Hello, I am Keith, one of thee experts on Just Answer, and pleased to be able to help you with your question.
When you left these shores for the Middle east did you submit a Form P85 to HMRC?
Once registered as non resident you can spend up to 91 days in the UK in any one tax year without breaching your status. The 91 days can be averaged out over four years so that should cover your UK stay if you go back overseas.
On return the split year principle applies, part non resident and part resident if you were returning full time. You are not taxable on your Middle East income including the pay off moneys.
I do hope that you have found my reply of assistance.
You do not need to. Having submitted a P85 you are classified as non resident. If you were in the UK for say 15 days in each earlier tax year then you have 91 - 15 = 76 days slack to cover those above the 91 for the stay involving your Father's demise.
Make sure you are not paid until you are out of the country again would be my advice! Remember you still have your personal allowance of 11K to offset any UK earnings.
Please be so kind as to rate me before you leave the just Answer site.
Well it would be liable to UK income Tax, but don't forget the personal allowance.
Thank you for your support.
