LLC vs DBA: What's the Difference and Which Do You Need?

What is a DBA?

DBA stands for doing business as. It registers a trading name that differs from your legal name, and it goes by several names depending on the state: fictitious business name, assumed name, or trade name.

If Jane Doe runs a bakery as Sunrise Breads without forming a company, Sunrise Breads is a DBA. The legal person doing business remains Jane Doe; the DBA simply tells the public and the state which name she trades under.

Registration is usually inexpensive and quick, often filed with the county or the state depending on where you are. Many banks require a DBA registration before they will open an account in the trading name, which is the most common practical reason people file one.

What does a DBA not do?

A DBA creates no legal separation between you and the business. If the business is sued or cannot pay a debt, your personal assets are exposed exactly as they would be without it. This is the single most important thing to understand, and it is the point most often misunderstood.

A DBA also gives no exclusive right to the name. Registering a fictitious name is not a trademark, and it usually does not stop another business using the same name - even in the same state, depending on local rules.

It does not change your tax position either. Income earned under a DBA is reported the same way it would be without one. A sole proprietor with a DBA is still a sole proprietor, filing the same way and paying self-employment tax on profits.

• No liability protection - your personal assets remain exposed.
• No exclusive rights to the name - that is a trademark question.
• No change to how the income is taxed.

When should you choose an LLC instead?

Choose an LLC when the risk of the business reaching your personal assets is real. Signing client contracts, selling physical products, holding property, hiring people, or doing work where a mistake could cost more than you can absorb are all clear signals.

Choose an LLC when a client, platform or insurer requires you to contract as an entity. Some enterprise customers will not sign with an individual at all, and some payment and banking arrangements assume a registered company.

A DBA alone can be enough for genuinely low-risk work where you simply want to trade under a business name - a small side project, a freelance practice with modest revenue and no contract exposure. Be honest about which of those describes you, because the DBA is cheap precisely because it does nothing protective.

Can an LLC have a DBA?

Yes, and this combination is common and often the right answer. An LLC files a DBA when it wants to trade under a name different from its registered legal name.

Say your company is registered as Doe Holdings LLC but you market a product as Sunrise Breads. Filing a DBA lets the company trade, invoice and bank under that name while the legal entity - and its liability protection - remains Doe Holdings LLC. One entity can hold several DBAs, which is how a single company runs multiple brands without forming a company for each.

The liability protection comes from the LLC, not the DBA. A DBA under an LLC is purely a naming convenience layered on top of a structure that is already doing the protective work.

What does each cost?

A DBA is typically inexpensive - often somewhere between $10 and $100 depending on the state or county - and many require renewal every few years. Some states also require you to publish notice of the fictitious name in a local newspaper, which adds cost.

An LLC costs more to start and, more importantly, keeps costing. State filing fees range from $35 in Montana to $500 in Massachusetts, and recurring obligations continue every year: Delaware charges a flat $300, California an $800 minimum franchise tax, Wyoming a minimum $60 annual report. A registered agent adds roughly $50 to $125 a year.

So the comparison is not really about price. A DBA is cheap because it is a name registration; an LLC costs more because it is an entity that does something. Paying $50 for a DBA when you needed liability protection is not a saving.

How do you register a DBA?

Where you file depends on the state. Some states register fictitious names centrally with the Secretary of State; others handle it at county level, so two businesses in the same state can file in different places. Search for your state name plus "fictitious business name" or "assumed name registration" to find the correct office.

The filing itself is short: your legal name or the company's registered name, the trading name you want to use, the business address, and the fee. Approval is often quick, and several states require you to publish notice of the new name in a local newspaper for a set period, which adds both cost and delay.

Most DBAs expire. Renewal periods commonly run three to five years depending on the state, and an expired registration can mean a bank refuses to keep accepting payments in that name. Diarise the renewal the day you file it, in the same place you keep your other company deadlines.

• Filed with the state or the county, depending on where you are.
• Some states require newspaper publication of the new name.
• Most registrations expire and need renewing every few years.
