UK Pensions and Inheritance Tax: What Australian Residents Need to Know Before 2027

For many Australians who still hold UK pension pots, these assets have long been treated as a quiet, tax‑efficient corner of their financial world — something to deal with later, once everything else was settled.

That assumption is about to change.

From April 2027, UK legislative changes will significantly alter how UK pensions are treated on death. For Australians who still hold UK pensions, this is no longer a technical footnote — it is a material estate‑planning issue that deserves attention well before the rules take effect.

The short version

For Australian residents who still hold UK pensions:

• From 6 April 2027, most unused UK defined contribution pension balances will be brought into the UK inheritance tax (IHT) net — even if you live in Australia.
• Whether UK inheritance tax applies depends heavily on your UK residency history, not just where you live today.
• For many former UK residents, their UK pension may now be one of the largest remaining UK‑taxable assets.
• By contrast, Australian superannuation is not subject to UK inheritance tax, meaning UK pensions now carry greater estate risk than comparable Australian structures.

What exactly is changing?

UK pensions will no longer sit quietly outside the estate

Historically, most UK defined contribution pensions — such as personal pensions, SIPPs and workplace pensions — sat outside the UK estate for inheritance tax purposes. This made them a particularly effective estate‑planning tool.

That changes from 6 April 2027.

From that date:

• Unused pension funds and most lump‑sum death benefits will be included when calculating UK inheritance tax
• The standard 40% inheritance tax rate applies above the available nil‑rate band (generally £325,000, plus any applicable spouse reliefs)
• This treatment applies even if the pension holder lives outside the UK, including in Australia

This change is now legislated and confirmed.

Residency history now matters more than where you live today

Another significant change — already in effect — is how the UK determines who is exposed to inheritance tax.

From 6 April 2025, the UK replaced its long‑standing “domicile” framework with a residency‑based system.

Under the new rules:

• You are treated as a long‑term UK resident if you were UK tax‑resident for 10 of the last 20 tax years
• If that threshold is met, your worldwide estate, including pensions, can fall within UK inheritance tax
• Even after leaving the UK, a tail period of up to 10 years can apply, during which exposure continues

If you do not meet the long‑term residency test, only UK‑situ assets are exposed. From 2027, UK pensions themselves are explicitly treated as UK‑situ assets, which is why Australians who left the UK many years ago may still be affected.

What this means in practical terms for Australians

Living in Australia does not automatically protect your UK pension

Even if:

• You are an Australian citizen
• You have lived in Australia for decades
• Your beneficiaries all live in Australia

Your UK pension can still attract UK inheritance tax if:

• You fall within the 10‑out‑of‑20 residency test, or
• The pension is taxed as a UK‑situ asset under the new rules

This often comes as a surprise to people who reasonably assume they have long since exited the UK tax system.

UK pensions can now be taxed in two different ways

Australia does not impose inheritance tax — but that does not mean UK pensions pass cleanly to Australian beneficiaries.

In practice:

• The UK inheritance tax charge applies first, before funds leave the UK
• Amounts received by Australian beneficiaries may still be assessable for Australian tax purposes, depending on structure, timing and beneficiary status

This creates a one‑way tax drag that does not exist for Australian superannuation.

---

The type of pension you hold matters

Not all UK pensions are affected equally.

• Defined contribution pensions (SIPPs, personal pensions, most workplace schemes) are most exposed
• Defined benefit pensions that pay an ongoing spouse’s pension often have no capital value and may be sheltered by UK spouse exemptions

Most Australian residents with UK pensions hold the first category — which is why this change is particularly relevant.

---

Why this is strategically important from an Australian perspective

Viewed through an Australian planning lens, the contrast is becoming clearer:

• UK pensions (from 2027) can attract UK inheritance tax of up to 40%, and may still be taxed when received in Australia
• Australian superannuation does not attract UK inheritance tax, and typically passes to spouses or dependants with little or no tax
• Non‑UK investments sit somewhere in between, depending on structure

Leaving pensions in the UK is no longer just about convenience, currency or familiarity. It is now a legislative risk that needs to be actively considered.

---

What many people are now reviewing

This isn’t about reacting in haste — but it is about being deliberate.

Common review points include:

• Whether UK pensions should remain in the UK at all
• Timing of withdrawals versus transfers
• How UK outcomes interact with Australian superannuation death‑benefit rules
• Whether exposure can be reduced before the April 2027 deadline

The UK reforms themselves acknowledge that these changes fundamentally reshape cross‑border pension and estate planning.

The key takeaway

For Australians with UK pensions, the ground has shifted.

Assets that once quietly supported long‑term estate planning may now create unexpected inheritance tax exposure. The change is confirmed, dated and structural — and it applies regardless of where you live today.

If your UK pension hasn’t been reviewed recently, now is the right time to revisit how it fits into your broader strategy.
