Spain has run a licensed online gambling market since 2011, regulated by the DirecciΓ³n General de OrdenaciΓ³n del Juego (DGOJ). It's a stable, well-established system β the parts worth knowing about are how to actually verify a licence, and a tax rule that catches a lot of players off guard.
DGOJ-licensed operators
Any operator legally targeting Spanish players holds a DGOJ licence β check the operator against the DGOJ's public register before depositing anywhere. Spain, Portugal and France also share a poker liquidity-sharing agreement dating to 2018, which is a quirk specific to how Spanish-licensed poker rooms pool players across borders, though it doesn't extend to casino games.
Gambling winnings and Spanish tax
Unlike the UK or Ireland, Spain doesn't exempt gambling winnings from tax the same way β winnings are generally treated as taxable income (ganancias patrimoniales) for Spanish tax residents and need to be declared, regardless of whether the casino itself is DGOJ-licensed. This is a genuinely different rule to most of Europe, and one that guides written for a UK or Irish audience routinely miss when applied to Spain. This isn't tax advice β if you've had a significant win, it's worth a conversation with a gestor or tax advisor about your specific situation.
Prediction markets, specifically, are being blocked
Separate from casino gambling: Spain opened sanction proceedings against prediction-market platforms like Polymarket and Kalshi in May 2026 and blocked both as a precautionary measure for operating without a gambling licence. This doesn't affect licensed online casinos at all β it's a distinct enforcement action against a different product category β but it's a sign of how actively the DGOJ is currently policing unlicensed operators of any kind.
RGIAJ
Spain runs a national self-exclusion register, RGIAJ, established under Order EHA/3080/2011 β registering blocks you from every DGOJ-licensed operator at once. Every licensed site is also required to display the "Juego Seguro" safer-gambling seal, which links to the DGOJ's official safer-gambling microsite.

Do I have to pay tax on casino winnings in Spain?
Generally yes, if you're a Spanish tax resident β winnings are typically treated as taxable income, unlike some other European countries. Speak to a tax advisor about your specific situation.
How do I check if a casino actually holds a DGOJ licence?
Check the operator against the DGOJ's official public register rather than trusting a badge on the casino's own site.
Does the Polymarket/Kalshi block affect licensed online casinos?
No β that's a separate enforcement action against unlicensed prediction-market platforms, unrelated to DGOJ-licensed casino gambling.
