Controlled foreign company legislation is an international tax topic that has become increasingly important in recent years. Both the OECD and the European Union have taken initiatives to introduce controlled foreign company rules as anti-avoidance tax provisions that are applicable by a large number of states. The OECD released its recommendations on strengthening controlled foreign company rules in the Base Erosion and Profit Shifting Project Action 3 Final Report.

Tax treaty arbitration is a topic that has become more important than ever before. In a post-BEPS world, where tax treaty disputes are expected to increase significantly as a result of the different measures taken to address treaty abuse, a well-functioning dispute resolution mechanism is key to solving tax treaty disputes. Both the OECD and the European Union took initiatives to improve the mechanisms for dispute resolution in tax matters. The OECD amended article 25 of the OECD Model on the mutual agreement procedure and the European Union adopted Council Directive 2017/1852 on tax dispute resolution mechanisms in the European Union. The aim of this book is to provide tax authorities, policymakers, courts and practitioners an overview of the effectiveness of tax treaty arbitration and the approach towards the recent changes in 36 countries. This book comprises 36 national reports from countries across the globe and is the outcome of a conference on tax treaty arbitration that took place from 5 to 7 July 2018 in Rust (Austria).

The entitlement to tax treaty benefits is of pivotal importance for taxpayers in order to obtain treaty benefits. However, the application and interpretation of the respective tax treaty provisions are not always straightforward and may often raise various questions. This is all the more true now that the OECD has introduced a number of new provisions regarding the entitlement to tax treaties into its Model Convention as part of the BEPS Project. This book analyses several crucial areas concerning the entitlement to tax treaties. The topics covered include: - The application of the principal purpose test, limitation on benefits clauses and the beneficial ownership test - The relevance of the term “person” within the OECD Model - Dual residence for individuals and non-individuals - The tax treaty entitlement of hybrid entities - The entitlement to protection against discriminatory taxation - The personal scope of the mutual agreement procedure and arbitration provisions, and the mutual assistance provisions This book is part of the WU Institute for Austrian and International Tax Law – Tax Law and Policy Series.

The increasingly digitalized global economy is undermining the usefulness of many traditional tax concepts. In addition to issues of double taxation and double non-taxation, important questions arise concerning the allocation of taxing rights in respect of income from cross-border digital transactions. This is the first book to analyse what changes are possible, necessary and feasible in order to forestall the unravelling of the existing international tax framework. Focusing in turn on the legal framework, specific proposals for adapting tax concepts for the digital economy, types of transactions and administrative issues such as those around data protection and digital currencies, the expert contributors discuss such challenges to taxation as the following: the pervasiveness of intangible assets; new value creation models; the ascendance of the sharing economy and digital services; virtual currencies; the importance of user participation for digital platforms; cloud computing; the impact of Big Data on tax enforcement; virtual business presence; and the influence of robotization. Throughout, the authors describe and analyse proposals made by the Organisation for Economic Co-operation and Development (OECD), the European Union (EU) and individual countries and their likely impact going forward. They also attend to the limits imposed on reform possibilities by public international law, EU law and constitutional law. It is generally acknowledged that there is a need to monitor how the digital transformation may be impacting value creation. This book is a key milestone toward developing a durable, long-term solution to the tax challenges posed by the digitalization of the economy. With its thorough scrutiny of proposals for digital services tax and virtual permanent establishments, insightful analysis of digital services and detailed description of the impact of big data on tax administration and taxpayer protection, it will quickly prove indispensable for tax practitioners and the international tax community more generally.

Time is a crucial dimension in the application of any law. In tax law, however, where an environment characterized by rapid change on the national, European, and international levels complicates the provision of accurate legal advice, timing is particularly sensitive. This book is the first to analyse the relationship between time and three key areas of tax: treaties, EU law, and constitutional law issues, such as legal certainty and individual rights. Among the numerous timing issues arising out of applying tax rules, the book addresses the following: – time limits within which relief must be requested; – statutes of limitation for claiming a tax refund; – transitional issues relating to changes in tax treaties; – attribution of profits and expenses to a moving or closed-down business; – effect of tax-related CJEU decisions and EU directives; – compliance of exit tax regimes with free movement; – limits of retroactivity under principles protected by the EU Charter and the ECHR; and – conflict between efficiency of taxation and individual rights. Derived from a recent conference organized by the prestigious ATOZ Chair for European and International Taxation at the University of Luxembourg, the book brings together contributions from leading tax experts from various areas of tax practice, academia, and the judiciary. Among other issues, the book notably expands on how economic theory can inform a constitutional analysis of the timing of taxation. There is no other work that concentrates so usefully on the difficulties associated with applying tax rules – whether arising from treaties, jurisprudence, or policy – to changing circumstances over time. This book will quickly prove itself to be an indispensable resource for European tax lawyers, policymakers, company counsels, and academics.
