Zach Lahn and Governor Kim Reynolds seek to eliminate Iowa's state income tax through a proposed constitutional amendment.

Zach Lahn and Governor Kim Reynolds are pushing for a constitutional amendment to eliminate Iowa's state income tax, shifting the primary tax burden to sales and property taxes. The administration announced that the proposed change aims to create a more pro-growth tax code, though critics argue it primarily benefits the wealthy. Under the new amendment, raising the sales tax would require only a simple majority in the Legislature, while increasing income or corporate taxes would require a two-thirds super-majority. This structure makes it significantly easier for the state to raise sales taxes during budget crises. While Republicans argue this move fosters growth, the Missouri Budget Project and other analysts suggest that removing the income tax will inevitably lead to higher sales taxes for the average household. For middle-class and lower-income residents, this shift may be more taxing than for high earners. Supporters of the plan argue it protects the state from future income tax hikes, while opponents warn that it favors special interests who wish to preserve current tax breaks for the rich.
