How to Add a DBA to an LLC

What does DBA mean?

DBA stands for "doing business as"—it's an alternate name your LLC can use instead of its registered legal name. For example, if your LLC is registered as "Jane Jones Enterprises LLC," but you want customers to know you as "J.J.'s Computer Services," you would register the DBA and operate as "Jane Jones Enterprises LLC, DBA J.J.'s Computer Services."

States use different terminology for business names and DBAs. Here are a few terms you might encounter.

• Assumed name: The formal legal name in many states
• Fictitious name: The term for a name that differs from your registered or assumed LLC name
• Trade name: Often used when the name relates to your specific trade or profession

Your LLC can register multiple DBAs to operate different business lines, or use one DBA for marketing while keeping your legal name for official documents.

Where to register a DBA

You'll register your DBA at either the state level or with your county or city government, depending on your state's requirements. Most states require fictitious name registration, though the specific office varies by location.

Here are some methods to find your state's requirements.

• Online search: Search "[Your State] fictitious name registration" or "[Your State] assumed name registration"—for example, "Florida fictitious name registration"
• State business office: Contact the same agency where you filed your LLC formation documents
• County or city clerk: Check with your local government office that handles business regulation
• SBA office: Visit your local U.S. Small Business Administration office for guidance

If you want to use more than one assumed name, you will need to file a separate registration for each name. Unless statewide registration is possible, the assumed name will need to be registered in each county or municipality where the name will be used.

How to register a DBA

Once you determine where to register, you may be able to complete the process online. You can also obtain the proper form from the agency and file it in person. Here's a quick overview of the process.

1. Obtain the form: Download it online or pick it up from the appropriate government agency
2. Complete required information: Provide your LLC's registered name and your desired DBA name
3. Check name availability: Ensure your chosen name isn't already registered or too similar to existing DBAs
4. Pay the filing fee: Typically under $100, though costs vary by location
5. Submit your application: File online or in person with the appropriate agency

Additionally, some states require you to publish a notice of your DBA in an approved newspaper before you can use the name. If such a publication is required, you can usually find a local legal newspaper that offers much lower publication rates than a general circulation newspaper.

Why use a DBA?

LLCs often use DBAs to operate multiple business lines under a single legal entity without forming separate LLCs.

A DBA lets one company run distinct services or brands while maintaining one legal and tax structure. For example, an LLC that manages both rental properties and landscaping work could operate under different public-facing names, such as “Summit Property Management” and “Summit Yard Services," while remaining one unified business behind the scenes.

DBAs can also offer marketing advantages. They allow a business to present itself with a name that better reflects its services, appeals to local customers, or improves visibility. A company registered as “California Wine Outlets LLC,” for instance, might choose to operate a Monterey store under the DBA “Monterey Wine Outlet” to emphasize its local presence rather than a statewide identity.
