Editorial and corrections policy

A sales tax rate looks like a small number, but it is applied to every purchase a household or a shop makes, and a property tax estimate can decide whether a home is affordable. This page says where our figures come from and how we fix one that is wrong.

Who is responsible

Content and calculations: Radif Partners, contact@taxratesbystate.com.

Sources we use

• the department of revenue, taxation or finance (or the comptroller) of each state and of the District of Columbia: rate pages, publications, bulletins and holiday notices;
• state statutes and legislative sites, when a rate or an exemption is set by law and the department page is silent;
• county assessor and state property tax divisions for assessment rules and homestead exemptions;
• the U.S. Census Bureau (American Community Survey) for median property taxes and home values.

Sources we do not use

Rate tables published by sales tax software vendors, think tanks, media and other calculators can guide a search, never a figure. When one of them disagrees with a state page, the state page wins and the data file records the official address.

Review cycle

Every state is re-read at least every 12 months, before the January 1 and July 1 effective dates, and before each summer holiday season. Census figures are replaced when a new American Community Survey year is published.

Corrections

1. We check the report against the official page.
2. We fix the data file or the engine and add a test for the case.
3. The state page shows its new reading date.

Independence

No retailer, software vendor, lender or adviser pays to appear here. If that ever changed, it would be written next to the link.
