Is spread betting tax-free in the UK?
Detailed explanation
The primary sources are HMRC's own internal manuals, all public on gov.uk: BIM22015 (Business Income Manual — betting and gambling: the professional gambler) establishes that even a systematic, successful bettor is not automatically carrying on a trade; CG56105 (Capital Gains Manual — futures: financial spread betting) states that spread-bet outcomes are outside Capital Gains Tax entirely; and BIM22020 sets the boundary — where spread betting is organised as a business and forms the taxpayer's main source of income, HMRC can assess the profits as trading income.
In practice: a UK employee or self-employed person who spread bets alongside their main income pays no tax on winnings and gets no relief on losses. The tax-free status is a function of the product's legal classification as gambling, which is also why it is only offered by FCA-regulated firms to UK and Irish residents.

Spread betting vs CFDs in the UK: what is the difference?
The main differences are tax and how losses are treated. UK spread betting profits are free of Capital Gains Tax (HMRC treats them as gambling), but spread-bet losses cannot be offset against tax. CFD profits are subject to Capital Gains Tax, yet CFD losses can be offset against other capital gains. Both are FCA-regulated, capped at 30:1 leverage on major FX pairs, with negative balance protection for retail clients.
