Anyone here retired to the UK with a UN pension (or planning to)?

[ConfusedExpat1]

Hiya. My husband is 6yrs away from full UN pension age when we are planning to return to the uk. We've got the projections from the unjspf and starting to get a handle on what might look like after the UN (let's assume it doesn't collapse in the meantime).

For projection purposes I'm assuming that we get 10% of our yearly pension income tax free then the rest is treated as per UK pension income. If we take $100k as a lump sum do you know how that's treated for tax (will need it plus some if we want to keep dcs in the same school).
Would the lumps sum be tax free?

Im assuming that we will need a UK based financial planner to help us relatively soon but is that necessarily the case? Has anyone hear managed the move 'home' without help?

DH is the higher earner of us but thoroughly uninterested in finances so I'm trying to get my head around everything now I realise how quickly time is going!

Thanks to anyone with insights/experience to share/ good recommendations for a financial planner versed in this area.

I highly recommend you take advice from a suitably qualified tax adviser with experience of international tax legislation, specifically the UK-USA Double Taxation Agreement.
HMRC has in recent years recognised that UN pensioners should be entitled to a partial exemption from UK taxation on some of their UN pension for a specified number of years following retirement. The details regarding amount and duration are complex and vary according to age and individual circumstances, but are significant. You can obtain further information from the British Association of Former United Nations Civil Servants (BAFUNCS), including in relation to where to go for advice on making a claim.
You might also want to take into account the potential applicability of the recently introduced FIG Regime if you will have been in a DS outside the UK for more than 10 years.

Thanks so much for your reply. We've found an experienced tax advisor since my post as we realised it's all far more complicated than we could handle!
