How to Get a DBA in California: Filing, Publishing, and Renewal

To get a DBA in California, you register a Fictitious Business Name (FBN) with the Clerk-Recorder in the county where your business is based, then publish the statement in a local newspaper once a week for four consecutive weeks. You have 40 days from the date you start using the name to file with the county, and another 45 days after filing to get the first publication started.¹ Miss either step and you cannot enforce contracts or bring lawsuits under that name in California courts.²

Do You Actually Need a DBA

California requires an FBN filing any time a business operates under a name that does not include the owner’s real surname. A sole proprietor named Maria Lopez doing business as “Lopez Consulting” does not need one. “Coastal Consulting” does. The same test applies to partnerships, LLCs, and corporations: if the name you use with customers differs from the legal entity name registered with the California Secretary of State, you need to file.² A name that suggests additional owners beyond those actually involved also triggers the requirement, even if it contains an owner’s surname.

The 40-day clock starts the moment you begin transacting business under the fictitious name, not the day you pick the name or form the entity.¹

Step 1: File With the Right County

The FBN statement goes to the Clerk-Recorder in the county where your principal place of business is located.³ If you run things from your home in Orange County, that is where you file, even if your customers are mostly in San Francisco. You can file in additional counties voluntarily, but the principal-place filing is the one that satisfies the statute.

Businesses based entirely outside California that still transact business in the state file with the Sacramento County Clerk.³ This typically applies to out-of-state online sellers or consultants with California clients but no physical location in the state.

Check the Name First

Before you file, search the county’s FBN index to see whether anyone is already using the name you want. Each county keeps its own index, and most offer free online searches. The county Clerk-Recorder accepts filings without guaranteeing the name is unique, so two businesses in the same county can end up with similar or identical fictitious names.⁴ Also check the California Secretary of State’s business entity database, since your name could conflict with a registered corporation or LLC even without a matching FBN on file.

Step 2: Complete the Statement

The form is prescribed by state law and asks for specific information:⁵

The exact fictitious business name you will use on signs, invoices, and advertising.
The street address where the business operates. A P.O. box will not do.
Full legal names and residence addresses of every person involved, whether a sole proprietor, each general partner, or each member of a joint venture.
The business entity type: individual, general partnership, limited partnership, corporation, LLC, trust, or other recognized structure.
The date you first started doing business under the name, or a statement that you have not yet begun.

You sign a declaration that the statement is true and correct.

Notarized Affidavit of Identity

Every FBN statement in California must be accompanied by a notarized affidavit of identity, whether it is an original filing, a renewal, or a new statement triggered by a change. This came in under Senate Bill 1467 and applies statewide.⁶ You sign the affidavit in front of a notary, so plan the trip to the notary before you plan the trip to the Clerk-Recorder, especially if you intend to file by mail.

Step 3: Pay the Fee and Submit

Filing fees vary by county and generally run between $26 and $54 for a statement with one business name and one owner. Each additional owner or name on the same statement adds roughly $5 to $7.⁷⁸ Confirm the exact amount on your county’s website before you go.

Most counties accept filings in person, by mail, or through an online portal. In-person filing gets you a certified copy the same day, which matters if you want to open a bank account that week. Mail filings take longer and need a self-addressed stamped envelope for the return. Online portals, where offered, are usually the fastest route if you do not live near the county office.

Step 4: Publish the Statement in a Newspaper

Once the county accepts your filing, arrange for the statement to be published in a newspaper of general circulation in the same county. The publication runs once a week for four consecutive weeks, and the first publication must happen within 45 days of the filing date.⁹ Missing this deadline can invalidate the filing.

After the final week, the newspaper files an affidavit of publication with the county Clerk-Recorder. That affidavit must reach the county within 45 days of the last publication date.⁹ Most newspapers that handle legal notices will take care of this step, but follow up to make sure it gets done. Publication costs vary widely, usually somewhere between $40 and $120. Smaller community papers that specialize in legal notices tend to charge less than major daily papers.

Using Your DBA With a Bank and the IRS

One of the most practical reasons to file is that banks require a certified FBN statement before they will open a business account under your fictitious name. Walk in without it and you will be turned away. Banks will also ask for your EIN or Social Security number, government-issued photo ID, and any local business license. Partnerships should bring the partnership agreement, LLCs their articles of organization, and corporations their articles of incorporation. Call ahead to confirm, since requirements vary.

The DBA does not change your federal tax picture. You do not need a new EIN just because you filed a fictitious name. If you already have one for your sole proprietorship, LLC, or corporation, you keep using it.¹⁰ Sole proprietors without employees can keep using their Social Security number. Income earned under the fictitious name gets reported exactly the way income under your legal name does.

What a DBA Does Not Do

A fictitious business name filing lets you legally operate under a different name. That is the whole function. It does not create a new business entity, does not shield you from personal liability, and does not give you exclusive rights to the name beyond what common law already provides.¹¹

Sole proprietors and general partnerships operating under a DBA remain personally responsible for every debt and legal obligation the business incurs. If liability protection is the goal, forming an LLC or corporation is a separate filing with the California Secretary of State. The two filings serve different purposes, and one does not substitute for the other.

The DBA also gives you no trademark rights. Another business can use the same or a confusingly similar name, and your county filing will not stop them. Federal trademark registration through the USPTO provides a legal presumption of nationwide exclusive rights to the mark; a state-level filing only reaches that state’s borders.¹² If the name is central to your brand, treat trademark as a separate project.

Renewing, Updating, and Abandoning the Name

An FBN statement is valid for five years from the filing date.¹³ To keep the name active, file a renewal before that five-year mark. The renewal process mirrors the original filing: new statement, fee, publication. Letting it lapse means losing the ability to enforce contracts under the name until you refile.

Certain changes cause the existing statement to expire 40 days after the change, forcing a new filing within that window. These include a change in the business name, a change in the street address where the business operates, or the addition or removal of an owner.¹³ A change to an owner’s residence address is specifically exempt and does not require a new filing.¹⁴

If you stop doing business under the fictitious name before the five-year expiration, file a statement of abandonment with the same county Clerk-Recorder where the original was filed. The abandonment statement also has to be published in a newspaper once a week for four consecutive weeks, with an affidavit of publication returned to the county afterward.¹⁵ If the original is already more than five years old and was never renewed, no abandonment is needed; it has already expired on its own. Abandonment fees are typically lower than filing fees.
