I don't see my tax type listed? When can I use the Maine Tax Portal?

The Maine Tax Portal is being rolled out in phases.  It is currently only available for certain business taxpayers, as well as authorized third parties such as tax preparers. The Maine Tax Portal will be open for individual income tax filing in October 2023, and will eventually be available for all taxpayers in Maine.  To find out who can use the Maine Tax Portal now, see the rollout schedule.
