California Motor Vehicle Tax Laws & Regulations
When purchasing a car in California, understanding how your state assesses tax and regulates dealer fees ensures you never overpay at the dealership signing table. Primary legal authority is codified under Cal. Rev. & Tax. Code § 6012 & Cal. Veh. Code § 11713.1.
1. Sales Tax Assessment & Surtaxes
Under Cal. Rev. & Tax. Code § 6012 & Cal. Veh. Code § 11713.1, California imposes a 7.25% state base rate. City and county district taxes frequently increase total tax up to 10.75% (e.g. Los Angeles 9.50%, Alameda 10.25%).
