Quick Reference
Sales Tax: Lease vs Buy
Lease: Sales tax on each monthly payment (not total vehicle value)
California taxes lease payments monthly at your local sales tax rate. Effective rate on a $40K car leased 36 months: ~3% of total payments.
Buy: Sales tax on full purchase price upfront — 7.25%-10.75%

CA leases typically 10K, 12K, or 15K miles/year. Excess mileage charged at lease end: $0.15-$0.30/mile.
End-of-Lease Buyout
Yes — buyout at residual value; CA buyer pays full sales tax
CA lease end: buy at residual value. WARNING: you pay full sales tax on residual price even though you already paid tax during the lease.
