Nothing on the win, and a rate that changed on the operator
A player in the United Kingdom pays no tax on a gambling win, and has not since 2001. The money the Treasury would otherwise take is collected from the operator, and the rate at which it is collected has moved recently enough to matter.
The short answer, which is genuinely short
A player in the United Kingdom pays no tax on gambling winnings. Not income tax, not capital gains tax, and not at any level of winning, and this has been the position since the then Chancellor abolished the betting duty paid by punters in 2001; the question comes up constantly because the answer sounds too good, and because the equivalent answer in several other countries is different. There is no threshold above which it changes, no declaration to make, and no difference between a casino win, a sports win and a lottery win.
Where the Treasury takes its money instead
The duty moved from the player to the operator. Remote gaming duty is charged on an operator's profits from online casino games played by British customers, general betting duty on its profits from betting, and the operator pays regardless of where it is based, because the charge follows the customer.
That is the whole architecture: one charge, levied once, on the party that is easier to tax and harder to lose track of. A player who hears that "gambling is taxed in Britain" has heard something true about the operator and false about himself.
The rate that changed, and why operators talked about it
Remote gaming duty was introduced at fifteen per cent in 2014 and has been increased since, most recently in a change that the industry lobbied against loudly enough for it to reach the general press; the rate matters to a player only indirectly, and the indirect route is real: a higher duty is a cost, and costs show up in the generosity of promotions and in the return figures of the games offered. Nothing about it changes the position of the player's own tax return, which remains that there is nothing to put on it!
The exceptions that are not exceptions
Two situations get described as exceptions and neither is. The first is the professional gambler, and the position here has been settled for a long time: gambling winnings are not trading income in the United Kingdom, however systematic the gambling, because the courts have consistently held that betting is not a trade. A professional poker player pays no income tax on his winnings and gets no relief for his losses either, which is the other half of the same rule.
The second is interest. Winnings are not taxed, and the interest earned on them once they are in a bank account is ordinary savings income, taxed in the ordinary way. That is a tax on the interest rather than on the win, and it catches people only because the sum arrived from a casino.

What about a win abroad
A British resident winning at a casino abroad is still a British resident, and the United Kingdom still does not tax gambling winnings, so nothing changes at this end. What can change is the other end: some countries withhold tax on casino winnings at source, the United States being the example most readers meet, and the money withheld there is not recoverable through the British system. An online win at an operator licensed in Great Britain raises none of this, because the operator is inside the British duty regime and nothing is withheld from the player at any point.
Questions readers ask
Do I need to declare gambling winnings to HMRC?
No. Gambling winnings are not taxable income in the United Kingdom and there is nothing to declare, at any amount. What is declarable is interest earned on the money once it is in a savings account, which is ordinary savings income.
Does the answer change if I gamble professionally?
No. The courts have consistently held that betting is not a trade, so a professional gambler's winnings are not trading income and are not taxed. The same rule means losses are not deductible against anything, which is the part professionals mind about.
Who pays tax on gambling in Britain, then?
The operator. Remote gaming duty applies to its profits from online casino play by British customers and general betting duty to its profits from betting, and the charge follows the customer rather than the company's address, which is what brought offshore operators into the regime.
What if I win at a casino in another country?
The United Kingdom still does not tax the win. Some countries withhold tax at source, and the United States is the one British players meet most often; money withheld abroad is a matter for that country's system and is not recoverable here.
