Foire aux questions

Warum werden auf meiner Rechnung trotz Mehrwertsteuersenkung 19% ausgewiesen?

Bei Subskriptionen handelt es sich um sogenannte "Dauerleistungen".
Der Mehrwertsteuersatz für Positionen mit einem Leistungszeitraum (sog. Dauerleistungen) hängt vom Ende des Leistungszeitraums ab, nicht vom Rechnungsdatum. 

Schließen Sie also beispielsweise am 02.07.2020 einen Jahresvertrag (Subskription) ab, und die Mehrwertsteuer wird am 01.01.2021 wieder auf 19% angehoben, fällt das Leistungsende in die Periode von 19 % MwSt. Dadurch werden 19% fällig.

Sofern das Ende Ihres bestehenden Vertrages zwischen 01.07.2020 und 01.01.2021 liegt, werden bei monatlichem Zahlungsintervall bereits heute 16% ausgewiesen. Bei jährlichem Zahlungsintervall erhalten Sie am Ende der Vertragslaufzeit eine Gutschrift über die zuviel bezahlte Mehrwertsteuer, anteilig vom 01.07.2020 bis zum Enddatum Ihres Vertrages.
