California Secretary of State (entity formation) / California Department of Tax and Fee Administration - CDTFA (seller's permit) / City/County for local business licenses
Step by Step
How to do it
Determine your business structure: sole proprietor, LLC, corporation, partnership
Register your business entity with the California Secretary of State (for LLCs and corporations) at sos.ca.gov/business-programs - file online via BizFile California
Obtain an EIN (Employer Identification Number) from the IRS at irs.gov if forming an entity, hiring employees, or operating as a partnership
Register with the California Department of Tax and Fee Administration (CDTFA) for a California Seller's Permit if you sell or lease tangible personal property - free to register at cdtfa.ca.gov; required to collect and remit California sales tax
Register with the California Employment Development Department (EDD) if you have employees - payroll tax registration at edd.ca.gov
Obtain a local business license from your city and/or county - almost all California cities require a local business license (called a business tax certificate in some jurisdictions); unincorporated county areas may also require a county business license
Check for industry-specific professional licenses: contractors (CSLB), health professionals, real estate agents, cosmetologists, and many others require state professional licenses through the relevant California licensing board
Renew entity biennial report with Secretary of State; renew local license per your city's schedule
