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.

Modern-day tax treaties have their foundations in one of the three Model Tax Treaties developed by the League of Nations in 1928. Using previously unexplored archival material, Sunita Jogarajan provides the first in-depth examination of the development of the League's Models. This new research provides insights into questions such as the importance of double taxation versus tax evasion; the preference for source-taxation versus residence-taxation; the influence of theory and practice on the League's work; the development of bilateral rather than multilateral treaties; the influence of developing countries on the League's work; the role of Commentary in interpreting model tax treaties; and the influential factors and key individuals involved. A better understanding of the development of the original models will inform and help guide interpretation and reform of modern-day tax treaties. Additionally, this book will be of interest to scholars of international relations and the development of law at international organisations.

Although the future extent and effects of global climate change remain uncertain, the expected damages are not zero, and risks of serious environmental and macroeconomic consequences rise with increasing atmospheric greenhouse gas concentrations. Despite the uncertainties, reducing emissions now makes sense, and a carbon tax is the simplest, most effective, and least costly way to do this. At the same time, a carbon tax would provide substantial new revenues which may be badly needed, given historically high debt-to-GDP levels, pressures on social security and medical budgets, and calls to reform taxes on personal and corporate income. This book is about the practicalities of introducing a carbon tax, set against the broader fiscal context. It consists of thirteen chapters, written by leading experts, covering the full range of issues policymakers would need to understand, such as the revenue potential of a carbon tax, how the tax can be administered, the advantages of carbon taxes over other mitigation instruments and the environmental and macroeconomic impacts of the tax. A carbon tax can work in the United States. This volume shows how, by laying out sound design principles, opportunities for broader policy reforms, and feasible solutions to specific implementation challenges.

Or her tax trial

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.
