How to Form an LLC in Connecticut

Forming an LLC in Connecticut is easy

To start an LLC in Connecticut you will need to file a Certificate of Organization with the Connecticut Secretary of State, which costs $120. You can apply online, by mail, or in-person. The Certificate of Organization is the legal document that officially creates your Connecticut Limited Liability Company.

Follow the step-by-step guide below to start your Connecticut LLC today and get your business up and running.

STEP 1: Name your Connecticut LLC

Choosing a company name is the first and most important step of forming an LLC in Connecticut. Be sure to choose a name that complies with Connecticut naming requirements and is easily searchable by potential clients.

1. Follow the naming guidelines:

• Your name must include the phrase “limited liability company” or one of its abbreviations (LLC or L.L.C.).
• Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
• Restricted words (e.g. Bank, Attorney, University) may require additional paperwork and a licensed individual, such as a doctor or lawyer, to be part of your LLC.
• Your name must be distinguishable from any other Connecticut limited liability company, corporation, limited liability partnership, or limited partnership.

2. Is the name available in Connecticut? Make sure the name you want isn't already taken by doing a Business Registry Search on the Connecticut Secretary of State's website.

3. Is the URL available? We recommend that you check online to see if your business name is available as a web domain. Even if you don't plan to create a business website today, you may want to buy the URL in order to prevent others from acquiring it.

After registering a domain name, consider setting up a professional email account (@yourcompany.com). Google's G Suite offers a business email service that comes with other useful tools, including word processing, spreadsheets, and more. Try it for free

STEP 2: Choose a Registered Agent in Connecticut

You are required to nominate a registered agent for your Connecticut LLC.

What is a registered agent? A registered agent is an individual or business entity responsible for receiving important tax forms, legal documents, notice of lawsuits, and official government correspondence on behalf of your business. Think of your registered agent as your business's point of contact with the state.

Who can be a registered agent? A registered agent must be a resident of Connecticut or a corporation, such as a registered agent service, authorized to transact business in Connecticut. You may elect an individual within the company including yourself.

STEP 3: File the Connecticut LLC Certificate of Organization

To register your Connecticut LLC, you will need to file the Certificate of Organization with the Secretary of State. You can apply online, by mail, or in-person. Some states refer to the Certificate of Organization as the Articles of Organization or Certificate of Formation.

The Certificate of Organization for an LLC (limited liability company) in Connecticut is a legal document to officially form your business. You’ll be expected to provide the name of your LLC, choose a registered agent, list the services your LLC will offer, and pay the state filing fee. After you file the Certificate of Organization, we recommend you obtain an Employer Identification Number (EIN) if you plan to hire employees and open a business bank account. 

When filing your Certificate of Organization, you will need to state whether your Connecticut LLC will be member-managed or manager-managed. Before you file, read our member-managed vs manager-managed guide to help you choose the best management structure for your LLC.

If you’re expanding your existing LLC to the State of Connecticut, you will need to form a Foreign LLC.

STEP 4: Create a Connecticut LLC Operating Agreement

An operating agreement is not required for a Connecticut LLC, but it's a good practice to have one.

What is an operating agreement? An operating agreement is a legal document outlining the ownership and operating procedures of an LLC.

Why are operating agreements important? A comprehensive operating agreement ensures that all business owners are on the same page and reduces the risk of future conflict.

For more information on operating agreements, read our Connecticut LLC operating agreement guide.

STEP 5: Get a Connecticut LLC EIN

What is an EIN? EIN stands for Employer Identification Number. EINs are a nine-digit number assigned by the Internal Revenue Service (IRS) to help identify businesses for tax purposes. It is essentially a Social Security number for a business.

An EIN is sometimes referred to as a Federal Employer Identification Number (FEIN) or Federal Tax Identification Number (FTIN).

Why do I need an EIN? An EIN is required to:

• Open a business bank account
• File and manage Federal and State Taxes
• Hire employees

What if I already have an EIN for my sole proprietorship? The IRS requires that sole proprietorships get a new EIN when converting to an LLC.

Where do I get an EIN? You can get an EIN for free from the IRS. Getting an EIN is an easy process that can be done online or by mail.

FOR INTERNATIONAL EIN APPLICANTS: You do not need a SSN to get an EIN. For more information, read our How to Get an EIN as a Foreign Person guide.

Protect Your Business & Personal Assets

Get a Business Bank Account & Credit Card

Using dedicated business banking and credit accounts is essential for personal asset protection.

When your personal and business accounts are mixed, your personal assets (your home, car, and other valuables) are at risk in the event your Connecticut LLC is sued. In business law, this is referred to as piercing your corporate veil.

Additionally, learning how to build business credit can help you get credit cards and other financing in your business's name (instead of yours), better interest rates, higher lines of credit, and more.

You can protect your business with these two steps:

1. Opening a business bank account:

• Separates your personal assets from your company's assets, which is necessary for personal asset protection.
• Makes accounting and tax filing easier.

2. Getting a business credit card:

• Helps you separate personal and business expenses.
• Builds your company's credit history, which can be useful to raise capital later on.

Get Insurance For Your Connecticut LLC

Business insurance helps you manage risks and focus on growing your business. The most common types of business insurance are:

• General Liability Insurance: A broad insurance policy that protects your business from lawsuits. Most small businesses get general liability insurance.
• Professional Liability Insurance: A business insurance for professional service providers (consultants, accountants, etc.) that covers claims of malpractice and other business errors.
• Workers' Compensation Insurance: A type of insurance that provides coverage for employees’ job-related illnesses, injuries, or deaths. In Connecticut, businesses with one or more employees, excluding officers and LLC members, are required by law to have workers' compensation insurance.

Properly Sign Legal Documents

Improperly signing a document as yourself and not as a representative of the business can leave you open to personal liability. When signing legal documents on behalf of your company, you could follow this formula to avoid problems:

1. Formal name of your business
2. Your signature
3. Your name
4. Your position in the business as its authorized representative

See the image below for an example.

This ensures that you are signing on behalf of your LLC and not as yourself.

Keep Your Company Compliant

Connecticut Permits & Licenses

To operate your Connecticut LLC you must comply with federal, state, and local government regulations. For example, restaurants likely need health permits, building permits, signage permits, etc.

The details of business licenses and permits vary from state to state. Make sure you read carefully. Don't be surprised if there are short classes required as well.

Fees for business licenses and permits will vary depending on what sort of license you are seeking to obtain.

This certificate allows a business to collect sales tax on taxable sales.

Read our sales tax guide to find out more.

Connecticut Employer Taxes

Federal LLC Tax Requirements

File Your Connecticut LLC Annual Report

Connecticut requires LLCs to file an annual report with the Connecticut Secretary of State.

Avoid Automatic Dissolution

LLCs may face fines and even automatic dissolution when they miss one or more state filings. When this happens, LLC owners risk loss of limited liability protection. A quality registered agent service can help prevent this outcome by notifying you of upcoming filing deadlines and by submitting reports on your behalf.

Make Running Your Business Easier

Accounting For Your Connecticut LLC

It’s critical to get your books in order, even if you haven’t officially opened for business. A well-managed accounting system will help you:

• Track your business finances, including bills, expenses, and income.

Interfacing with Clients and Customers

You can get a dedicated business mailing address and a business phone number with call-forwarding so that you never need to worry about losing a potential customer.
