    4 Steps to Register Your Business Name in Connecticut

    Registering your business name in Connecticut is a crucial step towards establishing your entrepreneurial presence in the Constitution State. To assist you with the process, here are four straightforward steps to officially register your business name in Connecticut:

    Step 1: Choose Your Business Structure in Connecticut

    When taking the important step of registering your business in Connecticut, one of the initial and crucial decisions is determining its legal structure. Your chosen structure will play a significant role in defining various aspects, such as tax responsibilities, personal liability, and management obligations.

    Sole Proprietorship

    In Connecticut, a sole proprietorship stands as the most straightforward business structure. With this option, you and your business are viewed as a single entity, leaving you personally accountable for any debts and liabilities. Setting up a sole proprietorship is relatively easy and comes with minimal legal and administrative requirements. While state registration isn’t mandatory for a sole proprietorship in Connecticut, it may be necessary to obtain local licenses or permits.

    General Partnership

    If your business is co-owned by two or more individuals sharing profits and losses, a general partnership may be suitable. Each partner bears personal liability for the business’s debts and legal commitments. Unlike sole proprietorships, general partnerships in Connecticut don’t require state registration, but filing a “Certificate of Trade Name” (also known as DBA) with the Secretary of State may be necessary.

    Limited Partnership (LP)

    In Connecticut, a limited partnership consists of one or more general partners with unlimited personal liability and one or more limited partners offering capital but having limited liability. To establish an LP in the state, filing a “Certificate of Limited Partnership” with the Secretary of State is mandatory.

    Limited Liability Company (LLC)

    The LLC structure provides a flexible option that combines liability protection akin to a corporation with the tax benefits and simplicity of a partnership. For forming an LLC in Connecticut, filing a “Certificate of Organization” with the Secretary of State and drafting an Operating Agreement outlining management and ownership details are required steps.


    A corporation is a distinct legal entity apart from its shareholders, granting limited liability protection. Connecticut recognizes two types of corporations: C-corporations and S-corporations. Creating a corporation necessitates filing a “Certificate of Incorporation” with the Secretary of State, establishing bylaws, issuing stock, and conducting regular board and shareholder meetings.

    The importance of selecting the right business structure in Connecticut cannot be overstated, as it significantly impacts your business’s success. Deliberate on the level of personal liability protection you require, the tax obligations you will face, and the management framework needed before finalizing your decision. 

    Seeking advice from legal or business professionals can prove invaluable in making this critical choice.

    Step 2: Select a Unique Business Name in Connecticut

    Selecting a name for your business goes far beyond being a mere formality – it plays a pivotal role in establishing your brand’s identity and drawing in potential customers. If you’re an entrepreneur in Connecticut, you’ll have several options to consider when naming your business, each carrying its own set of rules and requirements. 

    To ensure a smooth registration process and avoid conflicts, it’s crucial to grasp the specific guidelines for naming businesses in Connecticut.

    The first step in registering your business name in Connecticut is to choose a distinctive legal entity name. This name serves as an official identification for your company within the state and must be unique to avoid any clashes with existing businesses. 

    Connecticut has specific rules about the use of company suffixes such as LLC, LP, or Corp, which should align with the type of business you’re establishing. Before finalizing your decision, you can check the availability of your desired name by using the Connecticut Secretary of State’s SOS Direct database.


    For nationwide protection of your business name or logo, obtaining a trademark is crucial. Conducting a comprehensive search in the USPTO database is essential to ensure that your chosen name or logo isn’t already registered by someone else. Once your trademark is secured, you gain exclusive rights to use the name or logo for similar goods or services, safeguarding your brand identity from potential infringement.

    Doing Business As (DBA)

    In Connecticut, you have the option to operate your business under a different name, distinct from your official legal entity name, using a “Doing Business As” (DBA) name. This flexibility allows you to create a unique brand identity that resonates with your customers. 

    To establish a DBA name, you’ll need to file an Assumed Name Certificate (DBA) with the county clerk’s office in the location where your business operates. Unlike legal entity names, DBAs are not required to be unique at the state level, but they’re subject to federal trademark laws.

    By carefully considering these naming options and adhering to Connecticut’s regulations, you can successfully register your business name and protect your brand in the competitive market. Choosing a distinctive business name in Connecticut will set the stage for your business’s success and make a lasting impression on your customers.

    Step 3: Check Business Name Availability in Connecticut

    Before finalizing your business name and registering your company, it’s crucial to ensure that the name you desire is available for use in Connecticut. To do this, follow these three essential searches:

    The first step is to conduct a federal trademark search to determine if your chosen business name is already trademarked. Federal trademarks take precedence over state-level registrations, so it’s vital to make sure your desired name isn’t already legally protected. To perform a federal trademark search, visit the U.S. Patent and Trademark Office (USPTO) website and use their TESS Search tool.

    Once you’ve confirmed that your business name isn’t trademarked, it’s time to check its availability at the state level in Connecticut. Use the Connecticut Business Inquiry Search tool to find registered business names within the state. During your search, ensure that your exact business name is available and that there are no other companies using significantly similar names.

    In addition to the trademark and state-level searches, it’s a good idea to check the availability of the .com version of your business name. While not every business requires a website, having a matching .com domain can be advantageous for branding and online presence. Use a domain search service to see if the .com domain for your business name is available for registration.

    Registering the .com version of your business name with ZenBusiness ensures exclusive use and protection for an affordable price. By performing these three comprehensive searches, you can confirm that your desired business name is available and avoid any potential conflicts or legal issues down the road.

    Step 4: Form Your Business With the State of Connecticut

    Once you have decided on your business structure and name, the next step is to officially register your business with the state of Connecticut. This process will give your business legal recognition within the state.

    • For a Connecticut LLC:

    To register your Connecticut Limited Liability Company (LLC), you will need to submit the “Certificate of Organization” to the Connecticut Secretary of the State. This can be done either online or through the mail.

    • For a Connecticut corporation:

    If you’re forming a corporation in Connecticut, you must file the “Certificate of Incorporation” with the Connecticut Secretary of State.

    Protect Your Business Name With a Trademark

    After confirming the availability of your business name and securing it, you may consider applying for a trademark for your business. This step is optional but can provide valuable nationwide brand protection under federal law. It can be particularly helpful if you plan to operate on a national scale and want legal precedence in case of any conflicts with similar business names.

    Keep in mind that obtaining a trademark can be costly, usually ranging from $225 to $400, in addition to attorney fees. Additionally, you will need to renew the trademark every 10 years. While this level of protection can be advantageous for established businesses or those with national ambitions, it may not be necessary for smaller businesses focusing on local operations.

    How to File a Connecticut Fictitious Name – DBA?

    To file a Connecticut Fictitious Name, also known as a “Doing Business As” (DBA) name, follow these steps:

    1. Choose a unique business name
    2. Check if the name is available by searching the state’s business name database
    3. Obtain and complete the “Trade Name Registration” form
    4. Notarize the form if required by your town
    5. File the form online or by mail with the Connecticut Secretary of State
    6. Pay the filing fee
    7. Display the DBA certificate at your business location
    8. Renew the registration every five years if needed

    Remember, the purpose of registering a fictitious name is to conduct business under a different name than your legal business name. It does not create a separate legal entity like an LLC or corporation would.

    How to Change the Name of a Connecticut Business?

    If you wish to change the name of your business in Connecticut, there are two methods to do so:

    • Filing for a Trade Name (DBA Name):

    For sole proprietorships and general partnerships looking to operate under a different name without altering their legal name, filing for a Trade Name (also known as “Doing Business As” or DBA) is the simplest option. It enables you to use an alternative business name without the need for a formal name change.

    • Submitting an Amendment to the Legal Name:

    If you have an LLC or corporation and want to change its legal name, filing an amendment is the appropriate course of action. This involves updating the legal name of your existing business entity.

    To initiate this process, you can find the necessary forms for both options online:

    • Certificate of Amendment for LLCs
    • Certificate of Amendment for Corporations

    Once you have the appropriate form, you must file the Certificate of Amendment online and pay a filing fee of $25. This will facilitate the name change for your business in Connecticut.

    Business Name Registration Laws in Connecticut

    Business Name Registration Laws in Connecticut for Limited Liability Companies (LLCs) are as follows:

    • Business Structure: Before registering a business name, you must decide on the legal structure of your business. Common options include sole proprietorship, partnership, Limited Liability Company (LLC), corporation, etc.
    • Name Availability: To ensure that your chosen business name is available and distinguishable from existing names, you should conduct a name search with the Connecticut Secretary of State’s office. This step is essential to avoid any potential trademark conflicts and legal issues.
    • Trade Names: In Connecticut, a trade name, also known as a “doing business as” (DBA) name, is an assumed name that a business uses instead of its legal name. If you’re operating your business under a name other than your legal business name, you will likely need to register the trade name with the town clerk’s office in the town where your business is located.
    • Business Entity Registration: If you’re forming a new legal business entity (LLC, corporation, etc.), you will need to register with the Connecticut Secretary of State’s office. During the registration process, you will typically need to provide your chosen business name, the nature of your business, the names of the owners or members, and other relevant information.
    • Trademarks: Registering a business name with the Secretary of State does not provide trademark protection. If you want exclusive rights to use the business name statewide and beyond, you should consider registering it as a trademark with the United States Patent and Trademark Office (USPTO).
    • Renewals: Business name registrations and trade name registrations may have specific renewal requirements. Be sure to stay informed about any renewals or changes to keep your registration in good standing.

    Remember, business laws can change over time, so always check with the Connecticut state government or seek legal advice for the most up-to-date and accurate information about business name registration in Connecticut.
