The Luxembourg SICAV-RAIF structure delivers a compelling solution for institutional investors and managers seeking a flexible, open-ended fund vehicle. By combining the characteristics of a variable capital investment company (SICAV) with the regulatory agility of the Reserved Alternative Investment Fund (RAIF) regime, the SICAV-RAIF offers rapid time-to-market, multi-compartment possibilities, and robust asset protection. This article analyses the core features, structuring options, tax treatment, and practical formation steps for this sophisticated fund type.
What is a Luxembourg SICAV-RAIF?
The Luxembourg SICAV-RAIF blends two powerful concepts under Luxembourg law. The SICAV is a variable capital investment company. It adjusts its share capital automatically as investors subscribe or redeem shares. The RAIF regime, introduced by the Law of 23 July 2016, enables the creation of alternative investment funds without direct authorisation or supervision by the CSSF. Instead, an authorised AIFM manages the SICAV-RAIF and assumes regulatory responsibility. As a result, sponsors can launch a SICAV-RAIF quickly, often within weeks.
Specifically, the RAIF regime restricts access to well-informed investors, including institutional and professional clients. The Law of 23 July 2016 governs the RAIF, while the Law of 10 August 1915 (“1915 Law”) provides the general corporate law framework for SICAVs. The combination enables the SICAV-RAIF structure to operate as an open-ended, multi-compartment fund platform. The vehicle can invest in all asset classes, including private equity, real estate, infrastructure, and debt. In addition, sponsors can create a SICAV-RAIF as an umbrella fund, with each sub-fund ring-fenced from others.
Moreover, the SICAV-RAIF enjoys strong contractual flexibility. The constitutional documents and offering memorandum define the investment strategy and governance, subject to AIFMD and the RAIF law. In turn, the AIFM ensures compliance with risk management, valuation, and disclosure obligations.

SICAV-RAIF vs SICAV-SIF: Which structure to choose?
Both the SICAV-RAIF and the SICAV-SIF offer variable capital, multi-compartment structures suitable for alternative assets. However, key differences exist in regulatory oversight, set-up speed, and ongoing obligations.
Regulatory oversight and authorisation
The SICAV-SIF requires approval and ongoing supervision by the CSSF. This process can extend the time-to-market and introduce additional compliance costs. In contrast, the SICAV-RAIF does not require CSSF authorisation. An authorised AIFM manages the SICAV-RAIF and handles regulatory compliance under AIFMD. As a result, sponsors can launch a SICAV-RAIF rapidly, provided they appoint an eligible AIFM.
Investment flexibility and eligible investors
Both vehicles target well-informed investors, as defined by Luxembourg law. The SICAV-RAIF, however, benefits from a wider investment scope. The law permits investment in all asset classes, including real estate, private equity, debt, infrastructure, and liquid securities. By contrast, the SICAV-SIF operates under the Law of 13 February 2007, which also allows broad investment policies but involves more regulatory reporting.
Cost and structuring factors
The SICAV-RAIF structure can reduce start-up costs and administrative burden compared to a SICAV-SIF. The absence of CSSF authorisation streamlines documentation and accelerates investor onboarding. Nevertheless, both structures require the appointment of an AIFM, depositary, and auditor. Specifically, the SICAV-RAIF suits sponsors prioritising speed and flexibility, especially for cross-border strategies. Meanwhile, institutional investors seeking additional regulatory comfort may favour the SICAV-SIF.
Multi-compartment structuring with SICAV-RAIF
The SICAV-RAIF enables the creation of umbrella funds with multiple compartments, each pursuing distinct strategies or asset classes. Article 50 of the Law of 23 July 2016 enshrines the principle of compartmentalisation. Each sub-fund holds segregated assets and liabilities. Creditors of one compartment cannot claim against the assets of another. As a result, sponsors can offer a suite of products within one legal entity, simplifying platform management and governance.
Each compartment may have different investment policies, fee structures, and investor bases. For example, a SICAV-RAIF umbrella can host separate sub-funds for private equity, real estate, and infrastructure. Moreover, sub-funds can launch or close independently, allowing managers to respond flexibly to investor demand.
Practical considerations for multi-compartment SICAV-RAIFs
- Sponsors must define each compartment’s rules in the issuing document and constitutional documents.
- Each sub-fund requires separate accounting and NAV calculation.
- Sub-funds may appoint dedicated investment advisors or managers, subject to overall AIFM oversight.
- Investors subscribe to shares or units issued by specific compartments, not the umbrella as a whole.
Additionally, the SICAV-RAIF model supports cross-border distribution to professional investors under AIFMD passporting. This approach enhances the platform’s scalability for global managers. In turn, managers can structure share classes (e.g., euro, USD, hedged) within each compartment to cater to diverse investor preferences.
In the context of asset protection, the ring-fencing of liabilities within each compartment increases creditor protection and operational clarity. This feature proves attractive for multi-strategy managers and institutional sponsors scaling their Luxembourg presence.
SICAV-RAIF tax treatment and subscription tax
The SICAV-RAIF benefits from a favourable tax regime. Luxembourg does not levy corporate income tax, municipal business tax, or net wealth tax on SICAV-RAIFs. Instead, the vehicle pays an annual subscription tax (taxe d’abonnement) at a standard rate of 0.01% of net asset value (NAV). The law calculates this on a quarterly basis. However, compartments investing in certain money market instruments or pension assets may qualify for full or partial exemption.
In addition, the SICAV-RAIF structure enjoys full tax neutrality for investors. Luxembourg does not withhold tax on distributions or capital gains paid to non-residents. The country grants SICAV-RAIFs access to many double tax treaties, especially where the fund invests through a local taxable subsidiary. This approach enhances after-tax returns for cross-border investors.
Furthermore, the RAIF may register for VAT on management and advisory services. However, Luxembourg generally exempts fund management fees from VAT. Managers should review the VAT status of ancillary services, particularly in the context of real estate or direct lending strategies.
Tax treatment for SICAV-RAIF real estate and private equity
When structuring SICAV-RAIF compartments for real estate or private equity, sponsors must consider the asset holding structure. Direct real estate investments may trigger local property taxes in the investment jurisdiction. Many managers use a SICAV-RAIF to hold shares in property-owning companies, improving treaty access and administrative efficiency. Similarly, private equity compartments often invest through holding vehicles or co-investment structures to optimise tax treatment and ring-fence liabilities.
For carried interest and performance fees, managers usually receive payments at the compartment level. Luxembourg tax law offers specific carried interest regimes for qualifying staff under the 2016 law. Therefore, sponsors should review the eligibility criteria for carried interest tax treatment before launch.
Establishing a SICAV-RAIF platform in Luxembourg
Forming a SICAV-RAIF involves several key steps, each requiring careful coordination among sponsors, service providers, and legal counsel.
1. Choice of legal form and constitutional documents
The SICAV-RAIF can take the form of a public limited company (SA), private limited company (S.à r.l.), or cooperative company (SCoSA) with variable capital. The 1915 Law governs the chosen legal form. Sponsors must draft the articles of association and issue an offering memorandum. These documents set out the investment policy, governance, compartment rules, and risk management approach.
2. Appointment of an authorised AIFM
Only an authorised AIFM may manage a SICAV-RAIF. The AIFM ensures compliance with AIFMD requirements, including risk management, liquidity, valuation, and reporting. The AIFM may be established in Luxembourg or another EU member state. The AIFM must appoint a depositary, auditor, and central administrator for the SICAV-RAIF.
3. Minimum capital and investor eligibility
The SICAV-RAIF must reach a minimum capital of EUR 1,250,000 within 12 months of launch. Only well-informed investors, as defined by the 2016 Law, may invest. These include institutional and professional investors, as well as certain high-net-worth individuals who certify their status.
4. Notarial deed and registration
A Luxembourg notary must notarise the articles of association. The SICAV-RAIF must then register with the Luxembourg Trade and Companies Register (RCS). The vehicle does not require CSSF approval, but the AIFM must notify the CSSF of the launch. Once registered, the SICAV-RAIF can begin operations and accept subscriptions.
5. Ongoing compliance and reporting
The AIFM handles ongoing compliance, including annual audits, NAV calculation, and regulatory reporting under AIFMD. The SICAV-RAIF must update its offering memorandum and constitutional documents for material changes. Additionally, the AIFM coordinates anti-money laundering (AML) and know-your-customer (KYC) checks for investors. In turn, this ensures compliance with Luxembourg and EU standards for alternative funds.
Sponsors should engage specialised Luxembourg counsel and fund administrators experienced in SICAV-RAIF formation. Early coordination with the AIFM, depositary, and auditors streamlines onboarding and minimises launch delays. In practice, the SICAV-RAIF structure enables rapid platform deployment and efficient scaling for multiple asset strategies.
