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.

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

Ireland and United Kingdom 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 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.
