Income, Gift and Estate Taxes: Tapp prefers a tax whose base is the amount of
money spent by an individual (that measures the goods and services she or he enjoys) then
a tax whose base is the amount of money received. Therefore, so long as the receipt of
money is used to assess a tax, Tapp's principles require it to be levied without regard to
the personal circumstances leading to that receipt: An Income Tax on money received for
work, a Gift tax on money received as a gift, and an Estate Tax on money received as an
inheritance.
