AUGUSTA — Maine Revenue Services (MRS) is urging all taxpayers who are eligible to use the Maine Tax Portal, Maine’s new online state tax system. MRS has opened the Maine Tax Portal to more than 140,000 business taxpayers for filing and payment of various business taxes, including, but not limited to Sales, Use, Service Provider, and Income Tax Withholding.

Business owners and tax professionals should visit to start using the Maine Tax Portal or access online training, FAQs, and other important information by visiting

The Maine Tax Portal is replacing Maine Revenue Services’ current online services, including I-File, MEETRS, and E-Z Pay. On May 31, 2023, I-File, MEETRS, and EZ-Pay will be deactivated, for most business taxes and programs, after which time the Maine Tax Portal will be the sole online filing and payment option for those taxes and programs. Taxpayers and tax professionals are strongly encouraged to print records from the I-FILE system before May 31.

“It’s very important that all taxpayers who can use the Maine Tax Portal create new usernames and passwords on the new online system as soon as possible, and before the older systems are deactivated. Don’t wait until the last minute,” said Kirsten Figueroa, Commissioner of the Maine Department of Administrative and Financial Services (DAFS). “The Maine Tax Portal significantly expands online functionality making it faster, easier, and more convenient for taxpayers to file, pay, and manage their Maine taxes.”

The opening of the Maine Tax Portal for businesses is part of a multi-year rollout that will be complete by the end of 2024. The Maine Tax Portal will be rolled out for all individual income tax filing, and 10 other tax programs in October 2023. In the final phase of the rollout, in October of 2024, the Maine Tax Portal will open to 20 additional tax types and programs. The complete rollout schedule is available at
