How to Get a Business License in Simi Valley: What You Need to Know (2026)
The Quick Version
Starting a business in Simi Valley, CA requires permits and registrations across multiple government layers — federal, state, Ventura County (county), and city. The primary city-level requirement is the Business Tax Certificate, issued by the Finance Department. Most businesses need 5 to 10 separate registrations, and the order you complete them matters because each step has dependencies on the ones before it.
Contact the Finance Department at 805-583-6700 for current requirements. More information is available at https://www.simivalley.org/departments/finance/business-license.
