Property tax data sources
Every statewide figure in the calculators traces to one of the 602 primary sources listed below. Each state page repeats its own sources with the exact passage that states the figure.

State and District rule sources
Accepted sources are statutes and constitutions published by legislatures, state revenue or tax-commission pages, bulletins and forms, and the District’s Office of Tax and Revenue. Where a figure is set locally, no source is cited for a number because the calculator asks you for it. The verification policy is in the editorial policy.
Census context figures
The Census context on each page uses the 2024 American Community Survey five-year release, covering 2020–2024: table B25077 (median value of owner-occupied housing units) and table B25103 (median real-estate taxes paid). State and District rows, estimates and margins of error were read from the official table-based summary files; the downloaded files’ SHA-256 hashes are recorded in the data file.
- B25077 summary file — estimate E001 and margin M001
- B25103 summary file — estimate E001 and margin M001
Transfer tax sources
The separate transfer-tax calculators cite their own statutes: Georgia, Michigan, Illinois, Kentucky, Delaware, New Hampshire, South Carolina, Vermont, Colorado.
