    4 Steps to Register Your Business Name in Maine

    Getting your business name officially registered in Maine is essential for establishing your entrepreneurial presence in the state. Here are four simple steps to guide you through the registration process:

    Step 1: Choose Your Business Structure in Maine

    When starting a business in Maine, it’s crucial to determine the appropriate business structure based on your business’s nature and growth goals. There are several options to choose from, each with its own requirements. It’s important to note that only certain business structures require registration with the Maine Secretary of State, especially those that involve incorporation.

    Sole Proprietorship

    A sole proprietorship is the simplest business structure in Maine, where the owner and the business are considered one legal entity. The owner is personally responsible for the business’s debts and liabilities. Establishing a sole proprietorship is relatively straightforward, with limited legal and administrative requirements. Unlike other structures, a sole proprietorship does not need to be registered with the state, but local permits or licenses may be necessary.

    General Partnership

    In a general partnership, two or more individuals share ownership, profits, and losses. Each partner is personally liable for the business’s debts and legal obligations. While a general partnership doesn’t require registration with the state, you might need to file a “Maine Assumed Name Certificate” (DBA) in the county where your business is located.

    Limited Partnership (LP)

    A limited partnership in Maine consists of one or more general partners with unlimited personal liability and one or more limited partners who have limited liability. To establish an LP, you’ll need to file a “Certificate of Limited Partnership” with the Maine Secretary of State.

    Limited Liability Company (LLC)

    An LLC offers the benefits of limited liability protection, similar to a corporation, and the tax advantages and simplicity of a partnership. To set up an LLC in Maine, you must file a “Certificate of Formation” with the Maine Secretary of State and create an Operating Agreement that outlines the company’s management and ownership structure.


    A corporation is a distinct legal entity from its shareholders, providing limited liability protection. There are two types of corporations in Maine: C-corporations and S-corporations. Establishing a corporation requires filing “Articles of Incorporation” with the Maine Secretary of State. Corporations have more formalities, including creating bylaws, issuing stock, and conducting regular board and shareholder meetings.

    When deciding on a business structure in Maine, carefully consider factors like liability protection, taxation, and management requirements. If you need assistance in making this decision, it’s advisable to consult with a legal or business professional.

    By following these steps and selecting the appropriate business structure, you can ensure a smooth registration process for your business name in Maine.

    Step 2: Select a Unique Business Name in Maine

    When starting a business in Maine, the second essential step is selecting a unique and fitting name for your enterprise. There are several avenues available for naming your business, each with its own considerations and regulations. It’s crucial to understand the naming rules specific to Maine to ensure a smooth registration process and protect your brand identity.

    In Maine, you have three options for naming your business:

    Registering a legal entity name is mandatory for businesses in Maine. This name serves as the official identification of your company in the state. It’s important to choose a unique entity name to avoid potential conflicts with other businesses. Maine’s naming laws also require the inclusion of appropriate company suffixes (e.g., LLC, LP, or Corp) that reflect the type of business you’re registering. To check name availability, you can use the Maine Secretary of State’s database.


    Obtaining a trademark provides intellectual property protection for your business name or logo on a national level. Conducting a thorough search in the USPTO database is essential to ensure your desired name or logo isn’t already registered. Registering a trademark grants exclusivity and prevents others from using a similar name or logo for similar goods or services across the United States. However, it’s important to note that trademark registration does not automatically grant the right to use the name or logo in all circumstances.

    Doing Business As (DBA)

    A Doing Business As (DBA) name allows you to operate your business under an official name that’s different from the legal entity name. To establish a DBA, you must file a Certificate of Assumed Name with the county clerk’s office where your business is located. Unlike legal entity names, DBAs are not required to be unique at the state level, but they’re subject to federal trademark laws.

    While you have the option to pursue all three naming routes to ensure the exclusivity and protection of your business name, you can also choose a single option that best suits your needs. It’s recommended to use the same name for all registration methods to maintain consistency and clarity for your customers.

    By understanding and considering these naming options, you can successfully register your business name in Maine and establish a strong brand identity for your enterprise.

    Step 3: Check Business Name Availability in Maine

    Before proceeding to register your business, it’s essential to ensure that the name you wish to use is available and not already in use by another entity. To perform a thorough business name availability search in Maine, follow these three steps:

    The first thing you should do is conduct a federal trademark search to check if your desired business name has already been trademarked. Federal trademarks take precedence over state-level registrations, so it’s crucial to verify that your preferred name isn’t already protected by a trademark. 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 Maine. Utilize the Maine Corporate Name Search tool to search for registered business names within the state. Ensure that your exact business name is available, and also check for any significantly similar business names that might cause confusion.

    In addition to checking trademark and state-level availability, consider doing a domain search to determine if the .com version of your business name is available. Although not every business may require a website, securing the .com domain can be valuable for branding and online presence. Make sure the desired domain name isn’t already taken or reserved by another entity.

    By registering the .com version of your business name with ZenBusiness, you secure exclusive rights to the website name, safeguarding your brand from potential misuse at an affordable price.

    By conducting these three searches, you can confidently proceed with registering your business name, knowing that it’s both legally and practically available for use in Maine.

    Step 4: Form Your Business With the State of Maine

    Once you have decided on your business structure and name, the next crucial step is to formally register your business with the State of Maine.

    For a Maine LLC, you will need to submit the Certificate of Formation to the Maine Secretary of State. This can be done via mail. On the other hand, for a Maine corporation, you’ll need to file the Articles of Incorporation with the Maine Articles of Incorporation.

    Protect Your Business Name With a Trademark

    After confirming the availability and securing your business name, you have the option to apply for a trademark for your business. This process typically costs around $225 to $400, with additional attorney fees, as well as a renewal fee every 10 years.

    Although this might be a significant cost for startups or small businesses, having a trademark provides nationwide protection under federal law. It grants you legal protection if others attempt to use a similar name, giving your brand a strong defense. However, for most local businesses, this step may not be necessary unless they plan to expand nationally.

    How to File a Maine Fictitious Name – DBA?

    To file a Maine Fictitious Name (DBA), follow these simple steps:

    1. Choose a Name: Select a unique and available name that you want to use for your business. Ensure it doesn’t conflict with any existing registered business names in Maine.
    1. Conduct a Name Search: Verify the availability of your chosen name by conducting a name search through the Maine Secretary of State’s website or by contacting their office directly.
    1. Complete the Application: Download and complete the Maine Fictitious Name Registration form, providing your chosen name and relevant business information.
    1. Notarize the Form: Have the completed form notarized by a notary public to validate the authenticity of your application.
    1. Submit the Application: Send the notarized form along with the filing fee to the Maine Secretary of State’s office either by mail or in person.
    1. Publication (Optional): In some cases, you may need to publish a notice of your fictitious name in a local newspaper as required by Maine law. Check with the Secretary of State’s office to see if this step applies to your situation.
    1. Receive Confirmation: Once your application is approved, you will receive a certificate confirming your registered fictitious name. Keep this certificate for your records.

    By following these steps, you will have successfully filed your Maine Fictitious Name (DBA), allowing you to operate your business under the chosen name while keeping your legal entity intact.

    How to Change the Name of a Maine Business?

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

    1. Filing for a Fictitious Name (DBA Name):

    This method is the easiest way to operate your business under a different name without altering its legal name. Sole proprietorships and general partnerships can use a DBA name to have a separate business name. For LLCs and corporations, this option allows them to operate with brand names that do not require the necessary LLC or Inc. suffix used in their legal names, simplifying business operations.

    1. Filing an Amendment to the Legal Name:

    If you want to change the legal name of your LLC or corporation, this is a suitable option. You can file either the Certificate of Amendment for LLCs or the Articles of Amendment for corporations by mail to the Maine Secretary of State, along with a $50 filing fee.

    • Business Name Search: Before registering a business name in Maine, it’s essential to conduct a thorough search to ensure the desired name is available and not already in use by another business entity. You can search for existing business names on the Maine Secretary of State’s website or contact their office for assistance.
    • Business Entity Types: Maine offers several business entity types, including sole proprietorships, partnerships, Limited Liability Companies (LLCs), corporations, and more. Each entity type may have specific requirements for naming conventions.
    • Uniqueness Requirement: The chosen business name must be unique and distinguishable from the names of existing businesses in Maine. It should not be confusingly similar to any other business names already registered.
    • Restricted Words: Some words may be restricted or prohibited for use in business names, such as terms that could mislead the public or imply governmental affiliation. The Secretary of State’s office can provide a list of restricted words.
    • Fictitious Name (Doing Business As – DBA): If you plan to operate your business under a name different from your legal business name (for sole proprietors or partnerships), you may need to register a “Fictitious Name” or “Doing Business As” (DBA) with the Secretary of State.

    • Trademark Consideration: Registering a business name with the Secretary of State does not provide trademark protection. If you wish to protect your business name at the federal level, you may want to consider filing a trademark application with the United States Patent and Trademark Office (USPTO).
