GermanyWorldUnderstanding DAC8 Directive on crypto
DAC8 (Directive on Administrative Cooperation 8th iteration) is an EU directive that extends automatic exchange of tax information to cryptocurrency transactions. Since 1 January 2026, crypto service providers operating in the EU are required to report user transaction data — including names, addresses, tax IDs, and transaction values — to the national tax authority where they are registered. This data is then automatically shared with the tax authority of the user's country of residence. DAC8 covers exchange tokens, utility tokens, stablecoins, and e-money tokens — and aligns closely with the OECD's CARF framework.

What this means for your crypto activity
Automatic exchange reporting
EU-based exchanges are now required to report your crypto transaction data directly to your national tax authority.
Harder to under-report
Under-reporting crypto gains is significantly more difficult now that tax authorities receive direct data feeds.
Data reported
Data reported includes total proceeds, acquisition costs, and transfer values for each account.
Non-EU exchange obligations
Non-EU exchanges serving EU residents may also have reporting obligations under DAC8.
Prior-year accuracy
The reporting requirement increases the importance of accurate self-reporting in prior years.

Seeing it in action
Example scenario
Anna, a German resident, uses a French crypto exchange. The French exchange is now required to report Anna's annual transaction data to the French tax authority (as the exchange's home state), which automatically shares it with the German Finanzamt. Even if Anna does not file a tax return, the German tax authority receives data about her crypto activity and can cross-reference it against her filings.
How this works across jurisdictions
- Germany
DAC8 adopted October 2023; reporting obligations begin 1 January 2026; German Finanzamt receives crypto transaction data from EU exchanges via automatic cross-border exchange.
- World
EU-wide: DAC8 applies to all EU-registered CASPs; data automatically exchanged between all 27 EU member state tax authorities.
