1. The quick answer
If you live in the UK and win a prize from a properly run prize competition, you keep 100% of what you win. There is no income tax, no capital gains tax and no national insurance to pay on the prize itself. You don't need to declare it on a Self Assessment return.
This is true whether the prize is cash, a car, a watch, a holiday or the tax-free cash alternative shown on each Ultimate Draws competition page.
2. Why prize winnings are tax-free in the UK
HMRC treats prize competition and lottery winnings as windfalls, not earned income. Windfalls fall outside the scope of income tax because they are not the reward for work, trade or a service you've provided. The same rule is why National Lottery, Premium Bond and most gambling winnings are tax-free for the player in the UK.
The duties on prize competitions are paid by the operator, not the winner - so by the time the prize reaches you, every tax obligation on it has already been settled.
3. Cash vs physical prizes
- Cash prizes - paid directly into your bank account, in full, with no deductions for tax.
- Cash alternatives - if you choose the cash alternative on a car or watch, the same tax-free treatment applies.
- Physical prizes - cars, watches, tech and holidays are delivered without a tax bill. You'll still want to budget for ongoing running costs like insurance, servicing or road tax on a car.
4. What can become taxable later
The prize itself is tax-free, but what you do with it afterwards can create small tax obligations under the normal UK rules:
- Interest on cash held in a savings account counts towards your Personal Savings Allowance and may be taxable above it.
- Investment income - dividends and capital gains from investing your winnings are taxed in the usual way.
- Renting out or selling a prize - rental income is taxable, and selling a high-value asset later may trigger capital gains tax above your annual allowance.
- Inheritance tax - anything left in your estate when you die forms part of your assets for IHT. Lifetime gifts can fall outside IHT under the seven-year rule.
5. Gifting some of your winnings
Giving money to family or friends from your prize is not a taxable event for them - they receive it tax-free. For your own estate planning, large gifts may be considered potentially exempt transfers; if you live for seven years after making the gift, it usually falls outside your estate for inheritance tax purposes.
6. Do I need to tell HMRC?
For the prize itself: no. You do not need to file anything with HMRC or mention the win on Self Assessment. If your winnings start generating taxable income - bank interest above your allowance, dividends, rental income - that income is reported in the usual way through your tax return or PAYE coding.
7. Non-UK residents
If you live outside the UK, you'll still receive your Ultimate Draws prize in full. Tax treatment in your country of residence may be different - we recommend checking with a local tax adviser before you enter if you live abroad.
8. This is general guidance, not advice
This page is a general guide for UK residents based on HMRC rules at the time of writing. It isn't personal tax advice. If you've won a life-changing sum, or your situation is complex (business owner, non-dom, trustee, etc.), speak to a qualified accountant or tax adviser before making big decisions.
