Belgium Shares and Securities Tax Guide

Belgian taxation of shares and securities — Belgium imposes several taxes on securities holdings and transactions. The guide covers: the securities accounts tax (the "effectenbelasting" / "taxe sur les comptes-titres" — the annual 0.15% tax on securities accounts with an average value exceeding €1M; the tax is due on accounts held with Belgian financial institutions — KBC, BNP Paribas Fortis, ING, Belfius, Argenta — and on foreign accounts held by Belgian residents; the tax is calculated on the average value of the securities in the account during the year; the first €1M is exempt), the stock exchange tax (the "beurstaks" / "taxe sur les opérations de bourse" / "TOB" — a transaction tax on the purchase and sale of securities through a Belgian financial intermediary: 0.12% for equities and ETFs (capped at €1,300 per transaction), 0.35% for bonds (capped at €1,300), 0.12% for options, 0% for certain government bonds), the dividend withholding tax (the "roerende voorheffing" / "précompte mobilier" — 30% final withholding tax on Belgian-source dividends; the 30% rate is the final tax for resident individuals — dividends are not reported in the personal income tax return for most taxpayers; the 30% is the final tax, and the first €800 (2026) of dividends per taxpayer is exempt from the withholding tax), the capital gains tax on shares (Belgium does NOT impose a capital gains tax on the normal management of private assets — the "normaal beheer van privévermogen" / "gestion normale d'un patrimoine privé" — capital gains on shares held as a private investment are tax-exempt; BUT capital gains on shares held as a professional activity (the "speculatief" / "speculatie" — frequent trading or trading beyond the normal management of private assets) may be taxed at the progressive rates (25–50%), and capital gains on substantial shareholdings (≥25% — see the corporate tax and the exit tax rules) are subject to the 16.5% exit tax or the 25% corporate tax), and the reporting obligations (the "aangifte effectenrekeningen" / "déclaration comptes-titres" — the annual reporting of securities accounts by Belgian financial institutions to the FOD Financiën / SPF Finances; the CRS automatic exchange of foreign securities accounts).

Belgium's securities tax regime is relatively favourable for long-term investors — no capital gains tax on normal portfolio management — but the 0.15% securities accounts tax and the 30% dividend withholding tax add to the holding costs. All amounts in Euros (EUR). For related reading, see our Investment Box 3 Guide →, Personal Tax Guide →, and Crypto Tax Guide →.

Securities Accounts Tax (Effectenbelasting / Taxe sur les Comptes-Titres)

  • The 0.15% annual tax: Since 2021 (confirmed by the Constitutional Court in 2022), Belgium imposes an annual 0.15% tax on securities accounts with an average value exceeding €1M (the "effectenbelasting" / "taxe sur les comptes-titres" — the securities accounts tax). The tax is calculated on the average value of financial instruments held in the account during the reference period (the calendar year). The first €1M of the account value is exempt — the tax applies only to the portion above €1M. The tax applies to: (a) accounts held with Belgian financial institutions (the tax is automatically collected by the financial institution and remitted to the FOD Financiën / SPF Finances), (b) accounts held with foreign financial institutions by Belgian residents (the taxpayer must self-declare — the "aangifte effectenbelasting" / "déclaration taxe comptes-titres" — in their annual personal income tax return). The tax rate of 0.15% means that an account with an average value of €2M pays 0.15% × €1M = €1,500 per year.
  • Covered financial instruments: The securities accounts tax covers: (a) shares and equities (including ETFs), (b) bonds and debentures, (c) investment fund units (the "ICB's" / "OPC" — the Belgian investment funds and the foreign UCITS), (d) derivatives (options, futures, and other financial contracts), (e) cash held as collateral (but not regular cash deposits). NOT covered: (a) cash deposits (the "spaarrekeningen" / "comptes d'épargne"), (b) insurance policies (the "tak 21" / "branche 21" and "tak 23" / "branche 23" — life insurance contracts), (c) pension savings (the "pensioensparen" / "épargne-pension"), (d) real estate.
  • Multiple accounts and aggregation: Taxpayers with multiple securities accounts (with different banks) must aggregate the values to determine whether the €1M threshold is exceeded. The aggregation rule applies to: (a) all accounts held by the taxpayer (including joint accounts — the taxpayer's share of the account), (b) accounts held by the taxpayer's spouse or legal cohabitant (the values are aggregated for the household), (c) accounts held by minor children. The taxpayer must self-declare the aggregated value if it exceeds the threshold.

Stock Exchange Tax (Beurstaks / TOB)

  • Transaction tax rates: The stock exchange tax (the "beurstaks" / "taxe sur les opérations de bourse" / "TOB") applies to the purchase and sale of securities through a Belgian financial intermediary. The rates: (a) 0.12% for equities (individual shares) and ETFs — capped at €1,300 per transaction, (b) 0.35% for bonds (including government bonds, corporate bonds, and convertible bonds) — capped at €1,300 per transaction, (c) 0.12% for options and other derivative contracts (the premium is the taxable base), (d) 0% for Belgian government bonds (the "lineaire obligaties" / "obligations linéaires" — OLOs). The tax is collected by the financial intermediary and remitted to the FOD Financiën / SPF Finances. The tax is NOT due on transactions executed through a foreign broker (e.g., Degiro, Interactive Brokers, unless they have a Belgian licence and are required to collect the TOB).
  • Exemptions: The stock exchange tax does NOT apply to: (a) the primary market (the issue of new shares or bonds — the TOB is a secondary market tax only), (b) the intra-group transfers of securities, (c) the liquidation distributions (the distribution of securities by a company in liquidation), (d) transactions by professional market makers (the "marktmakers" / "teneurs de marché"), (e) transactions with a value of less than €0.01 per share (de minimis exemption).

Dividend Withholding Tax and Capital Gains

  • 30% roerende voorheffing: Belgian-source dividends are subject to 30% withholding tax (roerende voorheffing / précompte mobilier). The 30% rate is the final tax for resident individuals — the dividend is NOT reported in the personal income tax return (the "eindbelasting" / "impôt final" — the final withholding tax system). The first €800 (2026) of dividends per taxpayer is exempt from the withholding tax (the "belastingvrije som voor dividenden" / "quotité exonérée sur les dividendes"). The exemption is applied automatically by the financial institution if the dividend is paid through a Belgian intermediary. The 30% rate may be reduced under an applicable tax treaty for non-residents.
  • Capital gains on shares — the general rule: Belgium does NOT tax capital gains on the normal management of private assets (the "normaal beheer van privévermogen" / "gestion normale d'un patrimoine privé"). This means: (a) capital gains on shares held as a private investment (buy-and-hold, occasional rebalancing) are tax-exempt, (b) capital gains on shares held as a professional activity (the "speculatie" / "spéculation" — frequent trading, day trading, trading as a main source of income) are taxed at the progressive rates (25–50%), (c) capital gains on substantial shareholdings (≥25%) are subject to the 16.5% exit tax or the 25% corporate tax if held through a company. The distinction between "normal management" and "speculation" is a facts-and-circumstances test — the FOD Financiën / SPF Finances considers: the frequency of transactions, the holding period, the use of leverage, the taxpayer's professional background, and the income from the activity.

Reporting Obligations

  • Automatic reporting by Belgian financial institutions: Belgian banks and brokers automatically report their clients' securities accounts to the FOD Financiën / SPF Finances (the "aangifte effectenrekeningen" / "déclaration comptes-titres"). The reported data includes: the account value at 31 December, the account holder's name and national register number, the types of securities held, and the income (dividends, interest) paid during the year. The data is used for: (a) the securities accounts tax assessment (the 0.15% tax), (b) the CRS exchange with foreign tax authorities. The taxpayer does not need to file a separate securities account return — the financial institution handles it.
  • CRS and foreign accounts: Belgian residents with securities accounts abroad are subject to the Common Reporting Standard (CRS). The foreign financial institution reports the account to its local tax authority, which exchanges the data with the FOD Financiën / SPF Finances. The taxpayer must also self-report foreign securities accounts in the personal income tax return (the "aangifte buitenlandse effectenrekeningen" / "déclaration comptes-titres étrangers") — failure to report can result in a penalty of €250–€3,000 per year of non-reporting.
