By calling it an inheritance “tax” many people are fooled. (head up the a$$)
It’s not a tax. It’s confiscation.
So how do the real wealthy get away from this. Answer: residual trusts. They give there wealth away... due in 10-20 years. The family gets the interest/cap gains tax free until the bill is due. Results in a 5-15% inheritance tax. Slick, but only available to those with tax attorneys.
