$30,000 After Taxes in Iowa (2026)

A single filer paid $30,000 in Iowa has $13,900 of federal taxable income after the $16,100 standard deduction. The top slice of that income falls in the 12% federal bracket, which starts at $12,400 of taxable income, and federal income tax comes to $1,420, or 4.73% of the salary.

Payroll tax is federal and the same in Iowa as everywhere else: on $30,000 of wages it is $2,295, made up of $1,860 of Social Security at 6.2% of every dollar and $435 of Medicare at 1.45%.

Iowa taxable income is $13,900, and Iowa taxes it at its flat 3.8% rate. State income tax is $488, after $40 of credits the state applies at this income, 1.63% 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 $4,203 of a $30,000 Iowa salary goes to tax, an effective total rate of 14.01%, which leaves $25,797 a year: $2,150 a month, $992 every two weeks, $496 a week, or $12 an hour over 2,080 hours.

At $30,000, Iowa ranks 20th of 51 jurisdictions for take-home pay, highest first. A no-tax state leaves $488 more a year, and the median state $73 less than Iowa. The lowest take-home at $30,000 is $24,621, in Oregon, $1,176 less than in Iowa.

Across the state line the same $30,000 leaves a single filer: Minnesota $25,499, $298 less; Wisconsin $25,694, $103 less; Illinois $24,945, $852 less; Missouri $25,829, $32 more; Nebraska $25,762, $35 less; South Dakota $26,285, $488 more.

Some localities in Iowa levy their own income tax, and none of it is included in the $30,000 figures here; the local income tax pages explain how it works.

These Iowa figures treat the whole $30,000 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.
