How to change your registered agent in Connecticut
-
Choose your new registered agent first.
Do not file the change form until you have a new agent lined up. The new agent has to consent to the appointment, and most states will not process the change without that consent in hand. If you let coverage lapse, the Connecticut SOS can administratively dissolve your LLC.
-
Get the Change of Agent (Form ACD-1-1.0). Download the form ↗
You can file this online through the Connecticut Secretary of State portal. The form requires your LLC name, the new agent name and address, and a signature. The new agent must consent to the appointment.
-
Pay the $50 filing fee.
Pay by credit card during the online filing. A small processing surcharge usually applies. Mail filings accept check or money order made out to the Connecticut Secretary of State.
-
Notify your old agent.
Once the change is processed, your old agent's responsibility ends. If you are paying them an annual fee, cancel that subscription so it does not auto-renew. Most services prorate or refund the unused portion.
-
Verify the change in state records.
Search your LLC name on the Connecticut SOS business search and confirm the new registered agent is listed. Processing typically takes 3-5 business days standard; 24-hour expedite available for $50 extra, so check back after that window.
Important to know about Connecticut
- Connecticut retired its old CONCORD filing system in 2021. All online filings now go through business.ct.gov One Stop.
- There are separate Change of Agent forms for domestic (CT-formed) and foreign entities. Use the right one for your LLC.
- You can change the agent through a Certificate of Amendment instead, but at $120 it is more expensive than the $50 standalone Change of Agent.
