panoramica
Jurisdiction overview
Luxembourg is the EU's second-largest investment fund centre globally (after the United States) and the leading cross-border fund domicile within the European Economic Area. The jurisdiction combines political stability, multilingual talent (French, German, English, Luxembourgish), and a legal framework rooted in Napoleonic civil law with Anglo-Saxon fund pragmatism. The Luxembourg company register (RCS) is digitised, searchable, and integrates seamlessly with EU directives on beneficial ownership (UBO register) and anti-money laundering (4AMLD/5AMLD/6AMLD transposition).
For company registration Luxembourg, physical presence is non-negotiable. The Grand Duchy's tax authorities (Administration des Contributions Directes, ACD) and financial regulator (Commission de Surveillance du Secteur Financier, CSSF) require genuine economic substance: a registered office with lease agreement, at least one Luxembourg-resident director (or a licensed corporate director), audited accounts, and documented board meetings on Luxembourg soil. Remote or nominee-only structures trigger automatic CFC or permanent-establishment attribution in founder home jurisdictions.
The luxembourg company formation cost reflects this substance requirement. A standard private limited company (S.à r.l.) entails notarial fees (circa €1,500–€2,000), registration duty (€75 fixed), legal drafting (€2,000–€3,000), and first-year domiciliation/directorship (€2,000–€4,000). Regulated vehicles—RAIF, SIF, SICAV—add CSSF filing fees (€4,000–€7,000), compliance documentation, and depositary/audit appointments, pushing aggregate cost to €30,000–€80,000. The luxembourg trade and companies register publishes annual accounts for S.A. and large S.à r.l., ensuring transparency but also scrutiny by home-country tax authorities under CRS/DAC6/BEPS Action 13 (CbCR).
Luxembourg's 86 double-tax treaties and full participation in the EU Parent–Subsidiary and Interest & Royalties directives afford powerful withholding-tax optimisation. However, OECD BEPS Pillar Two (global minimum tax 15%) and EU ATAD anti-hybrid provisions constrain aggressive planning. US founders must file Form 5471 (and potentially Form 8621 PFIC) annually; UK founders post-Finance Act 2025 face tightened CFC rules where Luxembourg profits are attributed unless genuine CIGA and local decision-making are evidenced.
tipologie societarie
Available company types
1. S.à r.l. (Société à responsabilité limitée)
The workhorse private limited company for holdings, IP licensing, and service entities. Minimum capital: €12,000 (must be paid at incorporation). One or more shareholders (natural or corporate), at least one manager (need not be resident, but substance requires local director or professional service). S.à r.l. is not subject to mandatory audit below certain thresholds (balance sheet <€4.4m, turnover <€8.8m, employees <50). Luxembourg company formation for S.à r.l. takes three weeks; notarial deed is compulsory, and the RCS registration triggers the 17% VAT registration unless exempt financial activity. US founders: if the S.à r.l. is a disregarded entity (single-member LLC analogue), check-the-box election may cause flow-through taxation, avoiding Subpart F but not GILTI inclusion.
2. S.A. (Société Anonyme)
Public limited company; popular for regulated funds and listing-ready structures. Minimum capital: €30,000 (€1,200,000 if offering securities to the public). Requires board of directors (minimum three), statutory auditor, and annual AGM. The S.A. must publish audited accounts in the luxembourg company register, heightening transparency. Company registration luxembourg as S.A. suits institutional investors requiring governance frameworks aligned with AIFMD or UCITS. Setup cost: €10,000–€15,000 (legal + notarial + registration duty).
3. SOPARFI (Société de Participations Financières)
Not a separate legal form but a tax label for holding companies (structured as S.à r.l. or S.A.) eligible for participation exemption: 0% tax on dividends and capital gains from qualifying subsidiaries (≥10% shareholding, ≥€1.2m acquisition price or 10% equity, 12-month holding). No withholding tax on outbound dividends to EU parents or treaty-country shareholders. SOPARFIs underpin multi-tier structures but require substance: ACD audits nexus rigorously under BEPS Action 5 (harmful tax practices). Register company Luxembourg as SOPARFI costs €8,000–€12,000, including tax ruling application (6–8 weeks).
4. RAIF (Reserved Alternative Investment Fund)
Unregulated AIF (no CSSF product authorisation) under 2016 RAIF law; requires an authorised external AIFM (EU or third-country with passport). Minimum capital: none prescribed; typical subscription €1m+. RAIF formation: 4–6 weeks; cost €25,000–€40,000. Ideal for private equity, real estate, debt funds targeting professional/institutional investors. Still subject to AML/KYC, depositary, and audit requirements.
5. SCSp (Société en Commandite Spéciale)
Special limited partnership: tax-transparent in Luxembourg (no entity-level tax), limited partners enjoy liability cap, general partner bears unlimited liability. SCSp is AIFMD-compliant, often wrapped with RAIF or SIF umbrella. Luxembourg fund formation via SCSp appeals to US tax-exempt investors (avoiding UBTI) and UK pension schemes. Setup: €15,000–€30,000; timeline: 3–5 weeks.
6. SIF (Specialised Investment Fund)
Regulated AIF for well-informed investors; minimum subscription €125,000. CSSF authorisation required (8–12 weeks). Cost: €40,000–€80,000. SIF offers broader eligible-asset flexibility than UCITS but narrower than RAIF.
tassazione
Taxation and tax regime
Corporate income tax (CIT): 17% national rate. Municipal business tax (impôt commercial communal, ICC): varies by commune; Luxembourg City applies ~7.94%, yielding combined ~24.94%. Smaller communes (e.g., Differdange, Mersch) offer lower ICC rates (6–6.75%). Net wealth tax: 0.5% on net assets exceeding €500m (for most holding companies, negligible or exempt under participation exemption).
Participation exemption: Dividends and capital gains from qualifying participations (≥10% or acquisition cost ≥€6m for real-estate SPVs; ≥€1.2m for others; 12-month holding period) are fully exempt from CIT. This is the backbone of luxembourg SOPARFI structures. Anti-avoidance: the subsidiary must be subject to comparable tax (not a tax-exempt entity) or conduct genuine economic activity (BEPS Action 5 nexus).
Withholding tax (WHT): 0% on outbound dividends if EU Parent–Subsidiary Directive applies (≥10%, 12-month holding) or treaty relief (most Luxembourg treaties eliminate WHT). Interest and royalty payments to non-residents: 0% WHT if EU Interest & Royalties Directive applies or treaty relief. Otherwise, 15% WHT (interest) or no WHT (royalties under domestic law, but thin-cap rules may recharacterise).
Transfer pricing & thin capitalisation: Luxembourg applies OECD TP Guidelines. Debt-to-equity ratios above 85:15 trigger recharacterisation of interest into dividends (subject to ICC and no deduction). Country-by-country reporting (CbCR) mandatory for groups with consolidated revenue ≥€750m. ATAD implementation: interest-deduction limitation (30% EBITDA), exit-tax rules, and hybrid-mismatch provisions constrain aggressive intra-group financing.
VAT: Standard rate 17%; reduced rates 14% (e.g., wine), 8% (certain services), 3% (food, pharma). Financial services, fund management, and insurance are VAT-exempt (no output VAT, but input VAT non-recoverable). Luxembourg company formation triggers VAT registration unless turnover is below €35,000 (rarely applicable for international structures).
OECD Pillar Two (GloBE): Effective 2024–2025, groups with €750m+ consolidated revenue face 15% global minimum tax top-up (Income Inclusion Rule, IIR; Undertaxed Profits Rule, UTPR). Luxembourg's ~24.94% rate typically satisfies GloBE, but SOPARFI dividends (0% effective rate under participation exemption) may trigger substance-based income exclusion (SBIE) calculations and safe-harbour tests.
CFC & UK/US nexus: UK CFC rules (post-2025 Finance Act): Luxembourg holding companies with profits >£500,000 and <75% qualifying loan relationships face attribution unless genuine economic activities (CIGA) and local decision-making are proven. US Subpart F & GILTI: US persons owning ≥10% of a Luxembourg CFC must include Subpart F income (passive income, certain services) and GILTI (tested income less QBAI deduction) on Form 5471. PFIC: Luxembourg S.à r.l. or SOPARFI may be PFIC (passive income ≥75%); QEF or mark-to-market elections mitigate punitive tax, but require annual Form 8621. FATCA: Luxembourg IGAs mandate FFI reporting; non-compliant entities face 30% WHT on US-source payments.
costi dettagliati
Detailed costs
Luxembourg incorporation and maintenance costs reflect the jurisdiction's position as a regulated EU financial centre with rigorous compliance standards. The combined corporate income tax (CIT) and municipal business tax (MBT) typically reaches 24.94% in Luxembourg City, though rates vary by commune. Initial setup fees are higher than mass-market jurisdictions owing to notarial requirements, local registered office obligations, and mandatory publication in the Recueil électronique des sociétés et associations (RESA). Annual compliance costs include statutory audit requirements for most SARLs and SAs exceeding size thresholds, mandatory filing of tax returns and annual accounts, and ongoing registered agent fees. Banking introductions require substantial documentation and typically involve video-verification interviews; Luxembourg banks apply enhanced due diligence for non-resident directors. US founders must budget for dual reporting (IRS Form 5471, FinCEN FBAR) and should anticipate GILTI or Subpart F implications if the structure holds passive income. UK founders planning post-2025 remittance-basis claims must demonstrate genuine Luxembourg substance to avoid CFC apportionment under TIOPA 2010 Part 9A.

setup step by step
Step-by-step incorporation process
Luxembourg company formation follows a notarial process governed by the loi du 10 août 1915 concernant les sociétés commerciales (as amended). The most common vehicle for international founders is the SARL (société à responsabilité limitée), requiring minimum share capital of €12,000 (paid on incorporation). SAs (société anonyme) require €30,000 capital and a board structure suitable for larger operations. All Luxembourg entities must appoint a local registered office (domiciliation) and file articles of association notarised by a Luxembourg notary. The Trade and Companies Register (Registre de Commerce et des Sociétés, RCS) issues the registration certificate, which triggers RESA publication. Corporate tax registration and VAT registration (if applicable) follow incorporation. Timeline is typically 3–4 weeks from documentation to operational bank account, assuming no queries on UBO declarations.
- 1
Name reservation & documentation
Reserve company name with RCS (online via Guichet.lu), prepare articles of association, collect notarised copies of passports and proof of address for all shareholders and managers. Apostille/legalisation required for non-EU documents.
- 2
Share capital deposit & notarisation
Open blocked bank account and deposit minimum capital (€12,000 SARL / €30,000 SA). Attend notarial deed execution in Luxembourg or grant notarised power of attorney. Notary verifies identity, reads deed, collects signatures.
- 3
Trade Register filing & RESA publication
Notary files incorporation deed, articles, and managers' declarations with RCS. Registration number issued within 3–5 working days. Legal notice published automatically in RESA; publication fee ~€150–€200.
- 4
Tax registration
Apply for corporate income tax number and municipal business tax registration via ACD (Administration des contributions directes). VAT registration (if turnover >€35,000 or opted) via AED. Processing 1–2 weeks.
- 5
Domiciliation & local office
Execute registered office agreement with licensed domiciliation agent. Agent provides physical address, mail handling, and statutory representation. Economic substance packages typically include local phone number and meeting facilities.
- 6
Corporate bank account opening
Submit KYC dossier (certified articles, RCS extract, UBO declaration, business plan, source-of-funds evidence) to Luxembourg bank. Video interview with all authorised signatories. Account activation 6–12 weeks if approved.
economic substance
Economic substance and compliance
Luxembourg does not impose a standalone economic substance regime equivalent to offshore jurisdictions, but EU Anti-Tax Avoidance Directives (ATAD I & II) and OECD BEPS standards demand genuine commercial rationale and adequate local presence to access treaty benefits. The tax authorities (Administration des contributions directes) apply the "effective place of management" test: board meetings must occur in Luxembourg with a majority of directors resident or physically present, strategic decisions documented in minutes, and core income-generating activities (CIGA) conducted locally or demonstrably supervised from Luxembourg. Substance deficiencies trigger CFC exposure for UK and EU shareholders under ATAD Article 7 / TIOPA 2010 s.371EB, and potential disallowance of treaty benefits under Principal Purpose Test (PPT) under MLI.
US founders holding >10% face IRS Form 5471 annual reporting, GILTI inclusion on "tested income" exceeding QBAI deductions, and potential Subpart F treatment for passive income. FATCA reporting (Form 8938) applies if aggregate foreign financial assets exceed thresholds. Luxembourg entities holding non-US mutual funds trigger PFIC rules (Form 8621), often resulting in punitive taxation. Professional advice on check-the-box elections and hybrid mismatches is essential.
UK founders must demonstrate "sufficient substance" to avoid CFC apportionment: premises, employees, and expenditure proportionate to activity. Post-April 2025, remittance-basis claims require arm's-length dealings and genuine Luxembourg decision-making. HMRC increasingly challenges holding structures lacking operational staff. Transfer pricing documentation (TP) is mandatory for related-party transactions; Luxembourg tax rulings are public since 2021, reducing opacity. Annual filing includes bilan (balance sheet), profit & loss, tax annexes, and—for entities exceeding two of: €8.8m turnover, €4.4m balance sheet, 50 employees—statutory audit under EU Directive 2013/34. Non-compliance triggers RCS penalties and potential striking-off. Founders should budget for local accountancy firms familiar with DAC6 disclosure (mandatory reporting of cross-border tax arrangements) and BEPS 2.0 Pillar Two readiness (15% minimum tax effective 2024–2025 for groups >€750m consolidated revenue).
banking
Banking and account opening
Luxembourg offers a mature banking sector with universal banks (BGL BNP Paribas, ING Luxembourg, Banque de Luxembourg), private banks (KBL, Quintet), and specialised institutions serving corporate clients. For funds and SPVs, custodian banks (State Street, Northern Trust, CACEIS, RBC Investor Services) dominate, offering UCITS and alternative investment fund administration alongside banking. Minimum deposits for corporate accounts range from €10,000 for standard SARLs to €100,000+ for multi-currency treasury accounts at private banks.
KYC requirements are stringent: UBO declarations (minimum 25% threshold), audited financials for substance verification, detailed business plans for holding structures, and CRS/FATCA compliance. Expect 4–8 weeks for account opening; substance without local director or office triggers enhanced due diligence. US-person shareholders face FATCA-compliant reporting obligations; banks may decline accounts if the entity qualifies as a passive NFFE without Form W-8BEN-E.
EMIs—Wise Business (multi-currency but limited inbound SEPA for Luxembourg entities), Airwallex, Currenxie—serve as interim solutions but lack custodian facilities required for regulated funds. Offshore alternatives in Switzerland (Dukascopy, Swissquote) or Singapore attract founders requiring non-EU privacy layers, though CRS exchange applies. UK substance clients: remittance-basis planning post-April 2025 demands segregated non-UK source accounts; Luxembourg banks accommodate this via fiduciary structures. For US founders, FBAR (FinCEN 114) triggers at $10,000 aggregate foreign balance; FATCA Form 8938 at $200,000 (joint filers abroad). PFICs in Luxembourg mutual fund holdings require QEF elections to avoid punitive taxation.
Recommendation: establish banking relationships pre-incorporation, especially for regulated vehicles requiring pre-licensing bank comfort letters to the CSSF.
a chi adatta
Who this jurisdiction suits
Luxembourg suits fund managers launching UCITS, AIFs, or RAIFs requiring EU passporting under AIFMD; the CSSF supervises 3,800+ investment vehicles. Holding companies consolidating EU/global subsidiaries benefit from the participation exemption (0% withholding on dividends/gains if >10% held >12 months, subject anti-abuse under ATAD) and 80+ tax treaties. IP licensing vehicles exploit the 80% net wealth tax exemption for qualifying IP, though substance requirements (local economic employer, decision-makers) have tightened post-BEPS.
Family offices and private wealth structures use SOPARFIs (tax-exempt holding SPVs) combined with civil-law foundations (fondations) for succession planning; Luxembourg permits reserved-power trusts since 2003, attracting common-law practitioners. SPACs and listed vehicles dominate the Luxembourg Stock Exchange (3rd-largest for fund listings globally).
US founders: Luxembourg is not a low-tax jurisdiction under Subpart F (passive income rules) or GILTI, but suits those requiring EU substance for CFC deferrals or treaty-shopping mitigation. The US–Luxembourg treaty offers 5% dividend withholding (>10% ownership) and full interest/royalty exemptions, valuable for leveraged structures. UK founders: post-April 2025 FIG reforms make Luxembourg holdings tax-efficient if structured as non-close companies with <40% UK-source income, avoiding UK CFC charges via acceptable distribution policy.
Not suitable for e-commerce, digital services, or operational trading without genuine Luxembourg establishment—transfer pricing scrutiny is severe.
red flags
When this is not the right choice
Operational businesses seeking low effective tax rates: the 24.94% combined corporate rate (17% base + 7% municipal + 1.19% solidarity surcharge) offers no advantage over Ireland (12.5%), Cyprus (12.5%), or UAE (9%). Digital services companies face Pillar Two top-up taxes at 15% globally; Luxembourg's headline rate provides minimal room for optimisation.
Asset protection or privacy-first clients: Luxembourg implements public UBO registers (RBE) with 25% threshold, full CRS exchange, and EU5 Anti-Money Laundering Directive compliance. Offshore alternatives (BVI, Cayman, Jersey) offer superior confidentiality within FATCA/CRS constraints.
Founders without €12,000+ annual budget: SARL maintenance (audit exemption threshold €8.8M turnover, but most banks demand audited accounts), legal/accounting fees (€4,000–8,000 p.a.), and director fees (€6,000–15,000 for licensed director) exceed Cyprus or Malta costs. US persons with small holding companies (<$2M assets) face disproportionate Form 5471/8865 compliance costs versus US LLC transparency.
Rapid formation needs: 4–6 weeks minimum (notarisation, Registre de Commerce, VAT registration) versus Estonia e-Residency (5 days) or UK Companies House (24 hours). Urgent fund launches require parallel shelf-company acquisition (€3,500–6,000).
aggiornamenti 2026
Regulatory updates for 2026
Pillar Two (15% minimum tax) applies from 1 January 2024 for Luxembourg groups with €750M+ consolidated revenue; IIR and UTPR mechanics are now operational. SOPARFIs and pure holding companies with no employees face substance-over-form challenges under the Qualified Domestic Minimum Top-Up Tax (QDMTT). The Luxembourg tax authority issued guidance requiring economic employer tests for IP structures: licensing entities must employ qualified personnel making strategic decisions locally.
DAC8 (Directive 2023/2226) extends automatic exchange to crypto-asset service providers from 1 January 2026; Luxembourg-regulated custodians (BitFlyer Europe, Bitstamp) must report transactions to resident UBOs. Unshell directive (ATAD3) proposes minimum substance gateways: entities with <€750K income, outsourced administration, and no exclusive offices lose treaty/directive benefits. Draft law expected Q2 2025; compliance deadline 1 January 2027.
AML reforms: the RBE register now cross-references tax residency certificates; discrepancies trigger CTIF (financial intelligence unit) alerts. New CDD rules for funds require LEI renewal evidence and investor risk-profiling under MiFID II.
CSSF supervision: the 2025–2027 strategic plan prioritises SupTech/RegTech for AIFs, mandating AIFMD quarterly reporting via electronic templates (ORTC system). Small RAIFs (<€100M AUM) face proportionate supervision but must appoint Luxembourg-authorised AIFM depositaries.
For US founders: the US Treasury issued final regulations on foreign tax credit baskets (2023), limiting Luxembourg participation exemption interplay with GILTI; technical adjustments required for post-2026 controlled foreign corporation planning. UK founders: HMRC's revised CFC gateway tests (Finance Act 2025) scrutinise Luxembourg SOPARFI distributions under the 'acceptable distribution policy' exemption—quarterly dividend policies now expected.
