Abstract
If there is fundamental U.S. international income tax reform, regardless of the reform option chosen, the United States must decide how to handle the $2.4 trillion to $2.6 trillion of previously untaxed foreign income accumulated by U.S. multinational corporations. In this report, Fleming, Peroni, and Shay argue that the proper approach is to treat the income as a subpart F inclusion in the year before the effective date of fundamental reform and to tax it at regular rates with an option to make the payments in installments that bear market-rate interest. The authors explain why the case for a low or deferred tax on this income is inferior to the case for full immediate taxation.

Abstract
Reform of the U.S. international income taxation system has been a hotly debated topic for many years. The principal competing alternatives are a territorial or exemption system and a worldwide system. For reasons summarized in this article, we favor worldwide taxation if it is real worldwide taxation – i.e., a non-deferred U.S. tax is imposed on all foreign income of U.S. residents at the time the income in earned. This approach is not acceptable, however, unless the resulting double taxation is alleviated. The longstanding U.S. approach for handling the international double taxation problem is a foreign tax credit limited to the U.S. levy on the taxpayer’s foreign income. Indeed, the foreign tax credit is an essential element of the case for worldwide taxation. Moreover, territorial systems often apply worldwide taxation with a foreign tax credit to all income of resident individuals plus the passive income and tax haven income of resident corporations. Thus, the foreign tax credit is actually an important feature of many territorial systems. The foreign tax credit has, however, been subjected to sharp criticisms and Professor Daniel Shaviro has recently proposed replacing the credit with a combination of a deduction for foreign taxes and a reduced U.S. tax rate on foreign income. In this article, we respond to the criticisms and argue that the foreign tax credit is a robust and effective device. Furthermore, we respectfully explain why Professor Shaviro’s proposal is not an adequate substitute. We also explore an overlooked aspect of the foreign tax credit – its role as an allocator of the international tax base between residence and source countries – and we explain the credit’s effectiveness in carrying out this role. Nevertheless, we point out that the credit merits only two cheers because it goes beyond the requirements of the ability-to-pay principle that underlies use of an income base for imposing tax (instead of a consumption base). On balance, however, the credit is the preferred approach for mitigating international double taxation of income.

Abstract
The taxation of extractive industries exploiting oil, gas, or minerals is usually treated as a sovereign, national policy and administration issue. This book offers a uniquely comprehensive overview of the theory and practice involved in designing policies on the international aspects of fiscal regimes for these industries, with a particular focus on developing and emerging economies. International Taxation and the Extractive Industries addresses key topics that are not frequently covered in the literature, such as the geo-political implications of cross-border pipelines and the legal implications of mining contracts and regional financial obligations. The contributors, all of whom are leading researchers with experience of working with governments and companies on these issues, present an authoritative collection of chapters. The volume reviews international tax rules, covering both developments in the G20-OECD project on ’Base Erosion and Profit Shifting’ and more radical proposals, identifying core challenges in the extractives sector. This book should become a core resource for both scholars and practitioners. It will also appeal to those interested in international tax issues more widely and those who study environmental economics, macroeconomics and development economics.

Abstract
Continued tax-motivated inversions of U.S. corporations into foreign corporations highlight the systemic tax advantages that a foreign-owned U.S. corporation has over a U.S.-owned corporation in avoiding U.S. corporate tax on U.S. business income. In the absence of congressional action, this article emphasizes the need for the Treasury to further reduce U.S. tax incentives for inversions and other foreign acquisitions of U.S. corporations. The two most important of the tax incentives are earnings stripping and the ability to use, directly or indirectly, a U.S. group’s unrepatriated foreign earnings for the benefit of shareholders of the foreign parent corporation without incurring current U.S. income tax. These tax advantages will not be meaningfully reduced by any plausible lowering of the top U.S. corporate tax rate. Moreover, earnings stripping would be exacerbated by adoption of a territorial system. Treasury should use the administrative authority Congress delegated to it under Code sections 385 and 956 to restrict these foreign parent tax advantages and counter renewed market pressure on U.S. groups to engage in this form of tax avoidance. Treasury should employ existing anti-abuse regulations to address use of unrepatriated CFC earnings to benefit foreign parent groups.

Abstract
Research and development (R&D) activity has long held a privileged place in the U.S. income tax system and in policy debates. The premises for R&D tax incentives, however, are grounded in theory regarding a market failure for investment in R&D that does not align well with the target of U.S. R&D tax incentives. Moreover, factors contributing to innovation are now understood to include, in addition to R&D, other “knowledge-based capital” (KBC), investment in training and other human capital development, organizational processes, computer software, and architectural and engineering designs. The combination of existing R&D tax incentives, income shifting, and deferral of foreign income from U.S. tax, with intellectual property protection for successful R&D, result a poorly designed mix of overlapping benefits only loosely related to fostering innovation. Proposed “innovation box” tax incentives would add to the incoherence of the existing incentives. This article calls for a re-examination of U.S. R&D tax incentives under a framework that critically examines the scope of tax incentives and how they fit into an overall U.S. R&D and innovation incentive regime. The framework requires an evaluation whether R&D tax incentives address market failure or other nontax objectives, whether tax incentives are designed to efficiently achieve those objectives, and whether regulatory or direct expenditure alternatives would be more effective in achieving those objectives.

Abstract
The United States has a worldwide system that taxes the dividends its resident multinational corporations receive from their foreign affiliates, while most other countries have territorial systems that exempt these dividends. This report examines the experience of four countries – two with long-standing territorial systems and two that have recently eliminated taxation of repatriated dividends. We find that the reasons for maintaining or introducing dividend exemption systems varied greatly among them and do not necessarily apply to the United States. Moreover, classification of tax systems as worldwide or territorial does not adequately capture differences in how countries tax foreign-source income.

Abstract
The 21st Century has seen unprecedented levels of corporate tax aggressiveness and avoidance. This article continues our exploration of second best international tax reforms that would protect the U.S. corporate tax base and have some likelihood of adoption. In this case, we consider how a U.S. minimum tax on foreign income earned by a controlled foreign corporation should be designed to protect the United States against erosion of its corporate income tax base and to combat tax competition by low-tax intermediary countries. In the authors’ view, a minimum tax should be an interim levy that preserves the residual U.S. tax on foreign income, as distinguished from a final minimum tax that partially eliminates the U.S. residual tax. An interim minimum tax would be a significant improvement over current law and would more effectively limit incentives to seek low-taxed foreign income while ameliorating pressure to retain excess earnings abroad. To achieve the objectives of such a minimum tax, corresponding changes should be made to the U.S. corporate resident definition, the source taxation of foreign MNCs, and the residence taxation of U.S. portfolio investors in foreign corporations to reduce tax advantages under current law for investments in foreign corporations. These changes would reduce tax advantages for foreign parent corporate groups and thereby further protect the U.S. tax base as well as reduce incentives for U.S. corporations to expatriate as a consequence of increased U.S. taxation of foreign income under an interim minimum tax.

Abstract
The term “corporate inversion” is used to identify several transactional forms by which U.S. resident corporations are converted into foreign corporations or into U.S. subsidiaries of foreign corporations. These transactions are currently a large concern to U.S. tax policy makers and a lively debate is in progress regarding the best way forward. From a tax standpoint, corporate inversions are driven by the triple objectives of (1) enabling inverting U.S. corporations to escape U.S. taxation of their foreign-source income, (2) enabling U.S. corporations to effectively repatriate foreign-source income without paying a U.S. tax on such income, and (3) enabling those U.S. corporations to move U.S.-source income out of the U.S. tax base by means of deductible expense payments — a tactic known as cross-border earnings stripping. In previous work, we have explained how the first two of these objectives could be forestalled if the definition of a U.S. domestic corporation were broadened to include a shareholder ownership test and if the U.S. international income tax system were changed into a real worldwide system. In this Article, we address ways to forestall the third objective by imposing limits on earnings stripping. Focusing on inversions, however, results in a view of earnings stripping that is far too narrow. A principal emphasis of this Article is that earnings stripping presents challenges to the U.S. tax base that are much broader than corporate inversions and so we have developed an analytical framework for identifying responses to the full menu of earnings stripping tactics employed by multinational enterprises (MNEs), of which inversions are only a part. That framework shows that deductions for interest payments on intra-MNE debt, which are the largest contributor to earnings stripping, are also the most vulnerable to criticism from a policy standpoint. Consequently, we examine various approaches to limiting earnings stripping interest deductions and conclude that the best promise lies in employing a proportionate allocation approach to distinguish between interest expenses that are deductible as real costs and interest expenses that should be nondeductible because they are costless foreign related party payments that do not effect a proper inter-nation income allocation. We conclude that distinguishing between properly deductible and properly nondeductible cross-border payments for services is much more difficult and requires reliance on transfer pricing law. Finally, this Article advances understanding of the proper taxation of royalties paid by a U.S. subsidiary to a foreign member of an MNE but concludes that the ultimate resolution of that issue requires further work. Most importantly, this article shows that cross-border earnings stripping is devastating to the tax bases of both worldwide and territorial international tax systems. Thus, action needs to be taken to curtail the use of earnings stripping to erode the U.S. tax base without waiting to resolve the controversy over whether the United States should adopt a territorial system or instead significantly strengthen its badly flawed worldwide system.

In this Editorial, the authors explain the context of this special issue of the Bulletin for International Taxation. The fundamental premise of the BEPS project is that a coordination of national responses to BEPS can both eliminate double non-taxation and protect against material unrelieved double taxation. The articles in this issue further a dialogue among tax policymakers, taxpayers, advisors and academics that is critical to achieve this objective.

Abstract
Perhaps surprisingly, this Article has shown that the debate over formulary apportionment is little more than an alternative path to the larger debate over worldwide taxation versus territorial taxation. The present U.S. international income tax regime for U.S. MNEs is an implicit, overly-generous, and incoherent quasi-territorial system that relies on residence rules, source rules, and the arm’s-length approach to apportion international business profits between domestic income that is currently taxable by the United States and foreign income that is effectively exempt, or nearly so, from U.S. taxation because of deferral and cross-crediting. This version of territoriality is quite ugly because it is highly complex and it imposes only modest restraints on the ability of U.S. MNEs to shift income out of the U.S. tax base to low-tax foreign countries. Four forms of explicit territoriality have been proposed as alternatives to the current U.S. system. The first is traditional territoriality, which relies on source rules and the arm’s-length approach to apportion international business profits between taxable domestic income and exempt foreign income. This is a simpler regime than the current U.S. system because it confers exemption directly rather than implicitly through deferral and cross-crediting. It does, however, preserve the capacity of taxpayers to shift income to low-tax foreign countries subject only to the modest restraint imposed by the arm’s-length approach. Most importantly, it is inconsistent with the principle of ability-to-pay and it provides a powerful incentive to locate business activity in low-tax foreign countries. The other three forms of territoriality that are currently part of the debate are three-factor, two-factor, and single-factor global formulary apportionment. Each of them is simpler than either the current U.S. system or traditional territoriality, but each of them leaves U.S. MNEs with considerable capacity to accomplish erosion of the U.S. tax base through income shifting and each of them shares the defects of traditional territoriality regarding inconsistency with the ability-to-pay principle and distortion of business activity. Thus, U.S. policy makers are left with a choice between a normatively flawed and distortive territoriality that imposes modest restraints on income shifting through the arm’s-length approach (i.e., both the current U.S. system of de facto territoriality and traditional territoriality) and a simpler but normatively flawed and distortive territoriality that still allows a substantial amount of income shifting (i.e., three-factor, two-factor, and single-factor global formulary apportionment). This unhappy dilemma can be avoided by adopting real worldwide taxation or, alternatively, by keeping the current regime while creating a Subpart F income category for low-taxed foreign income and insulating that category from cross-crediting with a separate foreign tax credit limitation basket. A more limited form of formulary apportionment then should be used for, and tailored to, particular forms of income, such as intangible income and global trading income, that present discrete taxation problems. Nevertheless, when such income is earned by a U.S. MNE, allocation of income to a foreign jurisdiction under this more limited form of formulary apportionment should not ipso facto result in the income being exempted from U.S. taxation.

Abstract
This article reviews proposals by House Ways and Means Committee Chairman Camp and Senator Mike Enzi to shift the United States from its current system of deferring taxation of active foreign income to a system that would exempt foreign business income from U.S. tax. (Neither proposal would materially affect the present U.S. system for taxing U.S.-source income.) The major contributions of the Camp Proposal lie in its recognition of the need to (i) make the treatment of foreign branches and foreign subsidiaries more neutral, and (ii) protect the U.S. tax base from excess interest deductions and the base-eroding incentives of very low foreign tax environments that stimulate U.S. income shifting. However, these improvements to current law would not justify changing to an exemption regime under the Camp Proposal in light of its many weaknesses, which include (but are not limited to) (i) material under-allocation of expenses to exempt foreign income, (ii) material loopholes in its anti-abuse rules for protecting the U.S. tax base, (iii) an apparent failure to tax gain upon transfers of appreciated assets into the exemption regime, (iv) foreign tax credit changes that would result in additional erosion of the U.S. tax base and (v) a misguided proposal for a reduced tax rate on royalties earned from foreign persons. The Enzi Proposal has similar weaknesses while lacking the strengths of the Camp Proposal. Our analysis of the Camp and Enzi Proposals highlights that U.S. international tax reform is integrally related to U.S. corporate, shareholder and business pass-through taxation. A full consideration of any international business taxation proposal must be in the context of the overall income tax regime within which the international rules must operate. Chairman Camp has promised a comprehensive tax reform proposal; and business and financial products elements have been put forward. However, a final evaluation of his international proposal must await release of a completed, integrated tax reform package, including final corporate and individual tax rates. Senator Enzi’s proposal is a stand-alone reform and apparently is intended for adoption irrespective whether the corporate tax rate is reduced or other tax reforms are enacted. In a recent article we articulated how a principled exemption system should be designed so as to protect the U.S tax base. It is possible to modify the Camp and Enzi Proposals to address their weaknesses in ways consistent with a principled exemption system. We recognize that such changes would make them unattractive to many in the multinational corporate community; however, that likely is true of any exemption system that would be a material improvement over current law. In our view, unless a shift to an exemption system would constitute a material improvement over current law, the likely revenue losses and transition costs of such a change would outweigh the benefits.

Abstract
This article springs from two concurrent phenomena. First, U.S. federal deficit spending projections indicate that any feasible deficit reduction plan will require substantial additional revenue. Second, the U.S. system for taxing foreign-source income is so badly flawed that if the United States were to adopt a principled exemption or territorial system under which eligible foreign source income is taxed at a zero rate, the fisc would actually gain revenue with which to ease the deficit problem. To realize its revenue raising potential, however, an exemption system will require the following characteristics (or comparable analogues): 1) A robust subject-to-tax requirement (to foreclose use of low-tax foreign regimes) and continued current taxation of passive and mobile income under an updated Subpart F regime; 2) Disqualification from exemption for royalties (including deemed royalties from a foreign branch), interest, services payments and other foreign-source items that do not bear a significant foreign tax; 3) Elimination of the current tax exemption for 50 percent of the income from U.S. export sales; 4) Allocation of domestic expenses to foreign-source income to protect the U.S. tax base from “deduction dumping” in a more realistic way than an inadequate 5 percent “haircut” and 5) A prohibition against deducting foreign losses from U.S.-source income. To the extent that an exemption system deviates from these five characteristics, it creates revenue transfers to a relatively small group of mostly prosperous U.S. multinational corporate taxpayers at a time when the Treasury is in distress. This ought not to be allowed unless the transfers can pass a rigorous cost/benefit test.

Abstract
This article argues that flat opposition to revenue increases has contributed to U.S. economic vulnerability and has had unintended effects, including contributing to increased deficits instead of smaller government. The article distinguishes fundamental income tax reform from raising revenues from tax expenditures and recommends that the Treasury Department spearhead fundamental income tax reform, within the context of an overall budget framework that includes revenue increases, and develop detailed proposals to make the individual and corporate income taxes fairer, simpler and more efficient.
