If you have read some of the posts, you will know that they "trick" you, to believe the Swiss tax is sufficient, but they are not fully open that the double tax treaty means you will be paying full tax in your country of residence.
This is not true. They make it clear that it depends on your country of residence whether if you have to pay additional income tax there.
Also it is not true that double tax treaty means you will be paying full tax at home. It can mean that, but most of the time you do not have to pay tax at home. It depends on what is the content of the double treaty agreement between your home country and Switzerland. And it is not always the same.
