The number of international tax disputes is constantly increasing. This is a logical consequence of the pressure that is exerted on the global tax system by a rise in the number of internationally active and mobile taxpayers and tax competition between states on the one hand. On the other hand, the implementation of measures to tackle base erosion and profit shifting (BEPS) by multinational enterprises already gives rise to further disputes and another increase of disputes might arise from the latest reforms of the international tax system, namely the Two-Pillar-Solution to address the tax challenges arising from the digitalisation of the economy. Against this background, the time is right for an institutionalised international tax dispute resolution mechanism that takes into account the interests of taxpayers, states, and the public and allows for a swift and binding resolution of international tax disputes ¬– exactly what this timely and thoroughgoing book offers. A comprehensive overview of existing international tax dispute resolution mechanisms – and an analysis of their procedural rules, advantages, and disadvantages – leads to a deeply informed proposal on how they can be further developed in a way that ensures greater fairness and equity for all stakeholders. Among the lines of conflict that characterise international tax disputes, the author sheds clear light on how improvements in the design of dispute resolution mechanisms may be found. This includes these questions: How should a dispute resolution mechanism be structured? Should there be a mandatory resolution if the states cannot agree? In which way should taxpayers participate in the procedure? Should agreements and decisions be published? Should there be an institution to administer the procedure? The book concludes with a draft convention that would implement the author’s suggestions. Tax lawyers and other tax professionals worldwide, as well as national tax authorities, will benefit greatly from this book. They will deepen their understanding of the variety of existing tax dispute resolution mechanisms and discover ways to strengthen them. Academics will find ample room to reflect on the key design elements of such mechanisms and how to improve them.

Bringing together global experts from diverse legal backgrounds, this comprehensive book offers a rigorous analysis of the complexity of resolving and preventing international tax disputes, covering arbitration, mediation, and dispute management. Presenting an authoritative overview of international tax disputes, this book will be indispensable to practitioners in corporate and international tax, controversy and dispute specialists, and investment arbitration lawyers.

Arbitration has been promoted as the future of tax dispute resolution in recent years in line with the increase in complexity of international tax law. This authoritative book presents existing legal rules on the matter, provides a review of the arguments in favour of tax arbitration, discusses the practical and legal challenges for its wide-spread adoption and compatibility with existing domestic and international norms. It also answers key questions for the practical implementation of a modern tax arbitration system.

International Tax Law is at a turning point. Increased tax transparency, the tackling of Base Erosion and Profit Shifting (BEPS), the reconstruction of the network of bilateral tax treaties, the renewed discussion about a fair and efficient allocation of taxing rights between States in a global, digitalized economy, and the bold push for minimum corporate taxation are some expressions of this shift. This new era also demonstrates the increased influence of international standard setters such as the OECD, the UN, and the EU. Each of these developments alone has the potential of being disruptive to the traditional world of international tax law, but together they have the potential to reshape the international tax system. The Oxford Handbook of International Tax Law provides a comprehensive exploration of these key issues which will shape the future of tax law. Divided into eight parts, this handbook traces the history of international tax law from its earliest days until the present, including reflections on the developments that have characterized the last one hundred years. The second section places tax law within the broader international context considering how it relates to public and private international law, as well as corporate, trade, and criminal law. Sections three and four consider key legal principles and issues such as regional tax treaty models, OECD dispute resolution, and transfer pricing versus formulary apportionment. Subsequent analysis places these issues within their European and cross-border contexts providing an assessment of the role of the ECJ, state aid, and cross-border VAT. Section seven broadens the scope of this analysis, asking how trends in recent major economies and regions have helped shape the current outlook. The final section considers emerging issues and the future of international tax law. With over sixty authors from 28 different countries, the Oxford Handbook of International Tax Law is an invaluable resource for scholars, academics, and practitioners alike.

An in-depth analysis of various aspects of multilateral cooperation in tax law Tax evasion and aggressive tax planning causing base erosion and profit shifting (BEPS) has been a widely discussed topic among academics and tax policy makers over the past decades. Increasing globalization and digitalization have contributed to the intensification of this issue in recent years. At the same time, states continue to largely insist on their sovereignty in the area of tax law. However, due to their cross-border nature, issues related to BEPS are shared problems among the states and can typically not be solved by a single nation. Therefore, multilateral cooperation represents an option to build a bridge between the states’ demand for sovereignty and the problems caused by BEPS. In this regard, the OECD, the UN, and the EU play an important role in introducing international tax standards in an attempt to effectively address tax evasion and aggressive tax planning in many ways. The interaction and cooperation between different international, supranational (EU), and regional organizations is an ongoing process. In this context, the topic "Multilateral Cooperation in Tax Law" was selected as the general topic for the master’s theses of the part-time 2021-23 class of the postgraduate LL.M. programme in International Tax Law at WU (Vienna University of Economics and Business). This volume aims to develop academic insights, provide practical guidance, and enable an in-depth analysis of various aspects of this topic. The book is divided into four parts. The first part deals with a general overview of the understanding of multilateral cooperation, the background that led to the need for multilateral cooperation and the different stakeholders that play a relevant role in it. While the chapters included in the second part focus on the most important developments on an international level (OECD and UN), the chapters encompassed in the third part analyse the multilateral cooperation initiatives of the EU. Finally, the chapters included in part four deal with selected issues related to multilateral cooperation in tax law, including mutual assistance and exchange of information, dispute resolution mechanisms, and measures in digitalized businesses.
