Plate Nº 21 of 51 — MD
Maryland
Maryland keeps the national pattern with its own hand on the chart: the role here is called the resident agent, and the filings live with the State Department of Assessments and Taxation (SDAT) — Charter Division.
The requirement in Maryland
Every LLC, corporation, and — in most cases — limited partnership or registered nonprofit formed in Maryland must continuously maintain a resident agent and a registered office in Maryland, from the day the formation is filed until the day the entity is dissolved. The duty also attaches to out-of-state companies that qualify to do business in Maryland: foreign qualification and the appointment of a resident agent are filed together, and neither works without the other.
The registered office must be a physical street address in Maryland where the agent can be found during normal business hours. It is published in the state's business record — which is why whose address it is becomes a privacy decision as much as a legal one.
Who may serve in Maryland
Two kinds of agent are recognized: an individual — an adult resident of Maryland with a physical address there — and a business entity authorized to do business in Maryland whose office is the registered office. You, a co-owner, or an employee can serve if you meet the individual test. A commercial agent meets the entity test and sells the standing. In a growing number of states the agent must formally consent to the appointment; everywhere, an agent who has not agreed to serve is a coverage failure waiting for its first lawsuit.
Changing course in Maryland
Agents are changed by filing a change of resident agent / registered office with the State Department of Assessments and Taxation (SDAT) — Charter Division — the office publishes the current form and any fee on its own schedule. The safe sequence never changes: the new appointment takes effect first, the old agent's resignation follows, and you confirm the change in the public record before you consider it done.
An agent may also resign on their own initiative. How a resignation takes effect, and how long you then have to name a successor, are set by Maryland law and differ from state to state — what does not differ is that the seat cannot sit empty on paper while the company trades. Treat a resignation letter as a deadline, and file the change immediately.
Reports and the agent in Maryland
Maryland's annual report rides with the personal property return filed with SDAT — the filing that keeps both the entity and its resident agent current.
Verify the agent of record
Do not take any plate's word for your own record — check it. Search your entity by name in the State Department of Assessments and Taxation (SDAT) — Charter Division's official business database and read the agent and address exactly as filed: the official entity search. If what is filed is not who would actually be standing there on a Tuesday, file the change before anything else on your list.

- Decide whose address goes on the public record — the DIY ledger is honest about the trade.
