Start & manage a business

California entity filings, seller permits, sales tax and professional licensing.

Before you start

  • Choose your actual entity or profession and location; use the official instructions before entering private information.
  • Check city/county business licensing and county fictitious business names separately. This statewide guide does not complete every local workflow.
