Tuerck1 Executive Summary The U.S. corporate income tax is ripe for change – that’s what you will believe, anyway, if you follow the news as it relates to this subject. There is concern on the part of both major parties about the fact that the U.S. rate is the highest among OECD countries and that the U.S. policy of taxing corporations on a global, rather than a territorial, basis is causing trillions of dollars in corporate profits to be stranded in foreign banks. In this paper we describe how corporations and other business entities are taxed in the United States. We report statutory tax rates for the United States and other countries and discuss common U.S. corporate and business income tax avoidance schemes. We calculate an average effective tax rate for the United States and show how marginal effective tax rates affect investment decisions through their effects on the cost of capital. We report marginal effective tax rates for the United States and other countries and show how changes in statutory tax rates can affect investment, given different assumptions about the sensitivity of investment to changes in the cost of capital.
