Frequently Asked Questions
Why does the default rate not match my receipt?
California sales tax depends on your exact address. Cities and counties add district taxes on top of the statewide base, so the combined rate changes by location.
Where can I find my exact California sales tax rate?
Use the California Department of Tax and Fee Administration online tools or ask the retailer for the rate applied at your delivery or pickup location.
