Gold bars or gold coins? How to choose
It's the question almost every first-time gold buyer gets stuck on. Both are physical gold, both are bought the same way, and both go up and down with the same spot price. So why choose one over the other, and does it actually matter?
It does, and the difference comes down to two things: how much gold you get for your money, and how much tax you might pay when you sell. Get those two straight and the decision makes itself.
The short version
Bars give you the most gold per pound. They're the cheapest way to own gold, full stop.
Coins can save you more than they cost, because certain UK coins are free of Capital Gains Tax, and on a sizeable holding that saving can dwarf the small extra you pay upfront.
That's the whole trade-off. The rest of this page is just detail.
Why bars are cheaper
Every gold product costs a little more than the raw metal inside it. That gap is the premium, and it covers refining, minting, packaging and the dealer's margin. Bars are simpler and cheaper to produce than coins, especially in larger sizes, so they carry the lowest premium. Pound for pound, a bar puts more actual gold in your safe than a coin does.
If your only goal is maximum metal for your money, and tax isn't a concern for you, bars win. That's why they're our default comparison.
Why coins can win anyway: Capital Gains Tax
Here's the part dealers rarely explain clearly.
When you sell gold at a profit, the gain can be subject to Capital Gains Tax (CGT). For the 2026/27 tax year you can make £3,000 of gains tax-free (your Annual Exempt Amount); above that, gains are taxed at 18% if you're a basic-rate taxpayer or 24% if you're a higher or additional-rate taxpayer.
That applies to gold bars and to foreign coins like the Krugerrand or Maple Leaf.
It does not apply to UK coins that are legal tender, most importantly the Gold Britannia and the Gold Sovereign. Because they're official UK currency, any gain on them is completely free of CGT, no matter how large.
An illustration (rounded, and everyone's situation differs): say you put £50,000 into gold and years later it's worth £70,000, a £20,000 gain. Held as bars, a higher-rate taxpayer would owe roughly £4,080 in CGT on that gain (£20,000 minus the £3,000 allowance, taxed at 24%). Held as Britannias or Sovereigns, the CGT bill is zero. The extra premium you'd have paid to buy coins instead of bars is usually only a percentage point or two, perhaps a few hundred pounds on a purchase that size. Paying a little more upfront to save several thousand later is, for many buyers, an easy call.
The larger your holding, the bigger the potential gain, and the higher your tax rate, the more that CGT-free status is worth.
What about VAT?
Good news: for gold it isn't a deciding factor. Investment-grade gold, both bars and recognised investment coins, is exempt from VAT in the UK. So you won't pay 20% VAT on either. (VAT does bite hard on silver, which is a separate story for when we add silver to the site.)
So which should you choose?
Lean towards bars if you:
- want the most gold for your money, plainly and simply
- are investing an amount where any future gain is likely to stay within the £3,000 annual CGT allowance
- will hold inside a tax-sheltered structure, or expect tax not to be an issue for you
Lean towards UK coins (Britannia or Sovereign) if you:
- are buying a larger amount and expect a meaningful gain over time
- are a higher or additional-rate taxpayer
- want the flexibility to sell a little at a time rather than one whole bar
- simply want to shelter future growth from CGT
Many buyers end up splitting the difference: bars for the bulk of the metal at the lowest cost, plus some CGT-free coins to keep future gains flexible and tax-efficient. There's no single right answer, only the one that fits your amount, your timeframe and your tax position.
