Tax free under UK rules, subject to the £268,275 lump sum allowance. Whether it is tax free where you now live is an entirely separate question — and the answer is often no.
The pension commencement lump sum is one of the most valuable features of the UK pension system: broadly a quarter of the pot, paid free of UK income tax, capped by the £268,275 lump sum allowance. It is also one of the most misunderstood by people who take it after emigrating, because "tax free" describes the UK treatment only.
Many countries have no equivalent concept. To them, a payment out of a pension is pension income, and the fact the UK chose not to tax it is irrelevant. If you are resident there when you take it, you may face a full local charge on a payment you were expecting to receive clean.
Residence at the Point of Payment Decides It
The critical date is when the lump sum is paid, not when the pension was built or when you left. Take it while UK resident and the UK exemption applies to a UK-resident taxpayer, which is the straightforward case. Take it after becoming resident elsewhere and your new country's rules apply to the receipt, with the treaty determining who has the taxing right over pension payments.
| When taken | UK position | New country position |
|---|---|---|
| While still UK resident | Tax free within the allowance | Not yet relevant |
| After becoming non-resident | Still outside UK income tax | Depends entirely on local law and the treaty |
| In a split year, overseas part | Care needed — check the split date | Likely the local rules apply |
| Where the treaty gives the UK sole rights | UK rules govern | Usually reportable, sometimes exempt |
Some treaties handle this explicitly and some do not. A minority contain wording that preserves the exempt character of a lump sum that would be tax free in the source state. Most do not, and where they are silent the local domestic rules generally win. This is the single most valuable thing to check before you fix a retirement date.
Why This Is Not Just a Rate Question
A lump sum is by definition a large payment in a single year. In a country with progressive rates, receiving it all at once can push the whole amount through top brackets, producing an effective rate on the payment far above the headline rate on your ordinary income. Countries that would tax a modest annual pension lightly can tax a single large withdrawal heavily. Spreading withdrawals over years is often worth more than any rate arbitrage between the two countries.
The Sequencing Question
This turns the decision into one about ordering rather than about pensions. If the lump sum is materially better treated in the UK, taking it before the residence change is the obvious answer — but that has to be weighed against taking a large sum earlier than you need it, losing the tax-free growth it would have enjoyed inside the wrapper, and possibly triggering the £10,000 money purchase annual allowance if you also start drawing taxable income. Our guide to split-year treatment explains how the split date is fixed, which is exactly the date this decision turns on.
The Rest of the Pot
The taxable 75% follows the normal treaty rules for pension income. Where the treaty gives the taxing right to your country of residence, HMRC can issue an NT tax code so the payments come through without UK deduction. Without one, PAYE runs and you reclaim — a cash-flow cost that compounds over a retirement. Our retiring abroad guide covers the wider picture, including the State Pension.
Get This One Checked
Very little on this site warrants a recommendation to pay for advice. This does. The sums involved are large, the decision is irreversible once the payment is made, and the answer depends on a specific treaty article and a specific country's domestic law rather than on any general principle. See choosing an expat tax adviser for what to look for, and note that you want someone who can read both sides, not two specialists who each read one.
Frequently Asked Questions
Is my 25% tax-free lump sum still tax free if I live abroad?
Under UK rules the exemption stands, within the £268,275 lump sum allowance. Whether your country of residence taxes the payment is a separate question governed by its own law and the treaty, and many countries do tax it in full.
Should I take the lump sum before I emigrate?
Sometimes, but not automatically. It has to be weighed against taking money earlier than needed, losing tax-free growth inside the wrapper, and possibly triggering the money purchase annual allowance.
Does the double tax treaty protect the tax-free element?
Only where it says so. A minority of treaties preserve the exempt character of a lump sum from the source country; most are silent, and where they are silent local domestic rules usually apply.
Is it better to take smaller withdrawals instead?
Frequently, yes. A single large payment can run through the top brackets of a progressive local system, so spreading withdrawals often saves more than any difference in headline rates between the two countries.
