Will the Maine Tax Portal change how I file returns, make payments, or respond to notices and bills?
The Maine Tax Portal is meant to improve access and increase capabilities for taxpayers and practitioners to electronically interact with Maine Revenue Services. While we currently offer online filing for certain tax types, the Maine Tax Portal will expand online capability to all tax types administered by Maine Revenue Services. In addition, the Maine Tax Portal will allow taxpayers and authorized third parties to register for taxes, file tax returns, make payments, view bills and notices, and perform online account maintenance activities, such as, adding or removing addresses and closing an account. Expanded online capabilities for Rollout 1 taxes and fees are shown below. For Rollout 2 functions, see What MTP functions are included for Rollout 2 Taxes and Programs?
The rollout schedule for all other tax types is available at www.Maine.gov/revenue/portal. Account setup instructions and other tutorials will be published over the coming months at www.Maine.gov/revenue/portal.

Rollout 2 Taxes
Property Tax Programs
What logged in functions are included for Rollout 3 Taxes and Programs?
MTP will provide extensive capabilities to taxpayers and program participants on a logged-in basis. Logged-in capabilities require a taxpayer to obtain a MTP username and to logon with that username and a password established when the username is obtained. When logged-in, key functions are easier to perform because account numbers, address information, bank information and other data are stored and need not be entered. It is important to note that capabilities may differ by tax type or program. R3 MTP logged-in capabilities are listed below:
(1) Cigarette Tax Refunds may also be requested
(2) Includes adding/removing addresses, closing accounts, updating contact Information, view filing/payment history, and outstanding balances
(1) May upload MVR in specified spreadsheet format
(2) Includes adding/removing addresses, closing accounts, updating contact Information, view filing/payment history, and outstanding balances
What non-logged in functions are included for Rollout 3 Taxes and Programs?
MTP will provide limited capabilities to taxpayers and program participants on a non-logged-in basis. Non-logged-in functions can be performed without the need to obtain a username or password. It is important to note that functions may differ by tax or program. Filing an individual tax return is a non-logged-in function.
Notes:
(1) Cigarette Tax Refunds may also be requested
Why are new Taxpayer Account Numbers being assigned?
All tax types that are included in the Maine Tax Portal will be assigned a new account ID to increase efficiencies in processing returns and payments. This will allow taxpayers to better manage their accounts and provide an added layer of security for taxpayer information. New account numbers will be assigned as each tax type or fee is implemented in the Maine Tax Portal.
To ease the transition, taxpayers may continue to use existing account numbers when filing returns or making payments and in any correspondence to Maine Revenue Services.
If a taxpayer currently holds a certificate from Maine Revenue Services, an updated certificate with the new account ID will be issued.
What web browsers should be used to access the Maine Tax Portal?
The following web browsers are recommended for accessing the Maine Tax Portal:
- Microsoft Edge
- Safari
- Google Chrome
- Mozilla Firefox
- Opera
The current version of each of the above browsers is supported along with one prior version. Microsoft 365 has discontinued support for Internet Explorer 11 and is not recommended for accessing the MTP. Microsoft Edge’s IE mode provides built-in support for legacy websites and applications that still require Internet Explorer.
Will taxpayers be able to set up payment plans in the Maine Tax Portal?
Starting on December 1, 2022, registered MTP users will be able to set up payment plans via the MTP for all Rollout 1 and Rollout 2 taxes and programs. See for a list of Rollout 1 and Rollout 2 taxes and programs. All payment plans set up via the MTP will be subject to review and approval by MRS.
What should Sales, Use, and Service Provider Tax taxpayers know about the second rollout of the Maine Tax Portal on December 1, 2022?
- Changes coming for Sales, Use, and Service Provider Tax taxpayers include:
- New Account Numbers - Sales, Use, and Service Provider Tax taxpayers will receive new eight-digit tax account numbers starting in December 2022.
- Updated Certificates - Sales Tax taxpayers will be receiving updated Retailer and Resale Certificates showing the new account numbers. Exempt taxpayers will also be receiving updated Exemption Certificates. These updated certificates will be issued and sent starting in November 2022. Taxpayers will need to provide updated copies of the certificates to their vendors.
- Reprogramming Registers - Retailers who currently have their registers programmed for the existing seven-digit account numbers may need to reprogram those registers for the new eight-digit account numbers.
- New File Format - “Consolidated” filers (those filing for multiple Sales or Service Provider Tax locations) will use a different file format to submit their return. MRS will provide the revised file format in future correspondence and on MRS’s website in coming months.
- i-File - Beginning on December 1, 2022, i-file (the current MRS online filing solution) will be limited to filing an original return. All return filing (original and amended), payment, account and address maintenance, and other online services will be available on the MTP at that time. The limited i-File functionality will continue to be available until early 2023.
What Estate Tax Functions are Available on Maine Tax Portal?
Estate Tax forms are now accepted on the Maine Tax Portal (MTP). Personal Representatives of the estate can file either Form 706ME or the Form 700-SOV (Statement of Value). For information on which of these forms should be filed, click here. If you are a third-party Authorized Representative, filing on behalf of the Personal Representative, you can file the Form 700-SOV (Statement of Value) and Form 706ME as a “non-logged-in activity” on the MTP. To access the MTP, click here.
Where are my Estimated Tax Payments?
Estimated tax payments processed after October 21, 2021 for Rollout 1 taxes are visible in the MTP. Estimated tax payments made prior to that date have been credited to taxpayer accounts in MRS’s legacy tax system and will be applied to any new tax debt as appropriate. See What is the Maine Tax Portal? for a list of Rollout 1 taxes.
Do taxpayers and authorized third parties have to use Multi-Factor Authentication to access MTP accounts?
Yes, MRS requires multi-factor authentication to access and use MTP accounts to secure accounts and taxpayer data. MTP users may receive texts or emails to obtain the required confirmation code (which then must be entered at the prompt on the MTP to gain access) or may use an authentication app such as Google or Microsoft Authenticator.

Where can I learn more?
Sign up for Maine Revenue Services’ Tax Alerts and watch your inbox for more information or visit www.Maine.gov/revenue/portal. Any questions about the Maine Tax Portal can be submitted via email to taxpayerassist@maine.gov with “Portal” in the subject line.
How do I know if the returns I have filed on the Maine Tax Portal have been received by Maine Revenue Services?
Any tax return filed through the Maine Tax Portal (MTP) will be acknowledged by a Submission Confirmation message on your screen that lets you know your return has been received and is being processed. You can also view your pending MTP submissions on the Submissions Tab in the system. Once your return has been filed on the MTP, users should not file a duplicate return through our older systems, MEETRS or I-File (these systems are being deactivated on May 31, 2023), or file a duplicate return on paper.
I registered for a tax using the Maine Tax Portal (MTP); how will I know if and when that registration is established?
Here are the key things to know:
For all new tax accounts except Cannabis Excise Tax:
- You will know that your tax registration has been accepted when you receive a confirmation number from the MTP, upon completion of the new tax account registration
- Once you have set up a MTP username, you will see your new tax account and the account number for that tax account in the system
- You may immediately file returns, make payments, view balances, and perform other MTP functions for the particular tax right away
For new Cannabis Excise Tax accounts, the process for registration is the same as explained above; also, the new account number is immediately viewable in the system for those who have established a MTP username. However, Maine Revenue Services (MRS) performs an additional review to verify cannabis eligibility. If eligibility is confirmed, no further action is required. If taxpayer eligibility is denied, the Cannabis Excise Tax account will be removed and MRS will contact the applicant, explaining the reason(s) for the denial.

How do I sign up for the Maine Tax Portal for Rollout 1 Taxes and Programs?
Taxpayers and authorized third parties for Rollout 1 taxes and fees may register now to use the Maine Tax Portal at https://revenue.maine.gov/_ /.
Once you have navigated to the MTP click on "Create a Username" and follow the instructions to complete your registration. You will be required to provide ID (e.g. SSN, EIN, or TIN), name, address, logon credentials, contact phone number, and email address.

How do I sign up for the Maine Tax Portal for Rollout 2 Taxes and Programs?
Here is what you need to do:
a. Watch the mail. Invitations to register for the Maine Tax Portal will be mailed to you starting in November 2022.
b. In the meantime, download your account history. For your records, download your filing and payment history from I-File, MEETRS, and EZ-Pay. Once I-File, MEETRS, and EZ-Pay systems are deactivated on May 31, 2023, your historical account information will no longer be available on those platforms.
c. Sign up for an upcoming Maine Tax Portal training webinar. MRS will host free, live training webinars beginning in August 2022 – see schedule online at maine.gov/revenue/portal .
d. After December 1, 2022, remember to set up your Maine Tax Portal account. You will need your Social Security Number or Employer Identification Number, and either a Letter ID (found in the top right corner of recent Maine Revenue Services correspondence for a R1 or R2 tax type) OR the dollar amount of a tax return or refund from one of the past three filings. The letter ID is formatted as L#####.
e. Coordinate with your tax professionals. If you use a third-party tax professional, such as a tax accountant, to prepare your business taxes both you and the tax professional will need to create Maine Tax Portal accounts. Third parties must request access to their clients’ Maine Tax Portal accounts, and clients must authorize access. Step-by-step instructions and resources are available on the MRS website at maine.gov/revenue/portal .
f. Confirm when you should begin using the Maine Tax Portal, based on your tax type and filing frequency - see schedules below.
