Is SaaS taxable in Washington?

by TaxJar September 18, 2020


Sales tax can be complex when you sell a SaaS product. For one thing, some states consider SaaS taxable while others don’t. Further, some states dig even deeper, and pass laws that say things like SaaS is taxable if your customer is other businesses (B2B) but it’s not taxable if you are selling business-to-consumer (B2C). 

This post will go over what you need to know about SaaS taxability if you are selling SaaS products to customers in Washington State.

Should your business charge sales tax on SaaS in Washington?

SaaS is generally always taxable in Washington. 

Washington refers to SaaS as “remotely accessed software (RAS)” and says: 

“RAS is prewritten software provided remotely. In other words, the buyer pays the seller for the right to access and use the prewritten software, which resides on the seller’s server or the server of a third party. (An Application Service Provider is an example of a business that may provide RAS.) RAS is classified as a retail sale for B&O tax purposes and is subject to sales or use tax. The purchase of prewritten software is exempt if the purchaser uses the software to provide RAS.”

In other words, prewritten software accessed remotely by the consumer is subject to sales tax in the state of Washington.
