The steps
-
Step
1Find out what Connecticut asks of an agent
Every LLC must name a registered agent with an in-state street address.
Where this comes from: cga.ct.gov confirms it, as of October 2026
-
Step
2Confirm who may be the agent
A Connecticut resident, or a business entity formed in Connecticut or registered there. The agent signs to accept the appointment. See Conn. Gen. Stat. § 34-243n.
-
Step
3Check the registered office address rule
The address has to be a Connecticut street address that is not a P.O. box, plus a Connecticut mailing address, which can be a P.O. box.
A service gives you a Connecticut street address, which keeps your home address off the filing.
-
Step
4Settle who will be the agent
Qualified owners may act as their own agent. Otherwise our graded picks charge $99 to $149 per year.
-
Step
5Record the agent with the state
The Certificate of Organization asks for the agent's name and address, and the Connecticut Secretary of State also accepts change filings for LLCs that switch agents.
Where this comes from: business.ct.gov confirms it, as of October 2026
-
Step
6Look after it year by year
Connecticut sees your agent's details through the annual report ($80, every year, due on or before March 31), and the state's letters about it go to your registered agent.
Where this comes from: business.ct.gov confirms it, as of October 2026
