Understanding your lottery tax
In the UK, all lottery winnings — whether it's the National Lottery, EuroMillions, or scratch cards — are entirely tax-free. But once that money is in your account, several tax considerations come into play.
Interest on your winnings
When your jackpot sits in a savings account earning interest, that interest could be taxable depending on your tax bracket.
Inheritance tax
Your winnings become part of your estate and may be subject to inheritance tax above the £325,000 threshold.
Gift tax implications
Gifting winnings to family could trigger inheritance tax if you die within 7 years (taper relief applies).
