County Property Tax Lookup
Type a county or partial name (e.g. "Cook", "Los Angeles", "Harris") to find its detail page. Searches all 3,000+ U.S. counties with Census ACS 2024 property-tax data.
How to Read County Data
Each county detail page shows the median annual property tax, the median home value, and the effective tax rate (the median tax expressed as a percentage of home value). The effective rate is the most useful comparison metric across counties because it normalizes for differences in home prices — a county with a low median tax in dollar terms can still have a high effective rate if home values are also low.
Why Counties Differ Even Within the Same State
Property-tax rates vary at the county and municipal level because each jurisdiction sets its own millage. Two counties in the same state can differ by 2-3x because of school-district funding, special assessments, county-level services, and the ratio of commercial to residential tax base. Rural counties with smaller commercial bases often shift more of the burden to residential property; urban counties with strong commercial corridors can offer lower residential effective rates.
Coverage
Lookup covers all U.S. counties (and equivalent jurisdictions: parishes in Louisiana, boroughs and census areas in Alaska, and independent cities in Virginia). Data is from the Census Bureau American Community Survey 5-Year Estimates, which combines five years of household responses for statistical reliability at small geographies. Some sparsely-populated counties may have suppressed values in the underlying ACS release.
