The Luxembourg RAIF to structure your investment internationally
The Luxembourg Reserved Alternative Investment Fund (RAIF) offers a flexible investment platform for professional and institutional investors. The RAIF regime, introduced by the Law of 23 July 2016, allows sponsors to set up alternative investment funds without direct authorisation or ongoing supervision by the CSSF. Instead, an authorised Alternative Investment Fund Manager (AIFM) must manage the RAIF. This approach streamlines time-to-market and reduces regulatory friction compared to traditional regimes.
Specifically, the RAIF allows investment strategies across private equity, real estate, debt, infrastructure, and other alternative asset classes. Fund promoters use the RAIF for its structuring flexibility and pan-European marketing passport under the AIFMD. Meanwhile, the legal framework supports a broad range of legal forms, including the SCA, S.à r.l., S.A., SCS, and SCSp. As a result, sponsors can tailor the RAIF to match investor requirements and underlying strategies. The RAIF regime remains suitable for closed-ended, open-ended, and hybrid funds.
Unlike SIFs or SICARs, the CSSF does not approve or supervise the RAIF directly. Instead, the AIFM ensures regulatory compliance and risk management. The absence of direct regulatory approval enables rapid fund launches—often within weeks. Nevertheless, the RAIF remains a regulated product under the Law of 23 July 2016 and AIFMD.

RAIF vs SIF: Key Regulatory and Structural Differences
Regulatory Supervision and Approval
The SIF (Specialised Investment Fund) and RAIF both target well-informed investors. However, the CSSF directly authorises and supervises each SIF. By contrast, the RAIF regime relies on the AIFM for regulatory oversight. Therefore, the SIF involves a lengthier authorisation process, while the RAIF achieves faster time-to-market. Fund managers seeking speed and pan-European marketing often select the RAIF.
AIFM Requirement and Investor Protection
The Law of 23 July 2016 mandates that an authorised AIFM manages every RAIF. The AIFM ensures risk management, compliance, and reporting to regulators. In contrast, a SIF may appoint an AIFM but can, in some circumstances, be self-managed. The mandatory AIFM requirement for RAIFs guarantees a consistent regulatory standard. This structure protects investors by aligning with the AIFMD framework.
Eligible Assets and Strategies
Both RAIFs and SIFs permit broad investment policies, including real estate, private equity, debt, and infrastructure. However, the RAIF can also elect the risk capital regime, enabling private equity strategies under SICAR-like rules. Sponsors often prefer the RAIF for hybrid or multi-asset strategies due to its flexibility. In turn, the SIF may appeal to managers seeking direct CSSF supervision for specific investor mandates.
RAIF Compartments and SIF Sub-Funds
Both structures support umbrella funds with segregated compartments. Nevertheless, the RAIF’s legal framework—especially Article 50 of the Law of 23 July 2016—ensures statutory ring-fencing of assets and liabilities between compartments. This protection offers significant comfort for institutional investors operating multi-strategy platforms.
RAIF Tax Regime and Subscription Tax
General Taxation of RAIFs
Luxembourg RAIFs do not pay corporate income tax, municipal business tax, or wealth tax on fund-level income. Instead, the regime imposes an annual subscription tax (taxe d’abonnement) at 0.01% of net asset value. The law exempts certain assets—such as investments in other Luxembourg funds or money market instruments—from this levy. Therefore, the RAIF provides a tax-efficient platform for institutional and cross-border investors.
RAIFs structured as SCSp, SCS, or S.à r.l. with full tax transparency may further optimise tax outcomes. Specifically, the RAIF can access double tax treaties and implement efficient withholding tax planning when structured with appropriate legal and operational substance. The reserved alternative investment fund remains a preferred vehicle for real estate, private equity, and debt strategies seeking to minimise tax leakage.
RAIF Risk Capital Regime
The Law of 23 July 2016 allows RAIFs to opt for the risk capital regime. In this scenario, the regime aligns taxation with SICAR rules. The RAIF then invests primarily in risk capital (private equity and venture capital). The fund becomes exempt from the subscription tax but must meet specific portfolio eligibility criteria. This option offers further tax optimisation for private equity fund sponsors.
VAT and Withholding Tax Considerations
Luxembourg RAIFs qualify as VAT-exempt for fund management services under Article 44.1.d of the Luxembourg VAT Law. Additionally, the law exempts RAIFs from withholding tax on distributions to non-resident investors. These features enhance the RAIF’s cross-border appeal for global institutional capital.
Compartment Structuring Under the RAIF Framework
Umbrella Structure and Segregation
RAIFs can operate as umbrella funds with multiple compartments. Each compartment pursues a separate investment policy and can target distinct investor bases. Article 50 of the Law of 23 July 2016 enshrines statutory segregation. Therefore, assets and liabilities of each compartment remain strictly separated. Creditors of one compartment cannot claim against another compartment’s assets.
This legal ring-fencing provides operational clarity and reduces cross-liability risk for investors. It also allows managers to launch new strategies or asset classes under a single fund umbrella. For example, a RAIF may combine a real estate fund, a private equity fund, and a debt fund within separate compartments. Each compartment can have its own currency, fee structure, and service providers.
Practical Structuring Insights
Managers often use the compartment regime to scale their Luxembourg operations efficiently. For instance, they can add new compartments over time without setting up separate legal entities. Each compartment can accommodate specific investor requirements—such as different subscription periods, redemption policies, or performance fee structures. This flexibility supports institutional portfolio diversification and streamlines operational management.
Furthermore, the legal segregation simplifies exit transactions. Managers can sell or spin off a compartment independently, with no impact on the remaining compartments. This structure appeals to sponsors developing multi-strategy platforms or targeting diverse investor segments.
RAIF Formation: Requirements, Timeline, and AIFM Appointment
Eligible Investors and Minimum Capital
The RAIF regime restricts access to well-informed investors. These include institutional investors, professional investors under MiFID II, and other investors subscribing at least EUR 125,000. The minimum RAIF capital is EUR 1,250,000. The fund must reach this threshold within twelve months of launch.
Legal Forms and Incorporation
Sponsors can incorporate a RAIF using several legal forms, such as SCA, S.à r.l., S.A., SCS, or SCSp. The selection depends on the target investor base, fund strategy, and tax considerations. For example, the SCSp structure remains popular for private equity and real estate funds due to its contractual flexibility and tax transparency. The Law of 23 July 2016 governs the RAIF regime, while the Law of 10 August 1915 applies to the underlying company law aspects.
RAIF Fund Formation Process
The sponsor drafts a constitutive document—such as a limited partnership agreement or articles of incorporation. In parallel, the AIFM finalises the fund’s offering documentation and compliance framework. The RAIF does not require CSSF authorisation. Therefore, the fund can launch immediately upon notarial incorporation and AIFM appointment. In most scenarios, the formation process takes two to four weeks, subject to completion of AML/KYC checks and operational set-up.
RAIF AIFM Requirement and Service Providers
The Law of 23 July 2016 requires every RAIF to appoint an authorised AIFM. The AIFM assumes responsibility for portfolio and risk management, in addition to regulatory reporting. The AIFM’s authorisation enables the RAIF to benefit from the pan-EU AIFMD marketing passport. Sponsors must also appoint a Luxembourg depositary, central administrator, and auditor. These service providers ensure compliance with local regulations and investor protection standards.
Furthermore, the AIFM manages reporting to the CSSF and other European regulators under the AIFMD framework. This structure reduces operational risk and assures institutional investors of strong governance. The AIFM’s experience with alternative asset classes—such as real estate, private equity, and debt—adds significant value for fund sponsors.
Key Considerations for Fund Managers
- Define the investment policy and eligible asset classes clearly in the offering documents.
- Select the legal form and compartment structure to match investor and strategy needs.
- Engage a reputable AIFM with proven expertise in the relevant asset classes.
- Ensure operational readiness, including AML/KYC, risk management, and reporting systems.
- Plan for ongoing governance and compliance obligations under AIFMD and the Law of 23 July 2016.
