UK CARF: HMRC removes two dates from crypto reporting timetable

HMRC corrects its online service timetable

The United Kingdom’s tax authority, HM Revenue & Customs, updated its Cryptoasset Reporting Framework, or CARF, guidance on November 2, 2026. The guide was first published on May 14, 2025. The change does not eliminate the reporting framework. It corrects two operational dates linked to the online service that providers will eventually use to submit information.

HMRC removed January 1, 2027 as the start date for submitting reports, explaining that the service will not be available by then. It also removed the January 31, 2027 registration deadline because that deadline does not apply in the first reporting year. The current text simply says that the registration service is not live yet and that the page will be updated when it is. It would therefore be inaccurate to announce a new launch date that HMRC has not published.

Covered providers remain defined by their activities

The framework applies to cryptoasset service providers considered based in the United Kingdom. HMRC says a business falls into this category when it transacts in cryptoassets on behalf of users or provides a means for users to conduct such transactions. The examples include exchanges, brokers, and dealers. Status therefore depends on the service provided and the relevant nexus criteria, not merely on the commercial label selected by a business.

To fall under CARF, a cryptoasset must be a digital representation of value that uses a cryptographically secured distributed ledger, or similar technology, to validate and secure transactions. It must also be used for payment or investment. Central bank digital currencies and certain specified electronic money products are instead reportable under the Common Reporting Standard when they meet the relevant definitions. This distinction prevents every digital asset from being placed automatically in the same regime.

Data collection and territorial nexus still apply

An organization may be considered UK-based if it is tax resident, incorporated, managed, or has a regular place of business or branch there. For an activity spanning several CARF countries, HMRC describes a hierarchy that places tax residence first. A company that is tax resident in France but incorporated in the United Kingdom therefore reports in France; when two countries sit at the same level of the hierarchy, it may choose between them.

Covered providers must continue collecting information about their users and transactions. Depending on the data gathered, they may need to submit a report to HMRC, tell users that their details will be reported, and register with the service once it opens. Penalties may apply for non-compliance. The November 2 update therefore changes the displayed technical timetable, but it is neither an abandonment of CARF nor a general suspension of preparation duties.
