FR-127 Extension of Time to File a DC Income Tax Return
An extension of time to file of six months may be granted if a valid extension of time to file is requested. In order to be valid, an FR-127 Extension of Time to File form is due by April 15, 2021. If the due date falls on a Saturday, Sunday, or legal holiday, the request for extension of time is timely if filed on the next business day. The submission of the extension of time to file is subject to the following considerations:
1. If you expect to have a balance due when you file your D-40, you must pay with your timely filed extension. Penalty and interest charges are imposed on any tax found owing and not paid on time with the extension request.
2. If you do not expect to have a balance due when you file your D-40, you would not be required to file a Form FR-127, if you have reasonably estimated your D-40 tax liability and paid the estimated amount of DC income taxes through withholding or estimated tax payment; and
3. If you do not expect to have a balance due and wish to request an extension for your DC income tax return, you should submit a Form FR-127.
Additional extensions In addition to the 6-month extension, you may receive an additional 6-month extension if you are living or traveling outside the U.S. You must file for the first 6-month extension by the April 15, 2021 deadline before applying for the additional extension of time to file.
