Do You Pay Tax on Competition Winnings in the UK? (No, and Here's What Is)
No. A prize you win as a member of the public in a UK competition isn't normally taxable income, and the win is not a chargeable gain for capital gains tax either. What can cost you money is what happens afterwards: interest on cash, selling the prize, giving it away, and means-tested benefits.

We run prize competitions. We aren't tax advisers, and for a large win you should talk to an accountant before you move the money.
Why people expect a bill
It's a fair worry, because money arrives, HMRC exists, and the two usually meet. Scammers lean on that instinct. A message telling you you've won and asking for "tax" before the prize is released is a standard scam, and how to spot a fake competition covers it properly. No genuine UK operator charges you tax to release a prize.
The opposite mistake costs more. You hear "tax free", stop reading, put £30,000 in a savings account and tell nobody. Then the interest, or the benefits office, catches up with you.
Why the win itself isn't taxed
Gov.uk's Income Tax introduction lists premium bond and National Lottery wins among the things you don't pay tax on. For capital gains, section 51 of the Taxation of Chargeable Gains Act 1992 exempts winnings from lotteries and "games with prizes". HMRC guidance recognises public prize competitions alongside free draws, including tests of skill that require a purchase. Both sit outside capital gains tax.
HMRC's business income manual draws the line at why you got the prize: a prize that rewards work or sales can be taxable, while people "merely purchasing goods for their own use" are not. You bought a ticket.
What is taxable: the whole map
Every figure below was checked against gov.uk on 22 September 2026, and allowances change at Budgets, so check the linked page if you're reading this a year from now.
| What happens | Taxed? | Which tax | The limits | Source |
|---|---|---|---|---|
| You win cash or a prize | No | None | None | Income Tax |
| Your cash winnings earn interest | Above your allowance | Income tax | £1,000 of interest tax free for basic rate, £500 higher rate, £0 additional rate. Up to £5,000 more if your other income is under £17,570 | Tax on savings interest |
| You sell a prize for more than it was worth | Possibly | Capital gains tax | Only possessions sold for £6,000 or more. Your car is exempt. First £3,000 of gains a year is tax free | Personal possessions |
| You give winnings away | Possibly, after your death | Inheritance tax | Gifts within 7 years of death may count. £3,000 a year and £250 small gifts are exempt | Rules on gifts |
| You claim Universal Credit | Payment cut, not taxed | None | Over £6,000 in savings cuts it by £4.35 a month per £250. Over £16,000 and you can't claim | Universal Credit |
| The prize comes through your job | Usually | Income tax as earnings | None | BIM45090 |
Interest: where a cash win starts earning taxable money
Say you win £50,000 and put it in an account paying 4%. That rate is an example, not a quote. You'd earn £2,000 in a year.
As a basic rate taxpayer, the first £1,000 of that is covered by your Personal Savings Allowance. The other £1,000 is taxed at 20%. That's £200. Small, but it arrives as a surprise letter from HMRC, because your bank reports the interest after 5 April and HMRC sends the calculation.
An ISA shelters some of it, since interest inside one is not taxed. The cap is £20,000 across all your ISAs in the 2026 to 2027 tax year, so a £50,000 win leaves £30,000 earning taxable interest until the next tax year comes round.
Selling a prize
Most prizes will never trouble capital gains tax. A car is exempt. So is anything with a predictable life of 50 years or less, which HMRC treats as machinery and says covers clocks and watches. And a possession sold for under £6,000 is outside the rules altogether.
A painting or a piece of jewellery is where it starts to matter. Your starting value is what the prize was worth when you won it. HMRC calls that market value. Win a painting valued at £10,000, sell it for £12,000, and the £2,000 gain sits inside your £3,000 annual allowance. Sell it for £15,000 and £2,000 of the £5,000 gain is taxable. Sell soon after winning, for roughly what it's worth, and there's usually little or no gain to tax.
Giving it away
Gifts only matter for inheritance tax if you die within 7 years of making them. And then only if your estate ends up above the inheritance tax threshold. You can give away £3,000 a year, plus as many £250 gifts to different people as you like, with no effect at all. Gifts to your spouse or civil partner are exempt.
Benefits: check this before you enter
This is where "tax free" misleads people most. A win can leave you worse off even though HMRC never takes a penny, and nobody selling tickets, us included, has much reason to mention it.
Universal Credit counts money, savings and investments. Win £10,000 with nothing else saved and you're £4,000 over the £6,000 line. That is 16 lots of £250, so your payment drops by £69.60 a month for as long as you hold it. Win £20,000 and you're over £16,000, so you cannot claim at all. Zero.
You have to report changes to your savings, investments and how much money you have through your Universal Credit account, as soon as they happen. Deliberately giving the money away to get or increase Universal Credit counts as deprivation of capital. Your claim is then worked out as though you still had it. Paying off a debt is not deprivation. Nor is buying something reasonable in your circumstances. Other means-tested benefits have their own rules, so talk to Citizens Advice before you spend or move anything.
When a prize is taxed: work and business
Forum threads on this question often point out that prizes through your employer are different. They are. A prize your employer gives you, or one you win through your job, is usually taxed as part of your pay. The same goes for prizes a business hands self-employed sales agents.
Winning a public competition you entered with your own money is the other case entirely, and it's the one this post covers. Different rules can apply where a business enters, or where a prize is connected to its trade. That one is a question for an accountant.
Do you need to tell HMRC?
Not about the win. You don't normally need to report it, because it isn't taxable income or a chargeable gain. What happens afterwards can be reportable, and interest is reported by your bank. If you already fill in a Self Assessment return, you include taxable interest there, and a taxable gain from selling a prize gets reported through the capital gains service.
How NetCompetitions handles tax
We open later this year, so these are commitments.
- Cash prizes paid in full, with nothing deducted for fees, transfer costs or anything else
- We never ask a winner to pay tax or a fee to release a prize
- We don't give tax or benefits advice. For a large win, we'll point you to an accountant and to Citizens Advice
You can read how it works in the meantime, and our ten-minute check on any competition site applies to us too. The competition glossary explains cash alternatives, which is where a prize becomes money in the first place.
The bottom line
You don't pay tax on competition winnings in the UK, and nobody legitimate will ever ask you to. Treat "tax free" as the start of the answer. If you're on Universal Credit, check the £6,000 line before you enter anything big, and if you win cash, put it somewhere the interest is covered by your allowance or an ISA. For a win big enough to change your life, pay an accountant for an hour. Cheap insurance.
Frequently asked questions
Do you pay tax on competition winnings in the UK?
No. A prize you win as a member of the public is not normally taxable income, and winnings aren't a chargeable gain for capital gains tax. Tax can apply later, to interest on cash winnings or to a gain if you sell a valuable prize. Prizes that come through your job are the main exception.
Do I need to tell HMRC about competition winnings?
Not about the win itself. Your bank reports any interest your winnings earn, and HMRC sends a calculation if tax is due. If you already file a Self Assessment return, include taxable interest there.
Is interest on prize money taxable?
Yes, above your allowance. Basic rate taxpayers can earn £1,000 of interest a year tax free, higher rate taxpayers £500 and additional rate taxpayers nothing. Interest earned inside an ISA is not taxed, and you can put £20,000 into ISAs in the 2026 to 2027 tax year.
Do competition winnings affect Universal Credit?
Yes, if they take your savings over £6,000. Your payment drops by £4.35 a month for every £250 between £6,000 and £16,000, and above £16,000 you cannot claim. You have to report the change, and giving the money away to get under the limit may not work.
Do you pay tax if you sell a prize you won?
Usually not, and most prizes never come close. Capital gains tax only applies to personal possessions sold for £6,000 or more, and the first £3,000 of gains each year is tax free. Cars are exempt, as is anything with a predictable life of 50 years or less, which HMRC says covers clocks and watches. Your starting value is what the prize was worth when you won it, so selling it for more than that is the case to check.
Is a prize from my employer taxed?
Usually, yes. That's the main exception to the rule. A prize your employer gives you, or one you win because of your job, is normally taxed as part of your pay. A competition you entered as a member of the public with your own money is treated differently, and the prize is not taxed.
