The phenomenal internationalization of taxation occurring in recent years has called for a second edition of this classic handbook. Even though a quarter of a century has passed, the farsighted first edition has remained in constant use worldwide and has even grown in importance. Now it has been thoroughly updated by the author, who has brought his piercing insight to bear on the current world of international tax law while retaining the book’s practical format, structure of primary materials, and detailed commentary. Emphasizing the need for an international consciousness in relation to issues of taxation, Professor Qureshi focuses extensively on the problems associated with fiscal jurisdiction, international constraints in domestic taxation, double taxation, and tax evasion and avoidance. In particular the following are covered: treaty law with specific reference to taxation; fiscal aspects of international monetary, investment, and trade law; enforcement of international tax claims; exchange of information; assistance in recovery of tax claims; mechanisms for the resolution of international tax disputes; base erosion and profit shifting in the framework of public international law; and contribution of international institutions to fiscal capacity development. Assimilating in one source the basic materials in public international law germane to taxation – including cases, texts of international agreements, discourse in secondary sources, and incisive commentary, all updated to the present – this new edition of the most authoritative and important book in its field will be of immeasurable value to tax practitioners worldwide, national taxation authorities, international institutions, and the international tax community more generally.

This book explains how the tax rules of the various countries in the world interact with one another to form an international tax regime: a set of principles embodied in both domestic legislation and treaties that significantly limits the ability of countries to choose any tax rules they please. The growth of this international tax regime is an important part of the phenomenon of globalization, and the book delves into how tax revenues are divided among different countries. It also explains how U.S. tax rules in particular apply to cross-border transactions and how they embody the norms of the international tax regime.

In an age when cross-border business transactions are increasingly effected without the transference of physical products, revenue concerns of states have led to a multitude of tax disputes based on the concept of ‘nexus’. This important and timely book is the most authoritative to date to discuss one of the major tax topics of our time – the question of how taxing rights on income generated from cross-border activities in the digital age should be allocated among jurisdictions. Demonstrating in prodigious depth that it is the economic nexus of the tax entity or activity with the state, and not the physical nexus, which meets the jurisdictional requirement, the author – a leading authority on this area who is a Senior Commissioner of Income Tax and a Member of the Dispute Resolution Panel of the Government of India – addresses such dimensions of the subject as the following: whether a strict territorial nexus as a normative principle is ingrained in source rule jurisprudence; detailed scrutiny of such classical doctrines as benefit theory, neutrality theory, and internation equity; comparative critique of the Organisation for Economic Co-operation and Development (OECD) and United Nation (UN) model tax treaties; whether international law and customary principles mandate a strict territorial link with the source state for the assumption of tax jurisdiction; whether the economic nexus-based tax jurisdiction and absence of a physical presence breach the constitutional doctrine of extraterritoriality or due process; and whether retrospective tax legislation breaches the principle of constitutional fairness. The book offers a politically informed analysis of the nexus principle and balances the dynamics of physical presence and economic nexus standards, based on an in-depth survey of the historical evolution of judicial pronouncements and international practices in this regard. Dr Singh’s book exposes an urgently needed missing link in the international source rule literature and takes a giant step towards solving the thorny question of appropriate tax apportionment. It sheds brilliant light on the policies states may adopt when signing new tax treaties, so that unintended results may be foreseen and avoided. Tax practitioners, taxation authorities, and academic researchers in the field of international tax law and policy will greatly appreciate the book’s forthright enhancement of the ability to defend challenges based on the nexus doctrine.

In this fresh, objective, and non-argumentative volume in the Elements of International Law series, Peter Hongler combines a comprehensive overview of the technical content of the international tax law regime with an assessment of its crucial relationship to wider international law. Beginning with an assessment of legal principles and foundations, the book considers key general principles, treaty based regimes, and regional integration in tax matters. In the second half of the work Hongler places international tax law in the context of its wider relationships with human rights law, and trade and investment law. He concludes by considering major legal successes and failures and what might be done to address these.

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.

In international tax law, the term ‘beneficial ownership’ refers to which parties involved in a cross-border transaction are entitled to tax treaty benefits. However, determining beneficial ownership is a complex and often disputed issue, subject to different meanings in different countries. Archival research on its early use in tax treaties and in the developing OECD Model reveals that its meaning has changed dramatically over the decades, leading to new interpretations significantly affecting current tax practice and scholarship. This book, dedicated to establishing how beneficial ownership should ideally be interpreted, compares the use and interpretation of benefi-cial ownership, both current and historical, in a wide range of national jurisdictions as well as the EU, ultimately shedding a clearer light than has heretofore been available on the meaning of the term. In her very thorough analysis of the application of beneficial ownership, the author touches on such aspects as the following: – historical development of the beneficial ownership requirement as used in tax treaties and in the OECD Model Tax Convention on Income and on Capital; – rules of double taxation conventions; – application of the OECD’s Action Plan on Base Erosion and Profit-Shifting (BEPS); – the problem of so-called ‘white income’; – use of the substance-over-form principle; – attribution-of-income rules; and – the role of agents, nominees, and conduit companies. Specific analysis of the use and interpretation of beneficial ownership in a domestic law and treaty context in numerous jurisdictions – with particular emphasis on the United Kingdom, Australia, the United States, and Germany – is a major feature of the presentation. As a thorough guide to determining whether a person claiming tax treaty benefits is the true owner – and which parties are excluded from treaty benefits and to what extent – this book will be of immeasurable value to lawyers, tax authorities, policymakers, and other professionals working with taxable international transactions of any kind.
