Spread betting is tax free in the UK for most retail traders: profits carry no Capital Gains Tax and no Stamp Duty, and you do not report them to HMRC. Two conditions attach. HMRC can tax you where the betting is part of a trade you already carry on, and spread betting losses cannot be set against Capital Gains Tax on anything else.
These are the 2026/27 rules, checked on 26 August 2026.
Updated on 5 Sep 2026: the tax tool gains a second read-out, the Capital Gains Tax a spread bettor saves against the same position taken as a CFD, at the profit, band and allowance you set, with the 2026/27 rate, the £3,000 annual exempt amount and the loss-relief condition stated in the same line. The first read-out no longer repeats the difference, and the tool’s note on loss relief now points to the page’s second condition rather than restating it. No rate or allowance changed.
Updated on 3 Sep 2026: the page moved onto the site’s guide layout, with a diagram of the one question HMRC asks beside the answer and a second diagram under the loss-relief condition showing the same £5,000 loss as a spread bet and as a CFD. No figure changed.
Updated on 2 Sep 2026. The FAQ entry asking which countries spread betting is tax-free in was removed, together with its entry in the page’s FAQ schema. This page states UK law, and the question invites a list of other jurisdictions we have not sourced. No figure changed. Reviewed on 2 Sept 2026. The tool now sits directly under the answer rather than two thirds of the way down the page, so the calculation is the first thing here that does anything. Three Capital Gains Tax rates were corrected: a claim about savings on trading costs, a row in the spread betting versus share trading table, and the closing comparison all still carried the bands that applied before April 2024, on a page whose own worked comparison has published the current ones since 26 Aug. The figures themselves are not repeated here, because a wrong rate quoted in a correction note is still a wrong rate on the page. Every percentage this page states is now registered with its source and re-checked on every build. Later the same day: an attributed quotation from a named analyst was removed. He did not review this page and the attribution was wrong, and the two sentences it carried said nothing the paragraph above them had not already said. Condition 2 said this treatment is UK and Republic of Ireland law; it now says UK law, which is what the sources on this page establish.
Reviewed on 26 Aug 2026 against the primary sources. Every gov.uk citation on this page was re-fetched and checked for what it actually says, and one was wrong: BIM22017 was cited for the trading exception, when what it holds is close to the opposite: that having a system, or earning a living from betting, does not make it a trade. The exception is BIM22019, and the body and the FAQ now cite it. A sentence characterising how often HMRC pursues retail bettors was removed as an unsourced judgement, and the summary condition was corrected from "if spread betting is your livelihood" to the test the manual actually applies. Capital Gains Tax rates, the annual exempt amount and every row of the worked comparison were recomputed against gov.uk's published 2026/27 figures.

One question decides it: is the bet part of a trade you already carry on? For most retail traders it is not, and the profit is betting winnings (HMRC BIM22015, BIM22019).
Enter your stake per point, the opening and closing levels and your income-tax band. The tool shows the same trade’s outcome as a spread bet, with no Capital Gains Tax, and as a CFD, with Capital Gains Tax at 18% or 24% above the £3,000 allowance. It needs no sign-up.
Spread bet or CFD: what you keep after tax
Capital Gains Tax on the same profit, 2026/27 rates
On a £5,000 winning trade, a spread bettor keeps £5,000. A basic-rate CFD trader with the £3,000 exemption unused pays £360 CGT and keeps £4,640.
A spread bet saves £360 in tax on this trade: the Capital Gains Tax the same position pays as a CFD at the basic rate, with the 2026/27 £3,000 annual exempt amount unused. The saving runs one way, because a CFD loss is an allowable loss and a spread bet loss is not (the second condition).

Tax treatment depends on your circumstances and can change. This applies the published 2026/27 figures and is not advice.
The £3,000 annual exempt amount is a whole-year allowance, not a per-trade one. The comparison assumes the whole gain falls inside the chosen band, and it ignores the spread and overnight funding, which both products charge and neither is taxed on. Rates and allowance: HMRC, 2026/27. Spread betting profits are free of Capital Gains Tax and stamp duty for most UK residents; see the tax treatment of spread bets.
Spread betting is taxed in the UK as betting, not investing, for most retail traders. HMRC treats the profits as betting winnings (BIM22015), so no tax is due on them.
No Capital Gains Tax. You do not pay Capital Gains Tax on a spread betting profit.
No Stamp Duty. No Stamp Duty is charged on a spread bet, because you never own the asset.
No Self Assessment reporting. You do not report spread betting profits on a Self Assessment return.
No loss relief. Losses cannot be set against other capital gains.
One exception applies. Profits that form part of a trade you already carry on are taxed as trading income (BIM22019).
The Two Conditions On Tax-Free Status
The exemption is the rule, not a loophole, but it is conditional in two ways that matter before you rely on it.
1. It must not be your trade
HMRC's position is set out in its Business Income Manual. BIM22015 states the general rule that the profits of betting and gambling are not the profits of a trade, resting on Graham v Green (1925), in which a man who made his living backing horses was found not to be trading. BIM22017 adds that having a system for placing bets, or being successful enough to live on it, does not make the activity a trade either. BIM22019 is where the exception lives: betting that is an element of a trade you already carry on.
Being full-time, systematic or profitable does not by itself make spread betting a trade. Graham v Green is authority for exactly the opposite. The line BIM22019 draws is that the winnings must arise out of carrying on the trade rather than out of an opportunity the trade presents. The test is HMRC's to apply rather than yours, and it turns on your whole circumstances.
2. Losses carry no relief
The exemption runs both ways. Because a spread bet is not a chargeable asset, a losing spread bet produces no allowable loss: it cannot be set against Capital Gains Tax on shares, property or anything else, and it cannot be carried forward. A CFD trader who loses can offset; a spread bettor who loses cannot. That is the cost of the exemption, and it is the reason the choice between the two products is not automatic.
The same £5,000 loss, two products. On the spread bet it is not an allowable loss, so it cannot reduce Capital Gains Tax on anything else and cannot be carried forward. On the CFD it can be set against other chargeable gains. The exemption runs both ways.
Residency matters too: this treatment is UK law. It does not travel with you.
Is Spread Betting Tax-Free?
Yes, for most UK individuals spread betting is tax-free, unless your spread betting is deemed to be trading rather than casual investing or speculation.
The UK’s tax, payments and customs authority, the HMRC, defines spread betting as speculative gambling, rather than as a taxable investment, exempting it from Capital Gains Tax (CGT). UK financial regulator, the Financial Conduct Authority (FCA), is responsible for regulating and enforcing this tax ruling to spread betting brokers.
Stamp duty also doesn’t apply to spread betting as you’re trading on a derivative so you never actually take ownership of the underlying asset. This makes spread betting’s tax implications different to other types of trading, like share trading.
HMRC’s guidance (BIM22015/BIM22017) and the long-standing Graham v Green case confirm that gambling profits are generally not taxable.
Capital Gains Tax: Spread Betting vs Shares
One of the biggest advantages of spread betting in the UK is its tax treatment. While profits from spread betting are generally free from CGT and stamp duty, the same investment made by purchasing shares directly may attract both taxes.
Tax treatment depends on your individual circumstances and can change, so you should seek professional tax advice if you’re unsure.
Worked Example: Spread Betting vs Buying Shares
Suppose you believe a UK-listed company’s share price will rise from £10.00 to £12.00.
Buying shares
If you buy 1,000 shares at £10.00, that is a £10,000 investment. Selling at £12.00 gives you £12,000, earning you a gross profit of £2,000.
You would also pay 0.5% Stamp Duty Reserve Tax (SDRT) when purchasing UK-listed shares, adding £50 to your costs.
If your total gains exceed your annual CGT allowance, some or all of the £2,000 profit may also be subject to CGT, depending on your tax bracket. For example, if you’re a higher or additional rate taxpayer, you’ll pay 24% on your gains. This would eat a further £480 into your profit.
Spread betting
Now let’s say you open an equivalent spread bet on the same price movement and the market rises by the same amount, you generate an equivalent £2,000 profit.
Assuming you are an individual trader, no CGT is generally payable on spread betting profits (depending on your circumstances). Also, because you never take ownership of the underlying shares, you don’t have to pay stamp duty.
For many UK traders, avoiding both stamp duty and CGT is one of the key reasons to consider spread betting. However, these tax benefits should never be the sole reason for trading, as spread betting is a leveraged product and losses can exceed your initial stake.
The Same Trade, Taxed Two Ways (2026/27)
The difference is easiest to see on a single position held as a spread bet and as a CFD. Both open long on the UK 100 at 10,850 and close at 11,050, a 200-point move: £25 per point as a spread bet and 25 contracts as a CFD, producing the same £5,000 gross profit either way.

The £3,000 annual exempt amount is the 2026/27 figure and it is a whole-year allowance, not a per-trade one: if other gains have already used it, the CFD column's taxable gain is the full £5,000 and the tax is £900 or £1,200 rather than £360 or £480. The comparison also ignores the spread and any overnight funding, which both products charge and neither is taxed on.
Overnight funding is a daily charge or credit applied to a spread bet held past the broker’s cut-off, set as a rate above or below an interest-rate benchmark (City Index publishes SONIA plus 3% on long positions, SONIA minus 3% on short positions). Work out the cost for your own position with the overnight funding calculator.
Reverse the trade and the ranking reverses with it. A £5,000 loss costs a spread bettor the full £5,000, while a CFD trader can set the loss against other chargeable gains. Size a position with our spread betting calculator before deciding which side of that trade-off you want to be on.
When Spread Betting Could Be Taxable
While spread betting profits are generally free from CGT and stamp duty in the UK, there are situations where your profits could become taxable.
The main exception is if HMRC considers your spread betting activity to be a trade rather than casual investing or speculation. This is uncommon, but it may be relevant if spread betting is your primary source of income and you operate in a highly organised, business-like manner. HMRC looks at the overall facts of each case rather than applying a single rule.
If you trade frequently, rely on spread betting to earn a living, or carry out your activities as a professional business, it’s worth seeking advice from a qualified tax adviser. They can assess whether your circumstances could fall outside the usual tax treatment and explain your reporting obligations.
For most retail traders, spread betting profits remain tax-free. However, if your trading activity changes significantly (E.g.you leave full-time employment to trade exclusively) it is sensible to review your tax position.
As tax rules can change and everyone’s circumstances are different, you should not assume that spread betting profits will always remain exempt. If you’re an active or professional trader, checking your status with a tax professional can help ensure you remain compliant with HMRC requirements while understanding any potential tax liabilities before they arise.
What Are The Spread Betting Tax Benefits?
The HMRC has made three key rulings that impact you as a spread bettor:
1. No Capital Gains Tax
Your profits are exempt from capital gains tax, which can make it easier for you to manage the cost of your strategy.
2. No Stamp Duty
Spread betting is a derivative product. As you never take ownership of the asset, you won’t need to register any ownership document, which means no stamp duty.
At current rates, we’ve found this should reduce your costs by 0.5% per trade.
3. Commission-Free Trading
We’ve already covered the tax implications, but there are other costs to consider too. You won’t pay any commission when you open a spread bet, so this is one less fee to worry about.
Instead, the cost of the trade is factored into the spread, or the difference between the buy and sell price of the instrument. So if the buy price of EUR/USD is 1.0604 and the sell price is 1.0605, the spread will be one pip.
Exceptions to the No-Tax Rule
The UK does tax spread betting in some instances, and there are some exceptions to the no-tax rule. We advise you to keep these in mind.
HMRC does not normally tax spread betting profits, even if it is your main or full-time income. Tax would only arise in rare cases where the activity is shown to be run as a business rather than gambling.
If you’re trading through your limited company, you’ll need to pay corporation tax. The HMRC will consider this speculative bet to be a trading activity of your company.
Pro and Cons Table For Spread Betting Taxes
We have found a number of different spread betting advantages, such as leverage trading, a wide variety of markets to bet on, and low trading fees. One of the main benefits, we feel, is the exemption of capital gains tax and stamp duty.
However, there are a few cons to consider too.
Pros
Cons
No capital gains tax
Cannot offset your losses against your tax
No stamp duty tax
In very rare cases, HMRC may tax spread betting if the activity is proven to be a business operation, but being a full-time bettor alone does not make profits taxable.
No dividend dividend tax
It’s important that we stress these benefits are only for retail account holders. The situation is different if you are a professional spread bettor or if spread betting is your sole income.
What Is Spread Betting?
Spread betting is a method of trading the markets. You are able to speculate on the price movement of a specific financial market, without actually owning the underlying asset.
You may decide to go long (or buy), and potentially profit from a rising market. Alternatively, you can go short (sell) and potentially profit from a falling market.
The opportunity to profit in both rising and falling markets makes this an attractive method for day traders.
Spread betting and CFDs are very similar. But the main point of difference is how they are taxed. Trading
CFDs are classed as a form of investment, because there is an exchange of contracts.
Spread betting, on the other hand, is classed as a form of gambling by the HMRC, and is tax exempt as a result, at least for most retail traders.

Why Isn’t Spread Betting Taxed in the UK?
The UK is one of the only countries worldwide not to tax financial spread betting. This is due to the product’s positioning and classification by the HMRC, which regulates spread betting taxes, and taxes from other sources.
1. The HRMC Considers It Gambling
According to HMRC tax law, spread betting is a form of gambling. The HMRC’s definition also states that “no assets [are] acquired or disposed of”. You are not buying or selling any asset, and are essentially gambling on the future direction of the price.
2. The HRMC Considers It A Derivative
Spread bets are derivatives. They are linked to an instrument, but they do not involve the actual purchase or sale of that instrument.
Whenever you register an asset in your name in the UK, you’ll need to pay stamp duty tax on the registration document. As there’s no transfer of assets, there’s no document, so you don’t pay the 0.5% stamp duty tax that you would with traditional share trading.
Spread Bet Tax-Free Example: Stocks
Below, I’ll quickly outline a spread betting example which highlights the tax benefits of spread betting, compared to other traditional market speculations.
Example of Spread Betting Stocks (Tax-Free):
You decide to open a spread bet on Vodafone (VOD) shares, and go long at the buy price of 82p per share. You stake £10 per point.
So for every 1p VOD rises above 82p, you’ll profit £10.
You aren’t actually buying the shares themselves, so you don’t need to pay any stamp duty on this position. There’s no contract or registration document involved.
There’s also no commission to pay, as the position is a spread bet.
Let’s say the prediction you made turns out to be accurate. VOD rises to 92p per share. The 10 point gain makes you £100 profit, according to the formula: “price movement in points x per-point bet size”.
While you have made a profit here, HMRC does not class this profit as taxable. You won’t need to pay capital gains tax or income tax on this, as long as you’re not a professional trader, or betting on spreads as your main source of income.
Now, let’s see how much you would have had to pay if you’d traded the shares in the traditional way.
Fees on purchasing shares:
Stamp duty tax (0.5% of the asset value)
Broker’s commission (typically 1.5% of the total trade size)
Fees on closing the shares in a profit:
Broker’s commission (typically 1.5% of the total trade size)
Profits liable to capital gains tax (up to 24% of the profits)
As you can see, you’ll be able to keep more of your spread betting profits than you would with traditional share purchasing.
This does depend on the individual broker’s fees, however. So we strongly recommend checking which is the best spread betting platform UK for your trading before you choose a broker.
FAQ
Is spread betting taxable at HMRC?
No. HMRC does not tax spread betting profits for most UK individuals, and BIM22015 is the reason: it treats a bet as “merely an irrational agreement that one person should pay another person on the happening of an event”, so the winnings are neither chargeable to Capital Gains Tax nor income. BIM22017 goes further and says that having a system for placing bets, or being successful enough to earn a living from them, does not make the activity a trade. The exception sits in BIM22019. To be taxable, betting wins must come from the carrying on of a trade rather than from an opportunity presented by one. Tax treatment depends on your individual circumstances and can change, so you should seek professional tax advice if you are unsure.
Is spread betting always tax-free?
No. The exemption is the general rule and it carries two limits. BIM22019 sets the first. Betting wins are taxable where they arise from a trade you already carry on, so the same profits can be treated differently depending on what else you do for a living. The second limit runs the other way and costs you rather than HMRC. A spread bet is not a chargeable asset, so a loss on one is not an allowable loss, and it can neither reduce Capital Gains Tax on other gains nor be carried forward. Tax treatment depends on your individual circumstances and can change, so you should seek professional tax advice if you are unsure.
Do I have to declare spread betting winnings to HMRC?
No. Spread betting profits are not chargeable to Capital Gains Tax and are not income, so there is no box for them on a Self Assessment return and nothing to declare. The only reason to raise it with HMRC is if you believe your spread betting forms part of a trade you carry on, which is the exception described above.
Is spread betting classed as gambling?
For tax, yes: BIM22015 treats it as betting, which is exactly why the profits are not taxed. For regulation, no: it is a financial product sold by firms authorised and supervised by the Financial Conduct Authority, not by the Gambling Commission. The two answers are consistent, and we set the distinction out on our is spread betting gambling page.
Can HMRC tax me as a professional?
It is possible, though the test is not how much you trade. Graham v Green establishes that even a full-time, systematic bettor is not thereby trading, and BIM22017 says the same of having a system or earning a living at it. HMRC would need to show the betting arose out of a trade you were already carrying on, under BIM22019. If your circumstances are unusual, take advice rather than assuming either answer.
Can I offset spread betting losses?
No. A spread bet is not a chargeable asset, so a loss on one is not an allowable loss: it cannot reduce Capital Gains Tax on other gains and it cannot be carried forward. This is the trade-off for the exemption, and it is the main tax argument for using a CFD instead.
Are taxes the same for share trading and spread betting?
No. Buying shares outright can attract both Stamp Duty on the purchase and Capital Gains Tax on the profit, because you take ownership. Spread betting shares attracts neither, because the bet is a derivative and no ownership changes hands.
