The Pro Sales Tax API connects an application with a database that offers sales tax data sourced from multiple public, private, and government institutions for accuracy. Sales tax information is offered by postal code, state, county or city. Pro Sales Tax charges on a monthly basis to access the API. Documentation is not publicly available. XML is the preferred delivery format.
