I left in 2003 and filled out the form and was NT No tax for many years until approx 2003 when I was put on emergency L1000 code for my private pension drawn in the UK (540 pounds a month), the residency criteria in UK changed around the same time.
I will lose my non residence when I return as I shall start work in the UK on 1st August. Is the money still free of taxation if I send it back before my arrival?
It is normal for pensions to be taxed in the country of origin, hence the issue of a tax code to collect tax thereon. However, as you pension aggregates to GBP 6480 pa, well below the Personal Allowance, no tax should be being deducted.
The pension does not affect your non residential status. You should ask HMRC why they consider you resident since the P85 proceedure should have settled that and the matter of a pension is an irrelenace. Literally tousands of ex pats have pensions taxed in the UK, yet are non resident. It sounds to me as if HMRC have been making assumptions. HMRC are very keen on these and in my experience their ideas are invariably wrong and always in favour of the Revenue.
The money you have saved in the Oman, as you are a non resident, is not taxable on repatriation to the UK. Your non residential status ends when you notify HMRC of your return as I explained in my original response.
Thank you for your excellent support.
