About wundertax.de

wundertax provides an online application for preparing and filing German income tax returns (Steuererklärung) and property tax returns (Grundsteuererklärung). Users answer an occupation-specific interview, see a live estimate of their refund, and submit the return to the Finanzamt through the official ELSTER interface.

The service targets private taxpayers, including employees, self-employed people, students, expats, pensioners, police officers and Bundeswehr soldiers. Preparing the return is free; users pay only when they submit it, with a single return priced at 34.99 € incl. VAT, packages for three or four returns, and a joint assessment option for married couples and registered partnerships.

The company was founded in 2015 as "Study clever" for students and renamed wundertax after extending its concept to other target groups. It operates from an office in Berlin-Prenzlauer Berg, has a team of 22 people, and states that it has more than one million customers.

Product: Online tax return (Steuererklärung) and property tax return (Grundsteuererklärung) preparation and electronic filing via the official ELSTER interface.
