Connecticut Registered Agent Service
Yes. Every Connecticut LLC, corporation, LP and LLP must designate and maintain a registered agent with a place of business in Connecticut. The state’s own Change of Agent form refuses a PO box: an individual agent gives a Connecticut business address and a Connecticut residence address, both street addresses.

Connecticut registered agent requirements
The rule
Governing statute: Conn. Gen. Stat. § 34-243n (LLC registered agent), § 34-243o (change of agent), § 34-247k (LLC annual report); § 33-660, § 33-661 and § 33-953 for corporations
The registered agent must have a place of business in Connecticut, and the written appointment must state the street and number. An individual agent must be a Connecticut resident; corporations, LLCs, LLPs and statutory trusts formed or authorized here may also serve. The Secretary of the State’s Change of Agent form takes no PO box.
Connecticut does not set statutory office hours. Service is made by leaving a true and attested copy with the agent, or — where the agent is an individual — at that agent’s usual place of abode in Connecticut, so the address has to be a real one you actually occupy.
If you have no agent
If the Secretary of the State learns you have no registered agent, or the agent cannot be found with reasonable diligence at the address on file, the office notifies you by email and administratively dissolves the entity unless you file an appointment of registered agent within three months.

How to appoint or change your registered agent in Connecticut
5 steps
to switch your registered agent in Connecticut.
Step 1: Pick an agent who qualifies — a Connecticut resident individual, or a Connecticut or authorized foreign corporation, LLC, LLP or statutory trust — with a place of business in the state
Agent consent
Step 2: Get the new agent’s written consent: filing the change is itself an affirmation to the state that the agent has consented to serve
Submit
Step 3: File the change online through your Business.CT.gov account, or complete the Change of Agent form (BUS-009 domestic, BUS-010 foreign)
Connecticut formChange of Agent (Form BUS-009 domestic; Form BUS-010 foreign) — or the equivalent online filing at Business.CT.govStep 4: Give street addresses only — the form rejects a PO box for both the business address and an individual agent’s Connecticut residence address
Records
Step 5: Keep the confirmation; you can also update agent details when you file the annual report

We handle the whole swapCan you be your own registered agent in Connecticut?
Yes. A Connecticut resident individual can serve as the entity’s registered agent, and so can a Connecticut entity you control. The form asks an individual agent for both a business address and a Connecticut residence address, neither of which can be a PO box — so your home address usually ends up on the public record. And because service can be left at your usual place of abode, a papered-over address means a default judgment you never saw coming. The full guide: Can you be your own registered agent?
Should you be your own registered agent?
Three honest questions about Connecticut. If you don’t need us, we’ll say so.
- Address privacyNow
- Reaching you with legal papers
- Other states
Is it fine if your home or office address goes on the public record?
As your own registered agent, the street address you list is the one that appears on Connecticut's public record.
Should you even hire a registered agent?
If you live in Connecticut, keep regular hours at a fixed address, and run one entity, you may not need us, and we will tell you so. A service earns its keep when you value privacy, travel, run more than one entity, or operate across state lines.

Connecticut registered agent FAQ
Do I need a registered agent in Connecticut?
Yes. Conn. Gen. Stat. § 34-243n requires every LLC and registered foreign LLC to designate and maintain a registered agent with a place of business in Connecticut, and § 33-660 imposes the same duty on corporations. An individual agent must be a Connecticut resident. The Secretary of the State’s Change of Agent form will not accept a PO box for the address.
Can I be my own registered agent in Connecticut?
Yes, if you are a Connecticut resident, and a Connecticut entity you control can serve as well. The catch is exposure: the state’s form asks an individual agent for a business address and a Connecticut residence address, both street addresses, so your home usually goes on the public record. Service can be left at your usual place of abode.
What happens if my Connecticut LLC has no registered agent?
The Secretary of the State can act. When the office learns you have no agent, or the agent cannot be found with reasonable diligence at the address on file, it sends notice by email and administratively dissolves the entity unless you file an appointment of registered agent within three months. Lawsuits meanwhile proceed without reaching you.
How do I change my registered agent in Connecticut?
File the change online through your Business.CT.gov account or submit the Change of Agent form — BUS-009 for a domestic entity, BUS-010 for a foreign one. Filing it is your affirmation that the new agent consented, so secure that first. Use street addresses only, since the form refuses a PO box. You can also update agent details on the annual report.
How much does a Connecticut registered agent cost?
Pricing is custom to your portfolio of entities and states, and most quotes are same-day. Call 212-202-5750 or start a filing and we’ll price exactly what you need. State filing fees are set by the state and confirmed with you before anything is filed, so nothing is submitted until you have seen the full cost.
