UK gambling tax is climbing sharply — what the Remote Gaming and Betting Duty changes actually mean for your odds

Remote Gaming Duty already jumped from 21% to 40% in April 2026. A new 25% Remote Betting Duty follows in April 2027. The government's own officials expect most of that cost to land on punters through worse odds and thinner promotions — here's the full picture.

Tax policy rarely feels like gambling news, but this one will show up directly in your betting slip: narrower odds, smaller promotions, and fewer of the "money back if it loses" offers that have become standard at UK-licensed operators. The changes stem from the Autumn Budget announced on 26 November 2025, and they land in two separate stages.

Why this matters: Government officials themselves estimate operators will pass up to 90% of the tax increase on to customers. If you bet regularly with UK-licensed operators, this is the policy explaining why odds and promotions may feel worse over the next two years, even though nothing about the games or markets themselves has changed.

Stage one: Remote Gaming Duty, already in force

Remote Gaming Duty — the tax operators pay on online casino-style games (slots, roulette, blackjack and similar) — rose from 21% to 40% from April 2026. That's not a modest adjustment; it's close to doubling the tax rate on every pound of gross gaming revenue an operator earns from online casino products. This part of the change is already live and has been for several months at the time of writing.

Stage two: a new Remote Betting Duty, coming April 2027

The second stage is still ahead. From April 2027, a new Remote Betting Duty of 25% replaces the current 15% general betting duty on online sports betting profit. That's a ten-percentage-point rise on the betting side specifically — separate from, and smaller in relative terms than, the gaming-duty jump, but still a substantial increase on operators' betting margins.

It's worth being precise about the date here: this part hasn't happened yet. Anyone telling you online betting duty is already at 25% is describing April 2027's rate as if it were current — it isn't, as of the time of writing.

What's exempted, and why it matters

Not everything is caught by the increases. Horse racing bets, spread betting, pool betting and self-service betting terminals are all excluded from the new Remote Betting Duty. Horse racing's exemption in particular reflects the sport's long-standing, separately negotiated relationship with UK betting taxation — racing has historically been treated as a special case given the direct funding link between betting turnover and the sport itself via the horserace betting levy. The carve-outs tell you something about where government drew its lines: mass-market online casino and sports betting absorb the biggest increases, while racing and niche formats like pool betting are shielded.

Separately, bingo duty (previously 10%) was abolished entirely, and casino gaming duty bands (the tax bands that apply to physical casino premises, distinct from online Remote Gaming Duty) are frozen through 2026-27 rather than rising. Read together, the package reads as a deliberate redirection of tax burden toward online gambling specifically, while giving land-based bingo a genuine cut and sparing physical casinos from further increases for now.

Who actually pays: the pass-through question

The government's revenue projections tell their own story about who ultimately bears this. Officials expect roughly £4 billion in gambling tax receipts for 2025-26, a 9.8% increase on the prior year, rising to around £5 billion in 2026-27. But in the same breath, government's own estimates acknowledge operators are likely to pass up to 90% of the duty increases on to consumers — through worse odds, reduced payout percentages, or scaled-back promotional spending — rather than absorbing the cost into margins. That pass-through is expected to erode the tax yield by an estimated £500 million by 2029-30, as some betting activity shifts toward unlicensed offshore sites that pay no UK duty at all, or simply shrinks as the product becomes less attractive.

That last point is the quiet tension in this policy: a tax rise designed to raise revenue and, indirectly, to dampen problem gambling by making it more expensive to offer generous promotions, carries a built-in risk of pushing some bettors toward unlicensed operators who offer no UKGC protections at all precisely because they're outside the tax and regulatory system altogether.

What this looks like in practice

A useful way to picture the effect: an operator that previously offered odds close to the true probability of an outcome, and ran regular "money back as a free bet" promotions on major fixtures, has less margin to work with once 40% of their casino revenue and (from 2027) 25% of their betting profit goes to duty rather than to the business. Expect that pressure to show up as slightly wider odds margins built into pricing, fewer or smaller promotional offers, and tighter terms on the offers that remain — not a single dramatic change, but a gradual tightening across the market as operators adjust.

What to watch next

The Remote Gaming Duty increase has had several months to filter through pricing already; if you bet mainly on online casino products, it's worth comparing your usual operator's current promotions against what they were offering in early 2026. The betting-side change is still over a year out, so there's time before Remote Betting Duty actually bites — but operators typically start adjusting pricing and promotional budgets well ahead of a known tax change, not on the effective date itself.
