Spread betting vs. CFD trading: key differences and tax implications
Spread betting and Contracts for Difference (CFDs) allow traders to speculate on price movements in financial markets without owning the underlying asset. While they share characteristics—specifically leverage and the ability to go long or short—their legal and tax treatments differ significantly, particularly in the United Kingdom. We break down the structural differences for 2026.
Mechanics: How they work
- Spread Betting: You bet a specific amount of money (e.g., £10) per 'point' of movement in an instrument. Your profit or loss is the difference between the entry and exit price multiplied by your stake per point. It is technically classified as gambling in the UK.
- CFDs: You trade a specific number of units (e.g., 100 shares). The profit or loss is the difference between the opening and closing price of the contract, multiplied by the number of units. CFDs are classified as a financial derivative.
The Tax Advantage: Spread Betting's Edge
In the UK, the primary reason for the popularity of spread betting is its tax status.
- Capital Gains Tax (CGT): Profits from spread betting are currently exempt from CGT in the UK and Ireland. This means 100% of your gains are yours to keep. CFD profits, however, are subject to CGT (after your annual allowance is exhausted).
- Stamp Duty: Both spread betting and CFDs are exempt from UK Stamp Duty Reserve Tax (SDRT) because you never take physical ownership of the shares.
- Loss Offsetting: Because spread betting is tax-free, you cannot use losses to offset gains elsewhere. Conversely, CFD losses can be used to offset other capital gains, which may be preferable for high-net-worth individuals or those with complex tax profiles.
Cost Structure and Execution
- The Spread: In spread betting, the broker's fee is usually built entirely into the spread (the difference between the buy and sell price). CFD brokers may charge a spread OR a commission per trade, especially on equities.
- Financing Costs: Both instruments incur 'overnight holding costs' if a position is kept open past the daily market close. This is essentially interest paid on the leveraged portion of the trade.
Risk Management in 2026
Both products are leveraged, meaning you can lose more than your initial deposit unless your broker provides Negative Balance Protection (standard for retail clients under FCA/ESMA rules). In 2026, we emphasize that spread betting is often more accessible for smaller retail accounts, while CFDs are better suited for professional traders who require direct market access (DMA) and the ability to hedge existing physical portfolios.
Note: Tax laws are subject to change. Investors should consult with a qualified tax professional regarding their specific circumstances.
