Washington State Sales Tax for Shopp


Washington State is a destination-based sales tax state. As a Washington-based business, if you sell taxable items within WA, you charge the tax rate of the destination you’re shipping to, rather than the rate of where you’re shipping from.

When selling digital goods, the billing address is use to calculate tax.

Most e-commerce platforms have relatively rudimentary tax calculation tools and tables. Shopp, while robust, doesn’t have the ability to calculate the actual sales tax in Washington State based on destination address and zip.

When enabled, the customer’s zip and address information is passed up to the WA DOR along with some basic information about the order and it returns the actual tax rate, and amount for the ship-to address.

Sorry, just Washington State.

I’m not sure if I need to use this plugin. I live in Washington, but don’t know if I need to collect sales tax. Can you help?

Unfortunately, we can’t advise you what taxes you’re liable to pay the State of Washington.

We recommend that you contact the Washington Department of Revenue or your accountant.

= My accountant says I should use this plugin; can you help make sure it’s installed correctly, provide customization, or help me with other Shopp questions?

Absolutely. Please contact us and let us know what you need and we’ll be happy to provide an estimate.
