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.

Here are the steps you’ll need to take to create your new business entity:
- Gather the required information about your business.
- Entity Name
- Entity Address

Once you create an account, choose “Start Your Business” from the homepage, then choose “Register Your Business”. You will then be brought to the beginning of the online form. You will be asked to input your business type and legal structure (choose LLC). Click “Next” on each page.

If you already paid to reserve a business name, enter it on the next screen. If you did, click “yes”. The information should already be stored in your online account and it will populate automatically. If you did not, click “no” and you will be prompted to register.
On the following screens, you’ll input your NAICS code, principal office contact information, and business agent information. You will also be asked to upload any additional documentation (this is not mandatory). The last screen provides you with a chance to review your data. If everything looks correct, click the “Proceed to Payment” button.
When filling out your articles of organization form, be sure to double-check that all the information is accurate and up-to-date. Maybe you’ve just moved, or use your middle initial in official documents, such as with your bank account. If you get it wrong now, changing it later can be a real pain. So accuracy is crucial.
- File Certificate of Organization – The final step in the process is to submit payment through the website’s payment screen or mail in all documentation. The filing fee in Connecticut is $120.
