Median effective rate = total real estate taxes paid ÷ total home value, for owner-occupied housing (2024 American Community Survey). YoY change is the inflation-adjusted change in taxes paid, 2023–2024. "N/A" indicates the Census Bureau's sample size was too small for a reliable county-level estimate.

Why is this an estimate and not my exact property tax bill?
Property tax in Iowa, like everywhere in the US, is calculated using your home's assessed value and the local mill rate set by your county, city, and school district — not a flat statewide percentage. Our estimator uses the county median effective rate (what a typical homeowner actually pays, relative to home value) to give you a reasonable estimate. Your actual bill depends on your specific assessment and any exemptions you qualify for.
