Take a look at this site:
I am dealing with this subject myself but am in Baden-W羹rttemberg and every German State has its own rules. Here in BW anyway, the rules on the application for 蹙棗款棗娶喧堯勳梭款梗 have been changing daily since until now it has been unbelievably complex. Its confused how they will actually figure out how much one really gets and what proof is needed. The whole idea is that it should give money to save businesses or self-employed people threatened by imminent bankruptcy due to the Corona virus shutdown. This program is organized through the local Arbeitskammer.
Another possible help is Arbeitlosengeld II which is a social assistance given through the Job Center department of the Agentur f羹r Arbeit (Employment office). This doesnt look so directly at the business situation as much as it looks at ones personal existential needs like paying for rent, food, and utilities. One can get this even if they have work but dont make enough to survive. Usually one who has say over 8000 Euros (was this amount some years ago but I dont know the current limit) of financial assets does not qualify but there is supposed to be an exemption due to the Corona situation. What they arent going to cover are fixed business costs people might have.
And as far as I know one can only apply for either the 蹙棗款棗娶喧堯勳梭款梗 or the Arbeitlosengeld II but not both but even this is not certain at this point. Which one is more appropriate depends on ones individual circumstances and it nearly impossible to say at this time. I dont know for myself. I sent in the main application for Arbeitlosengeld II last week and got a envelope with 9 further forms consisting of about around 80 pages of requirements and questions that not only most Germans cant understand but even someone from the Arbeitsamt said he didnt understand! They ask about every little detail about your person, citizenship or residency status, accommodation, assets, debts, income, education, work history etc. About the only thing they dont require is a colonoscopy but I wouldnt be surprised if they added this to the list. One is supposed to hand in a mountain of documentation. I got German citizenship last year and didnt have a quarter of the requirements and forms to fill out.
So easy and quick help is it not. One needs help from a lawyer or the Job Center officials themselves but the offices are not open due to the shutdown and are flooded with applications. At least here one can eventually get someone on the phone for very basic questions. So dont expect that anyone here on this site can explain or help. That is like a kid asking someone to explain the details of theoretical physics. Possibly the 蹙棗款棗娶喧堯勳梭款梗 will be less bureaucratic but I would not hold my breath.
To add, 5 minutes ago I had another call to someone at the employment office and he claimed that from Thursday there should be new forms and rules mandated that should be simpler and I won't have to fill out all of the ones they sent me. It is a question of waiting and seeing as the situation is in constant change. He also said the "Soforthilfe" for my sitaution would not help much as I am losing all of my income but don't have real high fixed business expenses which is what they really look at.
