ELSTER Developer-ID

To transmit tax data through ELSTER a five-digit developer ID is required.

If not done already, a developer ID should be requested. This is done in two steps:

1. Register as a developer (in order to access the developer area) https://www.elster.de/elsterweb/registrierung-entwickler

2. Apply for a developer ID after login in the developer area https://www.elster.de/elsterweb/entwickler/antrag-hersteller-id​
