How to Form an LLC in Connecticut

Limited liability companies (LLCs) are a type of business structure that is popular with small business owners. One of the main reasons to start an LLC is for the liability protection. With limited liability protection, LLC owners are only responsible for the company's liabilities up to the amount they invested in the company. This is a big advantage because LLC owners' personal assets are not at risk for business debts and liabilities.

An LLC also offers the advantage of pass-through taxation in the same way that a partnership does. With pass-through taxation, LLC members report the company's profits on their personal tax returns. This can be preferable to corporate taxation. When corporations pay taxes, they can be subject to taxation both at the corporate and the personal level. This is known as double taxation.

If you would like to benefit from the personal liability protection and simplicity of a Connecticut LLC, just follow along with the seven steps below.

Step One: Choose a Unique Name for Your LLC

To make your business stand out from the competition, you should choose a distinctive and memorable LLC name. You will also need to follow Connecticut's LLC naming rules.

According to the Connecticut Uniform Limited Liability Company Act, your LLC's name must:

  • Contain the term "Limited Liability Company" or the approved abbreviations "L.L.C." or "LLC." If you like, you can shorten “limited" to “Ltd." and “company" to “co."
  • Be different from the names of existing businesses that are already registered with the Connecticut Secretary of the State.

To find out if your desired name is available in Connecticut, you should run a name search at the Connecticut Secretary of the State website. If another business is already using your name, you will need to find a different one.

If no other Connecticut businesses have registered your name, you should continue searching. The U.S. Patent and Trademark Office (USPTO) provides a searchable trademark database. To avoid infringing on another company's trademark, you will need to make sure that your business name does not match another one in this database.

Step Two: Select a Connecticut Registered Agent

Before you start an LLC in Connecticut, you must select a registered agent. A registered agent is a person or entity who agrees to accept legal papers for the business. This includes service of process if someone sues your LLC.

Your registered agent may be one of the following:

  • An individual who is a full-time resident of Connecticut (including an LLC member or manager)
  • A Connecticut business entity
  • A foreign business entity that has a certificate of authority to transact business in Connecticut
  • The entity or individual who acts as your registered agent must have a physical address in Connecticut. A P.O. box will not suffice.

If none of your LLC members are willing to act as registered agent, you should consider a registered agent service. With a registered agent service, you pay a fee to another individual or business to accept legal papers for the business. You can easily find options for this service by doing a simple internet search.

Step Three: File a Certificate of Organization

To start your LLC, you will need to file a Certificate of Organization with the state and submit a $120 filing fee.

A Certificate of Organization is a legal document that provides fundamental information about your company to the state of Connecticut. In other states, this is called articles of organization.

The Certificate of Organization filing must include the following basic information:

  • Your LLC's name and address
  • The registered agent's name and address
  • The name of at least one manager or member
  • A statement about whether the LLC is manager-managed or member-managed

You can file your Certificate of Organization online at the Connecticut Secretary of the State website. There, you will need to sign in or create a new account. If you prefer, you can file by mail.

You should make a note of your login credentials if you file online. You can later use these to file your LLC's annual report.

Step Four: Create an Operating Agreement

Connecticut law does not require operating agreements, but it's a good idea to have one. An LLC operating agreement shouldn't be confused with the certificate of organization. The operating agreement is a contract among your LLC members, similar to corporate bylaws. It's an internal document that you will not file with the state. You will use it to form a contract on issues such as:

Having an operating agreement promotes more organized operations for your business. It may also help to avoid future disagreements among members. Even single-member LLCs should have operating agreements. Although single-member LLCs don't have to worry about disagreements among members, an operating agreement helps to add legitimacy to their limited liability status. Further, you may need to show this document to certain professionals to obtain services for your business.

Step Five: Get an Employer Identification Number

An Employer Identification Number (an EIN) is a unique number that the Internal Revenue Service (IRS) issues. It helps to identify your company, especially for tax purposes. You can think of it as a Social Security Number for businesses.

Unless you have a single-member LLC with no employees, you will need to get an EIN. You will use your EIN to file taxes, pay employees, open a business bank account, and apply for business credit cards.

You can file for a free EIN by mail, fax, or online with the IRS.

Step Six: Comply with Tax and Licensing Requirements

Depending on the location and nature of your business, your tax and licensing requirements will vary. You may need local, state, or federal business licenses.

Licensing Requirements

If you think you may need a federal license, you should visit the Small Business Administration (SBA) website. There, you can find comprehensive information about the types of businesses that must apply for federal licenses.

To learn about your state licensing requirements, you should visit Connecticut State's online License and Permit Center.

For local permits, you should contact your city or county clerk.

Tax Requirements

To avoid future legal problems and audits, you should make sure to file your taxes accurately and promptly.

Your federal tax obligations will include self-employment tax and personal income taxes. You can obtain comprehensive information about your federal tax obligations from the IRS website.

To learn about your state tax obligations, you should visit the Connecticut Department of Revenue Services website. Your state taxes will depend on the type of business you run. For example, if you are selling goods, you may need to collect sales taxes. Further, if you have employees, you will need to register for withholding taxes.

Step Seven: Submit Annual LLC Reports

To keep your Connecticut LLC in good standing, you must submit a yearly report to the Secretary of the State. An annual report confirms the foundational information about your LLC. This includes the LLC's name and address, information about the registered agent, and other basic details. You will find this to be very similar to the details you provided in your Certificate of Organization.

Connecticut LLC annual reports are due between January 1st and April 1st of every year. You will submit your first one before April 1st of the calendar year after you created your LLC. The Secretary of the State's office will send you an email or a postcard to remind you of this about a month prior to your report deadline.

You can submit your annual report at At the time of this writing, the filing fee is $80.
