SPF as LP in an Unregulated SCSp: Combining Family Wealth Management and Investment

1 day ago

6 min read

Families that manage their financial wealth through a Luxembourg SPF increasingly want exposure to private markets such as private equity, venture capital and co-investments. A common answer is to hold the investment as a limited partner in an unregulated SCSp, a combination that joins the SPF's light tax regime with the SCSp's flexibility and transparency.

The structure in brief

The family owns a Luxembourg SPF, which subscribes as a limited partner to an unregulated SCSp. The SCSp is managed by a general partner (GP), usually a Luxembourg company, and invests in the underlying assets. Other investors can join as limited partners, and the SCSp can be a fund run by an independent sponsor or a vehicle sponsored by the family itself.

Why combine an SPF with an SCSp

Private market access with light taxation: The SPF is exempt from corporate income tax, municipal business tax and net wealth tax, and pays only an annual subscription tax.
Predictable cost: The subscription tax is based on the SPF's paid-up capital and share premium, plus any debt above eight times that amount, not on the value of the SCSp interest or on uncalled commitments.
No extra tax layer: The SCSp is generally tax transparent in Luxembourg, so it adds no corporate income tax or net wealth tax of its own.
Flexibility: The SCSp has no minimum capital and the limited partnership agreement can be tailored to capital calls, distributions and governance.
Family organisation: Several family members can hold a single SPF, which in turn holds the private investments, which simplifies governance and succession.

Key conditions for the SPF

Eligible shareholders: The SPF must be held by eligible persons, such as individuals managing their private wealth, estate planning vehicles acting for them and intermediary vehicles.
Eligible assets: The SPF may hold only financial assets and cash. The SCSp interest must qualify as an eligible asset under the SPF law, which should be confirmed in each case.
Passive role: The SPF must not be involved in the management of the SCSp or of its investments. This matches the position of a limited partner, which should not act as manager towards third parties.
No commercial activity or direct real estate: The SCSp's strategy should be reviewed, particularly for real estate or operating business investments.
No GP role: The SPF should not act as general partner, since that implies management and unlimited liability. The GP should be a separate company.

A breach of the SPF conditions can mean losing the special regime and falling under ordinary corporate taxation, so the SCSp's terms and the family's role should be checked before the commitment is made.

Taxation at a glance

At SPF level: The SPF is exempt from corporate income tax, municipal business tax and net wealth tax. It pays an annual subscription tax of 0.25% on its paid-up capital, share premium and any debt above eight times that amount, with a minimum of EUR 1,000 and a maximum of EUR 125,000. Distributions to shareholders are generally not subject to Luxembourg withholding tax.

At SCSp level: The SCSp is tax transparent for corporate income tax and net wealth tax, pays no subscription tax and makes distributions free of Luxembourg withholding tax. It can become subject to municipal business tax only if it carries out a business activity or if its general partner is a capital company holding 5% or more of its interests.

Foreign taxes: The SCSp has no treaty access of its own, and the SPF generally cannot rely on Luxembourg's double tax treaties or the EU Parent-Subsidiary Directive. Foreign withholding tax on dividends and interest may therefore not be recoverable unless a SOPARFI blocker or a Cyprus or Singapore company are held by the SCSp, and the holding chain of the underlying investments should be reviewed.

At family level: Each family member is taxed in their country of residence on distributions from the SPF.

Illustrative examples

The figures below are simplified, assume the SPF and SCSp conditions are met, and are for illustration only.

Example 1: Subscription tax follows paid-up capital, not commitments

The family commits EUR 20 million to the SCSp through its SPF. Uncalled commitments are not part of the subscription tax base. When EUR 10 million has been called, funding it entirely with equity would mean a tax of 0.25% of EUR 10 million, or EUR 25,000. If the SPF instead funds the calls with EUR 2 million of share capital and share premium and an EUR 8 million documented shareholder loan, the debt is four times the equity, below the eight times threshold, so the tax is 0.25% of EUR 2 million, or EUR 5,000. Once the full EUR 20 million has been called, EUR 2.25 million of equity and EUR 17.75 million of loan keep the debt below eight times equity (EUR 18 million), for a tax of EUR 5,625 instead of EUR 50,000. Debt above eight times equity would be added to the base, and the interest may be taxable for the lender in their country of residence.

Example 2: Gains and distributions

The SCSp sells a portfolio company and realises a EUR 12 million gain. The SPF holds 25% of the interests, so its share is EUR 3 million. There is no Luxembourg tax at SCSp or SPF level on it, and a distribution to the family carries no Luxembourg withholding tax. Each family member is then taxed in their own country of residence.

Example 4: Foreign withholding tax

A foreign portfolio company pays a EUR 2 million dividend to the SCSp. The SPF's 25% share is EUR 500,000, and the source country withholds tax at an assumed 15%, or EUR 75,000. Because neither the SCSp nor the SPF generally has treaty access, this amount may not be recoverable, which is why the holding chain matters. If a SOPARFI or a Cyprus or Singapore company is held by the SCSp the source witholding tax subject to the treaty jurisdiction may be mitigated or recovered.

Example 5: The GP's 5% threshold

Partners commit EUR 100 million in total, of which the GP holds EUR 1 million (1%). As the GP's interest is below 5%, the SCSp is not deemed to carry on a business. If the GP held EUR 6 million (6%), a EUR 10 million profit would bear municipal business tax of about EUR 675,000 at the 6.75% Luxembourg City rate.

Setting up in five steps

Check eligibility: confirm the shareholders, the SPF's activities and whether the SCSp interest is an eligible asset.
Review the SCSp: limited partnership agreement, investment policy, GP structure and stake (below 5%), manager or AIFM status, and the rights of limited partners.
Set up or adapt the SPF: articles with the SPF corporate object, and a funding plan that balances equity and shareholder loans against the expected capital calls.
Subscribe and register: sign the subscription documents, update the SCSp's partner register and update beneficial ownership registrations.
Monitor the structure: track capital calls, the subscription tax base and the SPF's continuing eligibility each year.

Staying compliant

The SPF must keep to its eligible shareholders, assets and passive role at all times, file its annual accounts, pay its subscription tax each quarter and keep its beneficial ownership data up to date. It should also monitor the SCSp's strategy and any changes to the GP, the manager or the limited partnership agreement. The SCSp and its GP have their own accounting, RCS, RBE and AML obligations, and where the SCSp is an AIF its AIFM carries out valuation, risk management and reporting duties.

Is this structure right for you?

The combination suits families with a substantial financial portfolio who want to add private equity, venture capital or co-investments in a passive, tax-efficient way, either through an independent sponsor's SCSp or a family-sponsored vehicle. If you plan to hold operating companies, take an active role in management, own real estate directly or need treaty access, a SOPARFI or another vehicle may be a better fit.
