Questions Frequentes
How does ZIP code affect CA sales tax?
Each ZIP maps to a specific tax district combination. District taxes (county, city, transit, special purpose) vary by location. Two ZIP codes in the same city may have different rates if they fall in different special districts.
Why does my ZIP rate differ from the city rate?
Some areas have special tax districts (Mello-Roos, transit, hospital) that only apply to specific ZIP codes within a city. The CDTFA website has the definitive rate lookup by address.
What is the highest CA ZIP code rate?
Some ZIPs in LA County and Alameda County reach 10.75% combined. The lowest possible is the 7.25% base in areas with zero district additions.
Is this the same rate used for online orders?
Online orders use the delivery address rate. If you ship to a 10.25% ZIP, that rate applies regardless of where the seller is located.
How often do ZIP-level rates change?
Quarterly. New voter-approved district taxes take effect on January 1, April 1, July 1, or October 1. CDTFA publishes updated rate files each quarter.
