Under the BEPS Action 5 minimum standard, members of the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting (BEPS) have committed to counter harmful tax practices with a focus on improving transparency. One part of the Action 5 minimum standard is the transparency framework for compulsory spontaneous exchange of information on certain tax rulings.

BEPS Action 5 is one of the four minimum standards which all members of the OECD/G20 Inclusive Framework on BEPS have committed to implement. One part of the Action 5 minimum standard is the transparency framework for compulsory spontaneous exchange of information on certain tax rulings which, in the absence of transparency, could give rise to BEPS concerns.

Under the BEPS Action 5 minimum standard, members of the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting (BEPS) have committed to counter harmful tax practices with a focus on improving transparency. This report reflects the outcome of the seventh annual peer review of the implementation of the Action 5 minimum standard.

Tax competition in the form of harmful tax practices can distort trade and investment patterns, erode national tax bases and shift part of the tax burden onto less mobile tax bases. The Report emphasises that governments must intensify their cooperative actions to curb harmful tax practices.

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.

In light of the significant transformations affecting international tax in recent years, this book offers in-depth examinations on a series of key issues on the taxation of cross-border transactions. Craig Elliffe brings together a wealth of acclaimed legal academics to consider how the Inclusive Framework (IF) is responding to the ways in which highly digitalised businesses operate.

This comprehensive book adopts a nuanced yet straightforward approach to analysing the complex phenomenon of international tax competition. Using the ongoing international efforts of the Organisation for Economic Co-operation and Development (OECD) and the European Union (EU) as a basis for its analysis, it explores the mixed effects of tax competition and offers an effective approach that takes account of the asymmetrical global context.

Preferential regimes continue to be a key pressure area. Current concerns are primarily about preferential regimes which can be used for artificial profit shifting and about a lack of transparency in connection with certain rulings. The report sets out an agreed methodology to assess whether there is substantial activity. In the context of IP regimes such as patent boxes, agreement was reached on the nexus approach which uses expenditures as a proxy for substantial activity and ensures that taxpayers can only benefit from IP regimes where they engaged in research and development and incurred actual expenditures on such activities. The same principle can also be applied to other preferential regimes so that such regimes are found to require substantial activity where the taxpayer undertook the core income generating activities. In the area of transparency, a framework has been agreed for the compulsory spontaneous exchange of information on rulings that could give rise to BEPS concerns in the absence of such exchange. The results of the application of the existing factors applied by the FHTP, and the elaborated substantial activity and transparency factors, to a number of preferential regimes are included in this report.
