- Greece is rolling out two major digital tax reforms: mandatory B2B e-Invoicing and e-Transportation reporting, both linked to the myDATA platform to improve tax oversight and reduce fraud.
- B2B e-Invoicing began for large companies (turnover above EUR 1 million) on March 2, 2026, with full mandatory adoption for all companies starting October 1, 2026.
- Greece uses a clearance model for e-Invoicing, meaning invoices must be validated through myDATA before being sent to buyers.
- The e-Transportation system requires electronic transport documents before goods move, with shipment reference numbers used to track and compare transport data against invoice data.
- Phase B of e-Transportation has been delayed and extended for testing until October 11, 2026; digital logistics event reporting starts October 12, 2026, and item-level product classification becomes mandatory on January 1, 2027.
