Luxembourg's tax authority has reminded in-scope companies of their obligation to register and file under the Pillar Two global minimum tax rules, warning that penalties will follow non-compliance.
The reminder targets multinational and domestic groups that fall within the scope of Luxembourg's implementation of the OECD's Pillar Two framework, which applies to groups with annual consolidated revenue of at least €750 million. Luxembourg transposed the EU Minimum Tax Directive into domestic law, bringing the qualified domestic minimum top-up tax and the income inclusion rule into force for fiscal years beginning on or after 31 December 2023.
The authority's notice underscores that both registration and filing deadlines are enforceable. Groups that have not yet registered or that are approaching filing deadlines should treat this as an urgent prompt to act. The source material does not specify the precise penalty amounts or the exact deadlines referenced in the warning, so affected entities should consult the Luxembourg tax authority's official communications directly for those details.
