The Swiss government offers the opportunity to become a tax resident of the country and pay taxes not on income received outside of Switzerland, but on expenses in the country. There is a lump-sum tax, the exact amount of which is calculated separately in each region and for a particular taxpayer.
The minimum tax is 250 thousand Swiss francs per year. It is fixed and does not change over time. In this case, it is important that this amount does not depend on your income, availability of funds in bank accounts or ownership of real estate outside of Switzerland. If you have any income in the country, it will also be taken into account in the taxation.
