Harnessing the Costs of International Tax Arbitrage

Professor Adam H. Rosenzweig (from Washington University) has postes Harnessing the Costs of International Tax Arbitrage, 26 Va. Tax Rev. 555 (2007). Here is the abstract:

The issue of international tax arbitrage has proven a difficult and intractable one. Rather than try to minimize costs of the arbitrage or prevent “abuse” of the laws of a particular regime, the United States should also consider affirmatively bearing some of the costs of the international tax arbitrage transaction to further the policy of international vertical equity and shift the incentives in the worldwide regime that led to the rise of the arbitrage in the first place.

Harnessing the costs of international tax arbitrage transactions will not always be the appropriate response to each particular arbitrage transaction. Depending on the circumstances, the traditional responses may be sufficient, a fundamental change to the underlying United States domestic tax law may be appropriate or a worldwide consensus on harmonization in a particular area may arise. Harnessing the costs of the international tax arbitrage should be considered, however, when such responses prove inadequate. At a minimum, in adopting such an approach the United States would provide some level of subsidy for investment in developing countries at little to no cost to the current international tax regime. At best, however, harnessing the costs of international tax arbitrage could place of the issue of international tax arbitrage back on the international scene, restart stalled international tax discussions and potentially move towards a greater worldwide consensus, not only on the international tax arbitrage itself but on the larger issue of the role of international vertical equity in the worldwide tax regime. In a second-best world, United States unilateral action in harnessing the costs of international tax arbitrage may be the first step towards a first-best solution.
