  • Most businesses need at least a local business license or tax certificate from their city or county.
  • Using a name other than the owner’s legal name or the entity’s registered name requires a fictitious business name statement with the county.
  • Selling taxable goods requires a seller’s permit from the CDTFA, which is free.

Registrations depend on the structure, the location, and the kind of work. The list below covers the ones that come up most often and the agency that handles each. The state’s Office of the Small Business Advocate and local Small Business Development Centers help people identify which permits apply.

Fictitious business names

A fictitious business name statement is filed with the county where the business is based, generally within 40 days after starting to use the name. The statement must then be published in a local newspaper once a week for four weeks. It generally expires after five years. A county filing does not give trademark rights in the name.

Time frames

  • Fictitious business name statement: generally within 40 days of first using the name
  • Publication: once a week for 4 weeks
  • Statement expires: generally after 5 years

Common questions

Is a business name protected once it is registered?

A DBA filing or entity registration records the name, but it is not the same as a trademark. Federal trademark registration is handled by the U.S. Patent and Trademark Office, and state registration by the Secretary of State.
