Croatia E-Invoicing Solution for Fiscalization 2.0 Compliance
Starting January 1, 2026, all businesses in Croatia must switch to e-invoicing for B2B, B2C, and B2G transactions. Paper invoices will no longer be valid.
Invoices must follow a structured format, be delivered via the Peppol network, and require real time reporting to the Croatian Tax Administration (Porezna uprava)
With experience across 30 countries and strong SAP Add On know how, Melasoft ensures your transition to e-invoicing is fast and reliable.
What Is Fiscalization 2.0?
Croatia is launching Fiscalization 2.0, a national reform that will:
- Make e-Invoicing mandatory for all B2B, B2G, and B2C transactions
- Require real-time reporting of invoices to the Tax Administration
- Use the Peppol network for secure, standardized document exchange
From 2026, paper invoices will be a thing of the past. Businesses must transition to a fully digital invoicing workflow, or risk non-complianceOpen Melasoft Portal
Legal Framework at a Glance
The Croatian Ministry of Finance introduced a new Fiscalization Act to enforce structured, real-time e-invoicing:
- Adopted in 2025, entering into force on September 1, 2025
- Based on EU Directive 2014/55/EU and aligned with EN 16931 standards
- Allows mandatory B2B e-invoicing following Croatia’s EU VAT Directive derogation request (Art. 218 & 232)
- Enforces digital signature, structured formats, and electronic archiving
This Act combines e-invoicing and tax control into a unified legal obligation.

How Croatia Plans to Implement Peppol and Reporting
As of today, Croatia has not officially confirmed whether it will use the 4-Corner or 5-Corner model. However:
Melasoft continuously monitors regulatory updates. We’ll align your systems with the final published specifications whether it’s 4-Corner, 5-Corner, or a hybrid approach
Open Melasoft Portal
Until further technical specifications are published, businesses should prepare for:
Peppol-based invoice delivery
(4-Corner)
Real-time reporting obligations to the Tax Administration may mirror some 5-Corner behavior, but are expected to be handled via parallel APIs or via the Access Points
Current technical plans suggest a Peppol 4-Corner model for invoice exchange
