This article examines whether the global minimum tax (Pillar Two) could infringe upon the principles of protecting acquired rights and legitimate expectations. It argues that implementing a top-up tax under Pillar Two might violate promises made by governments to multinational enterprises, particularly by revoking previously granted tax incentives. The article delves into the fact that the possibility of utilizing pre-GloBE deferred tax assets and the substance-based carveout may not be enough to prevent such infringements. It explores potential legal avenues for MNEs to challenge the QDMTT, IIR, and UTPR. The article concludes by emphasizing that the lack of robust safeguards for these but also other fundamental rights in the Pillar Two model rules raises serious questions about the legitimacy and longterm sustainability of a global tax regime.
