What A Connecticut LLC Is (and Why People Form One)

LLCs are the workhorse small-business entity — they shield the owner's personal assets and pass income straight to the owner's tax return. Among Connecticut small companies, the LLC is the small-business entity of choice because it offers liability protection paired with simple tax filing.

Our LLC formation service	$199 one-time

How to Form Your Connecticut LLC, Step by Step

1. Settle on a Compliant LLC Name

Your chosen LLC name in Connecticut needs an LLC suffix and needs to be clearly different from anything already on file at the state. Confirm the name is open with Connecticut Secretary of State's entity search. Doing so first saves a rejected filing and the re-do fee.

Restricted words include 'bank,' 'insurance,' 'trust,' and anything suggesting a government agency. Pick a different angle if you're none of those things.

2. Select Your Registered Agent

The state-required agent for your LLC has to maintain a physical address in Connecticut and be reachable all through the business day, every business day. The agent's information lives on the public record at Connecticut Secretary of State and remains there so long as the LLC exists.

Our $99/year plan covers the agent role in Connecticut — we handle the public side of the agent role for you.

3. Send the Articles of Organization to Connecticut Secretary of State

This is the moment the LLC becomes real: deliver the Articles to Connecticut Secretary of State with payment of $120 to the state. The filing covers the LLC's name, the main business address, the RA's name and address, manager- or member-managed designation, and the organizer(s) doing the filing.

Connecticut Secretary of State has an online portal (Connecticut Secretary of State's filing website) — file there for the quickest turnaround.

Approval normally comes back in 5-10 business days. A pay-for-speed option is often available for an added fee.

4. Prepare an Operating Agreement

The state doesn't make you file an operating agreement, but you need one anyway: it's the internal rulebook for the LLC. The agreement defines ownership, distributions, management authority, voting rules, and exit procedures. If no agreement exists, Connecticut's statutory defaults govern. Those defaults aren't designed for your specific business.

5. Get an EIN from the IRS

The EIN is your LLC's federal tax ID. It's referenced by banks, payroll services, and the IRS. Use the IRS website to apply. It takes roughly ten minutes, and your EIN issues at the end.

Don't bother paying for an EIN through a third party. EINs are free from the IRS via a brief form.

6. Maintain Compliance Going Forward

Filing is only the beginning. Maintaining the LLC requires ongoing attention to:

• Keep the agent appointment at a physical Connecticut address at all times
• Lodge the state's annual filing on schedule each year
• Run with a clean split between the LLC's accounts and your personal accounts (its own bank account, its own books)
• Stay current with tax obligations across the federal level as well as state level by their deadlines

Missed obligations can lead to dissolution at Connecticut Secretary of State's discretion — at which point the liability shield is gone until you reinstate.

The Registered Agent Requirement

There's no way around the agent requirement in Connecticut — each LLC, regardless of size, needs one. Agent specifications:

• Have on file a brick-and-mortar address in Connecticut (a PO box alone isn't enough)
• Be present all through normal business hours for service of process
• Move along state mail and lawsuits promptly to keep response windows intact

Using your home address as agent address makes it part of the state record. Once it's listed, anyone running a Connecticut entity search can find it.

Our agent product in Connecticut is $99 a year. List our information on the filing and your personal address never sees the public record.
