Iowa Income Tax Overview

Iowa reformed its income tax system and now has a flat rate of 3.8% for 2026, down significantly from what was previously a multi-bracket system with rates up to 8.53%. Iowa's flat rate mirrors the federal standard deduction ($16,100 for single filers), making the standard deduction one of the most generous in the country at the state level. Iowa is continuing to phase down its rate — the long-term target is 3.9% (which it already hit ahead of schedule). Iowa has no local city income taxes. Compared to neighboring Wisconsin (up to 7.65%) and Illinois (4.95% flat), Iowa's 3.8% flat rate is meaningfully more favorable. Minnesota to the north charges up to 9.85%, making Iowa a relatively attractive option for workers near the border.
