Hi. I am a freelancer in Germany and it's going to be my first time to claim to the German tax office.
As I am a Kleinunternehmer, I think I need to state the following sentence on each invoice.
'Als Kleinunternehmer im Sinne von § 19 Abs. 1 UStG wird Umsatzsteuer nicht berechnet.'
But it seems like there is no such function!
Please, someone tell me what can I do. Should I reissue invoice to Upwork(I'm not sure if it's possible to do it)?
(my VAT number is registered at Upwork)
