Follow our How to Start an LLC in Connecticut guide below to get started.

Steps to form an L L C in Connecticut

Step 1: Create a Name for Your Connecticut LLC

Before you register your LLC, you'll need to come up with a name. Your business name needs to be catchy for branding purposes and legitimate for legal purposes.

We go into depth on this topic in our LLC naming guide. We’ll go over the basics below.

Naming Your LLC

First, brainstorm some possibilities. Use our LLC name generator to get the ideas flowing.

Next, make sure your name meets Connecticut guidelines:

  • it contains the words limited liability company, limited company, LLC, or L.L.C.
  • it doesn't contain restricted words or phrases (these often include words like bank, attorney, and university) without proper approval
  • it doesn't contain the words corporation, incorporated, or the abbreviations corp. or inc.
  • it's distinguishable from any other entity or trade name registered in Connecticut
  • full list of Connecticut naming guidelines

Next, do a Connecticut LLC name search with the Secretary of State to find out if your name is available in Connecticut.

If your business name is available and meets guidelines, you’ll be able to register it when you file your Connecticut Certificate of Organization with the Secretary of State.

Is the URL available? Before you commit 100% to a name, check to see if there’s a good web domain available.

We recommend buying your domain right away because even if launching a business website isn’t on your radar right now, it will be soon.

Once you register a domain name for your LLC, consider setting up a business phone system to establish credibility and enhance your customer service. Nextiva provides a plethora of useful features and a quick, easy setup. Try Nextiva.

Step 2: Appoint a Connecticut LLC Registered Agent

When you file your Articles of Organization, you'll need to list a registered agent.

A registered agent's job is to accept legal documents like service of process and tax notices for your LLC.

Your registered agent can be a person or a registered agent service. You can act as your own registered agent, but many business owners choose to use a registered agent service.

Here are a few things to think about before you decide to act as your own registered agent:

  • You’ll need to be available during normal (9 am - 5 pm) business hours at the address you provide
  • If you run your business from home, you’ll have to make your personal address public
  • You could be served with a lawsuit in front of your family or coworkers

Recommended: Most registered agent services offer a year of registered agent service free when you form an LLC with them. 

Step 3: File a Certificate of Organization

It’s time to officially form your LLC by filing your Certificate of Organization with the Connecticut Secretary of State.

You can file online with CT Business One Stop or fill out a hard copy of the CT Certificate of Organization and mail it in or deliver it in person. The filing fee is $120. 

Recommended: Now is a good time to decide if your LLC will be member-managed vs manager-managed.

You'll need to know the following information to complete each Article:

  1. Entity Name and Address
  2. Registered Agent Name and Registered Office Address
  3. Governing Authority Type (LLC Management Structure)

For more detailed help with completing the form, visit our Connecticut Certificate of Organization guide.

Mail Your Certificate of Organization:

Send the form and payment (payable to the Secretary of State) to:

Business Service Division
Connecticut Secretary of the State
P.O. Box 150470
Hartford, CT 06115

Submit In Person: 

Business Service Division
Connecticut Secretary of the State
165 Capitol Ave., Suite 1000
Hartford, CT 06106

How long does it take to get an LLC approved? LLC processing time is 3 to 5 business days, but can be expedited for an additional fee.

Step 4: Create A Connecticut LLC Operating Agreement

Creating a Connecticut LLC operating agreement is the only way to legally lock down your LLC’s management and ownership structure. Having this document in place will give you something to return to if a dispute or lawsuit arises. 

Even single-member LLCs benefit from having an operating agreement.

Your operating agreement should outline the following:

  • Each member’s responsibilities
  • How new members will be admitted
  • How existing members may transfer or terminate their membership
  • How profits and dividends will be distributed

You can add as many provisions as you want, as long as they don't conflict with Connecticut business law. Take a look at our What is an Operating Agreement guide to learn more.

Step 5: Get an EIN

An Employer Identification Number (EIN) is like a Social Security number (SSN) for your company. The IRS and the state of Connecticut will use this number to track your business activity.

Your EIN will come in handy when it’s time to:

  • Open a business bank account
  • File Federal and State taxes
  • Hire employees

The best way to get an EIN for your LLC in Connecticut is by using the free online application on the IRS website.
