DES MOINES — Iowa’s sweeping 2026 property tax overhaul has been ranked No. 1 in the nation for reducing property tax burdens through a single piece of legislation during the past decade, according to a new analysis highlighted Thursday by Gov. Kim Reynolds.
The Common Sense Institute concluded that Iowa’s 2026 reforms produce the largest property tax reduction of any legislation enacted nationwide during that period, whether measured against statewide personal income or on a per-household basis.
The finding comes less than three months after Reynolds signed Iowa’s $4.2 billion property tax relief package into law.
According to the Institute, Iowa’s 2026 property tax reform is estimated to reduce the statewide property tax burden by approximately $1,463 per household during its first six years.
The organization also gave high marks to Iowa’s earlier 2023 property tax changes, estimating those reforms reduced the statewide burden by approximately $952 per household during their first six years.
“I’m proud that Republicans kept our promise to Iowans with this year’s property tax reform and created another $4.2 billion in tax savings over the next six years,” Reynolds said. “This report confirms that we’re not only delivering for our state but also leading the nation in meaningful tax relief for working families.”
The 2026 legislation, Senate File 2472, represented one of the major accomplishments of this year’s Iowa legislative session.
Mason City Republican state Rep. Christian Hermanson called the measure a “historic win for Iowa taxpayers” after lawmakers approved the legislation.
Among its provisions, the law expands property tax relief for homeowners through changes to Iowa’s homestead exemption, reduces the school foundation property tax levy over several years and increases the amount of statewide sales tax revenue directed toward property tax relief.
The legislation also retained existing exemptions for seniors and military veterans while increasing the elderly and disabled rental credit.
Property taxes had been one of Reynolds’ biggest priorities heading into the 2026 legislative session.
In January, Reynolds unveiled her original property tax reform proposal, arguing that property tax increases had been outpacing inflation, population growth and wages.
The package changed substantially as it worked its way through the Legislature, with the projected taxpayer savings eventually growing to approximately $4.2 billion over six years.
The Common Sense Institute said Iowa’s combination of its 2023 and 2026 reforms could substantially improve the state’s tax competitiveness.
The organization noted that Iowa had previously carried one of the heavier property tax burdens nationally, ranking 11th among states when property taxes were measured relative to statewide personal income.
The latest analysis suggests Iowa’s recent legislative changes could significantly alter that standing as the reforms are phased in.
For homeowners, however, the statewide projections do not necessarily mean every individual property owner will see a $1,463 reduction on a tax bill. Actual property taxes depend on assessments, exemptions, local government levies, school district taxes and other factors specific to each property and taxing jurisdiction.
The Institute’s $1,463 figure represents its estimated statewide reduction per household during the first six years of the 2026 reform.
