I have recently started a new job outside of the UK since my last outfit went tits up and the number of UK pilots who are seeking non residency status, has never been higher than now, according to the chap I spoke to for tax advice.
I looked at a recent payslip when I was employed in the UK and as a jet skipper, my total PAYE tax per month was the same as my monthly salary when I started off as a turboprop F/O, nearly six years ago.
