How to register for a sales tax permit in Arizona

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


Create Your Sales Tax Account at AZTaxes


If you do not have an AZTaxes login, you will need to create a login first. If you already have one, please skip to the next section.

The reason that you need to create a login first is that this login will be treated as the primary administrator of your Arizona tax license. If Sidr Tax register for you using the Sidr login, your business won't be the administrator, but a delegate instead. This is not ideal. Please follow the steps below to create your login.


  • Go to the AZTaxes website.
  • Click Enroll to File and Pay Online


Click "Enroll to File and Pay Online"


  • Fill out your login information.


Fill out login information


  • You will receive a temporary password in email. The email subject is: AZTaxes.gov Registration Confirmation Part II. You can then login at AZTaxes.
  • Username: the email that you used in the login creation form just now.
  • Password: the temporary password you received in the email.


Find your temporary password in your email


  • Using the temporary password, you can then go through the setup process to create your new password and PIN.
  • Please share your username, password, and PIN with us, and we will continue the registration for you. You can share with us through chat in our app, or email support@sidr.io.
  • After we setup the account for you, you can access your account credentials by clicking on Arizona Details button on the registration page.


Link expired?The temporary password in the email expires in 24 hours, but you can click the link in the email to reset a new password. If you no longer have your password, please visit AZTaxes and reset your password. You can reset password by clicking "Login to AZTaxes", login with your email and click "Forget your Password?". Once you finish setting up your AZTaxes login, please share both your password and PIN with us.


Share your existing AZTaxes Login


If you already have an AZTaxes account, please share with us by adding it to the Existing State Accounts field.

You can see the field when you add a new Nexus state, or click on the Details button after you created the Nexus state.

Please make sure to provide AZTaxes username, password, and PIN. Please note that your username is typically your email.


Please provide your AZTaxes username, password and PIN.


If you forgot your PIN, you can reset it by clicking on the Reset PIN button on the left. Sidr Tax will not be able to finish your registration with the PIN.
