UK Gambling Tax Doubles to 40% – What It Means for Online Casinos

The UK government is nearly doubling the tax on online casino operators. Starting 1 April 2026, Remote Gaming Duty (RGD) rises from 21% to 40% of gross gaming revenue. A second increase follows in April 2027, when General Betting Duty on remote betting goes from 15% to 25%. Combined, these changes will extract over £1 billion per year from the industry.

We tracked this through the Autumn Budget 2025 announcement, the public consultation, and the government's November 2025 response. Here is what it actually means – for operators, for bonuses, and for the players who use our ranked casinos.

The Numbers

The tax overhaul hits two duties:

• Remote Gaming Duty (casino, slots, live dealer, poker, bingo): 21% → 40% from 1 April 2026
• General Betting Duty (remote betting): 15% → 25% from 1 April 2027. Exception: remote bets on UK horse racing stay at 15%, since operators already contribute 10% to the Horserace Betting Levy
• Bingo Duty: 10% → abolished from 1 April 2026

The Treasury projects additional revenue of £810 million in 2026–27, rising to £1.1 billion annually once both increases take full effect.

Land-based duties remain unchanged. General Betting Duty for retail stays at 15%, and Casino Duty holds its tiered structure of 15–50%.

Why This Matters for Operators

Here is the maths. An operator earning £100 million in GGR from UK online casino currently pays £21 million in RGD. From April, that bill jumps to £40 million – a £19 million hit to the bottom line. For operators running on 15–20% profit margins (common in the UK market), the increase wipes out profitability entirely unless they adjust.

The adjustment options are predictable:

1. Tighter bonus terms. Operators absorb less cost per bonus. Expect lower match percentages, shorter expiry windows, and more restricted game contributions. The UKGC's new 10x wagering cap limits one lever – but operators still control match rates, minimum deposits, and eligible games.

2. Reduced marketing spend. UK operators spend heavily on acquisition – TV ads, affiliate deals, free bet promotions. The tax increase makes every new customer more expensive to onboard profitably. Smaller operators will cut marketing first.

3. Market exit. Marginal UK-facing brands may pull out entirely. The UK already saw licensed operator numbers drop 3.7% to 2,179 in 2024–25. The tax hike accelerates consolidation toward bigger players like Bet365, William Hill, and Flutter (Paddy Power, Betfair).

4. Passing costs to players. Lower RTP configurations on slots, wider spreads on betting markets, and reduced cashback or loyalty rewards. Operators cannot directly increase the house edge on licensed games, but they can choose which RTP variants they serve.

The Affiliate Revenue Share Problem

Here is the angle most coverage misses. Many casino operators pay affiliates through GGR-based revenue share – typically 25–45% of the net revenue a referred player generates. When the operator's own take from GGR shrinks by 19 percentage points, the affiliate's share becomes disproportionately expensive.

Let's say an affiliate earns 30% revenue share. Under the old tax:

• GGR: £100
• RGD (21%): −£21
• Net to operator: £79
• Affiliate share (30% of £79): £23.70
• Operator keeps: £55.30

Under the new tax:

• GGR: £100
• RGD (40%): −£40
• Net to operator: £60
• Affiliate share (30% of £60): £18
• Operator keeps: £42

The operator's profit drops from £55.30 to £42 – a 24% reduction. Affiliates take a smaller absolute cut too, but the operator absorbs the larger share of the pain. Expect operators to renegotiate affiliate deals, shift toward CPA (cost-per-acquisition) models, or reduce affiliate programme sizes.

Our commission-free model at ClearCasinos means we have no stake in these negotiations. We evaluate casinos the same way regardless of what operators pay their marketing partners.

What Changes for Players

The honest answer: not much in the short term, more over the next 12–18 months.

Bonuses will get leaner. The UKGC already capped wagering at 10x, which simplified bonus terms. But operators will offset the tax hit by reducing match percentages. A 100% match up to £200 might become 50% up to £100. Free spin packages will shrink.

Smaller operators may disappear. If your preferred casino runs on thin margins and a UK-only player base, it faces real pressure. Larger operators with diversified markets (EU, LATAM, APAC) can subsidise their UK operations. Single-market operators cannot.

Payment processing stays the same. The tax change does not affect how deposits and withdrawals work. Visa, PayPal, Skrill, and Neteller all function identically.

Player winnings remain tax-free. The UK does not tax gambling winnings – that has not changed and shows no sign of changing.

How We Handle This

Our scoring methodology already accounts for licensing costs and regulatory compliance as factors in the Trust & Licensing dimension (25% of the total score). The tax increase does not change how we score casinos directly – it changes the environment those casinos operate in.

We will monitor bonus terms across our reviewed casinos through Q2 and Q3 2026 as operators adjust. If specific casinos cut bonus value significantly, their Bonuses & Fairness scores will reflect that in our next review cycle.

FAQ

Does the UK tax gambling winnings?

No. UK player winnings are completely tax-free – no income tax, no capital gains tax, no reporting requirements. The April 2026 changes only affect operator-side duties, not players.

Will online casino bonuses get worse?

Likely yes, over time. Operators losing 19 percentage points of GGR to tax have fewer resources for promotions. The 10x wagering cap already simplified bonus structures, but match rates and free spin quantities will shrink.

Which operators are most affected?

Mid-tier operators with UK-heavy revenue and thin margins. Major operators like Bet365 and William Hill have global diversification to absorb the hit. Smaller UK-only brands face genuine pressure.

Why did the government raise gambling taxes?

Revenue. The Treasury projects over £1 billion in annual additional income once both duty increases take effect. The consultation framed it as aligning gambling taxation with the sector's growth – UK online GGR reached £7.8 billion in 2024–25, up 13.1% year-on-year.

Does this affect land-based casinos?

No. Land-based General Betting Duty stays at 15% and Casino Duty retains its tiered structure. The increases target remote (online) operations only.
