How to File a DBA in Missouri: Corp 56 Form, Fees, and Penalties

To file a DBA in Missouri, submit Form Corp 56 (Registration of Fictitious Name) to the Secretary of State, either through the online business portal or by mail, with a $7.00 filing fee. Missouri law calls a DBA a “fictitious name,” and you must register within five days of starting to do business under it.¹

Who Has to File

If you operate a business under any name other than your true legal name, Missouri requires you to register it.² That covers individuals, general partnerships, corporations, and other business organizations.¹

One exception: a partnership or entity formed to practice a licensed profession does not need to register, even if it handles ordinary business transactions alongside the professional practice.¹ Everyone else has five days from the start of business under the name to get the filing in.

Check the Name First

Before you fill out the form, search the Secretary of State’s online business database to see if your chosen name is already in use.³ The search is preliminary and doesn’t guarantee availability, but it will flag obvious conflicts.

Missouri also limits what the name can say. It cannot contain any word or phrase implying it is a government agency, and it cannot be “seriously misleading” to the public.¹ Worth knowing up front: registering a fictitious name does not give you exclusive rights to it. Another business can register the same or a similar name. Brand ownership comes from a federal trademark, not a Missouri DBA.

What the Corp 56 Form Asks For

The registration form requires three categories of information set by statute:¹

The exact fictitious name you want to register.
The physical business address. A street address is required; a P.O. Box can supplement it but cannot replace it.⁴
The full legal name and address of every person or entity with an ownership interest.

Ownership percentages are optional in most cases. The one situation where you must list exact percentages: if any owner wants to claim they are not jointly and severally liable for the business’s debts, the registration has to show every owner’s share.¹ If the owners listed equal 100% and there are more owners to add, attach them on a separate page.⁴

Every listed owner has to sign. Signing is an affirmation under penalty of law that the information is true and that all parties authorized the filing. A false statement is punishable as a class B misdemeanor for making a false declaration.⁵

How to Submit the Filing

Missouri gives you two ways in, and the $7.00 fee is the same either way.⁶ There is no separate county filing; the Secretary of State handles everything.

Online

Filing through the Secretary of State’s online business portal is faster. Create a user account, enter the information, and pay the $7.00 electronically. Credit card and e-check payments carry a small convenience fee from the payment processor, not the state.⁶ The system generates a certificate of registration you can print once the filing goes through.

By Mail or In Person

Download Corp 56 from the Secretary of State’s website, have all owners sign with original signatures, and mail it with a $7.00 check or money order payable to “Secretary of State.”⁷ The address is:

Corporations Division
P.O. Box 778
Jefferson City, MO 65102⁸

You can also drop the form off at the Jefferson City office or any Corporations Division branch office.⁷ Paper filings take longer to process. If you’re close to a deadline, file online.

Keeping the Registration Current

A Missouri fictitious name registration is good for five years from the filing date. It expires automatically if you don’t renew. The renewal window opens six months before expiration, and you have to file within that window to keep the registration continuous.¹ Renewal costs the same $7.00 as the original.⁶ Miss it and you have to start over with a fresh filing.

If ownership changes or the business ceases to exist, Missouri law gives you five days to file a cancellation.¹ Cancellation uses Form Corp 14, needs the signature of at least one listed owner, and has no fee.⁹ You’ll need the registration number and the name exactly as originally filed. For changes short of cancellation, such as adding or removing an owner, file an amendment for the standard $7.00.⁶ Changing to a different name altogether means cancelling the old registration and filing a new one.

What a Missouri DBA Does Not Do

A fictitious name registration is a transparency tool. It creates a public record linking a trade name to its actual owners. It does not give you ownership of the name or stop anyone else from using it. Brand protection comes from a federal trademark through the U.S. Patent and Trademark Office, which is a separate process.¹⁰ It also cuts the other direction: if someone already holds a federal trademark on your chosen name, Missouri approving your DBA will not shield you from an infringement claim.¹¹ A quick search of the USPTO trademark database before filing is worth the time.

What the certificate does help with is banking. Federal banking rules let banks use your fictitious name certificate to verify the identity of a sole proprietorship when opening an account under the trade name.¹² Without the certificate, most banks will refuse.

Penalty for Skipping Registration

Doing business under a fictitious name without registering it is a misdemeanor in Missouri.¹³ Beyond the criminal classification, an unregistered business runs into practical problems: trouble enforcing contracts, no bank account in the business name, and no public record tying you to the brand. For $7.00 and a short form, the registration is the simpler path.
