Do you pay tax on competition winnings in the UK?

No, not if you enter as a private individual. HMRC's guidance treats prizes won by ordinary members of the public, rather than in the course of a business, as outside income tax, and the law says winnings are not chargeable gains, so capital gains tax does not apply either. The full amount reaches you with nothing deducted: win £10,000 and £10,000 is what arrives. Tax only comes into it with what you do next. Interest the money earns can be taxable, and giving a large sum away can bring inheritance tax into play.
Why winnings are not taxed as income
Income tax is a tax on what you earn: wages, self-employment profits, a pension, rent from a property. A competition prize is none of those things. You didn't earn it, you won it, and a one-off windfall sits outside income tax altogether.
HMRC's own guidance on prizes makes the same distinction. People who take part as ordinary consumers are not taxable on the prizes they win. The position is different for someone who wins in the course of their work, such as a self-employed sales agent winning an incentive prize.
Capital gains tax doesn't apply either. That tax is triggered by selling an asset at a profit, and winning a prize involves no sale; the capital gains legislation also declares that winnings from games with prizes are not chargeable gains (section 51 of the Taxation of Chargeable Gains Act 1992). So the money arrives whole. No tax form attached, nothing held back, and the figure on the competition page is the figure that reaches your account.
What can still be taxed
The prize itself is clean. It's what the money does next that HMRC takes an interest in:
- Interest. Savings interest is tax-free up to your Personal Savings Allowance: £1,000 a year for basic-rate taxpayers, £500 for higher-rate and nothing for additional-rate. Interest above that is taxed. The prize was tax-free; the interest is just interest.
- Investment growth. Put it into an investment that rises in value and capital gains tax can apply to the gain. The tax lands on the growth, never on the prize.
- Gifts. Give a large sum away and inheritance tax can apply to the gift if you die within seven years of making it.
The catch worth checking first
A prize can't be taxed, but it can still cost you. Means-tested benefits look at how much capital you hold, and a lump sum can push you over a limit. Universal Credit and Housing Benefit generally aren't available once your savings pass £16,000, and Pension Credit counts every £500 over £10,000 as £1 a week of income. So a payment can shrink or stop even though the prize itself was never taxed.
If you claim any means-tested benefit, check the capital rules before you enter, not after you win. We'd rather print the warning here than have anyone find out the hard way.
Why our prizes are cash
Every Grand Draws prize is cash, paid straight into your bank. Tax and admin are part of the reason why. A physical prize has to be valued, delivered, insured and sometimes sold on, and a car you never really wanted is a problem dressed up as a win.
Cash skips all of it. What you see advertised is what you receive, paid by bank transfer. We aim to pay within one working day of verifying the winner.

Common questions
Do I need to declare competition winnings to HMRC?
For a private individual, a one-off prize isn't taxable income, so there's nothing to declare for the prize itself. Any interest or investment growth it later earns is declared in the normal way. If you enter competitions as part of a business, take advice, because the position can differ.
Is a cash prize treated differently from a car or a holiday?
For income tax, no. Both are windfalls. The practical difference is that a non-cash prize has to be valued, delivered and insured, and keeping or selling it can cost you money.
Will winning affect my benefits?
It can. Means-tested benefits take account of your capital, so a lump sum may push you over a limit, such as the £16,000 savings limit for Universal Credit. Check the rules for the specific benefit you claim before you enter.
