    4 Steps to Register Your Business Name in Indiana

    Registering your business name in Indiana is an essential milestone on your path to success in Hoosier State. Follow these four simple steps to officially register your business name in Indiana and embark on your entrepreneurial journey with confidence:

    Step 1: Choose Your Business Structure in Indiana

    Before registering your business, it’s essential to determine the right business entity. The choice of entity will have implications on liability protection, taxation, and management requirements. Let’s take a closer look at the available options:

    Sole Proprietorship

    The simplest business structure is the sole proprietorship, where the owner and the business are considered the same entity. However, this means the owner is personally liable for the business’s debts and obligations. 

    The advantage is that establishing a sole proprietorship in Indiana is straightforward and involves minimal legal and administrative requirements. In most cases, there’s no need to register with the state, but you may need to obtain local permits or licenses.

    General Partnership

    A general partnership is formed when two or more individuals share ownership and management responsibilities. Each partner is personally liable for the partnership’s debts and legal obligations. Similar to sole proprietorships, you generally don’t need to register a general partnership with the state, but you might have to file a “Fictitious Business Name Registration” in the county where your business operates.

    Limited Partnership (LP)

    A limited partnership consists of one or more general partners who bear personal liability and one or more limited partners who have limited liability, meaning they’re not personally responsible for the partnership’s debts. To establish an LP in Indiana, you must file a “Certificate of Limited Partnership” with the Indiana Secretary of State.

    Limited Liability Company (LLC)

    LLCs offer a flexible business structure that combines the liability protection of a corporation with the tax advantages and simplicity of a partnership. To form an LLC in Indiana, you need to file “Articles of Organization for a Limited Liability Company” with the Indiana Secretary of State. Additionally, you’ll need to create an Operating Agreement to outline the management and ownership structure of the company.


    A corporation is a separate legal entity from its owners (shareholders) and provides limited liability protection. In Indiana, there are two types of corporations: C-corporations and S-corporations. C-corporations are subject to double taxation, while S-corporations pass-through taxation to individual shareholders. 

    To register a corporation in Indiana, you must file either “Articles of Incorporation for a Business Corporation” or “Articles of Incorporation for a Nonprofit Corporation” with the Indiana Secretary of State, depending on the business type. Corporations typically require more formalities, such as creating bylaws, issuing stock, and conducting regular board and shareholder meetings.

    Choosing the right business entity in Indiana is a critical decision that can significantly impact your business’s success. Consider factors such as liability protection, tax implications, and management requirements before making your choice. It’s wise to consult with legal or business professionals if you need assistance in selecting the most suitable entity for your specific needs.

    Step 2: Select a Unique Business Name in Indiana

    One of the critical steps in establishing a business in Indiana is selecting and registering a unique business name. However, the process involves more than just picking a name at random. Indiana offers three primary methods for naming your business: 

    When starting a business in Indiana, it’s mandatory to register a legal entity name with the state. This name will be used to identify your company officially, making it essential to choose a name that’s distinct and not already in use by another business. Additionally, Indiana naming regulations specify the use of appropriate company suffixes such as LLC, LP, or Corp. 

    The entity name must accurately reflect the nature of the business being registered. To determine if your preferred name is available, you can use the Indiana Secretary of State’s INBiz database for a quick and convenient name availability search.


    Securing a trademark is a powerful method to protect your business name or logo at a national level. A trademark grants exclusive rights and prevents others from using an identical or similar name or logo for similar goods or services. Before applying for a trademark in Indiana, it’s crucial to conduct a thorough search in the US Patent and Trademark Office (USPTO) database to ensure that your desired name or logo has not already been registered by another entity. 

    Once your trademark is registered, it offers nationwide protection for your intellectual property. However, it’s important to note that a trademark does not automatically grant unrestricted use of the name or logo in all situations, and additional legal considerations may arise.

    Doing Business As (DBA)

    Indiana allows businesses to operate under an official name while using another name in the market. This alternate name is referred to as a Doing Business As (DBA) name. To register a DBA name, you must file a Certificate of Assumed Business Name with the Indiana Secretary of State. Unlike legal entity names and trademarks, DBA names are not required to be unique at the state level. 

    However, they’re still subject to federal trademark laws. Registering a DBA name can be beneficial if you want to use a more descriptive or marketable name while maintaining the legal identity of your business.

    By familiarizing yourself with Indiana’s naming regulations and conducting proper searches, you can select the most suitable method to safeguard your business name effectively. Whether you choose to pursue all these three options or opt for a single approach, maintaining consistency across all registration methods can provide additional benefits for your business in the long run.

    Step 3: Check Business Name Availability in Indiana

    Before proceeding to register your business, it’s crucial to ensure that your desired business name is available for use. To do this, conduct three types of searches to thoroughly check for its availability:

    The first step is to perform a federal trademark search to check if your intended business name is already trademarked. Federal trademarks take precedence over state-level registrations, so it’s essential to make sure your preferred name isn’t already trademarked. If it’s, you will need to choose a different name.

    To conduct a federal trademark search, visit the U.S. Patent and Trademark Office (USPTO) website and use the TESS Search tool.

    Once you have confirmed that your business name isn’t trademarked, proceed to check its availability for use in Indiana. Use the Indiana Business Search tool to search for registered business names within the state.

    During your search, make sure that not only your exact business name is available but also ensure that there are no significantly similar business names being used by other companies.

    In addition to checking trademark and state-level availability, consider searching for the .com version of your business name. While not every business may require a website, it’s recommended to secure the .com domain for your business name if possible.

    Registering the .com domain of your business name with ZenBusiness ensures exclusive ownership, preventing others from using the same website name. With affordable rates, securing your domain is a cost-effective way to protect your business identity.

    By conducting these three searches, you can confidently determine if your desired business name is available for use and registration.

    Step 4: Form Your Business With the State of Indiana

    After deciding on your business structure and name, the next crucial step is to formally register your business with the state of Indiana.

    • Registering an Indiana LLC: To register your Indiana Limited Liability Company (LLC), you must file the Articles of Organization with the Indiana Secretary of State Business Services Division. This can be done online or through the mail.
    • Registering an Indiana Corporation: For an Indiana corporation, you need to file the Articles of Incorporation with the Indiana Business Services Division.

    Protect Your Business Name With a Trademark

    Once you have confirmed the availability of your chosen business name and secured it, you have the option to apply for a trademark. While this process may involve costs ranging from $225 to $400, plus attorney fees and a renewal fee every 10 years, it provides your company with nationwide brand protection supported by federal law.

    A registered trademark grants you legal precedence, which can be valuable if others attempt to use the same or a similar name for their business. However, for most small businesses that operate locally, obtaining a trademark may not be necessary.

    How to File an Indiana Fictitious Name – DBA?

    To file an Indiana Fictitious Name (Doing Business As or DBA), follow these steps:

    1. Choose a Fictitious Name: Select the name you want to use for your business, ensuring it’s not already in use by another business in Indiana
    1. Check Name Availability: Verify the availability of your chosen name by conducting a name search through the Indiana Secretary of State’s website or office
    1. File the Application: Obtain the “Application for Registration of a Business Name” form from the Indiana Secretary of State’s website or office. Complete the form with accurate information
    1. Notarize the Application: Sign the application in the presence of a notary public, as the form requires notarization

    How to Change the Name of an Indiana Business?

    If you need to change the name of your business in Indiana, there are two methods you can follow:

    1. Filing for an Assumed Business Name (DBA Name): For sole proprietorships and general partnerships looking to operate under a different name without altering their legal name, filing for an assumed business name (also known as a “Doing Business As” or DBA name) is the simplest approach.

    A DBA name allows LLCs and corporations to operate using brand names that do not include the required “LLC” or “Inc.” suffix found in their legal names. It streamlines business operations and avoids the need to file an amendment.

    1. Submitting an Amendment for LLCs and Corporations: If you want to change the legal name of your LLC or corporation, filing an amendment is the best option. This involves submitting the appropriate forms for the desired name change.

    Forms for both options can be found online, and along with a $30 filing fee, you can complete the submission process.

    By following these steps, you’ll successfully form your business in Indiana, ensuring that it operates under the appropriate structure and name, with trademark protection for added security and brand recognition.

    • Business Entity Types: Different business entity types have different naming requirements. For example, if you’re forming a corporation, your business name should include words like “Corporation,” “Incorporated,” “Company,” or an abbreviation of these terms.
