Microsoft Outlook offers a way to automatically insert holidays and other events in the calendar. If you’ve done this, your version may say (as ours does) that April 15, 2011 is “Tax Day” in the U.S. Not true! Emancipation Day, a holiday in the District of Columbia, falls on April 15 this year, and that means IRS deadlines that would otherwise fall on that date are delayed until Monday, April 18.
The delayed deadline applies to Form 1040, filing for an extension, first quarter estimates, IRA contributions for 2010, and any other federal tax item that would normally have an April 15 deadline. If filing a state return, check to see whether your state recognizes this extension.
