From 1 January 2026 if you provide cryptoasset services in the UK, you’ll have new responsibilities for collecting data and reporting it to HMRC.

All UK-based ‘reporting cryptoasset service providers’ (RCASPs) will need to report to HMRC if the business either transacts cryptoassets on behalf of users or  provides a means for users to transact cryptoassets eg. exchanges, brokers, dealers. 

Return data required for individual users : * name * date of birth * home address * country of residence  * for UK residents, their National Insurance number or Unique Taxpayer Reference * for non-UK residents, their tax identification number (TIN) and the country where it was issued * If a user cannot be issued a TIN (for example, because their country does not issue TINs), then  no need to provide one.

Return data required for entity users, including companies, partnerships, trusts and charities : * legal business name * main business address for UK companies, their company registration number * for non-UK companies, their tax identification number and the country where it was issued * For some entities, you’ll also need to collect information about their controlling person.

Return data required for each transaction : * value * type of cryptoasset * type of transaction * number of units

The first report is due by 31 May 2027, giving details for 1 January 2026 to 31 December 2026. In future years, submission is by 31 May each year, giving details for the previous calendar year.

If you do not follow the rules, you may be charged a penalty of up to £300 per user.
