Is spread betting tax free?
Under HMRC rules, not only is spread betting tax free on your winnings, you aren't normally treated as carrying on a trade. Spread betting lets you bet on whether a financial price will rise or fall without buying the asset itself. You don't pay Capital Gains Tax on profits, and you can't claim tax relief on losses.
They aren't taxable on the profits, and no relief is received for their losses. The bookmaker arranging the spread bet is taxable.
Is spread betting tax free in the UK for everyone?
HMRC's basic view is that betting and gambling aren't trading, so almost all private individuals pay no tax. HMRC says this plainly in its tax rules for spread betting: 'They aren't taxable on the profits, and no relief is received for their losses.' No court in the UK has ever found that a regular punter was carrying on a business.
The one main exception is the bookmaker who takes the other side of your account. Operating an organised activity for profits from people who gamble is treated as trading, which means the bookmaker is taxed.
Tax applies to your own wins only when they arise directly from an existing trade. The contract terms and economic substance of what you do are checked by HMRC. Companies placing financial spread bets are also subject to separate tax rules.

Spread bet losses and tax relief
You can't claim any deduction for money lost through a spread bet against your wages, any business profits or investment gains. Is spread betting tax free UK wide? On your winnings, yes, though any losses stay entirely your own cost.
The tax you normally pay on selling an investment for more than it cost is called Capital Gains Tax. That system doesn't cover spread bets, so HMRC ignores your winning and losing bets on the tax return you file.

Spread betting and CFD tax rules compared, plus deposit risks
With a contract for differences, known as a CFD, you agree with a broker to exchange an asset's price change. If the price rises, a long position pays you; if it falls, a short position does. Our spread betting vs CFDs page compares how both accounts work.
The treatment of CFD trading in the UK is different from spread bets: HMRC applies Capital Gains Tax rules unless your profits are trading income. Closing a CFD includes every credit and debit in your gain or loss calculation, including commission and interest or dividend adjustments.
| Rule or feature | Spread betting | Retail CFD |
|---|---|---|
| HMRC classification | Betting and gambling, not normally a trade | Financial future under capital gains rules |
| Tax on profits | Not taxable for most individuals | Taxed under Capital Gains Tax unless trading income |
| Tax relief on losses | No relief for losses | Allowable loss calculated when closed out |
| Items in tax calculation | None for a normal punter | Price change, commission and interest or dividend adjustments |
| Stamp Duty Reserve Tax on shares | Not payable as you don't buy the shares | Not payable as you don't buy the shares |
Being tax free doesn't lower the financial risk you carry. The derivatives broker you use holds authorisation under the Financial Services and Markets Act 2000, and market risks stay the same. According to HMRC's CFD guidance, the deposit commonly equals 20% of the asset value, or ranges from 5% to 35%. You may need to increase that deposit when the asset price changes, or lose the money you've put down.

Is spread betting classed as gambling, or as regulated trading?
For tax purposes, HMRC places what spread betting is within its betting and gambling rules rather than treating it as a trade. New kinds of games of chance have appeared over time, but HMRC still applies the same basic principle: the bet isn't a business for whoever places it.
In practice, regulated spread betting companies take your financial spread bets rather than a high street bookmaker. The brokers we cover include ActivTrades, Capital.com, CMC Markets, FxPro, IG, Pepperstone, Spreadex and Vantage, all offering spread betting accounts alongside CFDs. Spread betting isn't offered by eToro, Plus500, Trading 212 or XTB, though each of them does offer CFDs.

Common questions answered
Are my UK betting winnings subject to tax?
No, HMRC places betting and gambling outside trading income for a regular punter. A bet, say the courts, is an agreement to pay someone if an event occurs, so the tax burden sits with the bookmaker alone.
Is it against UK law to spread bet?
No, spread betting on financial markets is legal in the UK through brokers holding authorisation under the Financial Services and Markets Act 2000. First, try a forex demo account, or read our guide on forex trading legality in the UK.
Is trading CFDs tax free in the UK?
No, HMRC applies the Capital Gains Tax regime to retail CFDs unless it counts your profits as trading income. You still pay no Stamp Duty Reserve Tax on share CFDs, as no actual shares are bought.
Do forex spread bets avoid tax in the UK?
Yes, HMRC uses the same betting rules for a spread bet based on a currency pair, share price or index. How currency CFDs differ is covered in our forex trading tax in the UK page, which also explains whether trading is tax free.
