On December 19, 2024, the Luxembourg Parliament approved Bill No.8396 which amends the Luxembourg Global Minimum Tax Law (Law A864 which transposes the Pillar 2 rules as provided in the EU Minimum Tax Directive). The amendments apply for Fiscal Years ending on or after December 31, 2023.
This follows the original draft law issued on June 12, 2024, (draft law amending the law of 22 December 2023 on the minimum effective taxation for multinational enterprise groups and large domestic groups) which provided for a number of amendments in the February 2023, July 2023 and December 2023 OECD Administrative Guidance. On October 31, 2024 additional amendments were made to the draft legislation to incorporate elements from the June 2024 OECD Administrative Guidance, which will also have an impact on the application of Luxembourg’s QDMTT.
QDMTT Amendments
The amendments that impact on the QDMTT include:
(1) Article 44(5) of the Law excludes taxes incurred by CFC’s, Hybrids (as provided in the July 2023 OECD Administrative Guidance) and taxes on distributions (aside from domestic withholding tax). The December 2024 Amendment Law also extends the restriction to Reverse Hybrids as stated in Article 5.6.2 of the June 2024 OECD Administrative Guidance.
(2) Article 44(6) of the Law provides that instead of using the UPEs accounting standard, MNEs calculate GloBE income for QDMTT purposes using Luxembourg Accounting Standards or IFRS.
Article 11 of the December 2024 Amendment Law provides that the IFRS to be used in the event that several admissible financial accounting standards applicable in Luxembourg are used by the Constituent Entities of the Group, is the IFRS as adopted by the European Union in accordance with Regulation (EC) No 1606/2002 of the European Parliament and of the Council of 19 July 2002 on the application of international accounting standards.
(3) Article 11 of the December 2024 Amendment Law provides that where all the Constituent Entities in the jurisdiction use Luxembourg GAAP and the euro as their functional currency, the QDMTT requires the relevant computations in euros.
However, if not all Constituent Entities in the jurisdiction use euros as their functional currency, the Filing Constituent Entity may make a Five-Year Election to undertake the QDMTT computations for all Constituent Entities in the jurisdiction either:
– in the presentation currency of the Consolidated Financial Statements; or
– in euros.
(4) Article 11 of the December 2024 Amendment Law applies the initial phase of international activity exemption for QDMTT purposes.
(5) The June 2024 OECD Administrative Guidance provides various options to jurisdictions that have implemented a QDMTT in respect of securitisation vehicles:
(i) application of the jurisdiction’s QDMTT to securitisation vehicles without any specific adjustment of the rules;
(ii) exclusion of securitisation vehicles from the scope of the QDMTT; or
(iii) inclusion of securitisation vehicles in the scope of the QDMTT while providing that the amount of QDMTT that has been determined for a securitisation vehicle is imposed on another Constituent Entity located in the same jurisdiction and forming part of the same MNE Group.
Article 12(3) of the December 2024 Amendment Law applies option (iii). However, if there are no other constituent entities located in Luxembourg, the amount of QDMTT for a securitisation vehicle is allocated for the purposes of the payment of the QDMTT to the securitisation vehicle itself.
Amendments for the OECD Administrative Guidance
The amendments are comprehensive and will ensure Luxembourg’s Global Minimum Tax Law now includes most aspects of the OECD Administrative Guidance issued to date, although some of the amendments are subject to further Grand Ducal Regulations.
