The California sales tax rate you pay is the 7.25% statewide base (6.00% state + 1.25% mandatory local) plus whatever district taxes voters have approved where the sale is delivered — which is why the real rate runs from 7.25% to roughly 10.75% depending on the address. District rates change every quarter somewhere in the state; the latest round took effect April 1, 2026 (CDTFA Special Notice L-1022), including Santa Clara County’s jump to 9.750%. Always confirm a specific address with the CDTFA rate lookup.
