This book lays out what we know about the scale, history and impacts of tax abuse. From profit-shifting by multinational corporations to the exploitation of offshore tax havens. It sheds light on the people and organisations that enable tax abuse, and the stark social inequalities it creates.

Crucially, it also explores what we can do about it. What are the practical realities of challenging the threats of tax injustice and of holding abusers accountable? What are the policies and institutional shifts we need to see and fight for?

It is estimated that cross-border tax abuse accounts for around half a trillion dollars of lost revenue around the world each year. This is important. Alex Cobham shows us that tax is more than just business regulation or economic policy. It is a powerful tool for creating a fair and just society. It is our social superpower.

Alex Cobham is an economist and chief executive of Tax Justice Network.

Written by leading social scientists, the What Do We Know and What Should We Do About...? series offers concise, up-to-date overviews of issues often oversimplified, misrepresented or misunderstood and shows you how to enact change.
