Compared to what? California is not exactly known as tax heaven.
Anyone who lives here knows perfectly well that their neighbor who bought a house in the 80s has a property tax bill 10x lower than theirs - actually I live next to several car dealerships who’d pay less than I would if I could afford a house here. That’s the power of Prop 13.
Besides that, CA residents are probably getting a tax refund this year because the state has a budget surplus.
I am sure California tax rate is under 70%, but I find it highly non transparent and unpredictable.
