Investments and pre-arrival gains

Test an exemption before calculating a gain. The share participation and ten-year holding rules have exclusions, while acquisition-cost rules and any foreign exit charge need their own analysis. No universal personal arrival-date reset is established here.

Andorra’s personal and corporate CFC rules can bring controlled foreign income into tax without a distribution. Effective management is a separate route through which an entity may become taxable in Andorra.

Leaving a high-tax country may trigger valuation, departure returns, withholding or continuing residence tests. An immigration grant is not evidence that those obligations have ended. Keep the legal sequence and supporting dates consistent.
