I tried…..
Depends how you do the 'living' in France. The tax could work… However the biggest problem is social security. In my sceanrio: Moved to france to live but tried keeping my salaried job in UK, with no need due to my job to be in France I needed to pay French social security and was not entitled to pay NI or to a reciprocal health care rights from the uK as I was living in France. I did it for 3 months or so, then the risk of illness etc made me formalise it as I have a family with me. My wife is fully working in the french system so my son was covered, but I was not.
To pay social security in France when working for a UK company is possible, but it will cost your employer huge amounts as it's more in France than the UK. So my decision, was to give up the salaried uk job, become a registered french liberal professional (self employed) and work for my old company as a subconsultant basis. Because I'm french self employed, IR35 does not come into it.
