Compare Property Tax Rates by County Across the United States

TaxByCounty provides free, detailed property tax data for every county in the United States. Whether you are buying a home, relocating for work, or simply curious about how your county stacks up, our tools make it easy to look up effective property tax rates, median annual tax bills, and median home values for more than 3,143 counties across all 50 states and the District of Columbia.

All data comes directly from the U.S. Census Bureau American Community Survey (ACS) 5-Year Estimates, one of the most comprehensive and reliable public data sources on housing costs in America. Effective tax rates are derived by dividing median real estate taxes paid by median home value, giving you a clear, apples-to-apples comparison no matter which county you are evaluating.

Use our property tax calculator to estimate your annual tax bill based on your home's value and a specific county's rate. Compare rates across counties to find affordable areas, see how your current county ranks within your state, and explore side-by-side breakdowns of taxes with and without a mortgage. Every county page includes contextual data stories, state and national comparisons, and links to neighboring counties so you can make informed decisions about where to live and invest.
