Tax system mismatchCritical
Sao Tome and Principe taxes all worldwide income once you become a tax resident (top rate: 25%). Portugal 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
Portugal 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 country in this comparison does not have an exit tax.
23pp personal tax rate spreadReview
Both countries tax worldwide income, but the top personal income tax rates differ materially. Portugal: 48% vs Sao Tome and Principe: 25%. Both apply to all global earnings once you establish residency.
CFC rules apply in one jurisdictionReview
Portugal 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
Portugal (IFICI (Incentivo Fiscal para a Internacionalização de Competências e Investimento)) offers a qualifying program that may exempt foreign-source income from local tax for up to 10 years. 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.
