Built around the German tax return
The service is designed for the annual German tax return and also covers the salary tax return, known in German as Lohnsteuererklärung. Filing happens through an online tax interview that asks questions one step at a time. Each step of the interview uses plain German language, so the wording does not require prior study of tax rules. Helpful tips appear during the process, and personal support is available from real people if a question comes up.
