Tax Transfer DE will establish HTTPS connections to either datenannahme1.elster.de, datenannahme2.elster.de, datenannahme3.elster.de or datenannahme4.elster.de via Port 443 to communicate with the German Tax Authority.

Tax Transfer DE can be configured to use a proxy to communicate with the German Tax Authority.

Edit the appsettings.json file in the physical directory of the Tax Transfer DE application:

  1. Set "Application" > "Eric" > "ProxyHost" to <your-proxy-hostname-or-ipaddress>
    The SOCKS4 and SOCKS5 protocol without authentication is supported. The protocol name must precede the host name, e.g, socks4://example.proxy.com

  2. Set “Application” > “Eric” > “ProxyPort” to <your-proxy-port>

  3. Set “Application” > “Eric” > “ProxyUsername” to <your-proxy-username> if required by <your-proxy-hostname-or-ipaddress>

  4. Set “Application” > “Eric” > “ProxyPassword” to <your-proxy-password> if required by <your-proxy-hostname-or-ipaddress>

  5. Set “Application” > “Eric” > “ProxyAuthenticationType” to either "Any", "Basic", "Digest", "DigestIE", "NTLM", "SPNEGO"

Save your changes and restart the application, if it is already running.
