Washington D.C. Filing Due Date: Individual income tax returns are due by April 15.
Extended Deadline with Washington D.C. Tax Extension: The District of Columbia offers a 6-month extension, which moves the filing deadline to October 15.
Washington D.C. Tax Extension Form: You can apply for a DC extension by filing Form FR-127 on or before the original deadline of your tax return (April 15).
Washington D.C. Extension Payment Requirement: An extension of time to file is not an extension of time to pay. If you owe DC income tax, it must be paid by the original due date — or interest and penalties will be charged.
