.45%.

Iowa taxable income is $73,900, and Iowa taxes it at its flat 3.8% rate. State income tax is $2,768, after $40 of credits the state applies at this income, 3.08% of the salary. Iowa's individual income tax is a flat 3.8% for tax year 2025 and later, the final step of S.F. 2442 (2024).

Altogether $20,623 of a $90,000 Iowa salary goes to tax, an effective total rate of 22.91%, which leaves $69,377 a year: $5,781 a month, $2,668 every two weeks, $1,334 a week, or $33 an hour over 2,080 hours.

At $90,000, Iowa ranks 17th of 51 jurisdictions for take-home pay, highest first. A no-tax state leaves $2,768 more a year, and the median state $483 less than Iowa. The lowest take-home at $90,000 is $65,872, in Oregon, $3,505 less than in Iowa.

Across the state line the same $90,000 leaves a single filer: Minnesota $67,548, $1,828 less; Wisconsin $68,311, $1,066 less; Illinois $67,835, $1,542 less; Missouri $68,930, $447 less; Nebraska $68,930, $447 less; South Dakota $72,145, $2,768 more.

Some localities in Iowa levy their own income tax, and none of it is included in the $90,000 figures here; the local income tax pages explain how it works.

These Iowa figures treat the whole $90,000 as wages, take the standard deduction, claim no dependents and include no federal credits. A pre-tax 401(k) contribution or health premium would lower taxable income and raise take-home; a second income or itemized deductions would change it again.
