The electronic transmission of the advance VAT return from SAP Business One takes place with the help of the ELSTER add-ons. The prerequisite is a current version of this add-on and the maintenance of relevant company data:

- Company details such as name, address, Tax number (under Administration > Master data > Company details).
- tax code must be defined and assigned to tax declaration fields.
Preparation and utilisation:
- First time use: Accept licence agreement and submit declaration of participation (can only be printed out once).
- Create a tax report: Select period, tax code and create a tax return in the "Tax report" window.
- Error checking: Check report, incorrect documents prevent transfer.
Transmission of the pre-registration:
- Data such as company details and Tax number are taken over.
- Select the federal state and tax office, optionally activate "Corrected report" and "Offsetting required".
- Connection test ("Test run"), then transfer in "Live run" by clicking on "Send data".
Post-processing:
- the posting period of the reported period should be closed after transmission to avoid subsequent changes.
