Recent deficit reduction and tax reform plans have included broad proposals to reform the U.S. international corporate tax system. These proposals have raised concerns over how changing the way American multi-national corporations are taxed could impact the deficit and debt, domestic job markets, competitiveness, and the use of corporate tax havens, among other things. An informed debate about how to reform the system governing the taxation of U.S. multi-national corporations requires careful consideration of these issues, as well as a basic understanding of several features of the current system. This book provides a general introduction to the basic concepts and issues relevant to the U.S. international corporate tax system and with a focus on how other countries have used tax reform to help their companies compete in the global market and create jobs.
