The quick read on Connecticut registered agents

Every Connecticut LLC is legally required to maintain a registered agent with a physical street address in the state. The role is to receive service of process (lawsuit papers), state tax notices, and other official government mail on the LLC's behalf. You can serve as your own agent if you live in Connecticut and meet the requirements, or hire a commercial service for typically $99 to $299 per year.

Connecticut-specific rules matter. The statute is Conn. Gen. Stat. § 34-243n and § 34-243o. The registered agent's address goes on the public state record, so most owners who want privacy use a paid service to keep their home address off the record. Owners who live in the state and don't mind the public listing often save $100 to $250 per year by serving as their own agent.

Who can serve as a registered agent in Connecticut

Connecticut allows an individual Connecticut resident at least 18 years old with a Connecticut business address, a domestic Connecticut entity, or a foreign entity authorized to transact business in Connecticut, to serve as registered agent. The agent must sign an acceptance as part of the filing (submitted electronically through business.ct.gov). PO boxes are not accepted as the business address.

Connecticut does not operate a commercial registered agent registry, so any qualifying person or entity can serve without pre-registration. The LLC's own member or manager can serve if they meet the residency rule. For the broader setup, see our Connecticut LLC formation guide.

What Connecticut requires of a registered agent

  1. Physical street address in Connecticut

    Not a PO box, not a mail-drop. The address becomes part of the public record visible on the Secretary of State's business entity search.

  2. Available during business hours

    Typically 9 AM to 5 PM, Monday through Friday. The agent has to be physically present (or have staff present) to accept service, not just reachable by phone or email.

  3. At least 18 years old and a resident or registered entity

    Individual agents must be 18+ and reside in Connecticut. Entity agents must be registered to transact business in Connecticut.

  4. Written consent on file

    Connecticut requires the registered agent to consent in writing to serve. Formation services handle this automatically when you sign up. For an individual agent, a simple signed consent letter suffices.

Choosing the right registered agent in Connecticut

If you live in Connecticut and run the LLC from a home or office address, self-serving saves $100 to $250 per year. The tradeoff is that your address goes on the public Secretary of State record. Connecticut's annual $80 report is also the primary compliance checkpoint, which self-serve agents need to track manually.

For non-Connecticut residents, a commercial service is required. Pricing runs $99 to $149 per year (Bizee $119, Northwest $125, ZenBusiness $99 first year). Connecticut's market for local boutique RAs is thinner than Wyoming or Delaware, so most filers use a national option. Northwest at $125 with price-lock is the usual middle-ground choice, particularly because it handles annual report reminders, which matters more in Connecticut than in Colorado given the $80 report fee and 90-day dissolution trigger.

If you let your Connecticut registered agent lapse

Under Conn. Gen. Stat. § 34-267c, Connecticut can administratively dissolve an LLC that fails to maintain a registered agent or file required annual reports. The $80 annual report is the primary enforcement trigger; missing it for roughly 90 days leads to dissolution. Reinstatement requires a $120 reinstatement fee plus any unpaid annual reports. A three-year lapse can easily run $360 or more to fully remedy before the LLC regains good standing.

Frequently Asked Questions

  • Who can serve as a registered agent for a Connecticut LLC?

    An individual Connecticut resident at least 18 years old with a Connecticut business address, a domestic Connecticut entity, or a foreign entity authorized to transact business in Connecticut. PO boxes are not accepted. The agent must sign an acceptance as part of the filing. The LLC's member or manager can serve if they meet the residency rule.

  • How much does a Connecticut registered agent service cost?

    National services price between $99 and $149 per year (Bizee $119, Northwest $125, ZenBusiness $99 first year). Connecticut has a thinner local boutique market than Wyoming or Delaware, so most filers use a national service. LegalZoom charges $249 without meaningfully better service.

  • Can I be my own registered agent in Connecticut?

    Yes, if you're a Connecticut resident at least 18 years old with a Connecticut business address and availability during business hours. Your address goes on the public Secretary of State record. You'll also need to track the $80 annual report deadline, since missing it triggers administrative dissolution after 90 days.

  • What does it cost to change my Connecticut registered agent?

    $50 for the Change of Agent filing, submitted online through business.ct.gov. Processing typically takes about 3 business days. The new agent's acceptance is captured electronically as part of the filing. Most commercial services handle the paperwork for free when you switch your RA to them.

  • What happens if my Connecticut LLC's registered agent resigns?

    You need to designate a replacement before the Secretary of State takes action under Conn. Gen. Stat. § 34-267c. If the LLC also falls behind on the $80 annual report for 90+ days, administrative dissolution follows. Reinstatement costs $120 plus any unpaid annual reports. A three-year lapse can easily total $360 or more.

  • Is the Connecticut annual report more important than the registered agent?

    Both are required, and Connecticut uses annual report compliance as the primary enforcement signal. Missing the $80 annual report for 90 days triggers administrative dissolution faster than a silent RA lapse in most cases. A commercial RA service that tracks and files the annual report (Northwest, Bizee Gold tier) can prevent the compound compliance failure that typically causes Connecticut LLC dissolutions.

  • Do I need a registered agent for a Connecticut LLC?

    Yes. Connecticut law requires every LLC to designate a registered agent with a physical street address in Connecticut and availability during business hours. There is no exception for inactive or small LLCs. If the LLC loses its registered agent and doesn't designate a replacement within the state's grace period, Connecticut begins administrative dissolution of the entity.

  • How much does a registered agent service cost in Connecticut?

    National services range from $99 per year (ZenBusiness) to $299 per year (Firstbase). The $190 average is close to the market median. Connecticut-based local registered agent services also operate in the state, typically pricing between $50 and $150 per year.

  • How do I change my registered agent in Connecticut?

    File Change of Agent and/or Agent's Address with Connecticut Secretary of the State, Business Services Division. The fee is $50. Online filing is accepted. Processing takes about 3 business days. Most formation services handle this paperwork for free when you sign up.

  • Is the registered agent fee tax deductible?

    Yes. Registered agent fees are an ordinary and necessary business expense deductible on the LLC's federal tax return (Schedule C, Form 1065, or 1120/1120-S depending on tax treatment). Connecticut state tax treatment follows federal on this deduction. Keep the invoices with your tax records.
