When Should You File?(p6)

File Form 1040EZ by April 18, 2011. (The due date is April 18, instead of April 15, because of the Emancipation Day holiday in the District of Columbia—even if you do not live in the District of Columbia.) If you file after this date, you may have to pay interest and penalties. See What if You Cannot File on Time? on page 21 for information on how to get more time to file. There is also information about interest and penalties.

If you were serving in, or in support of, the U.S. Armed Forces in a designated combat zone or a contingency operation, you can file later. See Pub. 3 for details.
