The power of a country to freely design its tax system is generally understood to be an integral feature of sovereignty. However, as an inevitable result of globalization and income mobility, one country’s exercise of tax sovereignty often overlaps, interferes with, or even impedes that of another. In this collection of essays, internationally respected practitioners and academics reveal how the OECD’s Base Erosion and Pro t Shifting (BEPS) initiative, although a major step in the right direction, is insuf cient to resolve the tax sovereignty paradox. Each contribution deals with different facets of a single topic: How tax sovereignty is shaped in a post ,BEPS world. The contributors provide in ,depth analysis of such relevant issues as the following: hy multilateral cooperation and soft law consensus are the preferred solutions to a loss of autonomy over national tax policy; – how digital commerce has upended traditional notions of source and residence; – why residence and source continue to be the two essential building blocks of tax sovereignty and the backbone of the international tax system; – how developing countries can take advantage of the new international tax architecture to ensure that their voices are truly shaping the standards; and – transfer pricing reform. Collectively, the authors provide an authoritative commentary on the necessary preconditions for exercising the power to tax in today’s world. Their perspectives and recommendations will prove of great value to all policymakers, legislators, practitioners, and academics in the international taxation arena.

The Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (MLI) is the most forceful multilateral initiative to coordinate tax regimes on a worldwide basis since the dawn of modern income taxation over a century ago. This book evaluates two radically opposed viewpoints on the convention—a momentous and revolutionary paradigm shift versus a mechanism that merely continues an ongoing flow of limited policy coordination—with detailed investigations that bring to life the hopes and the realities of the current era of multilateral tax cooperation. Bringing together authors from national jurisdictions across the globe to scrutinize the MLI and its likely future ramifications, the book provides in-depth commentary and analysis in the following sequence: first, a comprehensive discussion of the design and goals of the MLI as a treaty and an institutional framework; second, an overview of the structure of the convention and its take-up across the globe to date; and third, the substantive implementation of the MLI with a wide range of country reports. Practice areas covered include tax law, international law, and international relations. The legal workings and implications of the MLI might still seem mysterious to those whose daily work is impacted by it, and there is as yet little jurisprudence regarding its legal nature or ultimate effect on the bilateral treaties coming within its scope. For these reasons, this pathbreaking book will be warmly welcomed by in-house counsel and law firms advising cross-border investors and firms; nongovernmental organizations involved in policy analysis and issue advocacy; researchers working on technical areas of international tax law; and lawyers interested in international policymaking, including the creation and diffusion of consensus-based fiscal and related regulatory norms across jurisdictions of differing development levels.

This report presents studies and data available regarding the existence and magnitude of base erosion and profit shifting (BEPS), and contains an overview of global developments that have an impact on corporate tax matters.

Recent tax developments aimed at mitigating the possibilities of base erosion and profit shifting are expected to increase the importance and popularity of tax incentives. This is due to the fact that states will want to remain competitive on the international stage and multinational enterprises will look for other opportunities to minimize their tax liabilities.0This book seeks to answer the following essential questions, from both a practical and an academic perspective:0- Will tax incentives be the 21st century tool for tax planning structures?0- Will states need to introduce more tax incentives in the future in order to be more competitive?0- What are the effects of the anti-abuse measures adopted by the EU Member States and recommended by the OECD on tax incentives?0- What are the challenges of securing the use of tax incentives?0- What new tax policy challenges will tax incentives bring about? 00This book answers these questions by analysing selected tax incentives that are commonly promoted by both developed and developing states, particularly those tax incentives that are of relevance to corporate income taxation.

This book discusses which is the most appropriate tax dimension to best manage the new horizons of the global and digital economy. In this perspective, the efficiency of the main models is examined and two fundamental proposals are put forth: the first one aims at a coordination of the Destination-Based approach with the role of some specific digital assets, such as user data; the second one is a framework for a possible futuristic tax phenomenon all internal to the world of the internet and not linked to traditional territorial States. The compliance of these models with the constitutional principles that western democratic systems have affirmed over time in matters of taxation is then analyzed with particular regard to legal certainty, consent to taxation and to the re-distributive function of taxes. A specific evaluation of the role of the European Union is carried out and the jurisprudence on financial interests of the Union and on State aids is analyzed and tackled in light of the Treaty on the Functioning of the European Union and of the tax sovereignty of member States. The conclusion is that the model of the organization with a general political purpose, from which modern States take their inspiration, appears unfailing for a tax project that would focus on the good and the growth of the person and of the social aggregations in which everyone lives. A model that therefore deserves to be safeguarded, although with new methods and instruments, starting from a Destination-Based Asset-Coordinated approach, in the Third Millennium. The book will be of interest to researchers and academics in international tax law, constitutional law and in political science.

Explains why perfecting, rather than curbing, interstate competition would make international taxation both more efficient and more just.
