Making money from crypto in the UK is taxable under HMRC cryptocurrency tax rules. “His Majesty’s Revenue & Customs” – HMRC generally treats crypto assets as taxable when you realize gains from them. How your crypto income is taxed depends on the type of crypto activity you do.
It is highly essential for UK residents to be aware of future potential changes in reporting transparency. This article analyses the changes in HMRC tax rules and the implementation of the global Crypto-asset Reporting Framework (CARF). Also, learn about UK tax on CFD trading here.
What are the new HMRC crypto tax rules for 2026?
The new data-collection requirements are part of the Organization for Economic Development (OECD) and Crypto-asset Reporting Framework (CARF), which intend to improve compliance with existing tax rules.
The following are the new HMRC crypto tax rules UK residents and CASPs must adhere to for 2026: Crypto asset service providers in the UK should collect the information about:
- All individual users
- All entity users
- Crypto asset transactions for users in the UK and other CARF countries. Such transactions include:
Value
Type of crypto asset
Type of transaction
Number of units
Reporting by individuals
UK residents will need to provide certain identifying details to any service provider you are using to buy, sell, transfer, or exchange crypto assets. The information you provide links your crypto asset activity to your tax record. This makes it easier for the UK tax department to find out what relevant tax you need to pay.
Here is the information individual users must provide:
- Full name, date of birth, address.
- Tax identification number, which is the National Insurance Number or Unique Taxpayer Reference (UTR) in the UK.
Reporting by entities
You can be an entity user who owns a company, partnership, trust, or charity. Here is the information the entity users must provide:
- Legal business name
- Main business address
- Company registration number, if owning UK-based companies
- Tax identification number, for non-UK companies
Reporting by crypto asset service providers
The crypto asset service providers in the UK will have new responsibilities for collecting data and reporting it to HMRC. However, they will only need to report on users who are tax residents in the UK or another country that is signed up to the CARF rules.
When you use a UK crypto asset service provider, but you do not live in the UK, if the country you live in follows the same rules, HMRC will share your information with your country’s tax authority.
When you use a non-UK crypto asset service provider, but you live in the UK, if the country of your crypto asset service provider follows the same rules, the country’s tax authority will share your information with HMRC.
How HMRC tracks crypto in the UK (2026 update)
HMRC can track crypto as it has:
- A data-sharing program with UK exchanges via direct data feeds powered by the CARF system.
- Cross-matching crypto exchanges reports against self-assessment tax returns using the “Connect” system – a powerful AI platform, a digital watchdog.
- HMRC also works with blockchain analytics firms to track the movement on public ledgers, where it can potentially map out your entire history of that wallet, including DeFi activity.
- UK banks have been flagging transfers to and from known crypto exchanges, and this reporting is going to be more integrated in 2026. Large and frequent crypto transfers in your account will be flagged as “unexplained wealth” if they don’t align with your reported income.
Do you pay tax on crypto in the UK? (Explained simply)
Yes, since HMRC considers crypto as a capital asset, you have a taxable event at the time of disposing of it. Such activities include the following:
- Selling crypto for cash or fiat (GBP, USD)
- Exchanging crypto for another one (e.g. BTC for ETH)
- Using crypto to buy goods or services
- Gifting crypto to persons other than your spouse or civil partner
- DeFi transactions that include trading LP tokens
You must report and pay Capital Gains Tax (CGT) when your total gains exceed the annual tax-free limit. On the other hand, income tax may apply if you receive crypto assets as:
- Payment for your employment
- Rewards from mining, staking, or airdrops.

2025 vs 2026 UK crypto tax rules
Here is a comparison of the previous HMRC crypto tax framework and the changes taking effect from January 2026.
| HMRC crypto tax – old version (2025) | HMRC crypto tax – New version (effective 2026) |
|---|---|
| HMRC primarily relied on request-based formal information to obtain data on specific users. | The UK has adopted the OECD’s CARF for automatic reporting. |
| Exchanges collected data manually, only when legally compelled. | CASPs must now automatically report transaction data of UK residents to HMRC. |
| Enforcement focused primarily on high-volume and suspicious accounts. | Reporting applies to all relevant transactions for all UK customers, though no profit is made. |
| Penalties varied depending on the nature of the error. | There will be a penalty of £300 per user for non-compliance. £300 per user penalty applies to CASPs as well if they fail to report accurate information. |
Crypto asset service providers in the UK need to verify that the collected information is accurate by carrying out due diligence; failing of so will attract penalties of up to £300.
