How to Change Your Registered Agent in Connecticut (2026)
To change your registered agent in Connecticut, file Form BUS-009. Send it to the Secretary of the State's Business Services Division. The fee is $50 for an LLC or corporation, or $20 for a nonstock corporation.
You can file online, by mail, or in person. A registered agent service can also handle the whole thing for you.
Connecticut uses the term "registered agent," so the name here matches what you may already know from other states. Your new agent has to sign the form first. The state won't process the change without that signature.

Who Can Be a Connecticut Registered Agent
Connecticut lets two kinds of agents serve your business: a person who lives in the state, or a business allowed to operate here [1]. A person must be at least 18. They must stay a Connecticut resident the whole time they hold the role.
The law's list of who can serve names people and outside businesses. It never names the company itself, so your LLC can't act as its own registered agent. That's part of why many owners hire a registered agent service instead.
The agent's address matters as much as who they are. Connecticut calls it a "usual place of business." That means a spot in the state open during normal hours, with someone there to take legal papers. A P.O. box does not count, government or commercial [2]. The same standard applies whether the agent is an individual working from a home office or a company staffing a commercial location, so check the address against this rule before you list it on Form BUS-009.
How to Change Your Connecticut Registered Agent
Line up your new agent first. Make sure they meet Connecticut's rules. Then file Form BUS-009 with their signature attached. The state will not process the change without that signed page.
The steps below cover Connecticut only. For the general process in every state, see our national guide on changing your registered agent. If you'd rather skip a standalone filing, Connecticut also lets you update your registered agent's information right in your annual report instead of filing Form BUS-009 separately [3].
1. Filing Online
Create an account on CT Business One Stop, or sign in if you already have one. Then start the Change of Agent transaction. This is the quickest of the three options.
Enter your new agent's name and address, and attach their signed acceptance. Pay the filing fee shown in Quick Facts to complete the transaction.
Expedited service adds $50, and it only works for online filings, not mail. Connecticut does not post a standard processing-time estimate for either speed, so leave some buffer either way.
2. Filing by Mail
Get Form BUS-009 from the Secretary of the State's website. Fill it out, then get your new agent to sign the acceptance section.
If your agent is a person, list their full legal name, their Connecticut address, and their signature. If it's a business instead, list the exact name on file with the state, its Connecticut address, and a signature from someone who can sign for it.
Print the finished form. Attach a check made out to "Secretary of the State" for the fee. Mail it all to:
Business Services Division
Connecticut Secretary of the State
P.O. Box 150470
Hartford, CT 06115-0470
Mailed filings can't use expedited service, since Connecticut only offers that option to online filers. Connecticut doesn't publish a standard processing window for mail either, so plan for some open-ended wait.
3. Filing in Person
You can also drop off Form BUS-009 in person, signed and ready. Bring your payment too, and take it to the Business Services Division's office in Hartford. Their address is:
Business Services Division
165 Capitol Avenue, Suite 1000
Hartford, CT 06106
4. Using a Registered Agent Service
If you'd rather skip the paperwork, a good provider will confirm your new agent's acceptance, file Form BUS-009 for you, and then take over as your agent going forward. You can find one through our registered agent service picks for Connecticut.
You'll pay their yearly fee on top of the state's filing fee. In return, they handle the form and the signature for you.
