From January 2026, individuals who own cryptocurrency, such as Bitcoin, Ethereum, or Dogecoin, will be required to provide their details to service providers to ensure they are paying the correct tax.
UK crypto holders must provide personal details to crypto service providers from January 2026 or face penalties of up to £300.
What information must crypto providers collect?
Service providers will begin collecting data on users’ activities from January 2026. The new rules mean, crypto service providers must collect and report
- your name, address, and date of birth
- your tax residence
- your National Insurance number or tax reference
- a summary of your crypto transactions
Any crypto service provider that fails to report this information or submits inaccurate or incomplete reports could also be charged a penalty of up to £300 per user by HM Revenue & Customs (HMRC).

Declaring tax on crypto profits
Crypto users should already include any crypto gains or income in their Self Assessment tax returns. HMRC has introduced new dedicated sections to the capital gain pages to be completed from the 2024 to 2025 tax year.
Capital Gains Tax may be due when selling or exchanging crypto, while Income Tax and National Insurance could apply to crypto received from employment, mining, staking, or lending activities.
Anyone unsure about their tax obligations can check if they need to pay tax when they receive or sell crypto. You can also tell HMRC about unpaid tax on crypto using the cryptoasset disclosure service.
