The book is written for students of business economics and tax law. It focuses on investment and financing decisions in cross-border situations. In particular, the book deals with: Legal structures of international company taxation, International double taxation, Source-based and residence-based income taxation, International investment and profit shifting, International corporate tax planning, International tax planning and European law, Harmonization of corporate taxation in the European Union, International tax planning and tax accounting. International tax law is designed to avoid international double taxation and to combat international tax avoidance. Nevertheless, companies investing in foreign countries may suffer from international double taxation of profits. On the other hand, these companies may also be able to exploit an international tax rate differential by means of cross-border tax planning.
