Editor's note: This story originally appeared on October 28, 2010, but has been updated to reflect new information.
If you're one of the hundreds of thousands of taxpayers who wait until the last minute to file your taxes, make a note: The IRS recerntly announced that the due date for 2010 individual federal income tax returns will be Monday, April 18, 2011.
Traditionally, Tax Day falls on April 15 unless that day happens to be on a Saturday, Sunday or federal holiday. In 2011, April 15 meets none of those criteria -- it falls on a Friday, and there's no federal holiday that day.
So what's the deal?
