ACTION NEEDED: Set up your Maine tax portal account


Set up your Maine tax portal account by December 31, 2022. Setting up an account and taking appropriate action now will help your business remain in compliance. 


We encourage you to perform the following steps before December 31, 2022:

  1. Keep track on your your email regarding the invitation to register for Maine tax portal.
    You should receive this email within the month of November 2022. The email will include the following information:

    • Letter ID required to create your new Maine tax portal account

    • New 8-digit account number
      Note: if you do not receive an invitation from the state, you’ll still be required to create a new Maine tax portal account in December 2022. For alternate registration options, see step 3. 

  2. After December 01, 2022, create your Maine tax portal account.
    If you’ve received an invitation letter from the state, reference the Letter ID and 8-digit account number listed there. If you have not received an invitation letter by December 1, 2022, create an account using your social security number or your employer identification number and the Dollar amount of a tax return or refund from one of the past three filings. For information on downloading past returns, see Download past returns and confirmations

  3. After you’ve created your new Maine tax portal account, update your scheduled returns in AvaTax with the following information: 

    • Your new 8-digit account ID

    • Your new username and password for the Maine tax portal website

  4. Update your Maine Tax Portal account with a two-factor authentication email to allow you and Avalara to get the login security prompts.
    To update your two-factor authentication email, do the following:

    1.    Login to your business account on the Maine tax portal website. 

    2. In the top-right corner of the main screen, select Manage My Profile.

    3. Under the Profile tab, go to the Security box, and select Change Two-Step Settings.

    4. Update your business's two-step authentication email by using the email address associated with your account. This can be found within your AvaTax login. For detailed instructions to set up two-factor authentication, see  Set up two-factor authentication in Avalara Returns. 

For more information, see Learn more about two-factor authentication.

Additional information

On May 31, 2023, I-File, MEETRS, and EZ-Pay will be deactivated. At that time, the Maine tax portal will be the only way to electronically file and pay taxes.

The state has suggested that you download your account history. For your records, download your filing and payment history from I-File, MEETRS, and EZ-Pay. Once these systems are deactivated by the state, your company’s historical account information will no longer be accessible. 

Information to track after December 1, 2022

Avalara will create a third-party tax professional account to enable easy filing of your business tax returns. Therefore, you must have a Maine tax portal account to grant a third-party access to your accounts. After December 1, 2022, Avalara will request access to your Maine tax portal account, and therefore, your access authorization will be required.

For step-by-step instructions and resources, refer to Maine Revenue Services website

Once Avalara has requested access, you may approve or manage our access while logged in by doing the following:

  1. Select the Manage my Profile link.

  2. In the Profile section, select the Change Email link.

  3. In the Access section, select the Request Third Party Requests link.

  4. Grant or deny access to any pending requests.
    Ensure that you have verified who is requesting access to your accounts before granting any access.

In December 2022, Avalara will send additional instructions regarding third-party accounts and access.
