Recording of the data transmitted via the Internet with MAGPIE tax data to be transmitted.
The ELSTER protocol (electronic tax return) is available in SAP Business One for certain localisations and enables companies in Germany to efficiently transmit tax data to the tax authorities.

Functions and advantages of the ELSTER protocol
The ELSTER procedure is based on the Tax Amendment Act of 2003 and concerns two central business areas:
- finance: Advance sales tax returns
- Human Resources: Income tax declarations and certificates
Since 1 January 2005, it has been a legal requirement to transmit these reports electronically to the tax authorities' clearing office. With the integration of the ELSTER add-on, SAP Business One offers a convenient way to fulfil these requirements directly from the system.
Requirements for using the ELSTER integration
In order to use the ELSTER add-on successfully, the following conditions must be met:
- A current, compatible version of the ELSTER add-on (updated annually by SAP)
- A stable internet connection
- SAP S-User access for downloading updates
The regular provision of new add-on versions takes tax law changes into account and ensures conformity with legal requirements.
Functionality and special features of the ELSTER add-on
The following steps are required after installing the add-on:
- Initial configurationWhen starting for the first time, the system displays the licence agreement for the ElsterTelemodule. After confirmation, the user name and date are saved.
- Declaration of participationPrint out the one-off ELSTER declaration of participation and send it to the relevant tax office.
- Notifications and correctionsTax reports can be called up, changed and resent at any time if required. To do this, activate the field Corrected message.
Extended functionality and flexibility
The ELSTER integration not only enables the electronic transmission of advance VAT returns, but also the adjustment and resubmission of reports. This is particularly helpful for subsequent corrections.
In addition, the ELSTER solution works seamlessly with other SAP Business One functions to increase compliance and efficiency in accounting.
