Pillar Two establishes a jurisdictional effective tax rate of at least 15% to multinational groups with consolidated revenue of at least €750 millions. Global agreement has been reached to bring these rules into law and the OECD has released model rules, commentary and administrative guidance. EU member states have unanimously adopted the EU Council Directive 2022/2523 of 14 December 2022 on ensuring a global minimum level of taxation for multinational enterprise groups and large-scale domestic groups in the European Union, known as the EU Pillar Two Directive or the GloBE (Global anti-Base Erosion). At EU level, the rules had to be implemented by 31 December 2023. Many non-EU countries have also implemented Pillar Two in their domestic rules.
On 20 December 2023, the Luxembourg Parliament voted to approve the Pillar Two law transposing the EU Pillar Two Directive. The law entered into force as from fiscal years starting on or after 31 December 2023. The Income Inclusion Rule (IIR) and the Qualified Domestic Minimum Top-up Tax (QDMTT) became effective for fiscal years starting on or after 31 December 2023, whereas the Undertaxed Profits Rule (UTPR) became effective for fiscal years starting on or after 31 December 2024. The Luxembourg Pillar Two Law was amended in December 2024 to incorporate the latest administrative guidance issued by the OECD and clarify some important principles which could be relevant for Luxembourg businesses impacted by the rules.
