Do I Need to File Taxes in D.C.? What is My Residency Status?
There are four groups of people who need to file some sort of tax form in Washington, D.C. Washington, D.C. residents, part-year Washington, D.C. residents, people who live in Washington, D.C. but work in another state, people who live in another state and work in Washington, D.C.
Washington, D.C. Residents
If your permanent domicile was in Washington, D.C. for the entire year or for more than 183 days, you are a D.C. resident. You are also a D.C. resident if you owned a home in Washington, D.C. and are in the armed forces or are a spouse of someone in the armed forces or a nonresident elected official who is otherwise exempt from D.C. residency. Washington, D.C. residents who filed a federal tax return must file a return with Washington, D.C. using Form D-40.
If you only resided in Washington, D.C. for part of the year or fewer than 183 days you are a part-year resident. People who were physically in Washington, D.C., but whose residence was in another state are also considered Washington, D.C. part-year residents. You are only permitted to have one permanent residence and changing that residence requires you to give up your other residence and establish your residence in the new state.
Part-year D.C. residents are required to file a Form D-40 Washington, D.C. return just like full-year residents. There are however several differences. When filling out the Filing Status section, you need to declare that you are a part-year resident. For more information see page 12 of Form D-40. You also need to calculate how much income you earned while you were a D.C. resident and how much when you weren’t. You will need to repeat that process for deductions, exemptions, and deductible expenses. Divide the number of days you lived in D.C. by 30 to find out how many months you lived in D.C. so you know how to prorate those calculations. Any remainder greater than 15 is considered a full month for filing purposes. Enter these calculations on your Form D-40 return.
Make sure that when you are entering this information, you allocate income and deductions to Washington, D.C. for the time you were a D.C. resident. Don’t forget to prorate your personal exemptions and deductions, both standardized and itemized, as well as any credits.

If you have determined that you are a Washington, D.C. resident and you worked in Maryland or Virginia, you are required to file a D.C. return. Out of state employers may not have withheld taxes for D.C. so you will need to file Form D-40 with Washington, D.C. The state you worked in may also require you to file something with before it can release withheld taxes.
Work in Washington, D.C., Live Out of State
If you lived outside of D.C all year or for fewer than 183 days, you are not a D.C resident. Your employer may have withheld D.C. taxes from your income and if you want a refund, you will need to file a Washington, D.C. return. Use Form D-40B to file a nonresident return with Washington, D.C. You must attach any documentation of D.C. withholdings to page 1 of Form D-40B when you file. You may not request joint refunds.
