I have the same problem. Resides in MD and employer took DC and MD taxes. What do I file in DC? Just D-40B Sub Nonresident request for refund? And then file the MD taxes for 100% of the income? Is there no reciprocal agreement between DC and MD that the refund passes through? I've been on hold with DC for a half and hour and still waiting.

It sounds like MD I should show the income as 100% from MD? Am I understanding correctly? Any help would be great.

thanks so much
