Book excerpt: Major changes in EU tax law demand an analysis of not just the current state of the field, but also forthcoming EU-level policy initiatives and their likely implications for taxpayers, regulators, and national legislatures alike. This book, the first in-depth commentary and analysis of such developments, offers exactly that. Twenty EU tax and policy experts examine the impact of EU Treaty provisions and recent ECJ case law on EU tax law, and provide well-informed assessments of current and anticipated EU tax policy initiatives and their potential impacts. Taxpayers, their advisors, national tax administrations, and national legislators will find relevant chapters to aid their understanding of, and to allow them to proactively address, EU tax law issues, such as: – non-discrimination; – state aid rules; – fundamental freedoms; – discretionary power of national tax authorities; – tax competition in the internal market; – cross-border exchange of tax information; – corporate tax harmonization; – EU and Member States’ external relations; and – the limits of judicial authority in tax policy. As an authoritative,detailed guide to recent and future developments in EU tax law, with highly informed insights into their practical effect, this book will be a welcome addition to the arsenal available to tax practitioners dealing with European tax matters, as well as interested policymakers and academics.
