1. Am I eligible to electronically file with Maine?
Most residents, part-year residents, and nonresidents may electronically file their individual income tax returns via the Maine Tax Portal (MTP) at revenue.maine.gov.
Taxpayers may also file electronically via Modernized e-File (MeF) by using a participating tax professional, purchasing approved tax preparation software, or visiting an approved commercial software vendor site. When selecting tax preparation software, please make sure the software has been approved by Maine Revenue Services (MRS) and provides all the Maine tax forms you need to file your return. Contact the tax preparation software company if you find that the software you have purchased does not fit your Maine tax-filing needs. For more information on MeF, visit irs.gov/filing/individuals/how-to-file.

2. How do I know if my return has been accepted?
The Maine Tax Portal (MTP) issues a confirmation code to indicate that a return has been accepted. To view returns filed on the MTP, visit the MTP at revenue.maine.gov and click 'Find a Submission'.
Modernized e-File (MeF) issues an acknowledgement on the filing status of your return. If you feel that an MeF return has successfully been transmitted and you have not received an acknowledgement within 48 hours, contact the software company that transmitted the return to Maine. Maine processes electronic returns as soon as they are received, and the acknowledgements are immediately posted for the transmitter to pick up. It is the responsibility of the software company transmitting the returns to Maine to pass along acknowledgements to taxpayers in a timely and efficient manner.

3. I have filed my Maine return using Modernized e-File (MeF) and received one or more reject codes. How do I find out what the codes mean so I can fix the problem and retransmit the return?
The software that you are using should give you some indication of what the problem is. If not, please contact the software company for assistance.

5. I need to amend my Maine income tax return. Can I do this electronically?
Yes, both the Maine Tax Portal and Modernized e-File support filing original and amended returns for the current year and the two immediately preceding tax years.

6. What is Maine's Modernized e-File (MeF) application process for out-of-state Electronic Return Originators (ERO's)?
Maine Revenue Services (MRS) has access to Internal Revenue Service (IRS) approved electronic filing identification numbers through the IRS database, so it is not necessary to fax or email federal acceptance letters to us. Once you are accepted by the IRS to e-File a federal income tax return, then MRS automatically accepts Maine individual income tax returns submitted through MeF.
