Objectives

The first objective consists of demonstrating the enormous current importance of international tax law, given the growth in cross-border businesses and the need to regulate, in particular, contact that arises with different fiscal systems.
The international tax law curricular unit allows students to understand the impact that taxation has upon the movement of goods, services and capital, learning how sovereign states (with Portugal as a starting point) seek to reconcile their financial interests with the need to avoid double taxation and situations of tax evasion.
In addition to a theoretical framework on international tax law and, in particular, the limitations of fiscal sovereignty, students address issues of interpretation and qualification and different models of international taxation, in order to ensure that they identify the rationale for solutions adopted at the legislative level, both domestic and in terms of double tax conventions, and gain the capacity to resolve specific problems that arise in conciliating domestic, EU and DTC rules.
Finally we encourage students to use knowledge obtained in the study of other areas of law (for instance, contract law, company law, EU law, intellectual property, as well as international public and private law) in analysing the situations with which they are confronted during the duration of the course.
