Abstract - By both effect and example, tax policy in the United States has a huge impact on the rest of the world. This paper explores five features of the American tax system that seem, from a British and European perspective, to be both especially peculiar and potentially instructive. These are the remarkably low overall level of taxation; the absence of a value-added tax (or any other major general national tax on consumption); the absence of any explicit interstate equalization; the marginal subsidization of low earnings under the earned income tax credit; and the fragmentation of power in policymaking, an important aspect of which is the role played by the Constitution.

INTRODUCTION

The tax policy pursued by the United States has powerful effects far beyond its borders. It has a direct impact on economic activity and well-being in other countries: changes in the tax treatment of savings or investment in the United States, for example, can induce significant capital flows, while ensuring and exploiting the availability to U.S. multinationals of the foreign tax credit on their repatriated profits is a major concern for many countries in designing their corporate taxes. The U.S. tax system is also widely looked to—rightly or wrongly—as an embodiment of best practice. This is true both of the broadest elements of tax strategy—as is evident in the widespread emulation of the base-broadening, rate-cutting strategy of the 1986 Tax Reform Act—and in the most detailed matters of tax design.
