Μake us preferred on Google Greece is officially ending the era of paper invoices. Starting February 2, 2026, businesses will be required to issue and receive invoices electronically, marking a major step in the government’s efforts to increase transparency and combat tax evasion.
The new system, overseen by the Independent Authority for Public Revenue (AADE), allows real-time cross-checking of invoices and requires businesses to use secure, approved digital platforms. For domestic transactions, electronic invoicing is mandatory, while invoicing for non-EU transactions is also compulsory. EU-bound invoices remain optional for the time being.
The February 2 rollout applies initially to large businesses with gross revenues exceeding €1 million for the 2023 fiscal year. A transitional period until March 31, 2026, will allow these companies to run existing accounting systems alongside the new electronic invoicing forms. For smaller businesses, mandatory e-invoicing begins on October 1, 2026, with a transition period extending to December 31, 2026.
Companies can issue electronic invoices through AADE-approved providers offering comprehensive e-invoicing solutions or through the government’s free “Timologio” application.
Tax incentives encourage early adoption. Businesses implementing the system at least two months before the mandatory start date can receive 100% accelerated depreciation for equipment and software purchases, as well as a 100% bonus on e-invoicing service expenses in the first year.
