In most cases, no. An individual does not pay Capital Gains Tax on the currency movement inside a foreign currency bank account — an exemption that has applied since 6 April 2012 — nor on currency bought to spend abroad. Tax can still arise where foreign currency is held as an investment, or where a currency gain is built into the sterling calculation on another asset you sell, such as an overseas property or foreign shares.
This is general information, not personal tax guidance — your residence and domicile position changes the detail, so check your own circumstances with a qualified tax adviser or HMRC before acting.
Do you pay Capital Gains Tax on foreign currency gains in the UK?
Whether a foreign currency gain is taxable depends entirely on how you held the currency. UK tax law treats foreign currency in three broad ways.
- Currency in a bank account — no Capital Gains Tax for individuals since 6 April 2012.
- Currency bought for personal spending abroad — exempt, including money spent on a home overseas.
- Currency held as an investment, or a currency movement built into another asset you sell — potentially chargeable, and always calculated in sterling.
Sterling itself is never a chargeable asset. The sections below work through each situation in turn.
Is a foreign currency bank account subject to Capital Gains Tax?
No — not for an individual. Since 6 April 2012, gains and losses on a foreign currency bank account held by an individual, a trustee or a personal representative are neither chargeable nor allowable for Capital Gains Tax. The change was made by the Finance Act 2012 and is set out in HMRC’s Capital Gains Manual.
Before that date the position was different. Taking money out of a foreign currency account — even moving it between accounts — could count as a disposal and create a chargeable gain. That trap was removed for individuals in 2012, so euros or dollars sitting in your account can rise in sterling value without a CGT charge when you convert them.
The exemption covers the currency itself, not the other assets you might buy with it, and companies are treated under a separate regime (covered below). If you keep balances in more than one currency, the same principle applies to each — see our guide to managing several currencies in one place and to funding a foreign currency account from the UK.
Is buying foreign currency for personal use taxable?
No. Currency you acquire for your own or your family’s personal spending outside the UK is not a chargeable asset. HMRC’s guidance is explicit that this includes money spent on providing or maintaining a residence abroad, and the exemption sits in section 269 of the Taxation of Chargeable Gains Act 1992.
So buying euros for a holiday, or converting pounds into euros to cover the running costs of a Spanish home, does not create a Capital Gains Tax charge on the currency — whichever way the rate has moved since you bought it.
When is a foreign currency gain actually taxable?
Two situations bring a currency gain into charge. The first is holding foreign currency as an investment rather than for spending: currency held purely to profit from exchange-rate movements can be a chargeable asset. The second — and the one that catches more people — is when a currency movement is built into the gain on another asset you dispose of.
HMRC requires every capital gain to be computed in sterling. When you buy an overseas asset you translate its cost into pounds at the rate on the day you bought it; when you sell you translate the proceeds at the rate on the day you sold. If the pound has weakened in between, the sterling gain can be larger than any gain in the local currency — and you can show a sterling gain even when the local price did not rise at all.
| Situation | Capital Gains Tax for an individual | Why |
|---|---|---|
| Currency in a foreign currency bank account | Not chargeable | Exempt since 6 April 2012 (Finance Act 2012) |
| Currency bought for personal spending abroad, including a home | Not chargeable | Personal-expenditure exemption, s269 TCGA 1992 |
| Foreign currency held as an investment | Can be chargeable | Currency held to profit from the rate is a chargeable asset |
| Overseas property or foreign shares sold for currency | Gain chargeable, computed in sterling | Cost and proceeds translated to £ at each transaction date |
| A company’s foreign-currency gains | Corporation tax, not CGT | Taxed under the loan-relationship and foreign-exchange rules |
How does the exchange rate affect Capital Gains Tax when you sell an overseas property?
Because the calculation is done in sterling, the exchange rate can create a taxable gain on its own. Here is an illustrative example using round figures.
Suppose you bought a Spanish property for €400,000 when the pound was strong, at an illustrative GBP/EUR rate of 1.25. Your sterling cost is €400,000 ÷ 1.25 = £320,000. Years later you sell for exactly €400,000 — no profit in euros — but the pound has weakened to an illustrative 1.10. Your sterling proceeds are €400,000 ÷ 1.10 = £363,636.
The result is a sterling gain of about £43,636, even though the euro price never moved. That gain is potentially chargeable to Capital Gains Tax, after your annual exempt amount and at the rate that applies to you.
Now compare the same €400,000 held in a euro bank account over the same period. Its sterling value also rises by about £43,636 — but that gain is not chargeable, because of the 2012 exemption. Same currency move, opposite tax outcome, decided entirely by how the money was held.
The same sterling-based calculation applies to selling a property abroad and to selling foreign shares or ETFs. Note that the rate you use to report a gain is a separate question from the rate you convert at — see which exchange rate to use on your tax return.
How are foreign currency gains taxed for companies?
Companies do not use the Capital Gains Tax rules for most currency movements. Foreign exchange gains and losses on money held, owed or lent are dealt with under the loan-relationship and foreign-exchange rules and taxed as income for corporation tax, following the company’s accounts. That is a different regime from the one that applies to individuals.
If your business carries foreign-currency balances or invoices in another currency, the interaction between the accounting treatment and the tax charge is worth checking with an accountant.
Common mistakes people make with currency and tax
- Assuming a foreign currency account is still taxable. The pre-2012 rules are widely quoted online but no longer apply to individuals.
- Forgetting the sterling calculation on overseas assets. A flat local price can still produce a taxable sterling gain if the pound has fallen.
- Using the wrong exchange rate to report a gain. The rate you got on your transfer is not necessarily the rate HMRC expects on the return.
- Confusing the tax question with the transfer question. Managing the rate you convert at is separate from what you owe HMRC.
- Overlooking residence and domicile. Foreign gains can be taxed differently depending on your status, so the general rule is a starting point, not the whole answer.
How a specialist currency broker helps
A broker does not change your tax position — that is a matter for HMRC and your accountant. What a specialist manages is the part you can control: the rate you convert at, and the timing and certainty of the transfer itself.
Fixing a rate in advance with a forward contract, for example, lets you know the sterling figure before you complete a sale or a purchase, which also makes the eventual tax calculation easier to plan around. You can check the live mid-market rate first as a benchmark.
Cambridge Currencies is a UK specialist currency broker handling transfers from £25,000 to £5m and above. Client funds are safeguarded through its FCA-authorised partners, Currencycloud and ScioPay, and every transaction is completed by phone with a dedicated specialist rather than through an app.
Frequently asked questions
Do I pay Capital Gains Tax when I convert euros back to pounds?
Not on the currency itself if it was held in a bank account or bought for personal spending. The exemption in place since 6 April 2012 means the gain on a foreign currency account is not chargeable for individuals.
Is there tax on exchange-rate profit?
Only in specific cases: currency held as an investment, or a currency movement built into the gain on another asset you sell. Everyday personal currency is exempt.
Do I pay tax on money transferred from abroad into the UK?
Moving your own money into the UK is not itself a taxable event, although the underlying income or gain that produced it may be taxable depending on your circumstances.
How is Capital Gains Tax calculated on an overseas property?
In sterling. You translate the purchase cost and the sale proceeds into pounds at the rates on those dates, so the exchange rate affects the taxable gain — as our guide to Capital Gains Tax and currency on an overseas property sale explains.
Are foreign currency gains taxed differently for non-domiciled residents?
They can be. Residence and domicile affect how foreign gains are taxed, so confirm your status with a qualified tax adviser rather than relying on the general rule.
What exchange rate should I use to report a gain to HMRC?
HMRC accepts a consistent, reasonable rate rather than one compulsory figure, and the rate you transferred at is not always the one to use. See which exchange rate to use for foreign income and gains.
