Washington D.C. Filing?

Do I have to file a DC income tax return?

You must file a DC tax return if:

• You were a resident of the District of Columbia and you were required to file a federal tax return. (A resident is an individual domiciled in DC at any time during the taxable year);
• You maintained a place of abode in DC for a total of 183 days or more even if your permanent home was outside of DC;
• If you want to receive a refund of DC taxes withheld during the year, or if you qualify for and want to receive the following refundable credits:
  • The DC Earned Income Tax Credit;
  • Schedule N, Non-Custodial Parent Earned Income Tax Credit;
  • Schedule H, Homeowner and Renter Property Tax Credit; or
  • Schedule ELC, Keep Child Care Affordable Tax Credit (formerly Early Learning Tax Credit).

Here's more detailed info from DC Office of Revenue.
