The Business Tax Certificate is the license
The Office of the City Treasurer issues the Business Tax Certificate to every person conducting business in the city, including home-based businesses and independent contractors. The application is filed with the city, the certificate renews annually, and the business tax for most businesses is based on the number of employees, with separate rate schedules for certain classifications. Home-based businesses also clear the city's home occupation rules as part of setup.
The state layer
California adds the layers our California business license page covers in full: entity registration with the Secretary of State, the statewide franchise tax obligations, a seller's permit from the California Department of Tax and Fee Administration for any taxable sales, and state industry licenses, contractors through the CSLB prominent among them. Fictitious business names in California file at the county level, with the San Diego County Clerk handling filings and publication requirements.
Activity permits on top
San Diego requires police permits for a list of regulated activities, alarm businesses, secondhand dealers, massage establishments, and similar categories, and the county's Department of Environmental Health and Quality permits food establishments. Alcohol runs through the state ABC with local zoning conditions, and short-term rentals carry their own city license. If your activity is regulated, the Business Tax Certificate alone is not enough.
The multi-city county
The City of San Diego is one of 18 cities in San Diego County, and each licenses separately: a business in Chula Vista, Oceanside, or Carlsbad registers there, not with San Diego. Businesses with fixed locations in several cities commonly hold several certificates, and service companies working countywide should confirm which cities' registration thresholds their activity crosses.
The California state layer
City requirements sit on top of California's state-level rules: entity registration, tax permits, and industry licenses. Check both layers together.
California business license requirementsFrequently asked questions
How much does a San Diego business license cost?

Do freelancers in San Diego need a Business Tax Certificate?
Yes. The requirement covers anyone conducting business in the city, including independent contractors and home-based freelancers, who register within 15 days of starting business and renew annually.

No. The Business Tax Certificate is the City of San Diego registration. State obligations, entity filings, the CDTFA seller's permit, and industry licenses, are separate, and our California business license guide covers that layer.
