Croatia Expands E-Invoicing to B2B Transactions, Mandate Effective January 2026 for VAT Entities

Croatia is expanding electronic invoicing from the public sector to the broader business community.
Since July 1, 2019, suppliers to public authorities must use the national e-invoicing platform.
The platform is managed by FINA and integrated with the Peppol network for secure transactions.
The government plans to extend e-invoicing to B2B transactions starting with a testing phase on September 1, 2025.
The full mandate for B2B e-invoicing begins on January 1, 2026, for VAT-registered companies established in Croatia.
From January 1, 2027, the requirement will include non-VAT registered businesses.
The Directorate-General for Tax Administration oversees the initiative with a centralised e-invoicing system.
The system will validate invoices in real time and integrate with the Fiscalization 2.0 programme.
The initiative aims to reduce VAT fraud and streamline administrative processes.
Businesses need to invest in compliant systems to meet new requirements.
Croatia’s approach aligns with similar initiatives in other EU countries.
