The option for customer tests for CESOP is now available.

Reporting agents and data transmitters can apply for activation via the BZSt online.portal and carry out a connection attempt to the customer test environment to test whether the technical implementation works and CESOP reports can be transmitted on a test basis.

Please note that the CESOP reports are not yet checked for technical correctness and can only be transmitted up to a size of 1 MB.

You will always receive a rejection as a validation result with the following content:

"In the current expansion stage of the CESOP test environment, validation is not yet connected - see publication on the Internet at https://www.bzst.de/DE/Unternehmen/Umsatzsteuer/CESOP/cesop_node.html"

As soon as the next expansion stage is put into operation, corresponding information will be published on the CESOP website.

Information on activation can be found in the communicaton manual and other documents.
