Registering an LLC in Connecticut is as easy as six steps. 

Forming an LLC in Connecticut is a straightforward process. Follow these six steps to register your LLC in the state:

  1. Name Your Connecticut LLC 
  2. Appoint a Registered Agent
  3. File a Certificate of Organization
  4. Create an Operating Agreement
  5. Obtain an EIN and Handle Taxes

Step 1: Name Your Connecticut LLC

The first step toward forming your LLC in Connecticut is to choose a business name

Naming an LLC in Connecticut requires a few rules: 

  • Your name must be unique and distinguishable from any other business entity in the state
  • It must include “Limited Liability Company” or one of its abbreviations 
  • Your name must not include words that imply government affiliation 

For the full list of naming requirements for Connecticut LLCs, review the Uniform Limited Liability Company Act

To ensure your business name is unique, you will need to complete a business records search on the Official Connecticut State website.

Step 2: Appoint a Registered Agent

When registering an LLC in Connecticut, you are required to appoint a registered agent. A registered agent in Connecticut is an individual or business entity that is responsible for receiving important information and documents on behalf of your company, such as tax forms or notice of lawsuits. 

The appointed registered agent must: 

  • Be a full-time resident of Connecticut or a business entity authorized to conduct business in the state
  • Have a physical address in Connecticut 
  • Not be the LLC itself 

Who is Eligible to Serve as a Registered Agent in Connecticut?

To register an LLC in Connecticut, it is important to have a registered agent who is eligible to serve in this role. The registered agent can be the LLC owner, an employee of the company, or even a friend or family member. Alternatively, you can choose to hire a registered agent service. 

Step 3: File a Certificate of Organization 

To officially register an LLC in Connecticut, you will need to file a Certificate of Organization with the Secretary of State. You can complete this filing online or by submitting this form by mail or in person. 

The filing fee is $120

We recommend having the following details prepared:

  • Name and phone number of the LLC organizer
  • Your LLC name, principal address, and mailing address 
  • The name, address, and signature of your LLC’s registered agent 
  • Your LLC’s NAICS code 
  • The names, addresses, and email addresses of all LLC members 

What Is an NAICS Code? 

A North American Industry Classification System (NAICS) code is required to register an LLC in Connecticut. This is a six-digit code that identifies the type of trade a business engages in. 

Quick Note: If you have already formed your business in another state, you will need to register as a Connecticut Foreign LLC by submitting a Foreign Registration Statement online or by mail. The filing fee is $120.

Step 4: Create an Operating Agreement 

You aren’t required to create an operating agreement to register an LLC in Connecticut but it is still a good idea. 

An operating agreement outlines the day-to-day operations and ownership details of your company. By having an operating agreement in place, you can ensure that all LLC members are on the same page and help to prevent future conflicts. 

Step 5: Obtain an EIN and Handle Taxes

Next, you need to obtain an Employer Identification Number (EIN) from the Internal Revenue Service (IRS).

An EIN operates similarly to a social security number but for your business. It allows the IRS to track and identify your business for tax reporting purposes. Plus, with an EIN you can hire employees and open a business bank account. 

You can obtain an EIN for free on the IRS website

Additionally, it is important at this stage to identify any additional tax requirements for your business by visiting the Connecticut Official State website

Step 6: File a Beneficial Ownership Information Report

To register an LLC in Connecticut, you must follow a series of steps. One essential step in this process is filing a Beneficial Ownership Information (BOI) report with the US Financial Crimes Enforcement Network (FinCEN). 

Newly formed LLCs must complete this filing within 90 days of formation, while existing LLCs must do so before January 1st, 2025. 

Failure to file this report on time will result in a $500 per day fine.

Filing a BOI report can be done online for free on the FinCen website
