The Greek Independent Authority for Public Revenue (AADE) is set to scrutinize the cryptocurrency activities of Greek taxpayers on various platforms, both within Greece and abroad. This initiative arises from Greece's participation in the OECD's international automatic information exchange system for digital assets. Under the new law (No. 5273/2026) that ratifies the Multilateral Competent Authority Agreement (MCAA), the AADE will gain access to transaction volumes and incomes derived from cryptocurrency activities, rendering these previously unknown data points accessible to tax administration authorities.

The implementation of this new regulatory framework means that cryptocurrency service providers will now be held to similar monitoring standards as traditional banking institutions, where investors' activities are tracked closely. This transition is crucial, as it aims to ensure transparency and compliance within the cryptocurrency market by making it more difficult for individuals to evade tax obligations through cryptocurrency transactions. Tax authorities are expected to leverage this information to enforce tax laws more effectively and to combat tax evasion related to digital currencies.

Overall, this move signals Greece's commitment to aligning its taxation policies with international standards, particularly in the evolving space of digital assets. As the cryptocurrency market grows and evolves, regulatory measures like these highlight the need for governments to adapt their practices and frameworks to ensure fair taxation and to safeguard the revenue integrity of the state, reinforcing the importance of compliance among taxpayers in the crypto economy.
