The Seminar in Tax Law (Fachseminar aus Steuerrecht) will be held in English only and will be conducted in cooperation with the University Amsterdam. In that context a joint video conference shall take place in which it is intended that students of both universities lead simulated tax treaty negotiations. In order to prepare for this event it is essential that all participants are familiar with the OECD Model Tax Convention. Participants therefore should make a “self-test” in advance of the course in order to check whether he/she is in a position to give brief explanations with regard to each of the Articles of the OECD Model Tax Convention in the English language. The preparation is necessary to ensure discussions on a high academic level.
