You get an extra three days to file your income tax this year. in a news release, the IRS says taxpayers can file returns by April 18 instead of the normal April 15. It can be considered an act of generosity spurred by Emancipation Day, a holiday observed in the District of Columbia, falling on the 15th this year. "By law, District of Columbia holidays impact tax deadlines in the same way that federal holidays do," the IRS said. The extra time will also apply to taxpayers requesting an extension, who will have until October 17 to file. The IRS said it expects to receive more than 140 million individual tax returns in 2011.
