In addition to the costs of a business formation service or hiring an attorney (which are optional, as we’ve discussed), there are other required and optional expenses when forming and maintaining a Connecticut business. You cannot form an LLC in Connecticut without filing the Certificate of Organization, the document that officially registers your business within the state. This filing costs $120 to submit.
Your LLC will also need to file the annual report every year. This form essentially keeps the state updated about some vital information about your business. It costs $80 to submit. Read more about Connecticut LLC costs.
We invite you to take a look at our guide to forming a limited liability company in Connecticut. This article walks you through the LLC formation process in this state step by step, helping ensure that you don’t miss any crucial elements.
One of the most important steps in forming a Connecticut LLC is choosing a business name. Once you come up with ideas for your name, you should search through the Secretary of State’s business entity database to make sure your desired name is available. For more information on conducting a business name search in Connecticut, check out our Connecticut business search article.
You can find online and hard copy options of the Connecticut Certificate of Organization on the state’s business website.
All LLCs operating in the state of Connecticut are required to submit an annual report to the Secretary of State. It’s due by March 31 each year, and it costs $80.
Chances are, you’ll require at least one license or permit to operate your LLC in compliance with Connecticut state law. For more information about business licenses and more in this state, check out Connecticut’s Licenses, Registrations, and Permits page here.
If you file online, you’ll typically have your Certificate of Organization processed in 2 to 3 business days. If you file a paper application, processing usually takes 7 to 10 business days. However, if the Secretary of State is busy, it could take up to several weeks. You can also expedite your order for an additional fee.

Unfortunately, not all businesses last forever. If the time comes when you need to close your LLC’s doors, you’ll need to do so in a manner consistent with the state’s regulations. That’s why we wrote our guide to Connecticut LLC dissolutions, so you can complete the process in a compliant manner.
If your LLC already exists in another state, you don’t actually need to “form” it in Connecticut. Instead, you’ll need to foreign-qualify the business in this state. This process is somewhat similar to LLC formation, but there are some crucial differences as well. Take a look at our guide to foreign qualifications in Connecticut for more information.
