# Luxembourg SOPARFI: Classic Holding with Participation Exemption > How a Luxembourg SOPARFI holding works: dividend and capital gains exemption under Art. 166, combined rate of 23.87% from 2025, and requirements for stake and substance.

It is an ordinary Luxembourg company under general company law (the 1915 Commercial Companies Act) used to hold participations. It is a fully taxable resident with a combined rate of about 23.87% and carries no offshore status. Its efficiency comes from participation: income from qualifying shareholdings is lifted out of the tax base under a dedicated regime. ## Where the SOPARFI came from Before the SOPARFI, Luxembourg's calling card was the 1929 holding regime (H29): the law of 31 July 1929 gave holding companies almost complete tax exemption. The EU treated that regime as prohibited state aid — it was closed to new companies from 2007, and existing ones were allowed to run until the end of 2010. The replacement had been prepared in advance: in 1990 Luxembourg transposed the Parent-Subsidiary Directive into national law, and the SOPARFI took over from H29. It is an ordinary taxable company that obtains its exemption through participation; it has no special status, and that is precisely what made Luxembourg resilient to EU state-aid challenges. ## Participation exemption under Art. 166 If a SOPARFI holds a stake for at least 12 months, income from it is exempt from tax. For dividends and liquidation proceeds the threshold is 10% of the subsidiary's capital or an acquisition price of at least €1.2 million; for capital gains on a disposal it is the same 10% or, alternatively, €6 million. This is the same principle as the [Dutch BV](https://wiki.private.law/en/company-netherlands), only with a 10% floor instead of 5%. Since 2025 it has been possible to opt out of the exemption for stakes that qualify on the price test alone (€1.2 million or €6 million) — annually and stake by stake; this eases interaction with Pillar Two. ## Rates and withholdings From 2025 Luxembourg cut corporate income tax (IRC) from 17% to 16%; together with the 7% employment-fund surcharge and municipal business tax, the combined rate for the capital is 23.87% — unchanged in 2026. Outbound dividends are subject to 15% withholding tax by default, but this drops to zero under the participation exemption or the EU Parent-Subsidiary Directive; interest and liquidation proceeds are generally free of withholding tax. On top of this a SOPARFI pays an annual net wealth tax — 0.5% of net assets and 0.05% on the amount above €500 million, with a minimum of between €535 and €4,815 depending on the size of the balance sheet. ## SOPARFI or SPF Alongside the SOPARFI sits the SPF (société de gestion de patrimoine familial) — a passive vehicle for the private wealth of individuals. An SPF is exempt from corporate tax and pays only a 0.25% taxe d'abonnement, but in return it is restricted: passive holding of financial assets only, no commercial activity, no direct real estate, and no access to tax treaties or EU directives. The SPF suits a quiet family portfolio; the SOPARFI is chosen where you need the treaty network, inbound and outbound flows and operational flexibility. ## Why choose Luxembourg Luxembourg is infrastructure: deep expertise, a network of more than 80 tax treaties, a reputation with banks and funds, and direct access to EU directives. On this combination it competes with the [Netherlands](https://wiki.private.law/en/company-netherlands), [Cyprus](https://wiki.private.law/en/company-cyprus) and [Ireland](https://wiki.private.law/en/company-ireland), and the SOPARFI often becomes the top of a [holding structure](https://wiki.private.law/en/holding-structures) for private equity, [funds](https://wiki.private.law/en/funds) and family holdings — where what matters is not only the exemption but also predictability and acceptance by counterparties worldwide. ## Where it is used In practice a SOPARFI most often sits at the head of investment structures. Private-equity and real-estate funds gather European assets under it — frequently paired with a RAIF, SICAR or [SCSp](https://wiki.private.law/en/scsp-luxembourg), where the SOPARFI holds the stakes while the fund wrapper raises capital from investors. The largest managers — Blackstone, KKR and Brookfield — have run through Luxembourg holdings for decades: they are drawn by the treaty network and the predictability of administration. Family offices use a SOPARFI as a single point of ownership for assets across different jurisdictions — it makes reporting, succession planning and restructuring easier. ## Substance and Pillar Two As everywhere in the EU, formal registration is not enough. A SOPARFI must have a real presence — directors, an office, decisions taken in Luxembourg — or tax treaties and directives may not apply; this is [economic substance](https://wiki.private.law/en/economic-substance). [ATAD and CFC rules](https://wiki.private.law/en/eu-atad-cfc) apply, along with anti-hybrid measures and, since 2024, Pillar Two with its 15% minimum effective rate for groups with turnover of €750 million or more. The choice has shifted from "where is the rate lowest" to "where is there substance and durability". > ⚙️ Minimum working substance: a majority of directors are Luxembourg residents, meetings and key decisions take place locally, there is an office, a separate account and local accounting. Without this, treaties and directives risk not applying, and deductions risk being challenged. ## What changed by 2026 The main news is what did not happen. On 18 June 2025 ECOFIN formally withdrew the ATAD 3 (Unshell) directive from the agenda: member states could not agree on common criteria for "empty" companies, and there will be no dedicated anti-shell regime in the EU. Part of its logic is proposed for transfer into the DAC6 reform under discussion for 2026. It is too early to relax: substance requirements have not gone anywhere — they continue to operate through GAAR, the principal purpose test and the conditions for applying the directives. Pillar Two, meanwhile, has moved from statute into routine: Luxembourg has launched registration and filing for the minimum tax, and in summer 2025 tabled draft law no. 8591 in parliament — it transposes DAC9 (automatic exchange of GloBE information returns) and refines the QDMTT mechanics, including reallocating top-up tax from securitisation companies to other companies in the group. For groups with turnover of €750 million or more, the participation-exemption opt-out (see above) has become a working lever for managing the effective rate. Rates are stable: IRC of 16% and the combined 23.87% for the capital were unchanged in 2026, and the treaty network has grown to 88 agreements in force. ## What to watch Transparency has its price. A SOPARFI's beneficial owners are entered in Luxembourg's UBO register, and cross-border arrangements bearing the marks of aggressive planning are disclosed under DAC6 (hallmark). Post-BEPS tax treaties contain a principal purpose test: if a structure has no business purpose beyond a tax benefit, the relief is refused. Preparing a SOPARFI therefore involves more than registration — it needs real [substance](https://wiki.private.law/en/economic-substance), [confirmed beneficial ownership](https://wiki.private.law/en/beneficial-ownership-nominee), a clear business rationale and a readiness to report under the [disclosure rules](https://wiki.private.law/en/dac6-hallmarks) and pass the [principal purpose test](https://wiki.private.law/en/gaar-ppt). After the tightening of substance rules, ATAD and Pillar Two, the SOPARFI remains a working tool: a predictable environment has been built around it — treaties, directives, banks and market habit. That is why it holds its place where simply cutting the rate no longer solves the problem. ## How it works in practice 1. **Scope.** We define the task: the top of a holding, an acquisition vehicle for a deal, a consolidation point for family assets — and honestly check whether a SOPARFI is needed at all or the task can be solved more simply (an SPF, an [SPV](https://wiki.private.law/en/spv) in another jurisdiction). 2. **Structure.** The form (S.à r.l. or SA), place in the ownership chain, a check of the participation-exemption thresholds, dividend flows and substance requirements; for group turnover of €750 million or more — a calculation of the Pillar Two position. 3. **Incorporation.** Articles before a notary, capital contribution, registration with the RCS, entry of beneficial owners in the RBE register, tax registrations. 4. **Bank and launch.** Opening an account, appointing resident directors, a calendar of meetings and reporting — the minimum substance on which the reliefs rest. Timeline: depends on the form, the notary and the bank's KYC — we give a realistic plan after scoping. Cost: we quote the range after a short scoping call.

Income from qualifying participations is lifted out of the base — that is the whole point of the construction. ### **When are dividends and capital gains exempt?** With a 12-month holding: for dividends — at least 10% of the subsidiary's capital or an acquisition price of €1.2 million; for capital gains — the same 10% or €6 million. Since 2025 an annual opt-out is available for stakes qualifying on the price test alone — useful for groups inside Pillar Two. ### **How is a SOPARFI different from an SPF?** The SPF is a passive box for private wealth: no corporate tax, but also no treaty access, no EU directives, no commercial activity and no direct real estate; it pays a 0.25% taxe d'abonnement. A SOPARFI is a full tax resident with the treaty network and operational flexibility. ### **Does Pillar Two apply to a SOPARFI?** Only if it belongs to a group with consolidated revenue of at least €750 million — then the 15% minimum effective rate and the Luxembourg QDMTT apply. Family structures and smaller fund stacks usually stay outside Pillar Two, but the group perimeter is worth checking early. ### **What happened to ATAD 3 (Unshell)?** ECOFIN formally withdrew the proposal on 18 June 2025 — there will be no dedicated EU shell-company regime. Substance is still policed through GAAR, treaty principal-purpose tests and directive conditions, and part of the Unshell logic may resurface in a DAC6 reform. ### **What minimum substance does a holding need?** A majority of Luxembourg-resident directors, board meetings and key decisions taken locally, an office, a local account and accounting, and decision-making capacity proportionate to the assets. A letterbox with a nominee director is exactly what ATAD and principal-purpose tests are built to catch. > 🔗 **Related** > [Luxembourg route](https://wiki.private.law/en/luxembourg) · [holding structures](https://wiki.private.law/en/holding-structures) · [Dutch holding (BV)](https://wiki.private.law/en/company-netherlands) · [Cyprus holding](https://wiki.private.law/en/company-cyprus) · [SPV](https://wiki.private.law/en/spv) · [funds](https://wiki.private.law/en/funds) · [economic substance](https://wiki.private.law/en/economic-substance) · [the five-flag theory](https://wiki.private.law/en/five-flags) · [ATAD and CFC](https://wiki.private.law/en/eu-atad-cfc) · [Holding ladder and dividend flows](https://wiki.private.law/en/holding-dividend-flows) · [Luxembourg funds: UCITS, SIF and RAIF](https://wiki.private.law/en/luxembourg-sif-raif) · [SCSp](https://wiki.private.law/en/scsp-luxembourg) · [Irish holding](https://wiki.private.law/en/company-ireland) · [Swiss holding](https://wiki.private.law/en/company-switzerland) > 💡 A SOPARFI is a fully taxable company (about 23.87%), but income from participations is exempt: for dividends the threshold is 10% of capital or €1.2 million, for capital gains 10% or €6 million, with a holding period of at least 12 months.
