District of Columbia Personal Tax Extension Guide

Form FR-127  ·  Individual Income Tax  ·  Personal Filing Guide

Unlike most states, the District of Columbia does not accept the federal IRS extension. DC residents who need more time to file their personal income tax return must file Form FR-127 (Extension of Time to File a DC Income Tax Return) directly with the DC Office of Tax and Revenue. Filing IRS Form 4868 alone will not extend your DC filing deadline.

DC's extension is for filing only. Full payment of any tax liability (less credits) must be submitted with your Form FR-127 by April 15, 2026. Submitting the extension form without full payment may result in penalties and interest on the unpaid balance from the original due date. If you are uncertain of your exact liability, estimate it and pay as much as possible to minimize charges.

DC taxpayers can make extension payments online at mytax.dc.gov:

• Credit/Debit Card: Visa, MasterCard, Discover, and American Express are accepted. A fee is charged by the District's credit card service provider.
• ACH Debit: Available to taxpayers registered at MyTax.DC.gov. No fee. Bank account information is stored securely within your online account.

File Form FR-127 by April 15, 2026, with full payment of your estimated DC tax liability. The form can be filed online through MyTax.DC.gov or mailed with payment to:
Office of Tax and Revenue
P.O. Box 96018
Washington, DC 20090-6018

DC imposes a failure-to-file penalty of 5% of unpaid tax per month, up to a maximum of 25%. Failure to pay carries an identical 5% monthly penalty, also capped at 25%. Both penalties can run simultaneously if no extension is filed and no payment is made.

• Do not rely on your federal Form 4868 to extend your DC filing deadline—Form FR-127 is required separately.
• File Form FR-127 with full payment by April 15, 2026, to secure your extension to October 15.
• Register for MyTax.DC.gov to use ACH debit—no fee and instant payment confirmation.
• Save all confirmation numbers and copies of Form FR-127 for your records.

DC's extension process is straightforward but requires action—the federal extension does not apply here. File Form FR-127 and pay your estimated DC tax liability by April 15, 2026, to receive an extension to October 15. Use MyTax.DC.gov for the fastest and most secure payment experience.
