What Belgium Investors Need to Know in 2026
Belgium has one of Europe's most investor-friendly tax regimes: no capital gains tax on stocks for private investors. However, dividends are taxed at 30% withholding tax. Tax-efficient strategies focus on accumulating (non-dividend) ETFs.
The TOB (Taxe sur les Opérations Boursières / Taks op Beursverrichtingen) — Belgium's stock exchange tax — applies on most stock and ETF transactions: 0.12% for ETFs, 0.35% for stocks, 1.32% for some fixed-income. Factor this into your cost calculations.
Belgian investors should declare foreign broker accounts to the CAP (Centrale Aanspreekpunt). Non-compliance can trigger tax penalties.
