Does a DBA give me a separate business or liability protection?

No. A DBA is only a registered trade name. It does not create a separate legal entity and gives no liability protection. For a liability shield you would form an LLC or corporation with the Secretary of State.

California DBA Filing: Fictitious Business Name Cost (2026)

Q: Where do I file a DBA in California?

You file a Fictitious Business Name statement with the county clerk or recorder in the county where your principal place of business sits. California DBAs are county filings, so the exact form, fee, and process vary by county.

Q: Do I have to publish my California DBA in a newspaper?

Yes. After filing, California law requires you to publish the Fictitious Business Name statement in a newspaper of general circulation once a week for four successive weeks, then file an affidavit of publication with the county clerk within 30 days of the last publication.

Q: How long does a California DBA last?

A Fictitious Business Name statement expires five years after filing, on December 31 of the fifth year. You must file a renewal to keep using the name. If the facts have not changed, renewal generally does not require republication.

In California a DBA is called a Fictitious Business Name (FBN), and you file it with the county clerk where your business is located - not with the Secretary of State. You must file within 40 days of starting business, publish the statement in a newspaper once a week for four weeks, and renew every five years. County fees typically start around $26.

What a California DBA Is

A DBA ("doing business as") is a trade name a business uses that differs from the owner's legal name. California's statutory term for it is a Fictitious Business Name, governed by Business and Professions Code sections 17900 and following. A sole proprietor named Maria Lopez who operates as "Bloom Street Bakery," or an LLC that markets a brand different from its exact registered name, generally needs an FBN filing. Filing publicly links the trade name to the true owner so customers and creditors can identify who stands behind the business. For the national concept, see what is a DBA.

Importantly, a DBA is not a business entity. It provides no liability protection and does not change how you are taxed. If you want a liability shield, you form an LLC or corporation with the California Secretary of State instead - a separate process from an FBN filing.

Who Needs to File a Fictitious Business Name

Under California law you generally must file an FBN statement when:

A sole proprietor or partnership uses a name that does not include the surname of every owner, or that suggests additional owners (for example, "& Company").
An LLC or corporation operates under a name that is not the exact name on its Articles of Organization or Articles of Incorporation.

You must file the statement within 40 days of first transacting business under the fictitious name. Banks also commonly require a filed, stamped FBN statement before they will open an account in the trade name, so most owners file early.

How to File a California DBA Step by Step

Because DBAs are county filings, exact steps vary, but the pattern is consistent statewide:

Search the county records. Check the county clerk's FBN index to see whether the name is already registered in that county.
Complete the FBN statement. List the fictitious name, the street address of the principal place of business, and each owner's name and address.
File with the county clerk in the county of your principal place of business, and pay the county filing fee.
Publish the statement in a newspaper of general circulation in that county once a week for four successive weeks.
File the affidavit of publication with the county clerk within 30 days after the last publication date.

If your county has no qualifying newspaper, the statement is posted at the county courthouse instead. Keep the stamped statement and proof of publication with your business records.

The Newspaper Publication Requirement

California is one of the states that still requires newspaper publication of a new Fictitious Business Name. After filing, you must publish the statement in a newspaper of general circulation in the county once a week for four successive weeks, and then file an affidavit of publication with the county clerk within 30 days of the final publication. Many newspapers offer a legal-notice service that handles both the publication and the affidavit. The publication cost is separate from the county filing fee and varies by newspaper. Missing the publication step can make the filing incomplete and, in some counties, void, which can block you from enforcing a contract signed under the trade name until the defect is cured. Start the publication promptly after filing so you can submit the affidavit within the 30-day window and keep the registration valid from the beginning.

California DBA Fees (2026)

DBA fees are set by each of California's 58 counties, so there is no single statewide amount. The table gives the typical structure; confirm exact figures with your county clerk before filing.

Item	Typical amount (2026)	Set by
FBN statement (one name, one owner)	~$26 and up	County clerk
Each additional business name	Small per-name add-on	County clerk
Each additional owner	Small per-owner add-on	County clerk
Newspaper publication (4 weeks)	Varies by newspaper	Newspaper
Renewal (every 5 years)	Similar to initial filing fee	County clerk

Because amounts differ by county, this guide does not quote a single statewide fee; the county clerk's published fee schedule is the authoritative source. For example, Los Angeles County's Registrar-Recorder publishes its current FBN fees online, and other large counties such as San Diego and San Francisco post their own fee tables and forms, which is why quoting one statewide number would be misleading.

Term, Renewal, and Changes

A California FBN statement is valid for five years and expires on December 31 of the fifth year after filing. To keep the name, you file a renewal before expiration. If none of the facts (owners, name, address) have changed, renewal generally does not require you to republish in a newspaper. If the ownership or the facts change, or you abandon the name, you file a new statement or a Statement of Abandonment, which does require publication. If you stop using the name, filing a Statement of Abandonment frees it for others.

DBA vs LLC, EIN, and Trademark

A DBA is often confused with three other things. It is not a California LLC, which is a liability-protected entity filed with the state. It does not require a new EIN - a sole proprietor can use an existing EIN or Social Security number, and an LLC keeps its own EIN, because a DBA is just a name. And it is not a trademark: registering an FBN with a county gives no exclusive nationwide rights to the name. To confirm entity names statewide, use the California business entity search; separately, you may still need a local business license and a seller's permit.
