The Croatian Tax Administration has released updated versions of the e-Invoice validators and technical schemas used within the Fiscalization 2.0 system, following a regular review of system performance and validation controls.
The update introduces refinements to validation rules and extensions to certain technical fields in the eFiskalizacija and eReporting schemas, aiming to improve data consistency and interoperability between system participants. The changes are technical in nature and do not alter the business content of the e-Invoice, but ensure more consistent validation across the fiscalization ecosystem.
The new versions will enter production on March 15, 2026, at 08:00, during the scheduled system maintenance window to minimize disruption for users.
The Tax Administration has invited access points participating in the e-Invoice exchange network, ERP providers, accounting software developers, and other authorized entities transmitting fiscal messages to download the updated documentation and adjust their systems accordingly.
The updated specifications are available in the revised “Specification of Basic e-Invoice Usage with Extensions”, published on the Tax Administration’s website.
The authority also confirmed that it will continue monitoring the operation of Fiscalization 2.0 and improving the system based on feedback from taxpayers, accounting professionals, software vendors, and system access points.
For technical implementation support, software providers and access points may contact APIS IT d.o.o. via the dedicated support email: fiskalizacija.help@apis-it.hr.
Additional documentation and guidance are available in the Fiscalization section of the Croatian Tax Administration website.
