With deadline approaching, here's how to move your business to the Maine Tax Portal

For most Maine businesses, it’s time to move to the Maine Tax Portal, Maine Revenue Services’ new online system for filing, paying, and managing state business taxes. The Maine Tax Portal is replacing I-File, EZ-Pay, and MEETRS.

On May 31, 2023, MRS will deactivate I-File, EZ-Pay and MEETRS, and the Maine Tax Portal will be the only option for filing, managing and paying Maine state business taxes online. 

The Maine Tax Portal is a multi-year modernization effort that, once complete, will make filing, managing and paying all Maine state taxes faster, more convenient and more efficient for all taxpayers.

For now, the Maine Tax Portal is only open for businesses, but will open for individual income taxpayers beginning Oct. 9, 2023.

On the Maine Tax Portal, business owners and tax professionals can file and pay state taxes, establish payment arrangements, update account details, check on refunds, and view notices from MRS 24 hours a day, seven days a week.

Maine Revenue Services understands change can be challenging, and tax time can be stressful. We are confident the Maine Tax Portal will make managing state taxes much easier, whether you’re a business owner, tax professional, or someone responsible for managing your company’s taxes.

If your business has not yet made the move to the Maine Tax Portal, here’s what you need to do:

  • Create a new Maine Tax Portal account. It’s quick and easy. You’ll need your Social Security Number or Employer Identification Number, and the dollar amount of a tax return or refund from one of the past three filings. Go to and follow the Create a Username prompt.
  • Gather your records. Print your filing history from I-File, which will be deactivated on May 31, 2023. Your I-File records won’t be accessible on the Maine Tax Portal. Going forward, any account activity on the Portal will be accessible online anytime.
  •  Coordinate with your tax professionals. If you have third-party tax professionals prepare your business taxes, you will still need to create an account on the Maine Tax Portal. Both you and your tax professionals will need to create your own accounts. Once you have done that, you will need to authorize your tax professional to access to access your account. Step-by-step instructions and resources are available on
  • Reach out for help. MRS has training videos, Frequently Asked Questions, and other resources at The agency’s staff is available to answer questions via email or phone. Send MRS a message at with “MTP” in the subject line or call us at 207-624-9784

Maine Revenue Services is committed to making the transition to the Maine Tax Portal as seamless as possible for all Maine taxpayers. We encourage you to make the move to the new system and contact us with any questions.
