Missouri Fictitious Name (DBA): $7 Filing and 5-Year Renewal

If you want to run your Missouri business under a name other than your legal business name, you need a fictitious name registration. This guide walks you through the filing process, costs, renewal timeline, and what a Missouri fictitious name does and does not do for your business.

What Is a Missouri Fictitious Name or DBA?

A fictitious name, also called a doing-business-as or DBA, is a business name that differs from your legal entity name. If you are a sole proprietor operating under your own name or an LLC operating under a name other than what appears on your formation documents, you file a fictitious name registration to make that operating name official in Missouri.

A Missouri fictitious name registration tells the Secretary of State that your business is also known by another name. It does not create a new business entity, change your ownership structure, or provide legal protection for your business name.

When Do You Need a Fictitious Name Registration in Missouri?

You must register a fictitious name before you use it in business if the name is different from your legal business name. Here are the most common scenarios:

• Sole proprietor using a business name: If you are a sole proprietor named John Smith and want to operate as "Smith's Plumbing," you need a fictitious name registration.
• LLC using a different operating name: If your LLC is legally named "Smith LLC" but you want to market it as "Smith's Plumbing," you register the trading name as a fictitious name.
• Corporation using a different name: If your corporation is legally incorporated as "Smith Holdings Inc." but operates under "Smith's Plumbing," you file the fictitious name.
• Partnership using a different name: If your partnership is legally named one thing but operates under a different name, file the fictitious name.

You do not need a fictitious name registration if you operate under your legal business name exactly as it appears on your formation documents or business license. You also do not need one if you operate as a sole proprietor under your own legal name.

The Missouri Fictitious Name Filing Fee

The Missouri Secretary of State charges a flat $7 fee for fictitious name registration, whether you are filing a new registration, renewing an existing one, or amending the details of a registration. Canceling a fictitious name registration is free.

This $7 fee is final and does not include expedited processing or additional services. Online filings through the Missouri Business Filings portal process immediately, so there is no wait for faster handling.

The low filing fee makes Missouri fictitious name registration affordable even for very small businesses or side ventures. The only cost is the state filing fee, though you may also want to consult a business attorney or accountant to confirm that your operating name does not conflict with existing registered names or trademarks.

How to File a Missouri Fictitious Name Registration

Missouri allows you to file a fictitious name registration entirely online through the Missouri Business Filings portal or by mailing a paper form to the Secretary of State.

Online filing (fastest option): Visit the Missouri Business Filings portal and complete the Registration of Fictitious Name form (Form Corp. 56). You can pay the $7 fee with a credit card, and your registration takes effect immediately after submission. This is the fastest and most reliable method.

Paper filing: You can download Form Corp. 56 from the Missouri Secretary of State fictitious name FAQ page, complete it by hand or typewriter, and mail it to the Missouri Secretary of State, Corporations Division. Processing times for paper filings are not guaranteed, and mailing introduces delays. If you use the paper method, include a check for $7.

The form requires basic information about your business: the fictitious name you want to register, the business address, and the name of each owner of the business along with that owner's percentage of ownership. If you file online, the process takes just a few minutes.

Important: Missouri is a statewide filing jurisdiction only. You do not file a fictitious name at the county level or with your city or town. There is one statewide registration through the Secretary of State, and that is all that is required in Missouri. This differs from some neighboring states that allow or require county-level fictitious name filings.

Processing Time and When Your Fictitious Name Takes Effect

If you file online through the Missouri Business Filings portal, your fictitious name registration is processed immediately. You can begin using the name in business right away once your filing is submitted and confirmed.

Paper filings take longer. The Secretary of State does not publish guaranteed turnaround times for paper filings, but you should expect a delay of several days to a few weeks depending on mail volume and processing speed.

For this reason, online filing is strongly recommended. It is simple, inexpensive, and gives you immediate confirmation and effective date.

How Long Is a Fictitious Name Registration Good For?

A Missouri fictitious name registration is valid for exactly 5 years from the date of filing. After 5 years, the registration expires and is no longer active. You must renew the registration if you want to continue using that fictitious name.

If you stop using the fictitious name and do not intend to use it again, you can cancel the registration. Cancellation is free and can be filed at any time. You do not have to wait for the 5-year term to end.

Renewing Your Missouri Fictitious Name

You can renew your fictitious name registration during the 6-month period immediately before expiration. For example, if your registration expires on January 15, 2028, you can file a renewal on or after July 15, 2027, but you must file before January 15, 2028.

The renewal fee is also $7, and you file it using the same online portal or by mailing a paper form. Renewal extends your registration for another full 5 years from the original expiration date.

If you miss the renewal deadline and your registration expires, you lose the registration and must file a new registration (rather than a renewal) if you want to continue using the name. This resets the effective date and costs another $7.

To avoid lapse, mark your calendar 6 months before your registration expires or set a calendar reminder. The renewal process is as fast and straightforward as the original filing.

What a Missouri Fictitious Name Registration Does NOT Do

This is critical: a Missouri fictitious name registration does not legally protect, reserve, or trademark your business name. Many business owners file a fictitious name thinking they have secured exclusive use of that name, but that is not what happens.

A fictitious name registration simply tells the Missouri Secretary of State that you are using that name. It does not prevent someone else from also registering the same fictitious name or using a similar name. Multiple businesses can file the same or very similar fictitious names in Missouri, and the Secretary of State does not screen for name conflicts at the time of filing.

A fictitious name registration also does not protect your name across state lines. If you want protection in other states, you must file fictitious name registrations in those states as well, or pursue trademark registration with the U.S. Patent and Trademark Office for protection at the federal level.

Additionally, filing a fictitious name does not affect federal trademark law. If someone else has registered a trademark that is confusingly similar to your fictitious name, they have superior rights regardless of your fictitious name filing.

Protecting Your Business Name Beyond Fictitious Name Registration

If you want real protection for your business name, consider these steps:

Federal trademark registration: Register your business name as a trademark with the U.S. Patent and Trademark Office. This provides nationwide protection and establishes that you have the exclusive right to use that name for your type of business. Trademark registration costs significantly more than a fictitious name filing, but it offers genuine legal protection.

Domain name registration: Secure the domain name that matches your business name. This prevents someone else from registering the website address associated with your brand.

Business entity name protection: If you incorporate as a corporation or form an LLC with your desired business name as part of the legal entity name, that provides stronger protection than a fictitious name alone. The Secretary of State will not approve formation documents if the name conflicts with an existing registered entity.

Consult an attorney: A business attorney can advise on name availability, trademark conflicts, and the best protection strategy for your specific business.

Frequently Asked Questions

Do I need a fictitious name registration if I have an LLC? Only if you want to operate under a name different from your legal LLC name. If your LLC is named "ABC LLC" and you operate as "ABC LLC," no fictitious name registration is needed.

Can I reserve a fictitious name before I start using it? Missouri fictitious name registration is for names you are already using or about to use. There is no separate "reservation" process for fictitious names. If you want to reserve a business entity name, you can file a name reservation through the Secretary of State for a $25 fee, valid for 60 days and renewable for up to 180 days total.

What if someone else already filed the same fictitious name? You can still file the same name. Missouri does not prevent duplicate fictitious name registrations. However, the other person may have prior use rights or trademark claims. Before filing, search the Missouri Secretary of State database to see if the name is already in use, and consider consulting an attorney about potential conflicts.

Can I file a fictitious name for multiple businesses? Yes, you can file separate fictitious name registrations for different businesses you operate. Each registration is a separate filing with its own $7 fee and 5-year term.

Do I need a business license in Missouri to file a fictitious name? No state business license is required in Missouri. The fictitious name registration itself is the statewide filing. You may still be required to register with the Missouri Department of Revenue for sales tax, employer withholding, or corporation income tax, and to obtain any licenses required for your specific trade or profession (e.g., contractor license, professional license).

How do I search for existing fictitious names in Missouri? Use the Missouri Secretary of State business search tool to look up registered business names and fictitious names. This is free and helps you see what names are already in use.
