Special Economic Zones Facing the Challenges of International Taxation: BEPS Action 5, EU Code of Conduct, and the Future

Corporate taxation and particularly corporate tax incentives that jurisdictions introduce in special economic zones have not, until recently, been subject to extensive international regulation. Only in the last decade has a regime of soft law standards and European Union measures with extraterritorial effect been constructed. This article explains how the Base Erosion and Profit Shifting Action Plan developed by the Organisation for Economic Co-operation and Development (OECD) and the European Union Code of Conduct for Business Taxation interact with corporate tax incentives in special economic zones. Empirical evidence from Latin American and Caribbean jurisdictions shows that this emerging international regime began having an impact on special economic zone laws beyond the OECD and European Union Member States. An analysis of ongoing negotiations on the further developments of the international tax regime permits the cautious conclusion that the regulation of SEZs may in the future be affected in a more fundamental manner by international norms. Thereby, the article shows that special economic zones’ unilateralism in corporate taxation may be slowly receding in contrast to other areas of international economic governance.
