Why are my 2006 taxes due on April 17, 2007?
As you know, taxes are usually due on April 15. But in 2007, the 15th is on a Sunday, which means the due date moves forward to the following Monday. So why aren’t taxes due on Monday, April 16? Well it turns out that the 16th is a holiday in D.C. (Emancipation Day) and a state holiday in Massachusetts (Patriots Day). Plus, several other states had bumped their return due dates to April 17, so the IRS decided to follow suit and move the deadline to Tuesday, April 17, 2007.
