The application Filing CBSO

The new Filing application for the preparation, validation and filing of annual accounts will be operational from 4 April 2022.

To access the new Filing application, we use CSAM, the government portal. The Filing application provides both the preparation of annual accounts and the filing to the Central Balance Sheet Office of files created via the application or via commercial accounting packages.
