OLYMPIA – Jan. 3, 2011 – The Department of Revenue has improved the online tool that helps retailers find sales tax rates across the state.

The enhanced Find a sales tax rate system at http://dor.wa.gov also helps ensure that local governments receive sales tax when products are shipped or delivered to customers in their jurisdictions.

The GIS (geographic information system) provides location codes and tax rates through:

  • Address searches,
  • Improved maps, or
  • Latitude and longitude when an official post office address has not yet been created.

One challenge in identifying addresses has been inconsistencies between how the U.S. Postal Service lists an address and how users might input that address. By using multiple data sources, the updated system is better able to return a result.

“We’re now delivering a richer user experience, including adding aerial imagery overlays to better identify jurisdictions and appropriate tax rates, so users get the information they need when they need it,” said Revenue Director Suzan DelBene.

Washington uses a destination-based sourcing system, meaning sellers must charge sales tax according to where a product is delivered, not where it originated.
