The “honeymoon phase” of the regulated Dutch online gambling market is officially dead. Once viewed as the most promising jurisdiction in Europe following its opening in 2021, the Netherlands has rapidly transformed into a fiscal nightmare for operators and a minefield for affiliates.
In a move that has been described by industry insiders as “regulatory strangulation,” the Dutch government has announced a sharp increase in administrative fees for gambling licenses, effective April 1, 2026 . This hike comes just months after the implementation of a staggering 37.8% gambling tax (Kansspelbelasting) , the highest rate in the European Union.
The message from The Hague is clear: The state intends to extract maximum revenue from the sector, regardless of the long-term viability of private operators. For the iGaming ecosystem—from the boardroom of huge PLCs to the home offices of CPA affiliates—the consequences are severe. Margins are evaporating, marketing budgets are being slashed, and the door to the black market is being kicked wide open.
This article analyzes the new fee structure, the cumulative impact of the tax regime, and the “trickle-down” disaster facing the affiliate marketing community.
The April 1st Hike: Paying More for Less
According to the latest decree from the Ministry of Justice and Security, the cost of doing business in the Netherlands is about to jump significantly. The Kansspelautoriteit (KSA) , the national regulator, argues that the fee increases are necessary to cover the rising costs of supervision and enforcement.
The New Numbers
Starting April 1, 2026 , the fees for processing license applications will increase by nearly 30%.
New License Application:
Old Price: €48,000New Price: €61,300 Impact: This raises the barrier to entry for new, smaller operators. It effectively ensures that only well-capitalized giants can afford to even apply to enter the market, stifling innovation and competition.
License Modification (Changes):
Old Price: €8,000New Price: €10,200 Impact: Every time an operator needs to change a director, add a game vertical, or adjust their technical setup, the regulator will charge over €10k. This discourages operational agility.
The “Cost Recovery” Logic
The KSA operates on a “polluter pays” principle. The regulator does not receive funding from the general tax pot; it is funded entirely by the industry it regulates. However, operators argue that they are paying premium prices for a service that is actively hostile to them. “We are paying the salary of the executioner,” noted one CEO of a mid-sized casino brand operating in the Netherlands. “We pay the KSA to investigate us, fine us, and ban our advertising. Now they want a 30% raise?”
The 37.8% Elephant in the Room
While the license fee hike is an annoyance (a CAPEX cost), the real killer is the OPEX (Operational Expenditure) crisis caused by the tax rate.
In late 2025, the Dutch coalition government, searching for budget plugs, targeted the gambling sector. They raised the gambling tax from an already high 30.5% to a crushing 37.8% of Gross Gaming Revenue (GGR) .
The Profitability Mathematics
To understand why operators are panicking, we must look at the “Unit Economics” of a Dutch player in 2026.
Let’s say a casino wins €100 from a player (GGR).
Gambling Tax: -€37.80 (goes instantly to the state).KSA Supervision Fee: -€1.50 (Levy).CdC (Resolution Fund): -€0.50.Platform/Game Provider Fees: -€15.00 (Standard royalty).Payment Processing: -€2.00.Affiliate Cost (CPA/RevShare): -€30.00 (Customer Acquisition).
Remaining: €13.20.
From that remaining €13.20, the operator must pay for staff, technology, retention bonuses, compliance officers, and office rent. The Verdict: The margins are razor-thin. For many operators, the Dutch market is now a loss-leader. They are operating at a net loss hoping for future tax relief that may never come.
The Affiliate Crisis: “Trickle-Down Poverty”
The prompt correctly highlights the impact on traffic: “Operators pay more — for partners, this means less money for traffic.”
For the readers of CPAMonstro and the wider affiliate community, the Dutch market is undergoing a painful correction.
A. The End of High CPAs
In 2022-2023, CPAs (Cost Per Acquisition) in the Netherlands were among the highest in the world, often reaching €250 – €400 . With the new tax reality:
Operators cannot afford to pay €300 for a player who generates €13 of margin.
Prediction for Q2 2026: We expect widespread “renegotiations” of affiliate contracts. CPAs will drop to the €120 – €180 range.Budget Cuts: Many Tier-2 operators will simply close their affiliate programs entirely, relying solely on organic SEO and database reactivation to save costs.
B. RevShare is Dead (Or Dying)
Revenue Share deals are calculated on Net Gaming Revenue (NGR) .
Formula: NGR = GGR – Taxes – Bonuses – Admin Fees.Because the Tax deduction has jumped to 37.8%, the NGR pot is significantly smaller.
An affiliate on a “40% RevShare” deal in 2026 is earning significantly less real money than they were on a “30% RevShare” deal in 2023.
C. Compliance Overload
The KSA is not just raising fees; they are intensifying supervision of advertising.
The Ban on Untargeted Ads: Mass media ads (TV, Radio, outdoor billboards) are largely banned.Affiliate Scrutiny: The KSA is actively monitoring affiliate sites for “misleading” content, targeting minors, or promising “guaranteed wins.”The Risk: Affiliates face fines of up to €400,000 for compliance breaches. Is it worth the risk for a reduced CPA? Many are saying “No” and pivoting to LatAm or Tier-2 markets.
The “Waterbed Effect”: The Boom of the Black Market
The inevitable consequence of squeezing the legal market is the expansion of the illegal one. This phenomenon, known in Dutch policy circles as the “Waterbed Effect” (push down here, it goes up there), is already visible.
The “Casino Zonder Cruks” Phenomenon
Cruks is the national self-exclusion register. Every legal operator must check it.
Legal Offer: 37.8% tax means legal casinos offer lower RTP (Return to Player) and fewer bonuses . They can’t afford to give free spins.Illegal Offer: A Curacao-licensed crypto casino pays 0% tax in the Netherlands. They offer 98% RTP , massive Welcome Bonuses (200%), and no Cruks checks.
Player Migration
Dutch players are price-sensitive. When they realize the legal product is “worse” (tighter slots, no bonuses), they Google:
“Casino Zonder Cruks” (Casino without Cruks)“Casino Zonder Vergunning” (Casino without license)
The search volume for these terms has spiked 150% in the last six months. The fee hike on April 1st will force legal operators to cut marketing further. This creates a vacuum. The legal brands disappear from visibility, and the aggressive offshore brands (who don’t pay the €61,300 fee) fill the void on Google and social media.
KSA’s “Tough Love” Approach
Despite the industry’s pleas, the Kansspelautoriteit (KSA) is doubling down on enforcement. Under its chairman, the regulator has adopted a zero-tolerance policy.
New Supervision Priorities for 2026:
Duty of Care (Zorgplicht): The KSA requires operators to intervene immediately if a player shows signs of excessive spending (e.g., playing for more than 6 hours or depositing late at night).
Cost: This requires expensive AI monitoring software and 24/7 human compliance teams.
Black Market Blocking: The KSA is trying to block payments and IP addresses of illegal sites. However, this is a game of whack-a-mole. For every site they block, five new mirrors appear.
The KSA justifies the fee increase by saying they need more staff to fight the illegal market. The irony is that the government’s tax policy is the cause of the illegal market’s growth.
Case Study: The “Small Operator” Exodus
The new fee structure is catastrophic for smaller players. Let’s consider “Casino X,” a hypothetical mid-sized operator with a license.
They have a small market share (1-2%).
They run on thin margins.
Scenario: They want to add a Sportsbook to their Casino offering to cross-sell during the 2026 World Cup.The Cost: To modify their license, they must now pay €10,200 to the KSA. They must also integrate a sportsbook provider (tech cost).The Tax: Any profit they make is taxed at 37.8%.
The Decision: The board of Casino X decides it is not worth it. They might even decide to surrender their Dutch license entirely and focus on Germany or Ontario. Result: The market consolidates. Only the “Big Boys” (BetMGM, Unibet, Toto, Holland Casino) survive. The lack of competition leads to a worse product for the consumer.
Strategic Advice for Affiliates (The Pivot)
For those reading this via CPAMonstro , the “Golden Age” of Dutch traffic is over, but money can still be made if you adapt.
Strategy A: The “Super-Compliant” Brand Ambassador
Partner with the biggest legal brands (the ones who can afford the tax).
Focus on SEO for high-intent keywords.
Accept lower margins but aim for high volume and stability.
Warning: Ensure your content is 100% compliant with KSA rules. One mistake could bankrupt you.
Strategy B: The “Grey” Pivot (High Risk)
Many affiliates are quietly shifting their geo-targeting.
Instead of targeting “Netherlands” specifically, they target Dutch speakers with offshore brands.
Pros: Higher CPAs (€200+), better conversion (easier registration, no Cruks).Cons: Legal risk. If the KSA identifies you, they can fine you personally. Payment providers might block your commissions.
Strategy C: Market Switching
Abandon NL. Move traffic to Belgium , Brazil , or Finland (upcoming legalization). The ROI on Dutch traffic is simply becoming too low compared to the effort required.
Conclusion: The Choking of the Goose
The Dutch government has treated the iGaming industry like a golden goose. In 2021, they invited the goose in. In 2024, they plucked its feathers. In 2026, with the 30% fee hike and 37.8% tax, they are actively choking it.
The logic seems to be short-term revenue extraction at the cost of long-term market health.
For the State: They will see a short-term spike in tax revenue, followed by a decline as players move to the black market.For Operators: A brutal year of consolidation and cost-cutting awaits.For Affiliates: It is time to be ruthless with your metrics. If a Dutch campaign doesn’t yield positive ROI immediately, cut it. The margins no longer exist to support “loss-leading” campaigns.
As April 1 approaches, the Dutch market stands as a warning to other jurisdictions: It is entirely possible to regulate a market to death.
