Points of Focus

• DAC8 broadens the EU’s tax transparency framework by bringing crypto assets into automatic information exchange systems.
• The directive closely mirrors the OECD’s Crypto-Asset Reporting Framework, positioning the EU within a coordinated international push.
• Its scope extends beyond EU-based platforms, effectively requiring non-EU service providers serving European residents to comply.

The European Union has formally begun implementing a comprehensive tax transparency regime for crypto assets with the activation of the eighth amendment to the Directive on Administrative Cooperation, known as DAC8, effective January 1, 2026. 

THE EU HAS OFFICIALLY ENDED CRYPTO PRIVACY WITH DAC8

As of January 1, 2026, the DAC8 law is live across the European Union. This marks the definitive end of anonymous crypto holdings for every resident in the member states.

Automatic Reporting: Every…

The new rules require detailed reporting on cryptocurrency transactions by regulated service providers and will significantly increase the visibility of digital asset activity for national tax authorities across the bloc.

What DAC8 requires and how it works

DAC8 expands the EU’s tax information exchange framework to include crypto-asset transactions that were previously outside the scope of automatic reporting systems. 

Under the directive, Reporting Crypto-Asset Service Providers (RCASPs),  including centralized exchanges, brokers, wallet providers, and other intermediaries, must collect customer data and report it to their national tax authority. This information is then automatically exchanged with the tax authorities of member states where the customer is a tax resident.

The reported data must include personal details such as names, addresses, and tax identification numbers, as well as transaction records covering crypto-to-fiat trades, crypto-to-crypto exchanges, and transfers initiated through these platforms. 

DAC8’s definitions draw from the OECD’s Crypto-Asset Reporting Framework (CARF) and standards such as the Common Reporting Standard, aligning crypto reporting with frameworks already applied to traditional financial accounts.

Under CARF, participating countries, over 50 including the UK, and eventually others such as the US will require service providers to collect and share user transaction data with their domestic tax authorities, which then share it internationally beginning in 2027. 

The DAC8 directive was adopted by the EU Council in October 2023 and must be transposed into national law by the end of 2025, with reporting obligations taking effect from the 2026 tax year.

Digital euro and regulatory convergence

The DAC8 rollout occurs against the backdrop of the digital euro initiative, an ongoing project by the European Central Bank to explore a central bank digital currency (CBDC) for retail and wholesale use across the euro area. 

In December 2025, the European Central Bank said it had wrapped up its initial preparatory work, moving the project into a new phase focused on technical implementation, industry coordination and readiness ahead of any formal approval by EU lawmakers.

While the digital euro is not yet live, its development illustrates the EU’s broader strategy to modernize digital finance infrastructure with both regulatory oversight and official digital payment innovations.

Implications for crypto users and service providers

For users, DAC8 diminishes the anonymity historically associated with crypto transactions conducted through regulated entities. While non-custodial wallets themselves are not direct reporting entities, transactions linked back to RCASPs will be visible to tax authorities under automatic exchange.

For service providers, compliance will require significant investment in data collection, verification and reporting systems, and may involve penalties established by member states for non-compliance. Regulators and industry participants are closely watching implementation progress toward the first reporting cycle, which begins after the 2026 calendar year.

DAC8 represents a significant step in the international harmonization of crypto tax reporting and reflects policymakers’ intent to bring crypto assets into the structured transparency frameworks long applied to traditional financial instruments.
