Well, to start off. If one were to set up a GmbH and work from home, what is the best possible scenario for tax efficiency? Assuming that one needs all the usual to live ie. an apartment, transport, insurance and other items that can be lobbed onto the company bill so one can treat it as an expense etc.

How are these scenarios different in higher tax cantons and lower tax cantons? Perhaps this is too broad so maybe compare Zug with somewhere with higher taxes?

Maybe you can find a topic in the above mess to start with?

And, thanks for volunteering your vast knowledge for the benefit of all those who want to be more tax efficient!
