CA state law Underneath, California law still applies. County documentary transfer tax: A county may tax a sale over $100 at $0.55 for each $500 of value ($1.10 per $1,000), not counting liens that remain on the property (Rev. & Tax. Code § 11911(a)). City share of the tax: A city may impose half the county rate ($0.55 per $1,000); the county then credits the city tax against its own, so the combined standard rate stays $1.10 per $1,000 (Rev. & Tax. Code § 11931). California rules for buying and selling — the full state rule →
