Thanks to a holiday in Washington DC, Americans have until Tuesday to file their income tax returns.

The nation’s capital celebrates Emancipation Day on Monday, marking the date that President Abraham Lincoln freed slaves there in 1862, CNBC reported Friday.

Since April 15 lands on a Sunday this year and the following day is a holiday “they gave the whole country an extra day” to get their tax returns in this year, said Betty Skillen, owner of McPherren’s Tax Services in Crescent City.

“They did that last year too,” Skillen said. “If you look at the calendar, before that (taxes) were always due in the middle of the week. Last year taxes were due on Saturday and Monday was still a holiday.”

Last year taxes were due April 18. According to CNBC, tax day will return to April 15 next year.
