DAC8

DAC8 is the eighth amendment to the European Directive on Administrative Cooperation (DAC) in the field of taxation. Its main objective is to increase tax transparency and combat tax evasion in the crypto-asset environment. The directive introduces a new obligation for crypto-asset service providers (such as exchanges, trading platforms, or wallet operators) to collect and subsequently report information about their users and their transactions. This data will then be automatically exchanged among the tax authorities of the EU member states.

‍

The reporting obligation covers a wide range of transactions, including exchanges of crypto-assets for fiat currencies (e.g., euros, dollars), exchanges between different crypto-assets, and transfers of crypto-assets. The reported information will include the user's identification details (name, address, tax identification number) and aggregate data on their transactions for the given calendar year. All member states, including the Czech Republic, must implement the directive into their national legislation by the end of 2025, with the first reporting obligation for service providers applying to the year 2026.
