At the Swiss federal floor of CHF 435,000, the lump sum is cheaper on the model: $84K to $150K a year against $330K in Italy.
Italy becomes cheaper once the Swiss deemed base passes about CHF 1,342,000 in Zug or CHF 799,000 in Geneva, which a large home can push it to through the 7 times rent rule. Italy also exempts foreign assets from wealth tax, and Switzerland does not.
It is ordinary tax on a deemed base of at least CHF 435,000, 7 times the rent, or actual living costs, whichever is highest. On the model that is $84K to $150K a year at the floor.
