Do You Need to Get a Sales Tax Permit in Washington? | TaxValet

What is Sales Tax Nexus Anyway?

Your business owes sales tax in any state where it has “sales tax nexus”. In short, if you have sales tax nexus you need to get a sales tax permit in order to collect and remit sales tax. If you don’t have sales tax nexus, you generally don’t need to get a permit. 

Sales tax nexus is a legal term that means you have crossed a threshold and now have a sales tax collection responsibility in the state. Nexus can be created by having a physical presence, economic presence, or by other factors.  Nexus rules vary by state and retailers have specific nexus rules based on where they have people, property or inventory.  

What Should You Do Once You Determine You Have Sales Tax Nexus?

Once you determine that you have sales tax nexus in Washington, your next step is to register for a sales tax permit in the state.  Check out our blog post on getting a sales tax permit in Washington or more information about that process.  

If you are not interested in doing the work of getting the permit yourself, TaxValet can handle the permit registration for you with our Sales Tax Permit Registration Service.

Do You Need a Sales Tax Permit in Washington If You Only Sell on Marketplaces?

If you are an out-of-state online retailer who ONLY sells on approved marketplaces (such as Amazon, eBay, etc), Washington sales tax will be remitted by the marketplace on your behalf.  However, you are still required to get a sales tax permit in the state. Washington has a Business and Occupation tax (B&O) in addition to sales tax. B&O tax is paid by the business, not the customers, based on the total sales in the state.  The current retail B&O rate as of the publishing of this blog is 0.471% or just under one-half percent. There is a credit against B&O tax for small business sellers of up to $850.00. 

For more information about this please see WA DOR Marketplace Sellers.
