How to Start an LLC in Connecticut

An LLC (aka Limited Liability Company) is a hybrid business entity combining a corporation’s characteristics with a partnership or sole proprietorship. It separates your personal assets from your business assets, thus giving you personal asset protection. For an LLC, members’ personal assets are not affected by business debts. However, in some cases, if the LLC is sued for business debts, courts might pierce the corporate veil and use the owner’s personal assets to meet their corporate liabilities.

If you wish to start an LLC in Connecticut, you must file your Certificate of Organization with the State and pay a filing fee of $120. While it’s the most important step, it’s not the only one. There are 4 other crucial steps to follow to get your LLC formed in Connecticut. Below are all 5 steps that explain everything you need to do to start a Connecticut LLC in 2024. Let’s get started! You can always hire a professional LLC formation service in Connecticut to set up your LLC instead of doing it alone; a Pro service will ensure everything is done properly.

Step 1: Decide a Name for Your Connecticut LLC

The first step while forming a limited liability company in Connecticut is to give a proper name to your LLC. Before you name your business, you must know that the name should be easy to remember, available in the state, and follows all the LLC naming guidelines.

Connecticut LLC Naming Guidelines

There are a few specific requirements all the LLCs in Connecticut have to follow while naming their Company. Some of the most important requirements are as follows:

  • Your business name should be available and no other existing business in Connecticut can have the same name. ZenBusiness offers unlimited business name searches without any hassle.
  • “Limited Liability Company”, “LLC”, “L.L.C.”, “LC”, “L.C.”, and “Limited Company” – any one of these has to be used as a suffix in your business name.
  • You cannot use any name for your business that is confusing or misleading. Terms such as “Treasury”, “State Department”, “FBI”, “CIA”, etc. shouldn’t be included.

Doing Business As (DBA) or Trade Name

Once you have a legal name for your LLC, you can register it. However, it is not mandatory. You can, instead, use DBA, Fictitious Name, or Trade Name. In that case, you must register your name with the Connecticut Secretary of State by submitting Trade Name online form along with the filing fee of $10.

Apart from LLC formation, ZenBusiness offers customized website templates and business emails at a very reasonable price.

Do I have to include LLC in my company email/domain?

It is not legally mandatory to use the word LLC in your domain name or email. If you want, you can use it. However, it is recommended not to use LLC in the domain name. A domain name should be short and easy to remember.

Step 2: Assign a Registered Agent in Connecticut

The second step to forming an LLC in Connecticut is to appoint a Registered Agent. A registered agent is a person or business entity working on your LLC’s behalf. This person or business will receive important tax forms, legal documents, all notices of lawsuits, and other official government correspondence in Connection. Hence, hiring a competent Connecticut Registered Agent for your LLC is necessary.

Make sure your registered agent is a resident of Connecticut or has a physical street address. This address will be used as the principal address of your LLC to receive any legal documents. Most LLC formation companies also provide registered agent services. Below are two great LLC formation services; even if you buy their cheapest plan (normally $0), you also get registered agent service and other services at a very reasonable price.

Who Can Be a Registered Agent?

A person above 18 years of age and has a physical address in the state of Connecticut can be a Registered Agent. A Registered Agent can be an independent person or can be a business entity. One is responsible for handling all the legal documents on the LLCs behalf.

Can I Be My Own Registered Agent?

Yes, you can be your own registered agent if you are a resident of the state of Connecticut and you are above 18 years of age. To become a registered agent, you must have the authority to conduct any type of business in Connecticut.

Why Shouldn’t I be My Own Registered Agent?

There are a few reasons why you shouldn’t be your own registered agent. The address of the registered agent is used to communicate with the SOS or for any legal activities. If you are your own registered agent, you might have to upload your personal address to the public forum. Besides, the registered agent must be at the address during business hours. It won’t be easy for you as you also have to take care of other things in your LLC. Hence, it is wiser to appoint a separate entity as your registered agent.

What is Piercing the Corporate Veil in LLC?

If an LLC is sued in Connecticut, in some cases, courts might decide to lift the corporate veil, which means the owners of the LLC will be personally liable for their business debts. They might have to forgo their personal assets to repay their business debts. This is called piercing the corporate veil, where personal and business assets are not separated anymore. Your personal assets can be protected if you have enough capital and all your LLC documents are properly filed.

Registered Agent Consent Application

In Connecticut, the registered agent has to sign a consent letter (online or offline) confirming consent to being Appointed in written or electronic form. If you change your registered agent, the new one has to provide his/her consent as well. The consent part is mentioned on the Form of Change of Registered Agent.

This consent letter assures that the Registered Agent has given his nod to serve as an Agent. They can reject the appointment too by filing a Rejection of Appointment. It is important to have this letter to avoid any future discrepancy between the Registered Agent and LLC. The Change of Agent Form can be filled and submitted along with the filing fee of $150. For more information on the same, read our guide on Connecticut Registered Agent.

After Starting Your Connecticut LLC

After forming your LLC, there are still some things that you will need. The most important thing is to separate your business and personal assets. LLCs have limited liability protection that protects your personal assets from business liability. This is called a corporate veil. However, the corporate veil can be lifted or pierced by the court if the LLC is sued. In that case, the owners of the LLC become personally liable for their corporate debts. A few things like appointing a legit registered agent, having enough capital, and filing all the major documents with the state can save the LLCs from being pierced into the corporate veil.

BOI Report Filing

According to the Corporate Transparency Act, every LLC, corporation, and other type of business that is registered with the Connecticut SOS or similar authority, must file the BOI report with FinCEN. From January 1, 2024, it is mandatory to file a BOI report for every business entity. In this report, LLCs have to share information about the beneficial owners (having equal or more than 25% share). LLC owners can file BOI reports online or offline.

LLCs in Connecticut that are created before January 1, 2024, should file their BOI report by January 1, 2025. LLCs that are created in 2024, must file the BOI report within 90 business days of finishing the LLC formation process. Missing out on filing the BOI report may lead to a monetary penalty of $500/day.

Apart from that, there are a few things you need to take note of,
