In a recent joint announcement [âïž], Greece’s deputy minister of National Economy & Finance, Giorgos Kotsiras, and the Governor of Greece’s tax authority, AADE, Giorgos Pitsilis, have officially postponed the start of mandatory e-invoicing for large businesses by one month in the first phase of implementation.
Although adoption is already high, with roughly 34,000 of Greeceâs 38,000 large companies having activated e-invoicing at the time of the announcement, authorities have decided to allow businesses more time to prepare for the reform:
- The obligation will now begin on March 2, 2026, instead of February 2, 2026, and will apply to large companies (annual revenue > 1 M⏠in 2023)
- A transitional period will then run for those large companies from March 2 to May 3, 2026, allowing for gradual implementation
- The second phase of the mandate starts on October 1, 2026, where e-invoicing will become mandatory for all companies, again with a transition period, this time lasting until December 31, 2026.
Companies can comply either through certified e-invoicing service providers or by using AADEâs free tools, including the Timologio application and the myDATAapp, which also support public procurement invoicing.
The authorities also outlined the penalties for non-compliance:
- For failure to issue an electronic invoice for transactions subject to VAT, a fine of 50% of the VAT that would have resulted from the unissued invoice is imposed.
- For failure to issue an electronic invoice for transactions not subject to VAT, fines are imposed per tax audit, respectively âŹ500 for entities keeping single-entry books and âŹ1,000 for entities keeping double-entry books.
