Iowa State Income Tax 2026 – Flat Rate System
Iowa modernized its tax code by replacing multiple brackets with a single low rate. For tax year 2026, the projected uniform rate is 3.9% applied to Iowa taxable income after the state’s standard deduction. No additional brackets, surtaxes, or local income taxes apply to employee wages.
| Rate | Taxable Income (Iowa) after Standard Deduction |
|---|---|
| 3.9% flat (projected 2026) | All Iowa taxable income above standard deduction |
Iowa Standard Deduction 2026 (projected): Single $2,600 | Married Filing Jointly $5,200 | Head of Household $3,900. Iowa follows federal adjusted gross income as a starting point; our calculator applies these deductions before calculating the flat 3.9% rate. There are no personal exemption phase‑outs or add‑back complexities for most wage earners.
How Federal + Iowa State Taxes Impact Your Paycheck
Your gross salary is reduced by: federal income tax (progressive brackets), Social Security (6.2% up to wage base of $181,000), Medicare (1.45% uncapped), and Iowa state income tax (flat 3.9% on taxable income). No local income taxes, no SDI, and no special payroll surcharges — making Iowa a tax‑predictable state for both traditional employees and remote workers.

Social Security (on $85,000) = $5,270, Medicare = $1,232. Total taxes ≈ $19,197 → net annual ≈ $65,803 ($5,484/month).
