The CESOP XSD version is modified
The European Commission has prepared an updated version of the CESOP XSD user guide, version 5.00. The XSDs included in the document package have also been modified, with the new XSD version number being 4.03. The XSDs are now available at https://openkkk.nav.gov.hu/, in the "CESOP specification" subfolder of the "Specifications" folder.
Consequently, in addition to the currently used "XSD User Guide and XSD package v4.80/v4.02," versions "XSD User Guide and XSD package v5.00/v4.03" have also been published so that taxpayers can begin technical preparations for the changeover. The European Commission is expected to prepare the central CESOP system for use with the new 4.03 XSD version in the first quarter of 2025.
In Hungary, the planned date for the live transition to version 4.03 XSD is 25 March 2025. This means that for the first quarter of 2025, data must already be supplied using the new XSD version, and data supplied using the old XSD version will be rejected by the NTCA.
After 25 March 2025, previous data submissions can also be modified using the new XSD version via the EBT system.
Testing can be performed in the test environment from 12 February 2025.
