Updated 2026-04-30 · Verified against Connecticut Secretary of the State
Under Conn. Gen. Stat. §34-243n, every LLC and corporation organized or registered to do business in Connecticut must designate a registered agent. The agent must have a physical street address in Connecticut — P.O. boxes and commercial mailbox addresses without a registered street component are not acceptable — and must be available during normal business hours to accept service of process. The agent’s name and street address are filed with the Connecticut Secretary of the State and become part of the public business record.
Beyond appointing an agent, Connecticut LLCs file Articles of Organization with the Connecticut Secretary of the State at a cost of $120, with ongoing maintenance handled through an annual report of $80 due annually by March 31. Connecticut raised its LLC annual report fee from $20 to $80 in 2020 and the fee remains among the higher per-year costs in New England.
