How Iowa Paychecks Work

Iowa now uses a flat individual income tax rate rather than a multi-bracket system. For 2026, the flat tax rate is 3.8%, which applies to all taxable individual income.

Iowa withholding can include standard deduction rules and certain credits or allowances, so the exact paycheck amount can vary based on filing status and the information entered on your IA W-4.

Pre-tax deductions such as a 401(k), health insurance, HSA, or FSA can reduce taxable wages for federal calculations and may also affect your Iowa paycheck estimate.
