Short answer. District of Columbia doesn't list partner states. Its Form D-4A lets any nonresident tell the employer not to withhold: Anyone who isn't a DC resident files it with the employer to establish that they aren't subject to DC income tax withholding.

"If you are not a resident of DC you must file a Form D-4A"
In the official words
"with your employer to establish that you are not subject to DC income tax withholding."
Credit for tax paid to other states
DC domiciliary taxpayers can claim a credit for individual income tax paid to other states on Schedule U (Calculation K); "The credit is limited to the rate of tax charged in the District." From the 2022 D-40 instructions, the latest booklet we could open.
Worth knowing
- Form D-4A treats you as a nonresident when your permanent residence is outside DC all year and you don't reside in DC 183 days or more in the year. The form we opened is revised 02/2015.
- The D-4A doesn't name partner states; it covers every nonresident. Maryland and Virginia list DC among their reciprocal agreements.
- A nonresident with DC tax withheld gets it back on Form D-40B, Non-Resident Request for Refund. The 2024 D-40B defines a nonresident as anyone whose permanent home was outside DC all year and who did not keep a place of abode in DC for 183 days or more.
Not confirmed on the pages we read: a convenience of the employer rule, a days-in-state threshold.
