TaxJar API

TaxJar provides retailers with easy access to the information they need to file their sales tax returns for all counties and cities in the U.S. TaxJar provides access to its information through two APIs: the Smart Sales Tax API and the Sales Tax Rate API. The Smart Sales Tax API allows users to determine the amount of sales tax that should be withheld based on a shipment's origin and destination points. The Sales Tax Rate API allows users to retrieve the sales tax rate for a given location.
