County property tax dataset
For owner-occupied homes across 3,135 US counties, one CSV file gives median property tax bills, median home values, and effective tax rates. You can open the file in a spreadsheet.
Reuse is free under CC BY 4.0. A credit to property-tax-calculator.org and the Census American Community Survey is requested.
What the columns mean
| Column | Meaning |
|---|---|
| state | State name |
| county | County or county-equivalent name |
| county_fips | Five-digit county FIPS code |
| median_real_estate_tax_usd | The median amount owner-occupied homes paid in yearly real estate tax (table B25103) |
| median_home_value_usd | Median value of owner-occupied homes (table B25077) |
| effective_rate_pct | Median tax divided by median value, in percent |
| owner_occupied_homes | Owner-occupied homes in the county (table B25003) |
| tax_top_coded | Marked yes when a $10,000 Census cap applies to the median tax, since the true rate is then at least the value shown |
One row appears for each of the 3,135 counties in the file. These are the counties where Census publishes both median tax and median home value figures.
A look at five rows inside the file
| state | county | county_ | median_ | median_ | effective_ | owner_ | tax_ |
|---|---|---|---|---|---|---|---|
| Alabama | Autauga County | 01001 | 627 | 207200 | 0.30 | 17660 | no |
| Illinois | Hardin County | 17069 | 1001 | 103800 | 0.96 | 1229 | no |
| Michigan | Gladwin County | 26051 | 1867 | 162300 | 1.15 | 9710 | no |
| New York | Warren County | 36113 | 3936 | 267400 | 1.47 | 21731 | no |
| Tennessee | Tipton County | 47167 | 1211 | 240600 | 0.50 | 17294 | no |
These rows appear exactly as they are in the CSV file, and that file is sorted first by state, then by county.
Sources of the figures
All figures come from Census American Community Survey 5-year estimates covering 2020 to 2024, which combine five years of answers so small counties are included. The file draws on three Census tables:
- B25103 tableB25103 table: median real estate taxes paid
- B25077 tableB25077 table: median value of owner-occupied homes
- B25003 table: tenure (owner-occupied homes)
To find the effective rate, divide the median real estate tax by the median home value, multiply by 100, and round to two decimals. Autauga County, Alabama, appears in the first row above, and its $627 tax against a $207,200 home value equals 0.30%.
Each December the Census publishes its next ACS 5-year release, and the file is refreshed then. Because the download address does not change, any link to it continues to work.

What to know before using it
- Homeowners actually paid these amounts, rather than the legal tax rate. The effect of exemptions and assessment limits is already included.
- Every figure is an estimate drawn from a five-year survey, and each one carries a margin of error that is larger in small counties.
- For one home, the tax bill depends on that property's value and the taxing units that apply. It is estimated by the property tax calculator using this file.
