I’m not really sure what you are trying to explain.
I don’t really understand how a LLC is a form of investment. Please elaborate more on this.
You don’t need to hire employees. You can either employ yourself, or you are creating a so-called Sitzgesellschaft (no employees). I’m just wondering how do you want to receive dividends. Where is the money coming from?
You still have to send an annual balance sheet to the tax authorities. There is no grace period for new companies, just the option to prolong your business year (e.g. starting a company today (20.09.2021), you can prolong your business year until 31.12.2022)
That could lead to problems with Scheinselbständigkeit. Better to have at least two different customers.
Please note that owning a LLC/GmbH comes with costs attached. You need to put 20k down initially, then register the company, if you have an operating company (at least one employee) you need to pay AHV, UVG, BVG and liability. If you have a Sitzgesellschaft, you will pay more for your bank account (banks are charging more for that).
