A DBA in Mississippi, officially called a fictitious name under Mississippi Code Ann. § 75-93-1 et seq., lets any business operate under a name other than its legal registered name. Filing is voluntary, not legally required. Mississippi businesses register entirely online through the Secretary of State's portal for a flat $25 state fee, and each registration stays valid for five years before renewal.
What is a DBA in Mississippi?
A DBA (doing business as) is a trade name a business uses instead of its legal registered name. Mississippi's official term under state law is "fictitious name," though "trade name" and "assumed name" refer to the same thing. Miss. Code § 75-93-1 et seq., the Fictitious Business Name Registration Act, governs everything from how you file to what names you're allowed to use.
A DBA does not grant exclusive rights to a name. Any number of businesses can register the same fictitious name, and the Secretary of State will accept each one.
A DBA does not create a separate legal entity. A sole proprietor operating as "Gulf Coast Creative" is still legally Jane Smith. No liability protection flows from the registration—personal assets remain exposed exactly as before.
The purpose of registration is transparency. Under Miss. Code Ann. § 75-93-3, the state wants the public to identify the legal person or entity behind any trade name operating in Mississippi. The state's interest is disclosure, not exclusivity.
Who needs a Mississippi DBA?
Mississippi law does not require any business to register a fictitious name. That said, several real-world situations make filing practically unavoidable.
- Opening a business bank account. Most banks won't open a business checking account under a trade name without a registered DBA.
- Signing contracts and invoicing clients. Using an unregistered trade name on contracts creates confusion about who the legal party is. A dispute over payment becomes harder to resolve if the other party challenges whether you had authority to contract under that name.
- Applying for a business license. Some local licensing authorities require a registered fictitious name before issuing a license to a business operating under a trade name.
- Presenting a professional brand. Clients, vendors, and partners expect consistency between the name on your marketing materials and the name on your paperwork.
DBA requirements by business type
Fictitious name rules apply across every entity type.
- Sole proprietors. Any name other than your own legal name can be registered as a DBA.
- General partnerships. A partnership operating under a name other than the combined surnames of its partners can register a fictitious name.
- LLCs. An LLC can file a DBA to operate under a brand name that differs from the legal name on its Certificate of Formation. The LLC remains the legal entity; the DBA is simply a different name it trades under.
- Corporations. Corporations can register a fictitious name to trade under a different brand while keeping the corporate legal name intact for official filings.
- Foreign entities. Businesses formed outside Mississippi that operate within the state may register a fictitious name through the Secretary of State, following the same process as domestic entities.
In every case, the DBA layers on top of the existing business structure. It doesn't replace it, alter it, or create a new one.
How to get a DBA in Mississippi: Step-by-step
Following the proper filing procedure ensures your fictitious name registration is processed efficiently by the Secretary of State.
Step 1: Check fictitious name availability
Search the fictitious business name database through the Business Services section of the Secretary of State's website. The search is free and takes only a few minutes.
Mississippi does not use the name search as a gatekeeper. The Secretary of State will not reject your application because another business has already registered the same fictitious name—two businesses can legally hold the same registered fictitious name simultaneously. The search is a safeguard for you, not a filter for the state. Knowing whether your proposed name is already in use helps you avoid customer confusion and potential legal challenges.
Also search the U.S. Patent and Trademark Office's federal trademark database. A Mississippi DBA does not protect you from federal trademark infringement claims, so knowing whether your proposed name is already federally trademarked is essential before you commit to it.
Step 2: Gather your filing information
Collect everything before you open the form:
- Your fictitious name—spelled precisely as you intend to use it
- Your legal name or entity name—your personal full name for sole proprietors; the legal name on file with the Secretary of State for LLCs and corporations
- Your Mississippi Business ID—if your business is already registered with the state
- Your principal business address—a physical Mississippi street address
- Your business mailing address—if different from the street address
- Your business type—sole proprietor, partnership, LLC, corporation, or foreign entity
- A short description of your business—for example, "graphic design services" or "residential landscaping"
- Your business email address—this becomes your username for the Secretary of State's portal
If you don't already have a Secretary of State online account, create one before you start the form.
Step 3: File online through the Mississippi Secretary of State
File a Fictitious Business Name Registration through the Business Services portal at sos.ms.gov.
- Navigate to "File Business Documents"
- Select "MS Fictitious Registration"
- Complete the form using your pre-filing checklist
- Review every field—the system validates many fields and flags errors before submission
- Submit
Double-check the spelling of your fictitious name before you submit. Errors require a formal amendment filing to correct, which costs another $25.
Step 4: Pay the $25 filing fee
The fee is due at submission and is non-refundable regardless of outcome. You can pay by credit card (American Express, Visa, MasterCard, Discover), e-check, or ACH. No county filing fees and no newspaper publication requirement add to your total.
Step 5: Receive confirmation and keep records
You'll receive an email confirmation the same day—sometimes within minutes—confirming acceptance or flagging corrections needed. Save your confirmation email and registration certificate. You'll likely need them to open a business bank account, apply for a business license, or sign contracts under your trade name.
How much does a DBA cost in Mississippi?
| Cost item | Amount | Required? |
|---|---|---|
| Initial fictitious name filing fee | $25 | Yes |
| Renewal filing fee (every five years) | $25 | Yes—to keep registration active |
| Federal trademark search (USPTO) | Free | No—but strongly recommended |
| Amendment filing fee | $25 | No—only if you need to correct or update |
| Professional filing assistance | Varies | No |
The $25 state fee is non-refundable once submitted. If you make an error and need to amend the registration, that triggers a separate $25 filing—one more reason to review every field before you submit.
Mississippi DBA name rules and restrictions
Before you can file for a DBA in Mississippi, you’ll need to make sure you’re following the state’s naming rules. The exact rules you’ll need to follow will depend on the type of business entity you choose and the industry you operate in.
Names the Secretary of State will refuse
Your fictitious name cannot imply you've formed a legal entity you haven't actually formed. Under Miss. Code Ann. § 75-93-25, the Secretary of State must refuse registration of a fictitious name that includes entity designators that don't match your actual structure. A sole proprietor cannot use "LLC," "L.L.C.," "Limited Liability Company," "Corporation," "Corp.," "Incorporated," or "Inc." The same restriction applies to "Business Trust," "Professional Corporation," and their variants.
Fictitious names also cannot include terms associated with financial institutions—"bank," "banc," "banco," "banker," "trust company," "savings and loan association," "savings bank," or "credit union"—unless you're operating a regulated financial entity. Names cannot imply association with a government agency, contain false or misleading information, suggest an unlawful purpose, or include a professional title such as "Doctor" or "Attorney" unless you're licensed to use it in Mississippi.
| Restriction | Example of a prohibited name | Why it's disallowed |
|---|---|---|
| Entity designators (type mismatch) | "Coastal Creative LLC" (sole proprietor) | Implies an LLC was formed when it wasn't |
| Corporate suffixes (non-corporation) | "Southern Supply Inc." (partnership) | Implies incorporation when it doesn't exist |
| Financial institution terms | "Delta Savings Bank" (retail store) | Reserved for regulated financial entities |
| Government agency implications | "Mississippi Tax Authority" (private firm) | Creates false impression of official status |
| Words implying unlawful purpose | Any name suggesting illegal activity | Prohibited outright |
| Professional titles without licensure | "Dr. Jones Wellness" (unlicensed owner) | Misleads the public about credentials |
One narrow exception: the Secretary of State may allow a DBA containing a restricted term if, in the Secretary of State's sole discretion, the term is not misleading. Don't build your branding around a name that requires discretionary approval. If your desired name contains a restricted term, consult an attorney before filing.
Registration does not give you exclusive rights to the name
Mississippi law specifically provides that the Secretary of State shall not refuse registration of a fictitious name on the grounds that it is indistinguishable from a previously registered fictitious name, registered trademark, or legal entity name. Someone else can register the exact same fictitious name tomorrow, and the Secretary of State will accept it.
If another business already uses your proposed name under a federal trademark, registering a Mississippi DBA does nothing to protect you from an infringement claim. If protecting your brand is a priority—especially beyond Mississippi's borders—a federal trademark registered with the USPTO is the right tool. It grants exclusive nationwide rights within a specific category, which a fictitious name registration cannot do.
How long does a Mississippi DBA last? Renewal rules
A Mississippi fictitious name registration lasts five years and is renewable indefinitely. The registration expires on December 31 of the year in which the fifth anniversary of the original registration occurs. Register in 2025, and your registration expires December 31, 2030.
When and how to renew
Renew any time between January 1 and December 31 of your expiration year. The renewal fee is $25, paid online through the same Secretary of State portal. If you don't renew by December 31, the registration expires and is removed from the public record. Banks that relied on your registration may flag the lapse, and contracts signed under your trade name could raise questions about your authority to use it.
Mississippi sends no automatic renewal notices. Set a calendar reminder at least 60 to 90 days before December 31 of your fifth registration year.
How to amend or cancel a Mississippi DBA
Keeping your fictitious name registration current requires proactive maintenance as your business evolves. Understanding the process for making updates ensures you remain compliant with state requirements.
Amending a Mississippi fictitious name registration
You must file an amendment within thirty days of any material change to the information in your registration. Common triggers include:
- Changing your fictitious name—rebranding from one trade name to another
- Moving your principal business address
- Changing ownership or legal entity name
To amend, log into your Secretary of State account and navigate to "File an Amendment on an Existing Business." The fee is $25, non-refundable once submitted. You'll receive email confirmation the same day. Save it—you may need it to update records with your bank, business license authority, or other third parties.
Withdrawing (canceling) a Mississippi DBA
If your business stops operating under a fictitious name, file a formal withdrawal rather than letting the registration sit idle. To withdraw, deliver to the Secretary of State a statement that includes the legal name of the entity, the fictitious name to which the withdrawal relates, and confirmation that the entity will no longer transact business under that name. Complete this online through the Fictitious Business Name Withdrawal form for a $25 filing fee.
An inactive registration left on the public record creates friction—banks, licensing authorities, and vendors may find a name associated with your legal entity that you're no longer using. Filing a withdrawal keeps the record clean.
The Secretary of State will also cancel a registration if it is not renewed or if a court orders cancellation.
After withdrawing, notify your bank, update contracts and vendor agreements referencing the fictitious name, and revisit any local business licenses issued under that name. The withdrawal only removes the registration from the state's public record.
Mississippi DBA vs. LLC vs. trademark: What's the difference?
A Mississippi DBA, an LLC, and a federal trademark all involve your business name but do three completely different things.
| Restriction | Example of a prohibited name | Why it's disallowed |
|---|---|---|
| Entity designators (type mismatch) | "Coastal Creative LLC" (sole proprietor) | Implies an LLC was formed when it wasn't |
| Corporate suffixes (non-corporation) | "Southern Supply Inc." (partnership) | Implies incorporation when it doesn't exist |
| Financial institution terms | "Delta Savings Bank" (retail store) | Reserved for regulated financial entities |
| Government agency implications | "Mississippi Tax Authority" (private firm) | Creates false impression of official status |
| Words implying unlawful purpose | Any name suggesting illegal activity | Prohibited outright |
| Professional titles without licensure | "Dr. Jones Wellness" (unlicensed owner) | Misleads the public about credentials |
A DBA does one thing: it puts a trade name on the public record. If protecting personal assets is the goal, you need an LLC or corporation. If protecting your brand name from competitors is the priority, only a federal trademark delivers that.
These tools are not mutually exclusive. Many business owners file a DBA, form an LLC, and register a federal trademark, using each for what it actually does.
Common Mississippi DBA filing mistakes and how to avoid them
Making a mistake when filing for a DBA in Mississippi can lead to delays in getting your business up and running. These are some of the most common mistakes business owners make so you can avoid making them yourself.
- Treating registration as name ownership. Filing a Mississippi fictitious name puts your trade name on the public record. It does not prevent other businesses from using the same name. A federal trademark is the tool for brand protection.
- Filing a DBA when you need an LLC. A DBA changes nothing about your liability exposure. If separating personal finances from business debts is the goal, form a separate legal entity.
- Using restricted words without qualifying for them. Including "LLC," "Inc.," "Corp.," financial institution terms, or unlicensed professional titles will get your application rejected. Changing the name later requires a paid amendment.
- Missing the five-year renewal deadline. If you don't renew by December 31 of your fifth registration year, the Secretary of State removes your registration. Set a calendar reminder at least 60 days before the deadline.
- Skipping the trademark search. A Mississippi fictitious name registration does not protect you from federal trademark infringement claims. Check the USPTO database before settling on a name.
- Entering inaccurate information. Typos in your fictitious name, a wrong address, or an incorrect entity type can cause your filing to be returned or require a paid amendment. Review every field before you submit.
Mississippi DBA FAQs
How do I get a DBA in Mississippi?
File a Fictitious Business Name Registration online through the Mississippi Secretary of State's Business Services portal at sos.ms.gov. Search name availability first, gather your legal name, business address, entity type, and business description, then complete the form and pay the $25 filing fee. Registration is confirmed by email, typically the same day.
How much is a DBA in Mississippi?
The state filing fee is $25. That is the only mandatory cost—no county fees, no publication requirement. Renewal costs $25 every five years. Amendments are also $25 each.
What does DBA mean in court?
"DBA" identifies the trade name under which a party operates. A sole proprietor may be named in a lawsuit under both their legal name and their DBA—for example, "Jane Smith d/b/a Magnolia Creative." The DBA does not create a separate legal entity and does not shield the owner from personal liability.
What states do not require DBA registration?
Mississippi is one of several states where DBA registration is voluntary at the state level. Requirements vary by state and change over time. Verify current rules directly with the relevant state's secretary of state office. Even where registration isn't legally required, banks and licensing authorities often make it practically necessary.
Does a Mississippi DBA affect how I pay taxes?
No. A DBA does not change your tax classification or obligations. A sole proprietor with a DBA still reports business income on Schedule C. An LLC with a DBA is still taxed according to its LLC tax election. The IRS does not recognize a fictitious name as a separate taxable entity.
Can I have more than one DBA in Mississippi?
Yes. Mississippi law does not limit the number of fictitious names a business can register. Each DBA requires a separate $25 filing fee and its own five-year renewal cycle—useful for businesses operating multiple brands under one legal entity.
