Forming an LLC in Connecticut


Located in the southern part of beautiful New England, Connecticut has the highest per capita and median household income in the U.S. Bordered by New York, Rhode Island and Massachusetts, the state was very influential in the formation of the U.S.

Today, finance, insurance and other industries are major contributors to the state’s economy. Combined with a high disposable income, this makes Connecticut an ideal place for entrepreneurs. For most business owners, the fastest and easiest way to start a business in Connecticut is by creating a Connecticut LLC.

A Limited Liability Company (LLC) is a type of business entity that’s ideal for startups and small- to medium-sized businesses. You get the advantages and protections of larger CT corporations but with much simpler rules and regulations.

Briefly, the benefits of starting a Connecticut LLC include:

  • Separating and limiting your personal liability from your business liability and debts
  • Quick and simple filing, management, compliance, regulation and administration of your Connecticut LLC
  • Easy tax filing and potential advantages for your tax treatment

Start a Connecticut LLC in Six Quick Steps

This guide has plenty of information on how to form your Connecticut LLC, but you can break down the basics of forming a business in CT into just a few simple steps.

STEP 1: Gather Information for Your Members

First, you need to gather basic information about your LLC, including the names and addresses of the managers or members. The LLC members are typically the people who own and run the business. They are also the ones who can take profits out of the business to pay themselves.

STEP 2: Choose a Unique Business Name for Your Connecticut LLC

You will need a distinctive and original name for your Connecticut LLC that’s not used by any other business in CT. To find out if another company is using your chosen business name, carry out a Connecticut business entity name search on the CT Secretary of State website.

There are a few rules you’ll need to follow when choosing an LLC name. You can find out more in our guide to searching for and naming your Connecticut LLC.

STEP 3: Provide an Official Address for Your CT LLC

Every Connecticut LLC must have a designated street address. That could be your home address (if you’re running the company from your residence), your company’s office building or any physical address of your preference. The address must be inside the state of Connecticut, but it cannot be a P.O. Box.

STEP 4: STEP 4: Assign a Registered Agent for Your Connecticut LLC

Every CT LLC or corporation must have a “Registered Agent.” This is an official position; the Registered Agent is someone who receives official legal and tax correspondence and has responsibility for filing reports with the Connecticut Secretary of State.

This position can be filled by you, another manager in the business or a dedicated Registered Agent service. Your CT Registered Agent must have a physical street address in Connecticut and must be present to receive important documents for your company during business hours.

At Incfile, all of our packages include a Connecticut Registered Agent service that is free for the first year and just $119 per year afterward. We also have a dashboard where you can log in and easily view any document your Registered Agent has received on your behalf.

STEP 5: Get an Employee Identification Number (EIN) from the Internal Revenue Service

You will need an EIN to identify your business with the IRS. You use this number when filing and paying taxes or when submitting payroll information and payments for your employees. You can obtain one directly from the IRS, or we can get one for you as part of the Connecticut LLC business formation process.

STEP 6: File a Certificate of Organization with the Connecticut Secretary of State

Once you've gathered all the information for your Connecticut LLC, you’ll need to file a formal document with the CT Secretary of State. Known in some states as “Articles of Organization,” in CT, this document is called your “Certificate of Organization,” and filing the document creates your Connecticut LLC. Here’s what is typically included:

  • Your business name and addresses
  • Details of your Registered Agent
  • Names of managers or members of the LLC at the time of filing
  • Addresses of managers or members of the LLC at the time of filing
  • Name of the incorporator

You can file your Connecticut LLC Certificate of Organization online, mail in a form or have Incfile do it on your behalf. There is a fee to file and start an LLC in Connecticut. You only need to file your Certificate of Organization once.
