The Section Tax Law of the Leiden Law School has a vacancy for

PhD Candidate Taxation
 (1,00 FTE)  
Vacancy number 21-519 9835


The research project Tax Transparency of the Section Tax Law of the Leiden Law School has a PhD position in Tax Law and welcomes proposals (see application section below) that fit in the programme of this project. The project addresses the international problem of tax avoidance by multinational companies and related harmful tax policy competition between countries. This problem is a constant focus of public debate. The project fits within the strong social connection of the Section Tax Law of the Leiden Law School by providing solutions for social problems and a more just society.


Research Project Tax Transparency

The Tax Transparency project considers that harmful tax policy competition and undesirable tax avoidance can only be effectively addressed if countries work together. However, in practice, it has proven difficult to get this cooperation off the ground, even within the European Union, because of the perceived conflicting national interests of countries. With increasingly open borders (globalisation), countries are also increasingly using their tax systems to create an attractive business environment for multinational companies to attract economic activity, employment and innovation. The project investigates the problem that countries – focusing on EU Member States and European institutions – are not very open and transparent about the existence and role of the double bind in combating tax avoidance on the one hand and excessive tax policy competition on the other hand.


The project uses innovative approaches to empirically map how Member States and European institutions work together in different fora to address unfair taxation, by obtaining unique primary data from Member States and European institutions, complemented with interviews with tax policymakers. To ensure a comprehensive approach, the project considers other relevant disciplines – e.g. economics and political science – in addition to law.

The project translates its scientific research for the benefit of society – including the investigative journalism, policymakers, politicians, and non-governmental organizations – by organizing seminars, workshops and dialogues.

Our organisation
With over 5,000 students and 450 members of staff, Leiden Law School is one of the largest faculties in the Netherlands.

It does so by working with talented people and stimulating and supporting them in their professional and personal ambitions. The Faculty is housed in the beautifully restored Kamerlingh Onnes Building on the Steenschuur in Leiden. Working for the Leiden Law School means working in an inspiring scientific environment.

The Tax Transparency project is part of the research programme Limits of Tax Jurisdiction of the Section Tax Law. This project investigates the substance and effectiveness of tax law and policy developments at national (Dutch), supranational (EU), and international level (OECD; e.g. BEPS project) in tackling tax avoidance. It also investigates the role of tax advisors, multinational companies, and tax administrations in these developments. For more information about this research programme, see here.
