This paper explores the nature, significance and policy implications of spillovers in international corporate taxation—the effects of one country’s rules and practices on others. It complements current initiatives focused on tax avoidance by multinationals, notably the G20-OECD project on Base Erosion and Profit shifting (BEPS). The paper draws on the IMF’s experience on international tax issues with its wide membership, including through technical assistance (TA), and on its previous analytical work, to analyze spillovers and how they might be addressed. In doing so, it goes beyond current initiatives to look at a wide set of possible responses.

This paper articulates and, using newly-assembled data, explores how international taxation affects aggregate tangible cross-border investment. Spillovers from statutory tax rates abroad seem: As sizable as effects from the host’s rate; larger than previous consensus values (attributed to a systematic bias from FDI data); and consistent with ‘implicit’ profit shifting through real investment (rather than ‘paper’ profit shifting). Contrary to much policy discussion, the results also imply that: Host countries’ marginal effective tax rates have at best a weak effect on real investment; those elsewhere have none; and, applied to the prospective global minimum tax, inward tangible investment in most sample countries will increase.

This paper explores how corporate taxes affect the financial structure of multinational banks. Guided by a simple theory of optimal capital structure it tests (i) whether corporate taxes induce subsidiary banks to raise their debt-asset ratio in light of the traditional debt bias; and (ii) whether international corporate tax differentials vis-a-vis foreign subsidiary banks affect the intra-bank capital structure through international debt shifting. Using a novel subsidiary-level dataset for 558 commercial bank subsidiaries of the 86 largest multinational banks in the world, we find that taxes matter significantly, through both the traditional debt bias channel and the international debt shifting that is due to the international tax differentials. The latter channel is more robust and tends to be quantitatively more important. Our results imply that taxation causes significant international debt spillovers through multinational banks, which has potentially important implications for tax policy.

Because the actions of multinational corporations have a clear and direct effect on the flow of capital throughout the world, how and why these firms behave the way they do is a major issue for national governments and their policymakers. With an unprecedented ability to adjust the scale, character, and location of their global operations, international corporations have become increasingly sensitive to the kind and degree of tax obligations imposed on them by both host and home countries. Tax rules affect the volume of foreign direct investment, corporate borrowing, transfer pricing, dividend and royalty payments, and research and development. National governments that tax the profits of international firms face important challenges in designing tax policies to attract them. This collection examines the global ramifications of tax policies, offering up-to-date, theoretically innovative, and empirically sound perspectives on a problem of immense significance to future economic growth around the globe.

The increasing globalization of economic activity is bringing an awareness of the international consequences of tax policy. The move toward the common European market in 1992 raises the important question of how inefficiencies in the various tax systems—such as self-defeating tax competition among member nations—will be addressed. As barriers to trade and investment tumble, cross-national differences in tax structures may loom larger and create incentives for relocations of capital and labor; and efficient and equitable income tax systems are becoming more difficult to administer and enforce, particularly because of the growing importance of multinational enterprises. What will be the role of tax policy in this more integrated world economy? Assaf Razin and Joel Slemrod gathered experts from two traditionally distinct specialties, taxation and international economics, to lay the groundwork for understanding these issues, which will require the attention of scholars and policymakers for years to come. Contributors describe the basic provisions of the U.S. tax code with respect to international transactions, highlighting the changes contained in the U.S. Tax Reform Act of 1986; explore the ways that tax systems influence the decisions of multinationals; examine the effect of taxation on trade patterns and capital flows; and discuss the implications of the opening world economy for the design of optimal international tax policy. The papers will prove valuable not only to scholars and students, but to government economists and international tax lawyers as well.

This open access volume addresses the link between international taxation, the 2030 Sustainable Development Agenda and the medium-term revenue strategy concept. It also analyses how countries and governments can reinforce this link in current and future initiatives in international taxation, including the base erosion profit shifting project initiated by the Organization for Economic Co-operation and Development with the political mandate of the G20. It discusses the 2030 Sustainable Development Agenda that are relevant for taxation and assesses the current work done by international organizations, regional tax organizations and countries to achieve these Sustainable Development Goals. The contributions to this volume provide an interdisciplinary mix of expertise in tax law, international political economy, global governance and international relations. Through these different perspectives, this volume provides an elaborate reference and evaluation framework for multilateral cooperation on tax and development to strengthen the revenue system of developed and developing countries. This topical volume is of interest to students and researchers of the social sciences, law and economics, as well as policy makers working on taxation.

In this book the authors provide a new treatment of international taxation, one that focuses on the interactions between fiscal policies of sovereign nations and the magnitude and directions of international capital and goods flow in an integrated world economy.

In the discussion of the Board work program on June 3, 2013, it was urged that the Fund be more present in current discussions of international tax issues. This note reviews key issues and initiatives in this area, and sets out a work plan that is focused on the Fund‘s mandate and macroeconomic expertise and that complements the work of other institutions, notably the OECD.
