1. Who needs a sales tax permit in Washington?
From the Washington State Department of Revenue website:

  • Generally, a retail sale is the sale of tangible personal property. It is also the sale of services such as installation, repair, cleaning, altering, improving, construction, and decorating. Other services include improving real or personal property, amusement and recreational activities, lawn maintenance, and physical fitness activities.
  • Retail sales tax includes the state and local components of the tax.
  • Sales tax amounts collected are considered trust funds and must be remitted to the Department of Revenue.
  • The seller is liable to the Department of Revenue for sales tax, whether or not it is collected.
  • Use tax is paid by the consumer when the retail sales tax was not collected by the seller/service provider.
  • Businesses that make a purchase for resale must provide a reseller permit to the seller. If not, the seller must charge the buyer retail sales tax on the total purchase.
  • Businesses also pay the retail sales tax on purchases of items for their own use (such as supplies or equipment) that will not be resold in the regular course of business.

Similarly, when a business purchases a retailing service for its own use, it must pay sales tax on the purchase.

Amazon announced that on January 1, 2018 they will begin collecting Washington sales tax on behalf of 3rd party sellers who sell on the Amazon platform. While this means that Amazon will collect and remit sales tax, Amazon FBA sellers with nexus in the state of Washington (See #1 above) will still be required to hold a valid Washington sales tax permit, file sales tax returns by the due date, and pay Washington’s B&O tax.  You can read more about what Amazon collecting Washington sales tax means for Amazon FBA sellers here.
