This article is a summary of the findings of the book "Proportionality and Fair Taxation" published in 2014, in which the author investigated the role of the proportionality principle coupled with the standard of reasonableness in assessing specific tax issues and the overall fairness of particular taxes and tax systems. Among those issues, the author points out equality and non-discrimination, retrospective taxation, tax penalties and sanctions, specific and general anti-avoidance rules, as well as the application of proportionality in tandem with reasonableness in double taxation conventions, human rights and tax related rules of international trade.

This in-depth coverage recognizes that tax law does not exist in isolation and reveals how tax law frequently overlaps with competition law, administrative law, environmental law, and constitutional law, and how principles from these areas of practice can affect the adjudication of tax cases. Proportionality and Fair Taxation is an important guide for all involved in tax law. Tax lawyers will find valuable insights that will help with both litigation and counselling whilst practitioners, academics, and policymakers will appreciate how the book reveals the extent to which an informed awareness of proportionality coupled with reasonableness is essential for the fair, consistent, and effective application of tax rules or measures.

This new and updated edition of The Flat Tax—called "the bible of the flat tax movement" by Forbes—explains what's wrong with our present tax system and offers a practical alternative. Hall and Rabushka set forth what many believe is the most fair, efficient, simple, and workable tax reform plan on the table: tax all income, once only, at a uniform rate of 19 percent.

Most people would agree that tax systems ought to be 'just', and perhaps a great deal more just than they are at present. What is more difficult is to agree on what tax justice is. This book considers a range of different approaches to, and ideas about the nature of tax justice and covers areas such as: - imbalances in international tax arrangements that deprive developing countries of revenues from natural resources and allow wealthy taxpayers to use tax havens; - protests against governments and large business; - attempts to influence policy through more technical means such as the OECD's Base Erosion and Profits Shifting project; - interpersonal matters, such as the ways in which tax systems disadvantage women and minorities; - the application of wider philosophical or economic theories to tax systems. The purpose of the book is not to iron out these underlying differences into a grand theory, but rather to gain a more precise understanding of how and why we disagree about tax justice. In doing so the editors are assisted by a stellar cast of contributors from four continents, with a wide variety of views and experiences but a common interest in this central question of how to agree and disagree about tax justice. This is, of course, not only an intellectual exercise but also a necessary precursor to achieving real-world change.

Resumen del editor: "The increasing globalization and the restructuring of the European legal framework by the Treaty of Lisbon are important factors to suggest that the traditional separation of spheres between taxation and human rights should be revisited. This book examines the issues surrounding the impact of the Lisbon Treaty on the guarantee and enforcement of human rights in the area of EU (tax) law and explores the possible development and potential impact of human rights in the field of taxation in this age of global law."
