Greek tax authority AADE has postponed the mandatory B2B e‑invoicing launch to 2 March 2026, with a two‑month soft launch ending 2 May 2026 for large resident businesses. All other resident taxpayers must adopt the system from 1 October 2026, and a new penalty regime and early‑adopter incentives have been announced.
It launches on 2 March 2026, with a two‑month soft launch that ends on 2 May 2026.
Non‑compliance may result in a fine equal to 50 % of the VAT amount for VATable transactions, or a fixed €500 or €1,000 penalty for non‑VAT transactions depending on the accounting system.
All other resident taxpayers must adopt the system from 1 October 2026, with a transitional period until the end of the year.
Early adopters integrating at least two months before the deadline receive 100 % additional depreciation of technical equipment and software costs, and a 100 % increase in deductible expenses for invoice production, transmission, and archiving during the first 12 months.
