WISO Steuer
WISO Steuer · Neunkirchen, Germany · founded 1986
What it is
WISO Steuer guides users through preparing and filing German income tax returns, with electronic submission to the tax office through the official ELSTER interface. It can recognize information from photographed wage statements and receipts, retrieve tax data such as wage-tax information with the user's consent, and update an expected refund estimate as details are entered. SteuerGPT answers tax questions in natural language. Tax Banking can retrieve and categorize bank transactions, but requires a finanzblick account. One license covers up to five returns, and the product is limited to people with unlimited tax liability in Germany. It is available on Android, iOS, Linux, macOS, web and Windows. The free test version allows all functions to be tried, with payment requested when submitting a return. The Vorteils-Abo is €35.99 a year and renews automatically each November; Einzelkauf is €45.99 a month. Buhl says data is stored on servers in Germany and uses HTTPS and AES-256 encryption for transmission and storage.
