The emergence of global tax governance was triggered by common tax problems, which are now still being faced by international society of nation-states. In the creation of this framework, international institutions have been playing a major role. One of these institutions is the World Bank (Bank). However, those who write about the virtues and vices of the main creators of the framework usually disregard the Bank. This article, therefore, argues that this disregard is not justified because the Bank has also been playing a prominent role. Since two informal decisions taken in the past have contributed to this position of the Bank, the article gives in addition to it answers to the following two related questions: whether these informal decisions of the Bank were legal and if so, what implications, if any, they have for the Bank’s legitimacy.

The international tax system is the result of the interaction of different actors who share the responsibility for its integrity. States and multinational corporations both enjoy to a certain extent freedom of choice with regard to their tax behaviour – which entails moral responsibility. Making, interpreting and using tax rules therefore is inevitably a matter of exercising responsibility. Both should abstain from viewing tax laws as a bunch of technical rules to be used as a tool without any intrinsic moral or legal value. States bear primary responsibility for the integrity of the international tax system. They should become more reticent in their use of tax as regulatory instrument – competing with one another for multinationals’ investment. They should also act more responsibly by cooperating to make better rules to prevent aggressive tax planning, which entails a shift in tax payments from very expert taxpayers to other taxpayers. Here, the distributive justice of the tax system and a level playing field should be guaranteed. Multinationals should abstain from putting pressure on states and lobbying for favourable tax rules that disproportionally affect other taxpayers – SMEs and individual taxpayers alike. Multinationals and their tax advisers should avoid irresponsible conduct by not aiming to pay a minimalist amount of (corporate income) taxes – merely staying within the boundaries of the letter of the law. Especially CSR-corporations should assume the responsibility for the integrity of the tax system.

The aim of this article is to examine the differences in perception of ‘fairness’ between developing and developed countries, which influence developing countries’ willingness to embrace the Base Erosion and Profit Shifting (BEPS) proposals and to recommend as to how to overcome these differences. The article provides an introduction to the background of the OECD’s BEPS initiatives (Action Plan, Low Income Countries Report, Multilateral Framework, Inclusive Framework) and the concerns of developing countries about their ability to implement BEPS (Section 1); a non-exhaustive overview of the shortcomings of the BEPS Project and its Action Plan in respect of developing countries (Section 2); arguments on why developing countries might perceive fairness in relation to corporate income taxes differently from developed countries (Section 3); and recommendations for international organisations, governments and academic researchers on where fairness in respect of developing countries should be more properly addressed (Section 4).
