Individual Income Tax Service Center

OTR Tax Service Center Logo

This center is a gateway for the services and information that personal income taxpayers will need to comply with the District's tax laws.

DC Online Filing is a secure site that provides full calculation of District tax and credits and currently allows District residents to file the D-40 and D-40EZ individual forms for free. This site is available 24 hours a day, seven days a week. The Federal/State E-File program allows taxpayers to file their federal and DC returns electronically at the same time. (Electronic filing does not increase the probability of being audited).

Feel free to call or visit our Customer Service Center for additional assistance.
