Taxpayers can download the public key of the new certificate even before its replacement on March 15, 2023, through the FINA certificate search engine (http://rdc.fina.hr/certificate-search/) or on the website of the Tax Administration.
The Tax Administration recommended to taxpayers to contact the manufacturer/maintainer of the software solution for fiscalization they use and/or their IT support for help in downloading and storing the public key of the server certificate, because otherwise, after replacing the certificate on the Central Server of the Tax Administration, the fiscalization of their receipts will be questionable.
Before the server certificate of the production system expires, the server certificate of the fiscalization test system cistest.apis-it.hr will be renewed on March 27, 2023, at around 4:30 p.m., where the upcoming change will be able to be tested.
