At the centre of the European legal system is the concept of an internal market, defined in Article 26 of the Treaty on the Functioning of the European Union (hereinafter, TFEU) as "an area without frontiers in which the free movements of good, persons and capital is ensured in accordance with the provisions of the Treaties". State aid prohibition, together with the prohibition on cartel agreements and abuse of dominant market position, is aimed at ensuring the protection of the internal market. Traditionally, in the field of State aid law, there has always been an attempt to strike a balance between two conflicting demands which are, on the one hand, the protection of free competition and the internal market and, on the other, the protection of national sovereignty and autonomy of the Member States regarding the choices of internal economic and fiscal policy. While it is true, in fact, that direct taxation falls within the competence of the Member States, it is equally true, and peacefully accepted, that the Member States must exercise their fiscal competence in compliance with Union law1. 1 To understand European competence in the area of direct taxation, it is relevant to examine the principles governing European competences. The fundamental of European competences is laid down in Article 5, which establishes the principles of conferral, subsidiarity and proportionality. Under the principle of conferral, the Union may act only within the limits of competences conferred upon it by the Member States in the Treaties to attain the objectives set put therein. Competences not conferred upon the Union in the Treaties remain with the Member States. The two other principles, that are key to tax harmonization, limit the exercise of legal competence. The principle of subsidiarity requires that the European Union execute its competence only if and in so far as the objectives of the proposed action cannot be sufficiently 1 In a multilevel context, the definitive consolidation of the single market required more and more the exercise of a direct action on national scales by the European institutions. This implied the breaking of the traditional intervention schemes based on the competence-attribution binomial 2 . In recent years, in fact, the European Institutions began to implement their coordination action through the expansive exercise of skills and powers already expressly attributed by the Treaties in relation to distinct sectors of intervention. Beyond the strictly political critical issues, it immediately became evident that the European approach led to an inevitable compression of the taxing power of the Member States and the relative territorial autonomies. In this sense, the search for a tax regime common to the Member States of the European Union seemed increasingly inseparable from European control over State aid 3. During the years, in fact, the continue interaction between State aid discipline and national tax legislation have contributed to transform the prohibition on selective aid under Article 107 (1) TFEU, not only a powerful policy tool in the hands of the European Commission, but also a substantial constraint to tax achieved by the Member States. The principle of proportionality requires that European action not exceed what is necessary to achieve European objectives. There are a few additional principles that indirectly affect European competence in the field, both direct and indirect, taxation and potentially limit the tax sovereignty of Member States. Among these, the prohibition of direct and indirect discriminatory taxation of foreign products and direct and indirect fiscal protection of domestic production play an important role in preventing protectionism (Article 110 TFEU). The inverse principle is the prohibition of direct and indirect tax subsidies on products exported to another Member State (Article 111 TFEU). 2 EUSEPI S., L’incidenza della normativa in tema di aiuti di Stato sull’autonomia tributaria degli Stati membri alla luce del nuovo modello di finanziamento, in Riv. dir. trib., 2, 2016. 3 JURY F., Le règime des aides d'Etat: un moteur efficace de la politique fiscale européenne, in Revue del'Unione Europèenne, 620, 2018, 427. 2 sovereignty in the Member States of the European Union4. The Commission began to deal systematically with the applicability of prohibition on State aid to taxation, no longer considering it only one of the possible profiles inherent in the prohibition of State aid, but as the precise objective of its action, orienting the extension of the scope of this prohibition to the achievement of further and different objectives, essentially the approximation of direct taxes and the fight against erosion of the tax base 5 . This is closely connected with the fact that Article 115 TFEU, that is the legal basis underlying the approximation
