My wife and I live in Lebanon (she is dual national), and have done since I retired in 1997.I receive a pension from Mobil Oil directly into my bank account in the Channel Islands;I have a notification from the inland revenue confirming this pension is non-taxable.( I never worked for Mobil in the UK). I have no other income which could be construed as UK-sourced income.
My uk state pension began when I reached 65 (2006).
In your 2nd para you suggest my Mobil pension is taxable in the UK; the inland revenue declare it non-taxable.
I do apologise. I wasn't suggesting it was taxable. I simply missed the word "not" in my answer. The line should have read "given that you say that your Mobil Oil pension is not taxable in the UK and would not, therefore, use your personal allowance.
