Set up an investment fund in Luxembourg
Fund regimes, capital, budgets and service providers: plan the key decisions for your project.
To set up an investment fund in Luxembourg, identify the investors and strategy, select the regime and legal form, then arrange the management and required service providers. The financing plan distinguishes set-up fees, annual costs and the capital needed for investment.
This guide is primarily for promoters of alternative funds and co-investment vehicles. Financial Services Luxembourg may undertake accounting work for eligible companies associated with the project and coordinate exchanges with appropriately authorised professionals. The engagement is defined after reviewing the entities and the work requested.
Securitisation operates under a regime distinct from investment funds: review securitisation and its accounting implications.
Choose the regime and legal form
RAIF, SIF and SICAR are fund regimes. The special limited partnership (SCSp) is a legal form. A RAIF can therefore be established as an SCSp. The manager is a third component of the project.
| Decision | Question to resolve | Key points |
|---|---|---|
| Fund regime | Which rules apply to investors, assets and supervision? | RAIF, SIF, SICAR or another framework to be determined |
| Legal form | How should contributions, investor rights and governance be organised? | SCSp, SA, Sàrl or a common fund (FCP), depending on the regime |
| Manager | Who is responsible for managing the fund and meeting the associated obligations? | An alternative investment fund manager is known as an AIFM in English or a GFIA in French. Its regulatory status depends on the vehicle and applicable framework. |
In principle, a RAIF (reserved alternative investment fund) requires an external authorised AIFM. The fund itself does not require prior product authorisation from the Commission de surveillance du secteur financier (CSSF).
A SIF, or specialised investment fund, and a SICAR, an investment company in risk capital, require CSSF authorisation. Their management obligations also depend on their classification and the applicable framework.
Before choosing a structure, specify the target assets, investor profiles, countries in which the fund will be marketed, any use of borrowing and the exit arrangements.
Whether a vehicle qualifies as an alternative investment fund (AIF) must be assessed by reference to how the project actually operates. An SCSp is not automatically an AIF; the absence of authorisation for the vehicle does not remove the need to assess the manager’s status.

Distinguish fund capital from subscription amounts
The vehicle’s statutory minimum, each investor’s commitment and service providers’ fees are three separate amounts. A regulatory threshold of €1.25 million is not a set-up fee.
| Regime | Statutory minimum | Deadline for reaching the minimum |
|---|---|---|
| RAIF | €1,250,000 | 24 months after formation; for an FCP, after the management regulations take effect |
| SIF | €1,250,000 | 24 months after authorisation |
| SICAR | €1,000,000 | 24 months after authorisation |
What the minimum measures depends on the legal form: net assets for a common fund; subscribed capital plus premiums, or the value of partnership interests, for the company and partnership forms covered by the legislation. The timetable for paying in contributions must be checked separately.
The SCSp legal form has no minimum capital of its own. If it operates under a fund regime that imposes a minimum, that regime’s requirements apply.

Investor eligibility requirements
RAIFs, SIFs and SICARs are reserved for well-informed investors. This category includes institutional and professional investors. Other investors must confirm their status in writing and either invest at least €100,000 or obtain the assessment required by law from an eligible professional.
Statutory exceptions apply in particular to directors and other persons involved in managing the vehicle.
The fund may set a higher contractual minimum investment. Subscription commitments and capital calls must therefore be read together with the vehicle’s rules.

Plan the steps and timeline
Legal formation and the start of operations are two different milestones. Launching the fund depends on documentation, identity and source-of-funds checks, acceptance by service providers and the required authorisations.
The preparation process can be organised into six steps:
- Describe the project. Define the strategy, assets, investors, target amount and countries involved.
- Determine the structure’s legal and regulatory status. Establish the regime, legal form, manager’s status and marketing rules.
- Select the providers. Define responsibilities, establish their acceptance requirements and obtain quotations.
- Prepare the documents. Set out investor rights, governance, subscriptions and service agreements.
- Complete the formalities. Establish the vehicle, complete registrations and obtain the necessary authorisations.
- Prepare for operations. Organise cash flows, accounting, valuation, controls and reporting deadlines.
A RAIF avoids prior CSSF product authorisation. Its manager and service providers still need to be appointed. For a SIF or SICAR, CSSF authorisation forms part of the timetable.
A practical timetable specifies the document required, the responsible party and the condition for moving to the next stage at each step. A formation date alone does not guarantee the date of the first transaction.

Build the full budget
A fund’s budget includes set-up fees, recurring expenses and transaction-related costs. The providers needed and their fees depend on the regime, assets, investors and chosen operating structure.
| Category | Items to review in quotations |
|---|---|
| Set-up | Legal advice, documentation, formation, registrations and provider onboarding |
| Annual operations | Manager, administration, depositary and auditor where required, accounting for the relevant companies and reporting obligations |
| Variable fees | Costs relating to transactions, compartments, unit classes, investors, valuations or changes to documentation |
Ask each provider to specify the calculation basis, annual minimum, included services, exclusions and VAT treatment in its quotation. Check for overlapping services across packages before adding up the amounts.
Measure the impact of fees
Consider a hypothetical annual budget of €50,000, for illustration:
| Reference asset value | Hypothetical annual budget as a percentage of assets |
|---|---|
| €2,000,000 | 2.5% |
| €10,000,000 | 0.5% |
Calculation: annual budget divided by the reference asset value. Set-up fees are excluded from this example. The €50,000 figure is an assumption used for the calculation, not an estimate of Financial Services’ fees or market rates.
This calculation helps assess the effect of expenses on the project. It should then be repeated using the quotations received, the assets expected at launch and the actual fee arrangements.
Allocate responsibilities
The fund’s functions and the accounting for its related companies must be assigned explicitly. The table lists the functions to consider. The structure determines which are mandatory and which entities may perform them.
| Provider or function | Role to define in the engagement |
|---|---|
| Fund manager | Portfolio and risk management under the applicable framework |
| Administration of an undertaking for collective investment (UCI) | Functions including registrar services and accounting with net asset value calculation |
| Depositary | Safekeeping or asset verification duties, cash flow monitoring and statutory oversight duties |
| Approved statutory auditor | Audit of the accounts where required |
| Legal and tax advisers | Documentation and analysis of matters within their engagement |
| Accountant for eligible companies | Bookkeeping, reconciliations, closing work and agreed information for entities within the accountant’s permitted scope |
Net asset value (NAV) is the value of assets less liabilities. The value per unit is derived from it according to the classes and the fund’s rules. Responsibilities and contracts must distinguish the production of accounting data from the regulated NAV calculation function.

Review the tax treatment
Tax treatment depends on the fund regime, legal form and investors’ circumstances. The taxation of the vehicle must be distinguished from the taxation of distributions received by each investor.
SIFs and RAIFs under the standard regime benefit from direct tax exemptions and are, in principle, subject to an annual subscription tax of 0.01% of net assets, with possible exemptions.
RAIFs under the Article 48 risk-capital regime and SICARs follow different rules. For fiscally opaque forms, these include taxation with specific exemptions, which must be assessed according to the income concerned.
An SCSp is in principle transparent for corporate income tax purposes. The reverse-hybrid rules and, where relevant, municipal business tax must also be considered.

Prepare your engagement with Financial Services
Financial Services Luxembourg supports the accounting needs of eligible entities and coordinates exchanges with the appointed professionals. The engagement is defined after reviewing the companies concerned, the work requested and the requirements governing the profession.
The work may cover the accounts of the GP, meaning the general partner, the sponsor’s companies and SPVs, meaning companies dedicated to holding assets, where those entities are eligible.
Depending on the engagement letter, the firm may provide:
- Bookkeeping and reconciliations.
- Closing work and the agreed financial statements.
- Preparation of information for the other parties involved.
- Coordination of communications and deadlines within its engagement.
UCI administration and official NAV calculation remain with appropriately authorised entities. Licensed accountant status does not constitute authorisation to perform every function of a fund.

Frequently asked questions
Do I have to choose between a RAIF and an SCSp?
These terms describe two different aspects of the structure. A RAIF is a fund regime; an SCSp is a legal form. A single vehicle can be an SCSp subject to the RAIF regime. The choice therefore concerns how they are combined and the resulting obligations.
Can I launch a fund without being an authorised manager myself?
A sponsor can appoint a separate manager. In principle, a RAIF requires an external authorised AIFM. For other projects, the manager’s status depends on the vehicle’s classification and the applicable framework. Establishing the vehicle does not, by itself, confer the right to perform fund management.
Is an SCSp without product authorisation exempt from regulation?
The SCSp legal form does not provide a general exemption. Its possible classification as an alternative investment fund, the manager’s status and the obligations arising from its activities must be assessed. The assessment concerns how the structure actually operates.
