How do I request an extension of time to file my individual income tax return?

If you require more time to file your return, submit an Extension of Time to File request, Form FR-127, on or before April 15. Any tax due must be paid in full with the request. Penalty and interest will be assessed on any tax outstanding from the time that the return is due until the tax is paid, even though an extension to file is granted. (There is no extension of time to pay.) Note: A copy of the federal application for an Extension of Time to File is not acceptable for requesting an extension of time for filing a DC return.

A granted Extension of Time to File request is valid until August 15. Taxpayers may be granted a second extension that is valid until October 15.


Will I be penalized if I am due a refund, but my return is filed late?

No, you have three (3) years from the due date of the return to file for a refund.
