- Greece is moving into the final prep stage for mandatory electronic invoicing.
- From October 1, 2026, businesses not in the first phase must use e-invoicing for applicable B2B transactions; firms over €1 million revenue were already included from March 2, 2026.
- Businesses must choose a certified provider or the Tax Authority’s free apps and file the required declaration naming their invoicing method.
- Invoices will be sent automatically to myDATA and receive a MARK; a transition period runs from October 1 to December 31, 2026 before e-invoicing becomes exclusive for covered transactions.
- A separate digital goods-movement requirement starts October 12, 2026, aimed at real-time reporting and stronger anti-evasion controls.
