Maine Tax Portal Information


In order to improve and increase the capabilities for taxpayers and practitioners, Maine Revenue Services is excited to announce the Maine Tax Portal. The Maine Tax Portal will provide improved functionality and access for Maine people – and integrate all taxes administered by Maine Revenue Services into a new, single online system.

Once implemented this fall and over the next several years, the Maine Tax Portal will enable online filing for all tax types administered by Maine Revenue Services. Additionally, the Maine Tax Portal will allow taxpayers and practitioners to make online payments, view bills and notices, and perform account maintenance activities, such as, adding or removing addresses and closing an account. Depending on access level, authorized representatives may view submissions, letters, messages, and submit payments and returns on a taxpayer’s behalf.

Visit this website often for the most up to date information.  Any questions about the Maine Tax Portal can be submitted via email to with “Portal” in the subject line.
