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).
