Entity Name and Address

Having a creative and smart business name is important but not as important as having a legally correct name.

When you choose a name for your business, you have to make sure the name:

  • Meets Connecticut naming guidelines. 
  • Is not already in use by another business in Connecticut. 

Follow the Connecticut Naming Guidelines:

  • Your name must contain the words "limited liability company" or the abbreviation "L.L.C." or "LLC." "Limited" may be abbreviated as "Ltd.," and "company" may be abbreviated as "Co."
  • Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
  • Your name must be distinguishable from any existing business in your state. We will help with this step in the search for your business name section below.
  • Your name must not include any words that imply that the company is organized for anything other than its permitted purpose.
    In some states, certain words (e.g., Bank, Attorney, University) may require additional paperwork and a licensed individual to be part of your LLC.

Check Name Availability:

Is your name available in Connecticut? Make sure the name you want isn't already taken by doing a name search on the Connecticut Secretary of State website.

Registered Agent and Registered Office

A registered agent accepts and sends legal documents on your LLC's behalf. When you register your Connecticut LLC, you are required to list your registered agent and your registered office. 

Your registered agent can be anyone 18 years or older that lives in Connecticut. Your registered agent must always be available at the registered office during regular business hours. Your registered office address cannot be a P.O. box.

To learn more about choosing a Connecticut registered agent, read our How to Choose a Connecticut Registered Agent guide.

Steps After Your Connecticut LLC Is Officially Formed

Once you’ve filed your Certificate of Organization, you should take the following steps:

Create an Operating Agreement

A Connecticut LLC Operating Agreement is a legal document that outlines the ownership structure and member roles of your LLC.

In Connecticut, you aren't required to have an Operating Agreement to officially form an LLC, but it's still a good idea to have one. You can start your operating agreement before, during, or after you file your Certificate of Organization.

Your operating agreement will be kept in your LLC's private business records; you do not file it with the state.

Use our free Operating Agreement Tool to draft a customized operating agreement for your LLC.

Get an EIN

An Employer Identification Number (EIN) is like a social security number for your LLC. You will need an EIN if you want to hire employees or open business bank accounts.

You can get your EIN for free through the IRS website, via fax, or by mail. If you would like to learn more about EINs and how they can benefit your LLC, read our What is an EIN article.

Open a Business Bank Account

Using dedicated business banking and credit accounts is essential to protect your business' corporate veil. When your personal and business accounts are mixed, your personal assets (your home, car, and other valuables) are at risk in the event your LLC is sued.

Get Licenses and Permits

When you are registering an LLC, you need to determine if your business needs any licenses or permits to remain compliant. On the federal level, there are a handful of business activities that require licenses or permits.
