How Iowa taxes your paycheck in 2026
Iowa replaced its old nine-bracket system with a single 3.8% flat tax, fully effective in 2025 and continuing in 2026. Iowa now uses the federal standard deduction as its starting point, so the same deduction that lowers your federal tax also lowers your Iowa tax — a clean, simple system administered by the Iowa Department of Revenue.
| Gross salary | IA state tax (≈3.8%) | Est. take-home |
|---|---|---|
| $50,000 | ~$1,288 | ~$41,067 |
| $65,000 | ~$1,858 | ~$52,549 |
| $100,000 | ~$3,188 | ~$75,992 |
| $150,000 | ~$5,088 | ~$108,703 |

The 3.8% flat rate on federal taxable income
Because Iowa conforms to the federal standard deduction ($16,100 single / $32,200 married for 2026), a single filer earning $65,000 pays 3.8% on roughly $48,900 of income. The flat rate makes withholding predictable across all income levels.
