December 1st will mark IRIS payments’ inclusion to compulsory methods in transactions

As stated by the AADE in a relevant announcement following the new decisions of its administrator Giorgos Pitsilis, the regulatory framework for the interconnection of businesses with the Tax Authority and the integration of instant payments at points of sale is being completed. The central principle of the new system is: “Payment collection (card, IRIS) – Mandatory issuance of a receipt from the cash system”, with the aim of full digital control of transactions and the fight against tax evasion.

With decisions A.1147/2025 and A.1160/2025, the interconnection protocols of the previous regulations (A.1098/2022 and A.1155/2023) are amended and the method of integrating Instant Payments into cash systems is determined.

Businesses will be able to accept direct payments via:

• POS terminals,
• Electronic Data Issue Provider Services (EDPS).
• Compliance deadlines

Relevant technology and payment companies must adapt to the new framework by the end of November 2025:

Payment Service Providers (Acquirers & NSPs):

Until 28/11/2025 to submit an updated Declaration of Conformity.

Financial Information and ERP companies (import, manufacturing, marketing, technical support):

Until 28/11/2025 to submit an updated Declaration of Conformity.
