Overview
The Ksa (Kansspelautoriteit) is the Dutch gambling regulator. It launched on April 1, 2012, and is based in The Hague.
The Netherlands did not allow online casinos for a long time. The Remote Gambling Act (KOA) took effect in April 2021, and on October 1 of the same year, licensed companies officially began offering online casino and betting. The state casino Holland Casino and the state lottery Nederlandse Loterij also moved online.
History
Key regulations

Decline in channelization rate
According to Ksa analysis, the legal market share (channelization rate) fell from 51% at the end of 2024 to 49% in the first half of 2025. In the same period, legal operator revenue was estimated at €600 million and the illegal market at €617 million, so the illegal market became larger than the legal market.
In the second half of 2025, the monthly average of active accounts was 1.38 million, but loss per player fell and growth in legal revenue stopped. The combination of deposit limits, the advertising ban, and tax increases is analyzed as having pushed some players to unlicensed sites.
Backfire effect of tax increases
The Dutch government raised the gambling tax in both 2025 and 2026. However, according to reports from the Ksa and the Ministry of Finance, the actual increase in tax revenue was much smaller than expected. The Ksa itself ran a budget deficit of €11.1 million in 2025 as gambling tax income fell.
Enforcement
| Item (2025) | Details |
|---|---|
| Illegal gambling reports | 2,005 cases (up 34%) |
| Fines on illegal operators | €31.2 million |
| Sanctions on legal operators | A total of €8.6 million across 5 companies (duty of care violations) |
Through “Project Disconnect,” the Ksa shifted from chasing individual sites to cutting the payment, advertising, and domain infrastructure that helps illegal operators. Since August 2025, paid search ads for illegal sites have disappeared from Google, and illegal “.nl” domains have also been cleaned up.
Rating
Along with Germany and Belgium, the Netherlands is a market where regulation is tightening quickly. Its rules for protecting young players are referenced by other countries, but it has also become a leading example of the argument that “excessive regulation grows the illegal market.”
Location
The Ksa is based in The Hague, the Netherlands.
