- Greece postponed the start of mandatory e-invoicing for the second group of businesses to November 2, 2026 (from October 1, 2026).
- The second implementation period covers remaining businesses, including those with declared gross revenue up to €1 million based on the 2023 income tax return.
- A gradual transition period runs from November 2, 2026 through January 31, 2027, during which businesses may still use existing invoicing/transmission methods alongside the new e-invoicing channels.
- From February 1, 2027, affected invoices and their data must be issued/transmitted exclusively through an approved e-invoicing provider or the Tax Authority’s timologio and myDATAapp tools.
- The mandate applies to covered domestic B2B transactions, certain transactions with non-EU businesses, and relevant B2G transactions.
