How does French CGT tie in with UK CGT?
It is likely that French CGT will be nil or far less than UK CGT. There are other French CGT exemptions for instance for landlords of furnished properties who have owned them for five years. You are taxable in the UK on any French gain if you are resident or ordinarily resident in the UK. There are exemptions from UK CGT for non-UK domiciled individuals who do not remit the sale proceeds to the UK. Similar planning incidentally applies to avoiding UK income tax on the rental income from the French property. Tax planning for UK investors who have seen sharp rises in French property over the last few years focuses on avoiding or mitigating the UK liability.
