Luxembourg Soparfi structures provide tax-efficient holding company benefits but require €12,000+ minimum capital and strict substance requirements. 67% of applications fail due to insufficient economic substance documentation.
What Is Soparfi
Soparfi (Société de Participations Financières) means financial participation company. Not a legal form, it's a tax designation for Luxembourg companies holding shares in other companies.
Common legal forms: SARL (€12,000 capital), SA (€30,000 capital), SàRL-S (simplified SARL, €1 capital but limited scope).
Tax Advantages
Participation exemption: 0% tax on dividends received from qualifying subsidiaries. 0% tax on capital gains from sale of qualifying participations.
Qualifying participation: At least 10% shareholding OR €1.2 million acquisition cost OR held for 12+ months uninterrupted.
Withholding tax exemption: 0% WHT on dividends paid to parent company if EU Parent-Subsidiary Directive applies or tax treaty covers.
Luxembourg has 80+ double tax treaties. Strategic Soparfi placement eliminates withholding taxes on cross-border dividend and royalty flows.
Substance Requirements
Must demonstrate real economic activity in Luxembourg. Required: Luxembourg registered office (can't be mailbox), at least 1 Luxembourg resident director, local bookkeeping and accounting.
Board meetings in Luxembourg (minimum 1 per year documented). Strategic decisions made in Luxembourg (documented in minutes). Bank account with Luxembourg bank.
EU blacklist risk: Pure letterbox companies without substance face tax treaty benefit denial. Luxembourg tax authorities audit 15% of new Soparfi structures annually.
Formation Costs
Notary fees: €1,500-2,500 for deed of incorporation. RCS registration: €100. Publication in Mémorial: €50-100.

Capital Requirements
SARL Soparfi: €12,000 minimum, fully paid at incorporation. SA Soparfi: €30,000 minimum, 25% paid upfront (€7,500), rest within 5 years.
Capital must be cash or assets. Cannot use services or future commitments. Deposit in Luxembourg bank in blocked account until incorporation complete.
Payment Trap
Bank account opening takes 4-8 weeks BEFORE you can deposit capital. Notary won't finalize incorporation without proof of capital deposit.

Must end with legal form: "SARL", "SA", or full text "Société à Responsabilité Limitée" / "Société Anonyme".
Cannot use: "Luxembourg", "National", "Royal", "Government" without authorization. Banking/finance terms require CSSF license (financial regulator).
Director Requirements
SARL: At least 1 manager (gérant), can be foreign national. SA: At least 3 directors, majority must be Luxembourg or EU residents for substance.
Nominee director services available: €3,000-8,000/year. Director assumes legal liability - choose reputable firm only.
Foreign Directors
Non-EU directors need Schengen visa for Luxembourg visits. No residence permit required if not living in Luxembourg permanently.
But substance rules require decision-making in Luxembourg. Minimum 4 board meetings per year physically in Luxembourg recommended to satisfy tax authorities.
Don't use Soparfi if you can't visit Luxembourg 4+ times per year. Tax authorities audit travel records to verify substance claims.

Real estate holding: Exemption on sale of shares (vs direct property sale taxed at 6-10%). Pre-sale restructuring: Transfer assets to Soparfi before exit for capital gains exemption.
