Forming an LLC in Connecticut

If you're considering forming an LLC, you'll want to make sure that you complete all of the necessary steps in the process. After all, a mistake in formation could lead to all kinds of costly problems down the road. This article discusses the process for forming an LLC in Connecticut, including links to forms and relevant statutes.

Forms for Connecticut LLC Formation

As with a corporation, forming an LLC in Connecticut consists of filing specific paperwork. For your convenience, FindLaw offers a Connecticut LLC Formation Package which has the forms you'll need to file your LLC in the state.

LLC Attributes

In Connecticut, you can form an LLC ("limited liability company") without many of the formalities of a corporation. "Limited liability company" refers to the advantage that owners have against the company's court judgments and debts. An LLC also offers tax advantages in the same way that a partnership does.

Professional Services LLCs

Connecticut also recognizes LLCs formed to provide specific professional services (such as LLCs for physicians or accountants). The difference with these PLLCs is that they require that the members must be licensed and authorized to render the professional services.

Overview of Forming an LLC in Connecticut

While the LLC formation requirements are similar in every state, each state has its own laws and treats the process a little differently. See the chart below for information on how to form an LLC in Connecticut, and the steps you'll need to take.


Connecticut General Statutes Title 34:

  • Section 34-102 (LLC name)
  • Section 34-103 (reservation of name)
  • Section 34-104 (statutory agent for service)
  • Section 34-106 (annual reports)
  • Section 34-110 (filing of documents)

Naming the LLC

Connecticut law requires that the LLC names must:

  • Contain the term "Limited Liability Company"; or
  • Approved abbreviations "L.L.C." or "LLC"; and
  • Be different from the names of existing businesses that are already registered with the Connecticut Secretary of State.

Check the Connecticut Secretary of State Name Database for name conflicts.

You may file an application with the Secretary of State to reserve your LLC name for 120 days. Along with paying a filing fee, you may file the application online or via postal mail.

Selecting a Registered Agent

All Connecticut LLCs must have an agent for service of process purposes if the business is ever sued.

The 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; or
  • A foreign business entity that has a certificate of authority to transact business in Connecticut.

Filing Certificate of Organization

You must file the Certificate of Organization with the Secretary of State. The filing (which includes fees) must include the following information:

  • The LLC's name and address;
  • The registered office's name and address;
  • The name of at least one manager or member; and
  • Whether the LLC is operated by a manager.

You may file online or via regular mail.

Creating an Operating Agreement

Connecticut law doesn't require operating agreements, but it's recommended that you create an operating agreement to promote more organized operations for your business.

Complying with Tax and Regulatory Requirements

If your LLC has more than one member, then you must apply for an Employer Identification Number (EIN).

Obtaining the Necessary Business Licenses/Permits

You may have to obtain local and state business licenses, depending on the type of business and the location.

Note: State laws are always subject to change through the passage of new legislation, rulings in the higher courts (including federal decisions), ballot initiatives, and other means. While we strive to provide the most current information available, please consult an attorney or conduct your own legal research to verify the state law(s) you are researching.

Foreign LLCs

All LLCs organized outside of the state must register with the Connecticut Secretary of State to do business in Connecticut. All foreign LLCs must appoint a registered agent for process of service who is physically located in Connecticut

Annual Reports

Part of maintaining your Connecticut LLC after formation is that you must file an annual report with the Connecticut Secretary of State online, accompanied by a filing fee. The due date is the anniversary month that the LLC was formed.
