On 28 August 2026, the Luxembourg Administration des Contributions Directes (ACD) officially launched the pilot phase of its Enhanced Cooperative Compliance Program (ECCP), aligning with the OECD’s Guidance on Cooperative Compliance and the global shift towards real-time tax transparency. The program targets qualifying large taxpayers—typically multinational enterprises with significant cross-border operations and a robust tax governance framework. Participants benefit from a dedicated relationship manager, accelerated ruling processes, and enhanced certainty on complex tax positions through early engagement. The pilot operates under a formal Cooperative Compliance Agreement requiring real-time disclosure of material tax risks, annual tax control frameworks, and adherence to the OECD’s International Compliance Assurance Programme (ICAP) standards. The ACD will evaluate the pilot’s effectiveness through 2027 before potential full-scale implementation. This initiative complements Luxembourg’s commitment to the BEPS Action 13 (Country-by-Country Reporting) and Pillar Two minimum taxation regime. The legal basis derives from the Law of 21 December 2023 amending the General Tax Law (Loi générale des impôts) to introduce cooperative compliance mechanisms.
Key Takeaways
- Eligibility and Entry Criteria: The pilot is open to large corporate groups with consolidated revenues exceeding EUR 750 million, a demonstrated history of tax compliance, and an established tax control framework. Applicants must undergo a rigorous pre-qualification assessment evaluating their tax risk management maturity and willingness for proactive disclosure. The ACD requires a Tax Control Framework (TCF) self-assessment aligned with the OECD’s Building Block 4 (tax risk management and control). Groups must also demonstrate that their tax strategy is approved at board level and integrated into enterprise risk management.
- Operational Benefits and Obligations: Accepted participants gain access to a dedicated ACD case team, binding advance pricing agreements (APAs) on a fast-track basis, and a no-surprise principle for audit adjustments. In return, they must submit a Tax Control Framework Report annually, disclose uncertain tax positions in real time, and permit periodic ACD reviews of their transfer pricing documentation. The program includes a dispute prevention mechanism where the ACD provides non-binding views on proposed transactions within 30 days, reducing litigation risk. Participants also receive priority access to the Mutual Agreement Procedure (MAP) for double taxation disputes.
- Strategic Alignment with International Standards: The ECCP mirrors the OECD’s ICAP and the EU’s DAC 7 directive on digital platform reporting, positioning Luxembourg as a proactive jurisdiction for cooperative tax governance. Multinationals should assess whether participation reduces overall compliance costs and mitigates double taxation risks under Pillar Two. The ACD has signaled that successful pilot participants may receive reduced audit frequency and streamlined documentation requirements for future fiscal years, providing a tangible return on investment in tax governance infrastructure.
