Key figures — as of 2026-10-13: From 6 April 2027, most unused UK defined-contribution pension funds and death benefits will be brought into the value of an estate for UK inheritance tax, taxed at the standard 40% rate above the nil-rate band — spousal transfers remain exempt — GOV.UK; Royal London. Portugal's NHR closed to new applicants on 31 March 2025; the replacement regime, IFICI, excludes foreign pension income entirely, taxing it at ordinary progressive Portuguese rates. IFICI registration for anyone who became a Portuguese tax resident in 2026 must be filed via Portal das Finanças by 15 January 2027.
Two deadlines, one calendar year
Foreign retirees who settled in Portugal expecting the old tax-friendly arrangement are waking up to a double shift. On the Portuguese side, the generous Non-Habitual Resident regime that once let qualifying pensioners pay a flat 10% (or in the earliest years, nothing) on foreign pension income is gone for new arrivals — NHR stopped accepting new applicants from 1 January 2024 and the transitional registration window has since been exhausted, replaced by IFICI, widely called NHR 2.0. The problem for retirees specifically: foreign pension income under IFICI is not covered and is taxed at standard progressive rates, not the flat concession NHR once offered.
On the UK side, the Treasury is closing a different gap. From April 2027, pensions will no longer be exempt from inheritance tax, meaning inheritance tax may have to be paid on a pension when the holder dies. The change is now law: the Finance Act 2026 is now law, and the changes to inheritance tax on pensions will take effect from 6 April 2027. Crucially, pensions left to a surviving spouse or civil partner will still benefit from the spousal exemption, while pensions left to children or other beneficiaries will face an IHT charge, and pension savings could now be subject to IHT at 40%, significantly increasing the taxable value of an estate.
For a British retiree who moved to the Algarve or Lisbon on the strength of NHR, both pillars of their original plan — the Portuguese tax break and the UK pension shield — have effectively disappeared within the same few years.
Why advisors are telling clients to act now, not in 2027
Financial advisors serving the expat community say the overlap is the real story: it's not one change but two converging at once. A pension pot that sat quietly outside both the UK estate and the Portuguese tax net is now exposed on both fronts — taxable as income in Portugal during life, and taxable as part of the estate in the UK at death.
GrowIN Portugal's analysis: take a retiree with a £400,000 defined-contribution pension pot and no other IHT planning. Against the standard £325,000 nil-rate band, roughly £75,000 of that pot would sit above the threshold once pensions come into scope from April 2027. At the standard 40% rate, that's approximately £30,000 that moves from heirs to HMRC — money that, under the old rules, would have passed outside the estate entirely. Scale that across a pension of £600,000–£800,000, common among long-serving UK private-sector retirees, and the number climbs into six figures.
"Retirees who built their move around NHR now need two separate conversations — one with a UK pensions adviser, one with a Portuguese tax specialist — because neither rulebook looks like it did when they packed their boxes," says GrowIN Portugal Editorial.
What's actually changing, and what isn't
It's worth being precise about scope. Death-in-service lump sum benefits will be excluded from the changes, including for non-active members, and benefits passing to a registered charity will also be exempt. The UK reforms target unused pension wealth passed to non-spouse beneficiaries — typically adult children — which is precisely the scenario many retirees in Portugal had structured their estate planning around.
On the Portuguese side, IFICI was never built for retirees in the first place. It targets skilled employment and self-employment income tied to innovation, research and specific qualifying activities — not passive pension income. Anyone who became Portuguese tax resident during 2026 and might qualify under one of IFICI's narrow routes (a working spouse in a qualifying profession, for instance) needs to file via Portal das Finanças by 15 January 2027; missing that date generally means losing a year of the ten-year benefit window.
Practical implications
For couples, the UK spousal exemption still offers breathing room — nothing changes on the first death if everything passes to a surviving spouse. The exposure bites on the second death, or for single retirees, or where pensions are earmarked for children. Options advisors are discussing include drawing down pensions earlier (accepting income tax now to shrink the estate later), restructuring via trusts where appropriate, reviewing beneficiary nominations, and — for those still weighing the move — reconsidering timing of Portuguese tax residency against both the IFICI deadline and the April 2027 UK change.
None of this is a substitute for regulated advice. Outcomes depend on individual circumstances, scheme rules and decisions still pending from HMRC guidance due ahead of implementation. Anyone with meaningful pension wealth and a move to Portugal already made — or planned — should be talking to both a UK-regulated pensions adviser and a Portuguese tax specialist before year-end, not after the rules take effect.

The nine-month gap between now and 15 January 2027 is the realistic planning window — after that, both calendars start running against retirees rather than for them.
