In a forcefully worded open letter delivered to the House of Representatives today, the Netherlands’ leading gaming stakeholders issued a stark warning: aggressive tax hikes are cannibalizing the regulated industry and driving players toward the black market. The initiative was led by the Netherlands Online Gambling Association (VNLOK), with immediate support from Holland Casino Group and the Dutch Lottery.
A Remarkable 13 Percent Revenue Decline
The data presented by VNLOK provides a sobering look at the consequences of fiscal overreach. Despite lawmakers raising the gross gambling income tax to 34.2% in January 2025 and again to 37.8% in early 2026, actual tax revenue has plummeted.
The state projected €322 million in revenue for 2025 but is currently on track to receive only €288 million, a €43.5 million shortfall.
The Rise of the Illegal Black Market
Operators argue that these tax burdens crush profit margins and force survival tactics that alienate loyal players. For the first time, illegal online betting volumes have officially exceeded the legal market.
Unregulated sites handled €617 million recently, while the strictly regulated market managed only €600 million. Furthermore, local sports programs have seen a €15 million drop in funding as operators struggle to maintain community contributions.
Demands for Sensible Reform
The stakeholders have demanded that State Secretary Eugène Heijnen fulfill his promise to monitor market effects before the end of Q2 2026. They urge politicians to respect the delicate balance between taxation and player protection to prevent the total destruction of the regulated ecosystem.
