How to file the Connecticut Certificate of Organization by mail and form your LLC

Articles of OrganizationTo form an LLC in Connecticut, you need to file a Certificate of Organization with the Connecticut Secretary of State. This document officially registers and creates your Connecticut LLC under Chapter 613a of the Connecticut Uniform LLC Act.

You can file your Connecticut LLC’s Certificate of Organization with the state in 1 of 2 ways:

1. By mail: the filing fee is $120, and your Connecticut LLC will usually be approved in 7-10 business days. However, if their office is backed up, approval time can take 3-5 weeks.

2. Online: the filing fee is $120 and your Connecticut LLC will be approved in 2-3 business days (whether or not their office is backed up).

Note: Filing times may take longer due to the current global situation and government delays. For the most up-to-date LLC processing times, check how long does it take to get an LLC in Connecticut.

Important: The instructions on this page are for the mail filing only. In Connecticut, we actually recommend the online filing instead as the approval time is much faster and you’ll get a free copy of your approved Certificate of Organization (you have to pay $40 extra for this if you file by mail).

If you want to file your Connecticut LLC online, please see this lesson.

Note: If you hired a Commercial Registered Agent and you’re filing by mail, you’ll need to contact your agent. They’ll first need to sign the Certificate of Organization and then send it to you.

Filing Party

Enter your name and your mailing address. The Connecticut Secretary of State will send the Acceptance Letter to this address.

1. Name of Limited Liability Company

Enter your desired Connecticut LLC name exactly as you would like it, including your preferred capitalization, as well as the designator at the end.

Connecticut law allows for the following designators (endings):

• L.L.C.
• Ltd. Liability Co.
• Ltd. Liability Company
• Limited Liability Co.
• Limited Liability Company

Tip: If you’re not sure which designator to choose, “LLC” is the easiest and most common.

Comma in LLC name:
You can use a comma in your Connecticut LLC name or you can leave it out. For example, “John Timber & Sons LLC” and “John Timber & Sons, LLC” are both acceptable by the state.

2. LLC’s Principal Office Address

Enter your LLC’s principal office address. PO boxes are not allowed. It must be a street address. You can use your home address, office address, or the address of your Registered Agent (if they allow it). This address can be located in Connecticut, but it doesn’t have to be.

3. LLC’s Mailing Address

Enter your LLC’s mailing address. PO boxes are allowed here. This address can be located in Connecticut, but it doesn’t have to be. If your mailing address and principal office address are the same, just re-enter the same address again.

4. Appointment of Registered Agent

If your Registered Agent is an individual:

Check off “A” (leave subsection “B” on page 2 blank), enter their full name, have them sign to the right, and then enter their business address, Connecticut residence address, and Connecticut mailing address.

If you hired a Commercial Registered Agent:

As mentioned earlier, you’ll need to contact your Commercial Registered Agent since they’ll first need to sign the Certificate of Organization and then send it to you.

The following items should be completed by your agent, but double-check the following:

  • section “B” is checked off (subsection “A” above is blank)
  • name of agent is entered
  • Connecticut business address and Connecticut mailing address are complete
  • the agent must sign and enter their title

5. Manager or Member Information

Enter the name and address of at least one of your LLC’s members or managers.

If you need to add more than 2 members/managers, please use this additional members/managers form and include it with your filing.

6. Entity Email Address

Enter your email address here. This field is optional, so you can leave it blank if you prefer. The Secretary of State will send Annual Report reminders to this email address.

7. Execution, Name of Organizer, and Signature

Enter the date and the Organizer’s name and signature. The LLC Organizer is the person who is filing the Certificate of Organization with the Connecticut Secretary of State.

Connecticut LLC Mailing Instructions

Business Services Division

Connecticut LLC Approval

After the state processes and approves your Connecticut LLC, they will mail you back an Acceptance Letter. Your Acceptance Letter will contain your Business ID Number.

The state does not mail back a copy of your approved Certificate of Organization. If you’d like to order a copy, you can request a plain copy ($40) or a certified copy ($55). Please see our Ordering Copies instructions.
