How to Start an LLC in Connecticut

If you plan on starting a business in Connecticut, consider forming an LLC. LLCs provide liability protection, flexible management structure and multiple tax options for their owners.

To get started, you’ll need to submit Certificate of Organization to the Connecticut Secretary of State and pay a $120 state filing fee. Follow this guide to set up your Connecticut LLC.


1. Name Your LLC

First and foremost, decide the name of your LLC. Connecticut has some rules you’ll need to follow to make sure your name is valid (those rules are covered in CT Gen Stat § 34-243k.) Basically, you need to know the following things when choosing the name of your Connecticut LLC:

  • Your name needs to be available to use in Connecticut
  • Your name must contain the phrase or abbreviations: “limited liability company,” “LLC,” or “L.L.C.
  • Your name can’t include any words or abbreviations that suggest a different entity type, such as “Incorporated,” “Corp,” or “Limited Partnership.”

We provide a directory of state business name availability guides you can use to check if your LLC name is available for use in Connecticut.

Tip: Connecticut LLC names can be reserved for up to 120 days by submitting an Application of Reservation of Business Name to the Connecticut Secretary of State along with a $60 fee.

2. Register Your Domain Name

The next thing you’ll want to do is get a domain name for your business website. A domain name is sort of like a street address for your website: it’s the way people find your business online. Ideally, your business domain name should match or otherwise make a clear connection to your business name or what the business does.

There are several benefits to registering your domain early:

  • Credibility: A professional domain name demonstrates your commitment to crafting an online presence that potential customers connect to and trust.
  • Consistency: When your domain name resonates with your business name, you reinforce your business brand, which aids customer recognition in remembering your business.

Another benefit of getting a domain name? You get access to a professional business email address. This email is available even before you put your business website together.

Tip: We provide a free year of domain registration and business email when you hire us to help you form your business.

3. File LLC Certificate of Organization

For the third step in creating your Connecticut LLC, you’ll need to submit a Certificate of Organization to the Secretary of State online, by mail, or in person. This officially forms your LLC with the state. Here’s what the form asks for.

Note: All of the information on this form will become part of the public record.

Filing Party

This is the person who fills out your Certificate of Organization and submits it to the Secretary of State.

Filing Party Mailing Address

This address is where confirmation that your documents have been processed will be delivered.This must follow the previously discussed rules for Connecticut LLC names, such as including an identifier like “LLC” or “Limited Liability Company.”

Company Name

Your company name must follow the previously discussed rules for Connecticut LLC names, such as including an identifier like “LLC” or “Limited Liability Company.”

Principal Address

The principal address for your LLC must be a physical street address.

Mailing Address

P.O. boxes are allowed for a mailing address.

Registered Agent Information

A registered agent accepts service of process or legal mailings on behalf of your business. In Connecticut, you can be your own registered agent or hire a registered agent like Northwest. Connecticut’s laws for registered agents are explained in CT Gen Stat § 34-243n.

Your Connecticut registered agent must:

  • Have a physical address (can’t be a P.O. box or virtual office) in Connecticut.
  • Keep regular business hours at this address.
  • Accept service of process (lawsuits and other legal mail) on behalf of your business and forward it to you.

4. Adopt an Operating Agreement

An operating agreement is an internal document that determines the way your LLC runs. It defines important information for your business, like what was contributed financially and by who, how to make important decisions, and what should be done if things don’t go as planned.

While Connecticut does establish rules for what an operating agreement can include, technically, you aren’t required to have one. However, drafting an operating agreement is a wise choice for legal protection for your LLC, and for otherwise keeping everything running at an even keel. Besides, if you don’t have one, your business will instead operate under Connecticut’s default LLC laws, and wouldn’t you rather make your own decisions about member voting rights and profit allocation?

Tip: We provide an attorney-drafted initial Connecticut operating agreement template you can use for free.

5. Get an EIN

An EIN (employer identification number) identifies your business for the Internal Revenue Service. It’s also important if you have multiple members, intend to hire employees, or open a business bank account. You can apply for an EIN for free directly from the IRS online, or use us to get an EIN for you.

Get a Business Bank Account

LLCs enjoy limited liability because they’re treated as a separate legal entity from their owners. So if you mix personal and business funds, a court might decide your LLC isn’t actually a separate entity. This is why it’s important for your LLC to have its own bank account.

When you go to the bank to open that account, make sure you’ve got these essentials with you:

  • A copy of your Connecticut LLC Certificate of Organization
  • Your LLC’s operating agreement
  • The EIN (employer identification number) for your LLC

If your LLC has more than one member, you may need to provide an LLC Resolution to Open a Bank Account.

7. File State Reports & Taxes

Connecticut LLCs are required to file an annual report every year. Filing your annual report ensures that the state has up-to-date contact information for your business, and that they know if your LLC has changed ownership. In Connecticut the filing fee for annual reports is $80.

Connecticut annual reports are due for LLCs on March 31, starting with the year after your business forms.

Tip: Worried you’ll forget? Let us file your Connecticut annual report for you.

8. File the Beneficial Ownership Information Report

As of 2024, a new federal filing is required for most Connecticut LLCs called the Beneficial Ownership Information (BOI) Report. In the BOI Report, you’ll provide some details about your company applicant and all the LLC’s beneficial owners with the Financial Crimes Enforcement Network. You can handle this filing yourself, or if you find it overly complicated, you can have us do it for you for a $9 fee.
