The UK government is taking a major step in tightening cryptocurrency regulations. Starting in 2026, all crypto service providers in the UK must collect and report user data under the OECD’s Crypto-Asset Reporting Framework (CARF).
This global initiative aims to increase tax transparency and combat evasion in the cryptocurrency space. By aligning with over 40 countries, including EU member states, the UK is set to reshape how crypto platforms handle user data.
What Is CARF and Why Is the UK Adopting It?
Developed by the Organisation for Economic Co-operation and Development (OECD), the Crypto-Asset Reporting Framework (CARF) addresses tax evasion issues in the digital asset world. The UK’s decision to adopt CARF aims to:
Enhance transparency in cryptocurrency transactions
Align with global tax standards
Prevent offshore tax avoidance using digital assets
By adopting CARF, the UK is joining a growing list of nations committed to securing better reporting practices for crypto transactions.
Important Dates to Remember
2026: UK-based and foreign crypto service providers (CASPs) must begin collecting user identity and transaction data.
May 31, 2027: The first deadline for annual reporting.
Even if you are not based in the UK, any crypto service provider serving UK users must comply.
Which Users Are Affected?
The new regulations apply to all UK tax residents and users from countries that are also implementing CARF rules (expected to include over 40 jurisdictions)
CASPs will need to collect data from all users, but the reporting requirements are focused on those residing in CARF-compliant countries.
Additionally, the EU’s DAC8 regulations will complement CARF, imposing similar transparency measures on crypto firms targeting European users.
What Data Must Be Collected?
Crypto firms will be required to gather the following data for reporting user identity details and transaction data, including volumes, timestamps, and counterparties.
These requirements apply to crypto exchanges, custodial wallets and transfer service providers.
Consequences for Non-Compliance
Failure to comply with CARF rules can lead to:
Fines of up to €300 per non-compliant user
Penalties for late, inaccurate, or missing filings
CASPs are strongly encouraged to begin building the necessary reporting infrastructure well in advance to avoid costly penalties.
Challenges for Decentralized Platforms
The new CARF rules will likely pose challenges for decentralized exchanges (DEXs) and non-custodial wallets, which prioritize user privacy and flexibility. These platforms may find it difficult to align with CARF’s stringent data collection and reporting requirements.
Industry experts are eagerly awaiting further guidance from the UK government, as some firms are considering relocating due to the high cost of compliance.
Final Thoughts: A New Era for Crypto Regulations
The UK’s adoption of CARF marks a significant shift toward regulation in the crypto sector. While the intent is to boost transparency and security, there is concern within the community that it could infringe on privacy and decentralization, values highly cherished in the crypto world. As the 2026 deadline approaches, crypto businesses must decide whether to adapt, prepare, or consider relocation.
