Quick Reference

When forming an LLC business structure, you first need to file the Certificate of Organization with the Connecticut Secretary of the State. This is a legal document that officially launches your new LLC into existence. After filing, the business can obtain an Employer Identification Number (EIN), state tax number, open a bank account, and register for business licenses.

Some of the required information needed to complete the Certificate of Organization in Connecticut includes:

  • Your new company’s name. When filling out this information be sure to include the entity designator at the end of the business name. The allowed designator can be Limited Liability Company, Limited Liability Co., Ltd. Liability Company, Ltd. Liability Co., LLC,  L.L.C.

    If you haven’t verified already, be sure to do a name search with the Connecticut Secretary of the State to be sure the LLC name is available.

  • Address of the principal office address. This may be, but is not required to be, the actual place of the business to the physical street address, or the main location where the business records are kept. A physical address must be used as P.O. Boxes are not acceptable.
  • Mailing address. Which may be the same as the principal office address or could be any address where you would prefer notifications from the Secretary of the State to go. Unlike the principal office address, a P.O. Box can be used.
  • Name and address of your company’s registered agent. A registered agent is a party authorized to receive and accept service of process on behalf of your LLC. You may act as your registered agent or you may authorize an individual outside of the LLC or another company authorized by your state to act as a registered agent. The registered agent must use a physical street address in Connecticut.
  • Information about the LLC members and managers. In the Certificate of Organization, you will need to include contact information with the names and mailing addresses of the LLC members.
  • Information about the LLC organizers. Include the name(s) of the initial organizers of the LLC (people helping with the formation of the entity). This is often the owner, but can be anyone.
  • Fiscal Year Closing Month. This is indicating which month the LLC will use for its ending tax month.  Most LLCs will use December.
  • Management of the LLC. In the Certificate of Organization, you will need to indicate whether the management structure is either member-managed or manager-managed.
  • NAICS Code. A NAICS code (North American Industrial Classification System) is a system to identify businesses operating in a given industry.

The filing fee for the Certificate of Organization is $120.


In addition to the Certificate of Organization, many LLCs will want to draft an operating agreement is an internal document outlining the governing structure and operating guidelines of the entity along with the responsibilities of the members.
