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 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.

There is no consensus on how strongly the Tax Cuts and Jobs Act (TCJA) has stimulated U.S. private fixed investment. Some argue that the business tax provisions spurred investment by cutting the cost of capital. Others see the TCJA primarily as a windfall for shareholders. We find that U.S. business investment since 2017 has grown strongly compared to pre-TCJA forecasts and that the overriding factor driving it has been the strength of expected aggregate demand. Investment has, so far, fallen short of predictions based on the postwar relation with tax cuts. Model simulations and firm-level data suggest that much of this weaker response reflects a lower sensitivity of investment to tax policy changes in the current environment of greater corporate market power. Economic policy uncertainty in 2018 played a relatively small role in dampening investment growth.

This report is the ninth edition of the OECD's Tax Administration Series. It provides internationally comparative data on aspects of tax systems and their administration in 59 advanced and emerging economies.

The book provides a clear introduction to international taxation and presents its material in a global context, explaining policy, legal issues and planning points central to taxation issues, primarily from the viewpoint of a multinational group of companies. It uses examples and diagrams throughout to aid the reader's understanding and offers more in-depth material on many important areas of the subject. Traditionally published every 2 years in both print and digital formats, this content is a core requirement for student reading lists at both undergraduate and post graduate level. Fully updated to cover all new tax legislation and developments in light of the OECD BEPS project implementation, key areas to be included in this new edition are: - changes proposed by BEPS 2.0 in relation to taxation and the digital economy, including Pillar Two and the proposed new UN Model Article 12B; - further progress on the implantation of OECD Base Erosion and Profit Shifting implementation, including: -- an update on the implementation of BEPS recommendations including artificial avoidance of permanent establishment status and prevention of treaty abuse; -- the implementation of transfer pricing documentation and country-by-country reporting; -- multilateral instrument implementation; - the impact of Covid-19 on international taxation; - further developments in European direct taxation including the transparency package, directives on anti-tax avoidance and the common corporate tax base and state aid cases (Apple in particular) and updates to the Directive on Administrative Cooperation, and the new communication on Business Taxation for the 21st Century. - Proposals in relation to the taxation of digital business, in particular the OECD's unified approach and the UN modifications to the Model Double Taxation Convention. - Proposals for a global minimum corporate tax rate to curb base erosion and tax competition.

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.

The international tax system is in dire need of reform. It allows multinational companies to shift profits to low tax jurisdictions and thus reduce their global effective tax rates. A major international project, launched in 2013, aimed to fix the system, but failed to seriously analyse the fundamental aims and rationales for the taxation of multinationals' profit, and in particular where profit should be taxed. As this project nears its completion, it is becomingincreasingly clear that the fundamental structural weaknesses in the system will remain. This book, produced by a group of economists and lawyers, adopts a different approach and starts from first principles in order to generate an international tax system fit for the 21st century. This approach examines fundamental issues of principle and practice in the taxation of business profit and the allocation of taxing rights over such profit amongst countries, paying attention to the interests and circumstances of advanced and developing countries. Once this conceptual framework is developed, the book evaluates the existing system and potential reform options against it. A number of reform options are considered, ranging from those requiring marginal change to radically different systems. Some options have been discussed widely. Others, particularly Residual Profit Split systems and a Destination Based Cash-Flow Tax, are more innovative and have been developed at some length and in depth for the first time in this book. Their common feature is that they assign taxing rights partly/fully to the location of relatively immobile factors: shareholders or consumers.
