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.

Deadline rules from the Connecticut Secretary of the State, Business Services Division · reviewed September 2026. We confirm every date when you file.
What does Connecticut require of your registered agent?
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.
New to the role? How legal papers reach your business — the role, explained in plain English.
Other states call the same role a registered agent, resident agent, statutory agent or agent for service of process. In Connecticut the law says registered agent. Which term each state uses.

How do you appoint or change your registered agent in Connecticut?
Procedure scope: Registered agent changes for a Connecticut domestic LLC using the online change service or the domestic Change of Agent form.
5 steps
to switch your registered agent in Connecticut.
Step 1: Confirm the exact LLC name in the Secretary of the State's records and select a qualified Connecticut resident individual or an eligible business agent on record with the office. The LLC cannot appoint itself.
Step 2: Open the online Change your business agent service, or complete the domestic Change of Agent form for an entity formed in Connecticut.
Connecticut formChange of Agent — Domestic, BUS-09 (also listed as BUS-009)Step 3: For an individual, provide the residence street address and business street address, or use the no-business-address box when applicable. For a business agent, provide its exact registered name and Connecticut business street address.
Step 4: Provide the agent's required Connecticut mailing address for an LLC; a PO box may be used for that mailing address, not for a required street address.
Agent consent
Step 5: On paper, obtain the agent's acceptance signature and the authorized company official's execution signature, title and date. Submit to Business Services using the current form's delivery instructions and retain the confirmation.

Can 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.

Questions about registered agent service in Connecticut
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?
Registered agent changes for a Connecticut domestic LLC using the online change service or the domestic Change of Agent form. Connecticut offers an online agent change and a domestic paper form. On the paper route, the appointed agent signs acceptance and an authorized company official separately signs the filing. The domestic form covers domestic entities except limited partnerships. Foreign LLCs use the foreign Change of Agent route and identify their home jurisdiction and Connecticut name. The inspected foreign paper form is revised July 2017 and offers the Secretary of the State as an alternative agent; confirm the current foreign route and delivery details rather than copying its older delivery address.
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.
