Thanks that is what I thought but the Maryland nonresident instruction booklet (https://www.marylandtaxes.gov/forms/22_forms/Nonresident_Booklet.pdf) (page 1) states in their table: "Taxpayer who moved into or out of Maryland during the tax year and received income from Maryland sources while you were a nonresident of Maryland." should file "Form 505 Nonresident Return AND Form 502 Resident Return."
Does this not apply since DC and MD have reciprocity agreements? I can't find any source to state that this section doesn't apply for a move from DC to MD.
