DBA (Doing Business As)
The paperwork that legally connects a brand name to the entity behind it. Cheap, fast, frequently skipped, and the reason banks reject deposits when a founder operates under an unregistered name.
A DBA is required the moment a business operates or signs contracts under any name other than its legal entity name. A sole proprietor named Jane Smith selling skincare as Petal & Stem needs one. An LLC called Acme Holdings selling products under the brand name Mira Beauty needs one. An LLC whose registered name already matches the brand on the website does not.
A DBA, short for “doing business as,” is the public registration that legally links a brand name to the entity behind it. It is cheap, fast, and routinely skipped by first-year founders, which is why banks reject deposits, payment processors freeze accounts, and courts throw out contracts signed under unfiled brand names. The fee is usually $10 to $100, the filing takes about 15 minutes online in most states, and six states require an additional newspaper publication that adds $40 to $200 and a few weeks of waiting.

What a DBA Is
A DBA is a public registration filed with the state, county, or city, depending on the jurisdiction. The document lists the legal entity (either a person’s full legal name for a sole proprietor or the registered name of an LLC or corporation) and the public-facing name that entity will operate under. Once accepted, the filing is searchable in the state or county business name database, and the brand can sign contracts, open bank accounts, and accept payments under the assumed name.
The term comes from the phrase “doing business as.” A sole proprietor named Maria Lopez who runs a candle business signs contracts as “Maria Lopez DBA Wickwell Candles.” An LLC called Lopez Holdings LLC signs them as “Lopez Holdings LLC DBA Wickwell Candles.” The DBA does not replace the entity, it attaches a public name to it.
Different states use different labels. California, Florida, and Illinois call it a “fictitious business name.” Texas, Georgia, and New Mexico call it a “trade name.” New York, Illinois, and North Carolina call it an “assumed name.” The legal effect is the same regardless of label.
What a DBA Is Not
A DBA does not create a separate legal entity. The entity behind the DBA is still whatever it was before, either the sole proprietor’s personal name or the existing LLC. A lawsuit against a DBA reaches whoever owns the DBA, which means a sole proprietor’s personal assets stay exposed even with a DBA on file. Liability protection comes from forming an LLC, not from filing a DBA.
A DBA does not provide trademark rights. State registration of a name means the state recognizes that the entity operates under it, nothing more. Another business in another state can use the same name with no legal conflict until one of them files a federal trademark. A DBA is local, a trademark is national, and the two solve different problems.
A DBA does not open a bank account on its own. Banks ask for the underlying entity (a sole proprietorship’s owner with an SSN or a registered LLC with an EIN) along with the DBA certificate. The DBA tells the bank what name to print on the account. The entity is what makes the account possible.
When a DBA Is Required
The trigger is operating under any name that is not the legal entity’s name. Several common situations:
A sole proprietor using any brand name. A sole proprietor’s legal business name is the owner’s full legal name. Jane Smith selling soap as Jane Smith is fine without a DBA. Jane Smith selling soap as Petal & Stem needs one. The line is whether a brand name appears anywhere a customer or vendor sees it.
An LLC whose registered name differs from its public brand. Many founders form an LLC with a holding name (Lopez Holdings LLC, BBG Group LLC) and then launch a brand under a separate name. The LLC’s filed name is what the state recognizes, and anything else the business sells under requires a DBA.
A second brand under the same entity. One LLC can hold several product lines, with each public name registered as its own DBA. A skincare brand and a candle line operating under the same LLC need two separate filings.
A business bank account under the brand name. Banks require either the entity’s exact registered name on the account or a DBA certificate matching the brand name. A check written to “Wickwell Candles” cannot be deposited into an account in Maria Lopez’s name without proof of the link.
Online platform accounts. Stripe, Shopify Payments, and most processors require the business legal name on file to match the IRS record. A DBA reconciles the public brand name customers see on the storefront with the legal name on the underlying account.
When a DBA Is Not Required
If an LLC’s registered name matches the brand exactly, no DBA is needed. Mira Beauty LLC selling products as Mira Beauty operates entirely under its filed name, and the website, the bank account, the contracts, and the storefront all use the registered LLC name the state already recognizes.
A sole proprietor using only her full legal name also does not need one. A consultant operating as “Jane Smith Consulting” technically needs a DBA in most states because the word “Consulting” makes it a name other than the legal name. A consultant operating only as “Jane Smith” does not.
How to File
The filing location depends on the state. Some states process DBAs through the Secretary of State, others delegate to the county clerk or a state business division, and a few require both a state and a county filing.
The process in most states:
- Search the name first. Each state and county maintains a public database of registered names, and filing a name already in use is rejected with the fee usually non-refundable. The same search should also check the USPTO trademark database so the new DBA does not collide with a federally trademarked name in the same category.
- Complete the form. State or county forms ask for the entity’s legal name, address, owner information, and the proposed DBA name. Most are filed online with a credit card.
- Pay the filing fee. Fees range from $10 in some Texas counties to $100 in New York, with most states falling in the $25 to $50 range.
- Publish, if required. California, Florida, Georgia, Minnesota, Nebraska, and Pennsylvania require the new DBA to be published in a local newspaper, usually for four consecutive weeks. The newspaper issues an affidavit of publication, which is then filed with the county to complete the registration. Publication adds $40 to $200 and 2 to 4 weeks.
- Receive the certificate. The state or county issues a stamped certificate, and banks, suppliers, and platforms ask to see it before opening accounts under the DBA name.
Renewal rules vary. Most states require renewal every five years, although Texas issues DBAs for 10 years and a handful of jurisdictions run on shorter cycles. Missing a renewal voids the DBA and forces a full refiling.
DBA vs. Trademark
A DBA gives the right to operate publicly under a name within one state or county. A federal trademark gives exclusive nationwide rights to use that name in a specific category of goods or services. They solve different problems, and most brands eventually need both.
A DBA is filed with a state or county for $10 to $100 and takes effect in days or weeks. A federal trademark is filed with the United States Patent and Trademark Office, costs $250 to $350 per class of goods, and takes 8 to 14 months to register. The DBA is the operational permission slip that lets a founder run the business under the brand name. The trademark is the legal mechanism that stops another business from using the same name in the same category anywhere in the country.
A founder selling skincare as Petal & Stem in California needs the California DBA to open the bank account and run the storefront. She needs the federal trademark to stop a similar brand in Florida from using “Petal & Stem” on its own skincare line.
Common Mistakes
Skipping the filing and operating under an unregistered name. Banks reject deposits, payment processors freeze accounts when the legal name on file does not match the public brand, and courts can refuse to enforce contracts signed under an unfiled name. Several states classify operating an unregistered DBA as a misdemeanor with daily fines for ongoing non-compliance.
Treating a DBA as trademark protection. A DBA is a state registration, not exclusive rights. A second business can file the same DBA in another state, or file a federal trademark over a state DBA and force the original user to change the name. Real brand protection requires a trademark filing with the USPTO.
Forgetting to renew. Most states void a DBA the moment a renewal lapses, and the brand then operates unregistered until the founder notices, usually when a bank or supplier asks for an updated certificate.
Not checking name availability first. A DBA filing rejected for a duplicate name still costs the fee, and state name databases are free to search before paying.
Using a DBA to skip forming an LLC. Filing a DBA under a sole proprietor’s name gives the business a brand but no liability shield. Customers and creditors can pursue the owner’s personal assets the same as before. Forming an LLC and then filing a DBA under it is the cleaner setup for most founders past their first year of revenue.
Frequently Asked Questions
Can one LLC have multiple DBAs?
Yes. A single LLC can file as many DBAs as it wants, each registered separately. Each public brand operates under its own DBA, although legally all of them are still the same LLC. A lawsuit against one DBA reaches every asset of the LLC.
Does a DBA give a brand exclusive rights to the name?
No. A DBA is recognition by the state or county that an entity operates under a given name. Another business in another jurisdiction can use the same name, and a federal trademark filed later can override an existing DBA. Exclusive rights require a trademark.
Is a DBA the same in every state?
The legal effect is similar, although the label varies. Fictitious business name, assumed name, and trade name are all DBA equivalents. Filing rules, fees, renewal periods, and publication requirements vary by state.
Do online businesses need a DBA?
Yes, on the same trigger as offline businesses. If the storefront, the email signature, or the bank account uses a name different from the registered legal entity, a DBA is required in the state where the business is registered.
Can a DBA name include the words “LLC” or “Inc.”?
No. Most states prohibit DBAs from using entity-suffix words, because the DBA is not itself a legal entity. A DBA is “Petal & Stem,” never “Petal & Stem LLC,” unless the underlying LLC’s actual registered name is Petal & Stem LLC.
How fast can a DBA be filed?
In states without publication requirements, the certificate can be issued within 1 to 5 business days. States with publication (California, Florida, Pennsylvania, Georgia, Nebraska, Minnesota) take 4 to 8 weeks because of the newspaper notice period.
Does a DBA need its own EIN?
No. A DBA uses the EIN of the underlying entity. A sole proprietor’s DBA uses her SSN or the EIN she already obtained for her sole proprietorship. An LLC’s DBA uses the LLC’s EIN.
