The current framework of international corporate taxation—based on the “arm’s-length principle” to split profits of multinationals between countries—is increasingly being challenged by experts, businesses and civil society. New international standards and guidelines under the G20/OECD BEPS initiative aim at addressing key weaknesses in the current framework, but do not tackle the root cause of the significant spillovers inherent to the system. At the same time, digitalization and the growing importance of intangible assets create new challenges. These developments have elevated fundamental discussions on whether the arms-length principle is sustainable. While much has been written about the problems with the current system, much less is known about the advantages and disadvantages of an alternative system, based on a formulary approach to profit attribution. This conference will bring together various experts to discuss these issues.

Participation in the conference is by invitation only.

Session 1: Review of issues

  • How do formulary methods work, and what are their advantages and possible problems?
  • How do factors in the formula relate to international tax principles, such as source and destination? How should intangible assets or digital services be incorporated?
  • What is required to implement formulary apportionment on a global scale? Is international coordination required?

  • What are the implications of these choices for the behavior of firms?
  • How does the system affect tax competition between subnational governments?

  • Which formula/principle is more robust? Should countries be able to choose their own formula? What will be the welfare implications?
  • Can formulary methods be used as a complement to the current system, such as under profit split methods and as a base for minimum taxation?
