You must use Form FR-127 to request an extension of time to file a DC individual income tax return. A filing extension is not an extension of the due date for paying any tax you may owe.

Include your payment with the FR-127 voucher and file it by April 15, 2015

  • Electronic Filing:
    Washington DC accepts resident returns electronically. The District of Columbia no longer requires that paper documents be mailed to the Electronic Filing Unit. However, it is the responsibility of the ERO/Preparer to securely retain the following documents for a period of three years: Form D-40 E, State copies of Forms W-2, W-2G, and 1099-R, physicians statement for blindness if claimed for first time. In the event that there is a problem with a return, the D.C. OTR may request copies of these documents during the preparer retention period. After the three-year period, all paper documentation may be destroyed. If, for some reason, the ERO/Preparer ceases to do business, all D.C. documents retained during the three-year period should be sent to the Electronic Filing Unit.
