Capital Gains Tax on Gold: The Sovereign Loophole
This is where most UK gold investors get it wrong — and where the biggest tax savings sit.
The rule: When you sell gold at a profit, you owe Capital Gains Tax on the gain above your annual allowance of £3,000 (2026/27). The rate is 18% if you're a basic-rate taxpayer, 24% if you're a higher or additional-rate taxpayer.
The loophole: UK legal tender gold coins — specifically Gold Sovereigns and Gold Britannias — are exempt from CGT. They're legally currency. HMRC treats them the same way it treats the pound coins in your pocket. Sell a Britannia for a £10,000 profit and you report nothing.
Everything else is taxable: Gold bars, Krugerrands, American Eagles, gold ETFs, gold futures, and digital gold platforms. These are all "chargeable assets" for CGT purposes.
The annual exempt amount of £3,000 provides some shelter. You can realise £3,000 of gains each tax year completely tax-free. A married couple or civil partners can transfer assets between each other without triggering CGT — effectively doubling the annual allowance to £6,000.
The CGT calculation example: You buy a 1kg gold bar for £50,000 and sell it for £65,000. Your gain is £15,000. Subtract the £3,000 allowance: £12,000 taxable. As a higher-rate taxpayer, you pay 24% — £2,880. As a basic-rate taxpayer, you'd pay 18% — £2,160.
The same gain on Britannias? Zero.
