It is one of the most common questions we hear at RAX2 Assets: Should I buy gold coins or gold bars?
On the surface, it seems like a straightforward choice. Both are physical gold. Both hold real, tangible value. But for most UK buyers, the answer is not simply a matter of preference. It comes down to tax.
Understanding the difference between CGT-exempt gold coins and standard gold bullion bars could save you thousands of pounds over the course of your investment. Here is everything you need to know before you buy.
The Tax Difference That Changes Everything
In the UK, Capital Gains Tax (CGT) applies to profits made when you sell an asset. In the 2024/25 tax year, the annual CGT allowance dropped to just £3,000. For gold bar investors, any profit above that figure is taxable at either 18% or 24%, depending on your income tax band.
Gold coins are different. Certain UK gold coins, specifically Gold Britannias and Gold Sovereigns, are classified as British legal tender. Under HMRC rules, legal tender currency is exempt from Capital Gains Tax entirely. That means no CGT, no matter how large the gain.
For a long-term investor, this distinction is significant. Gold has historically been one of the strongest performers during periods of economic uncertainty. If you hold an asset that doubles or triples in value and then sell it, the difference between paying 24% tax and paying nothing is not a small detail. It is the difference between a good investment and a great one.
Which UK Gold Coins Are CGT-Exempt?

Not every gold coin qualifies. To benefit from the CGT exemption, the coin must be British legal tender. The two most widely held options are:
Gold Britannia – Minted by The Royal Mint and recognised worldwide, the Britannia is one of the most liquid and trusted gold coins available. It is produced in a range of weights, including the popular 1oz version, and is fully CGT-exempt for UK investors.
Gold Sovereign – The Sovereign has been produced by The Royal Mint for over two centuries. Smaller in size than the Britannia, it is a versatile choice for investors who prefer to build a position gradually, purchasing coins of a lower individual value over time. It is also CGT-exempt.
Foreign gold coins, including Krugerrands, American Eagles, and Canadian Maple Leafs, do not carry CGT-exempt status in the UK, even though they are popular internationally. It is a common misconception that all gold coins share the same tax treatment.
What About Gold Bars?

Gold bars are not legal tender and therefore do not benefit from CGT exemption. Any profit you make above the annual CGT allowance when selling a gold bar is subject to tax.
That said, bars do have certain advantages worth understanding. They typically carry a lower premium over spot price than coins, meaning you are buying closer to the raw gold value. For institutional buyers, large-scale investors, or those purchasing gold as a pure commodity hedge with no intention of selling in significant quantities, bars remain a valid option.
However, for the majority of private UK investors, the tax advantage offered by CGT-exempt gold coins comfortably outweighs the slightly lower premium of bars. Paying less up front means very little if you hand a substantial portion of your gains back to HMRC on the way out.
VAT on Gold: What You Need to Know
Both investment-grade gold coins and gold bars are exempt from VAT in the UK, provided they meet HMRC’s definition of investment gold. This means gold with a purity of 995 or above for bars, and coins minted after 1800 with a purity of 900 or above that have been or are legal tender.
Gold Britannias and Sovereigns meet these criteria. So from a VAT perspective, coins and bars sit on equal footing. The CGT difference is where coins pull ahead for most buyers.
Liquidity and Flexibility

Coins also hold a practical advantage when it comes to selling. Because individual coins carry a lower value than a large bar, you have far greater flexibility over how and when you sell. If you need to release part of your gold holdings, you can sell one coin or five without having to liquidate your entire position.
A 1kg gold bar, worth well over £80,000 at current prices, is a large, indivisible asset. If your circumstances change and you only need to access a portion of that value, you cannot sell half a bar. Coins give you that granularity.
Britannias and Sovereigns are also among the most widely recognised and traded coins in the world. Dealers, banks, and private buyers know exactly what they are looking at. That broad recognition supports strong resale liquidity, wherever you choose to sell.
Gold Coins vs Gold Bars: A Side-by-Side Summary

CGT status: Gold Britannias and Sovereigns are fully CGT-exempt. Gold bars are subject to CGT on profits above £3,000.
VAT: Both are VAT-exempt when they qualify as investment gold.
Premium over spot: Bars generally carry a lower premium. Coins carry a slightly higher premium, offset by the tax savings on exit.
Flexibility: Coins allow you to sell in smaller increments. Bars are indivisible.
Liquidity: Both are highly liquid. Britannias and Sovereigns benefit from global recognition.
Best suited to: Coins suit most private UK investors. Bars suit large-scale or institutional buyers with specific strategies.
Common Mistakes UK Gold Buyers Make

Buying gold without understanding the CGT implications is the most costly error private investors make. Many buyers focus entirely on the gold price and the premium, without considering what happens when they come to sell. By the time they do, the tax bill can be a significant and unwelcome surprise.
Another common mistake is assuming that all gold coins are CGT-exempt. They are not. Only coins that are, or have been, British legal tender qualify. Always verify before you buy.
Finally, some investors buy gold based purely on price, choosing the cheapest option without considering storage, insurance, liquidity, and exit strategy. Gold is a long-term asset. The full cost of ownership matters, not just the purchase price.
