Businesses outside of Washington
If your business earns income attributable to Washington that would be taxable under an apportionable B&O classification and your business is organized or commercially domiciled in Washington or met one of the following thresholds during the prior calendar year, you have economic nexus with Washington:
- More than $53,000 of payroll in Washington
- More than $53,000 of property in Washington
- More than $267,000 of gross receipts from Washington
- from apportionable or wholesaling activities; or
- At least 25 percent of your total property, payroll, or receipts in/from Washington.
If you have economic nexus, you must register your business with the Washington State Department of Revenue and report and pay Washington B&O tax.
Note: In determining whether your business meets the gross receipts thresholds, you must also include receipts from wholesale sales sourced to Washington.
These thresholds are effective for periods starting in 2015. Please use these figures until revised. See Excise Tax Advisory (ETA) 3195.2016 for prior years.

Economic Nexus - Apportionable Income
Effective June 1, 2010, an “economic nexus” standard rather than a “physical presence” standard was created with regard to certain activities. It requires some businesses earning “apportionable income” (including activities subject to the service and other activities and royalty B&O tax classifications) from Washington customers to be subject to taxes whether or not they maintain offices in the state or have any physical presence.
Effective September 1, 2015, the time frame for determining whether a business has exceeded the payroll, property, and gross receipts economic nexus thresholds changes from the current tax year to the immediately preceding tax year. Part II of ESSB 6138.
