How to Register a DBA (Fictitious Name) for Your Florida LLC in 2026

Your Florida LLC has a legal name - the name on the Articles of Organization filed with the Division of Corporations. But many Tampa Bay business owners want to operate their business under a different name: a shorter, more marketable brand name, a product line name, or a name that better describes what the business actually does. A DBA - "doing business as" - makes that legally possible.

In Florida, a DBA is called a fictitious name and is governed by Florida Statute Section 865.09. If your LLC does business under any name other than its exact legal name, Florida law requires you to register that name as a fictitious name. Failing to do so is not just a technicality - it carries real legal consequences. This guide covers exactly how the registration works in 2026.

What Is a DBA (Fictitious Name) in Florida?

A fictitious name is any name that a business uses to operate that is not its legal name. For a Florida LLC, the legal name is the name in the Articles of Organization - the name ending in "LLC" or "L.L.C." If the LLC does business under any name that omits or differs from that legal name, a fictitious name registration is required.

Examples of when a Florida LLC needs a fictitious name:

• "Sunrise Marketing Solutions LLC" wants to operate its consulting arm as "Sunrise Consulting" - that shorter name requires a fictitious name registration.
• "Tampa Bay Ventures LLC" wants to run a coffee shop under the name "Harbor Brew" - that trade name requires a fictitious name registration.
• "J&K Holdings LLC" wants to brand a cleaning service as "Sparkle Clean" - fictitious name registration required.

If your LLC uses only its exact legal name (including "LLC") in all business dealings, no fictitious name registration is needed. But the moment you drop the "LLC" or use a different name on your website, signage, invoices, or advertising, you are operating under a fictitious name in Florida.

Why Fictitious Name Registration Matters

Legal Requirement with a Real Penalty

Under Florida Statute Section 865.09(9), any person who violates the fictitious name registration requirement commits a second-degree misdemeanor. That is a criminal offense. The practical enforcement risk is low for most businesses, but the statutory penalty is real and the requirement is not optional.

Required to Sue Under That Name

Florida courts require that a business operating under a fictitious name have that name properly registered before it can file a lawsuit using the fictitious name. If you are trying to collect a debt or enforce a contract under your DBA, an unregistered fictitious name can block you from court.

Provides Public Notice of Who Owns the Business

Fictitious name registrations are public records on Sunbiz.org. The registration links the trade name to the actual legal entity behind it. This transparency requirement is the primary purpose of the Florida fictitious name statute - it prevents businesses from hiding behind anonymous trade names.

How to Register a Fictitious Name in Florida: Step by Step

• Step 1: Search for name availability. Before registering, search Sunbiz.org to confirm no other entity is already using the same fictitious name in Florida. While fictitious name registrations do not automatically block other businesses from using the same name (unlike trademark registration), conflicts can create confusion and legal issues.
• Step 2: Check local county requirements. Some Florida counties have additional local fictitious name or business registration requirements on top of the state registration. Check with your county's clerk of court or business licensing office.
• Step 3: Register at Sunbiz.org. File the fictitious name registration online through the Florida Division of Corporations' website. The registration asks for the fictitious name, the owner's legal name and address (which is the LLC's legal name and address), and basic ownership information.
• Step 4: Pay the $50 filing fee. The state filing fee for a fictitious name registration in Florida is $50. This is a flat fee regardless of the number of fictitious names being registered in a single filing, but each separate fictitious name requires its own registration and fee.
• Step 5: Receive your registration. Online registrations are typically processed and reflected in the Division of Corporations' database within 1-3 business days.

The $50 Fee and What It Covers

The Florida fictitious name registration fee is $50 per fictitious name, paid at the time of initial registration. This is a state fee collected by the Division of Corporations. It does not include:

• County or local business registration fees (which vary by jurisdiction)
• Trademark registration fees (a separate federal process with the USPTO)
• Renewal fees after the 5-year registration period

The $50 registration is one of the least expensive business filings in Florida - but it is not optional if you are doing business under a name other than your LLC's legal name.

The 5-Year Renewal Requirement

Florida fictitious name registrations are valid for 5 years from the date of registration. After 5 years, the registration expires and must be renewed. If you do not renew, the fictitious name registration lapses and you are technically operating under an unregistered fictitious name again - the same violation as never having registered.

Renewal fee: $50 (same as the initial registration fee)

The Division of Corporations sends renewal reminders to the address on file for the registration, but the responsibility for tracking the expiration date is yours. Set a calendar reminder 60 days before your registration's expiration date to avoid an unintentional lapse.

State vs County: Understanding the Two-Level System

Florida has a two-level system for fictitious names: the state-level registration with the Division of Corporations, and county-level requirements that vary by county.

State-Level (Division of Corporations)

The state-level registration at Sunbiz.org is the main fictitious name filing that the statute requires. It registers the name statewide and creates the public record linking the trade name to the LLC. Filing fee: $50. Valid for 5 years.

County-Level Requirements

Some Florida counties - including Hillsborough County (Tampa), Pinellas County (St. Petersburg and Clearwater), Orange County (Orlando), and Miami-Dade County - have additional local business registration or occupational license requirements for businesses operating under fictitious names. These are separate from the state registration and may have their own fees and processes.

Common county requirements include:

• Local business tax receipt (sometimes called a business license) in the county where you operate
• Some counties require a separate county-level fictitious name filing in addition to the state registration
• Municipality-level business licenses if you operate within a specific city

Check with your specific county's clerk of court and your municipality's business licensing office to confirm whether any additional local registrations are required in addition to the state fictitious name registration.

Common Mistakes to Avoid

• Operating under a DBA before registering. The fictitious name must be registered before you use it in commerce. Do not start using the trade name on your website, business cards, or invoices until the registration is complete.
• Confusing a fictitious name with a trademark. A Florida fictitious name registration does not give you exclusive rights to that name. Another business can register the same fictitious name, and neither registration protects against the other. Only federal trademark registration with the USPTO gives you exclusive nationwide rights to a brand name.
• Thinking a business name registration with the Division of Corporations is a fictitious name registration. Registering your LLC's legal name as part of entity formation is not a fictitious name registration. If you want to operate under a different name, a separate fictitious name filing is required.
• Forgetting to update or cancel the registration when the business name changes. If you stop using a fictitious name, or if the LLC dissolves, the fictitious name registration should be cancelled or allowed to lapse. A registration linked to a dissolved LLC can create confusion and stale records.
• Failing to renew after 5 years. The most common fictitious name compliance failure. Set a reminder for 5 years after your initial registration date.

What a Fictitious Name Registration Does NOT Do

It is equally important to understand what a Florida fictitious name registration does not accomplish:

• It does not create a new legal entity. The LLC remains the legal entity. The fictitious name is just a name the LLC operates under.
• It does not give you exclusive rights to the name in Florida. Another LLC can register the same fictitious name. Only trademark registration provides exclusivity.
• It does not affect your tax obligations. Your LLC's tax treatment does not change based on how many fictitious names it has. All income under all fictitious names is income of the same LLC.
• It does not create a new bank account automatically. To open a bank account in the fictitious name, you typically need to provide the fictitious name registration certificate to the bank.
