The research aims at presenting a UT that would restore credibility in the international tax arena by providing fiscal predictability and certainty to MNEs, and ensuring appropriate taxation by all countries (specifically developing nations) of all “real” economic activity within their borders. Although this issue has been previously explored, there is currently a vacuum to be filled concerning a coherent and complete UT as an alternative to the current taxation of MNEs from a developing countries’ perspective. Specifically, there is a need for a major research and elaboration of a specific UT that would satisfy the legitimate concerns of developing countries while not alienating the developed world and MNEs. That is the goal of this Dissertation. The international tax regime was created in an effort to avoid situations where the same income was subject to double taxation due to the exclusive fact that it had a cross border character. However, sovereign tax laws and tax regimes have grown so different, and international economic activity has grown so large that the debate ought to shift from the exclusive legitimate need to avoid double taxation to the urgent imperative to prevent double non-taxation and other undue tax arbitrage schemes1 that are threatening the very existence and credibility of the international tax regime. The current debate2 in the international tax world about the 1 David Rosenbloom, International Tax Arbitrage and the International Tax System, 53 Tax L. Rev. 137 (1999). 2Avi-Yonah, Kimberly Clausing, and Michael Durst, Allocating Business Profits for Tax Purposes: A Proposal to Adopt a Formulary Profit Split. Michigan Law School: Public Law and Legal Theory Working Papers (2008). 5 inappropriateness of arm’s length standards and its disservice to tax authorities across the globe is opening a tremendous opportunity to reflect and design an international tax system that is fair to MNEs by providing them with fiscal certainty, and fair to all countries, particularly developing countries, by allowing them adequate taxation of economic activity through independent and sovereign tax policies. This research is a response to the current global outcry about the misfortunes of the international tax treatment of MNEs, largely based on the separate accounting arm’s length standard (“ALS”). Currently MNEs that operate in different countries have very complex and burdensome tax rules applicable to them. The economic realities of MNEs’ operations have shown completely irrelevant in the design of the applicable tax rules. MNEs have therefore proven extreme creativity in using tax rules to their advantage since these rules are not inspired and usually have no real impact on the economics of their transactions. The need to conduct a business in a foreign country in the form of a Permanent Establishment (“PE”) for example is very comparable, on a strict economic standpoint, to the regime of conducting the same business in the form of a Controlled Foreign Corporation (“CFC”). However, in the view of tax law, the not so economically relevant fact of choosing a PE or a CFC has tremendous fiscal consequences. The debate over “check the box” regime in the U.S. and its use abroad by U.S. MNEs is a telling example.3 The main focus of this research is twofold: on the one hand I intend to analyze the current ills of taxation of MNEs, their negative impact on tax authorities in developing countries specifically, 3 Steven Dean, Attractive Complexity: Tax Deregulation, the Check the Box Election, and the Future of Tax Simplification, 34 Hofstra L. Rev. 405 (2005). 6 and the urgent need for a different approach. On the other hand, I intend to design and structure a proposal for a better way of taxing MNEs. Through this structure, I intend to align international tax rules to economic realities. The UT proposed in this research would provide for equitable taxation of MNEs in every jurisdiction they operate in, specifically, in the developing world. The research therefore aims at providing an in-depth study and explanation of the current unsustainable international tax regime, its weaknesses and unfairness in taxing MNEs; then the construction of a new and better structure to approaching and taxing MNEs: the UT. First, the discussion of the ills of the current system, focusing specifically on the developing countries, would require empirical research of current specific international tax policies in selected sample countries. Also, the design of a new structure would require answering several questions including: what is a UT (an agreement on definitions of Unitary Business, Combined Reporting and Formulary Apportionment)?
