If I managed to land the job
, it would then be very useful for me to avoid England's 40% tax
, not yet considering the cost of living
!
You don't pay 40% tax in the uk. Only the proportion of your salary above a certain level (36k ? can't remember) is taxed at 40%.
It's a completely different system than France.
Overall I reckon you would actually pay less in tax in the uk, but it is probably compensated by the fact that property is expenesive over here.
