E-Invoicing in Croatia: Everything You Need to Know

Mandatory E-Invoicing from 2026:
Starting 1 January 2026, Croatia requires VAT-registered businesses to issue and report e-invoices for B2B and B2G transactions, with non-VAT entities following from January 2027.
Real-Time Reporting and Compliance:
Businesses must transmit invoice data in real time to the Tax Authority under Croatia’s new Continuous Transaction Controls (CTC) model, enhancing VAT compliance, invoice tracking, and fraud prevention.
National Platform and Tools:
Croatia’s decentralized e-invoicing model supports Peppol and FiskApplication, with optional use of certified providers. A free invoicing tool, MIKROeRAČUN, will support small non-VAT businesses with e-invoice creation and storage.
E-Reporting and Invoice Details:
Both issuers and recipients must report invoice data, including payment status, bank details, and product codes. Recipients must report rejected invoices, while issuers must declare failed or non-electronic invoice submissions.
