Starting December 1, 2025, all businesses in Greece are required to accept payments through the IRIS system, the country’s new platform for real-time transactions between businesses and private customers.
The Independent Authority for Public Revenue (AADE) has finalized the regulatory framework linking businesses’ point-of-sale (POS) systems to tax authorities, while technical specifications have been updated to incorporate instant payment capabilities.
Transaction Limits
Daily transaction limits currently stand at €500 for payments between individuals or to businesses, with a maximum of €1,000 per day. These limits are set to increase in January 2026, allowing up to €1,000 per day and €5,000 per month for private individuals, as part of the system’s gradual expansion.
Fines for Non-Compliance
Businesses that fail to integrate with IRIS or connect their POS and cash systems to AADE risk significant fines. Penalties vary based on the business type and location. Initial enforcement includes a transitional period, with recommendations provided, especially in cases of technical issues.
Fines range from €10,000 for businesses with simple accounting records to €20,000 for those with double-entry bookkeeping. Smaller businesses in villages or non-tourist islands benefit from a 50% reduction in penalties. POS providers may face fines from €100,000 to €300,000, and outdated devices can cost €500 each.
Background
The enforcement date was postponed from October 31 to December 1, 2025, to allow businesses time to adapt and ensure smooth implementation. The measure is part of a broader tax reform titled “Taxation Reform for the Demographic issue and the Middle Class – Support Measures for Society and the Economy,” currently under discussion in the Greek Parliament.
