A DBA only registers a business name. An LLC creates a separate legal business. A DBA (“doing business as”) lets you work under a name other than your own, but it gives you no liability protection. An LLC can protect your personal assets. An LLC can also file a DBA if it wants to use a second name.
The difference
The SBA guide to choosing a business name says a DBA doesn’t give legal protection, but it might be legally required. Registering an entity name, like an LLC’s, protects the name at the state level. A trademark protects it at the federal level.
| DBA | LLC | |
|---|---|---|
| What it is | A registered name | A legal business |
| Where you file | State, county or city, depending on the state | Your state |
| Protects your personal assets | No | Usually, yes |
| Taxes | No change. You are taxed as before. | Same as a sole proprietor by default, with options to change |
| Typical cost | Small fee | $35 to $500 to form, plus most states’ yearly fees |
| Name protection | Little or none | Blocks others from forming a business with the same name in your state |
When a DBA alone is enough
If you are a sole proprietor with low risk and you just want to use a business name on your sign, website and bank account, a DBA may be all you need.
A DBA or LLC name doesn’t give you trademark rights; see how often small businesses file in our data on trademark applications by state.
When you want an LLC
If you could be sued, sign leases or loans, or have a partner, an LLC is the step that protects you. See LLC or sole proprietorship and what an LLC protects.
When you need both
If your LLC is “Smith Home Services LLC” but you want to market as “Sparkle Cleaning,” the LLC files a DBA for “Sparkle Cleaning.” Check that a name is free first with our business name lookup for every state.

FAQ
Is a DBA a business?
No. It is just a name. The business behind it is you (as a sole proprietor or partnership) or your LLC or corporation.
Do I need a DBA if I have an LLC?
Only if you do business under a name that is different from the LLC’s exact legal name.
Does a DBA protect my name?
Not much. It usually doesn’t stop someone else from using the same name. A trademark gives stronger protection.
Can I get an EIN with a DBA?
A sole proprietor can get an EIN and list the DBA name on it. The DBA itself is not a separate taxpayer.
