From January 1, 2026, a new reporting requirement for cryptocurrencies will come into force in the EU: the so-called DAC8 Directive (“Directive on Administrative Cooperation, 8th Amendment”). This extends the EU's automatic exchange of information to crypto transactions and implements the OECD's international Crypto-Asset Reporting Framework (CARF) at EU level.
What specifically will change?
More transparency for tax authorities: From 2026, crypto-asset service providers such as 21bitcoin or wallet providers will have to collect certain data on users and report it to the respective tax authorities from 2027.
Exchange: The tax authorities will then automatically exchange this data with each other.
What data? For example, identification data (tax ID, address), transaction details (purchases/sales, transfers), and other relevant information about crypto transactions will be reported.
What is the purpose of DAC8?
The aim of the new rules is to combat tax evasion and avoidance and ensure that profits from crypto transactions are correctly recorded in tax returns. As cryptocurrencies are used across borders, DAC8 creates a uniform framework for the international exchange of information between tax authorities.
What does this mean for you as a 21bitcoin user?
You have to specify your country of tax residence and tax ID in your 21bitcoin profile.
Your crypto activities will become more visible to tax authorities via your trading platforms and wallet providers.
You are still responsible for submitting correct tax returns, even if data is transmitted automatically (except for Austrian taxpayers, for whom we take care of crypto taxes).
Good documentation of your transactions and profits/losses will therefore become even more important in order to avoid discrepancies with the tax authorities.
In a nutshell
What? EU directive on the automatic reporting of crypto data to tax authorities (DAC8 & CARF).
When? Applies from January 1, 2026, first reporting period for data from 2026, reporting by July 2027.
Important for you: More transparency – but also more responsibility when filing your tax return.
The introduction of DAC8 is a step towards greater transparency and control in the European crypto market. All service providers must implement the new regulations. For you as a 21bitcoin user, this means that your Bitcoin investment will be more regulated. But don't worry, your Bitcoin will remain your property – at 21bitcoin, we only process your data to the extent required by law.
