How to Form an LLC in Connecticut

This guide to starting a Connecticut LLC provides step-by–step instructions for filing formation documents and obtaining tax IDs.


LLCs are the most popular business structure. This is because they are easy to start, inexpensive to set up and maintain, and allow owners flexibility. The legal form of your LLC creates your business, limits personal liability, gives you tax flexibility, and establishes your business. As you move through this process, you will be guided step-by-step.

    Your LLC must keep accurate records and books. Your LLC’s original articles of organization will be the first document you keep. Your LLC will create many other official documents such as:

    • Minutes of the meeting
    • Operating agreement
    • EIN verification letter
    • Amendments to and other filings made during the LLC’s lifetime


  5. You must create the Operating Agreement

    It is possible to use a template to draft an Operating Agreement. This document will serve as the governing document. It specifies the legalities of the LLC’s operation, such the annual meeting and the procedure for submitting it to creditors. The agreement will then be approved by you at your organizational meeting.

  6. Organize the Organizational Meeting

    The first meeting between members of an LLC is called the organizational meeting. In order to hold this meeting, you’ll need your operating agreements and the filed articles. Keep the minutes of this meeting.

  7. Get a federal employer identification number (EIN).

    EIN is required if the LLC will have more than one owner or hire employees. EIN is often required to open a bank or other financial account.

    • S-Corp can help owner-employees making more than $75,000 a year save on self-employment income taxes.
    • C-Corps face double taxation. First, the corporation pays income taxes and then the members pay distribution taxes. C-Corps offer low tax rates on retained earnings, which can be beneficial if you have more than $250,000 in profits per owner.
  10. Get business licenses and permits

    It is necessary to obtain the required licenses and permits in order for your business to be legally operated. It’s easy to search for the type of your business and whereabouts using the Small Business Administration Business License & Permit lookup tool.
