Trigger present

B&O tax

Likely subject to B&O tax

Substantial nexus is established by Washington receipts above the $100,000 substantial-nexus threshold (RCW 82.04.067). B&O tax applies to your gross Washington receipts under the classification(s) below — there is no income-tax-style profit threshold.

Retail sales / use tax

Likely required to collect sales tax

Retail sales of goods or digital products delivered into Washington require collecting retail sales tax at the rate of the delivery location (destination-based sourcing), filing, and remitting.

Registration and classification

Washington registration

Registration is required: businesses doing business in Washington must register once gross income reaches $12,000 per year or any sales tax collection obligation exists. Apply through the Business Licensing Service (business license application) — city license endorsements can usually be added on the same application.

Potential B&O classifications

Retailing

0.471% of gross retail sales (rises to 0.5% on Jan 1, 2027 under ESHB 2081).

City and local review

Cities license separately from the state: about 50 Washington cities (Seattle, Tacoma, Bellevue, Everett, and others) impose their own B&O tax with their own nexus standards and thresholds, filed through FileLocal or the city directly. Check every city where you have employees, property, or meaningful sales.

Trailing nexus: once established, substantial nexus continues through the end of the calendar year AFTER the year your nexus-creating activity stops (RCW 82.04.067(1); RCW 82.04.220(2)(b)) — obligations don't end the day you pull out of the state.
