Greece E-Invoicing: Key Updates and Compliance Roadmap

The Greek government is pushing ahead with a nationwide shift toward Greece e-invoicing, aligning with broader EU digital tax initiatives. Businesses operating in Greece—whether domestic or cross-border—must prepare for upcoming mandates that will impact how they issue, receive, and report invoices.

Several bodies are responsible for shaping and enforcing Greece e-invoicing requirements:

• Ministry of Finance – Policy and legislative framework.
• Independent Authority for Public Revenue (IAPR) – Implementation and tax compliance oversight.
• Ministry of Digital Governance – Digital infrastructure and interoperability standards.

• All public authorities only accept structured e-invoices (compliant with EN 16931 and transmitted via Peppol) for public procurement contracts.
• The mandate is phased-in: it began for major contracting authorities and central government bodies in late 2023 and early 2024, with the final phase—covering all remaining public expenses (typically those above €2,500)—becoming mandatory as of September 1, 2025.

• February 2, 2026: Large companies (revenue above €1M in 2023) must start issuing e-invoices. A short transition phase will run until March 2026.
• October 1, 2026: All remaining businesses must comply, with transition until December 2026.
• Scope: Domestic sales and services, as well as cross-border transactions with non-EU companies, all under the Greece e-invoicing framework.

• Currently, no e-invoicing mandate is planned.

• Invoice format: Greece has adopted peppol BIS Billing 3.0, aligned with EU standards.
• Reporting: All invoices (B2B and B2C) must be reported in real-time through the myDATA platform, which is a critical part of the Greece e-invoicing ecosystem.
• Data covered: Sales invoices, purchase invoices, accounting records, and retail fiscal data.

Failure to comply can lead to serious consequences:

• 10% of net value per missing/late invoice.
• Capped at €250 per day and €100,000 per year.
• Repeat offenses can double or quadruple penalties, up to €100,000/year.

• No financial fines, but invoices may be rejected or payments delayed, impacting cash flow.

• Assess readiness: Large companies should already be testing Greece e-invoicing workflows ahead of February 2026.
• Upgrade systems: Ensure ERP/accounting software can generate Peppol BIS Billing 3.0 invoices.
• Integrate with myDATA: Establish real-time reporting connections for all sales and purchase records.
• Monitor compliance deadlines: SMEs must be ready by October 2026.
