Private equity structuring in Luxembourg: the deal SOPARFI, from acquisition to exit.
A Luxembourg private equity structure rests on two tiers: a vehicle that pools capital, often an SCSp or a RAIF, and a holding company, the deal SOPARFI, that owns the investments. This page covers the second tier: what it adds, what it must evidence, what it costs each year and what makes it fail. Financial Services Luxembourg works on accounting, substance and reporting; CSSF authorisation and reserved acts are coordinated with our network of partner lawyers and notaries.

Private equity structuring in Luxembourg places the investments in one or more holding SOPARFIs, resident and fully taxable, below a fundraising vehicle, a transparent SCSp or a RAIF. The holding gets treaty access and the article 166 LIR participation exemption, subject to thresholds, holding period and subsidiary eligibility.
Participation exemption: article 166 LIR. SCSp: law of 12 July 2013. RAIF: law of 23 July 2016, with an authorised alternative investment fund manager. Checked on 30 October 2026: thresholds, holding period and eligible subsidiary (guichet.lu), waiver (Administration des contributions directes, law and grand-ducal regulation of 20 December 2024), minimum net wealth tax (Administration des contributions directes).
Key takeaway
- Typical scheme: fund (SCSp or RAIF), then deal SOPARFI, then investments.
- The SOPARFI gets treaty access and the article 166 LIR exemption, subject to thresholds, holding period and subsidiary eligibility.
- Substance is evidenced by facts kept in a file reviewed every year: resident management, board meetings held in Luxembourg, accounting records kept on site.

Why insert a SOPARFI below the fund?
The SOPARFI performs three functions the fundraising vehicle cannot: access to the Luxembourg double tax treaty network, exemption of qualifying dividends and capital gains under article 166 LIR, and a financing layer that ring-fences each investment at acquisition and at exit.
What are the conditions of the article 166 LIR exemption?
The holding exempts dividends and capital gains with 10% of the subsidiary’s capital, or an acquisition price of EUR 1,200,000 or EUR 6,000,000, held for 12 uninterrupted months.
| Condition | Dividends and liquidation proceeds | Capital gains on disposal |
|---|---|---|
| Percentage threshold | 10% of the subsidiary’s capital | 10% of the subsidiary’s capital |
| Alternative acquisition price | EUR 1,200,000 | EUR 6,000,000 |
| Holding period | 12 uninterrupted months, or a commitment to hold | Same |
| Eligible subsidiary | Fully taxable capital company, entity covered by the parent-subsidiary directive, or non-resident company subject to a tax comparable to corporate income tax | Same |
| Basis | Article 166 LIR | Article 166 LIR and grand-ducal regulation of 21 December 2001 |
Can you waive the article 166 LIR exemption?
Yes, from tax year 2025, but only where the exemption rests on the acquisition price threshold. The waiver is requested for each tax year and each investment. It results from the law and the grand-ducal regulation of 20 December 2024; whether to use it is a matter for the group’s tax adviser.
What does each tier of a private equity structure do?
The fundraising vehicle pools investor commitments; the deal SOPARFI owns, funds and sells the investments. Only the second has treaty access, which is the technical reason for the holding tier.
| Question | Fund tier (SCSp or RAIF) | Holding tier (deal SOPARFI) |
|---|---|---|
| Function | Pool and manage investor commitments | Own, finance and sell the investments |
| Tax status | Transparent for the SCSp | Resident and fully taxable |
| Tax treaties | No access | Access |
| Article 166 LIR exemption | Not applicable | Applicable under conditions |
| Usual form | SCSp, RAIF | Most often an SARL, SA possible |
| Investment decisions | Manager, GP or AIFM | SOPARFI bodies, documented locally |
| Accounting | See fund accounting | LuxGAAP bookkeeping, annual accounts, returns |
What counts as sufficient substance for a deal SOPARFI?
SOPARFI substance is evidenced by six verifiable facts, gathered in a file kept current and reviewed every year.
- A board of managers mostly resident in Luxembourg and qualified.
- Board meetings held in Luxembourg, with minutes signed on site.
- Bank accounts whose signing powers are exercised locally.
- Accounting records and corporate archives kept at the registered office.
- Own means proportionate to the holding activity.
- Material decisions taken by the Luxembourg bodies.
What forfeits the exemption or weakens a substance file?
An ineligible subsidiary or an unmet holding period forfeits the exemption. A substance file weakens through accumulation: no single indicator recharacterises the company, but together they can.
- Minutes dated in Luxembourg but signed from abroad.
- A management body reduced to one non-resident individual.
- Bank instructions issued from the sponsor’s headquarters.
- No transfer pricing file on intragroup loans.
- A domiciliation with no own means.
- Investment decisions documented at fund level, never at SOPARFI level.
How much does the holding tier cost each year?
Only the minimum net wealth tax is set by law: EUR 535, EUR 1,605 or EUR 4,815 by balance sheet total. Bookkeeping, domiciliation, management and transfer pricing are quoted.
| Item | Basis | Amount or rule |
|---|---|---|
| Minimum net wealth tax, balance sheet up to EUR 350,000 | Balance sheet total | EUR 535 |
| Minimum net wealth tax, balance sheet EUR 350,000 to 2,000,000 | Balance sheet total | EUR 1,605 |
| Minimum net wealth tax, balance sheet above EUR 2,000,000 | Balance sheet total | EUR 4,815 |
| Reduction of the minimum tax | Corporate income tax and employment fund contribution due | Deducted from the minimum |
| Bookkeeping, annual accounts, RCS filing | Volume of entries and number of entities | On quotation |
| Domiciliation and management | Level of substance required | On quotation |
| Transfer pricing file on intragroup loans | Number and amounts of loans | On quotation |
| Audit of the accounts | Legal thresholds and statutory choices | Case by case |
How is carried interest taxed since 2026?
Since 1 January 2026, purely contractual carried interest is taxed at one quarter of the beneficiary’s global rate, at most 11.45% before the 1.4% dependency insurance contribution. In the accounts, it appears as an allocation of profit following the order of priority in the partnership agreement.
What happens at exit?
An exit triggers four workstreams in parallel, run on the timetable that the buyer sets.
- Accounts of the selling company brought up to date, interim statements for the data room.
- Testing of the article 166 LIR conditions on the gain.
- Handling of expenses deducted in earlier years.
- Moving the proceeds up to the fundraising vehicle.
How many SOPARFIs does a structure need?
It depends on the number of target jurisdictions and on whether each disposal should be ring-fenced. One SOPARFI per investment makes a share sale cleaner and separates risks. A single platform lowers the fixed annual cost but blends holding histories, which complicates the recapture of expenses at exit.
The fixed cost repeats for each SOPARFI: it is the trade-off between one company per investment and a single platform. The firm’s fees are on the pricing page, and a firm quote is issued within 48 hours. The general holding framework is described on the SOPARFI page, the choice between RAIF, SIF and SICAR in the comparison of fund vehicles.
Why are expenses on an exempt participation the most underestimated point?
The point most often underestimated is not the threshold but its reverse: expenses directly linked to an exempt investment are deductible only to the extent they exceed the exempt income of that investment for the year. A per-investment analytical record is kept from acquisition, not at the time of sale.
Recapture of previously deducted expenses is the item that most often surprises at exit, because it is computed over the full holding history and not over the year of disposal. The thresholds and scales in force are published on the tax parameters page.
The so-called shell directive, ATAD 3, has been withdrawn. Several publications still present it as forthcoming.
Who does what in the structure?
The notary receives the incorporation deeds. Lawyers and tax advisers issue the opinions on the structure. The manager, GP or AIFM, takes the investment decisions. Where the vehicle triggers them, the authorised manager, the depositary and the approved statutory auditor are separate professionals.
Financial Services Luxembourg keeps the accounts of the companies across both tiers and prepares the financial statements and the reporting inputs set out in the partnership agreement. Domiciliation is provided with an avocat à la Cour (List I). Management mandates are exercised in our own name under business licence 10077275, with no nominee mandates (see directorship services). Striking the net asset value and the registrar function rest with the authorised professional appointed for that purpose. See also fund accounting and the SCSp.

Frequently asked questions
Why a SOPARFI under the fund?
The SCSp is transparent and has no treaty access. The SOPARFI, resident and fully taxable, does, benefits from the article 166 LIR exemption and eases financing and exit.
Which vehicle to raise capital?
Most often a transparent SCSp or a RAIF managed by an authorised manager, depending on the investor base and strategy. The choice between vehicles is covered in the RAIF, SIF and SICAR comparison.
Can a SOPARFI waive the article 166 LIR exemption?
Yes, from tax year 2025, only where the exemption rests on the acquisition price threshold. It is requested for each tax year and each investment, and whether to use it is a matter for tax advice.
What is the annual minimum tax of a SOPARFI?
Since 2025 it depends only on the balance sheet total: EUR 535 up to EUR 350,000, EUR 1,605 up to EUR 2,000,000, EUR 4,815 above. It is reduced by the corporate income tax due.
How is carried interest treated in the accounts?
It is recorded as an allocation of profit following the order of priority set in the partnership agreement. The firm keeps the vehicle’s accounts and prepares the allocation statements; the manager settles the final split.
Do you do legal due diligence?
We perform financial due diligence and coordinate legal due diligence with partner lawyers.
