CA Personal Property Tax:

In California, all real property is taxed based on the fair-market value, and property taxes are collected locally.

Odd Tax Fact:

A "jock tax" is a special income tax levied on traveling athletes, entertainers, and other nonresident performers who worked in the state at some point during the year. There are now "jock taxes" in more than 40 states, but the very first state to levy such a tax was California. The tax was originally levied in 1991, just in time to tax Michael Jordan's income after the Chicago Bulls beat the LA Lakers in the NBA finals.
