Exploring the Nexus Doctrine In International Tax Law
Description:... 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.
