Tax system mismatchCritical

United Kingdom and Thailand and Sao Tome and Principe tax all worldwide income once you become a tax resident (top rate: 45%). Paraguay does not - only locally-sourced income is taxed. This is a fundamental structural difference that affects your total effective tax burden.

20pp personal tax rate spreadReview

Both countries tax worldwide income, but the top personal income tax rates differ materially. United Kingdom: 45% vs Sao Tome and Principe: 25%. Both apply to all global earnings once you establish residency.

CFC rules apply in one jurisdictionReview

United Kingdom 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 countries in this comparison do not have CFC rules.

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