Washington State is a <a href="http://dor.wa.gov/Content/FindTaxesAndRates/RetailSalesTax/DestinationBased/MoreSST.aspx" rel="nofollow ugc">destination-based sales tax</a> state.

When selling digital goods, the billing address is use to calculate tax.
Most e-commerce platforms have relatively rudimentary tax calculation tools and tables. <a href="https://shopplugin.net/" rel="nofollow ugc">Shopp</a>, while robust, doesn’t have the ability to calculate the actual sales tax in Washington State based on destination address and zip.
