Do the Contribution Account Codes have to be sent in every month?

Yes. In the same way as the normal paper-based procedure. However, if no TC2 is sent in for two months, this can cause the withdrawal of the authorisation code for the System.

Can different Contribution Account Codes be sent in separately?

Yes, for all the CAC's that are affiliated and have workers. One or more affiliation documents can be sent in at the same time. Companies can also be grouped according to their type of agreement, critical date or any other useful criterion.
