Having read many of the posts that deal with the issues of being resident in France but working for a UK-based company I am still not sure what my tax and social charges liability would be as well as that of my employer. I will work for a UK company and split my time working in both countries - from home in France for my employer's UK clients and on these client's sites in the UK. I have consulted an French-based accountant who is also a CA in the UK and he did not clarify this point. Instead he replied with this - "I copy below from my consultation: As a French resident you will be taxed on your income from the UK company, both that income earned while working from home in France, and the income from working in the UK. Social charges are payable on most types of income in France, including employment income. However as these are deducted as source, they would not apply to your income from the UK and you would therefore not be chargeable. You can ask your employer not to deduct NI from your salary on the basis that you are no longer resident in the UK. It will ultimately be up to the NIC contributions office if they accept this or not."
