Are you a crypto investor or trader in the UK? Do you know how your cryptocurrency activities are taxed? Understanding crypto tax rules is crucial to avoid penalties and ensure compliance with HMRC (Her Majesty’s Revenue and Customs) regulations. In this guide, we’ll break down the 2025 crypto tax rules in the UK in simple terms, so you can navigate your tax obligations with ease. Whether buying, selling, trading, or earning crypto, this article will help you understand what you need to do.
What is Crypto Tax in the UK?
In the UK, cryptocurrency is not considered currency but rather an asset, similar to shares. Therefore, depending on the nature of the transaction, it is subject to taxation under Capital Gains Tax (CGT) and Income Tax. HMRC has clear guidelines on how crypto is taxed, and it’s important to follow them to avoid penalties.
Capital Gains Tax (CGT) on Crypto
When you sell, trade, spend, or gift your crypto (except to your spouse or civil partner), any profit you make is subject to Capital Gains Tax. Here’s what you need to know:
- CGT Rates (as of October 30, 2024):
- 18% for basic rate taxpayers (income up to £50,270)
- 24% for higher and additional rate taxpayers (income above £50,270)
- Tax-Free Allowance:
- For the 2024-2025 tax year, you can earn up to £3,000 in capital gains tax-free. This means if your total gains from all sources (including crypto) are below this threshold, you won’t pay any CGT.
- When CGT Applies:
- Selling crypto for fiat currency (e.g., GBP).
- Trading one crypto for another.
- Using crypto to pay for goods or services.
- Gifting crypto to someone other than your spouse or civil partner.
Income Tax on Crypto
If you receive crypto as income, such as through mining, staking, airdrops, or as payment for goods and services, this is considered taxable income. Here’s how it works:
- Income Tax Rates:
- 0% on income up to £12,570 (personal allowance).
- 20% on income between £12,571 and £50,270 (basic rate).
- 40% on income between £50,271 and £125,140 (higher rate).
- 45% on income above £125,141 (additional rate).
- Personal Allowance:
- The first £12,570 of your income is tax-free, but this allowance is reduced if your income exceeds £125,140.
- Examples of Taxable Income:
- Mining rewards.
- Staking rewards.
- Airdrops.
- Receiving crypto as payment for work or services.
When Do You Need to Pay Crypto Tax?
You need to pay tax on crypto when:
- You sell crypto for fiat currency (e.g., GBP).
- You trade one crypto for another.
- You use crypto to pay for goods or services.
- You gift crypto to someone other than your spouse or civil partner.
- You receive crypto as income (e.g., mining, staking, airdrops).
However, some activities are tax-free:
- Buying crypto with fiat currency.
- Holding crypto (HODLing).
- Transferring crypto between your wallets.
- Donating crypto to charity.
- Gifting crypto to your spouse or civil partner.
How to Calculate Crypto Tax
Capital Gains Tax Calculation
To calculate your CGT, you need to determine your gain or loss for each transaction. Here’s the formula:
- Gain or Loss = Disposal Value – Acquisition Cost
- Disposal Value: The value of the crypto when you sold or disposed of it.
- Acquisition Cost: The value of the crypto when you bought it, plus any allowable costs (e.g., transaction fees).
- Allowable Costs:
- Transaction fees.
- Advertising costs for finding a buyer or seller.
- Costs of drafting contracts.
- Valuation costs for calculating gains.
- A proportion of pooled costs for the same type of crypto.
- Pooled Costs:
- If you have multiple transactions of the same crypto, HMRC uses a “pooled cost” method. All purchases are grouped into a single pool, and the average cost is used to calculate gains or losses.
- Exception: If you buy and sell the same type of crypto within 30 days, these transactions are not pooled.
Income Tax Calculation
For income from crypto (e.g., mining, staking), you simply report the value of the crypto received as income at the time you received it. This is added to your total income and taxed at your marginal tax rate.
Reporting Your Crypto Taxes
All crypto-related gains and income must be reported to HMRC through your Self-Assessment Tax Return. Here’s what you need to know:
- Tax Year:
- Runs from April 6th to April 5th of the following year.
- Deadlines:
- Paper returns: October 31st following the tax year.
- Online returns: January 31st following the tax year.
- New Reporting Requirement:
- From April 6, 2025, the SA108 form will include a specific box for cryptoassets. This means you must report all your crypto activities.
- What to Report:
- Capital gains from selling, trading, or disposing of crypto.
- Income from mining, staking, airdrops, or other sources.
- How to Report:
- Use HMRC’s Government Gateway online service for your Self Assessment Tax Return (Government Gateway).
- If you’re unsure, consider using crypto tax software like Koinly or Coinledger to help calculate and report your taxes accurately.
Penalties for Not Reporting
Failing to report your crypto taxes can lead to severe consequences:
- Penalties:
- Up to 20% of the capital gains tax is due, plus interest.
- Additional penalties up to 200% of the tax due for deliberate non-compliance.
- Possible criminal charges and jail time for tax evasion.
- HMRC’s Monitoring:
- HMRC has access to data from UK crypto exchanges through a data-sharing program.
- From 2026, new OECD CARF regulations will require exchanges to collect and report customer data, including full name, address, wallet address, and transaction details. This will make it easier for HMRC to track non-compliant taxpayers.
Keeping Records for Crypto Taxes
You must keep detailed records of all your crypto transactions. HMRC may request these records during compliance checks. Here’s what to include:
- Type of crypto.
- Date of acquisition and disposal.
- Number of units bought and sold.
- Value in GBP at the time of transaction.
- Wallet addresses.
- Bank statements showing transactions.
- Pooled costs for same-type cryptos (if applicable).
How Long to Keep Records:
- At least a year after the Self Assessment deadline (January 31st following the tax year).
Tip: While exchanges may provide transaction reports, you should keep your own records because exchanges don’t track pooled costs.
Other Taxes Related to Crypto
Inheritance Tax
- If your estate is worth more than £325,000 when you die, your crypto holdings will be included at their fair market value.
- This applies to both crypto and NFTs (non-fungible tokens).
VAT
- There is no VAT when you buy crypto with fiat currency.
- However, when you use crypto to pay for goods or services, standard VAT rates apply (currently 20%).
Business Tax
- If your crypto trading is frequent, organized, and sophisticated, it may be treated as a business. In this case, profits are subject to Income Tax (not CGT).
- Most individual traders are not considered businesses, so their profits are taxed as capital gains.
Future Changes and HMRC Monitoring
- OECD CARF Regulations (from 2026):
- Crypto exchanges must collect and report customer data, including full name, address, wallet address, and transaction details.
- Reporting starts in January 2026, with the first reports due by May 2027.
- Non-compliance can result in fines of up to £300 per user.
- HMRC’s Data-Sharing Program:
- Major exchanges like Coinbase already share data with HMRC for users with fiat inflows over £5,000.
- HMRC can also access transaction data from 2014 and KYC (Know Your Customer) information.
These measures mean HMRC is increasingly able to track and monitor crypto activities, so compliance is more important than ever.
Tips to Minimize Crypto Taxes
- Use Tax-Free Allowances:
- Take advantage of the £3,000 CGT allowance by realizing gains within this limit.
- Use the £12,570 personal allowance for income tax.
- Dispose in Low-Income Years:
- If possible, sell or dispose of crypto in years when your overall income is lower to benefit from lower tax rates.
- Donate to Charity:
- Donating crypto to charity can provide Income Tax relief. You can claim the difference between the higher and basic rate based on the fair market value of the donation.
- Claim Losses:
- If you have capital losses, you can offset them against gains. Unused losses can be carried forward indefinitely but must be registered within 4 years.
- Negligible Value Claim:
- If your crypto becomes worthless (e.g., due to lost keys), you can claim it as a disposal at £0 value. File this in the year of loss.
