CARF | ARKK

Does it affect me?

CARF applies to Reporting Cryptoasset Service Providers (RCASPs), including exchanges, wallet providers, brokers, and intermediaries. If your business facilitates crypto transactions or holds customer data linked to crypto activity, you are likely in scope and may also need to support reporting by other institutions.

What do I need to do?

You will need to perform due diligence on users, collect tax residency and self-certification data, identify reportable accounts, and report transaction-level data annually. This includes details on asset type, transaction value, and activity type, all submitted in a structured XML format.

What's the deadline?

Data collection begins on 1 January 2026, with the first reporting period covering the 2026 calendar year. UK firms must register with HMRC by 31 January 2027, with the first CARF report due by 31 May 2027.
