Digital application processes

Submit applications for withholding tax reclaims digitally

with the STTI interface

Claiming authorities are digitising their processes

The submission of physical forms is being replaced by new digital procedures.
Switzerland requires only the digital transfer of all information and documents for applications from Germany from the 2020 revenue year onwards. The fiscal authority in Germany is also developing a new interface.

Austria, Denmark and the Netherlands require data to be transferred via web interfaces. Financial institutions must prepare themselves technically for these new procedures.

Submit applications digitally or automate the filling of web forms

The interface STTI (secure transport of tax information) enables the secure transmission of tax-relevant information between internal systems of banks and claiming authorities.

No matter which application procedure is required, the interface supports the electronic submission of forms or transfers data to the required web form.

Data transfer between banking system and claiming authorities


Provide withholding tax service to all clients also in the future - regardless of the required application procedure

Paper-based applications will gradually be replaced by new automated application processes. What is a great advantage for claiming authorities, means a high technical effort for banks.

The STTI interface takes over all these tasks. This allows banks to offer their customers the service of withholding tax reclaim even for countries with digital application procedures.

Easy integration into processes

For automated process steps, the interface can be linked to any existing system. STTI is based on standard formats and can be technically connected everywhere.

Use for several countries

Via the interface, data can be communicated with different claiming authorities without having to worry about specifics of the respective systems and technologies.

Uniform data exchange

The system offers a uniform interface in terms of technology and data format. Internal systems only need to be coupled once, so that integration efforts are drastically reduced compared to a direct coupling with each claiming authority.

High security & compliance with data protection

The banking sector requires a high level of protection. This is ensured by encrypted data transmission, storage and access control mechanisms. As soon as an application process is completed, all data protection-relevant information is deleted; non-data protection-relevant information is retained for traceability.
