The last day to pay your 2016 federal income taxes is April 18, 2017, a date commonly known as Tax Day. This payment deadline applies whether you file a tax extension or not. Here’s what you need to know about the tax deadline, as well as what it will cost if you pay late.
Tax Day in the United States generally falls on April 15, unless that date falls on a weekend or holiday. In 2017, thanks to a weekend and a holiday (Emancipation Day — a D.C. holiday), Tax Day is pushed back to April 18.
