CFC rules apply in one jurisdictionReview
Switzerland has Controlled Foreign Corporation (CFC) rules. Owning a foreign company as a resident may trigger local tax on undistributed profits - even if the company pays no dividends. The other country in this comparison does not have CFC rules.
Special tax regime available in one jurisdictionNote
Switzerland (Lump-Sum Taxation (Forfait / Expenditure-Based Taxation)) offers a qualifying program that may exempt foreign-source income from local tax. This can significantly reduce your effective rate compared to the standard regime.
