How long does it take to change a registered agent in Connecticut?

In Connecticut, changing your registered agent typically takes 5 to 10 business days when filing by mail with the Connecticut Secretary of the State, or 1 to 3 business days for online submissions through the Connecticut Business Services portal. If you need faster service, expedited processing is available for an additional fee, offering same-day or next-day turnaround. This timeline matters because your LLC remains legally responsible for any missed notices or legal documents during the transition period. Connecticut law requires that a registered agent be continuously designated, so delays could expose your business to compliance issues if regulatory notices arrive undelivered. To proceed, file a Statement of Change of Registered Agent (Form LLC-2.2) either online via the Secretary of the State's website or by mail to P.O. Box 150470, Hartford, CT 06115 to 0470. Submit your filing immediately to minimize the window where service gaps could occur.

What does it cost to change a registered agent in Connecticut?

Connecticut charges a $50 filing fee to change your registered agent through the Certificate of Change of Registered Agent, submitted to the Connecticut Secretary of the State's Business Services Division. If you need the change processed within 24 hours, expedited service costs an additional $50, making the total $100. Beyond state fees, you may incur notarization costs ($10 to $25 depending on your notary) if your registered agent change requires a notarized signature. For most LLCs, the baseline $50 fee is sufficient unless you've an urgent business need. This relatively low cost makes it practical to switch agents if your current one becomes unresponsive or unreliable, a critical decision since your registered agent receives legal documents and tax notices on your behalf. File Form LLC-2A through the Secretary of the State's online filing system or by mail to complete the change within 10 to 15 business days.

Can I be my own registered agent in Connecticut?

Yes, you can serve as your own registered agent in Connecticut if you maintain a Connecticut street address and are a resident of the state. However, this role requires your availability during standard business hours to receive legal documents and official correspondence from the Connecticut Secretary of the State's office and other parties. Your personal name and Connecticut street address will appear in the public business records maintained by the Connecticut Secretary of the State, making them accessible to anyone searching your LLC. This means service of process, tax notices, and compliance documents will arrive at your residence, creating potential delays if you're unavailable. The practical implication is significant: if you miss a critical deadline or don't promptly forward documents to your LLC's management, it could jeopardize your business's legal standing or cause you to miss important tax deadlines with the Connecticut Department of Revenue Services. To proceed, file Form LLC-4.1 (Change of Registered Agent/Registered Office) with the Connecticut Secretary of the State, paying the $50 filing fee.

Will changing my registered agent affect my LLC's good standing?

No, changing your registered agent won't affect your Connecticut LLC's good standing status provided you file the change properly and maintain continuous registered agent coverage. The Connecticut Department of Consumer Protection (DEEP) recognizes registered agent changes as routine administrative updates that don't trigger compliance violations. However, failing to maintain an active registered agent at all times can result in automatic administrative dissolution under Connecticut General Statutes Section 34-119. This means you can't have a gap between your current agent's termination and your new agent's appointment. For LLC owners, this creates a practical requirement: file your registered agent change using Form LLCRA (Amendment to Certificate of Formation) before your existing agent's resignation takes effect. The filing fee is $75, and DEEP typically processes submissions within 5 to 7 business days. Without an active agent on file, you risk losing your LLC's legal status and facing reinstatement fees of up to $200. Submit your amendment to the Connecticut DEEP's Business Services Division immediately when planning an agent transition.

Can I file the registered agent change online or do I need to mail it?

Connecticut allows you to file your registered agent change online through the Connecticut Secretary of the State's Business Services portal at https://portal.ct.gov/sots, which is the faster option. You can alternatively mail Form LLC-4.2 (Certificate of Change) to the Connecticut Secretary of the State, Legislative Office Building, 300 Capitol Avenue, Hartford, CT 06106. Both methods require a $75 filing fee. Online filing typically processes within 1 to 2 business days, while mailed submissions take 5 to 7 business days. This matters because your new registered agent can't legally receive service of process until the change is officially recorded, delaying this leaves your LLC vulnerable to missed legal notices. To proceed, access the portal at https://portal.ct.gov/sots, select "File Online," upload Form LLC-4.2 with your new agent's information, and pay the fee by credit card for immediate confirmation.

Registered agent services for Connecticut LLCs, by renewal price

Affiliate disclosure: Northwest Registered Agent, Bizee, ZenBusiness and LegalZoom pay us a commission if you sign up through our link, at no extra cost to you. We list only the registered agent services we have an affiliate relationship with, so this is not a survey of the whole market.

This table is not scored. The four are listed cheapest annual renewal first, and the rows below it say which one fits which situation. The scored ranking, and the formula behind it, is on the formation services review, which orders them on three-year cost, BBB rating and Trustpilot score.

Service	With formation, year 1	Annual renewal	BBB	Trustpilot	Privacy
Northwest Registered Agent	Included with $39 formation	$125/yr	A	4.1/5 (297)	Says it does not sell your information; runs its own servers
Bizee	Free year one	$149/yr	C (unaccredited)	4.8/5 (26,100+)	No data-sharing commitment

LegalZoom	Not included, $249 extra	$249/yr	A+	4.6/5 (32,900+)	Partial

Note: Bizee holds a C rating from the BBB and is not accredited. BBB's profile carries a live alert describing a pattern of complaints about unexpected charges, difficulty canceling and filing delays, and Bizee has posted a response to it. We flag this so you can make an informed choice.

This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each state publishes about filing deadlines, fees, and the consequences of missing them, with the sources this page cites. It cannot tell you what your own company owes: the date turns on when and where you formed, states change these rules between our reviews, and in several states an entity-level tax falls due in a year when no report does. Confirm your own dates with the filing office named on this page before you rely on one here, because the penalty for missing a deadline can be administrative dissolution of the company.
