California levies 7.25% statewide and San Francisco County adds a countywide district tax of 1.375%, bringing the countywide rate to 8.625%. No city or special district inside the county adds anything further, so 8.625% applies everywhere in the county. District taxes are approved by voters in individual cities and districts and do not follow county lines, so use the CDTFA address lookup for a specific location.
