Investment Funds in Luxembourg: RAIF, SIF, SICAR - Comparison
Alternative investment funds in Luxembourg are mainly structured around three vehicles: the RAIF (launch in 2 to 4 weeks, without direct CSSF supervision), the SIF (CSSF authorisation in 4 to 8 weeks, strong regulatory label), and the SICAR (venture capital and private equity, full IRC exemption). Luxembourg is the world's second-largest asset management centre with more than €5 trillion under management.
RAIF - Reserved Alternative Investment Fund
The RAIF (Reserved Alternative Investment Fund) was introduced in 2016. It is not directly supervised by the CSSF, but must be managed by an authorised Alternative Investment Fund Manager (AIFM). It is the fastest solution to implement (no direct authorisation of the fund required).
- No direct CSSF supervision (very short launch time: 2-4 weeks)
- Mandatorily managed by an authorised AIFM
- Reserved for well-informed investors (minimum €125,000 investment)
- Can take the form of an SCSp, SARL, SA, or SCA
SIF - Specialised Investment Fund
The SIF (Specialised Investment Fund) is directly supervised by the CSSF. It is suitable for managers wishing to display a strong regulatory label to institutional investors. Its authorisation time is around 4 to 8 weeks.
SICAR - Investment Company in Risk Capital
The SICAR is dedicated to venture capital and private equity. It must invest exclusively in securities representing risk capital. It benefits from a full exemption from IRC (corporate income tax) and VAT on its income linked to eligible investments.
