Tax reform continues to be a top priority for the Republican trifecta. In 2022, legislation was passed that gradually phases down the state income tax until a flat tax of 3.9% is reached, as well as lowering the corporate income tax to 5.5%. In 2023, focus shifted from income tax to addressing property taxes.
During the Condition of the State, Governor Reynolds unveiled a proposal to accelerate the 2022 law by phasing down the individual income taxes to a flat rate of 3.5% by TY25. The Senate introduced a separate tax proposal in January that would gradually eliminate income taxes entirely by directing Iowa Public Employees' Retirement System (IPERS) to invest the Tax Payer Relief Fund into a trust with the revenues generated there used to buy down the individual tax rate.
Senate File 2442 was agreed upon in the final weeks of session and includes both individual and property tax changes. The final compromise accelerates the phase-down from the 2022 legislation to create a flat individual income tax rate of 3.8% for TY25, a summary of the current rates versus the new rates can be found in the table below.
The legislature also took the first steps toward amending Iowa’s Constitution related to income tax. Two resolutions passed both chambers requiring a two-thirds majority approval for future legislators to raise individual income taxes and requires Iowa use a flat tax rate system. The legislature must adopt the same language during the next legislative session for the proposed amendments to be considered by the public for ratification.
