Iowa Paycheck Calculator (2026)

How Iowa taxes income

A flat 3.80% applies at every income level in Iowa. There are no brackets to plan around — a raise is taxed at the same state rate as your first dollar, which makes the arithmetic unusually simple.

What actually reaches your account

Rough take-home at three common salary levels: $50,000 gross leaves roughly $39,275 after federal, FICA and $1,900 of Iowa tax; $80,000 gross leaves roughly $60,440 after federal, FICA and $3,040 of Iowa tax; $120,000 gross leaves roughly $87,060 after federal, FICA and $4,560 of Iowa tax. These use standard-deduction assumptions and no pre-tax contributions — a 401(k) or HSA lowers both federal and state tax and moves these numbers up.

Cost of living matters as much as the tax rate. Iowa runs about 10% below the national average, so $80,000 here has the purchasing power of roughly $88,889 at national-average prices. A lower-tax state with higher housing costs can leave you worse off in real terms.
