- Entrepreneurs can now apply for certificates needed to use the National e-Invoice System (KSeF); the Ministry of Finance launched the Certificate and Authorization Module on November 1.
- Certificates and authorizations issued via this module will be legally valid and usable for KSeF 2.0 only from February 2026, when KSeF becomes mandatory for the first group of taxpayers.
- The Ministry of Finance warns to treat certificates and login data with the same care as online banking credentials; certificates issued to individuals must not be shared.
- For companies, certificates are linked to the entity, not individuals, and the company is responsible for managing and tracking their use.
- The MCU functionalities (applying for, downloading, and managing certificates and authorizations) are available only via a web browser, not through API.
