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. ## Frequently asked questions about cotax ### How does cotax ensure the security of my financial documents?
