Registered Agent Requirements in Connecticut: § 34-243n Explained

Connecticut law demands that every LLC, corporation, and limited partnership maintain a registered agent. This is not a suggestion or a best practice; for LLCs it is a statutory obligation codified at Conn. Gen. Stat. § 34-243n and enforced by the Secretary of the State. Here is a comprehensive breakdown of the role, the statute's exact requirements, and why professional service at $99/year represents the strongest value available.

What the Agent Receives

Your registered agent is the designated recipient for:

• Service of process — lawsuits, summons, complaints, subpoenas served against your entity
• Secretary of State correspondence — annual report reminders, compliance notices, filing confirmations
• Tax agency mail — Department of Revenue Services communications and other state tax notices
• Regulatory documents — licensing updates, administrative actions, government inquiries

These documents often carry deadlines. A missed lawsuit response can produce a default judgment. A missed compliance notice can lead to dissolution. The agent's reliability directly impacts your legal exposure.

What § 34-243n Actually Requires

The controlling statute for LLCs is Conn. Gen. Stat. § 34-243n. Its address rule is blunt: the agent "shall have a place of business in this state" (§ 34-243n(e)). The state's forms translate that into a required street address for the registered office (business or residence; a PO box does not qualify) plus a Connecticut mailing address, which may be a PO box.

Eligible agents fall into defined categories:

No appointment is effective until the named agent signs an acceptance. Individual agents disclose a residence address, and that address becomes part of the permanent public record.

The entity itself is off the list. The Secretary of the State's guidance frames the business-entity option as "any other business entity registered with our office," and the state's annual report instructions state that an LLC cannot serve as its own registered agent. An owner who is a Connecticut resident may serve personally; the entity as such may not.

Why Privacy Matters More in Connecticut

Connecticut's requirement that individual agents disclose their residential address creates a unique privacy risk. If you serve as your own agent, your home address is publicly searchable in the Secretary of State's database. Anyone — marketers, litigants, strangers — can find it with a simple entity search.

Using a professional service eliminates this exposure entirely. Our Connecticut address appears on every public filing. Your residence is never disclosed.

The Case for Professional Service

Beyond privacy, a professional registered agent provides:

Guaranteed availability. We are at our address every business day during required hours. No vacations, no sick days, no missed deliveries.

Same-day document processing. Every piece of mail is scanned and delivered electronically the day it arrives. You never lose response time.

Compliance infrastructure. Annual report reminders arrive before the March 31 deadline so the $80 filing never becomes a dissolution crisis.

Document permanence. Your online portal stores everything indefinitely. Need a notice from two years ago? It is there.
