When Do I Need to File a Maine Amended Tax Return?

If you are filing a Maine tax amendment as a result of corrections made by the IRS, you must file it within 90 days of receiving final notification.

If you are expecting a state refund, then you must file your tax amendment within 3 years of the original filing deadline or 3 years after you paid the tax, whichever date is later.

If you are filing a tax amendment because of bad debt or a security that's now worthless, you have up to 7 years from the due date of the tax return in the year when the debt or security became worthless to file a tax amendment indicating the change.
