Unemployment Insurance (SUI)

Governor Kim Reynolds signed Senate File 607 on June 5, 2025, dramatically simplifying Iowa's UI tax structure. The result for 2026: a taxable wage base nearly cut in half, from $39,500 to $20,400, alongside a maximum employer rate cut from 9% to 5.4%. This is one of the most significant single-year SUI overhauls of any state this decade.

Update your payroll system's Iowa wage base immediately
Any payroll configuration still referencing Iowa's 2025 wage base of $39,500 will over-withhold SUI on every Iowa employee earning above $20,400 in 2026. Given the size of this change — among the largest of any state, any year — this is worth a dedicated verification pass rather than assuming a routine annual update.
