How to register for a sales tax permit in Washington

If your state is registered through Streamlined Sales Tax, read this guide.
Sidr Tax creates the sales tax account for you. However, this state requires that you have your own login and we access your account as a third-party.

Create your Washington My DOR Login

After Sidr Tax finishes the registration for you, you will receive the sales tax ID in the mail. You will then need to create a login at Washington My DOR to access your sales tax account.

Once you have an account with Washington My DOR, you will be able to request access to two different accounts: a business license account and an excise tax account.
