Traditional economic theory holds that a business cash-flow tax is superior to a business income tax because it is more efficient and progressive. But much of the literature espousing this view does not explicitly specify the full range of assumptions underlying these claims, let alone explore and empirically justify them. This paper summarizes 11 assumptions underlying the traditional view and considers how well supported they are empirically and as a matter of political economy. It concludes that when each assumption is examined closely, the case for a cash-flow tax over a business income tax becomes considerably shakier and may well collapse.
