How to File a DBA in Louisiana 2026: Cost, Process, and Timeline
The complete 2026 guide to filing a Louisiana Trade Name: $75 state fee, 5-10 business days processing, and how File.Business handles the entire registration including renewal tracking.
What a Louisiana Trade Name Actually Is
A Louisiana Trade Name is the formal registration that allows a person or business to operate under a name other than their legal name. For a sole proprietor named John Smith operating a coffee shop called "Bluebird Brew," the DBA registration links the trade name "Bluebird Brew" to the underlying legal name. For an LLC named "Acme Holdings LLC" launching a consumer brand called "Bluebird Coffee," the DBA filing registers the brand name as a trade name of the parent entity. Without a Trade Name registration, the business is legally operating only under the underlying legal name.
Louisiana trade name registration through geauxBIZ portal; $75 fee includes 5-year registration. This is one of the distinguishing features of Louisiana's DBA system. Filing is done at the state level only, with typical processing of 5-10 business days. Louisiana does not require newspaper publication.
When you need a Louisiana Trade Name
Four scenarios consistently require a Louisiana Trade Name registration: (1) a sole proprietor doing business under any name other than their personal legal name; (2) an LLC or corporation launching a brand, product line, or division under a name different from the registered entity name; (3) an existing business expanding into a new line of business that warrants a separate brand identity; (4) a parent entity acquiring a business and wanting to continue operating the acquired brand without renaming the entity itself.
Why the DBA matters even when you have an LLC
Many founders assume that forming an LLC eliminates the need for a DBA. It does not. The LLC name on the public record is the only name the entity can legally use for contracts, invoices, and banking, unless a DBA is registered for an alternate name. If your LLC is "Smith Holdings LLC" but you want to do business as "Bluebird Coffee," you need a Louisiana Trade Name registration. Without it, you cannot legally accept payments to "Bluebird Coffee," open a bank account in that name, or sign contracts using that name.

The Louisiana Trade Name filing process is a 5-step sequence. Following the order below prevents the most common rejection reasons and avoids missing the publication or renewal requirements where applicable.
Step 1: Confirm name availability
Before filing, search the Louisiana business name database to confirm that the proposed Trade Name is not already in use by another registered business in the state. The search is free and available through geauxbiz.com (or the relevant county portal where applicable). A name conflict will cause rejection of the filing.
Step 2: Gather required information
The Louisiana Trade Name filing requires: the proposed trade name; the legal name of the owner (individual, LLC, corporation, or other entity); the principal business address; a brief description of the business activity; and the signature of an authorized signer. For LLCs and corporations, the entity's state file number is also required.
Step 3: File the Trade Name with Louisiana Secretary of State
Submit the completed registration through geauxbiz.com (or the relevant county clerk for county-level filings). Online filing is typically processed in 5-10 business days; paper filing takes longer. The state filing fee is $75.
Step 4: Complete publication (where required)
Louisiana does not require newspaper publication for Trade Name registrations, the filing is complete once accepted by Louisiana Secretary of State.
Step 5: Calendar the renewal
The Louisiana Trade Name is valid every 5 years. Set a calendar reminder for 60-90 days before the renewal deadline to allow time for processing.
Common Louisiana DBA Mistakes to Avoid
Four mistakes consistently cause delays or rejections for Louisiana Trade Name filings.
Mistake 1: Choosing a name too similar to an existing registered name
Louisiana's name availability check is strict about confusingly similar names. "Bluebird Coffee" and "Blue Bird Coffee" or "Bluebird Coffee Co." may all conflict with each other. Search broadly before settling on a name; consider variations and abbreviations to confirm availability.
Mistake 2: Failing to update the DBA when business information changes
Louisiana Trade Name registrations must be updated when the underlying business information changes, owner address, principal business address, or ownership structure. Operating under a DBA tied to outdated information can complicate banking, contracts, and due-diligence reviews.
Mistake 3: Forgetting to renew on time
Louisiana Trade Name registrations expire every 5 years. An expired DBA cannot be used in contracts, invoices, or banking. Renewal must be filed before expiration to maintain continuity. If a DBA lapses, a new filing is typically required, and another business may have registered the name in the interim.
Mistake 4: Confusing DBA registration with trademark protection
A Louisiana Trade Name registration grants the right to operate under the name in Louisiana, but it does NOT grant trademark protection. Another business in Louisiana can register the same DBA later if no trademark conflict exists. To protect the name from use by others, file a state or federal trademark registration in addition to the DBA. Trademark and DBA are complementary, not substitutes.
