How to register for a sales tax permit in Missouri
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.
After Sidr Tax applies for a sales tax permit on your behalf, you will receive your Missouri sales tax ID, and filing frequency in the mail.
Once you receive your sales tax ID, access code, and filing frequency in the mail, you can create a login at Missouri MyTax to access your sales tax account.
Click Create an Account, and then Administrator for My Individual and Business accounts on the right hand side.
Provide your login information.
You should see the registration confirmation page. The means that your login is setup, however you don't have access to your business yet. Please continue.
