Luxembourg

A small EU member state with disproportionate weight in cross-border holding and asset-management structures. The SOPARFI corporate vehicle, the SPF family wealth vehicle, the lowest EU standard VAT, the former Luxembourg Freeport (now the Luxembourg High Security Hub), and an enormous fund industry combine to make Luxembourg a central node in European private-wealth structuring.

Why this jurisdiction matters

Luxembourg is in the EU and the eurozone, so its entities have full EU passport rights for funds, banking, and corporate purposes. It combines EU access with a tax regime favorable to holding companies under the participation exemption. Luxembourg undertakings for collective investment held about €6.2 trillion in net assets at 31 March 2026 (CSSF), and ALFI puts total fund assets, including alternative funds, at more than €8 trillion. It is Europe’s largest fund domicile and the second-largest in the world after the United States.

The relevant tax regime

Registration or residency mechanics

SOPARFI: Luxembourg société anonyme or société à responsabilité limitée under standard corporate law, with substance in Luxembourg. SPF: established under the law of 11 May 2007; investment activity restricted to financial assets. Luxembourg High Security Hub (the Luxembourg Freeport until its 2021 rebranding): a privately owned high-security storage facility next to Findel airport, operating under Luxembourg customs supervision. Founder Yves Bouvier sold his shareholding in 2024 to his former partner Olivier Thomas, who became sole shareholder.

Reporting and disclosure

CRS and DAC6 (EU mandatory disclosure rules) participant. Beneficial-ownership register (RBE): general public access was suspended after the CJEU’s November 2022 judgment in WM and Sovim (C-37/20 and C-601/20). Access is now limited to authorities, obliged entities and persons with a legitimate interest. FATCA Model 1 IGA in force.

The substance question

Luxembourg has implemented EU anti-tax-avoidance rules (ATAD I and II), the principal purpose test in tax treaties, and substance requirements for holding companies. Substance — directors, premises, management decisions — is required to claim treaty and EU directive benefits.

Recent changes

Pillar Two minimum tax for large groups (from 31 December 2023). CIT rate cut to 16% from 2025. The proposed ATAD III (“Unshell”) Directive was abandoned when ECOFIN dropped it in June 2025 and the Commission later withdrew it; substance concerns are expected to be addressed through DAC reform instead. RBE access was restricted after the 2022 CJEU ruling. Figures as of October 2026.
