Washington excise tax rules on interstate sales and the collection of use tax are updated to reflect the U.S. Supreme Court’s decision in South Dakota v. Wayfair.
Economic Nexus Standard
In response to the Wayfair decision, the Department of Revenue requires remote sellers to collect sales or use tax on taxable sales sourced to Washington if it exceeds $100,000 in gross retail sales or 200 retail transactions in the state in the current or prior calendar year. The department has amended the rules on interstate sales and the collection of use tax in order to warn taxpayers that the rules may contain outdated guidance. Taxpayers are directed to consult the department’s website for current information on tax collection responsibilities.
Subscribers can view the amended rules.
