Income tax in Iowa
Iowa taxes wage income on a progressive schedule — 1 brackets running from 3.8% to 3.8% for single filers. This calculator applies Iowa's real 2026 brackets, its standard deduction ($16,100 single / $32,200 married) and its personal exemption, so the state-tax line follows the actual schedule rather than a flat-rate guess.
Iowa income tax brackets for 2026
Single filers. Each rate applies only to the income falling inside that band — these are marginal rates, not a flat rate on the whole salary.
| Taxable income over | Rate |
|---|---|
| $0 | 3.8% |
State taxable income is your pay after Iowa's standard deduction and personal exemption of $16,100 for a single filer ($32,200 married filing jointly).
How Iowa compares

Worked example: $100,000 in Iowa
Take a single filer on $100,000 in Iowa. After the $16,100 standard deduction and personal exemption, state taxable income is $83,900:
| Income band | Rate | Tax |
|---|---|---|
| $0 – $83,900 | 3.8% | $3,188 |
| Total state tax | — | $3,188 |
The effective rate works out to 3.2% of gross salary — far below the 3.8% top marginal rate, because only the last slice of income is taxed at that rate.

Why does my actual paycheck differ from this estimate?
Real paychecks reflect your W-4 withholding choices and pre-tax benefits. For Iowa, some cities and counties levy a local income tax on top of the state rate, which this calculator does not include — use the local tax field above. This calculator is a planning estimate, not a payroll prediction.
