What Is a Connecticut Registered Agent?
A registered agent is a person or business entity officially designated to receive service of process, legal notices, and government correspondence on behalf of a business registered with the Connecticut Secretary of the State. Every domestic and foreign corporation, limited liability company, limited liability partnership, and statutory trust formed or authorized to transact business in Connecticut must name a registered agent at the time of formation or registration. Under Conn. Gen. Stat. § 33-660, each corporation that files annual reports must “continuously maintain in this state … a registered office” and “a registered agent at such registered office.” The Connecticut Uniform Limited Liability Company Act imposes a parallel requirement on LLCs through Conn. Gen. Stat. § 34-243n. The registered agent serves as the entity’s official point of contact with the state and the courts, ensuring that time-sensitive legal papers reach the business rather than going undelivered.
What Does a Connecticut Registered Agent Do?
A Connecticut registered agent accepts service of process and forwards it to the business entity. Under the Connecticut Business Corporation Act, the registered agent is “the corporation’s agent for service of process, notice or demand required or permitted by law to be served on the corporation.” This duty means the agent must be available at the registered office during regular business hours to accept lawsuits, subpoenas, tax notices, annual report reminders, and other official documents issued by Connecticut courts or state agencies.
Once a document is received, the agent’s responsibility is to forward it promptly to the entity’s officers, directors, or managers at their last known address. Timely forwarding is essential because many legal documents carry strict response deadlines. Missing a summons, for example, can result in a default judgment against the business.
The table illustrates the types of documents a registered agent typically handles:
| Document Type | Examples |
| Service of process | Lawsuits, summonses, subpoenas |
| State correspondence | Annual report reminders, compliance notices |
| Tax notices | Business entity tax reminders from the Department of Revenue Services |
| Administrative notices | Notices of intent to dissolve, revocation warnings |
Connecticut Registered Agent Requirements
Connecticut requires every registered agent to be either a natural person who is a resident of the state or an eligible business entity authorized to transact business in Connecticut. The agent must maintain a registered office — a physical street address in Connecticut where service of process can be delivered during business hours. P.O. Boxes are not acceptable as the primary registered office address, although LLCs and domestic stock corporations must also provide a separate Connecticut mailing address for the agent, which may be a P.O. Box.
The registered office address and the agent’s business office must be in Connecticut. For individual agents, the Certificate of Organization and the Certificate of Incorporation require both a business address and a Connecticut residence address. For business-entity agents, a Connecticut business address must be provided. The agent must sign the formation document accepting the appointment, which constitutes an affirmation of consent under penalty of false statement.
| Requirement | Individual Agent | Business Entity Agent |
| Connecticut presence | Must be a CT resident | Must be authorized to transact business in CT |
| Physical address | CT business address + CT residence address | CT business address |
| P.O. Box | Not acceptable as the registered office | Not acceptable as the registered office |
| CT mailing address | Required for LLCs and domestic stock corporations | Required for LLCs and domestic stock corporations |
| Consent | Signature on formation filing | Signature by authorized representative |
Is a Registered Agent Required in Connecticut?
Yes — a registered agent is mandatory for every business entity that forms or registers with the Connecticut Secretary of the State. Conn. Gen. Stat. § 33-660 requires each domestic corporation to continuously maintain a registered agent. The Connecticut Uniform Limited Liability Company Act imposes the same obligation on every LLC and every registered foreign LLC through Conn. Gen. Stat. § 34-243n, which states that “each limited liability company and each registered foreign limited liability company shall designate and maintain a registered agent in this state.” Limited partnerships, limited liability partnerships, and statutory trusts face comparable requirements under their respective chapters of the Connecticut General Statutes.
Foreign corporations seeking to transact business in Connecticut must also designate a registered agent on their Application for Certificate of Authority. Foreign LLCs register through the Foreign Registration Statement, which likewise requires agent appointment. A business that fails to maintain a registered agent risks administrative dissolution or revocation of its authority to transact business in the state.
Why Do I Need a Registered Agent in Connecticut?
A registered agent ensures that the business receives lawsuits, government notices, and compliance reminders through a reliable, designated contact point. Without a registered agent, a business has no guaranteed way to learn about pending litigation or approaching filing deadlines. A missed summons can lead to a default judgment, and a missed annual report notice can trigger administrative dissolution.
Beyond legal necessity, the registered agent protects business continuity. The agent provides a consistent address for state records even if the business relocates its offices. For sole proprietors and home-based businesses, appointing a separate agent also keeps a personal home address off the public record. An agent who is available during regular business hours ensures that time-sensitive documents are accepted on the first attempt rather than returned undeliverable.
Note: The Secretary of the State sends annual report reminders by email to the address on file. A registered agent who promptly forwards compliance notices helps the entity avoid the penalties and disruptions that follow a missed deadline.
Who Can Be a Registered Agent in Connecticut?
Connecticut law establishes distinct eligibility categories depending on the entity type. For domestic LLCs, Conn. Gen. Stat. § 34-243n permits the following to serve as registered agent:
- Natural person — must be a resident of Connecticut.
- Domestic corporation — formed under Connecticut law.
- Foreign corporation — holding a certificate of authority to transact business in Connecticut.
- Domestic LLC — organized under Connecticut law.
- Registered foreign LLC — registered to transact business in Connecticut.
- Domestic or foreign registered limited liability partnership — organized under Connecticut law or holding a certificate of authority.
- Domestic or foreign statutory trust — organized under Connecticut law or holding a certificate of registration.
For corporations, Conn. Gen. Stat. § 33-660 provides a similar list. Foreign corporations may additionally designate the Secretary of the State as their registered agent, an option available on the Application for Certificate of Authority.
An entity may not appoint itself as its own registered agent. The formation and registration forms state this explicitly: “The entity may not appoint itself as its registered agent.”
Can I Be My Own Registered Agent in Connecticut?
Yes — an individual who is a Connecticut resident may serve as the registered agent for his or her own business entity. An owner, member, manager, officer, or director who lives in Connecticut satisfies the statutory eligibility requirement for an individual agent. The formation filing requires the individual’s business address, Connecticut residence address, and Connecticut mailing address, along with a signature accepting the appointment.
Self-appointment, however, carries practical trade-offs. The individual’s Connecticut residence address becomes part of the public filing record, accessible to anyone who searches the state’s business database. The agent must also be available at the registered office during normal business hours to accept service of process in person. If the individual is frequently traveling, working remotely out of state, or simply unavailable during business hours, a process server may be unable to complete delivery, which can cause the entity to miss critical legal deadlines. For businesses with a single owner who works from home, the privacy and availability concerns often outweigh the cost savings of self-appointment.
Benefits of a Professional Connecticut Registered Agent Service
A professional registered agent service provides a dedicated Connecticut street address, business-hour availability, and document-handling infrastructure without requiring the business owner to be physically present. This arrangement addresses the main drawbacks of self-appointment: it separates the owner’s personal address from public filings, ensures consistent availability for service of process, and provides a stable address that does not change when the business relocates.
Professional services typically offer same-day electronic notification when documents arrive, secure online document storage, and compliance reminders for annual report deadlines. For businesses registered in multiple states, a professional agent can serve as the single point of contact across all jurisdictions, simplifying compliance management. The agent’s Connecticut address satisfies the registered office requirement, and the service handles the forwarding of legal papers to the entity’s officers or managers regardless of their physical location.
Hiring a Connecticut Registered Agent Before or After Formation?
A registered agent must be designated at the time of formation or registration — there is no grace period. The Certificate of Organization for a domestic LLC, the Certificate of Incorporation for a domestic corporation, and the Application for Certificate of Authority for a foreign corporation all include a required section for appointing the registered agent. The Secretary of the State will not accept a formation filing that omits the agent designation.
As a practical matter, the agent should be selected before the formation documents are prepared. The agent’s name, Connecticut address, and acceptance signature must appear on the filing itself. After formation, the entity may change its registered agent at any time by filing the appropriate change-of-agent form with the Secretary of the State. The initial appointment at formation is the only appointment that does not require a separate filing.
How to Appoint a Registered Agent in Connecticut
Appointing a registered agent in Connecticut is done by including the agent’s information in the entity’s initial formation or registration filing and having the agent sign the document. The following procedure applies to most entity types:
- Select a qualified registered agent — either a Connecticut-resident individual or an eligible business entity authorized to transact business in the state.
- Obtain the agent’s consent to serve, which is formalized through the agent’s signature on the formation document.
- Complete the applicable formation or registration form with the agent’s full legal name, Connecticut business address (no P.O. Box), Connecticut residence address (for individuals), and Connecticut mailing address (for LLCs and domestic stock corporations).
- Have the agent sign the form in the designated acceptance field.
- Submit the completed form to the Secretary of the State, Business Services Division, either online through Business.CT.gov or by mail to P.O. Box 150470, Hartford, CT 06115-0470 (or by delivery to 165 Capitol Avenue, Suite 1000, Hartford, CT 06106).
- Pay the applicable filing fee.
The table below shows formation filing fees for the most common entity types:
| Entity Type | Form | Filing Fee |
| Domestic LLC | Certificate of Organization | $120 |
| Domestic stock corporation | Certificate of Incorporation | $250 (includes franchise tax for up to 20,000 shares) |
| Domestic nonstock corporation | Certificate of Incorporation | $50 |
| Foreign stock corporation | Application for Certificate of Authority | $385 (includes $285 license fee) |
| Foreign nonstock corporation | Application for Certificate of Authority | $40 |
| Foreign LLC | Foreign Registration Statement | $120 |
Expedited processing is available for an additional $50 per transaction, as listed in the Fee Schedule.
How to Choose a Connecticut Registered Agent
Choosing a registered agent involves evaluating eligibility, reliability, and the practical implications of the appointment. The agent must meet the statutory qualification — either a Connecticut resident individual or a business entity authorized in the state. Beyond that threshold, several factors distinguish a good choice from a problematic one.
A reliable agent maintains a staffed physical address in Connecticut during regular business hours and has a system for promptly forwarding documents. The agent’s address will appear on the public record, so privacy-conscious owners should consider whether they want their personal address displayed in the Business Records Search database. Continuity matters as well — if the agent moves out of state, dissolves, or becomes unreachable, the entity must file a change of agent immediately or risk losing good standing. For businesses operating in multiple states, selecting an agent or service that can provide coverage across jurisdictions simplifies compliance management.
Consequences of No Registered Agent in Connecticut
Failing to maintain a registered agent in Connecticut exposes the business to administrative dissolution and loss of its authority to transact business. Under Conn. Gen. Stat. § 33-890, the Secretary of the State may administratively dissolve a corporation that fails to maintain a registered agent. For LLCs, Conn. Gen. Stat. § 34-267g provides for dissolution by forfeiture when an LLC fails to file its required annual report for more than one year, which can be triggered or compounded by the absence of a functioning agent.
The Secretary of the State’s guidance on administrative dissolution explains that an entity that has been administratively dissolved receives the status “forfeited.” Once forfeited, the business name becomes available for other entities to claim. The Secretary mails individual notices of dissolution to the principal business addresses on record and publishes notice on its website for at least sixty days.
Reinstatement after dissolution requires filing the overdue annual reports and paying reinstatement fees. For a domestic LLC, the reinstatement fee is $120; for a domestic stock corporation, it is $300 (which includes the required annual report). During the period of forfeiture, the entity cannot obtain a Certificate of Legal Existence (good standing), which may prevent it from entering into contracts, obtaining financing, or maintaining professional licenses.
Note: Administrative dissolution does not extinguish the entity’s debts or liabilities, but it severely limits the entity’s ability to conduct business and defend lawsuits.
Is Connecticut Registered Agent Information Public Record?
Yes — the registered agent’s name and address are part of the public record maintained by the Connecticut Secretary of the State. When an entity files its formation document, registration application, or change-of-agent form, the agent information is recorded in the state’s business registry and is accessible to anyone through the state’s online search tool. This means the agent’s full legal name, business address, residence address (if an individual), and mailing address are all publicly visible.
For business owners who serve as their own registered agent, this public-record exposure means their personal home address may appear in the search results. Appointing a professional agent or a separate business entity as an agent is one way to keep personal address information out of the public database while still satisfying the statutory requirement.
How to Search for a Connecticut Registered Agent
The Connecticut Secretary of the State provides a free online Business Records Search tool that displays the registered agent information for any entity on file. The search covers all domestic and foreign entities registered with the office.
- Navigate to the Business Records Search tool at Business.CT.gov.
- Enter the business name, business ALEI number, or filing number in the search field.
- Select the entity from the search results.
- Review the entity’s detail page, which displays the registered agent’s name, address, and other information currently on file.
The search tool replaced the former CONCORD system. Registered agent information cannot be changed on the annual report; a separate change-of-agent filing is required.
How to Become a Connecticut Registered Agent
Connecticut does not require a separate license or registration to serve as a registered agent. Any individual who is a resident of Connecticut or any eligible business entity authorized to transact business in the state may serve as a registered agent by accepting appointment on an entity’s formation or change-of-agent filing. The appointment becomes effective when the Secretary of the State accepts the filing.
To become a registered agent, the individual or business entity must provide a Connecticut street address that will serve as the registered office, consent to the appointment by signing the applicable form, and be available at that address during normal business hours to accept service of process. A professional commercial registered agent that represents multiple entities simply repeats this process for each client, accepting appointments for each entity’s filing individually. There is no cap on the number of entities for which a single agent may serve, and there is no annual registration or renewal fee for agents themselves — only the filing fees paid by the entities they represent.
Frequently Asked Questions:
Can a limited liability company serve as its own registered agent in Connecticut?
No. Connecticut law expressly prohibits an LLC from appointing itself as its own registered agent. The Certificate of Organization instructions state: “The Limited Liability Company may not be its own agent.” The LLC must appoint either a Connecticut-resident individual or a separate eligible business entity. A member or manager of the LLC who personally resides in Connecticut may, however, serve as the agent in an individual capacity.
Can the same individual or organization serve as registered agent for multiple Connecticut entities?
Yes. Connecticut law places no limit on the number of entities a single agent may represent. A Connecticut-resident individual or an eligible business entity may accept appointment as registered agent for as many domestic and foreign entities as it chooses. Professional registered agent services commonly represent hundreds or thousands of entities at a single Connecticut office address.
What happens if my registered agent resigns in Connecticut?
A registered agent may resign by signing and delivering a notice of resignation to the Secretary of the State. Under Conn. Gen. Stat. § 33-662, the resignation becomes effective thirty-one days after the Secretary receives it, unless a later date is specified. The Secretary mails notice of the resignation to the entity at its principal office address. The entity must appoint a replacement agent before the resignation takes effect; otherwise, it may lose good standing and face the consequences described under administrative dissolution. The resignation filing fee is $50 for most entity types.
Can I use a virtual office or P.O. Box as my registered office address in Connecticut?
No — a P.O. Box alone is not acceptable as the registered office address. Connecticut formation and change-of-agent forms require a full street address for the registered office. A virtual office arrangement may satisfy the requirement only if it provides a genuine physical street address in Connecticut where a person is present during business hours to accept service of process. A separate Connecticut mailing address, which may be a P.O. Box, is additionally required for LLCs and domestic stock corporations per the BUS-009 Change of Agent form.
What if my registered agent moves out of Connecticut?
If a registered agent is an individual who relocates out of state, that person no longer satisfies the Connecticut residency requirement and cannot continue to serve. The entity must file a change of agent promptly to appoint a new qualified agent. For domestic entities other than limited partnerships, this is done using the BUS-009 form at a fee of $50 (or $20 for nonstock corporations). Failure to appoint a replacement leaves the entity without a registered agent, which can trigger compliance problems and ultimately administrative dissolution.
Is a registered agent liable for the debts or legal obligations of the business it represents in Connecticut?
No. The registered agent’s statutory duty is limited to accepting service of process, notices, and demands and forwarding them to the entity. The agent does not assume any financial liability for the entity’s debts, contractual obligations, or legal judgments. The agent’s liability, if any, is limited to its own conduct — such as a failure to forward a properly served document. The entity and its owners, not the registered agent, remain responsible for the entity’s obligations.
How do I change my registered agent in Connecticut?
Domestic entities (except limited partnerships) change their registered agent by filing the BUS-009 Change of Agent form. Foreign entities (except limited partnerships) use the BUS-010 Change of Agent form. Both forms require the new agent’s name, Connecticut address, and acceptance signature. The filing fee is $50 for most entity types and $20 for nonstock (nonprofit) corporations. Filings may be submitted online through Business.CT.gov or by mail. To change only the agent’s address without changing the agent, file the BUS-003 Change of Agent’s Address form instead.
Does Connecticut require annual renewal of registered agent designation?
No. Connecticut does not require a separate annual renewal of the registered agent designation. However, the entity must keep its agent information current. The registered agent’s name and address cannot be updated through the annual report — a separate change-of-agent filing is required for any changes. Annual reports themselves are mandatory: LLCs file between January 1 and March 31 each year at a fee of $80, while domestic stock corporations file by the last day of their anniversary month at a fee of $150. Foreign stock corporations pay $435, and foreign nonstock corporations pay $50 for their annual reports. An entity that fails to file its annual report for more than one year may be administratively dissolved.
