A strong position in a demanding category
Tax software has to make complex decisions feel manageable. WISO Steuer – Steuererklärung earns a score of 78.2 in Germany’s banking and fintech app user satisfaction survey, the APS from Cassuarina Labs. This places the app in the Strong Zone, a range associated with high satisfaction and engagement, alongside an overall tendency toward loyalty and willingness to recommend.
Enthusiasm leads, with a smaller pocket of friction
Survey results show that 78.8% of respondents love the app, matching its reported Fans share, while 10.4% like it. Among dissatisfied respondents, 2.2% are disappointed, 2.4% are very disappointed and 6.2% are frustrated. The reported Critics share stands at 8.6%. The distribution points to a product that inspires considerable enthusiasm, although the most negative experiences deserve focused investigation.
Turning tax preparation into a connected workflow
WISO Steuer brings guided questions, automatic retrieval of tax information and continuously updated refund calculations into one workflow. Digital submission through ELSTER and access across smartphones, tablets and computers extend that convenience from preparation to filing.
Designed for a broad range of income situations, the German-language app also lets users prepare and check their return before paying to submit. These capabilities offer clear practical strengths: less manual entry, greater visibility during preparation and flexibility across devices. Their individual contribution to satisfaction would require feature-specific survey feedback.
The product lesson: make complexity easier to navigate
The opportunity lies in helping people understand what to do next and feel confident about their progress. WISO Steuer’s satisfaction profile suggests that its overall experience resonates with respondents. The next research priority is to understand where that experience breaks down for dissatisfied users—whether during data entry, explanation, payment or submission. Connecting those moments to targeted improvements would give the product team a concrete path toward broader satisfaction.

Refund estimates that undermine confidence: Some respondents report substantial differences between projected refunds and their final tax assessments, including unexpected payments due. These accounts do not establish what caused the discrepancies.
