Are forex trading profits taxable in the UK?
Yes — forex trading profits from a standard trading account are generally taxable as capital gains (using the £3,000 annual exempt amount) or, in rarer cases where HMRC deems the activity a trade, as income. Forex trading conducted via spread betting is different and is generally tax-free, since spread bets are treated as gambling rather than investment transactions.
Full answer
How forex (foreign exchange) trading profits are taxed depends entirely on the type of account and product used. Profits from trading currency pairs through a standard CFD (contract for difference) or direct currency trading account are generally taxed as capital gains, subject to the same "badges of trade" analysis as share trading — for the overwhelming majority of individual retail traders, gains fall under Capital Gains Tax, with the first £3,000 exempt each tax year (2026/27) and the remainder taxed at 18% or 24% depending on your overall Income Tax band. CFDs specifically are also subject to a small Stamp Duty Reserve Tax exemption difference compared with buying underlying shares, but the CGT treatment on profit is broadly the same. If a trader's activity is frequent, leveraged, financed by borrowing and treated as a full-time occupation, HMRC could in principle argue trading income status instead, though this is uncommon in practice for forex retail traders. By contrast, forex trading done through spread betting products is treated by HMRC as a form of gambling under UK law, and gambling winnings are entirely free of both Income Tax and Capital Gains Tax — but correspondingly, spread betting losses cannot be offset against other income or gains either. Traders using leveraged forex products should also be aware that losses on CFD/CGT-basis trading can be offset against other capital gains in the same or future tax years if properly reported, which is not the case for spread betting losses. Use the Capital Gains Tax calculator to estimate liability on non-spread-bet forex profits.
