When to choose a DBA alone: You are just starting out, want minimal cost and complexity, and are comfortable with personal liability.
When to choose an LLC: You want liability protection, plan to hire employees, seek credibility with clients, or anticipate significant business growth. The LLC provides legal separation between you and your business.
When to choose both: You form an LLC but want to operate under one or more additional business names. This is common for entrepreneurs running multiple brands or service lines under a single LLC.
Step-by-Step Filing Process
Step 1: Choose and verify your DBA name. Decide on the fictitious name you want to use. While there is no formal name-availability search for DBAs (unlike LLCs), you should search online and check the county clerk's records to avoid conflicts. You can search existing DBAs at your county clerk's website.
Step 2: Obtain the DBA form. Visit your county clerk's website and download the DBA application form, or pick one up in person. The form is typically called a "Statement of Fictitious Business Name" or "DBA Application."
Step 3: Complete the form. Fill in all required information: your legal name, the assumed business name, principal business address, type of business, and owner details. Sign the form under penalty of perjury. Some counties require notarization.
Step 4: File with the county clerk. Submit the completed form to your county clerk's office in person, by mail, or online. Pay the $26 filing fee (plus any county-specific fees). Keep a copy of the filed form for your records.
Step 5: Publish the notice. Contact a newspaper of general circulation in your county and request publication of your DBA notice. The newspaper will provide the notice language and handle publication. Publish once per week for four consecutive weeks, starting within 30 days of filing.
Step 6: Obtain the Affidavit of Publication. After the four-week publication period ends, the newspaper will provide you with an Affidavit of Publication. Keep this for your records (you do not file it with the county clerk, but it proves you complied with the publication requirement).
Step 7: Update your business records. Once your DBA is filed and published, update your business licenses, bank accounts, tax records, and any contracts to reflect the new name.
Common Mistakes to Avoid
Missing the publication deadline. Filing the DBA is only half the battle. You must publish the notice within 30 days of filing, or your DBA may be invalid. Many entrepreneurs file the DBA and forget about publication.
Failing to renew after five years. DBAs expire automatically after five years. If you do not renew, you lose the legal right to use that name. Set a calendar reminder well in advance.
Filing in the wrong county. You must file in the county where your principal place of business is located. Filing in the wrong county means your DBA is not valid in the county where you actually operate.
Using a P.O. box as your business address. California requires a street address, not a P.O. box. If you do not have a physical location, consider using a virtual office address or a coworking space.
Assuming a DBA provides liability protection. A DBA does not shield you from personal liability. Only an LLC, corporation, or other formal business entity provides that protection. If liability protection is important to you, form an LLC instead of (or in addition to) filing a DBA.
Not keeping proof of publication. Always keep the Affidavit of Publication from the newspaper. If someone challenges your right to use the name, this document proves you complied with California law.
Confusing DBA filing with LLC formation. A DBA is not the same as forming an LLC. An LLC is a separate legal entity filed with the California Secretary of State and provides liability protection. A DBA is a county-level registration that does not create a legal entity. You may need both.
Operating without a valid DBA. Do not begin business operations under an assumed name before your DBA is filed and published. Operating without a valid DBA violates California law and may result in penalties.
Providing incomplete or false information. Your DBA form must be accurate and complete. Providing false information under penalty of perjury can expose you to legal liability and invalidate your filing.
Neglecting to update your DBA. If your business address, ownership, or operating name changes, update your DBA filing with the county clerk. Failure to update can result in cancellation of your registration.
Key Takeaways
Filing a DBA in California is straightforward but requires attention to detail. The $26 filing fee is low, but the publication requirement—which costs $50–$150 and takes four weeks—is mandatory and often overlooked. You must file with your county clerk (not the state), publish in a local newspaper, and renew every five years.
If you want liability protection or plan significant growth, forming an LLC is a better long-term choice than relying on a DBA alone. An LLC provides legal separation from your business and costs only slightly more to set up. However, if you are a sole proprietor just starting out and want to operate under a business name with minimal cost, a DBA is the right choice.

Frequently Asked Questions
Q: Do I need a DBA if I form an LLC in California?
A: Only if you operate under a name different from your LLC's registered legal name. Your LLC's name must include "LLC," "L.L.C.," or "Limited Liability Company" per Cal. Corp. Code § 17701.08. If you want to do business under a different name, file a DBA with your county clerk.
Q: What happens if I don't publish my DBA notice in a newspaper?
A: Your DBA filing becomes invalid. You cannot legally use the assumed name, and you lose protection under California law. You must file a new DBA and complete the publication requirement to establish a valid registration.
Q: Can I file a DBA with the California Secretary of State?
A: No. DBAs are filed exclusively with your county clerk's office, not the state. The Secretary of State handles LLC and corporation filings only. Contact your county clerk directly for DBA filing procedures.
Q: How long does a DBA filing take in California?
A: County processing times vary, but most DBAs are approved within 1–2 weeks. Publication takes four weeks (once per week for four consecutive weeks). Plan for 5–6 weeks total from filing to completed publication.
Q: Can I use a P.O. box as my DBA business address?
A: No. California requires a street address where you conduct business or maintain records. If you don't have a physical location, use a virtual office address, coworking space, or your home address.
Q: What's the difference between a DBA and an LLC?
A: A DBA is a county-level registration of an assumed name with no liability protection. An LLC is a separate legal entity filed with the California Secretary of State that shields your personal assets from business liability. An LLC costs more to form but provides legal protection a DBA does not.
Q: Do I need to renew my DBA in California?
A: Yes. DBAs must be renewed every five years. The renewal fee is $26, plus newspaper publication costs. If you miss the renewal deadline, your DBA expires and you lose the legal right to use that name.
Q: Can I file multiple DBA names at once?
A: Yes, in most California counties. You can file multiple assumed names on a single application or file separate applications. Check your county clerk's requirements, as procedures vary by county. Each name may require a separate $26 fee.
Q: Do I need a business license in addition to a DBA?
A: Yes. A DBA filing is separate from a business license. California requires you to obtain a business license from your city or county in addition to filing your DBA with the county clerk. Contact your local city or county business tax office for licensing requirements.
