For years, financial advisers quietly pointed clients toward pensions as one of the last legitimate shelters from inheritance tax. Outside the estate, largely untouched, passed on cleanly. That corner of estate planning is being demolished — and most people haven’t noticed yet.
The Autumn Budget 2024 set in motion changes that, from 6 April 2027, will drag certain unused pension funds into the taxable estate for the first time. The mechanics aren’t just complicated. They interact with rules most people have never heard of — including a property allowance trap that can cost a family more than the pension itself.
This guide covers what’s actually changing, who it hits hardest, and what you can still do before the window closes. For more guides on UK tax and estate planning, visit Pure Magazine.
Quick Answer (2026): Under current rules, most pension funds sit outside your estate and attract no inheritance tax. From 6 April 2027, unused pension funds and certain death benefits are expected to be included in your estate for IHT purposes. If your total estate — home plus pension — exceeds £2 million, you may also lose part of your property allowance. Planning before April 2027 is essential; the options available now will not exist after the deadline passes.
What Inheritance Tax on Pensions Actually Means
Inheritance tax is charged on your estate — the total value of everything you own when you die, above your nil-rate band threshold. The reason pensions escaped this for decades wasn’t an oversight. Most occupational and personal pensions are held in discretionary trusts, which means the pension provider — not you — legally controls the asset. Assets you don’t own can’t form part of your estate.
That trust structure still exists. But the 2027 reforms effectively overrule it for IHT purposes, requiring certain pension death benefits and unused funds to be reported and valued as part of the estate, regardless.
The distinction that matters is between discretionary schemes (SIPPs, personal pensions, most workplace pensions) and statutory schemes (certain public sector pensions). Some statutory schemes — notably older defined benefit public sector arrangements — were already within the estate for IHT. The 2027 change primarily targets discretionary schemes, which until now have largely escaped the net.
How the Rules Change: 2026 vs 2027
| Situation | Before April 2027 | From April 2027 (expected) |
|---|---|---|
| Death before age 75 | No IHT, no income tax for beneficiaries | Pension may be included in the estate for IHT |
| Death after age 75 | No IHT; beneficiaries pay income tax on withdrawals | IHT may apply at the estate level; beneficiaries still pay income tax on withdrawals |
| Transfer to spouse | IHT-free | IHT-free transfer remains; income tax applies on withdrawals after age 75 |
| Charity lump sum death benefit | IHT-exempt | Remains exempt |
| Death-in-service benefit | Outside estate | Typically remains outside the estate if still employed |
The combination of IHT at the estate level and income tax when beneficiaries draw funds — particularly after age 75 — is what pushes effective rates beyond 40%. When IHT reduces the estate, and then income tax applies to whatever’s left, the combined rate on pension funds can exceed 60% in some scenarios. That’s not a technicality. That’s a cash-flow problem for families expecting to inherit a meaningful sum.
The RNRB Taper: The Hidden Cost Most People Never See Coming
The Residence Nil Rate Band (RNRB) is an additional £175,000 allowance — on top of the standard £325,000 nil-rate band — available when you pass a home to a direct descendant. At its maximum, a couple can pass on up to £1 million entirely free of inheritance tax: two nil-rate bands (£650,000) plus two RNRBs (£350,000).
The catch is the taper. For every £2 your estate exceeds £2 million, the RNRB reduces by £1. At £2.35 million, the entire RNRB is gone.
Here’s where pensions create the trap. Under 2027 rules, a pension fund that was previously invisible to IHT calculations gets added to the estate valuation. An estate that sat safely under £2 million can cross the threshold simply because of pension savings — and suddenly, the RNRB that protected the family home starts shrinking.
Consider this scenario. Sarah lives in London. Her house is worth £1.8 million. She has a SIPP worth £400,000 that she hasn’t drawn down. Under current rules, the pension sits outside the estate; her taxable estate is £1.8 million, and her RNRB is untouched. Under 2027 rules, her total estate becomes £2.2 million — £200,000 over the threshold. Her RNRB reduces by £100,000. She doesn’t just pay tax on the pension. She loses property relief on the house. Her family’s bill increases by £40,000 before a single pension withdrawal is made.
It’s a trap, plain and simple — and it’s the detail most guides on this topic skip entirely.
Who Actually Runs This: The LPR vs PSA Distinction
Early commentary on the 2027 changes often described pension providers (Pension Scheme Administrators, or PSAs) as the parties responsible for reporting and paying any IHT due. That has since been clarified. Under the updated framework, Legal Personal Representatives — your executors — carry primary responsibility for reporting pension values to HMRC and coordinating payment of tax.
This matters enormously if you’re choosing an executor, or if you’ve been named as one. The PSA’s role is to cooperate with the LPR and provide valuations. The LPR’s role is to report those valuations, engage with HMRC, and ensure tax is paid. If your executor has no financial background and no awareness that pension values need to be reported, delays are almost guaranteed.
Brief your executor now. This isn’t optional under the new rules — it’s a legal responsibility they’ll carry from 2027 onwards.
The 50% Withholding Rule (And Why Beneficiaries Won’t Get Paid Quickly)
One of the most practical — and least discussed — aspects of the 2027 framework is the administrative mechanism for ensuring IHT gets paid before pension funds are distributed. Where inheritance tax is expected to be due, executors can instruct pension providers to withhold up to 50% of the pension death benefit while tax calculations are confirmed and payment arranged. This can continue for up to 15 months.
For a beneficiary expecting access to a lump sum pension, this isn’t an abstract inconvenience. It means the money they’re counting on — potentially for months — is held back while HMRC and the executor work through the numbers. If the estate has limited liquid assets (cash, easily sold investments), it may struggle to pay the IHT that’s due before the pension is released. The pension is effectively frozen to guarantee payment of the tax it now triggers.
The liquidity question is one that most estate plans don’t address head-on. If your estate’s cash comes mainly from the pension, and the pension is being withheld to pay IHT, the executor faces a circular problem. Planning for this before 2027 — whether through life insurance written in trust, or ensuring other liquid assets exist — is practical rather than optional.
Spousal Transfers: Still Protected, But Not Tax-Free Forever
Transfers between spouses and civil partners remain inheritance tax-free under the 2027 rules. If you die and your pension passes to your spouse, no IHT applies at that stage. The complication comes later.
If you die after age 75 and your pension passes to your spouse, any withdrawals they make from the inherited fund will be taxed as their income. This isn’t legally double taxation — IHT didn’t apply at the first death — but it can feel that way when a surviving spouse draws funds that came from a lifetime of saving and finds them taxed at their marginal income tax rate. Depending on their total income, that could mean 20%, 40%, or 45% income tax on every withdrawal.
For couples where both partners have substantial pension savings, the interaction between the first death, the second death, and the combined estate value deserves separate analysis — not just a standard “you’re protected as a couple” assumption.
Exceptions Worth Knowing
A few categories remain genuinely outside the new framework.
Charity lump sum death benefits stay exempt from IHT regardless of the 2027 changes. If a pension scheme pays a lump sum directly to a registered charity on death, no tax applies.
Death-in-service benefits — the lump sum paid if you die while employed — are typically held in a separate discretionary trust and are generally expected to remain outside the estate, provided the employment relationship still exists at death.
Very small pension pots — under a £1,000 de minimis threshold — may not be drawn into the IHT calculation under the 2027 rules. This affects relatively few people in practice, but it’s worth knowing if you have a dormant old workplace pension with a nominal balance.
Annuities as an IHT Strategy (2026 Planning Trend)
Something financial advisers are revisiting in 2026 — specifically in response to the 2027 changes — is the use of lifetime annuities as an inheritance tax reduction tool. The logic is straightforward. When you use a pension fund to buy a lifetime annuity, the capital leaves your estate permanently. You receive a guaranteed income for life, but the lump sum no longer exists to be taxed at death.
Before the 2027 changes, this trade-off rarely made sense from an IHT perspective — the pension was outside the estate anyway. Now, for someone with a large SIPP who doesn’t need the flexibility of drawdown, converting some or all of the fund to an annuity actively reduces their taxable estate.
The trade-off is real: you lose access to the capital, the income is fixed, and annuity rates aren’t what they once were. But for estates sitting just above the £2 million RNRB taper threshold, annuitising part of the pension fund could preserve the full property allowance and save considerably more than the lost flexibility is worth.
The Key Stakeholders Under the 2027 Framework
Understanding who does what avoids costly confusion during probate.
The Legal Personal Representative (LPR/Executor) is responsible for reporting the pension fund value to HMRC, coordinating with the pension provider, paying any IHT that falls due, and managing the 50% withholding process where applicable.
HMRC receives the report, confirms the valuation, issues any payment demands, and can review the figures if they appear incorrect.
The Pension Scheme Administrator (PSA/Provider) supplies the fund valuation, cooperates with the LPR’s instructions, and holds funds during the withholding period. The PSA does not initiate the IHT process — that responsibility now sits with the executor.
A well-briefed executor who understands these roles before the estate falls into administration makes the difference between probate taking 12 months and probate taking 18.
The Probate Delay Nobody Is Planning For
Probate — the legal process of administering an estate — already takes longer than most families expect. Adding pension valuations into the mix creates a new bottleneck. The executor must obtain a formal valuation from the pension provider, report it to HMRC, wait for HMRC to confirm or challenge the figure, and only then can the full probate application proceed.
If the estate spans multiple pension schemes — an old workplace pension here, a SIPP there — each requires a separate valuation. Each valuation request takes time. HMRC reviews can extend the process further. The practical consequence is that asset beneficiaries were counting on — including the house, as well as the pension — may be locked for considerably longer than they anticipated.
International Complexity: UK Pensions and Non-Residents
One area the 2027 guidance has not fully resolved is the treatment of UK pension funds held by non-residents — British expats, in particular. If a UK citizen living abroad holds a UK SIPP and dies domiciled outside the UK, the interaction between UK IHT rules and the pension fund’s inclusion in the estate remains unclear in some cases.
For expats with UK pension savings, taking specialist cross-border advice before April 2027 is advisable rather than assuming the UK rules will simply not apply.
Common Mistakes That Will Cost Estates Money
The biggest mistake is the assumption that “pensions are outside the estate” will continue to be true after April 2027. That was a reasonable default for most of the last 25 years. It no longer is.
The second is ignoring the RNRB interaction. People who’ve checked their estate value against the £2 million threshold and concluded they’re safe haven’t done the full calculation if they have a substantial pension. The pension now counts. The threshold hasn’t moved.
Third: failing to update beneficiary nomination forms. An outdated nomination doesn’t just create awkward family situations — it can mean pension funds are paid to someone whose circumstances have completely changed, or delayed while the pension provider tries to establish who should actually receive the benefit. The nominations you made at 35 may not reflect who you’d want to benefit at 65.
Fourth: assuming executors will know what to do. They won’t, unless you tell them. The new reporting and withholding responsibilities are not instinctive, and most lay executors have never encountered them. Leave clear instructions.
Finally: waiting. The most common planning strategy for the 2027 changes — doing nothing until it becomes urgent — is also the most expensive. Options that exist now close after April 2027.
Your 2027 Readiness Checklist
Before April 2027, work through the following.
- Calculate your total estate, including pension funds. Does the combined figure exceed £2 million? If so, check the RNRB taper impact specifically.
- Review your pension beneficiary nomination forms. Are they current? Do they reflect your actual wishes?
- Assess liquidity. If IHT becomes due, can your estate pay it without the pension being the only source of cash?
- Brief your executor. Explain the new reporting responsibilities and the 50% withholding mechanism. Consider whether a professional executor makes more sense for a complex estate.
- Consider whether drawdown, annuity, or gifting strategies make sense given your estate size and the RNRB threshold.
- If you’re an expat with UK pension savings, get cross-border advice before making any assumptions about how the rules apply to you.
Real Scenario: When the Pension Becomes the Problem
David is 68, retired, with a house in Surrey worth £1.75 million and a SIPP he’s barely touched — currently worth £450,000. Under pre-2027 rules, his taxable estate is £1.75 million. His RNRB is intact. His two adult children stand to inherit a substantial sum relatively efficiently.
Under the 2027 rules, his estate is £2.2 million. The RNRB reduces by £100,000 — wiping out £40,000 of tax-free allowance. The pension itself, after IHT at 40%, leaves a smaller net benefit. And if David dies after 75 and his children inherit the residual pension, they’ll pay income tax on every withdrawal on top.
The pension he preserved as a “safety net” is now the asset generating the largest tax bill. His estate planning, which looked sensible in 2024, needs updating before 2027 if he wants his children to benefit as he intended.
FAQs
Q. Do you pay inheritance tax on pension funds in 2026?
No—under 2026 rules, most pension funds are not subject to inheritance tax because they sit outside your estate.
Pension death benefits are usually distributed at the discretion of pension scheme administrators, keeping them outside inheritance tax (IHT). However, from April 2027, certain unused pension funds and death benefits may be included in the estate, making them potentially liable for IHT.
Q. Will including pensions in my estate affect my property tax allowance (RNRB)?
Yes—adding pension funds to your estate can reduce or eliminate your Residence Nil Rate Band (RNRB).
If your total estate exceeds £2 million, the RNRB tapers by £1 for every £2 above the threshold. Including pension funds in your estate from 2027 could push you over this limit, increasing the inheritance tax due on your home.
Q. What is the 50% withholding rule on pension death benefits?
Executors can request pension providers to withhold up to 50% of pension death benefits for up to 15 months while inheritance tax is settled.
This rule helps ensure IHT is paid, but can delay distributions to beneficiaries. It also creates liquidity challenges if the estate lacks cash to cover tax liabilities.
Q. Who reports pension values to HMRC for inheritance tax after 2027?
The Legal Personal Representative (executor) is responsible for reporting pension values to HMRC.
Pension scheme administrators provide the valuation, but the executor must include it in the estate, calculate inheritance tax, and ensure payment. This significantly increases administrative responsibility after 2027.
Q. Do pensions passed to a spouse attract inheritance tax?
No—pensions transferred to a spouse or civil partner are exempt from inheritance tax.
However, if the original pension holder dies after age 75, the surviving spouse will usually pay income tax on withdrawals from the inherited pension fund.
Q. Are death-in-service benefits subject to inheritance tax after 2027?
Generally, no—death-in-service benefits are expected to remain outside the inheritance tax net.
These benefits are typically held in a discretionary trust and paid separately from the estate, provided the individual was still employed at the time of death.
Q. Which pension types are affected by the 2027 inheritance tax changes?
The changes mainly affect discretionary pension schemes like SIPPs and defined contribution workplace pensions.
These schemes currently sit outside the estate but may be included for inheritance tax purposes from April 2027. Some public sector or statutory schemes are already treated differently and may not see major changes.
Q. Can converting a pension to an annuity reduce inheritance tax?
Yes—buying an annuity can reduce your taxable estate and potentially lower inheritance tax exposure.
When you convert pension funds into a lifetime annuity, the capital is removed from your estate. This strategy may help preserve the Residence Nil Rate Band, especially for estates near the £2 million threshold.
Q. Can HMRC’s valuation of my pension be challenged?
Yes—executors can challenge a pension valuation if they believe it is incorrect.
HMRC allows reviews where evidence supports a different valuation. Complex pensions, such as defined benefit schemes or those with guarantees, may require professional valuation support.
Q. How are UK pensions taxed for expats under inheritance tax rules?
The tax treatment of UK pensions for expats remains uncertain as of 2026 and depends on residency and domicile status.
Cross-border inheritance tax rules are complex, and the 2027 changes may apply differently depending on your circumstances. Specialist tax advice is essential before making estate planning decisions.
