Maryland Resident Agent Requirements 2026: Rules + $25 Change Fee

Who Can Be a Resident Agent in Maryland?

SDAT's rule is narrow. A Maryland resident agent must be one of exactly two things:

• An individual who is a citizen of Maryland, resides in Maryland, and is at least 18 years old (this can be you, a member, or a trusted individual).
• An active Maryland corporation or Maryland LLC — for example, a commercial resident agent company, law firm, or accounting firm that is itself a registered Maryland entity.

Note what this excludes: an out-of-state company that is merely "authorized to do business" in Maryland does not qualify on its own, and your LLC cannot list itself as its own resident agent. The agent must consent to the appointment and sign the Articles of Organization, which is where you supply the agent's name and Maryland street address.

Can you be your own resident agent? Yes — if you are a Maryland resident with a physical street address where you can accept documents during business hours, you can name yourself. If you live outside Maryland, you cannot serve personally; you would appoint a qualifying Maryland individual or hire a Maryland resident agent service. Our companion guide, Can I be my own registered agent in Maryland?, walks through when DIY makes sense.

Address Rules (PO Box?)

Your Maryland resident agent address must be a physical street address in Maryland. PO Boxes are not acceptable because process servers and state officials need to physically deliver documents.

The address must be in Maryland — you cannot use an address in Virginia, D.C., or any other jurisdiction, even if it's nearby. This is a common issue for business owners in the D.C. metro area who may live in Virginia but operate their LLC in Maryland.

How to Change Your Resident Agent

To change agents or update the address, you file a Resolution to Change Principal Office or Resident Agent with SDAT. The fee is $25 (the same $25 covers a change of the agent's address). There is no fee for a resident agent to resign. You can file online through the Maryland Business Express portal or by mail; the new agent must consent and sign.

After filing, confirm the change by searching for your LLC in the Maryland Business Express database, so SDAT and courts use the correct address going forward. The annual Maryland LLC annual report (the $300 Personal Property Return due April 15) is filed in the same portal.

If your resident agent resigns and you do not appoint a replacement, SDAT cannot deliver compliance notices to you. Combined with a missed annual report, that leads to forfeiture of your right to do business in Maryland — loss of good standing and, ultimately, administrative dissolution.

Common Mistakes to Avoid

• Using an address where nobody is present during business hours (missed service can lead to default judgments).
• Using a Virginia or D.C. address instead of a Maryland address — common for D.C. metro area business owners.
• Not updating SDAT after moving or changing agents.
• Assuming email is enough — service of process is delivered physically in most cases.
• Letting the Annual Report lapse — commonly paired with missing compliance notices because the agent address is outdated.

Cost: DIY vs Resident Agent Service

Serving as your own resident agent costs nothing — Maryland charges no fee to name yourself at formation. A commercial Maryland resident agent service typically runs $100–$300/year (a market estimate, not a state fee). The tradeoff is privacy and consistent availability versus that annual cost.

DIY makes sense if you are a Maryland resident with a street address where you can reliably accept documents during business hours. If you work remotely, travel often, or run the business from home and value privacy, a paid service is usually the better fit. Either way, the only mandatory state cost tied to the agent is the $25 fee if you change agents later. See our Maryland LLC taxes and fees breakdown for the full cost picture.
