The last time I looked, biz were owned by people. More important, biz expenses, such as taxes, are paid by people too. As a result, that distinction between "biz" and "people" doesn't make sense. Prop 13 limited the tax increases paid by people due to property value changes.
> stated that the property tax of a piece of land would be fixed at 1975 levels with a maximum of a 2% increase each
As I pointed out, that's wrong. There is a reassessment on on sale. My "prop 13" basis was set when I bought my house, decades after 1975. (My parent's basis, on the other hand, was set in 1975.) That's why my property taxes went up last year even though my "if I sold" value went down. (They'll go up next year too.)
That's why CA's property tax revenues are roughly stable.
I note that CA's income tax collection is incredibly variable, in part because so much is paid by the folks at the top.
