The OECD's Global Minimum Tax and Its Implementation in the EU
The OECD’s Global Minimum Tax and its Implementation in the EU – A Legal Analysis of Pillar Two in the Light of Tax Treaty and EU Law
Author: Valentin Bendlinger
Publisher: Kluwer Law International B.V.
ISBN: 9403532971
Category : Law
Languages : en
Pages : 449
Book Description
Rarely in the history of international tax law have there been so many evolutions in such a short space of time: In a dizzying array of reports, work programmes, consultations and announcements, the OECD, with the active support of the EU, has created a framework for a global minimum tax (Pillar Two or GloBE). In the meanwhile, jurisdictions are faced with the practical difficulties of incorporating an incredibly complex set of rules into their domestic legal systems. This book aims to shed light on the fundamental and technical issues surrounding the global minimum tax. It seeks to unravel the complex ramifications of GloBE’s technical framework and aims to explore the relationship between the OECD’s soft law materials, including the OECD’s GloBE Model Rules and the GloBE Commentary, tax treaties and the EU’s recently adopted GloBE-Directive. The author not only analyses Pillar Two from a technical and a policy perspective but also provides for a comprehensive examination of the compatibility of Pillar Two with tax treaties and EU law. To this end, the analysis also includes practical examples and illustrates solutions to numerous technical and policy issues of Pillar Two. Among the seminal matters covered are the following: History and Background of the global minimum tax discussion. Detailed technical considerations on the design of Pillar Two, including its scope, the determination of both the ‘GloBE Income’ as well as the ‘Adjusted Covered Taxes’ and the computation of the effective tax rate as well as the computation and collection of the final ‘Top-up Tax’ liability, including the application of the QDMTT, IIR, and UTPR. Tax policy implications and deficiencies of the final design of Pillar Two. The relation of Pillar Two to the current distribution of taxing rights under bilateral tax treaties. The analysis includes the compatibility of the QDMTT, IIR, and UTPR with existing tax treaties and the resolution of potential normative conflicts, both between tax treaties and domestic implementations of Pillar Two as well as between tax treaties concluded by EU Member States and the EU’s GloBE-Directive. The role of the GloBE-Directive within the EU’s legal order, including the issue of EU internal and external competence as well as the substantive compatibility of Pillar Two with primary law, such as the fundamental freedoms. Detailed comparisons between the OECD’s GloBE Model Rules and the EU’s GloBE-Directive elucidate common points and deviations. In addition to comprehensive technical considerations, the book also provides a comprehensive tax policy perspective on the global minimum tax. For its unparalleled clarification of the issues alone, this book will prove invaluable to practitioners, tax authorities, policymakers, and academics concerned with the implementation and application of Pillar Two. ‘Valentin Bendlinger’s book is an outstandingly remarkable work on a highly complex topic. The structure, clarity of thinking, and legal argumentation are excellent, and the legal and policy results throughout are profoundly argued. The book successfully ties together broad concepts of international and European (tax) law with highly complex and novel issues of the taxation of multinational enterprises. It should be highlighted that Valentin Bendlinger succeeded in leading the reader from the history and policy through a “jungle” of unprecedented rules to overarching fundamental issues of how the new taxation framework is to be placed in the international and European legal order.’ – Prof. DDr Georg Kofler, LLM (NYU), Vienna University of Economics and Business.

Annotations on the OECD Global Anti-Base Erosion Model Rules (Pillar 2)
Author: Dennis Weber
Publisher: Kluwer Law International B.V.
ISBN: 9403544066
Category : Law
Languages : en
Pages : 614
Book Description
Although still under development, Pillar 2 of the OECD Global Anti-Base Erosion Model Rules is already posing significant challenges for taxation authorities worldwide. Intended to establish a floor in the possibilities for countries to compete for corporate investment with each other in the field of corporate income taxation, the Pillar 2 Rules arising from the OECD/G20 Inclusive Framework have been agreed on by 140 countries. This book provides the first in-depth survey of the implications of the Rules for all stakeholders, with detailed annotations by nineteen renowned experts in the field of multinational corporate taxation who describe the relevant provisions with examples and considerations addressing their scope, functioning, and interaction. Undergirded by a comprehensive discussion of the Rules, their technical operation, and the administrative guidance provided by OECD, topics covered include the following: definitions of tax terms for Pillar 2 purposes; computation of income or loss, adjusted covered taxes, effective tax rate, and top-up tax; jurisdictional blending and loss offsets; effect of corporate restructurings and holding structures; excluded categories of income; carve-out opportunities under the Substance-Based Income Exclusion (SBIE); transitional country-by-country and time-limited safe harbours; and differences and interactions between the OECD Global Anti-Base Erosion (GloBE) and both the EU Pillar 2 Directive and the US Global Intangible Low-Taxed Income (GILTI) regimes. It has been estimated that the GloBE reform would produce a worldwide additional tax revenue of USD 200 billion annually. It has thus become imperative for taxation authorities, tax practitioners, and multinational corporate counsel to become as aware as possible of the intricacies of the Pillar 2 Rules, and for this reason, this detailed discussion and analysis will be greatly appreciated by taxation professionals worldwide.

Article 12B UN Model Convention 2021
Author: Christian Knotzer
Publisher: Kluwer Law International B.V.
ISBN: 940352488X
Category : Law
Languages : en
Pages : 551
Book Description
This groundbreaking book – a major contribution addressing the imperative to find a solution to what has been labelled as the Tax Challenges Arising from the Digitalization of the Economy – provides the first comprehensive analysis of Article 12B of the UN Model Double Taxation Convention 2021, a model distributive rule for ‘Income from Automated Digital Services’. In extensive detail, the author thoroughly examines the article’s underlying principles, its individual provisions, the tax policy context that surrounds it, how it might be applied, and what its strengths and weaknesses are. The author’s analysis (which includes a paragraph-by-paragraph discussion of the article and examines its Commentary in extensive detail) covers all aspects of the article and its significance, including the following: how to reconcile the approach taken by Article 12B UN Model Convention with general principles underlying the coordination of taxing claims; legal and tax policy relation to other provisions of the UN Model Convention and to the OECD/Inclusive Framework Pillar One/Amount A; influence of developing countries in forums of international tax coordination; the value of country positions and minority views in Model Conventions; categories of digital services; the novel option for annual net taxation in Article 12B(3) UN Model Convention; and the proposal for a UN fast-track instrument. It is not surprising that the ubiquitous digitalization of the economy has led to a widespread sense of unease in the international tax community. Practitioners and policymakers who face this issue in their day-to-day work will greatly appreciate this book’s clear explanation of how Article 12B UN Model Convention works and benefit from its consideration of how it is likely to be implemented in the international double taxation treaty network.
