Washington e-commerce nexus compliance support

For US business owners and LLC founders selling into Washington via e-commerce, understanding state-specific tax compliance is crucial. Washington requires businesses to register and report B&O tax and collect sales tax if they exceed $100,000 in combined gross receipts sourced to Washington in the current or prior calendar year (effective Jan. 1, 2020).

This threshold includes marketplace sales.Marketplace facilitators are generally responsible for collecting and remitting sales tax on facilitated sales, but sellers must still file excise tax returns to report B&O tax.

Registration is done through the Business License Application.Washington uses destination-based sourcing, meaning sales tax is collected at the rate applicable to the customer’s delivery location (state rate 6.5% plus local portions).

The state also imposes a Business & Occupation (B&O) tax, a gross receipts tax, which must be reported if the $100,000 threshold is met. Filing frequencies vary (monthly, quarterly, annual) with specific due dates.To ensure compliance, businesses should regularly monitor Washington receipts, register promptly if the threshold is approached, and configure e-commerce platforms for destination-based rates.
