Global Crypto Reporting Tightens as CARF Rollout Nears in 2026

- CARF starts on Jan. 1, 2026, launching coordinated global crypto tax reporting rules.
- Exchanges must collect tax residency data and report user balances and transactions.
- Retail users face higher audit risk as cross-border crypto data sharing expands globally.
Global crypto regulation is entering a decisive phase as governments prepare to activate a unified reporting regime. The Organization for Economic Co-operation and Development has finalized the Crypto-Asset Reporting Framework, known as CARF. The framework would take effect on Jan. 1, 2026, setting a clear start date for coordinated international crypto reporting.
CARF would be applicable in some 48 jurisdictions including the UK and EU. Early-adopting jurisdictions would start gathering harmonised data from crypto exchanges and digital asset entities.
CARF Expands Data Collection and Cross-Border Tax Transparency
The protocol also sets up a uniform system for tracking cryptos behavior. Relevant service providers need to gather further customer details. This should generally involve checks of tax residency and accurate identity verification. Exchanges also need to monitor user balances and transaction details throughout the reporting year.
Once collected, the data would not remain confined to national systems. Tax authorities would exchange the information across borders. Existing international data-sharing agreements would support this process. The structure mirrors reporting regimes already applied to traditional financial accounts.
Lucy Frew, partner and head of the global Regulatory & Risk Advisory Group at Walkers, described CARF as a fundamental regulatory shift. She said it could reshape compliance expectations for crypto businesses and their customers. According to Frew, the framework introduces a level of transparency not previously seen in the digital asset sector.
Frew said the impact would be visible at the onboarding stage. Platforms require more detailed tax-related information from users. Account reviews are also expected to increase. Reporting obligations would extend well beyond domestic markets.
She warned that firms delaying preparation could face regulatory and reputational consequences. Early preparation allows companies to manage compliance risk more effectively. It also helps maintain customer trust as reporting standards tighten.
In the case of exchanges, CARF is a structural rather than an updating change. Platforms will be required to plug the framework into currently running Know Your Customer and Anti-Money Laundering systems. Onboards processes would have to be reengineered to effectively capture the tax self certification and residency details.
Reporting infrastructure would also require upgrades. Platforms must produce standardized, machine-readable reports. Governance frameworks may need revision to ensure oversight and data accuracy. Staff training would be required across compliance, engineering, and support teams.
Global Platforms Face Compliance Pressure as CARF Tightens Oversight
The challenge is greater for global platforms. Firms operating in CARF and non-CARF regions must manage overlapping regulatory regimes. Internal coordination becomes critical. Engineering, compliance, and customer service teams must work closely to avoid reporting gaps.

UK-licensed exchanges are among the first affected. CoinJar operates within the UK regulatory perimeter. CEO and co-founder Asher Tan said users would be asked to provide additional tax residency information as CARF rules are phased in.
Tan said execution is the central challenge. Platforms must meet regulatory expectations without disrupting user experience. Clear communication and simple processes remain essential.
Tan also highlighted a strategic dimension. Platforms that adapt effectively may gain credibility. As crypto activity moves closer to the mainstream financial system, compliance is becoming a competitive factor. Users may increasingly prefer regulated platforms.
For retail users, CARF does not introduce new taxes. Instead, it strengthens enforcement of existing obligations. A UK-based practitioner known as The Bitcoin & Crypto Accountant emphasized this point. He said the framework improves visibility rather than changing tax law.
From 2026 onward, His Majesty’s Revenue and Customs would receive standardized data directly from exchanges. This includes information from overseas platforms.
The practitioner said most compliance issues stem from omissions. Offshore exchange activity is often unreported. Frequent small disposals are assumed to be immaterial. Some users also misreport decentralized finance or non-fungible token transactions.
He warned that reported data may be used to review earlier tax filings. Historic mismatches could trigger follow-up inquiries. Users with unresolved issues were urged to act early. Voluntary disclosure options remain available before full CARF reporting begins.
