Dutch Gambling Tax Hike Backfires: Revenue Misses Target

The Netherlands raised its gambling tax to 37.8% expecting a windfall, but a joint monitoring report from the Ministry of Finance and gambling regulator Kansspelautoriteit (KSA) found the 2025 increase brought in roughly 2 million euros of extra revenue against a 108 million euro forecast. The report blames a shrinking taxable market: as rates rose, licensed operator revenue fell, players drifted to unlicensed sites, and channelisation by turnover dropped below 50%. It is a textbook case of a tax rise that overshot the point where higher rates stop producing higher receipts.

The finding matters well beyond the Netherlands. Governments across Europe are leaning on gambling duty to plug budgets, and the Dutch numbers are among the first hard data showing that steep rate hikes can hollow out the very base they tax. For a regulated market once held up as a channelisation success story, the report is a warning that tax policy and consumer-protection rules can pull in opposite directions.

What did the Dutch gambling tax report actually find?

The report found the tax increase failed to deliver its promised revenue because the market it taxes got smaller. The gambling levy rose from 30.5% to 34.2% on 1 January 2025 and again to 37.8% on 1 January 2026. The Ministry of Finance had projected the first step would add about 108 million euros in 2025, yet the monitoring review estimates the actual extra take at only around 2 million euros. For 2026, the forecast of roughly 216 million euros in additional revenue is now expected to come in near 57 million euros.

In the report's own words, quoted by trade outlet iGaming Business, "The objective of the tax increase was not achieved: the additional tax revenues turned out lower than expected because the tax base decreased, possibly partly as a result of the rate increase." The authors caution that several market changes hit at once, making it hard to isolate the tax effect, but the shrinking base is named as the central explanation.

Dutch gambling tax: forecast versus actual

Measure	2025	2026
Headline tax rate	34.2%	37.8%
Forecast extra revenue	About 108 million euros	About 216 million euros
Actual or projected extra revenue	About 2 million euros	About 57 million euros
Previous rate	30.5%	34.2%

Why did higher tax rates raise so little money?

Higher rates raised little because they landed on a market already contracting under new consumer-protection rules. From October 2024 the Netherlands imposed monthly deposit ceilings of 700 euros for players aged 24 and over and 300 euros for those aged 18 to 24. A ban on television and radio sponsorship took effect in July 2024, and a ban on shirt and team sponsorship followed in July 2025. Together these measures cut how much regulated operators could take and how loudly they could market, so the taxable pool was falling before the higher rate applied.

A one-off distortion made 2024 look stronger than it was. Betting activity spiked around UEFA Euro 2024, then normalised, so year-on-year comparisons flattered the baseline the tax was measured against. When the elevated summer of football faded and the new limits bit, the base the 37.8% rate is applied to had shrunk.

What happened to channelisation in the Netherlands?

Channelisation measured by money wagered has fallen below the halfway mark. The KSA reported that channelisation by gross gaming revenue slipped from around 51% at the end of 2024 to roughly 49% in the first half of 2025, meaning unlicensed operators now capture more player spend than the licensed market they were meant to displace. Channelisation measured by the number of active player accounts stayed high at about 94%, a gap that tells the story: most Dutch gamblers still hold a licensed account, but a growing share of their money leaks to sites outside the system.

The KSA put the licensed online market at about 600 million euros in the first half of 2025, with the illegal online market estimated at roughly 617 million euros over the same period. When more money flows through unlicensed channels than licensed ones, every point of tax on the legal market taxes a smaller slice of total play.

How badly are Dutch operators being hit?

State-linked operators are already reporting sharp profit hits. Holland Casino, the state casino operator, faces an estimated profit reduction of about 27 million euros for 2025 rising to about 54 million euros for 2026. Nederlandse Loterij, the state lottery, expects reductions of roughly 16 million euros in 2025 and 34 million euros in 2026. Casino and gaming-hall visits fell about 11% year on year between the first quarters of 2025 and 2026, a decline that feeds straight through to both revenue and the tax it generates.

Licensed online revenue was largely flat, at about 602 million euros in the second half of 2025, with roughly 1.38 million monthly player accounts. The picture is not a collapse in participation but a squeeze on how much each account spends inside the regulated perimeter, exactly the dynamic that erodes a rate-based tax.

What is the KSA doing about the illegal market?

The regulator is escalating enforcement while conceding the current approach is not keeping pace. KSA chairman Michel Groothuizen said the authority would "take on illegal supply in a new and innovative way" through an initiative it calls Project Disconnect, aimed at disrupting the technical and payment infrastructure that unlicensed sites rely on. In 2025 the KSA fined five licensed operators a combined 8.6 million euros and four illegal operators a combined 31.2 million euros, and it logged 2,005 reports of illegal gambling offers, a 34% year-on-year increase.

The regulator's own finances feel the strain too. The KSA reported a budget deficit of about 11.1 million euros for 2025, of which roughly 5.3 million euros stemmed from lower-than-expected gambling tax receipts flowing back to fund its work.

Is this a Laffer curve moment for gambling tax?

The Dutch data is close to a real-world illustration of the point where higher rates stop lifting revenue. The Laffer curve describes how, past a certain threshold, raising a tax rate shrinks the taxed activity enough that total receipts fall rather than rise. The monitoring report stops short of that label, noting multiple simultaneous factors, but the mechanism it describes, higher rates plus a base that contracts partly because of those rates, is the same. For a mobile, digital activity like online gambling, where players can switch to an offshore site in seconds, the responsive base makes the effect sharper than for taxes on fixed assets.

How does the Dutch tax compare with other European markets?

At 37.8% the Netherlands sits toward the higher end of European gambling duty, though rates are hard to compare directly because bases differ. The United Kingdom has been consulting on merging its remote gambling duties and raising the remote rate, a debate our coverage of UK betting firms weighing legal action over new checks has tracked, while Germany recently loosened one lever by raising its online slots stake limit to 5 euros. Europe-wide, licensed operators grouped under the EGBA reported 18 billion euros of gross gaming revenue in 2025, underlining how much taxable value is at stake as governments calibrate rates.

What does the report mean for the wider industry?

The clearest lesson is that tax and consumer-protection policy have to be modelled together, not in isolation. Deposit limits, advertising bans and higher duty each individually shrink regulated revenue, and stacking them compresses the base faster than a static forecast assumes. Operators will point to the numbers as evidence that further rate rises risk pushing more play offshore, weakening both tax receipts and the player protections that only apply inside the licensed market.

For finance ministries elsewhere eyeing gambling as an easy revenue source, the Dutch experience is a caution that headline rates and actual receipts can diverge dramatically when the taxed activity is this portable.

What happens next in the Netherlands?

The monitoring report is likely to feed directly into the next Dutch budget debate and into a broader review of the 2021 online gambling regime. With channelisation by revenue below 50% and the KSA warning about the growing illegal market, pressure is building to pair any future tax decisions with tougher enforcement so the legal market can retain more spend. Whether policymakers pause further rate rises, adjust deposit limits, or double down on enforcement through Project Disconnect will shape both the 2026 revenue outturn and the market's long-term channelisation.

Frequently asked questions

What is the current gambling tax rate in the Netherlands?

The Dutch gambling tax rate is 37.8% as of 1 January 2026. It rose from 30.5% to 34.2% on 1 January 2025 and then to 37.8% a year later.

How much revenue did the Dutch gambling tax increase raise?

The 2025 increase was forecast to add about 108 million euros but is estimated to have added only around 2 million euros, according to the joint Ministry of Finance and KSA monitoring report.

Why did the Dutch gambling tax raise less than expected?

Because the taxable market shrank. Deposit limits, advertising and sponsorship bans, a fading post-Euro 2024 spike, and the rate rise itself cut licensed operator revenue and pushed more play to unlicensed sites.

What is channelisation and why does it matter here?

Channelisation is the share of gambling that flows through licensed operators. In the Netherlands it fell below 50% by revenue in the first half of 2025, meaning more money is wagered on unlicensed sites that pay no Dutch tax and offer no local player protections.

What is Project Disconnect?

Project Disconnect is a KSA initiative, described by chairman Michel Groothuizen, to tackle illegal gambling supply through new enforcement methods targeting the infrastructure unlicensed operators depend on.
