Is forex trading tax free in the UK?

Forex profits are free of Capital Gains Tax and Income Tax when you trade as a private individual using a spread betting account. With a spread bet, you wager on whether a currency price rises or falls, staking a set amount for each point of movement. The underlying currency itself is never something you buy. HMRC treats this as betting, so its manual says punters pay no tax on the profits and get no relief for their losses.

Lots of beginners get caught out by that rule on losses. Money lost on a forex spread bet can't be set against taxable gains you make on shares or other assets. For how it works in practice, see spread betting tax in the UK.

Foreign currency that you acquire to spend personally outside the UK is also covered by an HMRC exemption. Holiday money is what that exemption is for, not speculative trading activity.

The CFD rules in the UK cover capital gains on forex contracts for difference and on foreign currency trades. A CFD, short for contract for difference, is an agreement you make with a broker. It settles the difference in cash caused by a currency price moving between the opening of a trade and its close. HMRC treats retail CFDs as financial futures, and your net gain is taxed when you close the contract.

Your gain or loss comes from adding up all debits and credits on the closed trade. Broker commission and overnight financing adjustments feed straight into that net figure. Both products track the same currency prices but sit under different tax rules, so comparing spread betting vs CFD accounts matters.

Both spread betting and CFD accounts are on offer at several FCA regulated forex brokers. Among them are ActivTrades, Capital.com, CMC Markets, FxPro, IG, Pepperstone, Spreadex and Vantage. Forex through CFD accounts, with no spread betting option, is what some UK brokers such as eToro and XTB provide.

You pay forex tax in the UK only if the tax year's total chargeable gains go beyond your annual exempt amount. Before you owe Capital Gains Tax, your annual exempt amount is the total profit from taxable assets that you can make in each tax year. For 2026 to 2027, individuals have an allowance of £3,000 and most trusts have £1,500.

Before you apply your £3,000 allowance, deduct any allowable losses made on taxable trades. An allowable loss is a taxable asset loss that has been reported. You subtract it from taxable gains to lower your tax bill. Individuals pay 18% or 24% on gains above their allowance, starting 6 April 2026. Which rate you pay comes down to your total taxable income.

Since tax year 2024 to 2025, the individual allowance has remained £3,000, and it was the same in tax years 2025 to 2026 and 2026 to 2027. In 2023 to 2024 it stood at £6,000, and in 2022 to 2023 it was £12,300. Claiming the regime for foreign income and gains, or Overseas Workday Relief, means you won't get the £3,000 allowance.

Even if they trade regularly at home, most retail traders pay no Income Tax on forex profits. In almost every case, HMRC taxes CFD traders' outcomes under Capital Gains Tax, unless your profits are treated as trading income. HMRC says that an organised activity set up to profit from the gambling public normally counts as trading. That point applies to spread bettors. A private punter who places spread bets on their own account doesn't normally carry on a trade. Our day trading tax in the UK guide covers HMRC's approach to frequent trading.
