Tax system mismatchCritical

Sao Tome and Principe and Italy tax all worldwide income once you become a tax resident (top rate: 43%). Switzerland does not - only locally-sourced income is taxed. This is a fundamental structural difference that affects your total effective tax burden.

Exit tax applies in one jurisdictionCritical

Ireland has an exit tax. If you establish residency and later wish to leave, you may owe tax on unrealized gains or assets at departure. The other countries in this comparison do not have an exit tax.

18pp personal tax rate spreadNote

Both countries tax worldwide income, but the top personal income tax rates differ materially. Italy: 43% vs Sao Tome and Principe: 25%. Both apply to all global earnings once you establish residency.

CFC rules apply in one jurisdictionReview

Ireland and Switzerland and Italy have 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.

Not tax advice. Tax laws change frequently. Verify with a qualified professional before making residency decisions.
