Note: Connecticut changed their LLC laws in 2017 (amending Chapter 613a of the LLC Act). The form “Articles of Organization” is now called the “Certificate of Organization” and “Statutory Agent” is now called “Registered Agent“.

In this lesson, we will walk you through filing your Certificate of Organization with the Connecticut Secretary of State. This is the document that officially forms your Connecticut LLC and allows you to do business in the state.

You can file your Certificate of Organization by mail or online. In both cases, the Connecticut LLC filing fee $120.

• If you file by mail, LLC approval time can be as quick as 7-10 business days. However, if their office is backed up, approval time can take 3-5 weeks.

• If you file online, LLC approval time takes 2-3 business days (regardless of whether or not their office is backed up).

Note: The “LLC filing fee” (the fee to create a Connecticut LLC) is the same thing as the “Certificate of Organization fee”. The Certificate of Organization is the document, that once approved by the Secretary of State’s office, creates your Connecticut LLC.

Our Recommendation: We recommend filing your Certificate of Organization online as the approval time is much quicker. The state will also send you back a copy of your approved Certificate of Organization (at no extra charge). If you file by mail, the state charges $40 for a copy of your approved Certificate of Organization. The instructions on this page are for the online filing only. Having said that, if you are not very “tech comfortable” and prefer to file by mail, you can follow this lesson instead.

Filing your LLC documents online:

Get Started:
In the left navigation, click “Business Formation (Domestic / Connecticut)”.

Important: A “Special Instructions” popup message will appear. Please read through it carefully. Your LLC’s Registered Agent will be sent an important email from the state and they must click the “acceptance link” within 48 hours, or your LLC filing will be rejected.

If you or someone you know is going to be your LLC’s Registered Agent, simply monitor your/their email address which you’ll enter in a few steps ahead. Remember, if an individual will be your LLC’s Registered Agent, they must be a resident of Connecticut.

If you hired a Commercial Registered Agent, please ask them which email address of theirs they’d like entered and tell them to keep an eye out for the email from the state.

Once you understand, you’ll need to agree to the terms by clicking the “Continue” button.

Check LLC Name Availability:

In the drop down list, select “Domestic Limited Liability Company”. In the “Business Name” box, enter your Connecticut LLC name exactly as you would like it, including your preferred capitalization, as well as the designator (the ending).

Remember: Connecticut law allows for the following designators:

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

Tips: If you’re not sure which designator to choose, “LLC” is the easiest and most common. You can can use a comma in your LLC name, or you can leave it out. For example, “JJ Construction Team LLC” and “JJ Construction Team, LLC” are both acceptable.

Do you have business name reservation number?
If you have already filed an LLC name reservation, select “yes”. Most filers don’t have one and just select “no”. Note: it’s not a requirement to file a name reservation when forming an LLC.

Click the “Continue” button to proceed.

Business Formation:

Business Email Address:
Enter your email address here. The state will use this address to send your LLC approval. It doesn’t have to be an actual “business email” address. Most filers just use a personal email address.

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, an office address, or your Registered Agent’s address (if they let you). This address can be in Connecticut, but it doesn’t have to be.

Mailing Address:
If your mailing address and principal office address are the same, check the box to the right of “Mailing Address”. PO boxes are allowed here if needed. This address can also be located in any state.

Agent Information:

• If you or a friend or family member are your LLC’s Registered Agent:
– select “Individual” in the “Agent Type” drop down list
– enter your/their name in the “Agent Name” box
– complete all the address fields (I know, there’s a lot!)
– enter their email address

• If you hired a Commercial Registered Agent:
– select “Business” in the “Agent Type” drop down list
– enter their company name in the “Business Name” box
– complete all the address fields
– enter their email address

Note: if you hired a Commercial Registered Agent, please call or email them to get all of their proper contact information.

Organizer Information:
The LLC Organizer is the person who is submitting the filing to the Secretary of State. This will most likely be you. Enter your first and last name, and then click “Continue” to proceed.

Principals (members or managers):

Click “Add Principals” to add either your LLC’s members and/or managers.

– in the “Principal Type” drop down list, select “Individual”
– enter their first and last name
– for “Title”, enter “Member” or “Manager” (learn the difference here)
– complete the address fields
– click “Continue” to save the information

• If you’d like to add more members or managers, click “Add Principals”.
• If you’re finished, click “Continue” to proceed.


Review all of the information you entered. Check for accuracy and look for any typos.

If you need to change anything, click the pencil icons to make edits.

If everything looks good, click the “Continue” button to proceed.


Enter your credit card information and your billing address (the one associated with your card).

Note: the state does not accept debit cards.

Then click the “Pay Securely using Credit Card” button.

Congratulations, your Connecticut LLC has been filed for processing!

Now you just need to wait for approval :)

Connecticut LLC Approval

The Secretary of State will process and approve your Connecticut LLC in 2 to 3 business days.

Once your LLC is approved, they will email you a copy of your approved Certificate of Organization. They will also email you back an Acceptance Letter. Sometimes they arrive in the same email, or sometimes you will receive 2 separate emails.

Your Acceptance Letter will contain your Connecticut Business ID Number. Your Business ID Number is a unique number that identifies your LLC with the Secretary of State.

Next Step

Once you file your Certificate of Organization, and it is approved by the state, you can then proceed to the next lesson: Operating Agreement.

    Dear Matt,
    Hello. What a wonderfully informative and helpful website you’ve created!!! I am hoping that you may be able to help me with something. My husband and I let our LLC (which we created in 2004) become inactive…now we would like to reactivate it…. is that something we can do online? We live in CT. Many thanks for your help!!!
    Yours, Maureen

    • Matt Horwitz March 10, 2018

      Hi Maureen, thanks so much!! Glad you’ve found us helpful :) You can file what’s called an LLC Reinstatement. In Connecticut though, you cannot do this online. You actually need to call the state and request a “Reinstatement Packet” be sent to you. You can call them during the week at 860-509-6003. You’ll have to pay any outstanding penalties and also file a current Annual Report in addition to the other forms for LLC Reinstatement.

    Hi Matt, this is a great site, thank you. Question, are there any other documents I need to file for an e-commerce store? I’m assuming I have to file something federally too, right? I’m debating whether I need to hire an attorney to do this or not. You made the CT portion seem easy.


    • Matt Horwitz June 17, 2018

      Hi Christine, you’re very welcome! Federally, you’ll get an EIN for your LLC and then file your taxes each year. You can file the LLC yourself, but we recommend working with an accountant for taxes. Taxes are usually filed and/or paid on 3 levels: federal, state, and local. Hope that helps!

    I formed an LLC in CT for my consulting business. I am moving to VA, can I still operate under the CT LLC? Do I need a member to be a resident of CT?


    • Matt Horwitz June 18, 2018

      Hi Paul, how long will you be living in Virginia for and running the business from there? You can still operate the Connecticut LLC without being a resident of Connecticut, however, if you’re doing business in Virginia, you should either 1.) register your Connecticut LLC as a Foreign LLC in Virginia (keeps EIN and bank account), 2.) dissolve Connecticut LLC and form a Virginia LLC (needs new and new bank account), or 3.) merge/redomesticate, which is moving the jurisdiction of the LLC if the states allow it (keeps EIN and bank account). Hope that helps.

    I found this very helpful when doing my process for the LLC.

    I just wanted to ask you a question. If the name of my company is July LLC, but i will be doing business as July, do i need a trade name? it will be for marketing purposes and since is an e-commerce do i need my website to have the llc

    • Matt Horwitz August 12, 2018

      Hi Valeria! If your LLC name is “July LLC”, but you want to do business as “July”, then yes, you’ll need to file a Trade Name owned by your LLC. Your website address and logo don’t have to include the LLC name. Hope that helps.

  5. Nicholas October 23, 2018

    Thank you much for putting together this highly resourceful and precious website.

    I currently live in New City, NY, and Stamford, CT but I’m setting up my warehouse and office in Philadephia, PA where I’m actively considering relocating to in the Spring of 2019.

    However, I still have a Connecticut Driver License that I don’t to change to another State yet until I make sure my new business survives in PA.

    Considering the above scenario, should I form an LLC in Pennsylvania or Connecticut? New York is definitely out of consideration.

    Thank you.

    • Matt Horwitz November 22, 2018

      Hey Nicholas, you’re welcome! I’d consider just forming the LLC in Pennsylvania since that is ultimately where you will end up doing business. If you need a Foreign LLC registration in Connecticut, you could always file one and then cancel/withdrawal when you move from Connecticut. Hope that helps.

  6. Nicholas December 22, 2018

    Yes, it helped. I thought as much myself. Thank you so much.

    • Matt Horwitz January 6, 2019

      You’re welcome Nicholas :)
