Busted! Clinton’s Avoided Federal Taxes in 2014, Created Shell Companies. illary Clinton is on record for a massive increase in the Estate Tax. It is no wonder then, that she has her personal estate and the Clinton Foundation well protected. Using tax shelters and shell companies, everything is as well protected as the upper 1% can afford. Never mind that this os the same sort of behavior that she has criticized Donald Trump for. I guess she is not into paying her fair share after all.
