What I meant was your recommendation of “incorporate in Nidwalden and pay for some substance, then live in another canton.”
Once you add the substance costs, those 2% may quickly seem cheap. And I guess even within Switzerland, there is a risk that your home canton may require proof that you’re not secretly running the company from where you live. So for just 2%, this seems like not such a good idea. If you live in Zurich or Bern, it may be different. So it would all depend on where you want to live, but as you can see, many municipalities are in the 12-14%︀ range.
But I guess the big savings lie in the fact that Switzerland doesn’t have︁ CFC rules as well as tax incentives (80% discount I think) for IP. The big︂ question is if you can set it up properly without paying through your nose, only︃ making it worthwhile for profits upwards of a couple million.
