USA / CALIFORNIA SALES TAX RULES:

California is a origin-based sales tax state, which means sales tax rates are determined by the location of the vendor, not by the location of the buyer.
The origin-based method of determining sales tax is less complicated for vendors than destination-based sales tax, because all in-state buyers are charged the same sales tax rate regardless of their location.
