For the 2016 deadline, the Internal Revenue Service has given taxpayers until April 18 to pay their taxes, but it is not because the due date falls on a weekend - April 15 is a Friday.
The tax deadline is typically April 15, but this year it was pushed back to Monday, April 18.
There's a legitimate reason for the switch that's pretty interesting, if not a little confusing.
While slavery was not formally abolished in the United States until December 6, 1865, when the 13th Amendment was ratified, it occurred in the District of Columbia much earlier. Emancipation Day marks the day that the Compensated Emancipation Act was signed by President Abraham Lincoln and is observed on April 16.
In an ordinary year, April 15 is tax day.
That's because Emancipation Day is April 16 which falls on a Saturday, so it's now being celebrated on the April 15.
Emancipation Day is a legal holiday in DC, and public employees are given the day off work.
ME and MA residents get an additional deadline extension because of another relatively unknown holiday - Patriots' Day.
