Belgium Gambling Winnings Tax Guide

the Belgian tax treatment of gambling winnings — Belgium has a unique approach: occasional gambling winnings (the "toevallige spelwinsten" / "gains de jeu occasionnels") are generally tax-exempt for casual players (the "particulier" / "individu" — an individual who plays for entertainment, not as a profession). The exemption is based on the principle that gambling is a "toevallige verrichting" / "opération occasionnelle" — an occasional transaction that is not part of the taxpayer's normal income. The guide covers: the tax exemption for casual gamblers (the general rule: winnings from lotteries, casinos, sports betting, poker — for a casual player — are NOT subject to personal income tax; the FOD Financiën / SPF Finances treats occasional gambling as "niet-beroepsmatige verrichtingen" / "opérations non professionnelles"), the professional gambling tax (if gambling is the taxpayer's main source of income or a regular, systematic activity — the "beroepsmatig" / "professionnel" gambling — the winnings are taxed as professional income at the progressive rates (25–50%), and the losses are deductible against the winnings), the casino tax (the "casinobelasting" / "taxe sur les casinos" — the operators pay a specific tax on each game — the "belasting op de spelen" / "taxe sur les jeux" — of 15% on gross gaming revenue for slot machines, 5% for table games), the online gambling licensing regime (the "vergunning kansspelen" / "licence jeux de hasard" — the Belgian Gaming Commission (Kansspelcommissie / Commission des Jeux de Hasard) issues licences for online gambling operators; the operators are subject to a 11% tax on gross gaming revenue for online games; the players must be registered with the EPIS (Excluded Persons Information System — the "uitsluitingsregeling" / "système d'exclusion"), and the use of unlicensed offshore gambling websites is prohibited — Belgian banks block payments to unlicensed operators), the lottery winnings (the Nationale Loterij / Loterie Nationale winnings are tax-exempt for the player — the National Lottery pays a 35% tax on its gross revenue to the Belgian state, which includes the players' tax), the professional poker (poker players who play regularly and systematically — the "professionele pokerspeler" / "joueur de poker professionnel" — are treated as self-employed professionals and taxed at the progressive rates on net winnings; recreational poker players are exempt).

Belgium has a liberalised gambling market with strict regulation — casual players are not taxed on winnings, but professional gamblers are. All amounts in Euros (EUR). For related reading, see our Personal Tax Guide →, Crypto Tax Guide →, and Starting a Business Guide →.

Tax Exemption for Casual Gamblers

  • The general rule: Occasional gambling winnings are not subject to Belgian personal income tax. The exemption applies to: (a) lottery winnings (Lotto, EuroMillions — the Nationale Loterij / Loterie Nationale), (b) casino winnings (slot machines, table games), (c) sports betting winnings (Soccer 6, sports betting with licensed operators), (d) poker winnings in a casino or poker club, (e) bingo and keno winnings, (f) online gambling winnings with a licensed Belgian operator. The exemption is based on Article 90 of the Belgian Income Tax Code (WIB/92 — "diverse inkomsten" / "revenus divers") — gambling winnings are not listed as taxable income unless they are professional income. The tax authorities take the view that occasional gambling is a "niet-beroepsmatige verrichting" / "opération non professionnelle" — an occasional, non-professional transaction.
  • The "occasional" test: The tax authorities consider several factors to distinguish between casual and professional gambling: (a) the frequency of play (daily or weekly play may indicate professional activity), (b) the amount of winnings (very large, regular winnings are more likely to be scrutinised), (c) the taxpayer's main source of income (if gambling is the sole or primary source of income, it is likely professional), (d) the systematic approach (the use of statistical models, betting strategies, or arbitrage systems), (e) the sponsorship or advertising (sponsored players are professional). The burden of proof is on the tax authorities to demonstrate that the gambling is professional.

Professional Gambling Tax

  • Taxation as professional income: If gambling is the taxpayer's main professional activity (the "beroepsmatig" / "professionnel" gambling), the winnings are taxed as professional income at the progressive personal income tax rates (25–50%). The net winnings (gross winnings minus the documented losses, the stake costs, the travel costs, and the professional expenses) are taxable. The taxpayer must: (a) register as a self-employed professional (zelfstandige / indépendant) with the KBO / BCE, (b) register for VAT if applicable (gambling services are generally VAT-exempt, but ancillary services may be subject to VAT), (c) file a professional income tax return reporting the gambling winnings as "beroepsinkomsten" / "revenus professionnels", (d) pay the self-employed social security contributions (approximately 20.5% on income up to €73,000 and 14.2% above).
  • Loss deduction: Professional gamblers can deduct their losses against their winnings. The losses must be documented (the "verliesbewijs" / "preuve de perte" — the casino statements, the online account statements, the bank records). The losses can be carried forward to future years if they exceed the winnings in a given year (the "verliesoverdracht" / "report de pertes" — the losses can be carried forward indefinitely for professional income).

Licensing and Operator Taxes

  • Land-based casino tax: Belgian land-based casinos are subject to a specific gambling tax (the "belasting op de spelen" / "taxe sur les jeux") on the gross gaming revenue (GGR): (a) 5% on table games (roulette, blackjack, poker), (b) 15% on slot machines. In addition, the casino pays: (a) the standard corporate income tax (25%) on its net profit, (b) the municipal surcharge on the gambling tax (typically 20–30%). The total tax burden on land-based casinos can reach 40–50% of GGR.
  • Online gambling tax (11%): Licensed online gambling operators (licensed by the Belgian Gaming Commission — the Kansspelcommissie / Commission des Jeux de Hasard) are subject to 11% tax on gross gaming revenue (the "online belasting" / "taxe en ligne"). The online gambling licence (type A, A+, A++, F1, F2) costs approximately €25,000–€75,000 per year, depending on the licence category. The operator must also contribute to the EPIS system (the Excluded Persons Information System) and implement the KYC/AML requirements under the Belgian Anti-Money Laundering Law.
