What does Washington State’s Marketplace Fairness law mean for my business?


You want to know what Washington State's Marketplace Fairness law (effective January 1, 2018) means for your business.




Washington State requires sales tax collection and remittance for online marketplaces that include marketplace facilitators, remote sellers, and referrers (such as Amazon or Etsy). See the Department of Revenue site for more information. If your company does not use any marketplace facilitators, no action is needed.

NOTE: Currently, Amazon, Etsy and Walmart remit sales tax directly to Washington State. By using these location codes,  Avalara will not remit taxes for you because we know your taxes are being remitted by these particular marketplace vendors.

If your business uses an online marketplace, see the steps below for guidance on how to identify and report impacted transactions:

  • Create a location code for each marketplace facilitator, allowing you to identify and report the related transactions for this entity. 
  • Assign the new location codes to transactions to report correctly. 
  • Tips:
    • Use your Marketplace Facilitator Name for the Location Code. Note that location codes are case sensitive. For example:
      • Etsy
      • Amazon
      • Walmart
    • Use Marketplace for the Location Description 
    • Use Location for the type of Location 
    • Use Other for the Category 
    • Enter your business address in the Address Information fields
