Cutting RTP to offset rising tax costs: smart business or dangerous gamble?
The UK online gambling market is beginning to feel the heat of the government’s new 40% remote gaming duty, and online casino sites are already making changes designed to soften the financial blow. One of the clearest trends emerging across the sector is the gradual reduction of slot RTPs. You may have noticed that some slot games now offer lower RTP settings than they did a year ago, meaning player balances tend to last for less time during gameplay.
For many operators, the logic is simple. Lowering RTP increases the house edge, allowing casinos to recover some of the revenue lost through higher taxes. Unlike reducing bonuses or introducing extra fees, RTP adjustments can be made quietly in the background without changing how the game looks to players.
But while the strategy may improve margins in the short term, many industry observers believe it could create bigger problems for the regulated market over time.
Why operators are reducing RTP
Most modern online slots are developed with multiple RTP versions. A single title may be available at 96%, 94%, or even 92%, depending on the configuration an operator chooses. That difference might sound small numerically, but the effect on gameplay can really add up. Lower RTP settings generally reduce how long a player’s bankroll lasts and can also impact how frequently bonus features or larger wins appear during a session.
For businesses facing higher tax obligations, however, the maths is difficult to ignore. Increasing the house edge by even a few percentage points across millions of spins can generate substantial additional revenue. The problem is that player behaviour does not always follow spreadsheet logic.
Players may notice more than operators expect
One assumption behind RTP reductions is that many casual players either do not understand RTP percentages or simply do not pay attention to them. Yet industry experts increasingly argue that players often recognise the difference indirectly through gameplay itself.
Sessions may become shorter, and you may notice deposits disappear faster. Bonus rounds feel less frequent than they once did. Even without knowing the technical explanation of what’s going on, players may begin to feel that games offer worse value than before.
There are also concerns that players will not notice the difference for a long time once games start paying out less frequently. Unlike land-based casinos, online users can move between brands almost instantly if they feel they are getting better value elsewhere. With offshore sites still widely available to UK players, operators risk pushing customers towards unregulated alternatives.
Germany’s experience raises concerns
Germany is often used as a warning example in the RTP debate. After the country introduced an online slots turnover tax, many licensed operators reduced RTPs to around 90% to maintain profitability.
Industry estimates cited by Regulus Partners suggest Germany’s regulated slots market fell from around €800 million in 2022 to roughly €470 million by late 2025. What’s more, the black market may have grown to approximately €2 billion.
Critics believe lower RTPs played a major role in driving players away from licensed sites and towards offshore alternatives that offer better value. While the UK market is still in a much stronger position, some analysts warn that the same risks could emerge if operators continue pushing RTPs down.
Some operators are resisting the trend
Not everyone believes lowering RTP is the right response to higher taxes.
A number of operators have signalled their intention to maintain stronger payout models as a competitive advantage, betting that player retention and customer loyalty will ultimately prove more valuable than short-term margin gains.
In an increasingly crowded market, maintaining higher RTPs could become an important way for operators to distinguish themselves from rivals aggressively cutting payouts across their slot portfolios.
At the same time, the financial pressure created by the UK’s new tax structure means many businesses may feel they have little choice but to continue searching for operational efficiencies wherever possible.
Is it a short-term solution with a long-term effect?
Lowering RTP may ease some of the pressure from higher taxes in the short term, but the long-term impact is far less certain. If players start spending less time on licensed sites or move to offshore casinos offering better value, operators could face a much bigger issue than tighter margins.
The debate ultimately comes down to one question: should RTP be treated purely as a revenue tool, or as part of the overall entertainment value that keeps players engaged in the regulated market?
As the UK gambling sector adapts to its new economic reality, the answer may determine whether operators strengthen long-term sustainability or unintentionally repeat mistakes already seen elsewhere in Europe.
