How to register for a sales tax permit in South Carolina

Login to your South Carolina MyDorway account

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.

South Carolina MyDorway is the South Carolina system for sales tax filing. After Sidr Tax applies for a sales tax permit on your behalf, you will find your username in our app. Access it by going to the registration page and clicking on the details button. You will also receive an email from South Carolina DOR with your temporary password. Verify your login with your username and password.
