Running a Soparfi in Luxembourg.

What a Soparfi is

A Soparfi, short for société de participations financières, is an ordinary Luxembourg company whose main job is to own shares in other companies.

It is not a special legal form and it has no regime of its own. Most Soparfis are set up as an SARL or an SA, and they pay the same corporate taxes as any other Luxembourg company. They are popular because three standard rules work together in their favour:

• the participation exemption, which can exempt dividends and gains from the companies the Soparfi owns;
• access to the EU Parent-Subsidiary Directive and Luxembourg's tax treaties, because the Soparfi is a normal taxpayer;
• an exemption from withholding tax on dividends paid to qualifying company shareholders.

Entrepreneurs use one to hold their operating company, so dividends and sale proceeds can be reinvested without being taxed in their own hands first. Families use one to keep participations together and organise the next generation. International groups use one to hold European subsidiaries.

SARL or SA?

Both are created before a notary and registered with the Luxembourg Business Register. If you are unsure, our legal structure finder walks you through the choice.

Money coming in

The participation exemption is why most Soparfis exist. Dividends, liquidation proceeds and capital gains from the companies it owns can be completely exempt, as long as the company it owns qualifies and the Soparfi holds enough of it for long enough.

The company you own qualifies if it is covered by the EU Parent-Subsidiary Directive, is a fully taxable Luxembourg company, or is based abroad and pays a tax comparable to Luxembourg corporate tax. The 12 months can also be met by committing to keep the shares for that long.

The fine print

• Costs linked to the shares are clawed back. If the Soparfi borrowed to buy a participation, that interest is not deductible in a year when it receives an exempt dividend, up to the dividend amount. When it sells, the gain is taxed to the extent of costs and write-downs deducted in earlier years.
• Artificial arrangements do not qualify. Dividends the paying company could deduct, or that come from set-ups whose main purpose is to obtain a tax advantage, are not exempt.
• You can opt out in one case. Since 2025, where a holding only qualifies through the €1.2 million cost test, the Soparfi can choose each year not to apply the exemption to it.

What the holding pays

A Soparfi pays corporate tax on whatever is not exempt, such as interest it earns, management fees it charges, or gains on shares that do not qualify.

Net wealth tax, the one most holdings actually pay

Every company pays net wealth tax of 0.5% of its net assets each year, falling to 0.05% above €500 million. Shares that meet the 10% or €1.2 million test are exempt, with no minimum holding period. Once those are left out, there is usually little left to tax, so most Soparfis pay the minimum net wealth tax, set since 2025 by the size of the balance sheet:

Other rules worth knowing

• Interest on borrowings is deductible up to €3 million, or 30% of tax EBITDA if higher. Few private holdings come near that.
• Loans between group companies need a written agreement and an arm's length interest rate, with documentation to back it up.
• The global minimum tax (Pillar Two) only concerns groups with revenue of €750 million or more.

Money going out

When the Soparfi pays a dividend, Luxembourg normally withholds 15%, which a tax treaty can reduce. No withholding tax applies when the shareholder is a qualifying company (an EU company, a Luxembourg company, or a comparable company in a treaty or EEA country) that holds at least 10%, or shares that cost €1.2 million, for 12 months.

A few things leave the Soparfi without any withholding tax at all: liquidation proceeds, ordinary interest on loans, and royalties. Interest that depends on profits, or that is above market rate, is the exception.

Where withholding tax applies, the return and payment are due within eight days of the dividend being made available. When you plan a distribution, we prepare the shareholders' resolution, check whether an exemption applies and file what is needed.

VAT

A holding that only owns shares and receives dividends is generally not a VAT taxpayer and does not register. That changes when it starts doing more, for example invoicing management fees to its companies, letting property, or buying services from abroad. It may then need a VAT number, to charge 17% VAT or self-assess it, and to file returns. It is worth checking before the first invoice goes out. We handle VAT registration and returns when you need them.

Your year

A Soparfi with five transactions a year has the same deadlines as a busy trading company. For a financial year ending on 31 December, it looks like this:

1. 10 FebruaryAdvance payment of municipal business tax and net wealth tax, then again on 10 May, 10 August and 10 November.
2. 10 MarchAdvance payment of corporate income tax, then again on 10 June, 10 September and 10 December.
3. By 30 JuneThe shareholders approve last year's accounts at the annual general meeting.
4. By 31 JulyThe accounts are validated on eCDF and filed with the Luxembourg Business Register.
5. By 31 DecemberCorporate income tax, municipal business tax and net wealth tax returns for last year are filed.

On top of that, the register of beneficial owners (RBE) has to be updated whenever ownership changes, and the shareholder register and minutes kept at the registered office. Late advance payments cost 0.6% interest per month. Our free compliance calendar shows the deadlines for every type of company.

Office and substance

A registered office

Every Luxembourg company needs a registered office here. Most holdings do not rent premises, so they use a domiciliation agent instead. Under the law of 31 May 1999 this is a regulated activity: the agent signs a domiciliation agreement with the company, checks who owns it, and keeps its corporate records at the address.

We arrange domiciliation and mail handling through our licensed partner, and pass on their fees without any markup. When you sign up, the agent will ask for identity documents for the shareholders, managers and beneficial owners. We gather these with you so the process does not drag.

Being run from Luxembourg

Tax authorities, in Luxembourg and abroad, increasingly check that a holding is really managed from here. A Soparfi without enough substance can lose its treaty benefits or the dividend exemptions. In practice, that means taking the important decisions in Luxembourg at properly minuted meetings, having managers with real authority who live here (especially for companies that lend within a group), and keeping the books and records here. If you need a Luxembourg-resident director, our partner can provide one.

Setting one up

1. Decide the structure. What the Soparfi will own, who its shareholders are, and how it is financed. If you need structuring advice, we bring in an independent lawyer.
2. Arrange the registered office through our partner, or use your own premises.
3. Pay in the capital. Cash goes into a Luxembourg bank account, and the bank issues the certificate the notary needs. Contributions in kind need a valuation report.
4. Sign before the notary. The notary incorporates the company and files the deed with the Business Register.
5. Declare the beneficial owners in the RBE, and register with the tax authorities, including for VAT if needed.
6. Start the books from day one, with your figures available in myFinbros.

We coordinate every step with the notary, the bank and our partner. Incorporation is €1,250.

Pitfalls we see

• Selling before 12 months. The gain can become fully taxable.
• Forgetting the minimum net wealth tax in a year with no income.
• Filing the accounts late, which happens most often with dormant holdings.
• Lending money without paperwork: no loan agreement, no interest rate. It is one of the first things a tax inspector asks about.
• Charging management fees to subsidiaries without checking VAT first.
• Leaving the RBE out of date after a change of shareholders.

What we do, and prices
