LA introduced a mansion sales tax.
Anywhere else?
My main issue with a marginal property tax is that the areas with high property values already have enough taxes generally for the things property tax covers.
Not sure at least in the US how feasible it would be to have a marginal property tax and the revenue go to the state and the Fed (or even the county's general fund in most places).
My guess is there's a 0% chance the marginal property tax could go to the Fed to reduce Federal income tax, and in most states, a low chance it could even go to the state, or even in most counties that it could go to the general fund instead of mostly to the local school district and local fire department (which are usually already funded adequately).
