On many April 14th's we've burnt the midnight oil preparing our tax returns, and this year is no exception. For the 2011 tax return we're still awaiting a Form K-1 from a pass-through entity and will file Federal Form 4868 that will extend the deadline to October 15th.
Filing an extension postpones the need for doing some of the detailed work, but the lion's share still has to be done to determine whether and how much to pay with extension Form 4868. We also need to take a quick look at 2012 because estimated taxes are due the same day.
Thanks to April 15th falling on a Sunday, and Emancipation Day (April 16th) being a public holiday in the District of Columbia, tax-filers have a couple of days grace to work out the numbers. Too bad for residents of DC, though: now that everyone else in America has discovered that DC's special status allows everyone to file and pay one day later every six years, DC will never be granted Statehood. But don't feel bad for them: booming job and housing markets, as well as very low unemployment, ease the pain.
