Tax Sovereignty in the BEPS Era

Book excerpt: The power of a country to freely design its tax system is generally understood to be an integral feature of sovereignty. However, as an inevitable result of globalization and income mobility, one country’s exercise of tax sovereignty often overlaps, interferes with, or even impedes that of another. In this collection of essays, internationally respected practitioners and academics reveal how the OECD’s Base Erosion and Pro t Shifting (BEPS) initiative, although a major step in the right direction, is insuf cient to resolve the tax sovereignty paradox. Each contribution deals with different facets of a single topic: How tax sovereignty is shaped in a post ,BEPS world. The contributors provide in ,depth analysis of such relevant issues as the following: hy multilateral cooperation and soft law consensus are the preferred solutions to a loss of autonomy over national tax policy; – how digital commerce has upended traditional notions of source and residence; – why residence and source continue to be the two essential building blocks of tax sovereignty and the backbone of the international tax system; – how developing countries can take advantage of the new international tax architecture to ensure that their voices are truly shaping the standards; and – transfer pricing reform. Collectively, the authors provide an authoritative commentary on the necessary preconditions for exercising the power to tax in today’s world. Their perspectives and recommendations will prove of great value to all policymakers, legislators, practitioners, and academics in the international taxation arena.
