The IHT change with the largest absolute impact on landlord estates in the current reform cycle is not the BPR/APR cap arriving on 6 April 2026 (which, per the Pawson trading bar, leaves most BTL portfolios unaffected). It is the 6 April 2027 reform bringing unused defined-contribution pension funds and lump-sum death benefits into the deceased's estate for inheritance tax. Pension wealth that has historically passed to the next generation outside IHT, often the largest single asset in a landlord's retirement balance sheet, becomes IHT-exposed from a single overnight commencement date. For landlords who built their retirement plan around drawing rental income first and leaving the pension untouched as a tax-efficient legacy, the underlying maths is inverted: the previously IHT-free asset becomes the most IHT-exposed one.

This page covers the reform mechanism, the before-and-after worked impact on a typical landlord estate, the post-75 double-tax interaction with the existing income-tax-on-drawdown treatment, the spousal and charity exemptions that survive the change, and the pre-April-2027 action items. The page is the depth on the pension question; the wider IHT context is at the inheritance tax on rental property portfolios pillar, the cross-cutting reform overview is at our 2026 landlord tax changes guide, and the strategic-decision framework that sequences pension-IHT planning against the other reforms is at our IHT decision framework. The £2,000,000 RNRB taper that the pension reform interacts with mechanically is covered in depth at the RNRB taper page.

The reform in one paragraph

From 6 April 2027, most unused defined-contribution pension funds and unused lump-sum death benefits from registered pension schemes form part of the deceased's estate for IHT. The change was announced at Autumn Budget 2024 and confirmed in the consultation outcome published in 2025. Death-in-service benefits payable from a registered pension scheme are excluded entirely from the estate value. Dependants' scheme pensions paid as recurring income are not in scope. Personal representatives, not scheme administrators, will be liable to report and pay the IHT on the pension component of the estate. Pre-6-April-2027 deaths are unaffected. The reform changes WHAT is in the estate for IHT; the existing income-tax treatment of drawdown by beneficiaries (tax-free pre-75 / marginal-rate post-75) is unchanged.

The pre-2027 baseline: why landlords chose to "use pension last"

Before 6 April 2027, the IHT-free status of DC pensions on death drove a specific decumulation sequence for landlords approaching retirement. Rental income from the BTL portfolio was the obvious first tap because the portfolio could not pass to the next generation without 40% IHT exposure on whatever sat in the estate. ISAs were the second tap (income tax-free but IHT-exposed at 40% in the estate). The DC pension was the third tap, intentionally left untouched where liquidity allowed, because it was outside the IHT computation and would pass to nominated beneficiaries gross. A landlord at 65 with £1,200,000 of net BTL equity, £200,000 of ISAs and £600,000 in a SIPP, drawing £40,000 a year of net retirement income, typically drew first from rents, second from ISAs, and never (or rarely) touched the SIPP. The plan was for the SIPP to pass to the children at age 80 or 85 without IHT.

The plan worked because of the asymmetry between the IHT treatment in life (the SIPP was outside the estate) and the income tax treatment on death (the beneficiaries paid no income tax on a pre-75 death, or marginal-rate income tax on a post-75 death as they drew down). Pre-75 death produced essentially zero combined tax on the SIPP passing to the next generation. Post-75 death produced only the beneficiary's marginal-rate income tax, no IHT.

The 2027 mechanism: what enters the estate

From 6 April 2027, the assets that enter the IHT estate on the member's death are:

  • Unused DC pension funds. Both uncrystallised funds and crystallised funds in flexi-access drawdown that have not been drawn down to zero. The valuation is the open-market value of the fund (for unit-linked SIPPs, the unit value; for asset-backed SIPPs, the underlying asset values).
  • Unused DB lump-sum death benefits. A defined-benefit scheme that pays a lump sum on death rather than (or in addition to) a dependant's pension brings the lump-sum entitlement into the estate.
  • Annuity protected funds. Where the deceased had a lifetime annuity with a guaranteed period or value-protected element that pays out on death, the value paid out is in the estate.

Excluded from the estate:

  • Death-in-service benefits from a registered pension scheme. Confirmed by the published consultation outcome and structural to the reform: these benefits, often a multiple of salary, were the historic motivation for the pension-IHT exemption and were retained outside the IHT base.
  • Dependants' scheme pensions paid as recurring income. A surviving spouse drawing a DB scheme pension after the member's death pays income tax on the pension income but no IHT on the underlying entitlement.
  • Pensions of those who die before 6 April 2027. The commencement date is the date of death, not the date of probate or any other downstream event.

Personal representatives report the pension component on a schedule to IHT400, alongside the rest of the estate. The pension scheme administrator provides the date-of-death value to the PRs within the standard scheme-administrator timeframe. IHT on the pension is paid in cash by the estate (with the PRs typically requesting a partial pension drawdown to fund the IHT, treated as a beneficiary withdrawal under the existing income-tax rules).

The £2 million RNRB taper interaction

The reform is materially worse for landlord estates than for non-landlord estates because most landlord estates sit close to or above the £2,000,000 RNRB taper threshold before the pension is added. The taper at section 8D(5) IHTA 1984 measures E (the estate value immediately before death) on the broad section 5 basis, with no carve-out for pensions. From 6 April 2027, the pension fund counts in E.

Worked impact for a representative landlord at 65 with £1,800,000 of property and other assets plus a £700,000 SIPP:

  • Pre-April-2027 death. E = £1,800,000. Below the £2,000,000 taper threshold. Full default RNRB of £175,000 plus full transferable RNRB of £175,000 (spouse pre-deceased, used 0%). Total IHT allowances: £1,000,000 (NRBs and RNRBs). Pension passes outside IHT to beneficiaries at zero IHT cost. Chargeable estate: £800,000. IHT: £320,000 at 40%.
  • Post-April-2027 death. E = £2,500,000. Taper withdrawal: £250,000. Default and transferable RNRB reduced to £100,000 in total. Pension now in the estate. Total IHT allowances: £750,000 (NRBs £650,000 plus surviving RNRB £100,000). Chargeable estate: £1,750,000. IHT: £700,000 at 40%.

The reform produces a £380,000 increase in the IHT bill on the same nominal wealth, the same person, the same beneficiaries, the same will. £280,000 of that increase is IHT on the pension itself (40% of the £700,000 fund). £100,000 is collateral damage from the £250,000 of RNRB withdrawn by the taper now that the pension counts in E. The RNRB interaction is the under-reported feature: landlords focused on "the pension is 40% IHT" miss the additional taper-driven cost on the rest of the estate.

The post-75 double-tax interaction

The income-tax treatment of pension death benefits is structurally unchanged: tax-free to the beneficiary on a pre-75 death; taxed at the beneficiary's marginal rate as pension income on a post-75 death. The April 2027 reform adds IHT on top. For a post-75 death the same pension fund can therefore attract IHT in the estate AND income tax on the beneficiary's drawdown.

Worked impact for a £500,000 SIPP passing on a post-75 death to a higher-rate-taxpayer beneficiary:

  • IHT in the estate at 40% (assuming above-allowance estate): £200,000. The estate writes a cheque for £200,000 funded by partial drawdown from the SIPP.
  • Net fund passing to beneficiary: £300,000.
  • Beneficiary draws down over time at higher-rate income tax (40%): cumulative income tax £120,000 on the £300,000 gross fund.
  • Net retained by beneficiary: £180,000.

The effective rate of tax on the pension passing to the beneficiary is 64% (£320,000 of combined tax on a £500,000 starting fund). For an additional-rate beneficiary (45% income tax) the effective rate climbs to 67%. Pre-April-2027, the same fund passing on the same post-75 death produced only the income-tax leg, an effective rate of 40% (higher-rate) or 45% (additional-rate). The post-75 double-tax interaction is what makes the reform materially punitive for retired landlords who had assumed pre-75 mortality risk and were planning the pension legacy in their late 70s and 80s.

Pre-75 deaths after April 2027 escape the income-tax leg (the £500,000 fund passes net of IHT but free of income tax to the beneficiary), so the effective rate is 40%. Same as a pre-2027 estate at the equivalent IHT-bracket. The pre-75 death scenario is therefore much less punished by the reform than the post-75 one; for landlords in their late 60s and early 70s, the question of whether to accelerate drawdown is partly a mortality-risk-acceptance question.

Spousal exemption and charity exemption still apply

Section 18 IHTA 1984 (spouse and civil partner exemption) operates on pension funds inherited by the surviving spouse exactly as it does on other estate assets. A landlord leaving the unused DC pension to the surviving spouse pays no IHT on the first death. The pension transfers to the spouse and is then in the spouse's own pension wrapper (a "successor's flexi-access drawdown" arrangement) or paid out as a lump sum. The IHT trigger defers to the second death. The reform changes what's in the estate, not the spousal exemption that operates on it.

Charity exemption under section 23 IHTA 1984 also continues to apply. Pension benefits nominated to a registered charity pass IHT-free. The 36% reduced IHT rate (where the chargeable estate includes a charitable legacy of at least 10% of the baseline amount) is available across the whole estate including the pension component. For estates in the £2,500,000-plus tier, the charity-funded 36% rate route can be the single largest IHT saving available: a £250,000 nomination from a £600,000 pension to a registered charity drops the rate on the chargeable estate from 40% to 36%, often saving substantially more in IHT than the charitable gift itself costs the estate's residual beneficiaries.

The spousal and charity exemptions are unchanged because they were designed to be neutral to the asset class within the estate; they apply to the IHT calculation on whatever is in the estate. The reform brings new assets into the estate but does not alter the exemption rules that operate on them.

The "use pension last" strategy is inverted: what replaces it?

The optimal decumulation sequence for many retired landlords flips from April 2027:

  • Pre-2027 sequence. Rental income first (IHT-exposed in estate, taxed at marginal income tax in life). ISA drawdown second (income-tax-free in life, IHT-exposed in estate). Pension last (IHT-free in estate via the historic exemption; income-taxed only on the beneficiary's eventual drawdown after death).
  • Post-2027 sequence. Pension drawdown first within the basic-rate band (income tax at 20%, removes the fund from future IHT exposure). ISA drawdown second (income-tax-free; remains IHT-exposed in the estate but no acceleration penalty). Property equity third (24% CGT on a sale, or 25% IHT on lifetime CLTs to trusts, or 0% on PETs surviving the 7-year clock). The previously IHT-free pension is now the asset to drain first.

The basic-rate-band test is important. Drawing down the pension above the basic-rate band (£37,700 of pension income on top of the personal allowance, for 2026/27) tips into higher-rate income tax at 40%, which is the same rate as the future IHT exposure. The arithmetic at higher-rate is neutral pre-75 (40% income tax now vs 40% IHT later) and slightly negative post-75 (40% income tax now vs 40% IHT + 40% income tax later, but with cash flow advantages to drawing later). At basic-rate the maths is clearly positive (20% now vs 40% later, regardless of pre-75 or post-75). For landlords using pension contributions as a section 24 mitigation route (paying gross earnings into the pension to drop into the basic-rate band and recover the otherwise-restricted finance-cost relief), the contribution side of the strategy is intact but the IHT-side legacy benefit drops away from April 2027; the full income-tax-and-IHT picture is in our Section 24 pension contributions page.

Practical implication: landlords whose pension fund is large enough that drawing it down at basic-rate band over a long retirement leaves significant residual fund at death should consider front-loading the drawdown, even if the spend is not needed. Drawn-down cash that ends up in an ISA wrapper (subject to annual subscription limits of £20,000) is income-tax-protected from then on, though still IHT-exposed. Drawn-down cash that ends up in a Junior ISA for grandchildren (£9,000 per year, locked until 18) is income-tax-protected and IHT-protected after 7 years as a PET. Drawn-down cash that funds bond ladders or premium bonds is income-tax-managed but remains IHT-exposed.

The decision framework at our IHT framework page sequences the pension drawdown decision against the other IHT reforms (BPR/APR cap, RNRB taper). For mixed estates where multiple changes interact, the sequencing matters.

Beneficiary nominations: still useful, for different reasons

Pre-April-2027, beneficiary nominations drove BOTH who got the pension AND whether IHT applied. Where the scheme had discretion withdrawn (most legacy schemes), the nomination was binding and the trustee paid out per nomination, outside the estate. Where the scheme had discretion (most modern SIPPs), the trustees considered the nomination and routinely followed it. IHT-free in either case.

Post-April-2027, beneficiary nominations drive WHO gets the pension but no longer drive WHETHER IHT applies. The IHT is at 40% on the fund value at death regardless of who the beneficiary is (subject to the spousal and charity exemptions where the nominated beneficiary is the surviving spouse or a registered charity). What the nomination still controls:

  • Pre-75 vs post-75 income-tax treatment of the residual. The nominated beneficiary determines whose hands the fund is in for the income-tax-on-drawdown calculation. Nominating an adult child (basic-rate taxpayer) rather than the surviving spouse (additional-rate taxpayer through accumulated investment income) reduces the post-75 income-tax leg.
  • Successor flexi-access drawdown options. The nominated beneficiary can keep the fund in a pension wrapper as their own successor's flexi-access drawdown, deferring drawdown over their own lifetime. This is unchanged by the reform and remains valuable.
  • Spousal exemption. Nominating the surviving spouse (or civil partner) protects against the first-death IHT entirely, deferring the IHT crystallisation to the second death.
  • Charity nominations. The 36% rate route requires a charitable legacy of at least 10% of the baseline; a meaningful charity nomination of the pension can land the estate-wide 36% rate.

Review nominations on every pension arrangement before April 2027. The nomination form is administrative but the post-2027 implications are material.

Five action items before 6 April 2027

  1. Calculate today's IHT exposure including the pension as if 2027 rules already applied. The size of the change is the trigger for everything else. A landlord at £1,500,000 of total wealth including a £400,000 pension has a different planning conversation from one at £3,000,000 including a £900,000 pension.
  2. Review beneficiary nominations on all pension arrangements. Spouse nomination preserves the spousal exemption; adult-child nomination may reduce the post-75 income-tax leg; charity nomination can land the 36% rate. Forms should be re-signed where stale or post-divorce.
  3. Re-model decumulation. If currently leaving the pension untouched, model basic-rate-band drawdown between now and April 2027 (and beyond). Drawn cash can be ISA-protected (£20,000/year), JISA-protected, gifted with the 7-year clock running, spent, or invested in BPR-qualifying instruments (where the trading bar is met and the £1,000,000 cap leaves room).
  4. Confirm death-in-service cover sits within a registered scheme. Cover via the pension scheme is excluded from the estate; cover via a free-standing life policy is in the estate unless written in trust. Property-company employer-paid life policies may be either; check with the scheme administrator.
  5. Coordinate with the RNRB taper plan. Where the pension pushes E above the £2,000,000 wall from April 2027, the taper-driven cost on the rest of the estate can be larger than the headline IHT on the pension itself. Lifetime gifts surviving 7 years, FIC dilution, or spousal-equalisation can drop E back below the threshold. The RNRB taper page covers the mechanics; the planning conversation is sequenced from the IHT decision framework.

Closing pointers

The April 2027 pension-IHT reform is the largest IHT change in the current cycle for landlord estates, but it is also the most planning-responsive: the eleven months between now and commencement allow for the decumulation re-modelling, the nomination reviews, and the coordinated work with the RNRB taper plan that the reform demands. Estates above the £2,000,000 RNRB taper threshold (or that the pension addition will push above it) should treat the reform as the trigger for a comprehensive pre-2027 review. Estates well below the threshold can proceed more gradually but should still confirm beneficiary nominations and consider whether basic-rate-band drawdown materially reduces the post-2027 exposure.

The reform interacts with all three of the headline IHT changes (BPR/APR cap from April 2026, the residence-based regime from April 2025, the RNRB taper unchanged but newly aggravated by pension inclusion). Working through the combined picture, with the help of the decision framework, is the planning task for the next eleven months.
