What Is a Registered Agent for a Maryland LLC?
A resident agent is an individual or entity officially designated to accept service of process and legal notices on behalf of a Maryland limited liability company. Maryland uses the term resident agent rather than “registered agent,” but the function is the same — the resident agent serves as the LLC’s point of contact for lawsuits, state correspondence, and formal demands. Under Corporations and Associations Article §1-401, service of process on the resident agent “constitutes effective service of process” on the LLC in any pending, filed, or instituted action under the Corporations and Associations Article. The resident agent’s role is strictly limited to receiving legal documents and forwarding them to the LLC — it does not include managing the business, providing legal advice, or acting as a general representative in commercial transactions. Every LLC that files articles of organization with the Maryland State Department of Assessments and Taxation (SDAT) must name a resident agent in the filing itself, and that person or entity remains publicly identified in the state’s records.
Is a Registered Agent Required for a Maryland LLC?
Every Maryland LLC must have a resident agent. Under Corporations and Associations Article §4A-210, “each limited liability company shall have … a resident agent.” This requirement applies to domestic LLCs formed under the Maryland Limited Liability Company Act (Title 4A), foreign LLCs registered to do business in Maryland under §4A-1002, and LLCs formed to provide professional services. The obligation is continuous — the LLC must maintain a resident agent from the date the articles of organization are accepted for record through the date of cancellation or dissolution. A lapse in resident agent coverage, combined with a failure to file the required annual report (Personal Property Return), can result in forfeiture of the LLC’s right to do business in Maryland under §4A-911.
Note: Maryland also requires every LLC to maintain a principal office in the state. Both the principal office address and the resident agent’s address must be physical street addresses — P.O. Boxes are not accepted for either.
Who May Serve as a Registered Agent for a Maryland LLC?
Maryland law limits resident agent eligibility to two categories of persons. The SDAT instructions for Articles of Organization specify that “a resident agent can be any Maryland citizen who is over eighteen, a Maryland corporation, or a Maryland LLC.” The definition in §1-101(x) of the Corporations and Associations Article confirms that a resident agent is “an individual residing in this State or a Maryland corporation, limited liability company, or limited partnership whose name, address, and designation as a resident agent are filed or recorded with the Department.” The resident agent’s address cannot be a P.O. Box.
Option A — An Entity. A Maryland corporation, Maryland LLC, or Maryland limited partnership may serve as a resident agent for another LLC. The entity must be organized or registered in Maryland — a foreign entity not qualified in the state does not qualify. The entity that serves as the resident agent cannot be the LLC itself.
Option B — An Individual. Any individual who is a citizen and resident of Maryland and is at least eighteen years old may serve as a resident agent. The individual must maintain an address in Maryland (not a P.O. Box) where process can be delivered.
The resident agent must consent to the appointment. Both the Articles of Organization and the Resolution to Change Principal Office or Resident Agent include a separate signature line where the resident agent signs to indicate consent.
| Registered Office Requirement | Permissible | Not Permissible |
| Physical street address in Maryland | Yes | — |
| P.O. Box as sole address | — | Not permissible |
| Address outside Maryland | — | Not permissible |
| Virtual office with no physical presence | — | Not permissible |
| Residential address of a Maryland resident | Yes | — |
Can an LLC Member or Manager Serve as Registered Agent in Maryland?
Yes, any LLC member, manager, or authorized person who is at least eighteen years old and resides in Maryland may serve as the LLC’s resident agent. There is no statutory prohibition against a member or manager filling this role — the only requirements are Maryland residency, legal age, and a physical Maryland address. The member or manager signs the resident agent consent line on the Articles of Organization, and their name and address become part of the public record maintained by SDAT. This is the simplest and least expensive approach, but it carries practical trade-offs that every LLC organizer should evaluate before making the designation.
| Factor | Serving as Own Agent | Professional Resident Agent Service |
| Privacy | The member’s or manager’s name and personal address appear in SDAT’s public records | The service’s business name and address appear instead |
| Availability | The agent must be available at the Maryland address during business hours to accept service | Professional service maintains staffed offices for consistent availability |
| Flexibility | If the agent moves out of Maryland, the LLC must immediately file a change | Service maintains a stable Maryland address regardless of the member’s personal moves |
| Document handling | The agent receives the process directly and must forward it to the LLC promptly | Service receives, logs, and forwards documents according to established procedures |
| Professionalism | Service of a lawsuit at a home address may feel intrusive | A dedicated business address creates a more formal point of contact |
How to Designate a Registered Agent on Your Maryland LLC Certificate of Formation
The resident agent is designated on the LLC’s Articles of Organization, which is the foundational document filed with SDAT to create the LLC. Under §4A-204, the articles of organization must include “the name and address of its resident agent.” This information appears in Item (4) of the Articles of Organization form. The resident agent must also sign the document in Item (6), confirming consent to the appointment.
The designation process follows these steps:
- Identify a qualifying resident agent — a Maryland citizen who is at least eighteen years old, or a Maryland corporation, LLC, or limited partnership. Confirm the agent’s willingness to serve and obtain their agreement to sign the filing.
- Complete Item (4) of the Articles of Organization with the resident agent’s full name and physical street address in Maryland (no P.O. Box).
- Complete Item (3) with the LLC’s principal office address in Maryland (also no P.O. Box).
- Have the resident agent sign in Item (6) and an authorized person sign in Item (5).
- Submit the completed Articles of Organization with the $100 filing fee. Filing may be completed online through Maryland Business Express, by mail to SDAT Charter Division, 700 East Pratt Street, Suite 2700, Baltimore, MD 21202, or by hand-delivery to the drop boxes at 123 Market Place, Baltimore, MD 21202.
Note: Standard processing for non-expedited filings is 6 to 8 weeks. Expedited review (7 to 10 business days) requires an additional $50 fee. Same-day processing is available at an additional cost of $325 for online filings or $425 for hand-delivered filings. Online payments through Maryland Business Express include a 3% service/convenience fee.
Maryland uses the same Articles of Organization form for standard LLCs and professional LLCs. A foreign LLC registers using a separate form. The table below summarizes each filing:
| Filing | Form | Entity Type | Filing Fee |
| Articles of Organization | Articles of Organization | Domestic LLC (including Professional LLC) | $100 |
| Limited Liability Company Registration | LLC Registration (Foreign) | Foreign LLC | $100 |
| Resolution to Change Resident Agent | Resolution to Change | Domestic or Foreign LLC (change after formation) | $25 |
Registered Agent Information in Your LLC Operating Agreement
The operating agreement is the private agreement governing the internal affairs of a Maryland LLC. Under §4A-101(q), the operating agreement is “the agreement of the members and any amendments thereto concerning the matters described in §4A-402(a).” Section 4A-402 establishes the broad scope of subjects the operating agreement may address — management structure, profit sharing, membership rights, and amendment procedures — but does not require inclusion of the resident agent designation. The resident agent is officially designated through the articles of organization filed with SDAT, not through the operating agreement.
The operating agreement is a private document that is not filed with the state. Unless the articles of organization specifically require otherwise, the operating agreement does not even need to be in writing under Maryland law. An LLC may choose to reference the resident agent in its operating agreement for internal reference — to clarify which individual or entity is currently serving, to establish a procedure for notifying members of a planned change, and to set out how a successor agent will be selected. Updating the resident agent information in the operating agreement alone, however, does not change the official designation. A filing with SDAT — either a Resolution to Change Resident Agent or the Resident Agent’s Notice of Change of Address — is always required to make the change effective on the state’s records.
What Happens to a Maryland LLC Without a Registered Agent?
A Maryland LLC that fails to maintain a resident agent — or that fails to file its annual Personal Property Return — risks forfeiture of its right to do business in the state. Maryland’s consequence mechanism operates differently from many states: rather than administrative dissolution triggered solely by loss of a resident agent, forfeiture in Maryland is typically proclaimed by SDAT under §4A-911 after a failure to file the annual report, pay required taxes, or pay unemployment insurance contributions. The Department certifies a list of noncompliant LLCs after September 30 each year and issues a proclamation declaring that “the right to do business in Maryland and the right to the use of the name for each limited liability company is forfeited as of the date of the proclamation.” Under §4A-912, the LLC has 60 days after the proclamation to come into compliance and have its rights reinstated automatically.
If the LLC has no resident agent and cannot be served through one, the Maryland Rules allow service by other means. For a foreign LLC, the registration form itself states that SDAT “is appointed as the resident agent of the foreign limited liability company if no resident agent has been appointed … or, if appointed, the resident agent’s authority has been revoked or if the agent cannot be found or served with the exercise of reasonable diligence.”
| Consequence | Authority |
| LLC’s right to do business in Maryland is forfeited | §4A-911 |
| LLC loses the right to the use of its name | §4A-911 |
| SDAT becomes substitute agent for service of process on a foreign LLC without a resident agent | §4A-1002 |
| Risk of default judgment if the LLC does not receive notice of a lawsuit | Practical consequence of failed service |
Reinstatement requires filing the Articles or Certificate of Reinstatement with SDAT, naming a new resident agent (who must sign the form), paying a $100 filing fee for standard processing (or $150 for expedited), and resolving all delinquent annual reports and outstanding tax obligations. If the forfeiture was caused by unpaid taxes, the LLC must also obtain a tax clearance certificate from the appropriate county or city before SDAT will process the reinstatement.
How to Change a Registered Agent for a Maryland LLC
A Maryland LLC changes its resident agent by filing a Resolution to Change Principal Office or Resident Agent with SDAT. Under §4A-210(b), the LLC may designate or change its resident agent “by filing for record with the Department a statement signed by an authorized person which authorizes the designation or change.” The change is effective when SDAT accepts the statement for record. The filing fee is $25 per entity.
The process follows these steps:
- Identify the new resident agent and confirm their eligibility — a Maryland citizen over eighteen, or a Maryland corporation, LLC, or limited partnership.
- Complete the Resolution form with the entity’s name, the old and new resident agent’s name and address, and any changes to the principal office if applicable.
- Have the new resident agent sign the consent line on the form.
- Have an authorized person of the LLC sign the form.
- Submit the form with the $25 filing fee. The Resolution to Change Resident Agent may be submitted online through Maryland Business Express or by mail to SDAT, 700 East Pratt Street, Suite 2700, Baltimore, MD 21202.
If a resident agent changes their own address — rather than the LLC appointing a different agent — the agent files a separate Resident Agent’s Notice of Change of Address directly with SDAT. The fee is also $25 per entity. The agent must notify the LLC in writing of the change. If the agent’s old and new addresses are the same as the LLC’s old and new principal office address, the address change form may include a simultaneous change of principal office, provided the statement recites that written notice was sent to the LLC.
A resident agent may resign at any time by filing a signed resignation with SDAT. Under §4A-210(d), the resignation is effective immediately if the LLC has already appointed a successor agent, or 10 days after filing if no successor has been appointed. There is no filing fee for a resignation.
Maryland LLC Registered Agent Frequently Asked Questions
Can a Maryland LLC serve as its own registered agent?
No. A Maryland LLC cannot designate itself as its own resident agent. Under §1-101(x), a resident agent must be “an individual residing in this State or a Maryland corporation, limited liability company, or limited partnership” — meaning a separate individual or entity, not the LLC being represented. The SDAT Articles of Organization form describes the resident agent as “another entity or individual designated to accept service of process for the LLC.” The LLC must appoint a distinct qualifying person or entity to serve in this capacity.
Can a single-member LLC owner serve as the LLC’s registered agent?
Yes. A single-member LLC owner who is a Maryland resident and at least eighteen years old may serve as the LLC’s resident agent. The owner’s name and address become part of the public record filed with SDAT when the Articles of Organization are accepted. The owner signs the resident agent consent line (Item 6) on the formation form. The single-member owner should consider whether listing a personal address — which must be a physical street address, not a P.O. Box — in SDAT’s public database is acceptable from a privacy standpoint.
Does a multi-member LLC need a registered agent separate from its members?
No. Maryland does not require a multi-member LLC to appoint a resident agent who is independent of the LLC’s membership. Any member who is a Maryland citizen, at least eighteen years old, and has a physical street address in Maryland may serve. The LLC may also appoint a Maryland corporation, LLC, or limited partnership as its agent. Multi-member LLCs with members in different states, or those seeking to keep personal addresses off the public record, may find it more practical to engage a professional resident agent service. The agent designation can be changed at any time by filing the Resolution to Change Resident Agent for $25.
Is it required to designate a registered agent prior to submitting the formation documents for a business entity?
Yes. Under §4A-204, the articles of organization must include “the name and address of its resident agent.” SDAT will not accept articles of organization that omit this information. The resident agent must also sign the Articles of Organization form to indicate consent before the document is submitted. This means the LLC organizer must identify and secure the agreement of a qualifying resident agent before filing the formation document with SDAT.
Is the LLC’s registered agent required to be listed in the operating agreement?
No. Maryland’s Limited Liability Company Act does not require the operating agreement to identify the resident agent. Under §4A-402, the operating agreement may address a broad range of internal matters, but the resident agent is officially designated through the articles of organization filed with SDAT. The operating agreement is a private document — and in Maryland, it is not even required to be in writing unless certain conditions apply. An LLC may include the resident agent’s identity in its operating agreement for the members’ convenience, but only a filing with SDAT makes a change effective.
Can I change my LLC’s registered agent online?
Yes. Maryland offers online filing for a change of resident agent through Maryland Business Express. The LLC selects “Resolution to Change Resident Agent” from the list of available changes. The filing fee is $25 per entity, plus the 3% online convenience fee. The change is effective when SDAT accepts the filing for record. The same change may also be submitted by mail or hand-delivery using the paper Resolution form.
Does a Professional LLC (PLLC) have different registered agent requirements?
No. Maryland does not maintain a separate PLLC formation statute with distinct resident agent obligations. Professional LLCs use the same Articles of Organization form as any other domestic LLC, and the resident agent requirements under §4A-210 apply identically. The distinctions for professional LLCs involve licensing requirements and permitted types of professional services — as defined in §4A-101(t) — not the rules governing the resident agent designation, consent, or address.
Can the same individual or service act as registered agent for multiple Maryland LLCs?
Yes. Maryland places no statutory limit on the number of LLCs for which an individual or entity may serve as resident agent. A person serving as agent for multiple entities should be aware that each change of address requires a separate Resident Agent’s Notice of Change of Address for each LLC, at $25 per entity. Professional resident agent services that represent large numbers of entities manage this process as part of their standard operations, filing address changes in bulk when their office location shifts.
What happens if my LLC’s registered agent moves out of Maryland?
The resident agent no longer qualifies because Maryland requires the agent to be “an individual residing in this State” under §1-101(x). The LLC must promptly appoint a replacement by filing the Resolution to Change Resident Agent with SDAT and paying the $25 filing fee. The departing agent may also file a resignation directly with SDAT. If the LLC fails to appoint a successor, service of process may be attempted through other means permitted under the Maryland Rules, and the LLC’s inability to receive legal documents could lead to a default judgment. For a foreign LLC, SDAT automatically becomes the fallback agent for service of process if no agent is on record or the named agent cannot be found or served.
