Tax competition among modern states

In recent years, a counter-trend phase has begun with respect to the process of tax competition between States, and the attention of international organizations (OECD, G20, G7, EU) has focused on the risks deriving from competition between the various state sovereignties. The emerging idea is that States must cooperate to achieve common development, economic and social objectives, even limiting, at least partially, their own tax sovereignty through the implementation of legal models formulated in international agreements in order to effectively pursue the erosion of the tax base. and internal taxation. The guidelines for intervention consist in the definition of taxation models for multinationals to be imposed with homogeneity on an international basis and in the pursuit of global transparency of the financial positions of taxpayers abroad. The fight against harmful tax competition therefore seems to constitute the basis for the launch of a new international tax order, characterized by a self-limitation of the fiscal sovereignties of the States and the relevance of international agreements (multilateral and/or bilateral).
