If your LLC does business under any name other than its exact legal name, you’ll usually need to register that name. In most places this is called a DBA (“doing business as”). Depending on the state, you’ll also see it called an assumed name, fictitious name or trade name.
Say your company is registered as “Sunrise Holdings LLC” but your coffee shop’s sign reads “Harbor Roast.” Harbor Roast needs to be registered as a DBA of Sunrise Holdings LLC. The LLC stays the legal owner and remains responsible for everything done under the brand.
LLC Name vs. DBA: What’s the Difference?
Your LLC’s legal name is the one on your approved formation documents. It’s the name that signs contracts, owns assets and appears on tax filings.
A DBA is just another name the same company uses publicly. Registering one doesn’t create a new company or change your legal name.
Your contracts and invoices should show the connection, for example “Sunrise Holdings LLC d/b/a Harbor Roast.” Customers and suppliers should always be able to see which legal entity they’re dealing with, especially if your website and ads only show the brand name.
When Does an LLC Need a DBA?
Whenever it trades under a name that isn’t its exact legal name. Even leaving off “LLC” can count as a different name in some states. Rules and exemptions vary, so check the jurisdiction where you’ll use the name.
Florida requires businesses to register a fictitious name before using it, unless an exemption applies. An LLC trading under its full legal name doesn’t need one.
Buying a domain, claiming a social media handle and registering a business name are three separate things. Doing one doesn’t take care of the others.
Where and How to Register
It depends on the state. Some handle DBAs at state level, some at county level, and some use both. Florida registers fictitious names centrally through the Division of Corporations (Sunbiz).
Florida also has a newspaper requirement. Before registering, the name must be advertised at least once in a newspaper in the county where the business’s principal place of business is located. You don’t submit proof, but you certify that it’s been done when you sign the application.
The Florida filing fee is $50, and the registration is valid for five years. Factor in the newspaper ad and processing time before you order signs or print packaging.
Does a DBA Protect Your Business Name?
No, and this is the most common misunderstanding. A DBA is a disclosure, not ownership. Florida states plainly that registering a fictitious name doesn’t stop anyone else from using or registering the same name. Texas likewise treats assumed name filings as separate from any right to exclusive use.
If the name matters to your business, run a trademark search before investing in it, and consider filing a trademark. The state accepting your DBA doesn’t mean the name is free to use. And owning the domain doesn’t give you trademark rights either.
Does a DBA Create Separate Liability Protection?
No. A DBA isn’t a separate legal entity. If Harbor Roast is sued, the claim is against Sunrise Holdings LLC, and everything the LLC owns is exposed, including assets used in its other activities.
If you’re adding a business line with different risks or different owners, a DBA may not be enough. Our article on whether one LLC can operate multiple businesses explains when a separate LLC is the better choice.
DBA vs. Changing Your LLC’s Legal Name
A DBA lets you keep your legal name and trade under another. Changing the legal name is a different process. In Texas, for instance, it requires an amendment to the company’s certificate of formation. Florida uses Articles of Amendment.
If you’re rebranding for good and want contracts, bank accounts and tax records under the new name, a legal name change may be cleaner. If you just want a customer-facing brand, a DBA is usually enough.
Getting Paid Under Your DBA
Ask your bank and payment processor before you start invoicing under the brand. Most will want to see the DBA registration and add the name to your account. Until they do, a check made out to “Harbor Roast” may be hard to deposit.
Keep the registration certificate with your company records. The owner shown on the DBA must match the LLC that holds the bank account.
Renewing a DBA
Renewal rules vary by state. Florida fictitious names expire on December 31 of the fifth year after registration and must be renewed in that final year. Put the date on your calendar as soon as the registration is approved.
Renewing the DBA is separate from keeping the LLC itself active. Our guide to keeping an LLC in good standing covers the LLC side.
