Individual Income Tax Service Center

Welcome to the Office of Tax and Revenue. This center is a gateway for the services and information individual income taxpayers will need to comply with the District's tax laws.

The District of Columbia offers several electronic services that make tax filing and payment fast and secure. Filing directly with the District provides a faster turnaround time for your refund, and, in many cases, electronic filing is provided free of charge. (Electronic filing does not increase the probability of being audited.)

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.
