A taxpayer is considered a nonresident of the District of Columbia if their permanent home was outside of the District of Columbia for the entire year and they maintained a place of abode in the District of Columbia for fewer than 183 days during the year.
A taxpayer working in the District of Columbia but residing in another state is not subject to DC income tax, thus the District of Columbia does not have a nonresident income tax return.
A nonresident may request a refund of DC tax erroneously withheld or DC estimated payments made in error by filing Form D-40B, Nonresident Request for Refund. This form cannot be electronically filed. It must be printed and mailed.
