Concept
SOPARFI (société de participations financières) is an ordinary Luxembourg company designed for holding equity stakes; there is no separate legal form behind this designation. Luxembourg does not make it an offshore: SOPARFI is a fully taxable resident with a combined rate of approximately 23.87%. The entire point lies in participation: income from it is exempt from tax.
Participation Exemption under Art. 166
If a SOPARFI holds at least 10% of the capital of a subsidiary company—or a stake with an acquisition price of at least €1.2 million—and holds it for at least 12 months, then dividends, capital gains, and liquidation proceeds from that stake are exempt from tax. This is the same principle as the Dutch BV, only with a 10% threshold instead of 5% or a monetary criterion. From 2025, an opt-out option has been introduced when the exemption applies only by the value criterion—flexibility for structures where the ordinary regime is more advantageous.
Rates and Withholdings
As of January 1, 2025, Luxembourg reduced the corporate income tax (CIT) from 17% to 16%; with municipal business tax and the employment fund contribution, the combined rate for the capital is 23.87%. Outgoing dividends are subject to a 15% withholding tax by default, but are reduced to zero under the participation exemption or the Parent-Subsidiary Directive within the EU. Interest and liquidation proceeds are generally not subject to withholding tax.
Why Choose Luxembourg
Luxembourg is infrastructure: deep expertise, a network of more than 80 tax treaties, reputation with banks and funds, direct access to EU directives. That is why SOPARFI often becomes the top of the structure for private equity, funds, and family holdings that value not only the exemption but also predictability and acceptance by counterparties worldwide.
Substance and Pillar Two
As everywhere in the EU, formal registration is not enough. A SOPARFI must have a real presence—directors, office, decision-making in Luxembourg—otherwise tax treaties and directives may not apply. ATAD, anti-hybrid rules, and—from 2024—Pillar Two with a minimum effective rate of 15% for large groups are in force. This has shifted the choice from "where the rate is lower" to "where there is substance and sustainability."
💡 SOPARFI is a fully taxable company (23.87%), but income from participations is exempt under Art. 166: threshold of 10% capital or €1.2 million with a 12-month holding period. The value lies in the network of tax treaties, access to EU directives, and reputation, while the rate itself remains ordinary.
