New Version of e-Invoice Validator Released by Croatian Tax Authority

The Croatian Tax Administration has released an updated e-Invoice validator with technical fixes and enhancements to improve accuracy, stability, and validation of structured invoice data. The authority confirmed that the Core Usage Specification remains unchanged, as the updates affect only validator logic and technical processing, not business rules.

The Croatian Tax Administration has released a new version of the e-Invoice validator, introducing a series of technical improvements and bug fixes. The update aims to enhance the system's accuracy and stability, particularly in processing and validating structured invoice data submitted through the national e-Invoicing framework.

The updated validator includes the following changes:

• HR-BR-43 – Corrected use of the ContractDocumentReference element instead of OrderReference.
• HR-BR-32 – Fixed issues related to the processing of decimal values and rounding.
• HR-BR-45 – Improved handling of multiple previous invoice references.
• HR-BR-28 & HR-BR-30 – Implementation of validation rules to ensure data compliance.
• HR-BR-36 – Correction of rule control logic.
• HR-BR-16 – Adjusted context for the cac: Item element.

The Tax Authority emphasized that the Core Usage Specification of the e-Invoice with extensions has not been modified, as these updates strictly pertain to the technical functioning of the validator and not the business rules themselves.
