Tax on gambling winnings UK: zero for you, 40% for casinos
There is no tax due on a win at a UK licensed casino. A win is not classified as income, so there is no tax due and no forms to fill in. The tax sits on the casino side of the counter: online casinos have paid 40% Remote Gaming Duty on their profits since 1 April 2026, and free spins have carried a tax value since 2017. This guide reads HMRC's own manuals and notices to explain who pays what.

The rule: gambling winnings are not taxed in the UK
In the eyes of HMRC, a win at a licensed casino, bookmaker, bingo site or lottery is not income. No tax is due, no form has to be filled in, and there is no amount above which that changes.
That is the case whether the win is £5 from a daily prize wheel or a six-figure jackpot. It is the same for cash, for free-spin winnings once they become cash, and for prizes from a free-to-play game. HMRC's own manual confirms this, as does a court decision from more than 100 years ago.
"The basic position is that betting and gambling, as such, do not constitute trading."
HMRC Business Income Manual, BIM22015
It is straightforward once you look at it from the Treasury's point of view. If wins were classified as income, losses would be classified as expenses, and the country's gamblers lose far more than they win. Taxing the casinos rather than the individual players avoids that problem. So the tax sits with the casino, and the section on the 40% duty below explains how much.
Why HMRC does not tax gamblers: a 1925 horse-racing case
HMRC still references Graham v Green, decided in 1925, when it explains why a punter is not operating a business. The judgement has wider implications, including on the status of a "professional gambler".
Mr Graham made his full living from betting on horses at starting prices. The Revenue considered this a trading activity. Mr Justice Rowlatt considered it not to be trading, and his decision is quoted at length in HMRC's manual:
"There is no tax on a habit. I do not think 'habitual' or even 'systematic' fully describes what is essential in the phrase 'trade, adventure, profession or vocation'."
Rowlatt J in Graham v Green (1925), quoted in HMRC BIM22017
HMRC draws its own conclusion: "having expertise or being systematic ('studying form') is not enough to create a trade of being a 'professional gambler'". Neither skill nor volume makes winnings taxable. Someone who spins the slots every day and happens to be ahead is in the same position as someone who plays once a year.
There is one minor exception, and it is about services rather than bets. HMRC acknowledges that some professional gamblers do trade, "for example, where they receive appearance money for appearing on television programmes". The fee is trading income. Whether their winnings are too "would depend upon the facts". For everyone reading this page, this exception does not apply.
What counts as a gambling win
Everything that arrives in your casino balance and can be withdrawn. The way the bet was placed does not concern HMRC.
Cash from a spin or a table
Withdrawable the moment it lands, and untaxed at any size. A jackpot is treated exactly like a £2 win.
Free-spin winnings
Once the spins have paid out, the winnings are yours and untaxed. Any wagering condition is a matter between you and the casino, not HMRC.
Daily prizes
BetMGM's Golden Wheel pays cash to £100, Sky Vegas's Prize Machine to £1,000 and Monopoly Casino's Free Parking Picks to £750. All of it is untaxed cash.
Free-to-play prizes
A prize from a free game, like LiveScore Vegas's daily free game, is still not income. Nothing was staked, and nothing is owed.
Bonus funds
Not money until the wagering is done. When they convert to cash they are a gambling win like any other, and untaxed.
Jackpots and lotteries
There is no upper limit at which tax starts. The win is capital from the day it arrives, which matters for the rules in the next section.
What can be taxed after a win
The win itself is exempt. What you do with it afterwards is subject to the ordinary tax and benefit rules, and that is where people get caught out.
| Situation | Rule that applies | The numbers |
|---|---|---|
| Saving the win and earning interest | Income tax on interest above the Personal Savings Allowance | £1,000 of interest tax-free for basic-rate taxpayers, £500 at higher rate, £0 at additional rate. Low earners may get a further £5,000 starting rate. |
| Giving some of it away | Inheritance Tax rules on gifts | £3,000 a year exempt, unlimited small gifts of £250 per person, and no tax on any gift if you live seven years after making it. |
| Claiming Universal Credit | The capital limit | Below £6,000 ignored. £4.35 a month deducted for every £250 between £6,000 and £16,000. Above £16,000, no award. |
| Filling in Self Assessment | Nothing to declare | Winnings are not income, so there is no box for them. |
| Being paid to gamble | Trading income | Appearance fees and similar payments are taxed like any business income. The bets themselves usually stay outside. |
The Universal Credit line deserves the emphasis. A large win sitting in a current account is capital in the DWP's rules, which count "cash; money in your bank account" in full. A £20,000 win reported the week it is received ends a claim until the funds fall below £16,000. Not reporting it is a different problem, and a worse one.
The interest rule catches people more quietly. Bank interest on a five-figure balance can pass £1,000 in a year, and the excess above the allowance is taxable even though the win that produced it was not.
The tax the casino pays: Remote Gaming Duty at 40%
Online casino profits are taxed through Remote Gaming Duty. Budget 2025 nearly doubled it and that increase is the number behind every headline about a "tax on gambling".
Remote Gaming Duty rate by date
Charged on an operator's profit from remote gaming with UK players.
Rates from HMRC's guidance on General Betting Duty, Pool Betting Duty and Remote Gaming Duty, and the Budget 2025 policy paper.
The duty is charged on the operator's profit from remote gaming with UK players: stakes received less winnings paid out, calculated over three-month accounting periods and paid within 30 days of each period's end. It is the casino's bill. There is no line for it on your withdrawal.
Why did the government choose casino games for the largest increase?
"The government has targeted the biggest increase in tax on remote gaming (for example online slots and casino games), which is generally considered to have lower operating costs and to be more harmful than other forms of gambling."
HMRC, Gambling duty changes, policy paper, 26 November 2025
The same paper says where the money may come from: "This measure will impact individuals if the duty rate increase is passed on to them through a negative change in betting odds or return to player." For operators, "How they respond will be a matter for these businesses."
Betting and bingo are taxed differently
Online sports betting is subject to General Betting Duty, which is charged at 15% until 1 April 2027, at which point it rises to 25% for remote bets. Betting on UK horse racing keeps the 15% rate. Bingo Duty was abolished from 1 April 2026. Of the ten casinos on this site, seven also run a sportsbook, which means the two sides of those businesses carry different rates.
Free spins are taxed as if you had paid for them
From 1 August 2017 a tax value has been assigned to each free spin the moment it is used. This is the rule that ties the daily prizes on this site to the duty above.
"A freeplay when used, effectively becomes a gaming payment, so you must include the notional value of freeplays in your profits' calculation. The notional value is the full amount the player would have paid but for the offer."
So a 10p free spin is worth a 10p stake to the casino in its duty return. What the spin pays out counts as winnings and is deducted, as with any other prize. This rule was introduced by the Finance Act 2017 and applies to accounting periods on or after 1 August 2017.
There is a twist for prizes. HMRC states that "freeplays given out as prizes do not have a value and therefore cannot be deducted as winnings". A prize wheel offering 20 free spins is therefore handing out something worth nothing for duty purposes, and the casino does not get its deduction until those spins produce cash that can be withdrawn.
What the 40% rate does to your bonuses
Worked through a real offer, the duty on one free spin bundle is not what burdens a promotion. The pressure comes from the whole business paying 40% on its margin, and the policy paper says operators may pass that on through a reduction in return to player.
As a real example, take wager-free 100 spins at a nominal 10p, the shape of the welcome offer at MrQ, NetBet, Coral and BetVictor on our list. HMRC values those spins as £10 of stakes. If that slot returns 96% on average, the spins pay out £9.60, which the casino deducts. Duty is charged on the remaining 40p:
Sixteen pence is not what shaves a promotion. The rest of the account is. Every pound a casino keeps from its slots and tables now carries 40p of duty instead of 21p, so the same bundle of free spins costs more relative to what it earns. Fewer spins, win caps, deposit gates and shorter expiries are the levers available, and the roster already shows all four in use. Our guide to withdrawing free spins winnings records which casino pulls which.
What has not changed is your side. A daily prize that lands as cash is still untaxed cash, and our no wagering casino bonuses list shows which offers hand it over with no strings attached.
Keep records anyway
HMRC will never contact you about a win. Three others might.
- Your bank or mortgage lender. A big win from a casino shows on a statement, and lenders read statements. Our guide on gambling and your credit score explains what they see and what they do not.
- The casino itself. Cash a big win and a source-of-funds check follows, at which point the paperwork behind that win is exactly what they want. Our bank statement requests guide says what each of the ten accepts.
- The DWP, if you claim. Capital over £6,000 has to be reported. Keep the withdrawal confirmation with the date printed on it.
A screenshot of the win, the withdrawal confirmation email and the bank credit are sufficient. Keep the three together in case you need to explain where the money came from.
