What Remote Gaming Duty Actually Is
Remote Gaming Duty is the UK tax on online gambling revenue. On 1 April 2026, it rose from 21% to 40% of Gross Gaming Revenue. RGD is charged on GGR — the difference between what players stake and what they are paid out. If a casino takes £100 million in slot wagers and pays back £95 million in winnings, the GGR is £5 million, and the RGD is 40% of that: £2 million. Crucially, bonus stakes are included in the GGR calculation under the new regime, which increases the effective tax burden beyond the headline rate change.
When the 40% Rate Took Effect
The tax increase was announced in the Autumn Budget on 26 November 2025 and took effect for accounting periods beginning on or after 1 April 2026. It nearly doubled the rate overnight.
What It Costs UK Operators
The financial impact on UK operators is documented in their public disclosures. Flutter estimates a $320 million EBITDA hit in 2026 rising to $540 million in 2027. <a href="/casinos/ladbrokes">Entain</a> guides to approximately £200 million annualised cost. Evoke — the parent of William Hill and 888casino — expects £125 to £135 million and has entered takeover talks after withdrawing its financial guidance. Rank Group described its £46 million annualised impact as enough to eliminate UK profitability.
How Operators Are Responding
Operators have disclosed several mitigation strategies: cutting marketing spend, rationalising bonus and promotional offers, renegotiating supplier contracts, closing retail shops, and reducing headcount. Evoke announced approximately 200 William Hill shop closures and around 1,500 jobs at risk. Rank Group is cutting above-the-line marketing while protecting performance marketing and customer bonusing.
Why the OBR Expects Lower RTPs
The mechanism most relevant to slot players is RTP adjustment. The Office for Budget Responsibility — the government's independent fiscal forecaster — explicitly modelled that operators will seek to pass through around 90% of the duty increase by raising prices or reducing payouts. The OBR's own revenue forecast for RGD is reduced by roughly one-third to account for this behavioural response. In plain language: the government assumes you will be paid back less.
How an RTP Cut Would Actually Work
How would this work in practice? Every major slot provider now certifies games with multiple RTP tiers. <a href="/providers/pragmatic-play">Pragmatic Play</a> offers three tiers — typically 96.50%, 95.50%, and 94.50%. <a href="/providers/play-n-go">Play'n GO</a> offers five, descending to approximately 84%. <a href="/providers/hacksaw-gaming">Hacksaw</a> and <a href="/providers/push-gaming">Push Gaming</a> certify configurations as low as 85-86%. An operator responding to the tax increase does not need to change any game software. They simply select a lower tier from the provider's menu. The game looks identical. The maths change. The player is not notified.
The UKGC Cannot See This Happening
The UKGC does not publish deployed RTP data. Its quarterly statistics cover GGY, spins, sessions, and session duration, but not payback rates. This means there is no official mechanism to detect whether operators collectively shift to lower tiers after 1 April 2026. The regulator can see that revenue went up or down but cannot distinguish between revenue growth from more players and revenue growth from lower payouts.
What Players Should Watch For
What should players watch for? The first quarter under 40% RGD is April to June 2026. Operator trading updates from Flutter, Entain, and Rank are expected in August 2026. Look for language about margin recovery, customer proposition changes, or game mix optimisation — these are the euphemisms that could signal RTP adjustments. UKGC operator data for that quarter will publish in late 2026. In the meantime, checking in-game RTP panels and comparing them to historical data is the only player-accessible verification method.
How the Industry Is Describing It
The Betting and Gaming Council described the tax increase as a devastating hammer blow. Industry analyst Regulus Partners called the 40% GGR regime — including bonuses — a recipe for a doom loop disaster. Whether that prediction is borne out will become visible in the second half of 2026.
