A Connecticut registered agent is your business's legal front door. State law requires every LLC, corporation, limited partnership, and nonprofit registered in Connecticut to name one person or company with a physical Connecticut address to accept government notices and legal papers on the entity's behalf.
That agent receives service of process, including lawsuits, subpoenas, summons, and court documents, plus official correspondence from the Secretary of the State. The obligation sits in Connecticut General Statutes Title 33, Chapter 601, Section 33-660(a) for domestic corporations, and in Title 34, Chapter 613a, Section 34-243n(a) for LLCs. The LLC statute reads: "Each limited liability company and each registered foreign limited liability company shall designate and maintain a registered agent in this state."
Annual report reminders go to the business email address on file with the Secretary of the State, not to your agent. Keep that address current alongside the agent appointment, because dissolution notices arrive there too.
Requirements of Connecticut registered agents
Connecticut spells out who can serve as a registered agent and how the appointment must be documented, and the Secretary of the State's forms enforce those rules field by field.
Requirement | What it means for you |
|---|---|
Physical address | Your agent needs a real Connecticut street address; the official Certificate of Organization form marks those fields as required and rejects P.O. Boxes, which belong only in the separate mailing address field. |
Eligibility | You can name a Connecticut resident, a domestic corporation, a foreign corporation holding a Connecticut certificate of authority, a domestic or registered foreign LLC or LLP, or a statutory trust. Since January 1, 2025, Public Act 24-111, codified at Section 3-99g, has required an individual agent to be an adult (18 or older) and a Connecticut resident during the entire time they are named. |
Availability | Someone must reliably be at that address, because an agent who "cannot be found" at the address on record is a stated ground for administrative dissolution. |
Consent to serve | For corporations, Chapter 601 requires the appointment to be in writing and signed by the agent; for LLCs, a change of agent certificate must be signed by the new agent. |
Continuous appointment | Corporations must "continuously maintain" an agent and LLCs must "designate and maintain" one, and a lapse starts a three-month clock toward dissolution. |
Public record | The agent's name is included in Connecticut's business registration data, and the agent's street address appears on your filed documents. |
Being your own registered agent is legal but rarely practical. You would need to be reachable at a Connecticut address whenever a process server arrives, and your name would sit in the state's records as the contact for lawsuits.
Why do you need a Connecticut registered agent?
Connecticut requires many domestic and foreign registered entities to keep an agent on file, including LLCs, corporations, foreign LLPs, and registered LLPs that do not have a principal office in the state. Under Section 33-890(c), a corporation that fails to maintain one receives an email notice from the Secretary of the State and has three months to file a new appointment before the state files a certificate of administrative dissolution.
LLCs face the parallel "dissolution by forfeiture" under Section 34-267g(c), with the same three-month cure period and the same email notice.
Failing to maintain proper coverage exposes you to:
Administrative dissolution or dissolution by forfeiture, after which the entity may carry on only the business needed to wind up its affairs
Default judgments when a lawsuit is served and nobody forwards it
Missed state correspondence and legal deadlines
Loss of good standing; a dissolved entity may still need to check with the Connecticut Secretary of the State to determine whether a Certificate of Legal Existence is available and what status or dissolution information it will show
Reinstatement is available, but the process and cost differ by entity type. LLCs dissolved by forfeiture may reinstate at any time, with no statutory outside deadline, by filing a combined certificate of reinstatement and annual report for $120. Corporations administratively dissolved may apply for reinstatement after the effective date of dissolution with no outer time limit either, but the process runs closer to $150 plus the current annual report fee ($150 for stock corporations, $80 for nonstock) and typically requires tax clearance from the Department of Revenue Services.
A professional agent also keeps a principal's home address out of the agent field and puts someone at the address no matter your travel schedule. Same-day scanning with real-time notifications is worth looking for when you compare commercial agents. Understanding what a registered agent does day to day makes it easier to decide whether a commercial registered agent service is worth the fee for your entity.
How to appoint or change your Connecticut registered agent
Designating an agent in Connecticut requires attention to detail. A missing agent signature on a corporation filing, a P.O. Box in the street address field, or the wrong document name will send you back to the portal.
Initial appointment during formation
List the agent in your formation document. LLCs file a Certificate of Organization, renamed from Articles of Organization by Public Act 16-97 effective July 1, 2017. Corporations file a Certificate of Incorporation.
Document consent. A corporation's appointment must be in writing and signed by the agent. For an LLC, the designation itself affirms that the agent consented, and the Certificate of Organization must list the registered agent appointed in compliance with Connecticut's registered-agent statute.
Verify the address. Use a physical Connecticut street address for the agent; Connecticut law does not treat a P.O. Box as a registered-agent address or usual place of business.
File and pay. Submit the filing to the Secretary of the State. The LLC filing fee is $120 including the agent appointment. Stock corporations remit $250 at formation.
Changing your existing agent
Select a qualified replacement that meets the eligibility rules above and obtain its consent. Corporations need the new agent's written consent on or attached to the statement of change; LLC change of agent certificates must be signed by the new agent.
Complete the Change of Agent filing. Connecticut's statutes and online portal distinguish domestic entities from foreign entities and vary by entity type, so confirm you're on the correct version of the filing for your entity before you submit. Include your entity name, the outgoing agent, and the new agent's Connecticut street address.
Pay the fee. The Change of Agent fee is $50 for LLCs and stock corporations and $20 for nonstock corporations. The Secretary of State does not publish a guaranteed turnaround for agent changes, though most online filings are accepted automatically; Connecticut law allows the Secretary to require online submission for Business Services filings and authorizes a $50 expedited fee for eligible online transactions.
Update records and notify. Amend your internal records and tell the outgoing agent so future deliveries are not misdirected. Agent information can also be updated while filing your annual report.
If your current agent resigns, you have 31 days of coverage. A corporation's agent files a statement of resignation, the Secretary of the State mails or delivers a copy to your principal office, and the appointment ends on the 31st day after filing under Section 33-662(c).
Under Section 34-243p(a)-(c), an LLC's registered agent may file a certificate of resignation, must immediately furnish the company notice in a record of the date the certificate was filed, and the resignation takes effect on the earlier of the 31st day after filing or the date you designate a new agent; agents can submit resignations by delivering the appropriate resignation filing to the Secretary of the State.

FAQs about Connecticut registered agents
These are the questions Connecticut business owners and compliance teams ask most often about registered agents.
Can you serve as your own registered agent in Connecticut?
Yes, if you are a Connecticut resident who is 18 or older when named and you have a physical street address in the state (P.O. Boxes are not accepted for the agent address). The age and residency rule became statutory under Public Act 24-111 on January 1, 2025, codified at Section 3-99g. Your name is included in the registered agent filing submitted to the state, and a missed delivery can lead to a default judgment.
What happens if your registered agent resigns?
The agent files a resignation with the Secretary of the State. For a corporation, the state mails or delivers a copy to you; for an LLC, the agent must notify you directly. The appointment terminates 31 days after filing, or sooner for an LLC if you name a replacement first. Once the state determines an entity has no registered or statutory agent, it may send notice (by email for corporations and nonstock corporations, or by email or registered/certified mail under the LLC provisions) and generally gives three months before administrative dissolution or dissolution by forfeiture.
Does the role differ for LLCs, corporations, partnerships, or nonprofits?
The duties are identical across entity types: accept service of process and state correspondence, then forward everything promptly. The governing statutes differ by entity type, and so do the fees; nonstock corporations pay $20 rather than $50 to change agents. Whatever the entity type, a dissolved entity keeps its legal existence but can act only to wind up its affairs.
What exactly must a registered agent do?
Your agent must be available at its Connecticut street address to receive lawsuits and official state correspondence, and it must forward every document promptly to your business. Under Section 33-890(c), an agent who cannot be found at the address on record puts the entity on the path to dissolution.
How can you tell if your agent is doing a good job?
You should receive timestamped scans or overnight deliveries the same day documents arrive, plus timely email or SMS alerts. Warning signs include unexplained mail delays, bounced service attempts, or an outdated address in the Secretary of the State's business records. Since annual report reminders go to your business email rather than your agent, a good agent also tracks your annual report deadline independently rather than waiting on the state's notice.
