The reporting era
A new era of international cryptoasset reporting is beginning.
CARF is an OECD-based reporting framework for in-scope cryptoasset service providers. Understanding it is about preparation and accurate records — not about assuming anyone automatically owes more tax.

Sequence
How the UK timings fit together.
From 1 January 2026
UK due diligence and collection obligations begin for in-scope reporting cryptoasset service providers (RCASPs).
During 2026
Users of UK cryptoasset service providers may be asked for identity and tax-residence information — for example name, date of birth, address and a tax identification number such as a National Insurance number or UTR.
1 January – 31 May 2027
First UK provider reports are made to HMRC, covering calendar year 2026.
Session topic under review
Certain crypto lending and liquidity arrangements have been discussed in the context of a 'no gain, no loss' treatment from 6 April 2027. We will only publish session detail on this after checking primary sources.
What it is not
Reporting is scoped, not total.
Information requirements apply to providers that are in scope, for the information they are required to collect. It is not the case that every wallet or every record is visible to anyone.
