How to Start an LLC in Connecticut

Starting an LLC in Connecticut Is Easy With These 5 Steps

STEP 1: Name your Connecticut LLC

Choosing a company name is the first and most important step of forming an LLC in Connecticut. Be sure to choose a name that complies with Connecticut naming requirements and is easily searchable by potential clients.

1. Follow the naming guidelines:

• Your name must include the phrase “limited liability company” or one of its abbreviations (LLC or L.L.C.).
• Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
• Restricted words (e.g. Bank, Attorney, University) may require additional paperwork and a licensed individual, such as a doctor or lawyer, to be part of your LLC.
• Your name must be distinguishable from any other Connecticut limited liability company, corporation, limited liability partnership, or limited partnership.

2. Is the name available in Connecticut? Make sure the name you want isn't already taken by doing a Business Registry Search on the Connecticut Secretary of State's website.

To learn more about searching for a Connecticut LLC name, read our full guide.

3. Is the URL available? We recommend that you check online to see if your business name is available as a web domain. Even if you don't plan to make a business website today, you may want to buy the URL in order to prevent others from acquiring it.

Now that you have verified your name and secured the URL you may select a professional service to complete the LLC formation process for you. We recommend using a professional service:

• Tailor Brands ($0 + State Fees)

STEP 2: Choose a Registered Agent in Connecticut

You are required to nominate a registered agent for your Connecticut LLC.

What is a registered agent? A registered agent is an individual or business entity responsible for receiving important tax forms, legal documents, notice of lawsuits, and official government correspondence on behalf of your business. Think of your registered agent as your business's point of contact with the state.

Who can be a registered agent? A registered agent must be a resident of Connecticut or a corporation, such as a registered agent service, authorized to transact business in Connecticut. You may elect an individual within the company including yourself.

Recommended: Northwest provides the first year of registered agent service free with LLC formation ($29 + State Fees)

STEP 3: File the Connecticut LLC Certificate of Organization

To register your Connecticut LLC, you will need to file the Certificate of Organization with the Secretary of State. You can apply online, by mail, or in person.

Now is a good time to determine whether your LLC will be member-managed vs. manager-managed.

You'll also need to know your NAICS Code for LLC number (Connecticut requires it).

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

If you’re expanding your existing LLC to the state of Connecticut, you will need to form a Foreign LLC.

Connecticut NAICS Requirement

When filing the Connecticut LLC formation documents you will see that you are required to include your NAICS code. The North American Industry Classification System (NAICS) consists of 6-digit codes given to a business depending on the type of trade it engages in. You can look up the NAICS code for your type of business by using our NAICS Code Lookup Tool.

STEP 4: Create a Connecticut LLC Operating Agreement

An operating agreement is not required for a Connecticut LLC, but it's a good practice to have one.

What is an operating agreement? An operating agreement is a legal document outlining the ownership and operating procedures of an LLC.

Why are operating agreements important? A comprehensive operating agreement ensures that all business owners are on the same page and reduces the risk of future conflict.

For more information on operating agreements, read our Connecticut LLC operating agreement guide.

STEP 5: Get a Connecticut LLC EIN

What is an EIN? EIN stands for Employer Identification Number. EINs are a nine-digit number assigned by the Internal Revenue Service (IRS) to help identify businesses for tax purposes. It is essentially a Social Security number for a business.

An EIN is sometimes referred to as a Federal Employer Identification Number (FEIN) or Federal Tax Identification Number (FTIN).

Why do I need an EIN? An EIN is required to:

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

What if I already have an EIN for my sole proprietorship? The IRS requires that sole proprietorships get a new EIN when converting to an LLC.

Where do I get an EIN? You can get an EIN for free from the IRS. Getting an EIN is an easy process that can be done online or by mail.

FOR INTERNATIONAL EIN APPLICANTS: You do not need a SSN to get an EIN. For more information, read our How to Get an EIN as a Foreign Person guide.
