How to register for a sales tax permit in Maine

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 a Maine Tax Portal (MTP) Login

After Sidr Tax applies for a sales tax permit on your behalf, you will receive your Maine sales tax ID, and filing frequency in the mail.
Once you receive your sales tax ID, and filing frequency in the mail, you can create a login at Maine Tax Portal (MTP) to access your sales tax account.

On the next screen, you need to provide the Letter ID and Letter Date. You can find both information on the top right corner of the registration letter you received.
