Hello, I am Keith, one of the experts on Just Answer, and happy to help you with your question.
Sorry, the Just Answer system has lost my entire answer and I will have to write it again.
Yes, it is clear. Your French residence appears to be your sole or main domestic residence so any gain made on its disposal is not subject to UK CGT. French CGT is relatively low, the worst is 6% on any gain over 25 K Euros. I cannot go much further on French taxation as their system is so complex and so constantly changing that the employment of a local professional is essential. HMRC does not like the legislative definition of 'sole OR main domestic residence' and always tries to interpret to 'or' as 'and;' Watch out for this trick!
If your employer is requiring you to perform 75% of your duties in the UK you will almost certainly be spending over 183 days in the country in any one tax year and thus liable to UK taxation on your world wide income.
I would love to be able to talk to you on the phone, but I am answering your question from a time zone 6 hours ahead of the UK which will make that option a tad expensive!
I do hope that you have found my reply of some assistance.
As far as UK taxation is concerned you sole or main domestic residence escapes UK CGT. So there seems little point in tying to become non resident. You could do this through the Form P85 procedure, but once you have done this you can only spend 91 days in the UK in any one tax year to retain that status. Remember that these days the UK is beginning to be considered a tax haven!
Please be so kind as to rate me before you leave the Just Answer site.
Thank you for your support.
