Greece Delays Mandatory B2B E-Invoicing for Large Businesses to March 2026 with Transition Period

• Greece postponed mandatory B2B e-invoicing for large businesses to March 2, 2026, with a transition period until May 3, 2026.
• The delay applies to companies with over €1 million in 2023 revenue, as part of the first rollout phase.
• During the transition, businesses can use existing systems or the Tax Authority’s free tools, but must declare their start date as March 2, 2026.
• Penalties for non-compliance begin May 3, 2026, and include fines of 50% of VAT or €500/€1,000 for non-VAT cases.
• The change is a short transition period, not a reform delay, to help businesses prepare.
