When and Where Should You File?(p6)

File Form 1040A by April 17, 2012. (The due date is April 17, instead of April 15, because April 15 is a Sunday and April 16 is the Emancipation Day holiday in the District of Columbia.) If you file after this date, you may have to pay interest and penalties. See Interest and Penalties, later.

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

Filing instructions and addresses are at the end of these instructions.
