# How to register for a sales tax permit in the District of Columbia

| 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.

### Provide the Article of Orgniazation

DC sales tax registration requires your formation document. Depending on your business type, please provide:

*   Articles of Incorporation - Business is registered as a "Corporation"
*   Articles of Organization - Business is registered as a "Limited Liability Company"
*   Certificate of Trade Name Registration - Business is registering with a DBA/Trade Name

After Sidr Tax applies for a sales tax permit on your behalf, you will receive your sales tax permit and filing frequency in the mail. It can take 1-2 weeks for you to receive it.

You can then create an account on [myTax DC](https://mytax.dc.gov/_/).
