Tax day extended to April 18- This year only

The bonus days come thanks to Emancipation Day, a little-known Washington, D.C., holiday that celebrates the freeing of slaves in the district.

Emancipation Day falls on Sat., April 16, but it is observed in D.C. on Fri., April 15. That prompted the IRS to extend the tax filing deadline to April 18 this year. Under the tax code, filing deadlines can’t fall on Saturdays, Sundays or holidays.
