I'm helping my daughter with her taxes. She is a MD resident, owns a house in Baltimore, has a MD drivers license, and votes in MD, but she worked in DC all of 2024, sharing a DC apartment with her boyfriend (more than 183 days). Her W2 shows taxes paid to DC and Maryland. It looks like she has to file with both DC and MD, with DC saying she is a 'statutory resident' - but how does that work with her MD residency status? I see that there is reciprocity, but I don't understand how to file for it.
