Crypto derivatives trades are no longer limited to institutional investors. They’ve become an increasingly popular strategy for UK crypto traders looking to hedge risk or boost profits. But with greater opportunities also come greater tax complexities.
Unlike regular crypto buying and selling, derivative contracts involve speculation without directly owning the underlying asset. That difference changes how HMRC treats them for tax purposes. Depending on your activity, you could be subject to Capital Gains Tax, Income Tax, or even be classed as a trader under HMRC’s guidelines. Knowing the right classification is key to reporting correctly and avoiding penalties.
In this guide, we break down how HMRC taxes crypto derivatives and leverage in the UK, what records you need to keep, and how to stay compliant.

What Are Crypto Derivatives?
Crypto derivatives are financial contracts that derive their value from the price of an underlying cryptocurrency like Bitcoin or Ethereum. Instead of directly buying or selling crypto, you enter into a contract that lets you speculate on price movements.
These tools often come with leverage, allowing you to trade with more capital than you own. For example, with 10x leverage, a £1,000 position gives you market exposure worth £10,000.
While this can lead to larger profits, it also increases the risk of significant losses. Because you don’t own the underlying asset, HMRC applies different tax rules to these transactions compared to regular crypto trading.
Types of Crypto Derivatives and How They Work
Crypto derivatives offer different ways to trade price movements without directly buying or selling crypto assets. Understanding how each type works can help you assess both the risks and tax responsibilities involved. Here are the most common types explained simply:
Contracts for Difference (CFDs)
CFDs allow traders to speculate on the rising or falling prices of cryptocurrencies without actually owning the underlying asset. Instead, you enter into a contract with a broker to exchange the difference in a crypto’s value between the time you open and close a position.
These are especially popular for short-term trades and often involve leverage, which can magnify gains or losses. Since the crypto asset is never physically held, these are treated differently from spot trades in the eyes of HMRC.
Example:
You open a CFD on Ethereum at £1,600 and close it at £1,800. You don’t own ETH at any point, but you still earn £200 from the price change. If ETH had dropped instead, you’d have made a loss.
Futures Contracts
A futures contract is an agreement to buy or sell a specific amount of crypto at a set price on a future date. These are often used for hedging or speculative purposes, allowing traders to lock in prices or bet on future market direction.
Profits or losses are realised at settlement when the contract is closed, and they can be either in the form of crypto delivery or a cash adjustment based on the price movement.
Example:
You agree to buy Bitcoin at £22,000 in two months. When the contract expires, Bitcoin is trading at £25,000. You earn a £3,000 profit because you locked in a lower buy price.
Options Trading
Options trading gives you the right, but not the obligation, to buy (call option) or sell (put option) a crypto asset at a fixed price within a set period. This flexibility makes options popular in volatile markets, where prices move quickly.
Traders use options to limit potential losses while still participating in upside potential. However, the upfront premium paid for the option may become a loss if not exercised.
Example:
You buy a call option to purchase Bitcoin at £20,000 within 30 days. If Bitcoin rises to £24,000, you can buy it at the agreed £20,000 and either keep it or sell it for a £4,000 gain.
Margin Trading
Margin trading involves borrowing funds from a crypto exchange to increase your position size. It allows you to control larger trades with a smaller initial investment, but also exposes you to bigger losses if the market moves against you.
Most platforms require a minimum deposit (called margin), and if the value of your position drops too far, you may be forced to close the trade or add more funds.
Example:
You deposit £1,000 and trade with 5x leverage, giving you £5,000 worth of buying power. If the asset increases by 10%, you make a £500 profit. But if it drops by 20%, your full £1,000 deposit could be wiped out.

How HMRC Views Crypto Derivatives?
HMRC treats crypto derivatives, such as CFDs, futures, options, and margin trades, differently from regular crypto trading. Since derivatives do not involve holding the underlying crypto asset, HMRC considers them financial contracts that give rise to contractual rights and obligations.
As a result, they are not covered under the standard cryptoasset manual but instead fall under broader tax principles found in the corporate finance manual.
In most cases, profits or losses from crypto derivatives are subject to Capital Gains Tax (CGT) or Income Tax, depending on how HMRC interprets the nature of your activity. The next section explains this situation in detail.
When Do You Pay Tax on Crypto Derivatives?
Understanding when your crypto derivatives activity becomes taxable is key to staying compliant with HMRC. Unlike standard crypto trades, derivatives create unique tax scenarios based on how and when you enter and exit positions. The tax treatment depends on the structure of the transaction and whether HMRC views your activity as casual investing or a trade.
Capital Gains Tax for Most Investors
In most cases, profits from crypto derivatives such as CFDs, futures, and options are taxed under Capital Gains Tax (CGT). You trigger a CGT event when you close a position, and the profit or loss is based on the difference between your entry and exit values.
If you realise gains on multiple trades during the tax year that exceed the annual CGT allowance (£3,000 for 2024–25), you must report and pay CGT on the excess amount.
HMRC requires detailed records for each trade, including:
- The date you opened and closed the position
- Contract values
- Profit or loss realised
- Any trading fees and interest paid
These records will help you calculate your capital gain or loss for each transaction and complete your Self-Assessment tax return accurately.

Income Tax If Treated as a Trade
In rare cases, HMRC may consider your crypto derivative activity to be a trade. This typically applies if you are trading frequently, at high volume, and to generate income. If your activity meets the ‘badges of trade’ criteria, your profits will be taxed as trading income under Income Tax rules.
This means:
- Your derivative profits are added to your total taxable income
- You may need to pay National Insurance contributions
- You can deduct allowable trading expenses, such as platform fees and software costs
However, most individual investors do not meet the criteria for a trading classification, and their derivative profits fall under CGT instead.
Miscellaneous Income in Some Situations
If HMRC cannot classify your crypto derivative gains under CGT or trading income, they may treat them as miscellaneous income.
This can happen if the derivative contract doesn’t qualify as a capital asset but still results in an economic benefit. In this case, the income is taxed at your regular Income Tax rate, and allowable expenses can be deducted.
Always maintain accurate records, as HMRC will assess the nature of your transactions to determine the right tax treatment. When in doubt, consult a tax professional or use HMRC-compliant software to ensure proper categorisation.
Can You Offset Losses from Derivatives?
If you’ve made a loss while trading crypto derivatives, you might be able to use those losses to reduce your overall tax bill. However, how these losses are treated depends on whether your derivative trading falls under capital gains, income, or miscellaneous income.
Capital Losses Offset Capital Gains
Most crypto derivative trading activities are treated under Capital Gains Tax. If this applies to you, then any losses you make can be offset against your capital gains from other crypto disposals or investments. For example, if you made a £4,000 gain from selling Bitcoin and a £2,000 loss from a failed CFD trade, you can offset the loss and only pay tax on the £2,000 net gain.
You must report the loss in your Self Assessment return for it to be counted. If you do not have any gains in the current tax year, you can carry forward the loss to offset future capital gains, as long as you report the loss within four years of the end of the tax year in which it occurred.
Losses from Trading Income or Miscellaneous Income
If HMRC treats your derivative activity as a trade, and your losses are considered trading losses, you may be able to offset these against other income sources, such as employment income, rental income, or even gains from other trading activity. However, this is only possible if you meet HMRC’s conditions for being classified as a trader.
In cases where derivative profits or losses are treated as miscellaneous income, the losses typically cannot be offset against other income. Instead, they may only reduce the same type of miscellaneous income. This area can be complex and is best discussed with a tax advisor to understand your eligibility.

Keeping Records for HMRC Compliance
Accurate and complete record-keeping is essential for UK crypto investors, especially when trading complex instruments like derivatives. HMRC requires that you maintain records of all transactions to correctly calculate your tax liabilities and provide proof if requested.
What Do You Need To Record?
For each crypto derivative trade, you should record the following details:
- The date you opened and closed each position
- The type of derivative used (e.g., CFD, futures)
- The name of the underlying crypto asset
- The contract value at entry and exit
- The profit or loss on each trade
- Any fees, charges, or interest related to the trade
These records help calculate capital gains or income and support your tax return if HMRC requires clarification. Missing or incomplete records can result in incorrect tax filings or penalties.
How Long to Keep Records?
HMRC recommends keeping all crypto and financial records for at least five years after the 31 January filing deadline of the relevant tax year.
This means if you filed your 2024–25 tax return by 31 January 2026, you should retain your records until at least 31 January 2031.

Frequently Asked Questions
Is Day Trading Crypto Derivatives Treated Differently by HMRC?
HMRC generally treats the frequent trading of crypto derivatives as speculative activity. However, if your activity resembles a business or meets the badges of trade, HMRC may consider it a trade, making your profits subject to Income Tax instead of Capital Gains Tax. This is assessed case by case.
Are Leveraged Losses on Margin Trading Tax-Deductible?
Losses from margin trading may be deductible if your trades fall under the Capital Gains Tax rules. However, losses exceeding your gains cannot reduce other taxable income unless your activity qualifies as a trade. Always maintain clear records of your leveraged positions, interest paid, and resulting gains or losses.
Do I Pay Tax If I Close a Derivative Position Without Profit?
If no profit or loss is realised when closing a position, there is generally no tax due. However, fees or costs related to entering and exiting the position may still impact your tax calculations. Accurate reporting ensures your return reflects the correct gain, loss, or break-even result.
What Happens If My Derivative Contract Is Liquidated?
If your position is forcibly closed due to liquidation, it is treated as a disposal. HMRC will require you to calculate any gain or loss at the point of liquidation based on the remaining value. This event is taxable under Capital Gains Tax unless trading income rules apply.
Can I Reinvest Derivative Gains to Defer Tax?
Reinvesting profits from crypto derivatives does not defer your tax liability in the UK. HMRC requires you to report and pay tax on gains in the tax year they are realised, regardless of reinvestment. You must include these gains in your Self-Assessment tax return accordingly.
