Quick answer
CFD trading vs spread betting differs primarily on tax in the UK: spread betting profits are exempt from Capital Gains Tax for UK residents, while CFD profits are taxed at standard CGT rates after the £3,000 annual allowance. Mechanics are nearly identical. Spread betting suits UK retail traders; CFDs suit non-UK residents and traders who want to offset losses against other capital gains.
Spread betting and CFD trading are economically near-identical. Both are leveraged derivatives that track an underlying without you owning it. Both let you go long or short, both are margined, both are over-the-counter contracts with a broker. The difference is jurisdictional and tax-driven: spread betting is a UK and Ireland product taxed as gambling (i.e. not taxed for the punter), while CFDs are global products taxed under capital gains or similar regimes. If you are a UK or Irish resident, the choice is about tax efficiency. Everywhere else, the choice does not exist; CFDs are the product.
The mechanical comparison
| Feature | CFD | Spread bet |
|---|---|---|
| Position sizing | Contract size (e.g. lots, units) | Stake per point (e.g. GBP 1 per pip) |
| P&L unit | Currency of the underlying | Pounds per point movement |
| Capital gains tax (UK) | Yes, subject to CGT | No (treated as wagering) |
| Stamp duty (UK) | None | None |
| Loss offset (UK) | Can offset against capital gains | Cannot offset |
| Available outside UK/IE | Yes, globally | UK and Ireland only |
| Underlying assets | FX, indices, equities, commodities, crypto | Same range |
| Leverage caps | ESMA / FCA same caps | FCA same caps |
| Negative balance protection | Yes for retail | Yes for retail |
Position sizing: the practical day-one difference
On a CFD ticket, you select contract size. One lot of EUR/USD is 100,000 units. A mini lot is 10,000. A 20-pip move on one mini lot is USD 20.
On a spread bet ticket, you select stake per point. GBP 1 per pip on EUR/USD means a 20-pip move is GBP 20. The mental model is simpler: P&L is points multiplied by stake.
Most retail spread bettors find the per-point framing easier; CFDs reward traders who already think in notional and margin.
The tax case for spread betting (UK and Ireland)
HMRC treats spread betting as wagering. Profits are not subject to capital gains tax. Losses cannot be offset against other gains. For a profitable trader in the UK, this is a meaningful structural advantage. For a trader who expects to be net-flat or losing, the loss-offset advantage of CFDs may be more useful.
Note: this treatment depends on spread betting not being your primary trade or business. HMRC has historically applied gambling treatment to retail spread betting; the position for full-time traders is more nuanced. Tax positions vary; consult a local advisor.
The tax case for CFDs
CFD profits in most jurisdictions fall under capital gains or similar regimes. The advantages: losses can be offset against other gains, and CFD trading is recognised as a financial activity rather than gambling. Outside the UK and Ireland, this is not a choice; CFDs are the product on offer.
Which one to use
| Your situation | Better tool |
|---|---|
| UK resident, profitable trader | Spread bet (tax efficiency) |
| UK resident, learning | Either; spread bet has simpler sizing |
| UK resident, want to offset losses against gains | CFD |
| EEA resident | CFD (spread betting unavailable) |
| Outside UK/IE | CFD |
| Active hedger of a real portfolio | CFD |
Common mistakes
- Treating spread betting as risk-free because it is tax-free. The leverage is identical, the volatility is identical, the risk of ruin is identical.
- Choosing the product before the strategy. The product is a wrapper; the strategy is what pays. Decide what you are trading first.
- Ignoring overnight financing. Both products charge financing on overnight positions. The fact that spread betting is tax-free does not exempt it from financing costs.
