Legal entities that are resident in Switzerland may apply for a refund of the withholding tax electronically using the Form 25.
In order to be able to reclaim the withholding tax, the company is required to fill out a claim form which will be sent to the Federal Tax Administration. The novelty is that this application and all necessary documents may be sent online. A signature in paper form must be delivered for reasons of legal certainty.
Tax partners are able to view all their data online and edit it. In addition, companies can empower trustees or their employees.
