Where should I mail my tax return and/or payment?
The mailing address for the D-40 and D-40EZ individual income tax returns is Office of Tax and Revenue, PO Box 96169, Washington, DC 20090-6169. If mailing a refund or no payment return, mail to the Office of Tax and Revenue, PO Box 96145, Washington, DC 20090-6145.  Visit Mailing Addresses for DC Tax Returns [PDF] to learn where to mail other tax forms.

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 if an extension to file is granted. (There is no extension of time to pay.) A copy of the federal application for an extension of time to file is acceptable for requesting an extension of time for filing a DC return.

By filing a timely Form FR-127, plus any payment due with the extension, you have a 6-month extension of time to file until October 15. In addition to this initial extension, you may receive, upon request, an additional 6-month extension if you are living or traveling outside the United States. 

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.
