Maryland Registered Agent Requirements 2026: Complete Guide
Quick Answer
Maryland requires every LLC to maintain a "resident agent" (Maryland's term for registered agent) with a physical Maryland street address. The agent can be an individual Maryland resident or a business entity authorized to do business in Maryland. Your resident agent must be available during normal business hours to accept service of process and official notices from the state. If you change your agent or address, update SDAT promptly to avoid missing legal documents and risking loss of good standing.

What a Resident Agent Does in Maryland
In Maryland, every LLC must designate a resident agent — this is Maryland's term for what most states call a "registered agent." The resident agent is your LLC's official contact for service of process (lawsuits), government correspondence, and other legal notices.
SDAT, courts, and regulatory agencies need a reliable in-state point of contact. If your agent is not available when documents are delivered, you can miss deadlines and create expensive legal problems — including default judgments.
The resident agent's name and address are listed on your LLC's formation documents and are publicly searchable through the Maryland Business Express database. This is why many business owners use a professional service rather than their home address.
Who Can Be a Resident Agent in Maryland?
Maryland law allows the following to serve as a resident agent:
- An individual Maryland resident (including you, a friend, family member, or business colleague) who has a physical Maryland address and accepts the appointment.
- A business entity authorized to transact business in Maryland (such as a commercial registered agent company, law firm, or accounting firm).
The resident agent must consent to the appointment. When filing your Articles of Organization, you'll include the agent's name and address, and the agent should be aware of and agree to this responsibility.
If you're not a Maryland resident, you usually cannot serve as your own resident agent. You'll need to appoint a qualifying Maryland-based individual or hire a registered agent service.
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.
Privacy Warning
Your resident agent address is public information, searchable through the Maryland Business Express database. If you use your home address, anyone can find it. A commercial resident agent service keeps your personal address private.
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
If you move, change agents, or your agent resigns, update your resident agent information with SDAT promptly. You can file the change through the Maryland Business Express online portal.
After updating, verify the change by searching for your LLC in the Maryland Business Express database. This confirms that your record is current and that SDAT and courts will use the correct address going forward.
If your resident agent resigns and you do not appoint a replacement, SDAT may not be able to deliver important compliance notices — which can trigger penalties and risk your LLC's good standing.
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
A commercial registered agent service for Maryland typically costs $100–$300/year. The tradeoff is privacy and consistent availability versus cost savings.
Being your own resident agent saves money, but only makes sense if you're a Maryland resident with a physical street address where you can reliably accept documents during business hours. If you work remotely, travel frequently, or run your business from home and value privacy, a professional service is usually the better choice.
