Belgium Tax Treaties Guide

Belgium's extensive tax treaty network — Belgium has concluded over 95 double tax treaties (dubbelbelastingverdragen / conventions fiscales préventives), making it one of the most well-connected treaty jurisdictions in Europe. The guide covers: treaty relief for cross-border income (dividends — the standard treaty rate is 15%, with some treaties providing 5–10% for substantial holdings; interest — typically 10–15%, with some treaties providing 0%; royalties — typically 10–15%, with some treaties providing 0% for certain types), the BEPS Multilateral Instrument (MLI) impact on Belgian treaties (the MLI entered into force in Belgium on 1 January 2025 — the "principal purpose test" / PPT applies to all covered treaties), the most significant treaty partners (the US treaty — 15% direct dividend rate, 5% for ≥10% holdings; the UK treaty — 0% on interest and royalties; the Netherlands treaty — 5% direct dividend rate, 0% on interest; the France treaty — the frontier worker rules and the 0% dividend rate for ≥10% holdings; the Germany treaty — the 183-day frontier worker rule; the Luxembourg treaty — the full integration rules for the Belgian-Luxembourg economic union), the tie-breaker rules for dual-resident companies (the "place of effective management" test under the OECD Model), the mutual agreement procedure (MAP — the "onderling overleg" / "procédure amiable" for resolving treaty disputes), and the exchange of information provisions (Article 26 — full exchange of banking information for all treaty partners).

Belgium's treaty network is central to its role as a headquarters and holding company jurisdiction. All amounts in Euros (EUR). For related reading, see our Cross-Border Tax Guide →, Holding Companies Guide →, Transfer Pricing Guide →, and Non-Resident Taxation Guide →.

Treaty Relief for Dividends, Interest, and Royalties

  • Dividends: Belgian domestic law imposes a 30% withholding tax on dividend distributions. Under Belgium's tax treaties, the rate is typically reduced to: (a) 15% for portfolio investments (the standard treaty rate — applicable to most treaty partners), (b) 5–10% for substantial holdings (typically ≥10% or ≥25% of the share capital, depending on the treaty), (c) 0% under certain treaties (e.g., the EU Parent-Subsidiary Directive — no withholding tax on dividends paid by a Belgian subsidiary to an EU parent company holding ≥10% for at least 1 year). The most favourable treaty rates: US (15% direct, 5% for ≥10%), UK (15% direct, 5% for ≥10%, and 0% under certain conditions for pension funds), Netherlands (5% for ≥10%), France (0% for ≥10%), Luxembourg (0% for ≥10% under the Parent-Subsidiary Directive).
  • Interest: Belgian domestic law imposes a 30% withholding tax on interest payments. Under Belgium's tax treaties, the rate is typically reduced to: 10–15% for most treaty partners. Several treaties provide a 0% rate for certain types of interest: (a) interest paid to the government or central bank (the "staatslening" / "emprunt d'État"), (b) interest on bonds publicly issued, (c) interest on bank loans and trade credits. The UK treaty provides 0% on interest (no withholding tax). The Netherlands treaty provides 0%. The Luxembourg treaty provides 0%. The US treaty provides 0% for certain interest (banking and trade). The OECD BEPS MLI may require the principal purpose test for all interest claims.
  • Royalties: Belgian domestic law does not impose withholding tax on royalties paid to non-residents (except for certain deemed royalties under Belgian domestic law — the "royalty" definition in the WIB/92). However, Belgium's treaties typically provide for a reduced rate of 5–10% on royalties. The UK treaty provides 0%. The Netherlands treaty provides 0%. The France treaty provides 0% for certain royalties (copyright, patents). The US treaty provides 0%. The Parent-Subsidiary Directive also applies to certain royalty payments between associated EU companies.

BEPS MLI Impact on Belgian Treaties

  • The MLI in Belgium: The OECD BEPS Multilateral Instrument (MLI) entered into force in Belgium on 1 January 2025. The MLI modifies over 70 of Belgium's bilateral tax treaties (the "Covered Tax Agreements" — CTA). The key changes: (a) the principal purpose test (PPT) — a general anti-abuse rule that denies treaty benefits if obtaining the benefit was one of the principal purposes of an arrangement or transaction, (b) the treaty abuse provisions — the simplified limitation on benefits (LOB) clause in certain treaties, (c) the mutual agreement procedure (MAP) improvements — the mandatory binding arbitration clause for unresolved MAP cases within 2 years, (d) the hybrid mismatch provisions — the denial of treaty benefits for income that is not treated as income in the source state (the "dual-resident" provisions).
  • Principal Purpose Test (PPT): The PPT applies to all MLI-covered treaties. Under the PPT, treaty benefits (reduced withholding rates, exemption from tax) are denied if "obtaining that benefit was one of the principal purposes of any arrangement or transaction" — unless the taxpayer can demonstrate that granting the benefit is consistent with the object and purpose of the treaty. This is a facts-and-circumstances test — taxpayers must document the business rationale for cross-border structures. The FOD Financiën / SPF Finances has issued guidance on the PPT application (Circular 2025/C/1).

Key Treaty Partners

  • US-Belgium Treaty: The US-Belgium treaty (2006, as amended by the 2021 protocol) provides: (a) dividends — 15% direct rate, 5% for ≥10% voting stock, (b) interest — 0% for certain interest (bank loans, trade credits), 15% for other interest, (c) royalties — 0% for certain royalties (computer software, patents), 10% for other royalties, (d) the limitation on benefits (LOB) clause — the company must meet the "qualified person" test (publicly traded, or owned by qualified persons, or the "base erosion" test). The treaty also provides for the exchange of banking information under FATCA.
  • UK-Belgium Treaty: The UK-Belgium treaty (2014, as amended by the MLI) provides: (a) dividends — 15% direct rate, 5% for ≥10% holdings, 0% for pension funds, (b) interest — 0% (no withholding tax), (c) royalties — 0% (no withholding tax). The UK treaty is one of Belgium's most favourable — ideal for cross-border structures involving royalty payments and intragroup financing.
  • Netherlands-Belgium Treaty: The NL-BE treaty (2004, as amended by the 2014 protocol and the MLI) provides: (a) dividends — 5% for ≥10% holdings, 15% for portfolio holdings, (b) interest — 0% (no withholding tax), (c) royalties — 0% (no withholding tax). The treaty also contains the frontier worker provisions (the grensarbeidersregeling) and the special rules for cross-border telework.
  • France-Belgium Treaty: The FR-BE treaty (1964, as amended by the 2002 protocol and the MLI) provides: (a) dividends — 0% for ≥10% holdings (under the EU Parent-Subsidiary Directive), 15% for portfolio holdings, (b) interest — 10%, (c) royalties — 0% for copyright and patent royalties, 10% for other. The treaty also contains the frontier worker rules for the BE-FR border region.
  • Germany-Belgium Treaty: The DE-BE treaty (1967, as amended by the 2014 protocol and the MLI) provides: (a) dividends — 0% for ≥10% holdings (under the EU Parent-Subsidiary Directive), 15% for portfolio, (b) interest — 10%, (c) royalties — 5%. The treaty also contains the 183-day frontier worker rule for the BE-DE border region.

Tie-Breaker Rules and MAP

  • Dual-resident companies: Under the OECD Model Convention (Article 4(3)), a company that is resident in both Belgium and another country (dual residence) is treated as resident in the country where its place of effective management (POEM) is located. The MLI has replaced the POEM test for covered treaties with a "mutual agreement procedure" approach — the competent authorities of both states must determine the treaty residence by mutual agreement, considering the POEM, the place of incorporation, and any other relevant factors. Belgium's domestic law also provides for a POEM test (Article 2, §1, 5° of the WIB/92).
  • Mutual Agreement Procedure (MAP): If a taxpayer considers that the actions of the Belgian tax authorities or a treaty partner result in taxation not in accordance with the treaty, the taxpayer can file a MAP request (the "verzoek onderling overleg" / "demande de procédure amiable"). The request is filed with the FOD Financiën — the Centrale Dienst Buitenlandse Aangelegenheden (Central Service for Foreign Affairs). The MAP process: (a) the taxpayer files the request within 3 years of the first notification of the double taxation, (b) the Belgian competent authority (the FOD Financiën) negotiates with the treaty partner's competent authority, (c) if no agreement is reached within 2 years, the taxpayer may request binding arbitration (under the MLI or the EU Arbitration Convention). The MAP can cover: transfer pricing adjustments, treaty interpretation disputes, residence conflicts, and the application of the PPT.
