When are extensions due for filing income tax returns?

Extensions for filing your income tax return are due by the date that your return is due. Returns reporting 2009 income are due by April 15, 2010 in your tax year ended on December 31. To request an extension, you need to file Form 4868, Application for Automatic Extension of Time to File U.S. Income Tax Return. But an extension of time doesn't grant an extension of time to pay your tax liability. If you owe taxes, they're considered due this year by April 15.
