Wundertax offers a smart and easy-to-understand online solution for filing tax returns. Whether employees, self-employed professionals, students, or expats: specialized tax tools optimally cover the needs of different professional groups.

Using a simple tax interview, the fintech helps its customers handle their taxes quickly and easily on their own and optimize their tax refund. The intuitive user experience makes filing a tax return a straightforward matter — without tax forms or expensive tax consulting.

Training all employees on data protection and raising their awareness is also close to wundertax's heart. As a user of the HR software Personio, wundertax was therefore looking for a data protection solution that would ideally allow a technical integration with Personio. Since working with third-party providers in turn requires special attention under data protection law, the company was in the right place with heyData in this respect as well.

As a startup dedicated to simplifying and digitizing taxes, wundertax wanted an equally simple and digital solution that bundles all data protection matters.

The Challenge

Data protection has been a top priority at wundertax from the very beginning. This applies to all data collected — from a one-time visit to the website to a customer's submitted tax return. After all, a tax return contains a person's most sensitive data. Whether tax ID, religious affiliation, union membership, or income: protecting and securing this data has been the company's focus since its founding.

A responsible approach to users' data also plays a major role in day-to-day business when it comes to data storage regulations and the associated retention periods. All work processes must meet current data protection requirements at all times — especially when it comes to customers' personal data in tax returns.

As the company's customer base grew, however, not only did the volume of data to be managed increase steadily, but so did customers' questions about the protection of their data. wundertax needed more and more resources for communication and longed for a time-saving solution.
