Is a Fictitious Name the Same as a DBA in Florida?

In Florida, a fictitious name and a DBA are the same thing. The Florida Division of Corporations uses “fictitious name” as its official term, but it treats “doing business as” and “DBA” as interchangeable labels for the same filing.¹ If you operate under any name other than your own legal name or your entity’s registered name, you have to register that name with the state. The rules, the $50 fee, and the five-year expiration apply the same way regardless of which term you use.

Why the Terminology Differs

Most states call this filing a DBA. Florida’s statute calls it a fictitious name, and the Division of Corporations uses that language on every form and page. There is no legal distinction between the two words. A business owner from Georgia or Texas who hears “fictitious name” in Florida is hearing a local label for the same registration they already know.

Who Has to Register

Florida’s Fictitious Name Act, Section 865.09, requires registration whenever a person or business entity transacts business under a name other than its legal name.² For a sole proprietor, that means any business name that doesn’t include your full legal surname. For a corporation or LLC, it means any name different from the entity name already on file with the Division of Corporations.

The statute exempts three groups: attorneys actively licensed in Florida, professionals licensed by the Department of Business and Professional Regulation or the Department of Health, and business entities already registered and active with the Division of Corporations. The exemption only holds if those people and entities do business under their licensed or registered name. The moment any of them operates under a different name, the exemption disappears and registration is required.³

What Registration Does Not Do

This is the piece people most often misunderstand. Registering a fictitious name in Florida does not give you ownership of the name, does not stop someone else from registering the identical name, and does not reserve the name for future use.¹ The statute states plainly that registration exists for public notice only and creates no presumption of the registrant’s rights to own or use the name.³

Multiple businesses can legally hold the same fictitious name in Florida at the same time. You can search Sunbiz to see whether your intended name is already in use, but finding a match doesn’t legally stop you from registering it, and your own registration won’t stop the next person either.

How to Register

Filing happens through the Sunbiz e-filing portal or by paper application. Before you file, gather:

The exact fictitious name you want to register.
The business mailing address.
Owner information. For individuals, that’s full name and mailing address. For business entity owners, you’ll also need the entity’s Division of Corporations document number and its federal employer identification number, or you can select “Applied For” or “Not Applicable.”⁴
Proof you advertised the name in a newspaper, which has to happen before you file.

Florida requires you to advertise the intended fictitious name at least once in a newspaper located in the county where your principal place of business sits.¹ You don’t submit the proof with your application. When you sign the registration, you’re personally certifying the ad ran. Keep a copy anyway. If anyone ever challenges your compliance, that receipt is your evidence.

The registration fee is $50.⁵ Once the Division processes your submission, you’ll get an acknowledgment that serves as formal evidence the state recognizes your fictitious name.

Renewal Every Five Years

A fictitious name registration is valid for five years and expires on December 31 of the final year. Renewal has to be filed on or before that date, and the fee is another $50.⁶⁵

There is no grace period and no reinstatement for an expired registration. Miss December 31 and the Division removes it from its records. You start over with a brand-new filing, which means another $50, another newspaper advertisement, and the full process again.⁶ Put the expiration year on a calendar when you first register.

What Happens If You Skip It

Operating under an unregistered fictitious name is a second-degree misdemeanor in Florida, carrying up to $500 in fines or up to 60 days in jail.²⁷ Criminal prosecution is uncommon, but the civil consequence is what actually bites.

Without a registered fictitious name, you cannot bring a lawsuit, maintain a court action, or pursue any legal proceeding related to that business in Florida courts. You can’t sue a customer who stiffed you, enforce a contract, or chase a debt through the court system until you fix the registration.³ Two things cut the other way: failing to register doesn’t invalidate contracts you already signed, and it doesn’t stop you from defending yourself if someone sues you. A party harmed by your noncompliance can also ask the court to award reasonable attorney’s fees and court costs tied to dealing with your unregistered status.

If You Want to Actually Protect the Name

A fictitious name registration and a federal trademark are different tools for different problems. The Florida filing satisfies a state administrative requirement so the public knows who’s behind a business name. A federal trademark, registered through the U.S. Patent and Trademark Office, secures nationwide ownership rights over a brand identifier.⁸ Since the Florida registration doesn’t prevent anyone else from using your name, trademark registration is the route if your name has real brand value. Common-law trademark rights can exist in the geographic area where you actually use the name in commerce, but those rights extend only to your operating territory.

One more boundary worth knowing: adding a DBA does not require a new EIN. Sole proprietors, corporations, partnerships, and LLCs can all add or change a business name while keeping the same federal tax ID.⁹ If the fictitious name eventually replaces your legal business name entirely, you should notify the IRS, but for most owners simply adding a DBA, no IRS filing is needed.¹⁰
