All figures and charts show 2024 tax law in Iowa, presented at 2023 income levels. Senior taxpayers are excluded for reasons detailed in the methodology. Our analysis includes nearly all (99.9 percent) state and local tax revenue collected in Iowa. These figures depict Iowa’s 2024 graduated personal income tax, with a top rate of 5.7 percent, along with a top corporate income tax rate of 7.1 percent. By 2027, the income tax will reach a flat rate of 3.9 percent and the top corporate rate will be reduced to 5.5 percent. As seen in Appendix E, this will decrease the overall tax rate paid by the top 1 percent of households by 1.3 percentage points and cause the state to move 7 spots in the ITEP Inequality Index rankings, from 23rd to 16th most regressive.
