Cryptoasset ownership has grown in popularity from what was originally a niche technology into a major alternative investment, with a wide spectrum of investor types. According to research from the Financial Conduct Authority, around 12% of UK adults owned crypto in 2024, up from 4% in 2021.
Users of cryptoassets will need to ensure that their UK tax and reporting obligations are up-to-date.

HMRC published their Cryptoassets Manual on 30 March 2021 after several years of consultation. The manuals represent HMRC’s interpretation of current legislation and case law for internal staff use, however there is not currently any UK legislation regarding cryptoassets as it is an emerging and complex technology. Professional commentators have already challenged HMRC’s approach, so these uncertainties will inevitably lead to disputes between taxpayers and HMRC.

If you swap or sell cryptoassets as personal investments, Capital Gains Tax may be owed. Capital gains/losses would be calculated in a similar way to investing in shares.

As an emerging and complex class of assets, there is not currently any UK legislation regarding cryptoassets upon which HMRC has formed its views, and professional commentators have already challenged some elements of HMRC’s approach.
Despite this, ownership of cryptoassets is becoming more common with investing seen as completely legitimate. As testament to this, in November 2024, the Financial Conduct Authority (FCA) published a roadmap regarding the UK’s crypto regulation regime.
This rise in investment and uncertainties surrounding legislation will undoubtedly lead to disputes between taxpayers and HMRC in the future.
HMRC has many statutory information powers to request information from taxpayers and third parties such as traditional financial institutions.
In addition, HMRC has also started approaching crypto exchanges. In Autumn 2020, a popular exchange reportedly advised its users that it would be providing details to HMRC about customers who had received cash payments over £5,000 during the tax year.
In November 2023, the international Crypto-Asset Reporting Framework was agreed between almost 50 countries including the UK.
From January 2026, the Organisation for Economic Development’s (OECD) announced the Cryptoasset Reporting Framework (CARF) will be introduced, which means that cryptoasset service providers will need to send user and transactions information directly to HMRC.
All of this will give HMRC a wealth of data regarding cryptoassets, and it will only be a matter of time before they start to approach taxpayers with what they’ve found.
The UK tax system is based on taxpayers self-assessing the amount of tax owed, after which HMRC may ask questions within a strict enquiry window. It is likely that HMRC will be taking a keen interest in taxpayers who have reported cryptoasset income or gains on their returns.
Taxpayers are obliged to maintain adequate records, which HMRC may request to see in order to verify the accuracy of the return. Adequate records may include cryptoasset holdings and exchanges used, transaction ledgers, valuations, public and private keys, and bank statements showing deposits/withdrawals in traditional currency.
If a return is found to be inaccurate, HMRC can assess penalties and charge interest on any unpaid tax, which may significantly increase the overall liability for the taxpayer.
