You are a Maryland resident if you are domiciled there, or if you keep a place of abode for more than six months and are present 183 or more days. Maryland counts any part of a day, with one nuance worth knowing.

The statutory residency test

Maryland’s statutory test runs alongside domicile: keep a place to live in the state for more than half the year, spend 183 or more days there, and Maryland taxes you as a resident even if your legal home is elsewhere. Meet both parts and the state does not care where you say you live.

The 24-hour wrinkle

Any part of a day in Maryland counts as a day, but a single continuous stay of less than 24 hours counts as only one day even if it spans two calendar dates, and time merely passing through is excluded. It is a small mercy, and it is exactly the kind of detail that decides a close case.

In an audit the burden is on you to prove the days you were outside the state. A contemporaneous day-by-day log, backed by phone, card, and travel records, is the strongest defense.

Every Maryland day counts. Track them cleanly.
