Maine state amended tax return status
Home → About the Maine Tax Portal
Beginning Friday, October 11, 2024 at 5pm, Maine Revenue Services’ computer systems, including the Maine Tax Portal, will be offline for system upgrades. Maine Revenue Services expects to resume normal operation on Tuesday, October 15, 2024.
During this time, taxpayers and tax professionals will not be able to use the Maine Tax Portal, and Maine Revenue Services will temporarily be unable to respond to taxpayer emails and phone calls.
Please note that state offices are closed on Monday, October 14, 2024, in observance of Indigenous Peoples’ Day.
Thank you for your patience while we improve our systems to better serve you.
