Tax Data Service API

The service provides sales and use tax rates by location within the United States and Canada. A list of taxing jurisdictions with authority in a location may also be generated.

API methods accept submission of a five-digit U.S. ZIP code or an abbreviation specifying a Canadian province, then return current sales and use tax rates. If the submitted ZIP code or province matches multiple city/county combinations, multiple sets of data cover each of the taxing jurisdictions.
