Do You Pay Tax on Casino Winnings in the UK? Complete 2026 Guide
UK gambling winnings are completely tax-free for players — but there are important caveats for professionals and crypto winners. We explain exactly what HMRC says about casino, sports betting, and poker winnings.
Gambling winnings are not taxable income in the United Kingdom. HMRC does not consider winnings from casino games, sports betting, poker, bingo, or the National Lottery to be taxable income for UK residents, regardless of the amount won.
The legal basis
Gambling winnings are not subject to Income Tax or Capital Gains Tax in the UK. The statutory basis for this is Section 568 of the Income Tax (Trading and Other Income) Act 2005 — gambling does not constitute a trade for tax purposes in the majority of cases. This means a UK player who wins £1,000,000 on a jackpot slot pays exactly £0 in tax on that win.
The "professional gambler" question
While casual gambling is tax-free, HMRC has the power to tax consistent professional gamblers in rare circumstances. The test is whether gambling activities constitute a "trade" under tax law. Factors considered: consistency and volume of gambling activity, use of a systematic approach or trading strategy, dependence on winnings as a primary income source, and the existence of business infrastructure (staff, offices, formal betting systems).
In practice, HMRC rarely pursues professional gamblers, and UK courts have historically been reluctant to classify gambling as a trade. The most relevant case is Graham v Green [1925], which established that a professional bookmaker's punter was not a trader. Modern practice remains in line with this precedent.
Crypto casino winnings
If you win in cryptocurrency at an online casino, the gambling win itself is tax-free — the same exemption applies. However, if you subsequently hold the cryptocurrency and it increases in value, the increase in value (from the time of winning to the time of sale) may be subject to Capital Gains Tax. The gambling gain itself is exempt; only the crypto appreciation is potentially taxable.
Practical implications
For the vast majority of UK casino players, there are no tax implications to gambling wins. You do not need to declare casino winnings on a Self Assessment tax return. No form needs to be filed. You can withdraw any amount from any UKGC-licensed casino without tax withholding.
