In den letzten Jahren habe ich mir immer Sorgen um Steuererklärungen gemacht.Ich musste alle Dokumente sammeln, die zu jemand weitergeben, damit er sie ausfüllen kann.Als ich ein Dokument vergaß, musste ich hin und her gehen, um es ihm zu geben. Es war alles Zeit- und Geldverschwendung.Aber dieses Jahr hat sich das geändert.Mit cotax habe ich alle Dokumenten innerhalb von 7/8 Minuten fotografiert und verschickt, und alles war in nicht mehr als 24 Stunden erledigt. Diesen App würde ich dringend empfehlen.
