International Corporate Taxation

The book describes the difficulties of the current international corporate income tax system. It starts by describing its origins and how changes, such as the development of multinational enterprises and digitalization have created fundamental problems, not foreseen at its inception. These include tax competition—as governments try to attract tax bases through low tax rates or incentives, and profit shifting, as companies avoid tax by reporting profits in jurisdictions with lower tax rates. The book then discusses solutions, including both evolutionary changes to the current system and fundamental reform options. It covers both reform efforts already under way, for example under the Inclusive Framework at the OECD, and potential radical reform ideas developed by academics.

The book is written for students of business economics and tax law. It focuses on investment and financing decisions in cross-border situations. In particular, the book deals with: Legal structures of international company taxation, International double taxation, Source-based and residence-based income taxation, International investment and profit shifting, International corporate tax planning, International tax planning and European law, Harmonization of corporate taxation in the European Union, International tax planning and tax accounting. International tax law is designed to avoid international double taxation and to combat international tax avoidance. Nevertheless, companies investing in foreign countries may suffer from international double taxation of profits. On the other hand, these companies may also be able to exploit an international tax rate differential by means of cross-border tax planning.

The policy paper Corporate Taxation in the Global Economy stresses the need to maintain and build on the progress in international cooperation on tax matters that has been achieved in recent years, and in some respects now appears under stress. With special attention to the circumstances of developing countries, the paper identifies and discusses various options currently under discussion for the international tax system to ensure that countries, and in particular low-income countries, can continue to collect corporate tax revenues from multinational activities.

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.

The tax rules of the United States and other countries have intended and unintended effects on the operations of multinational corporations, influencing everything from the formation and allocation of capital to competitive strategies. The growing importance of international business has led economists to reconsider whether current systems of taxing international income are viable in a world of significant capital market integration and global commercial competition. In an attempt to quantify the effect of tax policy on international investment choices, this volume presents in-depth analyses of the interaction of international tax rules and the investment decisions of multinational enterprises. Ten papers assess the role played by multinational firms and their investment in the U.S. economy and the design of international tax rules for multinational investment; analyze channels through which international tax rules affect the costs of international business activities; and examine ways in which international tax rules affect financing decisions of multinational firms. As a group, the papers demonstrate that international tax rules have significant effects on firms' investment and other financing decisions.

Analysis of the case law test for corporate residence, developed mainly in the United Kingdom beginning in the 19th century, the residence definition adopted in the OECD Model Convention and some of its more common variants, and Canadian domestic statutory provisions.

This paper reviews the rapidly growing empirical literature on international tax avoidance by multinational corporations. It surveys evidence on main channels of corporate tax avoidance including transfer mispricing, international debt shifting, treaty shopping, tax deferral and corporate inversions. Moreover, it performs a meta analysis of the extensive literature that estimates the overall size of profit shifting. We find that the literature suggests that, on average, a 1 percentage-point lower corporate tax rate will expand before-tax income by 1 percent—an effect that is larger than reported as the consensus estimate in previous surveys and tends to be increasing over time. The literature on tax avoidance still has several unresolved puzzles and blind spots that require further research.

Recent deficit reduction and tax reform plans have included broad proposals to reform the U.S. international corporate tax system. These proposals have raised concerns over how changing the way American multi-national corporations are taxed could impact the deficit and debt, domestic job markets, competitiveness, and the use of corporate tax havens, among other things. An informed debate about how to reform the system governing the taxation of U.S. multi-national corporations requires careful consideration of these issues, as well as a basic understanding of several features of the current system. This book provides a general introduction to the basic concepts and issues relevant to the U.S. international corporate tax system and with a focus on how other countries have used tax reform to help their companies compete in the global market and create jobs.
