Wundertax is a web app for preparing and filing a German income tax return online. It guides users through their tax case without prior tax knowledge, runs automatic plausibility checks, and shows the expected refund as they enter data. Returns go to the tax office through the official Elster interface. Users can start free and pay only when they file. Separate versions cover employees, self-employed people, students, expats, police, military and retirees. The company says it does not provide individual tax advice.
