The British tax reform has moved well past the argument over GGR percentages. Flutter is preparing to cut up to 1,400 jobs, operators are reworking their cost structures, and more rate hikes for online betting are on the way. But the real question isn't simply how much the state will collect. It's who ultimately foots the bill: shareholders, employees, affiliates, B2B suppliers, or the players themselves.
How is the rise in gambling duty reshaping iGaming economics, and why can the operator's extra costs translate into staff cuts, lower affiliate payouts, and renegotiated supplier contracts? Taking the British reform as our case study, 3S.INFO traces how the tax burden ripples through profitability, CPA and RevShare math, player terms, and competition between brands. The central question: who ultimately pays for the tax increases, and how are money and risk redistributed within the industry?
- The UK has long been the gold standard of iGaming. The overview "How to Drive Traffic to Gambling and Betting in the UK" lays out the basic structure of the UK market: strict oversight, a transparent licensing system, high standards for operators, and a long history of online gambling development. For an affiliate, the UK is a tough GEO, but a goldmine for anyone willing to study it: once you understand the local regulation, licensing, and economics, you'll be far better placed to size up the risks and upside of iGaming markets elsewhere.
Flutter Cuts Staff. The Tax Reform Extends Beyond Financial Statements
On October 20, 2026, Flutter Entertainment announced a restructuring of its UK and Irish operations that could lead to up to 1,400 job cuts. The changes will hit staff in Leeds and Dublin, along with the company's operations in Portugal and Romania.
The company ties the restructuring to the UK gambling tax increases approved in the 2025 budget. The expected cost of carrying it out is $80–90 million. Flutter would rather take the hit now than carry higher costs later. The layoffs are still part of a plan that is working its way through consultation.
This is one of the world's largest gambling groups, with Paddy Power, Betfair, Sky Bet, and FanDuel in its portfolio. If a giant like this is rethinking headcount, smaller operators may have even less room to maneuver.
Flutter is not the only company facing the need to optimize. According to Reuters, Entain has also announced hundreds of job cuts and changes in its customer support division amid the growing tax burden.
Tax policy is no longer just a line item on operator P&Ls. It is quietly redrawing the industry itself: jobs, marketing budgets, affiliate deals, and product investment.
When 19 Percentage Points Turn Into a Problem for the Entire Business Model
In November 2025, the UK government approved a major overhaul of gambling sector taxation.
As of April 1, 2026, the Remote Gaming Duty rate for online casinos rose from 21% to 40%. The next stage is set for April 1, 2027: for most types of online sports betting, the rate will climb from 15% to 25%. Betting on British horse racing keeps its existing tax treatment, and no equivalent increase is planned for land-based bookmaker bets.
The government expects the reform to deliver additional budget revenue: £810 million in the 2026/27 fiscal year, rising to £1.16 billion by 2030/31.
The tax is calculated on a statutory base that is economically close to GGR (Gross Gaming Revenue), the difference between stakes taken and winnings paid out. But GGR is not net profit: the operator still has to cover bonuses, payment infrastructure, gaming platforms, staff, licensing, marketing, and affiliate commissions.
Consider a hypothetical online casino with GGR of £10 million over a given period and operating costs of £7 million, before the tax under discussion.
At a 21% rate, the company pays the state £2.1 million, leaving £900,000 in profit before other taxes.
At a 40% rate, the tax climbs to £4 million. All else being equal, the same business now posts a £1 million loss.
A 19-percentage-point hike doesn't just shrink profit. In this example, it turns a profitable operator into a loss-maker, with no change in its underlying commercial performance.
The calculation is hypothetical and doesn't account for the specifics of a given business's taxable base, but it illustrates the problem well. Once the extra tax swallows the operating margin, the company starts cutting what it can control.
Marketing budgets are among the first to come under review.
Affiliate Marketing: Why the Tax Burden Becomes the Partners' Problem
For affiliates, the British reform sets an ugly precedent. On paper, their tax obligations don't change, but the players they refer become less profitable for the operator, and with that comes a lower willingness to pay the same price for traffic.
Back in November 2025, Flutter estimated the potential negative impact of the tax changes on adjusted EBITDA at $320 million in 2026 and $540 million in 2027, before offsetting measures. Among the offsets it cited were cuts to operating, bonus, and marketing spend.
In February 2026, iGB Affiliate ran a column by Joshua Gamble, managing director of ActiveWin, who anticipated a review of CPA rates, tougher traffic quality requirements, and a reduction in the number of partners regulated operators work with.
In a piece for iGaming Affiliates, industry figures reported that in spring 2026 some British brands had cut affiliate budgets by more than a third, paused long-term partnerships, and reduced payouts on the remaining agreements by roughly 30%. These estimates reflect the experience of individual market participants, not industry-wide statistics.
In practice, the fallout depends on the partnership model.
Under a CPA model (Cost Per Acquisition), the operator pays a flat fee for each player who meets the agreed criteria. If the tax lowers the player's expected profitability, the acceptable customer acquisition cost (CAC) has to be recalculated.
But the situation becomes especially sensitive with RevShare, where the affiliate's income depends directly on the financial results of the players they bring in.
Suppose one partner's players generated £100,000 in GGR. The affiliate program deducts gambling duty from that sum, then applies a 35% RevShare.
At a 21% rate, the base comes to £79,000, and the affiliate's commission is £27,650. After the tax rises to 40%, the base shrinks to £60,000, and the commission to £21,000.
The affiliate loses £6,650, or about 24% of their income, even though traffic volume, player behavior, and the RevShare rate all remained unchanged.
In reality, NGR formulas differ: bonuses, payment costs, and administrative fees may be factored in on top. But the example shows why, for an affiliate, what matters isn't just the RevShare percentage but the formula used to calculate the commission.
This is where the main conflict arises.
The affiliate has already invested in SEO, content, paid advertising, or community building. The players have been acquired, the agreed obligations have been met, but the operator is proposing new terms because its economics have changed.
Trying to apply those changes to traffic acquired earlier is where it gets especially contentious.
Revising CPA for future campaigns is one thing. Changing how commissions are calculated on players already acquired is something else entirely.
Whether such a revision is lawful depends on the contract and applicable law. But even if the agreement allows for changes to the terms, the partner must factor in the risk of lower expected income.
As a result, the hardest hit may be small affiliates who depend on a handful of operators. Large partners can redistribute traffic and negotiate individual terms, whereas smaller sites are often left with a choice: accept the new rates or look for other markets.
Fewer Operators, Less Competition for Quality Traffic
A tax increase formally affects licensed operators in the same segment equally. Yet the business consequences differ substantially by scale.
For an international group, the UK may be one of several markets. As margins shrink, the company can reallocate investment, consolidate its technology infrastructure, or shift capital to more profitable GEOs.
A local operator has fewer options. It carries the costs of licensing, compliance, KYC, payment solutions, risk management, and support. Many of these expenses remain obligatory regardless of the tax rate.
The tax may be the same for everyone, but the cost of staying in the market is not.
Smaller companies may cut marketing, drop certain products, move to ready-made platform solutions, or look for buyers. This sets the stage for consolidation, though it doesn't mean independent brands are bound to close en masse.
For affiliates, fewer operators means fewer potential advertisers.
When dozens of brands are competing for quality traffic, an affiliate can compare CPA, RevShare, conversion, and payout reliability. If there are fewer buyers, it becomes easier for the operator to dictate terms, raise FTD qualification thresholds, and turn away smaller traffic sources.
Competition for strong partners won't disappear. But smaller affiliates may find themselves in a situation where they're no longer choosing the best offer, but rather an operator willing to accept their traffic at all.
Product Becomes the Next Line Item to Cut
The fallout from the tax reform may gradually reach the B2B segment as well.
Game platform providers, aggregators, slot studios, CRM vendors, payment services, and analytics companies don't pay the UK Remote Gaming Duty on behalf of their clients. Yet their revenue depends directly on how much operators can invest.
When margins shrink, the attitude toward procurement and development shifts. The operator starts weighing not so much the number of features as their real economic impact.
Do we need in-house development if an equivalent solution can be bought from a platform? Is it worth integrating a new game studio? How much additional revenue does a CRM tool actually bring in? Can we lower the cost of processing payments?
Vendors that can prove their products' effect on an operator's revenue or costs gain an edge over companies whose value lies mainly in expanded functionality.
But a contradiction emerges here.
To offset the tax burden, the operator needs more efficient technology, yet it's precisely investment in that technology that may end up on the chopping block.
A separate question concerns game studios working on a revenue share model. The tax doesn't necessarily reduce their compensation automatically: much depends on the contractual calculation base. Still, operators may push for a revision of commercial rates or redistribute traffic among suppliers.
So a shift in tax policy can reshape the relationship between the operator and its entire technology stack, even if the suppliers themselves aren't gambling duty taxpayers.
The State Raises Taxes, but Who Ends Up Paying?
The UK government has its own rationale for the reform. Online gambling has grown into a major digital business, and the state carries the costs of regulation, prevention, and the fallout from problem gambling.
The authorities justify the Remote Gaming Duty increase by the need to boost budget revenue and account for the risks tied to online casinos and slots. Land-based betting, meanwhile, kept its rates, partly because of higher operating costs and the role betting shops play in employment.
But the extra tax revenue depends not only on the rates set. It also depends on how the behavior of businesses and players shifts.
Office for Budget Responsibility analysis cited by the parliamentary library suggests that over time operators will pass on roughly 90% of the additional tax burden to consumers through price changes and lower payouts. The forecast also factors in a possible drop in demand and a partial migration to unlicensed offerings. That's a projection model, not a confirmed outcome of the reform.
For players, a tax increase can show up as less attractive odds, fewer bonuses, or tighter terms on promotional offers.
At the same time, regulated brands compete not only with one another but also with unlicensed sites that don't necessarily carry comparable tax and regulatory costs.
Here's the tension: the state wants to boost revenue from legal gambling, yet if the regulated segment's terms deteriorate too far, alternative offerings could start to look more appealing to some players.
This doesn't mean any tax hike automatically expands the illegal market. Users' choices are shaped by trust, the safety of their funds, payment convenience, and how effective enforcement is.
Still, when assessing the results of a tax reform, it's important to look not only at budget receipts but also at the resilience of the legal market.
When a Tax Reform Turns Into Market Consolidation
The British situation shows how a shift in tax policy can set off a deeper restructuring of the industry.
First, operators rework their financial models and commercial budgets. Then they cut underperforming lines, consolidate infrastructure, and drop low-margin projects. For some companies, the next stage may be selling the business or exiting a particular GEO.
Large international groups get the chance to acquire the assets and customer bases of competitors that failed to adapt. But the heavy tax burden also makes investment in the whole market less attractive, so consolidation isn't guaranteed.
For investors, this changes how gambling companies are valued.
GGR growth and active user counts are no longer enough to gauge a business's resilience. What matters now is operating margin after tax, the cost of acquiring and retaining customers, dependence on individual GEOs, and a company's ability to stay profitable as regulation shifts.
Rising GGR doesn't necessarily mean a bigger business valuation if the extra revenue comes at the cost of a thinner margin.
This takeaway matters beyond the UK market. International operators, affiliates, and B2B suppliers operate within a shared economic system, so the fallout from a change in tax burden in one major GEO can hit partners in other countries.
The New iGaming Economics: The Fight for Margin
Flutter's move on the possible 1,400 job cuts shows the British tax reform has already jumped from financial forecasts to concrete management decisions.
The next stage, taking the rate for most types of online betting to 25% from April 2027, will force operators to adapt again.
For affiliates, this means scrutinizing NGR formulas, the terms for adjusting commissions, and their dependence on individual brands. For B2B suppliers, it means proving the commercial value of their products. For operators, it means balancing cost-cutting against staying competitive.
Ultimately, the rise in gambling duty changes not only the size of tax payments but also how money and risk are distributed across the industry.
And the key question now isn't how much more the operator will pay, but how much of that cost it can pass on to the rest of the market, and who ends up in the least advantageous position.
