Moved from DC to MD

Hi everyone,

 

I moved from DC to MD in April of 2022 but worked in Maryland all year. I was planning to file a part year DC and part year MD tax return but I’m being told I may need to file a part year DC, part year MD, AND nonresident MD tax return since I earned MD income while living in DC. Essentially this will make my income earned while living in DC taxed twice, once on my DC part year tax form and again on my MD nonresident tax form. I know MD and DC have a reciprocity agreement so I feel like I should not have to file a nonresident MD return but want to double check with the community here.
