Tax day is fast approaching, but this year your taxes aren’t going to be due on April 15.

That’s because Friday, April 15, which is usually tax day, is a holiday in Washington, D.C. For that reason, tax day this year is Monday, April 18.

The Emancipation Day holiday, marking the anniversary of an 1862 federal law freeing slaves in the District of Columbia, will give taxpayers who are procrastinators an extra weekend to get their taxes done.
