SICAR Luxembourg Investissement: A Comprehensive Legal and Tax Guide
The SICAR (Société d’Investissement en Capital à Risque) is a cornerstone of Luxembourg’s investment fund toolbox, specifically designed for risk capital investments. Governed by the law of 15 June 2004, this regulated vehicle offers a unique combination of operational flexibility and a highly attractive tax regime, making it a preferred choice for private equity, venture capital, and mezzanine debt strategies. As a leading Luxembourg law firm, Lerusse Merckx & Partners provides expert guidance on structuring, launching, and managing SICARs to maximize investor returns while ensuring full regulatory compliance.
Unlike traditional investment funds, the SICAR is not subject to risk-spreading requirements, allowing it to concentrate on a limited number of portfolio companies. This feature, coupled with a full exemption on income and capital gains from qualifying investments, positions the SICAR as a powerful tool for targeted private equity and venture capital projects. In this guide, we explore the legal framework, tax advantages, setup process, and strategic considerations for using a SICAR in your Luxembourg investment structure.
What is a SICAR? Legal Framework and Key Characteristics
The SICAR (Société d’Investissement en Capital à Risque) is a Luxembourg investment vehicle specifically created for risk capital investments. Introduced by the law of 15 June 2004, it is designed to hold and manage participations in entities that represent a risk capital exposure. Unlike UCITS or other regulated funds, a SICAR is not required to diversify its portfolio, allowing it to focus on a small number of target companies. This makes it particularly suitable for private equity, venture capital, and mezzanine financing strategies.
A SICAR can be structured as a public limited company (SA), a private limited company (Sàrl), a partnership limited by shares (SCA), or a cooperative in the form of a public limited company. It must be authorized by the CSSF (Commission de Surveillance du Secteur Financier) and is subject to ongoing supervision. The vehicle is intended for well-informed investors who understand the risks associated with risk capital investments. The minimum investment per investor is typically EUR 30,000, ensuring that only qualified or institutional investors participate.
The SICAR regime is distinct from other Luxembourg vehicles like the SOPARFI or the RAIF. While a SOPARFI is a fully taxable holding company benefiting from participation exemption, a SICAR enjoys a near-total tax exemption on income and gains from its qualifying investments. This makes it a highly efficient vehicle for private equity structures. For a detailed comparison, see our guide on SOPARFI Luxembourg: The Ultimate Holding Company Guide 2026.
Eligible Assets and Investment Policy
The SICAR must invest exclusively in ‘risk capital’ assets, defined as direct or indirect investments in entities that are not listed on a regulated market. This includes equity, quasi-equity instruments, and mezzanine debt. The law explicitly excludes investments in listed securities, real estate (unless held through a risk capital entity), and pure debt instruments. However, a SICAR may hold ancillary liquid assets for cash management purposes.
The investment policy must be clearly defined in the SICAR’s articles of incorporation and offering documents. While there is no legal requirement for diversification, the CSSF will review the policy to ensure it aligns with the risk capital objective. The SICAR can invest in a single target company, making it ideal for acquisition vehicles or project-specific structures. For real estate investments, a specialized fund structure may be more appropriate; see our Real Estate Investment in Luxembourg guide.
Tax Regime of the SICAR: A Competitive Advantage
The SICAR benefits from a highly favorable tax regime that is central to its appeal. It is fully exempt from corporate income tax, municipal business tax, and net wealth tax on income and capital gains derived from qualifying risk capital investments. This exemption extends to dividends, interest, and capital gains from the sale of participations. However, income from non-qualifying assets (e.g., bank interest) is taxed at the standard corporate rate of 24.94% (including the solidarity surcharge) in Luxembourg City for 2025.
Instead of income tax, the SICAR is subject to an annual subscription tax (taxe d’abonnement) of 0.01% on its net assets, calculated and payable quarterly. This tax is capped, meaning that for large SICARs, the effective tax burden is minimal. There is no withholding tax on dividends distributed by the SICAR, nor on interest payments, making it highly efficient for international investors. Capital gains realized by non-resident investors on the sale of SICAR shares are generally not taxable in Luxembourg, provided the investor does not hold a substantial participation (typically less than 10%) and has not been a Luxembourg resident for more than six months.
The SICAR also benefits from Luxembourg’s extensive double tax treaty network and the EU Parent-Subsidiary Directive, which can eliminate withholding taxes on inbound dividends. However, careful structuring is required to ensure that the SICAR itself qualifies for treaty benefits.

Subscription Tax and VAT Considerations
The subscription tax of 0.01% is levied on the net assets of the SICAR, as valued in accordance with Luxembourg accounting principles. For SICARs that invest primarily in other funds, the tax may be reduced or eliminated if those underlying funds are already subject to subscription tax. Additionally, management services provided to a SICAR are generally exempt from VAT, which is a significant cost advantage compared to ordinary commercial companies.
It is important to note that the SICAR is not subject to the EU Anti-Tax Avoidance Directives (ATAD) interest limitation rules, as it is not considered a corporate taxpayer for income tax purposes. This provides further flexibility in financing structures. However, the SICAR must comply with Luxembourg transfer pricing rules for transactions with related parties, ensuring arm’s length conditions.
Regulatory Framework and CSSF Supervision
The SICAR is a regulated investment vehicle under the supervision of the CSSF. Before commencing activities, it must obtain authorization from the CSSF, which involves submitting a detailed application including the articles of incorporation, investment policy, risk management procedures, and information on the directors and managers. The CSSF reviews the application to ensure compliance with the law of 15 June 2004 and related regulations. The approval process typically takes between 3 and 6 months, depending on the complexity of the structure.
Once authorized, the SICAR must comply with ongoing regulatory obligations, including annual audited financial statements, semi-annual reports, and notification of any material changes to the CSSF. The SICAR must appoint a Luxembourg-based depositary (for assets that are financial instruments) or a custodian, as well as an independent auditor. The directors and managers must be of good repute and possess adequate professional experience. For SICARs that qualify as alternative investment funds (AIFs) under the AIFMD, an authorized alternative investment fund manager (AIFM) must be appointed. Learn more about AIFM requirements in our AIFM Luxembourg Agrément CSSF: A Complete Guide.
The minimum capital requirement for a SICAR is EUR 1 million, which must be reached within 12 months of authorization. The SICAR can be set up as a single fund or as an umbrella structure with multiple sub-funds, each with a distinct investment policy. This flexibility allows for efficient segregation of assets and liabilities between sub-funds, a feature particularly useful for multi-strategy private equity platforms.
AIFMD Implications and Passporting
Most SICARs fall within the scope of the Alternative Investment Fund Managers Directive (AIFMD) as they are considered alternative investment funds (AIFs). This means the SICAR must appoint a fully authorized AIFM or, if eligible, a registered AIFM under the lighter regime. The AIFM is responsible for portfolio management and risk management, and must comply with the directive’s requirements on remuneration, liquidity, and reporting. The SICAR itself benefits from the AIFMD marketing passport, allowing its shares to be marketed to professional investors across the EU.
For smaller managers, Luxembourg offers a lighter registration regime for AIFMs managing portfolios below certain thresholds (EUR 100 million for unleveraged AIFs or EUR 500 million for leveraged AIFs with no redemption rights for five years). In such cases, the SICAR can be managed by a registered AIFM, which is subject to reduced regulatory obligations. Our firm can advise on the optimal AIFMD structure for your SICAR.
SICAR vs. Other Luxembourg Investment Vehicles
Choosing the right vehicle is critical. The SICAR is often compared to the SOPARFI and the RAIF. A SOPARFI is an ordinary taxable company that benefits from the participation exemption regime, making it suitable for holding activities but not for collective investment schemes. It is not regulated by the CSSF and does not benefit from the SICAR’s tax exemption on income. However, a SOPARFI can be used for a wider range of assets, including real estate and intellectual property. For a detailed comparison, see our SOPARFI Luxembourg guide.
The RAIF (Reserved Alternative Investment Fund) is a more recent vehicle that combines features of the SIF and SICAR but without direct CSSF product supervision. It must be managed by an authorized AIFM, which provides indirect regulatory oversight. The RAIF offers greater flexibility in terms of eligible assets and can be used for a broader range of strategies, including real estate and hedge funds. However, the SICAR’s specific tax exemption for risk capital investments remains unique. For more on RAIFs, read our RAIF Luxembourg: The Flexible Alternative Investment Fund Vehicle.
The SIF (Specialized Investment Fund) is another regulated vehicle but requires risk diversification and is subject to a higher subscription tax (0.01% on net assets, but with a minimum of EUR 1,250 per year). The SICAR’s lack of diversification requirement and its targeted tax exemption make it the preferred choice for concentrated private equity portfolios. Ultimately, the choice depends on the investment strategy, investor base, and tax considerations. Our team at Lerusse Merckx & Partners can help you navigate these options.
Setting Up a SICAR: Step-by-Step Process
The establishment of a SICAR involves several key steps. First, the structure must be designed: choice of legal form (SA, Sàrl, SCA), drafting of the articles of incorporation, and preparation of the offering document (prospectus) if shares are to be publicly placed. The prospectus must contain detailed information on the investment policy, risk factors, and the rights of investors. Next, the application is submitted to the CSSF, along with supporting documents such as the CVs of directors, business plan, and proof of minimum capital.
Upon CSSF approval, the SICAR is incorporated before a Luxembourg notary and registered with the Trade and Companies Register (RCS). The entire process, from initial filing to authorization, typically takes 3 to 6 months, assuming all documentation is complete and no significant issues arise. The costs include CSSF filing fees (EUR 5,000 for a single fund, EUR 10,000 for an umbrella structure), notary fees, legal fees, and ongoing service provider costs. Our firm offers fixed-fee packages for SICAR incorporation to provide cost certainty.
Post-authorization, the SICAR must appoint a depositary or custodian, an auditor, and, if required, an AIFM. Ongoing compliance includes annual audits, CSSF reporting, and adherence to anti-money laundering (AML) regulations. The SICAR must also register for VAT and obtain a Luxembourg tax number. With proper planning, the setup can be streamlined. For a broader overview of company formation, see our Luxembourg Company Formation & Registration Guide.
Timeline and Practical Considerations
A realistic timeline for a standard SICAR setup is as follows: preparation of documentation (4-6 weeks), CSSF review (8-12 weeks), incorporation and post-authorization steps (2-4 weeks). Delays can occur if the investment policy is complex or if the CSSF requests additional information. Engaging experienced legal counsel early can significantly expedite the process. Lerusse Merckx & Partners has a proven track record of securing CSSF approvals efficiently.
It is also essential to consider the substance requirements. The SICAR must have a central administration in Luxembourg, meaning key decisions are made there. This typically requires at least one Luxembourg-resident director and a physical office. Our firm can provide domiciliation and directorship services to meet these requirements.
