Tax system mismatchCritical

Spain and Argentina tax all worldwide income once you become a tax resident (top rate: 47%). Switzerland and Portugal do 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

Spain and Portugal have 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.

13pp personal tax rate spreadNote

Both countries tax worldwide income, but the top personal income tax rates differ materially. Portugal: 48% vs Argentina: 35%. Both apply to all global earnings once you establish residency.

Special tax regime available in one jurisdictionNote

Switzerland (Lump-Sum Taxation (Forfait / Expenditure-Based Taxation)), Portugal (IFICI (Incentivo Fiscal para a Internacionalização de Competências e Investimento)) offer 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.
