Guide To Labour Inheritance Tax Pension Changes: Protect Your Wealth From Double Taxation
The Labour inheritance tax pension changes, legislated through the Finance Act 2026, will bring most unused pension funds and pension death benefits within a deceased person’s taxable estate from 6 April 2027.
Until that date, defined-contribution pensions sit entirely outside the inheritance tax net, one of the most tax-efficient wealth transfer vehicles available in the UK.
Key Takeaways
- From 6 April 2027, most unused pension funds count towards the taxable estate and face inheritance tax at 40% above the nil-rate band threshold of £325,000
- The spousal and civil partner exemption is preserved, pension wealth passing to a surviving spouse or civil partner attracts no inheritance tax charge under the new rules
- Death-in-service lump sums paid from registered pension schemes are explicitly excluded from the April 2027 changes
What Are the Labour Inheritance Tax Pension Changes?
Rachel Reeves announced the reform at the Autumn Budget 2024. The Finance Act 2026 received Royal Assent on 18 March 2026, directly amending the Inheritance Tax Act 1984 to bring unused pension funds into the taxable estate for deaths on or after 6 April 2027.
Before that date, most defined-contribution pension funds sit entirely outside the estate. After it, they are aggregated with all other assets, property, savings, investments, and inheritance tax applies to the combined total above the nil-rate band.
HM Treasury estimates that approximately 10,500 estates will face an inheritance tax liability for the first time in the 2027–28 tax year as a direct result of this change.
For families where pension savings are substantial and estates are otherwise modest, the impact will be significant.
Why Pension Funds Escaped Inheritance Tax And Why That Is Now Changing?
Pension funds historically sat outside the inheritance tax net because they were never legally the property of the pension holder at death. Scheme trustees held pension assets under a discretionary trust, which meant the funds could not be brought into the taxable estate under the pre-2026 rules of the Inheritance Tax Act 1984.
The 2015 pension freedoms allowed defined-contribution holders to pass undrawn funds to any nominated beneficiary free of inheritance tax, accelerating the use of pension pots as intergenerational wealth transfer vehicles.
HM Treasury identified this as an unintended consequence. The Finance Act 2026 addressed it directly, amending the IHTA 1984 to override the discretionary trust principle for the purposes of inheritance tax liability.
The common mistake: Updating a pension nomination form does not reduce the inheritance tax liability under the new rules.
From 6 April 2027, the discretionary trust structure no longer shields pension funds from inheritance tax, the rules apply regardless of who is named as beneficiary, except a surviving spouse, civil partner, or registered charity.
Which Pensions Are Affected And Which Are Not?
Most defined-contribution pensions fall within the scope of the April 2027 changes. Several categories are explicitly excluded.
In scope: Pension types subject to the new inheritance tax rules:
- Self-Invested Personal Pensions (SIPPs) with undrawn funds
- Workplace money-purchase schemes with uncrystallised balances
- Residual funds remaining in drawdown pensions
- Most pension death benefit lump sums are payable on the pension holder’s death
- Personal pensions where the deceased had not yet commenced drawdown
Out of scope: Pension types explicitly excluded from the 2027 changes:
- Death-in-service lump sums paid from registered pension schemes
- Dependants’ scheme pensions continue after the pension holder’s death
- Nominees’ annuities and successors’ annuities
- Pension assets passing to a surviving spouse or civil partner
- Pension assets passing to a registered charity
- Certain pension credits awarded under a divorce settlement
Knowing whether a pension falls in or out of scope is the starting point, but the tax calculation, particularly where a beneficiary also faces income tax on drawdown, is where most families underestimate true exposure. See UK pension inheritance tax changes for further analysis.
How IHT on Inherited Pensions Is Calculated From April 2027?
Under current rules, a pension pot of any size passes outside the taxable estate entirely. From April 2027, it is aggregated with all other assets, and if the combined total exceeds the nil-rate band (£325,000), inheritance tax at 40% applies to the excess.
According to HMRC, the nil-rate band remains frozen at £325,000 until at least 2030. The residence nil-rate band of £175,000 applies only where a main residence passes to direct descendants, where it does not, the full pension pot is exposed above the standard threshold.
Labour’s inheritance tax policy includes simultaneous reforms to agricultural and business property relief, but the pension change affects the greatest number of estates from April 2027.
| Scenario | Before April 2027 | From April 2027 |
|---|---|---|
| Pension pot value at death | Outside estate, no IHT | Inside estate, aggregated with other assets |
| Estate £400,000 / Pension £200,000 | IHT on £75,000 excess above £325,000 NRB = £30,000 | IHT on £275,000 excess above £325,000 NRB = £110,000 |
| Death at age 75+, non-spouse beneficiary | No IHT; income tax on drawdown at marginal rate | IHT at 40% first; income tax on remainder, effective rate up to 67% |
| Assets passing to spouse or civil partner | No IHT | No IHT, spousal exemption fully retained |
Deloitte Associate Tax Director Rachel McEleney confirmed in October 2024 that where inheritance tax at 40% applies and a beneficiary pays income tax at 45% on the remaining drawdown fund, the effective combined rate reaches 67%, unchanged since the Finance Act 2026 passed.
Where a pension holder dies at age 75 or older, and the beneficiary is not a spouse, civil partner, or charity, double taxation applies.
Inheritance tax at 40% reduces the pot first. Income tax at up to 45% then applies to the remainder, producing an effective combined rate of up to 67%. No other UK asset class faces this double layer of taxation.
How the Tax Is Reported and Paid?
Personal representatives of the estate, not pension scheme administrators, and not pension beneficiaries directly, are primarily responsible for reporting and paying inheritance tax on inherited pension funds under the 2027 rules.
HMRC requires inheritance tax to be settled within six months of death to avoid interest charges, currently the Bank of England base rate plus 4%. The following sequence applies:
- The personal representative calculates the combined estate value, including the pension pot, and determines the total inheritance tax liability
- Inheritance tax is reported to HMRC and must be paid within six months of the end of the month in which the death occurred
- Where a beneficiary’s share of the pension inheritance tax liability exceeds £4,000, they may request that the pension scheme administrator pay their proportionate share directly to HMRC before releasing funds
- Where estate beneficiaries and pension beneficiaries are different people, the personal representative can recover the pension-attributable portion of the inheritance tax bill proportionally from the pension beneficiaries
This creates a liquidity problem where a will distributes assets differently from the pension nomination.
Pension Schemes Newsletter 164 (October 2024) confirmed HMRC’s intent to publish operational guidance for pension scheme administrators before April 2027, though that guidance remained in draft as of Royal Assent.
Five Planning Steps to Take Before 6 April 2027
Acting before 6 April 2027 is the only window to restructure arrangements under the existing rules. After that date, the new framework applies to all deaths regardless of when plans were made.
- Review pension nomination forms: Nominations are now relevant to who receives funds, not to whether those funds face inheritance tax. Update nominations to reflect the new landscape, prioritising spousal or civil partner nominations where inheritance tax deferral remains the goal
- Model the double taxation pension death risk specifically: Where a pension holder is over 75 and beneficiaries are non-spousal, the effective rate may reach 67%. A financial adviser can calculate the exact liability using current estate and pension values
- Consider drawing down pension funds during lifetime: Redirecting pension savings into ISAs, gifting within annual allowances, or other assets with cleaner inheritance tax treatment removes them from the estate calculation entirely. For strategies on reducing overall exposure, see how to avoid inheritance tax
- Review whole-of-life insurance: A whole-of-life policy written in trust can be structured to meet the projected inheritance tax liability without adding to the estate, providing beneficiaries with a liquid sum to settle the HMRC charge within the six-month deadline
- Update wills and consider direct gifting strategies: The pension entering the estate may have changed the overall taxable value materially
The House of Lords Economic Affairs Committee challenged the implementation framework in January 2026, citing concerns over the dual-payment mechanism’s complexity. HMRC guidance is expected before April 2027, planning should not wait for it.
Conclusion
The Labour inheritance tax pension changes mark the most significant shift in pension estate planning since the 2015 pension freedoms.
Unused pension funds enter the taxable estate for the first time from 6 April 2027, and where beneficiaries are non-spousal, the combined tax exposure can reach 67%.
FAQ
When do the Labour inheritance tax pension changes take effect?
The changes apply to deaths on or after 6 April 2027, legislated through the Finance Act 2026 (Royal Assent 18 March 2026). Deaths before that date remain under existing rules, most unused pension funds stay outside the taxable estate.
Does the spousal exemption still apply to pensions after April 2027?
Yes, pension assets passing to a surviving spouse or civil partner attract no inheritance tax under the new rules. Assets passed to any other beneficiary, including adult children, are fully subject to the April 2027 charge. For gifting alternatives, see the inheritance tax gift exemption rules.
What is the effective tax rate on a pension inherited after April 2027?
Where the estate exceeds the nil-rate band, and the beneficiary is not a spouse, inheritance tax at 40% applies first. If the beneficiary then draws the remainder at the 45% additional rate, the effective combined rate reaches 67%, confirmed by Deloitte Associate Tax Director Rachel McEleney in October 2024.
Are death-in-service benefits included in the inheritance tax changes?
No, death-in-service lump sums from registered pension schemes are explicitly excluded from the April 2027 changes. The new rules target unused defined-contribution pension funds and pension death benefits. Employees covered by group life insurance through a registered scheme are unaffected.
What happens to a SIPP when the owner dies after 6 April 2027?
A SIPP with undrawn funds forms part of the deceased’s taxable estate from April 2027. Inheritance tax at 40% applies to any amount above the nil-rate band. The SIPP inheritance tax changes end the discretionary trust shield, the undrawn pot size and the beneficiary’s identity both determine the final liability.
