Connecticut Registered Agent for Out-of-State Businesses

If your business is formed in another state but does business in Connecticut, you're considered a "foreign" entity in Connecticut — and you'll need to register here through a process called foreign qualification. A required step in that process is naming a Connecticut registered agent.

What "Foreign" Actually Means

In legal language, "foreign" doesn't mean international — it just means out-of-state. An LLC formed in Delaware that opens an office in Connecticut is a "foreign LLC" from Connecticut's perspective. The same applies to corporations and other entity types.

Connecticut law (section 34-275a) bars a foreign LLC from transacting business here until it registers with the Secretary of the State. Section 34-275d lists twelve things that don't count, including member meetings, financial accounts, sales through independent contractors, an isolated transaction, owning property with nothing more, voting shares you own, and interstate commerce. Unlike many states, Connecticut puts no day limit on that isolated transaction.

What a Connecticut Registered Agent Does for a Foreign Entity

Your Connecticut registered agent is the legal point of contact for your foreign entity in Connecticut. The agent:

• Receives service of process if your business is sued in Connecticut
• Is a Connecticut resident or a business registered here with a Connecticut address, and signs to accept the appointment
• Can't be your LLC itself, though a manager or member who lives in Connecticut can serve
• Can even be the Secretary of the State, an option open only to foreign companies, which forwards lawsuits by certified mail

Connecticut is one of the toughest states on late registration. After your first 90 days of doing business, the state can levy $300 for every month or part of a month you operated without registering, on top of the fees, taxes, and interest you'd have owed. Its Foreign Investigations Unit sends demand letters. Connecticut courts also won't hear a suit it brings until it registers; its contracts survive, and defending itself stays possible.

How to Foreign-Qualify in Connecticut

The general process for registering an out-of-state entity in Connecticut:

1. Get a certificate of existence. Since January 1, 2025, Connecticut has required one from your home state (your state may label it good standing). The form's instructions say it must arrive within 90 days of being issued.

2. Designate a Connecticut registered agent. You can use a commercial registered agent service or appoint an individual who lives in Connecticut.

3. File the Foreign Registration Statement ($120). File online with a Business.CT.gov account or on paper to Hartford; both cost $120, and a $50 expedite is available online only. The form asks for an entity email, a NAICS code, and at least one manager or member. When your name is unavailable here, item 2 takes an alternate name for use in Connecticut.

4. File the $80 annual report online. Starting the year after you register, the report window runs from January 1 through March 31. Reports are online only, and the state emails a reminder about a month before. Skip it, and Connecticut may revoke your registration once 20 days have passed after its emailed warning.

Filing fees and form names change. Always check current requirements directly with the Connecticut Secretary of the State at https://portal.ct.gov/sots before filing.
