Taxpayers have an extra day, until Friday, Jan. 10, to file any return or pay tax originally due on Thursday, Jan. 9.
The IRS granted the time for the Jan. 9 National Day of Mourning for Jimmy Carter, the 39th U.S. president. He was the longest-lived president in history, dying December 29 at the age of 100.
The one-day extension also applies to any federal income, payroll or excise tax deposits due on Jan. 9, including those required to be made through the Treasury Department's Electronic Federal Tax Payment System.
