DAC8 FAQ | DAC8 Resources

Short answers to the most common questions about DAC8, CARF, the data collected, the timeline, the risks, the alternative and Bull Bitcoin’s legal action.

What is DAC8?

DAC8 is Directive (EU) 2023/2226. It extends automatic tax-information exchange between EU Member States to crypto-assets. It requires crypto-asset service providers to collect and transmit information about their clients and their reportable transactions.

When does DAC8 apply?

Collection obligations start on 1 January 2026. The first reporting period is the 2026 calendar year. The first automatic exchange between tax authorities is scheduled for September 2027, for the data collected over 2026.

What data is reported?

DAC8 covers identification data and transactional data: identity (name, home address, date of birth), tax residence, tax identification number, transaction types, transaction values, dates and transfer information, including operations with no tax relevance.

Why does Bull Bitcoin oppose DAC8?

Bull Bitcoin does not oppose the principle of crypto taxation. The opposition concerns mass automatic collection of sensitive crypto data, which exposes millions of citizens, including their relatives, without sufficient demonstration of necessity and proportionality. Linking identity, addresses, public transaction history and values can expose holders and their families to physical risk if the data leaks or is abused.

Is DAC8 the same as CARF?

No, they are not the same. CARF is the OECD global framework for automatic crypto-asset reporting. DAC8 is the EU directive that applies a similar logic inside the European Union, with the specificities of EU law and administrative cooperation between Member States.

Why is a blockchain address sensitive?

On a public blockchain, an address can reveal a transaction history. Once it is linked to a civil identity, it can expose far more than a balance: habits, counterparties, past flows and sometimes future movements.

What alternative exists?

French law already provides for the right of communication (droit de communication): a targeted, motivated request addressed to a third party to obtain information about an identified taxpayer. It is a less intrusive route than mass automatic collection.

What does the action before the Conseil d’État seek?

The action brought by Bull Bitcoin targets the French decree transposing DAC8. It challenges in particular the over-transposition, the procedure and the disproportionate infringement of fundamental rights.
