The relationship between tax policy and the health of regulated gambling markets has emerged as a surprisingly complex economic question. Recent research suggests that the conventional wisdom about raising taxes on gaming activity—the assumption that higher duties automatically translate into greater government revenue and stronger regulation—may oversimplify the dynamics at work.
A comprehensive study by professional services firm PwC, released through the UK Betting and Gaming Council, examined Europe’s approach to taxing online betting and gaming across multiple jurisdictions. The findings challenge policymakers to reconsider their assumptions about what drives sustainable gaming ecosystems. Rather than presenting a simple story of more taxes equals more revenue, the analysis reveals patterns that complicate straightforward policy interventions.
The European Regulatory Divide
When surveying Europe’s gaming landscape, a striking pattern becomes visible. Countries with restrictive tax regimes and stringent regulatory frameworks have experienced substantially larger black market gambling sectors. France, for instance, maintains a heavily regulated market, yet unlicensed operators capture approximately 57 percent of total gambling activity. Sweden presents a similar phenomenon, with offshore gambling commanding 35 percent of the market, while the Netherlands faces an even more pronounced challenge, with 37 percent of activity occurring outside regulated channels.
These figures contrast sharply with jurisdictions that have pursued more balanced approaches. Spain and Denmark, which employ moderate tax rates and open licensing systems, maintain channelisation rates of around 89 percent. This means that only about 11 percent of gambling in these countries occurs on unlicensed platforms. The difference is substantial and warrants attention from policymakers grappling with how to structure their gambling duties.
Meanwhile, in the United Kingdom, the figures show an alarming trajectory. The black market’s share of online gambling has expanded from approximately 3.3 percent in 2021 to roughly 5 to 6 percent in 2024. These percentages represent hundreds of millions of pounds flowing into untaxed and unregulated operations, a shift that occurred during the relatively recent past and raises concerns about the direction of current policy proposals.
The Tax Revenue Conundrum
Perhaps most intriguing to tax authorities is what the data reveals about government revenue itself. Contrary to intuition, the PwC report found that between 2019 and 2024, countries with tax rates below 25 percent of gross gaming revenue experienced annual growth in tax receipts of 13 percent. Those with higher tax burdens saw their receipts grow at only 9 percent annually. This discrepancy invites scrutiny into the mechanisms driving these differences.
The explanation centres on how operators respond to elevated tax environments. When faced with steeper duties, gambling companies typically scale back their marketing expenditures, reduce promotional bonuses, and curtail customer acquisition spending. The licensed market becomes less competitive, pricing and odds become less attractive to players, and consequently, gamblers migrate toward unregulated alternatives where restrictions are minimal and entertainment value higher. What regulators perceive as a straightforward tax increase thus initiates a chain of market responses that ultimately undermines the desired revenue outcome.
Global Tax Approaches and Their Consequences
The pattern observed in Europe echoes across other regions with differing circumstances. In Germany, recent experience demonstrates how aggressive regulation can backfire. When the State Treaty on Gambling took effect in 2021, Germany introduced centralised licensing alongside stringent consumer protections including deposit limits, strict identity verification, and considerable stake restrictions. The regulatory framework proved so burdensome that monthly tax revenues fell from approximately €55 million to just €10 million, a decline exceeding 80 percent in some periods. Operators found themselves unable to offer the product features and flexibility that players desired, pushing them toward offshore competitors.
Italy, conversely, illustrates how a more measured approach can yield strong revenue streams. Between January and April 2025, Italy collected approximately €2.3 billion in gaming taxes. The revenue derived primarily from gaming machines and devices, which contributed €1.8 billion alone. This performance reflects decades of a structured concession system and tiered taxation that has allowed the industry to generate substantial public income without experiencing the scale of black market competition seen in higher-tax jurisdictions. Skill games and betting competitions contributed an additional €191 million to the Italian Treasury, demonstrating that properly calibrated taxation can sustain diverse gaming formats.
Belgium presents another instructive case. The country maintains differentiated tax structures across regions, with online gambling taxed at 11 percent of gross margin in most areas and casino games taxed between 33 and 44 percent depending on revenue thresholds. Despite these relatively high rates, Belgium’s well-regulated framework and consistent licensing approach have prevented the degree of market leakage evident elsewhere in Europe.
The Asian Experience
The gambling dynamics in Asia underscore these principles at a different scale. Macau, the region’s dominant gaming centre, operates under a 40 percent effective tax rate on casino gross gaming revenue. Despite this substantial rate, tax collections have grown robustly. From January through August 2025, Macau collected approximately MOP$61.9 billion in gaming taxes, reflecting growth of 5.3 percent year-on-year. The government projects total 2025 gaming tax revenue of MOP$88.56 billion, representing roughly 86 percent of Macau’s total government revenue. This performance suggests that when sufficient demand exists and competing jurisdictions maintain comparably restrictive policies, higher tax rates can sustain healthy revenue generation.
However, Southeast Asia more broadly demonstrates how taxation interacts with regulatory stability. The Philippines, which developed a relatively open licensing regime for online gaming operators, has generated substantial gaming revenues through entities like the Philippine Amusement and Gaming Corporation. Yet regulatory uncertainty, combined with evolving international pressure and enforcement concerns, has made the sector volatile. Countries throughout the region have increasingly recognised that gaming operators, when facing unfavourable policy environments, can relocate to jurisdictions with more accommodating frameworks such as Myanmar, Palau, or Nepal.
Thailand stands at an inflection point. The country has historically prohibited online gambling under its 1935 Gambling Act, yet unlicensed operators serve a substantial shadow market. The Thai government is currently exploring legalisation and regulation of online platforms, viewing controlled access and taxation as preferable to prohibition-driven black markets. This policy pivot reflects the global recognition that attempting to eliminate gambling through regulation alone proves ineffective and often counterproductive.
The Elasticity Question
Underlying these observations lies an economic principle central to taxation design: elasticity of demand. Gaming demand exhibits varying degrees of price sensitivity depending on the format and market. When operators increase the effective cost of play through reduced odds or fewer promotional incentives triggered by higher taxes, some players will exit the market or shift to unlicensed platforms.
Operators in heavily taxed markets face a strategic dilemma. They cannot substantially raise prices without losing volume to both legal alternatives and especially unregulated competitors. Yet reducing their own margins to maintain volume further erodes profitability. This squeeze on margins drives consolidation, reduced investment, lower employment, and ultimately smaller regulated markets. The supposed beneficiary of taxation, the government, finds itself collecting less revenue than a more moderate approach might generate.
The Marketing and Competitiveness Factor
Beyond elasticity calculations lies a practical reality: regulated operators in competitive markets invest heavily in brand development, consumer acquisition, and product innovation. These expenditures require profitability margins that high-tax regimes increasingly erode. When licensing fees, taxation, and regulatory compliance costs consume 40 to 50 percent of gross gaming revenue, as occurs in some jurisdictions, operators lack resources for the marketing and product development that make licensed platforms attractive alternatives to unlicensed sites.
Conversely, operators in more moderately taxed jurisdictions allocate resources to customer experience, promoting responsible gambling measures, and maintaining competitive products. Players who might otherwise drift to unregulated operators find licensed platforms offering superior entertainment, better odds or odds-equivalent through promotional mechanisms, and assurance of fair play and payment security. The investment in competition through marketing thus paradoxically increases the proportion of gambling occurring in regulated markets despite lower tax rates on a per-transaction basis.
Looking Beyond Pure Revenue Collection
The sustainability of a gaming regulatory ecosystem depends on more than tax revenue maximisation. It also encompasses consumer protection, employment, sporting sponsorships, and the prevention of problem gambling. When black markets expand, these collateral benefits evaporate. Unregulated operators have no incentive to fund gambling addiction treatment programmes, to support sporting infrastructure, or to maintain employment standards. Their existence represents pure economic deadweight loss from a societal perspective.
The BGC’s assessment, delivered by chief executive Grainne Hurst, captured this broader concern. She cautioned that the UK, despite maintaining one of Europe’s most rigorous and protective gaming regulatory frameworks, risks replicating the outcomes seen in France and Sweden through excessive taxation and regulation. Without balanced policy, the path leads toward substantial black market gambling that contributes no tax revenue, offers consumers zero player protection, and funds neither sport nor the wider economy.
Structuring Sustainable Taxation
The evidence increasingly suggests that sustainable gaming taxation requires calibration around market elasticity, cross-border competition, and the operational realities facing licensed operators. A jurisdiction cannot unilaterally impose tax rates without considering the competitive environment. If neighbouring countries maintain meaningfully lower rates and accessible licensing, capital and players will migrate accordingly.
This does not mean that higher-tax jurisdictions inevitably fail. Large, insular markets with substantial domestic demand, as seen in parts of Asia and continental Europe, can support higher effective tax rates. However, even these markets face diminishing returns beyond certain thresholds. The UK’s recent evolution, where black market share crept upward despite stable or rising tax rates, suggests that regulatory tightening and taxation are approaching or already at points where further increases generate diminishing and eventually negative returns.
The regulatory environment itself matters as much as tax rates. Deposit limits, stake restrictions, and identity verification requirements, while intended to protect consumers, simultaneously reduce the product appeal compared to unregulated alternatives offering unrestricted access and larger play options. This represents a policy tradeoff that regulators must acknowledge. Consumer protection and market size exist in tension when taken to extremes.
The Case for Moderation and Balance
The weight of recent evidence supports what might be termed a moderate taxation and regulation framework, and a framework that should include cryptocurrency-based gaming platforms. Such an approach prioritises market channelisation—maintaining the largest possible share of gambling within regulated environments—over maximising per-transaction taxation. When a 25 percent tax rate with moderate regulation channels 89 percent of gambling activity into licensed operators and generates 13 percent annual revenue growth, it accomplishes more than a 50 percent rate that channels only 43 percent of activity while revenue stagnates or declines.
Spain and Denmark’s experience, supported by broader findings from across Europe and Asia, demonstrates that operators and consumers, when presented with genuine alternatives, will optimise toward jurisdictions that balance revenue generation with sustainable market conditions. Tax policy therefore represents not merely a lever for immediate revenue extraction but a fundamental structural choice about the gaming market’s long-term viability and social contribution.
This understanding does not invalidate gambling taxation as a policy instrument. Rather, it repositions taxation from a tool for maximising immediate government revenue to a component of integrated regulatory design that accounts for behavioural responses, competitive pressures, and the aim of maintaining robust, transparent, protective, and tax-generating regulated markets.
