Corporate IRC is 17% plus 7% solidarity plus 6.75% municipal business tax, combining to ~24.94% in Luxembourg City. Standard TVA rate is 17% (lowest in the EU). Luxembourg dominates European fund-servicing, hosting ~EUR 5 trillion in investment fund assets as the world's second-largest fund domicile. SOPARFI holding companies benefit from a broad participation exemption. IP-box effective rate is 5.2% on qualifying income. Pillar Two QDMTT applies from 31 December 2023.

Luxembourg at a glance

World's #2 investment fund domicile and EU financial centre with a 23-bracket progressive PIT.

Luxembourg is an EU founding member (Treaty of Rome, 1957) and Schengen founding signatory. The Grand Duchy hosts the EU Court of Justice, the European Investment Bank, the European Court of Auditors, and Eurostat. Population is approximately 660,000 — Europe's third-smallest sovereign state. The euro has been the currency since the eurozone launched on 1 January 1999, replacing the Luxembourg Franc (LUF). Constitutional monarchy under Grand Duke Henri.

World's #2 fund domicile

~EUR 5 trillion in investment fund assets under administration

Luxembourg's UCITS and AIFMD fund platforms domicile roughly EUR 5 trillion in assets, second only to Ireland. CSSF supervises investment managers; Reserved Alternative Investment Funds (RAIFs), SICAVs, ELTIFs, and SIF frameworks give fund promoters extensive structuring options. Fund services represent over 30% of national GDP.

Who is the tax authority in Luxembourg?

The Administration des Contributions Directes (ACD) administers direct taxes — personal income tax, corporate income tax, municipal business tax, and the solidarity surcharge. The Administration de l'Enregistrement, des Domaines et de la TVA (AED) administers VAT, registration duties, and other indirect taxes. Customs fall under the Administration des Douanes et Accises.

The primary personal e-filing portal is MyGuichet.lu. Substantive law rests on the Income Tax Law (Loi modifiee du 4 decembre 1967 concernant l'impot sur le revenu, LIR) and successive amendments. The credentialed professions are regulated by the Institut des Reviseurs d'Entreprises (IRE) and the Ordre des Experts-Comptables (OEC).

What is the Luxembourg tax year and when are returns due?

The tax year is the calendar year (1 January to 31 December). Personal income tax returns are due 31 December of the year following the tax year — a generous window compared to most EU peers. Corporate annual returns are due 31 May of the year following fiscal year-end.

Luxembourg tax year — key filing dates Luxembourg tax year — January through December JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC C 31 May Corp due annual IRC ! 31 Dec PIT due IRPP PAYE withheld monthly (RTS) · TVA-registered: monthly or quarterly PIT form: Deklaratioun fiscal · Corporate: annual return to ACD · Frontaliers: cross-border declarations December is Luxembourg's heaviest PIT month — IRPP due in full by 31 December.

VAT returns are filed monthly (for businesses above EUR 620,000 annual turnover) by the 19th of the following month, or quarterly below that threshold. Withholding tax (Retenue a la Source, RTS) on employment income applies monthly.

Who counts as a Luxembourg tax resident?

Under the LIR, an individual is a Luxembourg tax resident if either condition applies:

  • They maintain a domicile or habitual residence in Luxembourg
  • They are physically present in Luxembourg for at least 6 months

Residents are taxed on worldwide income. Non-residents pay tax only on Luxembourg-source income. Treaty tie-breakers apply where two jurisdictions both claim residency.

Luxembourg operates three tax classes that affect personal allowances and brackets. Class 1 applies to single individuals; Class 1a to single parents with dependants; Class 2 to married couples filing jointly. The tax-class choice has material consequences — especially for the 23-bracket rate structure.

A distinctive local issue is the frontalier workforce. Approximately 45% of Luxembourg's working population are cross-border commuters (frontaliers) from France, Belgium, and Germany. Each group has different treaty obligations: French frontaliers are taxed in Luxembourg on their Luxembourg-sourced salary; certain Belgian and German rules differ. A qualified Tax-Adviser is usually needed to reconcile home-country and Luxembourg obligations.

What are the personal income tax rates?

Luxembourg operates one of the most granular personal income tax structures globally — 23 progressive bands ranging from 0% to 42%. This is far more brackets than any peer in the EU financial-centre cohort.

Yearly income (EUR) — Class 1 (single)Marginal rate
Up to 12,4380%
12,439 to ~14,5088%

On top of the 42% marginal rate, a solidarity surcharge (contribution au fonds pour l'emploi) applies: 7% on assessed PIT for most residents (rising to 9% for high earners above EUR 150,000 employment income). The combined effective top marginal rate reaches approximately 45-48%.

Social security contributions (CCSS) add approximately 12.45% on the employee side and a matching employer contribution plus accident-insurance variable. Investment income from Luxembourg companies faces a 15% withholding with a 50% partial-income-inclusion exemption.

How does Luxembourg corporate tax work?

Luxembourg's corporate income tax (IRC) combines three layers: 17% IRC + 7% solidarity surcharge on IRC + 6.75% municipal business tax (ICC) in Luxembourg City. The all-in effective combined rate in Luxembourg City is approximately 24.94%. Rates in other municipalities differ because the ICC varies by commune.

IRC base
17%

Corporate income tax rate from 2025. Raised from 15% over successive reforms to align with Pillar Two floor.

Solidarity + ICC
+7.95%

7% solidarity surcharge on IRC + 6.75% municipal business tax (ICC) in Luxembourg City. ICC rate varies by commune.

Combined LUX City
~24.94%

All-in effective rate in Luxembourg City. Among the lower EU combined rates after Ireland 12.5%, Hungary 9%, Cyprus 12.5%.

Withholding tax on dividends paid to non-residents is 15% (0% under the EU Parent-Subsidiary Directive for qualifying EU/EEA participations). Tax losses carry forward for 17 years (post-2017 reform; pre-2017 losses retain indefinite carryforward). Net Wealth Tax (Impot sur la fortune) applies at 0.5% on net corporate wealth above EUR 500 million and 0.05% above that.

The OECD Pillar Two Qualified Domestic Minimum Top-up Tax (QDMTT) and Income Inclusion Rule (IIR) apply from 31 December 2023 under the Loi du 22 decembre 2023 transposing EU Directive 2022/2523. The Undertaxed Profits Rule (UTPR) applies from 31 December 2024.

SOPARFI, IP box, and holding-company regimes

Luxembourg's SOPARFI (Societe de Participations Financieres) is the workhorse holding vehicle. A SOPARFI is a fully taxed Luxembourg company that benefits from a broad participation exemption: qualifying dividends and capital gains from subsidiaries are 95-100% exempt from IRC, subject to minimum participation thresholds (10% or EUR 1.2 million cost).

SOPARFI — participation exemption

Qualifying dividends and capital gains from subsidiaries are 95-100% exempt from IRC. Most widely used Luxembourg holding structure for MNE groups and PE fund portfolios.

SPF — family wealth vehicle

Societe de gestion de Patrimoine Familial — subject to subscription tax rather than IRC. Available only to private individuals and family groups. Not for commercial activities.

IP box — 5.2% effective rate

Under Article 50ter LIR, 80% of qualifying IP income is exempt from IRC — producing an effective rate of approximately 5.2% on qualifying income. OECD nexus-aligned; patents and certain other qualifying IP apply.

SICAR / SCS / SCSp — PE structures

Investment company in risk capital (SICAR) and special limited-partnership structures (SCS, SCSp) used for private equity and venture-capital fund structures. CSSF-supervised.

What about TVA (VAT) and indirect taxes?

Luxembourg's Taxe sur la Valeur Ajoutee (TVA) carries the lowest standard rate in the EU at 17% (raised from 16% as of 1 January 2024). Four rate bands apply:

RateApplies to
17%Standard — most goods and services
14%Intermediate — selected categories
8%First reduced — foodstuffs, accommodation, books, pharmaceuticals
3%Super-reduced — specified essentials including certain food, medicines, restaurants
0%Exports (zero-rated, not exempt)

Mandatory TVA registration applies above EUR 35,000 annual turnover. The EU OSS and IOSS regimes cover cross-border B2C digital supplies. Registration duties (administered by AED) apply to real-estate transactions and certain financial instruments.

How are cryptoassets taxed?

Luxembourg applies a hold-duration rule to individual cryptoasset gains under the LIR. Gains on cryptoassets held for fewer than 6 months are treated as speculative income and subject to ordinary progressive PIT rates. Gains on cryptoassets held for more than 6 months are generally tax-exempt for individual non-business holders — a distinctive feature relative to most EU peers.

MiCA + CSSF

EU MiCA Regulation — effective December 2024

The EU Markets in Crypto-Assets (MiCA) Regulation became fully effective on 30 December 2024. Crypto-asset service providers (CASPs) operating in Luxembourg are supervised by the CSSF. Luxembourg's pre-MiCA fund-licensing framework for crypto funds under UCITS/AIFMD gave it an early-mover advantage that continues under the MiCA-era harmonised regime.

Mining and staking income are treated as commercial income or other income depending on the regularity and scale of the activity. Institutional crypto vehicles inside the UCITS or AIFMD fund frameworks fall under the fund-supervisory regime.

What is the Luxembourg treaty network?

Luxembourg maintains approximately 85 active bilateral double-tax conventions — one of the largest networks globally for a country of its size. The network reflects Luxembourg's historic role as a holding-company and fund-administration jurisdiction requiring broad coverage for inbound investment flows.

US treaty (1996) in red. Luxembourg MLI-ratified effective 1 August 2019. EU Parent-Subsidiary and Interest-Royalties Directives eliminate most intra-EU withholding for qualifying flows.

Luxembourg ratified the OECD Multilateral Instrument (MLI) on 9 April 2019; modifications entered force from 1 August 2019 for covered treaties. The Principal Purpose Test (PPT) and Simplified Limitation on Benefits clause apply to covered agreements. Luxembourg also benefits from the full suite of EU directives: Parent-Subsidiary, Interest and Royalties, Merger, and Anti-Tax Avoidance Directives.

Luxembourg's banking secrecy was effectively eliminated through CRS adoption effective 2017. DAC2 and automatic exchange of financial account information now cover all CRS-participating jurisdictions.

Where does Luxembourg sit in the EU financial-centre cohort?

Luxembourg anchors the EU financial-centre holding-company cohort alongside Ireland, the Netherlands, Malta, and Cyprus. The broader EU jurisdictions cluster into five archetypes based on tax positioning.

Meet a Luxembourg-resident taxpayer

Sophie, 38 — senior fund administrator at a Luxembourg SICAV manager

Sophie earns EUR 140,000 annually managing fund NAV calculations for a major UCITS umbrella fund. Under Luxembourg's 23-bracket PIT, most of her salary falls in the 39-42% bands. The solidarity surcharge adds 7%, pushing her effective top marginal rate close to 47%. She files through MyGuichet.lu by 31 December.

Sophie's employer operates a SOPARFI holding company that holds fund-manager stakes — dividends flow up the chain largely exempt from IRC under the participation exemption. The complexity of Class-1 filings, CCSS contributions, and investment-income withholding credit reconciliation led her to engage a Luxembourg OEC-registered Tax-Adviser.

Common pitfalls for individuals and businesses

Foreign companies and individuals encounter a consistent set of traps when operating in Luxembourg.

23-bracket PIT complexity

The most granular PIT structure in the EU. Small income movements between brackets have different marginal consequences at each step. The solidarity surcharge adds a second calculation layer on top of assessed tax.

Frontalier cross-border complexity

45% of Luxembourg's workforce are cross-border commuters. French, Belgian, and German frontaliers all have different treaty rules governing where their salary is taxed and how home-country declarations interact with Luxembourg filings.

Pillar Two QDMTT from Dec 2023

Luxembourg's holding-company prominence made it a priority jurisdiction for Pillar Two analysis. In-scope MNE groups (EUR 750M+ consolidated revenue) face QDMTT and IIR since 31 December 2023, with UTPR added from 31 December 2024.

Tax-class framework for PIT

Class 1 (single), Class 1a (single with dependants), and Class 2 (married joint) produce materially different tax outcomes. Incorrect class selection creates back-assessment risk. Expats who marry after arriving often fail to apply for Class 2 reclassification.

SOPARFI participation-exemption conditions

The participation exemption on dividends and capital gains requires meeting minimum participation thresholds (10% holding or EUR 1.2M acquisition cost) and a 12-month holding period. Substance requirements under EU ATAD and the PPT restrict structures lacking genuine economic activity.

IP box — nexus and qualifying-IP definition

The 80% exemption (5.2% effective rate) under Article 50ter LIR requires qualifying IP meeting OECD nexus ratios. Routine upgrades, trademarks, and non-patented branding don't qualify. Post-BEPS alignment means substance and R&D tracking are mandatory.

Crypto 6-month holding threshold

Individual crypto gains are only exempt if held over 6 months. Gains from sales within 6 months are ordinary income at progressive rates up to 42% plus solidarity. Accurate timestamp tracking on each acquisition tranche is required for the exemption to hold.

Net Wealth Tax on companies

Luxembourg's *Impot sur la fortune* (NWT) applies annually on corporate net wealth at 0.5% above EUR 500M and 0.05% above. This is layered atop IRC plus ICC. Many holding companies use a NWT minimum-reserve credit to partially offset the charge.

Loss carryforward 17-year cap

Post-2017 tax losses carry forward for a maximum of 17 years. Pre-2017 losses retain indefinite carryforward. Groups acquiring Luxembourg targets with old losses need to verify the vintage before factoring indefinite use into valuations.
