Investing in Gold in the UK: Tax Rules on Coins, Bars and ETFs

The UK's Unusual Gold Coin CGT Exemption

Most investments that gain value are subject to Capital Gains Tax when sold at a profit. Gold is a notable exception for one specific category: UK legal tender gold coins.

The exemption exists because HMRC treats currency issued as UK legal tender as exempt from CGT — the same rule that means you don't pay CGT on gains from holding foreign currency for personal spending. Because Gold Britannias and Gold Sovereigns are technically legal tender in the UK (with a nominal face value, even though their market value is far higher, driven by their gold content), they inherit this currency exemption.

This is a genuine, long-standing quirk of UK tax law — not a loophole under threat of imminent closure — and is widely used by UK gold investors specifically for this reason.

VAT Treatment of Gold

Separately from CGT, gold also benefits from a VAT exemption under the Investment Gold Scheme:

• Investment-grade gold — bars and coins meeting a minimum purity (generally 995 thousandths for bars, and coins minted after 1800, of a purity not below 900 thousandths, that are or have been legal tender and are normally sold at a price not exceeding 180% of the gold's open market value) — is exempt from VAT on purchase.
• Non-investment gold — jewellery, gold below the purity threshold, or numismatic/collector coins priced significantly above their gold content — is subject to standard-rate VAT (20%).

This means both Britannias/Sovereigns (VAT-exempt) and most investment-grade gold bars (also VAT-exempt) avoid the 20% VAT hit — the CGT exemption is the differentiator between coins and bars, not VAT.

Gains on Gold Bars and Non-Exempt Coins

Where CGT does apply (bars, foreign coins, jewellery), gold is generally treated as a chattel — a tangible, movable asset — for CGT purposes:

• The annual CGT exempt amount (£3,000 for 2026/27) shelters modest gains before any tax is due.
• Gains above the exempt amount are taxed at 18% (basic rate) or 24% (higher/additional rate) for the 2026/27 tax year, under the "other assets" CGT rates.
• Special chattels rules can reduce the taxable gain on individual items sold for £6,000 or less, though high-value gold bars will typically exceed this threshold.

Gold ETFs and Gold-Backed Funds

For investors who want gold exposure without storing physical metal, gold Exchange Traded Funds (ETFs) or Exchange Traded Commodities (ETCs) are a common route. These are:

• Taxed as securities, not as currency — so the coin CGT exemption does not apply.
• Eligible to be held inside a Stocks and Shares ISA (£20,000 annual allowance for 2026/27) or a SIPP, sheltering any gains and reducing/eliminating tax entirely within the wrapper.
• Generally more liquid and lower-hassle than physical gold — no storage, insurance, or authentication concerns, but you don't hold the physical asset.

Which Route Makes Sense?

For most UK retail investors making meaningful gains, the coin route remains the standout tax-efficient option precisely because there's no CGT to plan around at all — no annual exemption to use up, no rate to calculate, and no reporting requirement on sale (though records should still be kept in case HMRC queries the transaction).

Practical Considerations Beyond Tax

Tax efficiency isn't the only factor:

• Storage and insurance — physical gold (coins or bars) needs secure storage, either at home (with appropriate insurance) or via a bullion dealer's vaulting service (which usually carries a fee).
• Liquidity — coins from reputable mints are generally easy to sell back to bullion dealers at a small spread; large bars can be less liquid for smaller investors.
• Authentication — buying from reputable, established dealers (such as the Royal Mint directly, or established bullion dealers) reduces the risk of counterfeit product.
• No income — unlike shares or bonds, physical gold produces no dividend or interest income while held — the return depends entirely on price appreciation.

Gold is generally considered by financial planners as a diversification or inflation-hedge allocation within a broader portfolio, rather than a primary long-term growth holding — the CGT exemption on coins is a genuine UK-specific tax advantage, but shouldn't be the sole reason to hold a large proportion of a portfolio in a single non-income-producing asset.
