Do You Pay Tax on Gambling Winnings in the UK? The Rules in 2026

No. Individuals in the United Kingdom do not pay tax on gambling winnings. That covers sports bets, casino games, poker, bingo, the lottery and spread betting, whether the win is £20 or £2 million, and whether you gamble once a year or every day. You do not declare winnings on a self-assessment return, and HM Revenue & Customs does not want to hear about them.

The rest of this guide explains why that is the position, the handful of situations where tax touches gambling money indirectly, and how the government collects its share instead: through duties charged on the operators, which rose sharply in 2026 and rise again in 2027.

Income tax applies to the profits of a trade, and HMRC's long-standing view, set out in its Business Income Manual, is that betting and gambling do not constitute trading. The authority is the 1925 case of Graham v Green, in which the judge described a bet as "merely an irrational agreement" that cannot amount to a trade however often it is repeated. HMRC's guidance states the point directly: the fact that a taxpayer has a system for placing bets, or is successful enough to earn a living from gambling, does not make the activity a trade.

Capital gains tax does not apply either. Section 51 of the Taxation of Chargeable Gains Act 1992 provides that winnings from betting, including pool betting, lotteries and games with prizes, are not chargeable gains.

The flip side is that losses attract no relief. You cannot set gambling losses against other income, and a professional who has a bad year cannot carry it anywhere.

The same rules apply. A professional sports bettor, poker player or trader on betting exchanges pays no tax on gambling profits. HMRC does draw one line: if a professional is paid for something other than gambling, for example appearance fees, sponsorship, coaching or media work, that income is taxable in the normal way. The gambling itself remains outside the tax net.

Spread betting on sport or on financial markets is treated identically: the customer is not carrying on a trade, profits are not taxable and losses are not deductible. HMRC's manual applies the same case law to spread bets explicitly. This is why financial spread betting is marketed as tax-free compared with trading the underlying assets, and why the firms offering it pay duty on their profits instead.

Matched betting, arbitrage and exchange trading all fall within the ordinary rules: the activity is still betting, so the profits are not taxed. Our guide to matched betting covers the practical side.

Until 2001, punters paid betting duty on their stakes or winnings at the counter, at 9% for most of its final years. From 6 October 2001 that was replaced by a 15% General Betting Duty on bookmakers' gross profits, and the customer-facing charge disappeared. Every gambling tax since has been levied on the operator.

The 2026 and 2027 changes were announced at the Budget on 26 November 2025 and enacted in the Finance Act 2026, which received Royal Assent on 18 March 2026. Remote Gaming Duty almost doubled on 1 April 2026. The new 25% rate for remote betting takes effect for bets placed on or after 1 April 2027, with an explicit carve-out: bets made wholly on horse racing taking place in the United Kingdom stay at 15%. A football accumulator placed online will be taxed at 25% from April 2027; a bet on the Cheltenham Gold Cup will not. Bingo Duty was abolished from 1 April 2026.

Duties are charged on operators, not on you, but operators respond to them. The usual adjustments are shorter odds on popular markets, fewer and smaller promotions, lower return-to-player settings on slots, and higher minimum deposits. Some operators have already withdrawn or scaled back casino products in Great Britain since the 40% rate took effect. None of this changes the position of your winnings, which remain tax-free; it changes how much there is to win.

The one practical step worth taking is record-keeping. If you receive a large win, keep the operator's confirmation and withdrawal records. Banks and, in the case of property purchases, solicitors may ask for the source of funds under anti-money-laundering rules, and a clean paper trail answers the question quickly. HMRC itself does not require it.

No. Winnings are not income or gains, so there is nothing to declare.

Yes. Lottery wins are betting winnings under the legislation, and Premium Bond prizes are exempt by statute.

Not on poker winnings. Sponsorship, streaming income and appearance fees are taxable.

No. Because winnings are outside the tax system, so are losses.

No. It is a duty on the bookmaker's profits. You may see its effect in odds and promotions.
