Greece is set to roll out a new generation of digital tools in 2026 to crack down on tax evasion and uncover hidden income, according to the country’s draft budgetary plan submitted to the European Commission.

At the heart of the new measures are the taxation of cryptocurrencies, the universal adoption of electronic invoicing, and the creation of the Property Ownership and Management Register (MIDA). Together, these initiatives form part of the Independent Authority for Public Revenue’s (AADE) expanded digital arsenal.

Starting Feb. 2, 2026, businesses will be required to issue and receive e-invoices, except in specific public contract cases. The integration with AADE’s information systems aims to minimize errors, reduce delays, and prevent irregularities. The move also includes the introduction of a Digital Dispatch Note for all sectors, digitizing the entire goods movement and delivery process.

A digital customer registry—already mandatory for automotive-related businesses such as repair shops, car washes, and rental companies—will be expanded to other sectors, including event services.

The upcoming MIDA platform will connect data from the Land Registry, AADE records, and the power distribution operator (DEDDIE) to improve the accuracy of property declarations and expose undeclared assets, square meters, and rental income.

AADE also plans to deploy artificial intelligence through a Business Intelligence and Data Analytics system to detect tax evasion patterns. Complementary systems for Compliance Risk Management (CRM) and Enterprise Risk Management (ERM) will help monitor and analyze corporate tax compliance.

By 2026, a comprehensive tax framework for cryptocurrencies will close a long-standing gap in the Income Tax Code. Greece will also implement EU rules on the minimum taxation of multinationals to ensure fair competition.

Finally, businesses will gain the option of advance tax rulings—allowing them to know in advance how specific transactions will be taxed—bolstering predictability and investor confidence in Greece’s business landscape.
