This is the fifth edition of Tax Policy Reforms: OECD and Selected Partner Economies, an annual publication that provides comparative information on tax reforms across countries and tracks tax policy developments over time. The report covers the latest tax policy reforms in all OECD countries, as well as in Argentina, China, Indonesia and South Africa.

This report investigates how tax structures can best be designed to support GDP per capita growth.

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.

Going for Growth 2021 identifies country-specific structural policy priorities for the recovery across OECD and key non-member countries (Argentina, Brazil, The People’s Republic of China, Costa Rica, India, Indonesia and South Africa). It frames the main policy challenges of the current juncture along three main areas: building resilience; facilitating reallocation and boosting productivity growth for all; and supporting people in transition.

This first edition of Tax Policy Reforms in the OECD focuses on the tax reforms that were introduced in 2015 and identifies the most significant tax policy reforms as well as common tax policy trends across groups of countries.

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.
