General Instructions
Choose your state from the list below to access detailed instructions for both business and personal tax extensions.
Corporate income tax returns are due by March 15 — or by the 15th day of the 3rd month following the end of the taxable year (for fiscal year filers).
Maine offers a 7-month extension, which moves the filing deadline to October 15 (for calendar year filers).
Maine’s business extension is automatic, so there is no application or written request to submit.
An extension of time to file is not an extension of time to pay. If you owe Maine tax, it must be paid by the original due date to avoid penalty charges. You are required to pay at least 90% of your Maine tax liability in order to receive the automatic extension.
You can make a Maine extension payment with Form 1120EXT-ME, or pay electronically through the EZ Pay Internet Payment System: portal.maine.gov/ezpay
