International Tax Law For Multinational Enterprises


Admission requirements

STUDENTEN FISCAAL RECHT KUNNEN NIET DEELNEMEN (i.v.m. overlap met verplichte vakken internationaal belastingrecht).

Successful completion of at least one year of university education in law. Proficiency in English both orally and in writing. The overall maximum number of students in the course is 25. We will be admitting max. 15 exchange students to the course as well as max. 10 law students (non-tax).


In today’s world many companies operate across borders. We call them multinational enterprises. In a simple form a company resident in Germany has a sales office in Belgium. In a more complex case a company may have its headquarters in Japan, the production facilities in China, while the research and development is done in the Netherlands, the brand name is kept in a company on the Cayman Islands and the sales are done in many countries across the world.

Multinational enterprises encounter taxation in all the countries they are active in. This course explores the double taxation, low taxation and the double non-taxation that may arise in those cases. We will study why and how countries tax multinational enterprises and how tax treaties for the avoidance of double taxation function. We will also pay attention to the ways multinationals may use the rules to minimize taxation and to the disapproval in society about the level of taxes paid by multinationals. We will discuss the role and dilemma of governments in tax avoidance: they want to attract businesses and also improve the rules. We will also discuss the role of multinationals themselves: they want to maximize profits, but may want to behave more socially responsible and pay ‘a fair share’ of tax. We will look into the solutions proposed by the OECD, G20, the EU, countries and civil society to tackle tax avoidance by multinationals.

Course objectives

Objectives of the course
The principal objectives of this course are to introduce students to why and how countries typically tax multinational enterprises, the phenomenon of tax avoidance, the dilemmas faced by both countries and multinationals in their attitudes towards tax avoidance, and the current proposals to tackle tax avoidance presented by international organizations, EU, countries and civil society

Achievement levels
By the end of the course the students:

  • Will have a basic understanding of why and how countries tax multinational enterprises, and how corporate tax planning works’

  • Will have a basic understanding of the phenomenon of tax avoidance. Students will be familiar with the elements of tax systems used for tax avoidance, and they will be able to think and argue in an informed and relevant manner about the position of both countries and multinational enterprises in this field. They will also have a broad idea of the solutions presently debated by international organizations, supranational (European Union) organizations, countries and civil society to tackle tax avoidance.

  • Will have a basic understanding of the initiatives developed by international organizations and the European Commission to deal with tax avoidance (e.g. Base Erosion Profit Shifting (BEPS) Project, EU Standard of Tax Good Governance, Taxation of Highly Digitalized Business (Pillar 1) and Introduction of a Global Minimum Tax Rate (Pillar 2).

Assessment method

Regular examination
The grade for this course is based on a final, written exam at the end of the course. Depending on the number of students, we may choose to make the exam an oral exam instead of a written exam.

In addition a participation bonus of 0.5 may be earned. Whether or not the bonus will be granted is based on submission of assignments (through Brightspace).. Please note that participation is not mandatory; it is still possible to get the maximum grade for the course without the participation bonus.

A passing grade for the course is 5.5 or higher.

Students who fail to obtain a passing grade for the regular exam are entitled to a re-examination. A participation bonus is not carried over to the re-examination. The re-examination consists of an individual oral exam.

Regulation retake passed exams
In this course it is possible to retake an exam that has been passed (cf. art. and further of the Course and Examination Regulations) on the condition of a written exam. Students who have passed the exam may retake the final written assessment (test) of the course if they meet certain requirements.
