How California Sales Tax Works
1) Statewide Base Rate
California has a statewide base sales and use tax rate of 7.25%. That is the starting point, but it is not always the final rate paid at checkout.
2) District Taxes by City and County
Many areas add district taxes on top of the base rate. That means your total combined sales tax can be higher depending on where the sale takes place (or where the item is delivered in certain transactions).
3) Taxable vs. Non-Taxable Items
Most tangible goods are taxable. However, California tax rules include exceptions and special cases. Some food products, certain medical goods, and specific service-related charges may be treated differently.
Because rules vary, always confirm details with current California Department of Tax and Fee Administration guidance for business decisions.
