The Iowa Senate has passed an amended property tax reform bill, Senate File 2472, in a 41-4 vote. The measure makes adjustments to the state's 'rollback' system for calculating property taxes, repeals a 2023 law setting levy rate caps, and includes other changes like maintaining the school foundation levy. However, substantial negotiations remain between the Senate, House, and Governor before a final bill is agreed to before the end of the legislative session.

Why it matters

Property tax reform has been a key priority for Iowa lawmakers, with competing proposals from the Senate, House, and Governor's office. The passage of this amended Senate bill signals progress, but also the need to reconcile differences between the chambers to enact meaningful changes to the state's property tax system.

The details

The initial Senate bill proposed eliminating Iowa's 'rollback' system for calculating property taxes, but the amended version makes adjustments to how residential, commercial and multi-residential properties are assessed under this system. The bill also repeals a 2023 law that set levy rate caps for cities and counties, instead setting a 'soft cap' on the levy system while excluding certain levies. Other changes include keeping some of the residential rollback, adding changes to tax-increment-financing (TIF), striking the senior unencumbered home exemption, maintaining the school foundation levy, and adding the First Home Account program.

  • The Iowa Senate passed the amended Senate File 2472 bill on April 17, 2026.
  • The final day of the Iowa legislators' per diem is April 21, 2026.
