Thanks for your replyYou will charged 40% emergency tax for the UK lump sum. You will then have to put in a tax claim to HMRC for any tax due back to you. It will depend on your present earnings, tax bands etc. If the pension lump sum is large you should consider doing a partial withdrawal to minimise tax due.
Is a lump sum from a UK pension taxable in Ireland. I returned to Ireland and my pension pot is still in the UK. I know I cannot moved the fund to Ireland.
