How to File Connecticut LLC Certificate of Organization

A lot goes into the conception and planning of a new business. It is the Connecticut Certificate of Organization that makes the LLC official. Being prepared before sitting down to complete the application will help you finish it efficiently.

First, have all of the required information handy. You will be asked for the following information:

  • Name of the Connecticut LLC
  • Principal office address (PO Box not acceptable)
  • Mailing address (PO Box can be used.)
  • Name and address of registered agent
  • Name and address of individual filing
  • Name and address of manager or member (at least one needed)
  • Email address (for notification of annual report due date)

Second, the cost of filing the Certificate of Organization is $120, so have a credit card or check ready to go. Checks are payable to Secretary of the State.

Finally, processing time is typically between three and five business days for both online and hard copy filing. Expect longer wait times during heavier filing periods. Expedited processing (hard copy only) costs $50 and is completed within 24 hours.

Want Help Filing Your CT Certificate of Organization?

If you decide to use your time building your business rather than completing paperwork, but don’t want to spend the money on an attorney, an LLC registration company is a great compromise.

Lots of services are out there but do vary in perks offered, processing times (theirs, not the state’s), and price.

In general, a service will collect and review your information, prepare the documents, and send them to the Business Services Division of the Connecticut Secretary of the State. They will contact you when the Certificate of Organization has been filed.

One additional benefit offered by some services is a free year of registered agent service. Others offer order tracking or notifications of future legal requirements needed with the state.

After reviewing all the top formation services available, we found IncFile and Northwest Registered Agent the best overall options. While neither of them have as high brand power as the industry giant, LegalZoom, both services have great customer support, prices and offer a free registered agent.
