Carsten Wendt analyses the necessity, the concept as well as potential advantages and effects of a common tax base for multinational enterprises in the European Union. He addresses important issues concerning a common tax base, such as the definition of the consolidated group, the technique and scope of consolidation and the formula used to allocate the consolidated tax base among the involved member states.

This consolidated version of the OECD Transfer Pricing Guidelines includes the revised guidance on safe harbours adopted in 2013, as well as the recent amendments made by the Reports on Actions 8-10 and 13 of the BEPS Actions Plan and conforming changes to Chapter IX.

In a global economy where multinational enterprises (MNEs) play a prominent role, governments need to ensure that the taxable profits of MNEs are not artificially shifted out of their jurisdiction and that the tax base reported by MNEs in their country reflects the economic activity undertaken therein. For taxpayers, it is essential to limit the risks of economic double taxation.

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.

Following each Member State's need to rebuild a strong and stable economy after the 2007 financial crisis, the European Union (EU) has developed a robust new transparency framework with binding anti-abuse measures and stronger instruments to challenge external threats of base erosion. This is the first and only book to provide a complete detailed analysis of the Anti-Tax Avoidance Package and other recent and ongoing European actions taken in direct taxation. With contributions from both prominent tax academics and Spain's delegates to the European meetings where these rules are debated and promulgated, the book covers such issues and topics as the following: – the development of the EU Strategy towards Aggressive Tax Planning; – recent tax-related jurisprudence of the European Court of Justice; – the Anti-Tax Avoidance Directive; – tax treaties and non-tax treaties with tax consequences both between Member States and between Member States and third countries; – code of conduct for business taxation; – automatic exchange of information; – country-by-country reporting; – arbitration in tax matters; – external strategy for effective taxation regarding non-EU countries; – competition and state aid developments in direct taxation; – the Common Consolidated Tax Base; and – digital significant presence and permanent establishment. As the EU pursues its ambitious tax agenda, taxation's contribution to EU growth and competitiveness and its part in relations with the rest of the world will come into ever clearer focus. In addition to its insights into these trends, the book's unparalleled practical information and analysis will be of great value to tax practitioners dealing with investment analysis, tax planning schemes, and other features of the current international tax landscape.

Preface This book contains the proceedings of the International Tax Conference on the c- th th mon consolidated corporate tax base (CCCTB) that was held in Berlin on 15 – 16 may 2007. The conference was jointly organised by the German Federal Ministry of Finance, the Centre for European Economic Research (ZEW), Mannheim, and the Max Planck Institute (MPI) for Intellectual Property, Competition and Tax Law, Munich. More than 250 participants from all over Europe and other regions, scholars, politicians, business people and tax administrators, discussed the Eu- pean Commission’s proposal to establish a CCCTB. Three panels of tax experts evaluated the common tax base with respect to structural elements, consolidation, allocation, international aspects and administration. The conference made clear that the CCCTB has the potential to overcome some of the most intriguing problems of corporate income taxation within the Common Market. Common tax accounting rules substantially reduce compliance and administrative costs. Consolidation of a group’s profits and losses effects cro- border loss compensation which removes a major tax obstacle for European cro- border investment. At the same time, tax planning with respect to financing and transfer pricing is pushed back within the European Union. Moreover, as far as the CCCTB applies, member states are able to remove tax provisions that are targeted at cross border tax evasion and that might be challenged by the jurisdiction of the Eu- pean Court of Justice.

The Allocation of Multinational Business Income: Reassessing the Formulary Apportionment Option Edited by Richard Krever & François Vaillancourt Although arm’s length methodology continues to prevail in international taxation policy, it has long been replaced by the formulary apportionment method at the subnational level in a few federal countries. Its use is planned for international profit allocation as an element of the European Union’s CCCTB proposals. In this timely book – a global guide to formulary apportionment, both as it exists in practice and how it might function internationally – a knowledgeable group of contributors from Australia, Canada, the United Kingdom and the United States, address this actively debated topic, both in respect of its technical aspects and its promise as a global response to the avoidance, distortions, and unfairness of current allocation systems. Drawing on a wealth of literature considering formulary apportionment in the international sphere and considering decades of experience with the system in the states and provinces of the United States and Canada, the contributors explicate and examine such pertinent issues as the following: the debate about what factors should be used to allocate profits under a formulary apportionment system and experience in jurisdictions using formulary apportionment; application of formulary apportionment in specific sectors such as digital enterprises and the banking industry; the political economy of establishing and maintaining a successful formulary apportionment regime; formulary apportionment proposals for Europe; the role of traditional tax criteria such as economic efficiency, fairness, ease of administration, and robustness to avoidance and incentive compatibility; determining which parts of a multinational group are included in a formulary apportionment unit; and whether innovative profit-split methodologies such as those developed by China are shifting traditional arm’s length methods to a quasi-formulary apportionment system. Providing a comprehensive understanding of all aspects of the formulary apportionment option, this state of the art summary of history, current practice, proposals and prospects in the ongoing debate over arm’s length versus formulary apportionment methodologies will be welcomed by practitioners, policy-makers, and academics concerned with international taxation, all of whom will gain an understanding of the case put forward by proponents for adoption of formulary apportionment in Europe and globally and the counter-arguments they face. Readers will acquire a better understanding of the implications of formulary apportionment and its central role in the current debate about the future of international taxation rules. “...providing (sic) all the intellectual ammunition needed to carefully re-examine one of the ideas traditionally considered as apocryphal by the OECD and to a significant portion of the tax professional community...readers of this book will come away not only with a renewed understanding of the multiple facets of formulary apportionment, but also of some of the fundamental pressure points in the international tax system. Accordingly, it is a welcome and timely addition to the literature. ” Dr. Stjepan Gadžo, Assistant Professor at University of Rijeka, Faculty of Law / British Tax Review 2021, Issue 2, p243-246
