For UK traders, choosing between spread betting and Contract for Difference (CFD) trading significantly impacts tax, costs, and trading strategy. Both instruments let you speculate on price movements across forex, indices, and commodities, but they operate under different rules.
Tax Implications: Spread Betting vs CFDs in the UK
Spread betting in the UK enjoys exemption from capital gains tax (CGT) and stamp duty because it's classified as gambling rather than investing. CFDs, however, face CGT on profits. The advantage with CFDs is that losses offset gains—reducing your overall tax bill. If you profit £10,000 on one CFD trade but lose £5,000 on another, you only pay CGT on £5,000.
CGT Exempt Amount and CFD Trading
For the 2025/26 tax year, the CGT exempt amount is £3,000. Profits within this threshold incur no tax. Above it, you pay CGT on the excess. A £5,000 profit means £2,000 becomes taxable. Loss offsetting remains valuable—it actively reduces your tax exposure across the tax year.
Costs: Spread Betting vs CFDs in the UK
Costs differ substantially between these instruments. Spread betting uses wider spreads—typically 2-3 pips wider on GBP/USD than CFD equivalents. CFDs charge commissions ranging from 0.1% to 0.5% of trade value. A £10,000 FTSE 100 trade could cost £10–£50 depending on your broker.
Overnight Financing and CFD Trading
CFDs impose overnight financing charges—typically 0.5% to 2% annually. Holding a £10,000 GBP/USD position overnight at 0.5% costs roughly £5 daily. Spread betting avoids these charges entirely, making it preferable for traders holding positions longer-term without financing costs.
Ownership and Trading Strategy: Spread Betting vs CFDs in the UK
Ownership matters for dividend eligibility. CFDs give you beneficial ownership—you receive dividends from held positions. A Royal Dutch Shell CFD entitles you to dividend payments. Spread betting involves no ownership, so dividends don't apply. However, spread betting offers broader market access and flexible conditions, making portfolio diversification simpler.
Short-Term Trading and Spread Betting
Spread betting suits short-term traders exploiting small price movements. Its range of instruments—forex, indices, commodities—and flexible conditions appeal to traders avoiding asset ownership. CFDs suit longer-term, strategic positions where ownership and dividend capture add value.
Both instruments serve different strategies. Analyse your approach, timeframe, and tax position carefully before deciding which aligns with your goals.
