Luxembourg
The European home of institutional funds and holding SOPARFIs.

Luxembourg is the European institutional-fund capital — €5 trillion in AUM, second only to the US globally. The SOPARFI holding regime, the RAIF and SIF fund vehicles, and unmatched double-tax-treaty and EU-directive access make it the default European structuring jurisdiction for institutional capital.
The country is small, expensive and demanding — this is not a jurisdiction for lightweight structures. But for institutional funds, cross-border holding groups and IP financing vehicles, few jurisdictions match its combination of tax efficiency, treaty access and reputational quality.
Where Luxembourg fits
- RAIF/SIF funds
- SOPARFI
- SPVs
Banking landscape
Luxembourg banking is deep for institutional funds and private banking. Every major European bank has a Luxembourg presence; the depth of custody, administration and depositary services is unmatched in Europe.
Tax & reporting
24.94% combined effective corporate and municipal tax on ordinary trading income. The SOPARFI regime exempts qualifying dividends and capital gains from participation exemption. Full EU-directive access on cross-border interest, royalties and dividends.
Substance & register visibility
Luxembourg substance is real — office, local directors, board meetings held in-jurisdiction, decisions taken there. ATAD, DAC6, unshell (ATAD3) and the OECD Pillar Two rules all interact with Luxembourg structures; substance failures now have real consequences.
When to pick this jurisdiction
Pick Luxembourg for institutional fund domiciles (RAIF, SIF, SICAV), for European holding groups where treaty and EU-directive access is critical, or for IP financing structures where the participation exemption and treaty network matter.

Questions we hear on every Luxembourg intake.
- What is a SOPARFI?
- A Société de Participations Financières — a Luxembourg holding company that benefits from the participation exemption on qualifying dividend income and capital gains from qualifying subsidiaries. The workhorse of European cross-border holding structures.
- RAIF or SIF?
- A RAIF (Reserved Alternative Investment Fund) launches without prior CSSF approval — faster and more flexible, but requires an authorised AIFM. A SIF is CSSF-supervised directly and suits fund structures where regulatory badge matters to investors.
- What is ATAD3 (unshell)?
- The EU Anti-Tax-Avoidance Directive 3 introduces minimum substance requirements for EU shell entities. Entities failing the tests lose access to double-tax-treaty and EU-directive benefits. We design against ATAD3 from the outset.
