TAX INCIDENCE, TAX BURDEN, AND TAX SHIFTING:
WHO REALLY PAYS THE TAX?
EXECUTIVE SUMMARY
The current tax system imposes heavier taxes on income used for saving and investment, and
on the formation of human capital, than on income used for consumption. These tax disincentives
to save and invest, to work and take risks have consequences. They lead people to under-save and
over-consume, and to work less and play more. These adverse effects strongly urge us to dispose
of the current income tax structure and replace it with a flat rate tax that is neutral in its treatment
of saving and consumption. A tax system that is saving-consumption neutral would lead to a
significant increase in income across the board.
The tax biases against saving and investment and the current system's steeply graduated tax rate
structure were introduced for the purpose of improving social equity. It has been assumed that the
added layers of tax on income used for capital formation would do little economic damage, would
harm only the wealthy, and would provide significant income redistribution. It has become apparent,
however, that most of the taxes that seem to fall on those who supply physical capital, intellectual
capital, or special talents to the production process may actually be shifted to ordinary workers and
lower income retirees in the form of reduced pre-tax and after-tax incomes.
The political battles over proposed tax changes often turn on the question of who would gain
and who would lose. Answers to such questions are supposedly presented in so-called burden
tables prepared by the Treasury, the Joint Committee on Taxation, the Congressional Budget Office,
and tax researchers. The adverse economic consequences of non-neutral taxation and graduated tax
rates, and the resulting adverse impact on social equity, are not displayed in the burden tables.
With bad information, the public and the Congress are left with a bad tax system and a sub-optimal
economy.
The burden tables claim to show the distribution of the tax burden across taxpayers or
households of varying income levels. In fact, the tables try only to show the initial incidence of a
tax or a tax change on the after-tax incomes of those assumed to pay it. They do not examine
