The transmission from eBilanz-Online to the fiscal authority is possible only by means of the Elster basic certificate. Authentication by means of the ElsterSpezial security stick or the ElsterPlus signature card does not work until further notice for technical reasons. You should request the Elster basic certificate from Elster. It is free of charge. The user will receive an encrypted certificate file in .pfx format to save on his or her computer. In addition, the user will receive a PIN by post.
