What is a Luxembourg SICAV-RAIF?
The Luxembourg SICAV-RAIF delivers a highly flexible structure for institutional and professional investors. This vehicle combines the variable capital company (SICAV) model with the Reserved Alternative Investment Fund (RAIF) regime. The SICAV-RAIF structure enables open-ended or closed-ended investment strategies, which means investors can subscribe or redeem shares according to the fund’s rules. As such, asset managers can address a broad range of asset classes, including private equity, real estate, infrastructure, and debt.
The Luxembourg Law of 23 July 2016 on RAIFs, together with the Law of 10 August 1915 on commercial companies, provides the legal basis for SICAV-RAIFs. The RAIF does not require direct authorisation or supervision by the CSSF. Instead, an authorised Alternative Investment Fund Manager (AIFM) manages the SICAV-RAIF and ensures ongoing regulatory compliance. This model streamlines the launch process and reduces regulatory delays compared to structures such as SICAV-SIF or SICAV-SICAR.
In practice, the SICAV-RAIF appeals to fund promoters seeking rapid time-to-market and operational flexibility. It also supports sophisticated structuring, including umbrella and multi-compartment platforms. The open-ended RAIF Luxembourg model is particularly attractive for strategies requiring regular capital inflows or redemptions, such as real estate or private equity funds with staged capital calls.

SICAV-RAIF vs SICAV-SIF: Which structure to choose?
Both the SICAV-RAIF and SICAV-SIF offer umbrella fund platforms and variable capital. However, their regulatory processes and investor targeting differ significantly. The SICAV-SIF (Specialised Investment Fund) requires authorisation and ongoing supervision by the CSSF. As a result, SICAV-SIFs face longer setup times and more compliance administration.
In contrast, the SICAV-RAIF launches without direct CSSF approval. Instead, the AIFM assumes direct responsibility for regulatory compliance and risk management. Consequently, the SICAV-RAIF shortens the time-to-market, often allowing launch within weeks after notarial incorporation. For this reason, fund managers with pressing investment windows or cross-border mandates frequently choose the SICAV RAIF structure.
Both structures restrict access to well-informed, professional, or institutional investors. Nevertheless, the SICAV-RAIF may offer more agility for innovative or niche strategies. In turn, the SICAV-SIF sometimes appeals to investors preferring direct regulatory oversight or established CSSF relationships. Asset managers should weigh investor expectations, product strategy, and operational requirements when choosing between SICAV-RAIF and SICAV-SIF.
The SICAV-RAIF also fits seamlessly with alternative asset classes. Specifically, many private equity and real estate sponsors now favour the variable capital RAIF for its quick launch and AIFMD passporting.
Multi-compartment structuring with SICAV-RAIF
The SICAV-RAIF supports multi-compartment and umbrella structures, enabling asset managers to run several sub-funds under a single legal entity. Each compartment has ring-fenced assets and liabilities. Article 50 of the RAIF Law explicitly enshrines this segregation, protecting investors in one compartment from risks in another.
This structuring flexibility allows the SICAV-RAIF to serve as a platform for diverse investment strategies. For example, a single SICAV-RAIF may house private equity, real estate, and debt compartments, each targeting different investor groups or geographies. Meanwhile, asset managers can tailor investment policies, fee structures, and leverage levels at the compartment level. Notably, each SICAV-RAIF compartment can issue its own classes of shares, supporting tailored investor rights and economics.
Additionally, umbrella fund structuring reduces operational duplication. The SICAV-RAIF can centralise administration, custody, and reporting for all compartments, achieving cost efficiencies. Managers commonly use this feature when launching successive vintages, feeder funds, or dedicated mandates within the same platform.
For private equity and real estate, the SICAV-RAIF compartments can mirror deal-by-deal or sector-specific strategies. For this reason, family offices and institutional investors often select the SICAV-RAIF umbrella fund format to optimise governance and reporting across multiple portfolios.
SICAV-RAIF tax treatment and subscription tax
The SICAV-RAIF benefits from a favourable Luxembourg tax regime. The fund itself qualifies as a fully tax-exempt entity for most direct taxes. The SICAV-RAIF does not pay corporate income tax, municipal business tax, or net wealth tax on its investment activities. Instead, it pays an annual subscription tax (taxe d’abonnement) of 0.01% of net asset value, calculated quarterly. This rate applies to typical SICAV-RAIF strategies, including private equity and real estate. Certain compartments, such as those investing solely in other Luxembourg funds, may benefit from further exemptions.
Luxembourg’s extensive tax treaty network does not cover the SICAV-RAIF directly. Nevertheless, the structure often achieves tax neutrality at the fund level, with investors taxed according to their own jurisdictional rules. Additionally, the SICAV-RAIF can access VAT exemptions for most fund management services, reducing operational costs.
For carried interest and management fees, the Luxembourg tax regime offers competitive tax treatment to fund managers and key personnel. The AIFM can structure fee arrangements efficiently within the SICAV-RAIF model, subject to transfer pricing and substance requirements.
Asset managers should conduct a detailed tax review at the compartment level, as investor jurisdictions and asset types may influence optimal structuring.
Establishing a SICAV-RAIF platform in Luxembourg
Incorporation and legal process
The formation of a SICAV-RAIF involves several key steps. Promoters must first draft and notarise the constitutional documents, including articles of association and the offering memorandum. The SICAV-RAIF must appoint an authorised AIFM, which may be located in Luxembourg or another EU Member State. The AIFM assumes responsibility for portfolio management, risk management, and regulatory oversight under the AIFMD.
In turn, the SICAV-RAIF appoints a Luxembourg depositary, central administrator, and auditor. These service providers must meet regulatory standards and ensure operational integrity. The fund must file its incorporation with the Luxembourg Trade and Companies Register (RCS). Within fifteen days of launch, the RAIF must notify the CSSF via submission of the constitutive documents and AIFM appointment details, as required by the RAIF Law.
Ongoing governance and compliance
Although the CSSF does not supervise the SICAV-RAIF directly, the appointed AIFM ensures ongoing compliance with AIFMD requirements. The AIFM manages risk controls, portfolio valuation, and reporting to both investors and regulators. The SICAV-RAIF must maintain its registered office and legal seat in Luxembourg, and must comply with anti-money laundering (AML) and counter-terrorism financing (CTF) rules.
SICAV-RAIF platforms support a wide range of investment strategies. Managers can structure open-ended or closed-ended compartments, each with tailored subscription and redemption terms. Notably, the RAIF regime places no restrictions on eligible asset classes, supporting sophisticated and innovative strategies.
Asset managers should focus on substance, governance, and investor transparency when establishing a SICAV-RAIF. Adequate local presence, board composition, and operational infrastructure are essential for long-term success.
For guidance on structuring a variable capital RAIF or launching a SICAV-RAIF real estate or private equity platform, fund sponsors should consult experienced Luxembourg advisors. The right structuring approach can deliver significant efficiency and investor appeal.
