Iowa property tax is set locally, not by the state. Your county assessor values your home, then applies a local millage (tax) rate. Cities, school districts, and special districts each add a share.
Because rates vary by county, this page uses the Iowa median effective rate of 1.39%. That is the median tax paid divided by the median home value, from the U.S. Census Bureau (ACS 2024). It is a benchmark, not your exact bill.

What exemptions can lower your Iowa property tax?
Most counties offer a homestead exemption on your primary home. Many add relief for seniors, veterans, and people with disabilities. These lower your taxable value, so your real rate is often below the median.
Rules and amounts vary by county and change over time. Check your county assessor for the exemptions you qualify for before relying on a figure.
Why is your actual Iowa bill different from this estimate?
Three things move your bill away from the state median. Your county rate may be higher or lower than the median. Your assessed value can lag the market. And exemptions reduce the taxable amount.
Use this page to budget and compare. For the exact number, use your latest assessment notice and your county's current millage rate.
