Europe vs Illegal Gambling: The €20 Billion Tax Loss Crisis

How Big Is the Illegal Gambling Problem in Europe?

The scale is enormous — and consistently underestimated. The European Gaming and Betting Association (EGBA) and H2 Gambling Capital both point to an unlicensed market accounting for roughly 24% to 28% of all online gambling activity across the EU. In some markets, that figure is significantly higher.

The total European online gambling market was worth approximately €29.7 billion in gross gaming revenue in 2023. If a quarter of all activity happens on unlicensed platforms, that is a black market worth between €7 billion and €10 billion in annual GGR — with virtually none of it taxed. European licensed operators typically pay effective tax rates of 15% to 25% on GGR. Apply that to the unlicensed market and the lost annual tax revenue reaches approximately €20 billion per year across all EU member states.

That is not a rounding error. It is a structural failure of regulation that affects every country in Europe.

Why Players Still Choose Illegal Gambling Sites

Players do not choose unlicensed sites out of ignorance. Many do so deliberately, for reasons regulated markets have consistently failed to address.

The biggest driver is better odds. Unlicensed operators pay no tax, which means they offer more competitive returns. In heavily taxed markets like France — where operators pay tax on stakes rather than GGR — the gap between licensed and unlicensed payout rates is wide enough to drive sustained player migration to the black market.

Bonuses are another major factor. Unlicensed sites offer welcome promotions that far exceed what licensed operators can sustainably provide. For new players, the short-term appeal of a no deposit casino bonus from an offshore site often outweighs the long-term risks.

Product restrictions also push players away. Germany’s GlüStV 2021 imposes mandatory spin intervals, maximum stakes, and bans on simultaneous slot play. Many German players simply go offshore to avoid these limits. This consumer migration is not just a tax problem — it is a harm problem. Players on black market sites have no responsible gambling tools available, no spending limits, and no legal recourse if things go wrong.

Which European Countries Are Most Affected?

Germany

Germany is the starkest example of over-regulation driving players to the black market. Research suggests up to 40% of German online gambling activity still occurs on unlicensed platforms — making it one of the highest black market share countries in Western Europe. The GlüStV 2021’s strict product controls are widely cited as the primary cause.

France

France taxes operators on player stakes rather than GGR — one of the highest effective rates in Europe. The Autorité Nationale des Jeux (ANJ) has acknowledged persistently high unlicensed activity, particularly in live casino games online, with millions of French players regularly accessing offshore sites.

Italy

Italy’s ADM is one of Europe’s most active regulators, issuing thousands of domain blocks and payment blocking orders against unlicensed sites. Despite this, the black market remains active — and a widespread illegal gaming machine problem persists in the land-based sector separately.

Netherlands, Sweden, and Beyond

The Netherlands only opened its regulated online market in October 2021. Many Dutch players had already built relationships with offshore operators during years of regulatory delay — and transitioning them back has been slow. Sweden’s channelisation rate has declined since its 2019 relaunch as bonus and marketing restrictions push players to unlicensed .com sites. Poland faces one of the most acute problems in Central Europe, with illegal machines and online black market activity both widespread.

How Europe Is Fighting Back

The most common tool is domain blocking — requiring ISPs to block unlicensed gambling sites at the DNS level. Italy, Greece, and Belgium operate large, regularly updated blocklists. The weakness is that VPNs and mirror sites make blocking relatively easy to circumvent.

Payment blocking goes further, requiring banks and e-wallets to decline transactions with unlicensed operators. France, Italy, and the Netherlands have all implemented this with varying effectiveness. Advertising enforcement is also growing, with regulators targeting social media platforms and affiliate networks that promote illegal gambling to European players.

At the EU level, the core problem is structural. Online gambling was excluded from the EU Services Directive, meaning each member state operates its own licensing regime with no cross-border mutual recognition. An operator licensed in Malta is not automatically permitted to serve players in Germany or France. The European Commission has encouraged voluntary cooperation through the Gambling Expert Group but has stopped short of proposing harmonised EU gambling legislation. Without a common framework, the regulatory fragmentation that enables black market activity will persist.

The €20B Tax Loss: Europe’s Illegal Gambling Data Table

Conclusion

Europe’s illegal gambling crisis is a €20 billion annual tax loss, a consumer protection failure, and a clear signal that the current patchwork of national regulations is not working.

We at Casinoble believe the answer is not simply more enforcement. Domain blocks and payment orders help at the margins — but they do not fix the structural problem. The real solution is better-calibrated regulation that makes licensed gambling competitive enough that players choose it freely, paired with genuine EU-level coordination against the platforms operating outside it. Until Europe finds that balance, the €20 billion tax loss will keep growing — and millions of players will keep gambling without any of the protections that regulated markets are supposed to deliver.
