About PropertyTaxAtlas
PropertyTaxAtlas is an independent data project that turns public U.S. Census Bureau property-tax data into a fast, free county reference and estimator. Every number is traceable to the American Community Survey, the method behind each figure is documented, and nothing on the site is sponsored or pay-to-rank. It exists because per-county property-tax information online is often shallow or simply wrong — including an incumbent that published an effective rate off by 100×.
What this site does
PropertyTaxAtlas turns one authoritative, public-domain source — the U.S. Census Bureau's American Community Survey — into a fast, free, per-county property-tax reference and estimator. For every U.S. county-equivalent it publishes the median real-estate taxes paid (with margins of error), the effective tax rate, state and national rank, tax as a share of income, and a nearby-county comparison, plus a live estimator for any home value.
Why it exists
Per-county property-tax information online is often shallow, ad-choked, or simply wrong — during research one thinly-sourced incumbent was found publishing a county's effective rate off by a factor of 100. Property tax is one of the largest recurring costs of owning a home and a real factor in where people buy, yet a trustworthy, arithmetic-correct, per-county reference is surprisingly hard to find. This project is the attempt to be that reference.
How it stays trustworthy
Every figure is traceable to a named Census table and vintage, and the methodology page documents each definition, the margins of error, how suppressed values are handled, and why “nearby” counties are computed by distance. Nothing on the site is sponsored, and no ranking is pay-to-play. Where the data does not support a claim — a suppressed median, a per-county assessor URL we cannot verify — the site says so rather than inventing a number.
Independence
This is an independent data project, not affiliated with the Census Bureau or any government agency, tax authority, lender, or brokerage. It presents public data with original analysis and makes no money from how any county ranks.
