No. If you live in the UK, you do not pay tax on gambling winnings. That covers online casinos, sports bets, bingo, poker, the lottery and anything won in a betting shop or casino, at any amount. You do not declare the winnings to HMRC and the casino does not deduct anything before paying you. The tax is collected from the operator instead.
This page is general information, not tax advice. If a large win, a move abroad or income linked to gambling makes your situation complicated, speak to an accountant or to HMRC.
Why winnings are not taxed
Income tax applies to income from sources such as employment, a trade, property or savings. A bet is none of those. The courts settled the principle a century ago, and HMRC's own manual still quotes the judge in the 1925 case of Graham v Green, a man who made his living backing horses: "There is no tax on a habit."
There is a practical reason as well. If winnings were taxable income, losses would be deductible, and most gamblers lose over time. The Treasury would be handing out relief on a vast scale. Taxing the house is simpler and far more lucrative.
Until 2001 punters did pay a betting tax, added to the stake or taken from the returns in betting shops. It was abolished that year and replaced with a tax on bookmakers' profits, partly to stop betting moving offshore. Players have paid nothing directly since.
What about professional gamblers?
The same rule applies. HMRC's Business Income Manual says that having a system, or being successful enough to live off your betting, does not by itself turn gambling into a taxable trade. You can read the guidance at BIM22017 on gov.uk.
The line is drawn around the gambling, not around the person. Money earned from activities connected to gambling is ordinary taxable income. HMRC's own example is a professional gambler paid appearance fees for television. The same logic applies to selling tips, streaming sponsorship, affiliate commissions, coaching, or a salary for playing poker on someone else's behalf. If you are being paid for a service, that is income. Whether winnings then form part of that trade depends on the facts, and that is the point at which you need an accountant.
The flip side: because winnings are not taxed, losses cannot be set against any other income. There is no such thing as writing off a bad year at the tables.
The tax operators pay instead
Every company offering online casino games to people in the UK pays Remote Gaming Duty on its profits from those players, wherever the company is based. On 1 April 2026 the rate rose from 21% to 40%.
You never see this tax, but you feel it. An operator handing two fifths of its gaming profit to the Treasury has less to spend on everything else, and the first things to tighten are the ones you notice: welcome offers get smaller, loyalty rewards thinner, and some sites choose lower return-to-player settings on slots where the game supplier offers a choice. It is one reason we tell readers to check a slot's RTP in its info screen and not to assume it is the same at every casino. Our slots guide explains how.
Operators pay other duties too, on betting and lotteries, plus corporation tax like any other business. Bingo duty was abolished on the same day the gaming rate went up. None of it is charged to your account as a line item.
Winnings from abroad, and playing abroad
If you are UK resident and win in a casino overseas, the UK still does not tax the win. The other country might. Some jurisdictions withhold tax from larger casino or poker payouts to foreign visitors before the money reaches you, the United States being the best-known example. Whether you can reclaim any of it depends on that country's rules and any treaty with the UK, so ask before a big trip if you are a serious player.
If you move abroad, your new country's rules apply, and several do tax gambling winnings.
A separate point: overseas websites that take UK customers without a Gambling Commission licence are operating illegally. The tax position of the win is the least of your problems with those. We cover the risks on our page about unlicensed casinos.
Where tax and benefits can still catch up with you
The win is tax-free. What you do with it afterwards is treated like any other money.
Interest and investment returns
Put a jackpot in a savings account and the interest is savings income. Depending on your tax band you have an allowance for tax-free interest, and a large balance can blow through it in weeks. Invest the money and dividends and capital gains are taxed in the usual way. An ISA shelters returns up to the annual subscription limit.
Means-tested benefits
Benefits such as Universal Credit look at your capital. Winnings sitting in your account count as capital like any other savings. Savings above a lower threshold reduce the payment, and above an upper threshold they stop it. A win that pushes you over a limit must be reported as a change of circumstances. Current thresholds are on gov.uk. Spending or giving away money in order to stay under a limit can be treated as though you still had it.
Gifts and inheritance
Sharing a win with family is not taxed at the time, but large gifts fall under the normal inheritance tax rules if you die within seven years of making them. If you are in a lottery or betting syndicate, a written agreement made before the win shows that each member's share was theirs from the start and not a gift from whoever collected the prize.
Keeping records anyway
You do not need records for HMRC. You may want them for everyone else.
Banks have to ask where large deposits come from, and so do mortgage lenders, solicitors handling a house purchase, and casinos themselves under anti-money-laundering rules. "I won it" is a perfectly good answer when you can show it. Keep the following for any significant win:
- the withdrawal confirmation email or a screenshot of the transaction in your casino account;
- the bank statement showing the payment arriving from the operator;
- for wins in person, the receipt or cheque stub the venue gives you. Ask for a letter confirming the win if the amount is large.
Licensed casinos keep your full transaction history and must give you access to it, so you can usually download statements later. That is one more practical reason to stick to sites with a British licence: the paper trail exists, and it is in pounds, from a UK-regulated business your bank recognises. Source-of-funds checks are explained in our verification guide.
A regular look at your own deposit and withdrawal history is also worthwhile for a reason that has nothing to do with tax. It is the clearest picture you will get of what gambling costs you over a year. Tax-free winnings are still, for most people most of the time, outweighed by losses. If your statement makes uncomfortable reading, the tools on our safer gambling page are a sensible next step.
Questions people ask
Do I need to declare casino winnings to HMRC?
No. Gambling winnings are not taxable income for players in the UK, so there is nothing to enter on a tax return for the winnings themselves.
Is there a limit on tax-free gambling winnings?
No. The exemption does not depend on the amount. A 50 pound win and a seven-figure jackpot are treated the same way.
Do professional gamblers pay tax in the UK?
Generally not. HMRC's guidance says that betting, even when organised and successful, is not normally a trade. Income from related work, such as appearance fees or paid tipping, is taxable.
Do gambling winnings affect Universal Credit?
They can. Winnings count as capital once they are in your account, and means-tested benefits have capital limits. Report a change in savings if a win takes you over a threshold.
Is interest on my winnings taxable?
Yes, potentially. The win is tax-free but interest or investment returns earned on it afterwards are taxed like any other savings income, subject to your allowances.
