Spread Betting vs CFDs: What is the Difference?
⚡ Read this before you open your next trade
Spread betting and CFDs (Contracts for Difference) are the two main retail instruments for speculating on price movements without owning the underlying asset. They look identical on most broker platforms — same charts, same leverage, same spreads — but they are legally and fiscally very different. Spread betting is treated as gambling in the UK (tax-free); CFDs are derivatives subject to capital gains. This guide unpacks every difference that matters to retail traders.
What Spread Betting Is
Spread betting is a derivative product unique to the UK and Ireland. You "bet" a specified amount per point of movement — e.g., £5 per point on EUR/USD. If EUR/USD moves 50 points your way, you win £250. If it moves against you, you lose £250. Legally it is classified as a gambling product, which is why the UK exempts wins from capital gains tax and stamp duty.
Because it is a bet, spread betting is only offered by firms with UK gambling licenses. Leading providers are IG, City Index, Spreadex, CMC. Margin and stops work identically to CFDs; the only real difference is the tax treatment and legal wrapper. Spread bettors technically never own anything — they just bet on the price difference.
What CFDs Are
A CFD is a contract between you and the broker to exchange the price difference of an asset from when you open to when you close the position. You never own the underlying; you only settle the P&L in cash. CFDs are legal financial derivatives, available globally except the US (banned by SEC).
CFDs are flexible — you can trade forex, indices, stocks, commodities, and crypto, all from one broker. Leverage under EU/UK retail rules is 30:1 on majors, 20:1 on minors, 10:1 on gold, 5:1 on stocks, 2:1 on crypto. Costs include spreads, commissions (on stock CFDs), overnight financing (swap), and a guaranteed-stop premium if you opt for one. Unlike spread bets, CFD gains are subject to capital gains tax in most jurisdictions.
Cost Comparison
Spread betting spreads are usually 0.2–0.5 points wider than CFD spreads from the same broker — this is how spread bet providers monetize the "tax-free" benefit. On EUR/USD you might see 0.6 pip CFD vs 0.9 pip spread bet. No commission on either (forex). On stock CFDs, commission applies (0.08–0.10% per side); stock spread bets usually have no explicit commission but wider spreads.
Overnight financing is identical in percentage terms. On a £100k long position on EUR/USD, you pay the same overnight interest whether spread bet or CFD. Guaranteed stops (optional) cost a premium on both. For UK residents, the tax savings on spread bets typically dwarf the wider spread, making spread betting cheaper overall for active traders.

Tax Treatment (UK Focus)
In the UK, spread betting wins are completely tax-free — no capital gains tax, no stamp duty, no income tax. This is because HMRC classifies it as gambling. Losses are not deductible. For a high-rate UK taxpayer (45%) with £10,000 annual trading profit, this saves £4,500 vs equivalent CFD profits (subject to CGT above the £3,000 allowance).
CFDs in UK/EU are capital gains assets. UK CGT is 20% above the £3,000 allowance for higher-rate taxpayers on financial assets. In Germany, CFD gains are subject to Abgeltungsteuer (25% + solidarity). In Poland, CFDs fall under 19% tax on capital gains. Always consult a local tax advisor — some jurisdictions treat CFDs as business income, which has different implications than investment income.
Which Is Better for You?
If you are a UK resident and consistently profitable, spread betting is almost always the better choice — the tax savings easily offset slightly wider spreads. Most UK spread betters are also retail traders in high tax bands, so the benefit is magnified.
If you are outside UK/Ireland, spread betting is not an option — default to CFDs. If you are UK-based but losing money, CFDs may let you carry forward losses against future gains (check with HMRC). If you trade professionally as a sole trader or limited company, CFD profits may be classified as trading income, which is taxed differently (and losses deductible). The right answer depends on your jurisdiction, income level, and activity frequency.

Frequently Asked Questions
Is spread betting really tax-free?
Yes, in the UK and Ireland. HMRC classifies it as gambling under the Betting and Gaming Duties Act. This covers wins of any size, including professional-level income. Note: if HMRC judges that spread betting is your sole profession AND you depend on it, they may reclassify it — but in practice this almost never happens because proving dependency is hard.
Can I use spread betting outside the UK?
Most spread bet providers restrict accounts to UK and Irish residents due to FCA gambling licensing. Some jurisdictions (Germany, France) do not recognize the product legally. EU residents typically default to CFDs; Australians use CFDs or futures; Americans cannot use either CFDs or spread bets — they trade futures or spot forex under NFA.
Do spread bets and CFDs use the same platform?
Usually yes. UK brokers like IG offer both products on the same platform. The ticket interface is almost identical — on CFD you enter "lots," on spread bet you enter "pounds per point." Charts, indicators, stop-loss orders and execution are identical. The only functional difference is the P&L label and tax treatment at year-end.
Which has better spreads?
CFDs almost always have tighter spreads than spread bets at the same broker — usually 0.2–0.5 points tighter. This is the provider's way of charging for the "tax-free" benefit of spread betting. For active traders, the wider spread still comes out much cheaper than paying 20% CGT on CFD profits.
Can I hedge with spread betting?
Yes. Many UK residents hold long-term stocks in ISAs or pensions (tax-sheltered) and use spread bets for tactical hedges — e.g., shorting the FTSE 100 index during bearish signals. The hedge loss is not deductible against the underlying ISA gain, but the hedge gain is tax-free. Structurally, it allows for very tax-efficient portfolio management.
