The formulas

  • Sales tax = sale x (6.5% + local rate)
  • Nexus when counted sales are more than $100,000 in the current or prior calendar year
  • Counted sales = direct sales + marketplace sales

How it works

Figures current as of November 2026.

The state rate is 6.5 percent. The tool multiplies the sale amount by the statewide base rate plus the local rate you enter (local sales tax for the delivery address) and shows the state and local parts separately. The local rate depends on where the goods are delivered.

A seller with no physical presence in Washington must register and collect once it has more than $100,000 of gross income of the business attributed to Washington in the current or prior calendar year. Sales you make through a marketplace facilitator count toward your own Washington threshold, together with your direct sales.

A seller with a physical presence in Washington, such as staff, an office or inventory, must collect regardless of the threshold. The tool does not decide whether a product is taxable or exempt; enter the taxable price.
