How we act
Coordination by Hart David Carson LLP; local law advice by locally admitted counsel.

Luxembourg is the center of Europe's cross-border fund industry and a widely used holding-company jurisdiction inside the EU single market. It is prized for political and legal stability, an extensive treaty network, and financial infrastructure built over decades for the cross-border investor.

The pull is structural. As an EU member state with a civil-law tradition, Luxembourg combines single-market access with the EU passporting that lets a UCITS or an AIFMD-regulated alternative fund be distributed across the bloc from one domicile. That access, paired with a deep bench of management companies, depositaries, administrators, and private banks, is why it remains the default home for pan-European fund distribution and for the holding and financing platforms that sit above multinational groups.

The same depth serves private-equity, debt, and real-asset strategies that need partnership flexibility, and holding groups that need treaty access and a participation-exemption regime. The educational picture below is accurate as a matter of Luxembourg law; the substantive advice on any given structure, and any regulated activity, is carried by locally admitted avocats and licensed Luxembourg entities. Hart David Carson acts as facilitator and project lead and does not maintain an office in Luxembourg.

Capabilities we coordinate

The vehicles, accounts, and regimes most often at the center of a Luxembourg matter, coordinated with locally admitted avocats, notaries, and licensed entities.
01

Company & Entity Formation

We frame the vehicle with locally admitted avocats and a notary. A holding or financing platform is usually a SOPARFI, a fully taxable company drawing on the participation exemption, formed as a public company, the SA, or a private limited company, the Sàrl. Fund structuring runs on the common limited partnership, the SCS, and the special limited partnership, the SCSp.

Incorporation runs through a Luxembourg notary, with the deed and statutes executed before entry in the Registre de Commerce et des Sociétés (RCS) under the amended Law of 10 August 1915 on commercial companies. Ultimate beneficial owners are recorded in the RBE.

02

Trusts & Foundations

Luxembourg has no domestic trust, so we coordinate a family's wealth-holding layer with Luxembourg avocats and licensed fiduciaries around what its law offers. It has ratified the Hague Trust Convention and recognizes foreign trusts. The fiducie, a fiduciary contract, and contractual arrangements are functional alternatives, and the private wealth management company, the SPF, is used to hold personal investment assets.

Where a foreign-law trust is the right instrument, we coordinate Luxembourg avocats and licensed fiduciaries alongside trustees admitted in the governing-law jurisdiction, so the wealth, succession and philanthropy objectives are met without overstating what Luxembourg law itself provides.

03

Banking & Accounts

Luxembourg is a major private-banking, custody and depositary center with full SEPA and euro-system access, serving fund, holding and private-client mandates at scale.

Onboarding is rigorous. Expect substance, beneficial-ownership, and source-of-wealth diligence aligned to the EU AML directives, with closer scrutiny of complex ownership chains and higher-risk profiles. We help assemble a clean, well-documented file and introduce banking and depositary relationships from our partner network; the account relationship itself is held with the licensed institution.

04

Funds

We settle the regime with the avocat and ManCo; it fixes investor base and timing. Regimes run from UCITS to the Reserved Alternative Investment Fund, the RAIF, with the Specialised Investment Fund, the SIF, and the SICAR between, each cast as a SICAV, SICAF or partnership vehicle under the 2010 Law, the SIF Law and the RAIF Law of 2016.

  • UCITS are passportable retail funds for pan-European distribution.
  • SIF / SICAR are supervised vehicles for well-informed and risk-capital investors.
  • RAIF is manager-regulated, with no direct product approval, and reaches the market faster through an authorized AIFM.

The CSSF authorizes and supervises managers under the EU UCITS and AIFMD frameworks, with EU passporting available through an authorized management company.

05

Regulatory & Licensing

The CSSF licenses and supervises banks, investment firms, fund managers and depositaries, applying EU prudential and conduct standards; the Commissariat aux Assurances supervises insurance.

AML/CFT obligations derive from the EU directives as implemented in Luxembourg law, and the beneficial-ownership register (RBE) records UBOs. Matters before the CSSF are run through locally admitted avocats and licensed management companies; we coordinate the engagement and do not ourselves speak for the regulator.

06

Tax & Treaty Posture

A SOPARFI only works if the participation exemption applies, so we coordinate the holding conditions with Luxembourg tax advisers before the platform is built. Luxembourg levies corporate income tax, municipal business tax and a net wealth tax, but the participation-exemption regime can exempt qualifying dividends and capital gains, and qualification turns on the size and holding period of each participation.

It maintains an extensive double-tax treaty network, applies the EU directives, and participates in the OECD Common Reporting Standard, FATCA, and the BEPS and Pillar Two minimum-tax measures. Tax structuring is developed with Luxembourg counsel and advisers and is jurisdiction-specific; this page is educational and is not tax advice.

On the ground

Government affairs &
facilitators in Luxembourg.

Engagement with the CSSF and the tax authorities is a routine part of fund launches and holding structures in Luxembourg, and it is conducted through licensed actors, transparently and on the record. We coordinate that engagement; we do not stand in for the regulator or the local professional.

Our facilitation and partner network spans the people and entities a Luxembourg matter actually runs on. Locally admitted avocats and licensed Luxembourg entities carry the regulated and substantive roles, while we hold the project together across time zones.

How we coordinate a matter here

Hart David Carson can help frame a Luxembourg fund or a SOPARFI holding structure, introduce the appropriate management company, avocat, and administrator, and coordinate the launch from start to finish.

In practice that means scoping the structure against your commercial and tax objectives, selecting the right vehicle (a UCITS, SIF, RAIF or a SOPARFI holding company) with input from local advisers, and assembling the team: the ManCo or AIFM, a Luxembourg avocat, a notary for incorporation, a depositary and an administrator. We drive the timeline, keep the documentation coherent, and manage the registry, onboarding and CSSF-facing workstreams so nothing falls between providers.

Throughout, the regulated relationship and the substantive Luxembourg legal advice sit with locally admitted avocats and licensed entities. Hart David Carson acts as facilitator and project lead alongside Luxembourg-admitted counsel. One partner is accountable to the cross-border client for the whole engagement, and that partner does not substitute for the local professional.

Frequently asked

Common questions on structuring in Luxembourg.
Why do international clients choose Luxembourg for fund and holding structures?

Luxembourg is Europe's main cross-border fund domicile and a widely used EU holding-company jurisdiction, prized for political and legal stability, an extensive double-tax treaty network, and deep financial infrastructure. As an EU member state it offers single-market access and EU passporting for UCITS and AIFMD-regulated products, which makes it the natural hub for pan-European distribution and for holding and financing platforms. The substantive legal advice and any regulated activity are carried by locally admitted avocats and licensed Luxembourg entities; Hart David Carson acts as facilitator and project lead.

What entities are typically used in Luxembourg?

The SA, a public company, and the Sàrl, a private limited company, are the corporate forms; the SOPARFI is a fully taxable holding and financing company using the participation exemption. The SCS and SCSp, the common and special limited partnerships, carry fund structuring, with vehicles cast as a SICAV or SICAF under the SIF, SICAR or RAIF regimes. Incorporation runs through a Luxembourg notary and the Registre de Commerce et des Sociétés, the RCS, so the notary date sets timing.

Does Luxembourg recognize trusts?

Foreign trusts, yes; a domestic trust, no. Luxembourg, a civil-law jurisdiction, has no trust law of its own, but it has ratified the Hague Trust Convention and recognizes foreign trusts. Functional alternatives include the fiducie, a fiduciary contract, and the private wealth management company, the SPF, used to hold personal investment assets. A foreign-law trust holding Luxembourg assets therefore needs advisers in two jurisdictions, so we coordinate Luxembourg avocats and fiduciaries alongside trustees admitted in the governing-law jurisdiction.

Who regulates funds and financial activity in Luxembourg?

The Commission de Surveillance du Secteur Financier (CSSF) licenses and supervises banks, investment firms, fund managers and depositaries, applying EU prudential and conduct standards; the Commissariat aux Assurances supervises insurance. AML/CFT obligations derive from the EU directives as implemented in Luxembourg law, and ultimate beneficial owners are recorded in the Registre des Bénéficiaires Effectifs (RBE). We coordinate matters before the CSSF through locally admitted avocats and licensed management companies and do not ourselves speak for the regulator.

How is Luxembourg taxed, and what is the participation exemption?

Luxembourg levies corporate income tax, municipal business tax and net wealth tax, but the participation-exemption regime can exempt qualifying dividends and capital gains, the basis of the SOPARFI holding platform. Each acquisition is sized and held to meet the exemption's conditions. Luxembourg has an extensive treaty network, applies the EU directives, and participates in the OECD Common Reporting Standard, FATCA, and the BEPS and Pillar Two minimum-tax measures. Luxembourg counsel and advisers develop the structuring; nothing here is tax advice.
