California Sales Tax FAQ

What is the California state sales tax rate?

The statewide base rate is 7.25%, which already includes a mandatory local component. District taxes stack on top, so combined rates in some cities exceed 10%.

Why do two nearby California addresses have different rates?

Voter-approved district taxes apply by district boundaries, not city limits. Two addresses a few blocks apart can sit in different districts, so use the CDTFA address lookup for delivered sales.

Do district taxes apply where I ship or where I am located?

District taxes are generally destination-based — they follow where the merchandise is delivered — while the statewide portion follows different rules. The CDTFA publishes guidance for mixed situations.

Is this calculator tax advice?

No. It is a math helper only. Confirm the correct combined rate for a specific address with the CDTFA or a qualified professional.
