This book brings together studies of leading tax economists and lawyers to assess the various reform proposals and examine the effects of tax reform in several distinct areas. Together, these studies and comments on them present a balanced evaluation of professional opinion on the issues that will be critical in the tax reform debate.

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.

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

Our tax system is a mess. And the reason for that mess is, our tax system is incoherent. A well-designed tax system is like a good jigsaw puzzle: all the pieces fit together snugly, so when the whole thing is fully assembled, it forms a coherent picture. But our current tax system is disjointed, with parts that don't logically fit together. That results in inconsistencies, complexity, loopholes, and distorted incentives. We need a tax system that make sense. As this book shows however, making a traditional income tax coherent is an impossible goal. But coherence is achievable if we adjust our target, and complete the switch to a consumed-income tax -- a system that taxes all income, not when it is earned, but when that income is consumed. The move towards a consumed-income tax was begun decades ago, when we first adopted IRAs and other tax-deferred savings accounts. We just needed to complete the evolution. The book explores a variety of tax issues -- among them savings, small businesses, owner-occupied houses, and corporations -- and develops seven groups of recommended changes. These changes would result in a tax system that would be pro-growth, by eliminating the existing disincentives to saving and investment. But the tax system would also remain progressive, with the wealthy taxed as much as and perhaps even more than currently. That combination could make the recommended changes attractive to members of both parties, and might bring to a close the political seesaw in tax policy that we've experienced over that last several decades.

This study explores how the tax design called the X tax could alleviate the complexities and avoidance opportunities plaguing the existing U.S. system for taxing international business income.
