What Is a Registered Agent for a New Hampshire LLC?
A registered agent is the person or entity officially designated to accept service of process, government correspondence, and legal notices on behalf of a New Hampshire LLC. Under RSA 304-C:37, a limited liability company’s registered agent “is the limited liability company’s agent for service of process, notice, or demand required or permitted by law to be served on the limited liability company.” The role is narrow and specific: the agent receives lawsuits, tax notices, annual report reminders, and other official documents, then forwards them to the LLC. A registered agent does not manage the LLC’s affairs, provide legal counsel, or file taxes on the company’s behalf. The agent’s sole statutory function is to stand as a reliable point of contact between the state and the LLC, ensuring that time-sensitive legal documents reach the company without delay.
The physical address where the registered agent receives documents is called the registered office. New Hampshire law treats the registered agent and registered office as inseparable — the agent must be located at the registered office, and the two addresses must always match in the state’s records.
Is a Registered Agent Required for a New Hampshire LLC?
Every New Hampshire LLC must designate and continuously maintain a registered agent and registered office in the state. RSA 304-C:36 provides that “each limited liability company shall have and maintain in the state of New Hampshire” both a registered office and a registered agent. This requirement applies to domestic LLCs formed under RSA 304-C, foreign LLCs registered to transact business in the state under RSA 304-C:175, and professional limited liability companies (PLLCs) formed under RSA 304-D. The word “maintain” is significant — the obligation is continuous, not one-time. If the LLC ever finds itself without a registered agent or registered office for 60 days or more, the Secretary of State may begin proceedings to dissolve the company under RSA 304-C:136 administratively. For a foreign LLC, the equivalent consequence is revocation of its registration to do business in New Hampshire under RSA 304-C:183.
The registered agent must be named in the LLC’s initial formation filing and updated in every annual report filed with the Secretary of State. The annual report, due between January 1 and April 1 each year, must include “the address of its registered office and the name of its registered agent at that office” under RSA 304-C:194.
Who May Serve as a Registered Agent for a New Hampshire LLC?
New Hampshire limits registered agent eligibility to individuals and certain business entities that maintain a physical presence in the state. RSA 304-C:36, I(b) sets out four categories of eligible agents:
Option A — An Individual. Any individual who resides in New Hampshire and whose residential or business office address is identical to the registered office may serve as the LLC’s registered agent. There is no minimum age specified in the statute, and the individual does not need to be an attorney or hold any professional license.
Option B — A New Hampshire Corporation. A corporation organized or authorized under RSA 292, RSA 293-A, or RSA 294-A whose business office is identical to the registered office may serve.
Option C — A Limited Liability Company. An LLC formed or authorized under RSA 304-C, or a PLLC formed or authorized under RSA 304-D, whose business office is identical to the registered office, may serve. However, an LLC cannot appoint itself as its own registered agent — the agent must be a separate person or entity.
Option D — A Limited Liability Partnership. An LLP formed or authorized under RSA 304-A:44 whose business office matches the registered office may serve.
In all cases, the registered agent’s business or residential address must be identical to the LLC’s registered office address on file with the Secretary of State. The New Hampshire Secretary of State’s Registered Agents guidance page confirms that “a registered agent must be an individual, corporation, or LLC located in the state of New Hampshire” and that “the physical address of the registered agent is called the registered office.”
The table below summarizes which address types qualify as a registered office in New Hampshire.
| Address Type | Permissible as Registered Office |
| Physical street address in New Hampshire | Yes |
| Home address of an individual resident | Yes |
| Business office of a registered entity in NH | Yes |
| P.O. Box | No |
| Virtual office or mail-forwarding address without a staffed physical location | No |
| Address outside New Hampshire | No |
Note: The registered office cannot be a P.O. Box. The Secretary of State’s guidance page states that “a registered office is the physical business address in New Hampshire of the registered agent; it cannot be a post office box.” If the agent maintains both a P.O. Box and a street address, only the street address satisfies the requirement.
Can an LLC Member or Manager Serve as Registered Agent in New Hampshire?
Any LLC member, manager, or employee may serve as the company’s registered agent, provided they meet the individual eligibility requirements of RSA 304-C:36. In practical terms, this means the person must reside in New Hampshire and list a residential or business office address that matches the LLC’s registered office. No separate consent form is filed with the state for the initial designation — the agent is named directly in the certificate of formation, and the form is signed by an authorized person. New Hampshire’s Registered Agents page confirms that “individuals, business owners, managers, or employees can be listed as the registered agent for the business as long as they can be located at the registered agent address in this state.”
The decision to serve as one’s own registered agent is straightforward on paper but involves trade-offs in practice. The table below compares self-service and professional registered agent options across key factors.
| Factor | Serving as Own Agent | Professional Registered Agent Service |
| Cost | No additional fee beyond state filings | Annual service fee (varies by provider) |
| Privacy | The member’s personal or business address appears in public filings | The service provider’s address appears instead |
| Availability | Must be present at the registered office during business hours | Staffed office ensures consistent availability |
| Flexibility | Address changes require a $15 filing with the Secretary of State | Provider handles address logistics internally |
| Document handling | Member receives legal process directly, including in front of clients or coworkers | Provider receives the process discreetly and forwards it promptly |
| Multi-state operations | Must separately arrange an agent in each state | Many providers offer multi-state coverage |
How to Designate a Registered Agent on Your New Hampshire LLC Certificate of Formation
A New Hampshire LLC designates its registered agent and registered office in the certificate of formation filed with the Secretary of State. Under RSA 304-C:31, the certificate of formation must include “the address of the registered office and the name and address of the registered agent for service of process required to be maintained by RSA 304-C:36.” This information is not optional — the Secretary of State will not accept a certificate of formation that omits the registered agent designation. The designation appears in Article Third of Form LLC-1 for a domestic LLC, and an equivalent article of Form FLLC-1 for a foreign LLC registration.
Follow these steps to designate a registered agent during formation:
- Confirm that the intended agent meets the eligibility requirements of RSA 304-C:36 — either an individual residing in New Hampshire or an eligible business entity with a New Hampshire business office.
- Obtain the agent’s agreement to serve before filing. Although New Hampshire does not require a separate consent form, the agent’s name and address will become part of the public record upon filing.
- Complete Article Third of the applicable formation form with the registered agent’s full legal name and the registered office street address. If a P.O. Box is provided, a physical street address must also be included.
- Submit the completed form to the Corporation Division of the New Hampshire Department of State by mail to 107 N Main St, Rm 204, Concord, NH 03301-4989, or file online through the QuickStart portal.
- Pay the applicable filing fee. Online filings carry an additional $2 electronic handling charge under RSA 5:10-a.
The table below cross-references the formation and registration forms with their applicable entity types and fees.
| Form | Entity Type | Purpose | Filing Fee |
| Form LLC-1 | Domestic LLC | Certificate of Formation | $100 |
| Form PLLC-1 | Domestic PLLC | Certificate of Formation | $100 |
| Form FLLC-1 | Foreign LLC | Application for Registration | $100 |
| Form FPLLC-1 | Foreign PLLC | Application for Registration | $100 |
The table below compares the available filing methods.
| Filing Method | Available? | Details |
| Online (QuickStart portal) | Yes | An additional $2 electronic handling charge applies |
| Yes | Mail to Corporation Division, NH Dept. of State, 107 N Main St, Rm 204, Concord, NH 03301-4989 | |
| In-person | Yes | State House Annex, 3rd Floor, Rm 317, 25 Capitol St, Concord, NH; expedited processing available for a $25 fee |
Note: The QuickStart portal currently shows average processing times of 15–18 business days for online filings. In-person filings may be expedited for the additional fee noted above.
Registered Agent Information in Your LLC Operating Agreement
New Hampshire law treats the operating agreement as the primary private governance document for an LLC, and it is not filed with the Secretary of State. Under RSA 304-C:40, an operating agreement may be “written, oral, or implied by course of dealing or otherwise,” and it governs the LLC’s internal affairs, including management structure, profit allocation, and member rights. The registered agent, however, is not required by statute to be identified in the operating agreement — the official designation is made in the certificate of formation, and any change is made by filing Form 10 with the Secretary of State.
That said, many LLC owners choose to reference the registered agent in their operating agreement for practical reasons. Including the agent’s name and address gives members a single internal document that records the company’s key contacts and compliance obligations. The operating agreement can also establish a procedure for how and when the registered agent may be changed, who is responsible for monitoring the agent’s continued eligibility, and how members will be notified of a change. These internal provisions create accountability without adding any filing obligation — they simply supplement the official public record.
Updating the registered agent’s name or address in the operating agreement alone does not constitute an official change. A separate filing with the Secretary of State is always required to change the registered agent or registered office on the state’s records.
What Happens to a New Hampshire LLC Without a Registered Agent?
A New Hampshire LLC that fails to maintain a registered agent or registered office faces administrative dissolution. Under RSA 304-C:136, the Secretary of State may administratively dissolve an LLC if it “is without a registered agent or registered office in this state for 60 days or more” or if it “does not notify the secretary of state within 60 days that its registered agent or registered office has been changed, that its registered agent has resigned, or that its registered office has been discontinued.” The 60-day window is the LLC’s effective cure period — once it passes, the Secretary of State may proceed with dissolution.
When the Secretary of State determines that grounds for dissolution exist, the process under RSA 304-C:137 begins with a signed notice of dissolution mailed to the LLC at its principal address, along with an application for reinstatement. The notice recites the specific grounds and the effective date of dissolution. After dissolution, the LLC’s name is protected for 120 days — the Secretary of State will not allow another entity to assume the same or a similar name during that period.
For foreign LLCs, the consequence under RSA 304-C:183 is revocation of registration rather than dissolution. If the foreign LLC is without a registered agent or registered office for 60 days or more, the Secretary of State sends written notice and gives the LLC 60 days to correct the deficiency. If uncured, the registration is revoked, and the LLC loses its authority to transact business in New Hampshire.
The table below summarizes the consequences of failing to maintain a registered agent.
| Consequence | Authority |
| Administrative dissolution (domestic LLC) after 60 days without an agent | RSA 304-C:136, III |
| Revocation of registration (foreign LLC) after 60 days without an agent | RSA 304-C:183, III |
| Bypass of registered agent for service of process — service by certified mail to the LLC’s principal office | RSA 304-C:37, II |
| Secretary of State becomes substitute agent for unregistered foreign LLCs doing business in the state | RSA 304-C:182, I |
| Foreign LLC barred from maintaining actions in New Hampshire courts until it registers and pays all fees | RSA 304-C:180, I |
| LLC name protected for 120 days following administrative dissolution | RSA 304-C:137, III |
Reinstatement. A domestically dissolved LLC may apply for reinstatement within three years of the effective date of dissolution under RSA 304-C:138. The application must state that the grounds for dissolution have been eliminated, confirm that the LLC’s name is available, and include a certificate from the New Hampshire Department of Revenue Administration if filed more than 120 days after the dissolution notice was mailed. The reinstatement fee is $135 under RSA 304-C:191, II(f). If more than three years have passed, the LLC may apply for late reinstatement under RSA 304-C:145 at a fee of $500, which also requires publication of notice. When reinstatement takes effect, it relates to the date of dissolution, and the LLC resumes business as if the dissolution had never occurred.
How to Change a Registered Agent for a New Hampshire LLC
An LLC changes its registered agent or registered office by filing Form 10 — Statement of Change of Registered Office or Registered Agent, or Both with the Secretary of State. RSA 304-C:36, II authorizes the filing and specifies the required contents: the LLC’s name, the current registered office address, the new registered office address (if changing), the current agent’s name and address, the new agent’s name and address (if changing), and a confirmation that the registered office and the agent’s business address will remain identical after the change. The filing fee is $15 under RSA 304-C:191, II(b). Form 10 is the same form used by corporations, LLPs, and foundations — it covers all entity types.
Follow these steps to change the registered agent:
- Confirm that the new agent meets the eligibility requirements under RSA 304-C:36, I(b) — either a New Hampshire resident individual or an eligible business entity with a New Hampshire business office.
- Notify the new agent and obtain their agreement to serve before filing.
- Complete Form 10 with the LLC’s name as it appears in the Secretary of State’s records, the current agent information, and the new agent information.
- Sign the form. Under Form 10’s instructions, it must be executed by “an officer or director, a manager or member, a partner, founder, or agent.”
- Submit the form online through QuickStart or by mail to the Corporation Division at 107 N Main St, Rm 204, Concord, NH 03301-4989, along with the $15 filing fee.
If a registered agent resigns, they file a written notice of resignation with the Secretary of State under RSA 304-C:36, III. The Secretary of State mails a copy of the resignation notice to the LLC at its principal office. The agent’s appointment terminates 31 days after the resignation is filed or upon the appointment of a successor agent, whichever comes first. If the LLC does not appoint a new agent within 60 days after the registered office is discontinued, it risks administrative dissolution under RSA 304-C:136.
Note: A registered agent who moves to a new address within New Hampshire may file a change of address for any LLC it represents without requiring the LLC itself to sign. Under RSA 304-C:36, V, the agent files a statement containing the new address, signed only by the agent, along with confirmation that a copy has been mailed to the LLC. The fee is $15 per filing.
New Hampshire LLC Registered Agent Frequently Asked Questions
Can a New Hampshire LLC serve as its own registered agent?
No. Under RSA 304-C:36, I(b), the registered agent must be a separate individual or entity — specifically, an individual resident, a corporation, a different LLC or PLLC, or an LLP. The statute lists “a limited liability company formed or authorized under this act” as an eligible agent category, meaning one LLC can serve as the registered agent for another LLC, but the statute’s structure requires the agent to be a distinct person or entity from the LLC being served. The New Hampshire Secretary of State’s Registered Agents page lists categories of eligible agents and does not include self-designation. A member, manager, or employee of the LLC may serve individually, but the LLC entity itself cannot appoint itself.
Can a single-member LLC owner serve as the LLC’s registered agent?
Yes. A single-member LLC owner who is an individual residing in New Hampshire may serve as the registered agent, provided their residential or business office address is used as the registered office. This is the most common arrangement for small, owner-operated businesses. The owner’s name and address will appear in the public record — both in the certificate of formation and in each annual report filed with the Secretary of State. Business owners who prefer to keep their home address out of the public record often engage a professional registered agent service, whose commercial address appears in filings instead.
Does a multi-member LLC need a registered agent separate from its members?
No. New Hampshire does not require a multi-member LLC to appoint an outside agent. Any individual member who resides in the state and maintains a qualifying address may serve. The members should, however, agree in the operating agreement on who will serve and what process will be followed if that person resigns, relocates, or becomes unavailable. When multiple members have New Hampshire addresses, any one of them may be designated. A professional service becomes practical when no member resides in the state or when the members prefer to keep their personal addresses out of the LLC’s public filings.
Is it required to designate a registered agent prior to submitting the formation documents for a business entity?
Yes. Under RSA 304-C:31, II(b), the certificate of formation must include “the address of the registered office and the name and address of the registered agent for service of process.” This is a mandatory field on Form LLC-1, and the Secretary of State will not accept a certificate that omits it. The agent should be identified and should agree to serve before the organizer files the formation documents. The same requirement applies to foreign LLCs registering on Form FLLC-1 and to PLLCs filing on Form PLLC-1.
Is the LLC’s registered agent required to be listed in the operating agreement?
No. New Hampshire law does not require the registered agent to be identified in the operating agreement. The official designation is made in the certificate of formation filed with the Secretary of State, and changes are made by filing Form 10. Under RSA 304-C:40, the operating agreement governs the LLC’s internal affairs and may be written, oral, or implied. Because the operating agreement is a private document not filed with the state, including the registered agent’s information in it is optional — useful for internal reference, but not a substitute for the official filing.
Can I change my LLC’s registered agent online?
Yes. New Hampshire’s QuickStart portal allows LLCs to file Form 10 electronically. The filing fee is $15, plus a $2 electronic handling charge for online transactions. The change takes effect when the Secretary of State processes and files the document. Paper filings may also be submitted by mail or delivered in person to the Corporation Division in Concord.
Does a Professional LLC (PLLC) have different registered agent requirements?
No. A New Hampshire PLLC formed under RSA 304-D is subject to the same registered agent and registered office requirements as a standard LLC. RSA 304-D:4 provides that a PLLC “shall have the powers enumerated in the laws of this state applicable to limited liability companies,” and RSA 304-C:36 applies to PLLCs through this incorporation by reference. The distinguishing features of a PLLC relate to member licensing, permissible purposes, and professional liability — not to registered agent obligations. PLLCs file Form PLLC-1 for formation and use the same Form 10 to change their agent.
Can the same individual or service act as registered agent for multiple New Hampshire LLCs?
Yes. No provision of RSA 304-C limits the number of LLCs for which an individual or entity may serve as registered agent. Professional registered agent companies in New Hampshire routinely represent hundreds of entities. When a single agent represents multiple LLCs and needs to update their own address, they may file a Form 10 for each entity under RSA 304-C:36, V, signed only by the agent, with a $15 fee per entity. There is no consolidated multi-entity change form in New Hampshire — each LLC requires its own filing.
What happens if my LLC’s registered agent moves out of New Hampshire?
The LLC must promptly appoint a replacement agent who meets the in-state eligibility requirements. An agent who no longer resides in New Hampshire or maintains a New Hampshire business office no longer satisfies RSA 304-C:36, I(b). If the agent formally resigns under RSA 304-C:36, III, the LLC has until the earlier of the 31st day after filing of the resignation or the appointment of a successor to make the change. If the LLC remains without a registered agent or registered office for 60 days or more, the Secretary of State may begin administrative dissolution proceedings under RSA 304-C:136. Filing Form 10 to appoint a new agent as quickly as possible avoids any lapse in compliance.
