Change Your
Connecticut Registered Agent: Step-by-Step

When Connecticut LLCs change registered agents

Connecticut requires every LLC to maintain a registered agent on file with the Connecticut Secretary of the State, Business Services Division. The agent is the address where lawsuits and official Connecticut state mail are delivered. When you change the person or company in that role, the state has to be told within a short window — typically the same year of the change, and in many cases within 30 days.

The handful of common reasons we see founders change Connecticut registered agents:

• The current agent resigned. Commercial agents can resign with notice; if you do not name a replacement, Connecticut will eventually administratively dissolve the LLC.
• You moved out of Connecticut and were serving as your own agent. The agent must have a physical Connecticut address — a post office box or out-of-state forwarding address does not satisfy Connecticut law.
• Privacy. Your home address is currently on the public Connecticut Secretary of the State record. A commercial agent in Hartford replaces it with a business address.
• Cost. A previous service is renewing at $200–$300/year and you want to consolidate or downgrade.
• Service quality. The current agent is slow to forward service of process, missed an annual report reminder, or is hard to reach.

The five steps to change your Connecticut registered agent

1. I.

   Pick the new agent first

   Confirm the replacement before you remove the current one. The new agent must be a Connecticut resident over 18 with a physical Connecticut address, or a business entity authorized to transact business in Connecticut. If you are using a commercial service, sign up before you file the change so the address you list is real on day one.

2. II.

   Get the new agent's written consent

   Connecticut requires the incoming registered agent to consent to the appointment. Most online change forms include a consent line the new agent signs (or e-signs). Commercial registered agent services handle this automatically.

3. III.

   File the Statement of Change with the Connecticut Secretary of the State

   Connecticut's change-of-agent filing is usually called a Statement of Change of Registered Agent or a Change of Registered Agent and/or Office. Submit it through the Connecticut Secretary of the State portal at portal.ct.gov. You list the LLC's name and Connecticut file number, the prior agent and address, the new agent and address, and an effective date.

4. IV.

   Pay the state fee

   Connecticut typically charges between $10 and $50 to process the change. Online filings are usually paid by credit card on submission. Confirmation arrives by email within a few business days; many states accept the change instantly online.

5. V.

   Notify the outgoing agent

   If you are leaving a paid commercial agent, send written notice to cancel the renewal. Most services do not refund the unused portion of an annual fee — but they will stop billing in the next cycle. Save the cancellation confirmation with your LLC records.

Common Connecticut mistakes

• Removing the old agent before the new one is in place. Connecticut does not let your LLC sit without an agent on file. If the change form leaves the slot blank, the Connecticut Secretary of the State will reject the filing.
• Listing a P.O. box. Connecticut requires a physical street address for the registered office. Mail-forwarding addresses without a real person at the location do not satisfy service-of-process rules.
• Forgetting the principal office address. Many Connecticut change forms ask whether the principal office address has also changed. If you are moving the agent because you moved house, update both — separately or on the same form.
• Not telling the IRS or banks. Your registered agent address is not the same as the address on file at the IRS (Form 8822-B) or your business bank. If you used the old agent's address for either, update those separately.

How long the change takes effect

Online filings with the Connecticut Secretary of the State are typically processed within 1–5 business days, sometimes the same day. Mail-in filings take longer — plan on 2–4 weeks. Once accepted, the change is reflected in the public Connecticut business record and any service of process or state mail goes to the new address from that point forward.

If service of process arrives at the old agent during the gap between filing and acceptance, the old agent is still legally responsible for forwarding it. That is one reason to time the change with at least a brief overlap rather than terminating the prior agent the day before you file.

How we can help

If you formed your Connecticut LLC with us, our Hartford office is already on file as the registered agent for the first year — no change needed. After that, renewal is $119/year, opt-in. If you formed elsewhere and want to switch to us, we file the Connecticut change-of-agent form for you and serve as the agent of record from acceptance forward; the state filing fee is paid directly to Connecticut.

Either way, the change is straightforward — verify with the Connecticut Secretary of the State for the current fee and exact form name, then file. Our role is to make sure nothing falls through the gap.
