Well, no initial balance sheet required. Taxes are filed, of course. VAT had to be decleared, in theory, every month. You get reminders, so it can also be done for multiple months. Now, due to lack of revenue, I have to file a zero VAT declaration quarterly. And your deadlines are longer than if you eork with a registered tax advisor. That's why I said so far, I'll have to do all that this year, the 2021 balance sheet is due in 2023, no need to publish the latest in the Bundesanzeiger anyway. After all, that's par of the course of doing proper business, and cost of doing business.
