Luxembourg / Holding company
And that is exactly why it works. A Luxembourg S.à r.l. or S.A. whose activity is holding participations falls inside Article 166 — fully taxable, therefore treaty-resident, therefore able to use the network the old exempt vehicles could not.
Current for 2026. A further one-point cut to the corporate rate has been announced for 2027, which would bring the aggregate to roughly 22.8%.
Until 2010 Luxembourg had a dedicated exempt holding vehicle, the Holding 1929. It paid almost no tax — and because it paid almost no tax, it was not a resident for treaty purposes and could not use Luxembourg's treaty network at all.
In July 2006 the European Commission found the regime to be existing State aid incompatible with the common market. Because it was existing rather than unlawful aid, nothing was recovered: Luxembourg abolished it by the end of 2006, with grandfathering for companies already in it until 31 December 2010.
The SOPARFI is the deliberate opposite. It is an ordinary taxpayer that happens to hold shares. The exemption is not granted to the company — it is granted to specific streams of income that meet specific conditions. That is the whole design, and it is why the structure still works.
23.87% is an aggregate nominal rate. A working SOPARFI's effective rate is usually far lower, because its principal income is exempt rather than taxed.
The minimum net wealth tax is determined solely by total balance sheet. The former test based on balance-sheet composition — financial assets above 90% of the total — was struck down by the Constitutional Court and no longer applies.
Article 166 exempts qualifying dividends and capital gains from corporate income tax and municipal business tax. It is conditional, and the conditions differ between the two.
The cost test is an alternative, not an addition. A 4% stake acquired for EUR 5 million qualifies for dividend exemption on cost, even though it fails the 10% test.
“Comparable tax” has a number attached. A non-resident subsidiary must be fully liable to a tax corresponding to Luxembourg corporate income tax at a minimum rate of at least 8% — half the 16% rate — on a comparably determined base. Below that line the exemption falls away on income that was assumed to be clean.
Recapture applies to gains. Expenses and write-downs previously deducted in relation to the participation reduce the exempt amount on disposal. Groups that financed an acquisition through the SOPARFI and deducted interest along the way routinely find the exit less exempt than modelled.
A SOPARFI rarely stands alone. Where a Dutch B.V. also appears, the two are not redundant: Luxembourg is the investment and exit layer, the Netherlands the operational one.
Duplicating both functions in one entity works until an exit, a joint-venture partner or a lender needs them separated — at which point restructuring costs more than building it correctly would have. Luxembourg vs Netherlands →
The exemption, treaty rates and directive benefits are all conditional on the company having a genuine function. After ATAD I and II and the Principal Purpose Test delivered through the Multilateral Instrument, a SOPARFI that exists only to receive income and pass it on is exposed on every one of them at once.
In practice: Luxembourg-resident directors with real authority, board meetings held and minuted in Luxembourg, a registered office that is not solely a mailbox, bank mandates exercised locally, and decisions actually taken where the company is said to be managed. Substance is cheapest when designed in from incorporation and most expensive when retrofitted under audit. What is actually tested →
No. It is a fully taxable Luxembourg company subject to the ordinary 23.87% aggregate rate in Luxembourg City. Specific income streams — qualifying dividends and capital gains — are exempt under Article 166 LIR. Full taxability is what gives it treaty access.
10% of the subsidiary's share capital, held or committed to be held for twelve months. Alternatively an acquisition cost of EUR 1.2 million for dividends, or EUR 6 million for capital gains, satisfies the test regardless of percentage.
The S.à r.l. is used in the large majority of holding structures: EUR 12,000 minimum capital, a private shareholder register and restricted transfers. The S.A. — EUR 30,000, a wider shareholder base, a supervisory framework — is chosen where the shareholding is broad or the entity may be listed or syndicated.
There is no statutory residence requirement. But tax residence and treaty access depend on where the company is effectively managed, and a board with no Luxembourg-resident members exercising genuine authority is hard to defend. Our own practice is to build boards with a Luxembourg-resident majority — a risk judgement, not a legal rule.
Yes. The exemption extends to subsidiaries subject to a tax comparable to Luxembourg corporate income tax — from 2025, a minimum rate of at least 8% on a comparably determined base. The test is substantive and should be run per subsidiary rather than assumed for the group.
No. The autorisation d'établissement is required for commercial, craft and most professional activities. A company whose activity is holding participations does not carry one — which is one of the practical differences between a SOPARFI and an operating company.
