In July of 2008, Washington state moved from origin to destination-based sales tax sourcing. That applies to everyone
Flower deliveries are exempt from the 2008 switch to destination-based sales tax in Washington
except florists. Certain florists may continue using origination to determine the sales and use tax due on a retail transaction, specifically when one florist takes an order and passes along that order to another florist who then delivers the flowers to the location designated by the customer.
Certain other sourcing exemptions apply to leases, rentals, and telecommunications services.
