The Tax Administration in Croatia announces support for the TLS v1.3 encryption protocol for fiscalization services 

The Tax Administration has announced that it will introduce support for the TLS v1.3 encryption protocol on the Central Information System (CIS) side in the test environment of the fiscalization service on September 1, 2023. The fiscalization service is a system that enables electronic communication between taxpayers and the Tax Administration regarding the issuance of invoices and receipts. More on the TLS v1.3 encryption protocol as follows.

The TLS v1.3 encryption protocol is a standard that provides a higher level of information security during data exchange over the internet. The Tax Administration will support TLS v1.1, v1.2, and v1.3 encryption protocols in the test environment of the fiscalization service starting in September.

The Tax Administration has invited producers and maintainers of software solutions for fiscalization to check the compatibility of their solutions with the CIS of the Tax Administration via TLS v1.1, v1.2, and v1.3 protocols in September and, if necessary, make the required adjustments in their solutions.
