Standard deduction and exemption in Iowa
The 2026 standard deduction is $16,100 for single filers and $32,200 for married filing jointly. In Iowa, that means the first $16,100 of a single filer's pay is taxed at zero before the schedule even starts.
Worked example: the brackets on a $75,000 salary
A single filer earning $75,000 in Iowa first removes the standard deduction, leaving $58,900 of taxable income. Each bracket then takes its slice:
| Bracket range | Income in bracket | Rate | Tax |
|---|---|---|---|
| $0 and up | $58,900 | 3.8% | $2,238 |
Total Iowa income tax: $2,238, an effective rate of 2.98% of gross pay. The marginal rate, the rate on the next dollar Iowa taxes, is 3.8%; a raise that crosses into that bracket pays 3.8% only on the dollars above the line, never on the whole salary.

How Iowa compares with other states
How Iowa compares: on a $75,000 salary, the $2,238 a single filer pays ranks 36th highest among the 42 states and districts that tax wages in 2026, just behind Mississippi at $2,268 and just ahead of Rhode Island at $2,196.
A flat rate makes the marginal math unusually clean: every extra $1,000 of taxable income in Iowa adds exactly $38 of tax, no matter which end of the pay scale it lands on. A single filer's Iowa tax bill passes $1,000 at a gross salary of about $42,416, once the standard deduction has done its work.
