What Has Changed
As of 1 April 2026, the UK’s Remote Gaming Duty has increased from 21% to 40%. This is the tax that the government charges on profits generated from online casino games, slots, online bingo, and any other gaming activity that takes place over digital channels. It applies to every operator that provides remote gaming services to UK customers, regardless of where the operator is based.
The increase was announced by Chancellor Rachel Reeves in the Autumn Budget 2025, following a consultation that ran from April to July 2025 on the broader tax treatment of remote gambling. The government’s stated rationale is twofold: to raise revenue for public finances and to apply a higher tax burden to the forms of gambling it considers most potentially harmful — namely online casino and slots products, which it notes have lower operating costs than other gambling formats.
This is not a small adjustment. The rate has nearly doubled. It is the most significant change to UK gambling taxation in over a decade, and its effects will ripple across the industry for years.
What Else Changed Alongside It
The Remote Gaming Duty increase is part of a broader package of gambling tax reforms. Two other changes took effect at the same time or are scheduled shortly after.
Bingo Duty has been abolished entirely as of 1 April 2026. The previous 10% duty on bingo profits no longer applies. The government framed this as support for a lower-risk, community-focused form of gambling — and a simplification of the tax system.
A new remote betting rate of 25% within General Betting Duty will take effect from 1 April 2027. This will apply to online sports betting profits, up from the current 15% rate. Notably, remote bets on UK horse racing are excluded from the new rate and will remain at 15%, as will bets placed via self-service betting terminals in licensed premises.
The combined effect of these changes is expected to raise over £1 billion per year in additional tax revenue by 2027.
How This Affects You as a Player
The Remote Gaming Duty is a tax on operators, not on players directly. You will not see a line item on your casino account showing a tax deduction. However, the government itself has acknowledged that it expects operators to pass on up to 90% of the increased costs to consumers through changes to pricing, payouts, and promotional offers.
In practical terms, this means several things are likely to change — some of which are already visible.
Welcome bonuses are shrinking. Industry analysts have projected that casino bonuses could fall from approximately 17% of gross gaming revenue to around 7% as operators cut promotional spending to protect margins. Larger operators with diversified revenue streams will absorb more of the impact, but smaller brands with tighter margins will cut more aggressively.
Wagering requirements and bonus terms may tighten. Even with the UKGC’s new 10x wagering cap in place, operators have other levers: lower maximum bet limits during bonus play, shorter time windows to clear wagering, reduced maximum withdrawal caps on bonus winnings, and more restrictive game eligibility for bonus funds.
Some smaller operators may exit the UK market. At 40% duty on gross gaming profits, plus the costs of UKGC compliance, payment processing, software licensing, and marketing, the margins for smaller white-label casino brands become extremely thin.
Game selection could shift. Operators may steer players toward games with higher house edges to maintain profitability, or reduce the range of lower-margin games available.
The Black Market Concern
The Betting and Gaming Council, the industry trade body, has repeatedly warned that making the regulated market too expensive could push players toward unlicensed offshore operators. These sites pay no UK tax, are not subject to UKGC regulations, offer no fund segregation, and are not covered by GamStop.
The concern is not theoretical. If legal operators are forced to reduce bonuses, tighten terms, and offer less competitive returns to players, unregulated sites that face none of these pressures become more attractive by comparison. The government has acknowledged this risk and allocated an additional £26 million in funding to the Gambling Commission over three years specifically to tackle the illegal market.
At Sister Guide, our position is clear: no amount of bonus generosity justifies playing at an unlicensed site. Your funds have no legal protection, there is no regulatory recourse if something goes wrong, and self-exclusion tools like GamStop do not apply. The regulated market may become less generous after this tax increase, but it remains fundamentally safer.
Our Take
The 40% Remote Gaming Duty is a significant change to the economics of UK online gambling. It will make the regulated market less generous for players, particularly on the promotional side. That is a real downside, and there is no point pretending otherwise.
But it is also worth perspective. The UK market was already one of the most competitive in the world for casino bonuses, and much of that generosity was funded by margins that some operators could barely afford. If the tax increase results in fewer but more sustainable bonus offers, less predatory marketing, and a market dominated by well-capitalised operators who can afford to treat players properly, that is not entirely a bad outcome.
For UK players, the practical advice is straightforward: stick with UKGC-licensed casinos, expect bonus offers to become less generous over the coming months, read the terms more carefully than ever, and remember that the protections that come with regulated gambling — fund segregation, fair gaming audits, GamStop, independent dispute resolution — are worth more than any welcome bonus.
