Writing in a new thread, I know it's been discussed but can't find a specific-case one. So basically I filed my taxes for last year (calendar year 2020) via Taxfix. I just received a notification that my statement has been assessed and now I have to pay almost 600€ as 'tax bill' instead of a return. I assume that this was because of the progression taxes tied to being on Kurzarbeit for most of last year. Was just wondering if I need to pay this amount immediately when I get my steuerbescheid on the mail, or is it possible to pay this in installment or a later date?
