Net worth, in the general sense anyway, doesn’t get taxed. This is one of the ways billionaires can pay so little taxes. Outside of things like property tax, you don’t pay tax on something like a house.
If we are talking straight net worth and not income, then I paid ~10% in federal taxes last year. But again that’s not really a fair comparison as we aren’t taxed on net worth but income.
The tax system is fucked and needs a serious overhaul.
