FAQs
What is exempt from sales tax in Washington?
In Washington, exemptions include wholesale purchases and goods bought for resale with a valid Reseller Permit. Manufacturing equipment used directly in production is also exempt. Note that most digital products are taxable in Washington. That includes downloaded software, streaming media, digital books, and NFTs. They're exempt only when bought for resale. Digital goods are also exempt when a business buys them only for business use and gives an exemption certificate.
Do non-residents pay sales tax in Washington state?
Yes, non-residents generally pay sales tax on purchases made in Washington. But residents of states without a sales tax (such as Oregon, Montana, or Alaska) may ask for a refund of Washington sales tax paid on qualifying purchases. They file a refund request with the Washington Department of Revenue. This is a refund process, not an exemption at the register. The seller collects tax at the time of sale, and the buyer must file for a refund later.
Who qualifies depends on the buyer's home state and the type of goods bought. This process can help cross-border eCommerce and SaaS businesses that handle sales in many states.
