When you have to collect Washington sales tax
A remote seller has to register and collect Washington sales tax once its sales into the state meet the economic nexus threshold: $100,000 in sales in the current or previous calendar year, per the state tax agency. A physical presence such as an office, employees or inventory creates nexus on its own. The Washington sales tax guide covers registration and filing once you do.
