In the wake of the Panama Papers scandal and similar leaks, tax havens are now firmly in the spotlight. Today, roughly half of all global trade still passes through tax haven jurisdictions, costing millions in lost revenue to countries around the world. Such practices affect all of us, but are most keenly felt by poorer people in developing countries, where unfair tax practices have become a major obstacle to development, and which have allowed multinational corporations to continue to exploit developing economies. This collection argues that, for developing countries to achieve social justice and lasting prosperity, they must take control of their own tax destinies, and that this will also be crucial to achieving the Sustainable Development Goals. Covering such topics as natural resource management, representation in global tax institutions and effective strategies for building and protecting tax bases, the collection brings together expertise from a variety of countries and disciplines. It explores the options available to developing countries, and provides a basis for concerted action by tax authorities, policy makers, academics and civil society experts to design tax systems that can sustain a just society.
