The use of accounting information in the tax base in the Pillar 2 global minimum tax: a discussion of the rules, potential problems, and possible alternatives

In this paper, I provide a high-level, non-technical review of how accounting information is used in Pillar 2 and what this means for the tax base. In addition, I discuss potential problems of using accounting data explicitly in a minimum tax and then, specifically, as the starting point for the computation of the income measures in Pillar 2. I then discuss several alternative solutions that may be simpler – or at least no more complex – and, importantly, pose fewer problems in terms of the quality of financial accounting information and the information available to capital markets.
