Approaches of fighting with tax havens in the OECD countries

Overseas financial centers, which are called tax havens, attracting foreign investors with very low tax rates and tax conveniences, and offering tax evasion and tax avoidance opportunities, have attracted attention in recent years. Tax havens, reduce the tax revenues of the countries, cause erosion in the base and harm the macroeconomic balances of the countries. Considerable international studies are carried out on the theme of "tax competition" against the practices made by tax haven countries. These studies are mainly carried out within and under the leadership of the Organization for Economic Development and Cooperation(OECD). Based on the assumption that the OECD includes both developed and developing countries and that OECD data can be accessed more easily, it was considered appropriate to consider the studies conducted on the fight against tax havens. In the context of developed and developing countries, it is seen that developed countries stand out in the studies within the scope of the fight against tax havens. As part of the cooperation, the OECD reported that the global corporate tax agreement, also known as the global tax agreement, has been adopted by close to 140 countries and that companies will be subject to taxation of at least 15% in the countries where they operate.
