Connecticut LLC Filing on Business.CT.gov
A Connecticut LLC is created by filing a Certificate of Organization with the Secretary of the State, and the online route starts at Business.CT.gov. This page covers the account the site requires, the certificate section by section, the reasons filings are rejected, how to check on one and the annual report that follows on the same site. Or we prepare the certificate and file it on Business.CT.gov for you.

Form Your Connecticut LLCWhat Business.CT.gov Is
Business.CT.gov is where the Connecticut Secretary of the State's Business Services Division takes most business filings online. A Certificate of Organization started there opens in the state's filing system at service.ct.gov once you are signed in, and the same account is where the annual report is filed each year. The Secretary of the State's paper certificate, revised July 2024, notes that it can be filed online at business.ct.gov, and the state's own guidance says online filing means faster processing and fewer rejections.
Connecticut's certificate asks more of the owners than most states' forms do. At least one member or manager is listed with a title, a business address and a residence address. The registered agent signs to accept the appointment. And the company gives a six-digit NAICS code and an email address, or checks a box saying it has none. Only three members or managers are displayed on the business registry page, but every name filed is part of the record, available in a copy of the original filing.
We prepare Connecticut certificate of organization filings and submit them through Business.CT.gov for customers, the way an accountant or attorney would. Connecticut's fee is the same whether you file on Business.CT.gov yourself or we file for you; this page explains both routes so you can pick one.

Before You Start on Business.CT.gov
- A Business.CT.gov account. The state says you must be logged in, or create an account, to file online. Keep the login with the company's records; the annual report is filed under it.
- The agent's acceptance. On the paper certificate the agent signs a line accepting the appointment, and for a business agent the person signing also prints a name and title. The state's instructions do not describe how the online filing records the acceptance, so have the agent's agreement in writing before you start.
- A residence address for at least one member or manager. Connecticut asks for each listed person's business address, or none, and residence address, and neither can be a post office box.
- A NAICS code and an email. The six-digit industry code is required, and the entity email is where the Secretary of the State sends the annual report reminder. A company with no email checks the none box rather than leaving the line blank.
The Business.CT.gov LLC Filing, Step by Step
Step 1: Sign in to Business.CT.gov and start the Certificate of Organization
Sign in to your Business.CT.gov account, or create one, and start a Certificate of Organization for a domestic limited liability company. The filing continues in the state's service.ct.gov filing system.
Step 2: Enter the name (section 1)
The name must include a business designation such as Limited Liability Company, LLC, L.L.C., Limited Liability Co., Ltd. Liability Company or Ltd. Liability Co., and be distinguishable from every active business name on record. A professional LLC uses P.L.L.C., PLLC or Professional Limited Liability Company.
Step 3: Give the principal office and mailing address (sections 2 and 3)
A full street address for the principal office, never a post office box, and a mailing address, which is required and can be a post office box.
Step 4: Appoint the registered agent (section 4)
Either an individual who lives in Connecticut, including a member or manager, with a business address or none, a Connecticut residence address and a Connecticut mailing address; or a business already on record with the Secretary of the State with a Connecticut address. The LLC cannot be its own agent, and the agent signs accepting the appointment. If you choose our registered agent service, our agent is appointed here.
Step 5: List at least one member or manager (section 5)
Full name, title (member, manager or managing member), business address or none, and residence address, with no post office box for either. Add as many as you like; only three are displayed on the business registry page.
Step 6: Give the entity email and NAICS code (sections 6 and 7)
The company's email, where annual report notices go, or the none box checked, and a six-digit NAICS code for the business.
Step 7: Sign as organizer (section 8)
The organizer prints a full name and signs under the penalties of false statement. The LLC cannot be its own organizer, a member or manager can be, and a business entity can be if the person signing for it gives a name and title; when we file, that is how we sign.
Step 8: Pay the state and submit
Pay Connecticut's fee by Mastercard, Visa, Discover or American Express and submit. Connecticut's 24-hour expedite is available only for online filings and is charged on top of the fee; the amount is in the facts box on our Connecticut LLC page.

A rejection costs the days the filing sat in the queue, and in some states the name you wanted. Our name check and field review happen before the filing goes to Business.CT.gov, which is most of what you pay us for.
Processing and Checking Status
The Secretary of the State's guidance says online filing brings faster processing and fewer rejections than paper, and gives no fixed turnaround. We do not promise one either; when we file, we watch the filing and send you the approved certificate the day it comes back.
For a faster review, Connecticut sells 24-hour expedited service, available only for online filings and charged on top of the filing fee. The amount is in the facts box on our Connecticut LLC page.
To check on a filing, sign in to your Business.CT.gov account, or search the company name in the Secretary of the State's business records search once it is filed. On a paper filing, the confirmation goes to the filing party named on the form.
Official pages: Business.CT.gov · Domestic LLC forms and fees (business.ct.gov).
The speed we control is when the filing reaches Connecticut: same-day LLC filing sends it to Business.CT.gov the business day your details are in.
After Approval on Business.CT.gov
- The annual report. Every Connecticut LLC files an annual report between January 1 and March 31, starting the year after it is formed, online at Business.CT.gov, and the Secretary of the State emails the company when it is due. As a state fact, Connecticut adds no late fee to an LLC's report, but prior years have to be filed before the current one, and an LLC that stops filing is dissolved.
- Taxes. The certificate's instructions send new companies to the Department of Revenue Services, at portal.ct.gov/drs, for any tax liability, and the company registers there before any taxable activity.
- Changes and closing. Later changes are filed through Business.CT.gov as well, and the form reminds owners that a Certificate of Dissolution is required to close the company. Connecticut has no newspaper publication requirement for LLCs.

Filing It Yourself vs Having Us File It

| When it is submitted | Whenever you sit down to finish the form. | Standard orders go to Connecticut within 3 business days; same-day submission by 2 PM Eastern goes in that business day. |
| Who answers questions | The Connecticut Secretary of the State's help pages and phone line. | A person on our team, by email, Monday to Friday. |
| The state fee | Paid to Connecticut on Business.CT.gov. | Paid to Connecticut, the same amount, itemized before you pay. |
Business.CT.gov LLC Filing Questions
Can I file a Connecticut LLC myself on Business.CT.gov?+
Yes. Sign in or create an account, complete the Certificate of Organization and pay Connecticut's fee by card; the fee is the same whether you file or we do. You take on the name check, the agent's signed acceptance, a residence address for at least one member or manager, the NAICS code and watching for a rejection. When we file, each of those is checked before the filing goes in.
Do I need a Business.CT.gov account?+
Yes. The state says you must be logged in, or create an account, to file online, and the same account is where the annual report is filed each year. Paper filing is still possible for anyone who prefers it, by mail to the Business Services Division in Hartford.
Does the registered agent sign in Connecticut?+
Yes. Connecticut's certificate has a line where the agent signs accepting the appointment, and a business agent's signer also prints a name and title. The state's instructions do not spell out how the online filing captures that acceptance, so we treat the agent's written agreement as a requirement either way. An individual agent must live in Connecticut; a member or manager can serve.
Why does Connecticut ask for a residence address?+
The certificate requires at least one member or manager with a name, title, business address (or none) and residence address, and neither address can be a post office box. Only three members or managers are displayed on the business registry page, but every address on the certificate is part of the filed record. Owners who want fewer details out there list the one person the form requires.
How long does Connecticut take?+
Connecticut gives no fixed turnaround, and says only that online filing is faster and draws fewer rejections than paper. We do not promise the state's time. If the review itself needs to be faster, Connecticut sells 24-hour expedited service for online filings. Expedited LLC filing by state
When is the Connecticut annual report due?+
Between January 1 and March 31 every year, starting the year after the company is formed, filed online at Business.CT.gov. The Secretary of the State emails the company at the address on the certificate when it is due, which is one reason the email line matters. File the Connecticut annual report
What is the NAICS code on the Connecticut certificate?+
A six-digit North American Industry Classification System code that describes the business. Connecticut requires one on the Certificate of Organization; the certificate's instructions point to census.gov/naics to look it up. Pick the code closest to what the company actually does.
Is America LLC Filing part of Business.CT.gov or the Secretary of the State?+
No. Business.CT.gov and the filing system behind it belong to the State of Connecticut, and the Secretary of the State's Business Services Division files Connecticut LLCs. America LLC Filing is a private company. We prepare your Certificate of Organization and submit it through Business.CT.gov for you, and our fee is for that work, separate from the state's own fee.
