Two questions hide inside one search
HMRC's starting point is that you usually pay tax on UK income even when you are not UK resident, and pensions are on its list. If the pensions article of the treaty with your new country gives that country the taxing rights, you claim on form DT-Individual. For most countries the form goes first to the tax authority where you live, which certifies to HMRC that you are resident there within the meaning of the treaty, and then on to HMRC. Residents of the UAE, Qatar, Bahrain and Saudi Arabia follow a different route in HMRC's notes: a residence question answered on the form itself, plus a copy of the local residence certificate or permit. HMRC can then grant relief at source, so no UK tax is withheld from the pension (in practice the NT code its PAYE manual gives a pensioner who has left for permanent residence in a treaty country), and it arranges any refund of PAYE already taken. One timing trap: the form says you can only apply for relief on pensions once the payments have begun. The second question, whether your new country taxes the pension under its own law, is for that country's tax authority and a local adviser. Our answers on whether a UK pension is taxed when you retire abroad and on getting an NT code for a pension paid abroad cover the mechanics.
What the treaty texts actually say
The list above is taken from the pensions article of each treaty as published on GOV.UK, and each of the seven that has one makes it subject to the government service article. Two things in the wording matter. First, Qatar, Bahrain and Malta restrict the article to pensions paid in consideration of past employment, and HMRC's DT-Individual notes say that where an article is restricted that way the State Pension can only be exempted under the treaty's other income article, and not at all if there is none. Second, Thailand has no pensions article and no other income article either, so nothing in the treaty takes a private pension out of UK tax, which is why our Thailand guide tells retirees to take both UK and Thai advice. The Cyprus position, including the Cypriot side, is in our guide to retiring to Cyprus from the UK, and the UAE, Portugal and Malta guides cover those destinations.
The two standing exceptions
Government service pensions first. GOV.UK says most UK government pensions, such as civil service pensions, are only taxed in the UK, and HMRC's DT-Individual notes confirm that under many treaties the UK retains primary taxing rights over a government pension. If that is you, the treaty does not move the pension, and the question becomes whether you can still claim UK personal allowances against it. The State Pension runs the other way. Non-residents do not usually pay UK tax on it, HMRC classes the National Insurance retirement pension as a non-government pension for treaty purposes, and it is usually paid without deduction of tax in any event. The country you live in may tax it instead, and whether it rises each year depends on where you live, which our State Pension abroad guide sets out.
What Horizon does
A pension-abroad review confirms, in writing, which article of your treaty each pension falls under, whether the State Pension is caught by the past employment wording, what stays UK-taxable, and the DT-Individual claim timed around your first payment. Fixed-fee advisory work from £550. That is the total, agreed before any work starts. If you keep UK income after you leave, a government pension, rent or a final split-year return, the Non-Resident and Expat Tax Return is £750 fixed, SA109 residence pages included. Nothing is added to either figure. The place to start is a free clarity call: tell us the country and the pensions, and you leave knowing which of the two questions actually applies to you.
