How to File a Certificate of Organization in Connecticut

In Connecticut, as in most states, the primary step in creating a limited liability company (LLC) is to file a certificate of organization with the state. This is an absolutely crucial document that helps define your business, so it’s important to do it correctly.

An LLC is a business entity that offers liability protection for owners, as well as pass-through taxation, much like a sole proprietorship. 

What is a Certificate of Organization?

The certificate of organization is a legal document you need to file with the state to form your LLC. It will specify details about your company and establish your LLC as an officially registered business entity in Connecticut. 

The document is similar to the articles of incorporation you would file to form a corporation instead of an LLC.
