Your deadline for filing a Maine income tax return and paying tax you owe is pushed back 180 days after your last day in a combat zone, or after the last day of continuous hospitalization for an injury from combat zone service. On top of the 180 days, you also get back the number of days you had left to file or pay when you entered the combat zone.
There is nothing to file in advance. File and pay within the extended window, and contact Maine Revenue Services if you receive a notice that does not reflect the extension.
Your orders or Leave and Earnings Statements showing the combat zone dates, or hospital records showing the period of continuous hospitalization.
