Tax is usually the question underneath every other expat pension question – how much you’ll actually keep once income starts flowing. Here’s how UK pension tax works once you’re no longer UK tax resident.
Establishing Your Tax Residency First
Before any of this applies, you need to know whether you’re actually UK tax resident or not – determined by the UK’s Statutory Residence Test, which weighs days spent in the UK, ties such as family and property, and your residence history, not simply where your address happens to be. Getting this wrong at the outset undermines every calculation that follows, so it’s worth establishing definitively before assuming non-resident tax treatment applies to you.
The Default: UK Tax Deducted at Source
UK pension income is normally paid under PAYE, with UK tax deducted at source by the scheme administrator before it reaches you – this happens by default, regardless of whether you’re UK resident or not, unless you’ve specifically arranged otherwise. For many non-residents, this means UK tax is being withheld on income that may actually be taxable in their country of residence instead, under a double taxation agreement – which is where things can go wrong if left unaddressed.
Claiming Relief Under a Double Taxation Agreement
The UK has double taxation agreements with a large number of countries, many of which allocate taxing rights over pension income to your country of residence rather than the UK. Where this applies, you can generally apply – using form DT-Individual or the equivalent process for your country – to have UK pension income paid gross, without tax deducted at source, so it’s taxed once, in your country of residence, rather than twice. This isn’t automatic; it requires an active application, and processing can take some months, so it’s worth starting well before you plan to begin drawing income.
The 25% Tax-Free Lump Sum
Non-UK residents generally retain access to the standard 25% tax-free pension lump sum in the same way UK residents do, up to the Lump Sum Allowance of £268,275. This is a UK tax-free treatment specifically – whether your country of residence also treats it as tax-free is a separate question entirely, and not every country mirrors the UK’s treatment. Some countries tax UK pension lump sums as ordinary income locally even though the UK itself doesn’t tax them – worth checking specifically for your country rather than assuming UK tax-free automatically means tax-free everywhere.
How This Differs Between a SIPP, QROPS and the State Pension
A UK SIPP follows the non-resident tax treatment described above, governed by whichever double taxation agreement applies. A QROPS moves the pension outside the UK tax system into its new jurisdiction’s tax treatment, which can differ meaningfully – part of why jurisdiction choice matters so much for a QROPS. The State Pension is taxable income in the same way as other pension income, though because tax is generally not deducted at source on the State Pension itself, it usually needs to be declared and taxed through your country of residence’s own tax return process, or via UK self-assessment if you retain any UK tax liability.
Why Getting This Wrong Is a Real Cost, Not Just an Admin Headache
Failing to address non-resident tax treatment properly doesn’t just risk being taxed twice temporarily – reclaiming overpaid UK tax after the fact can take months, sometimes longer, and ties up money that should have been available to you from the outset. Getting this set up correctly before income starts flowing is considerably easier than untangling it retrospectively.

Frequently Asked Questions
Will UK tax automatically be deducted from my pension once I move abroad?
Yes, by default, unless you specifically apply for it to be paid gross under a double taxation agreement.
Is the 25% tax-free lump sum always tax-free wherever I live?
It’s tax-free under UK rules, but your country of residence may tax it differently – worth checking specifically for your country.
How long does it take to arrange gross payment under a double taxation agreement?
Processing can take several months, so it’s worth applying well ahead of when you plan to start drawing income.
