The cash-flow tax has been proposed as an alternative to the corporate
income tax on grounds that it would define the tax base more clearly
and more simply in the face of widespread departures from the comprehe
nsive income tax of actual practice. The cash-flow tax, and its varian
ts, would require careful design. Simplicity may prove elusive because
of anticipated administrative problems related to tax avoidance and e
vasion through transfer pricing, to inflation adjustments, and to inco
mpatibility with existing international tax regimes. Thus, the tax rem
ains theoretically attractive but difficult to implement.
