Building on the five principles of sound tax policy (fair, competitive, transparent, limited, and protective of freedom), two reforms rise to the top as the most effective way to deliver lasting property tax relief in Iowa. First, Iowa should adopt a local government spending cap that limits how fast property taxes can grow each year. Second, Iowa must overhaul its property tax transparency system and replace the current notice structure with a clear, Truth-in-Taxation model similar to Minnesota’s. Together, these reforms address both sides of the property tax problem: they restrain the spending that drives taxes up, and they give taxpayers the information they need to hold local governments accountable.
Any meaningful reform must begin by addressing the core problem driving high taxes: local government spending. Over the past 20 years, Iowa’s property taxes have increased by more than 107 percent, a direct result of rising local spending.
This is why adopting a fiscal rule or spending limitation at the local level is essential. As the late economist Milton Friedman said, “The thing you should keep your eye on is what government spends.” Economist Art Laffer reaches the same conclusion: “Government spending is taxation.” A 2 percent property tax cap would directly confront this reality by limiting how quickly local governments can increase property taxes each fiscal year. To be effective and fair, a cap must apply to the entire budget—no exempt levies, no inflation carveouts, and no exclusions that shift the burden from one group of taxpayers to another.
A cap must also apply to school districts. Although the state sets per-pupil funding levels, school districts still control major elements of their budgets. Ensuring schools operate within a 2 percent cap would align state and local decision-making, rein in spending growth, and provide taxpayers with consistent, across-the-board relief. This approach satisfies every aspect of sound tax policy: it treats taxpayers equally, improves economic competitiveness by lowering tax burdens, provides a transparent standard, limits government growth, and strengthens property rights and economic freedom.
The second reform needed to achieve meaningful property tax relief is a major overhaul of Iowa’s transparency requirements. The current “Direct Notification” law was intended to provide taxpayers with clear, personalized information about upcoming budgets and tax bills, along with notice of city, county, and school district budget hearings. In practice, the notices have fallen short: the forms are confusing, the data is often inaccurate, and many taxpayers struggle to understand how proposed spending increases affect their bills.
Iowa should replace the existing notification system with a proven Truth-in-Taxation model similar to the one used in Minnesota. Minnesota and Utah provide clear, accurate notices that break down projected tax changes by jurisdiction and tell taxpayers, in plain terms, how spending decisions will affect their bill. States using these notices consistently see higher public engagement and stronger accountability in local budgeting.
This reform would advance all five tax policy principles at once: it would enhance fairness by treating every taxpayer the same, improve competitiveness by discouraging spending growth, increase transparency, reinforce limits on government power, and protect taxpayer freedom by giving citizens real influence over tax decisions.
When a taxpayer opens their statement, they should immediately be able to see how new spending will affect their property tax bill. That clarity alone would deter unnecessary spending increases, shine sunlight on local governments’ budget decisions, and compel elected officials to justify their proposals directly to the public.
These solutions may appear straightforward, but they require political discipline. The most challenging task in any level of government is controlling spending, yet doing so is the only path to lasting, broad-based property tax relief. When paired with meaningful transparency, these reforms would honor Iowa’s five core tax policy principles—and give taxpayers the fair, simple, limited, and freedom-protecting property tax system they deserve.
