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.

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.

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.
