Iowa Senate Advances Sweeping Property Tax Overhaul Bill

Des Moines, Iowa — A wide-ranging property tax and budget reform bill has cleared the Iowa Senate, setting the stage for significant changes to how local governments fund services and how homeowners are taxed.

Senate File 2472, approved April 8, 2026, includes major revisions to property tax limits, school funding formulas, and tax relief programs for homeowners and veterans.

At the core of the legislation are new limits on how much counties, cities, and other local entities can increase property tax revenues year over year. Beginning in fiscal year 2027, most local governments will be restricted to modest growth in property tax collections—generally tied to inflation or capped at roughly 1.5% to 2% increases, depending on the provision.

Lawmakers say the changes are intended to provide predictability for taxpayers while still allowing local governments to keep up with rising costs.

“This bill puts guardrails on property tax growth while still giving communities flexibility,” supporters argued during debate.

Changes for Homeowners and Taxpayers

The legislation also introduces a revamped homestead tax exemption system. Starting in 2026, most homeowners will receive a minimum exemption or a percentage-based reduction in taxable value, with significantly larger benefits available to older Iowans.

For example, homeowners aged 60 and older could qualify for exemptions covering up to 60% to 100% of their home’s taxable value, depending on age.

Disabled veterans and certain surviving family members would see even greater relief, with some qualifying for a full exemption from property taxes on their homes.

School Funding Overhaul

The bill makes a notable shift in school funding by increasing the state’s share of education costs. Beginning in the 2027 budget year, the state will cover 100% of the regular program foundation base per pupil—up from the current percentage.

This change is designed to reduce reliance on local property taxes to fund schools, a long-standing concern among taxpayers and policymakers.

New Limits on Local Borrowing

Another provision prohibits cities and counties from using bonds or other debt to pay for routine operating expenses starting in mid-2026.

Instead, borrowed funds must be used for long-term investments, a move aimed at improving fiscal discipline and preventing structural budget deficits.

Additional Measures

The bill also includes:

• Adjustments to agricultural and residential property assessments
• New limits on school district reserve funds and levy practices
• Changes to electric vehicle fees and fuel taxes, with annual inflation adjustments
• A study committee to examine long-term property tax rates statewide

What’s Next

Most provisions in the bill would take effect January 1, 2027, with implementation tied to fiscal years beginning July 1, 2027.

The legislation now moves forward in the lawmaking process, where it could face further revisions.

If enacted, Senate File 2472 would represent one of the most comprehensive overhauls of Iowa’s property tax system in years—impacting homeowners, local governments, and school districts across the state.
