Quick answer: Competition prize winnings in the UK are not taxable. No income tax, no capital gains tax on the prize itself. HMRC does not treat a competition win as income.
Do you pay tax on competition winnings in the UK?
No. UK HMRC does not classify prize competition winnings as taxable income. Whether you win cash, a car, a holiday, or any other prize through a UK prize competition, you are not required to pay income tax or capital gains tax on the prize itself.
This applies to all prize types and prize values — there is no threshold above which a prize becomes taxable. A £500 cash win and a £100,000 car win are both tax-free to the winner.
Do you pay tax if you win a car in a competition?
No — the car itself is not taxable when you win it. You receive the full prize value with no tax liability at the point of winning.
However, there are two scenarios worth being aware of:
- If you sell the car for a profit later, the profit may be subject to Capital Gains Tax in the normal way, just as it would be if you bought and sold any other high-value asset. But this applies to the sale, not the win.
- If you take the cash alternative, this is also not taxable — HMRC treats it the same as a cash prize win.
Most operators offer a cash alternative below the headline prize value. This is worth factoring in when comparing competitions — our Value Ratio uses the cash alternative value when available, so you are always comparing like-for-like.
Do you pay tax on game show winnings in the UK?
No. Game show and TV quiz prize winnings are also not taxable in the UK. The same rule applies regardless of the source: HMRC does not class prize winnings as income, whether the prize comes from a TV show, a radio competition, an online prize draw, or a direct ticket-based competition.
The only exceptions would be situations where prize winnings form part of a trade or profession — for example, a professional poker player whose winnings constitute business income. For recreational competition entrants, prizes are always tax-free.
Is a prize draw gambling in the UK?
Not necessarily — and understanding why is important for knowing which sites are legal.
Under the Gambling Act 2005, a lottery is defined as a scheme where participants pay to enter a draw that is determined wholly by chance. A lottery requires a gambling licence to operate legally. Most UK prize competition sites are not lotteries — they are legal prize competitions — because they satisfy one of two legal requirements:
- Skill element: the competition requires participants to correctly answer a question or demonstrate knowledge (even a simple question satisfies this requirement in law)
- Free entry route: participants can enter without making any payment, on equivalent terms to paid entrants
Most UK prize draw sites use the free entry route — which is why they all offer free postal entry. Sites that use skill questions (typically a simple maths or general knowledge question at checkout) also qualify. A site that charges for entry, relies purely on chance, and provides no free or skill route is operating illegally.
Every operator in Competition Showroom's directory operates within UK prize competition law.
Why are postal entries free in UK competitions?
As explained above, UK prize competition operators must provide either a skill element or a free entry route to avoid being classified as an illegal lottery. The free postal entry route is the most common method used.
Importantly, free postal entries must be accepted on exactly the same terms as paid entries. An operator cannot give paid entries more chances, better odds, or any advantage over free entries. By law, a stamped envelope entry has an identical chance of winning as a £5 online ticket purchase.
In practice, the entry volume from postal entries is typically very low compared to online ticket sales — so free entries can actually represent better-than-average odds relative to the effort involved. The address for postal entries is always listed in the operator's full terms and conditions.
How do I know if a UK competition site is legitimate?
A legitimate UK prize competition site will:
- Publish clear terms and conditions including a free postal entry route or skill question
- Name a specific prize with a defined value
- Conduct draws in a verifiable way (typically live on social media)
- Have a track record of published, identifiable winners
- Operate a real UK business with a registered address
Competition Showroom only lists and tracks operators who meet these criteria. See our full operator directory — each page includes a legitimacy assessment and live draw data.
Frequently asked questions
If I win a car competition, do I have to pay taxes?
No. The prize itself is not taxable in the UK. You pay no income tax and no capital gains tax on the car when you win it. If you later sell the car at a profit, the profit on the sale may be liable for capital gains tax in the normal way.
What is the approximate retail value of a prize competition car?
The "Approximate Retail Value" (ARV) quoted by operators is the price of the car new. The cash alternative, if offered, is usually lower — often 70–85% of the ARV. Our Value Ratio calculation uses the cash alternative where it is available, since this is the most conservative (and most useful) measure of prize value.
Are instant win competitions taxable in the UK?
No. Instant win prize winnings are treated identically to prize draw winnings by HMRC — not taxable as income, regardless of the amount.
