California Car Sales Tax Calculator – Fast, Free & Accurate

What Is California Car Sales Tax?

California has a statewide base sales tax of 7.25%. On top of that, each county or city can add its own district tax. This means the total rate you pay depends on where you register the car.

For example:

• Los Angeles County: 9.5%
• San Diego County: 7.75%
• San Francisco County: 8.625%
• Santa Clara County: 9.375%

So, two people buying the same $30,000 car could owe different sales tax amounts depending on their location.
