@nhkyn , Salam Aliquom
(a) Are you a US person ( citizen/GreenCard/ Resident for Tax purposes ) ? If not US citizen, then citizen of which country ? If you are on work visa -- Resident for Tax Purposes , which visa ?
(b) Your pension distribution you said is lump sum , does this mean a total distribution ? Why is the taxable amount different from gross distribution ? Is this because of your own contribution or what ?
(c) Was this your first year of pension -- is this because you are no longer a UK resident, because of age or what ?
(d) Are you currently in the USA or in the UK ?
I am trying to understand the whole situation, specifically for treaty considerations, taxability of the pension amount etc. Obviously and based on your answers, there may be more questions to answer.
I will circle back once I hear from you --yes ?
