From 6 April 2027 unused defined-contribution pension funds and most unused defined-benefit lump-sum death benefits enter the deceased's estate for inheritance tax. The reform was announced at Autumn Budget 2024 and the effective date sits on the upcoming Finance Act 2026. Our Wave 2 walkthrough at Pension IHT from April 2027 sets out the rule mechanics, the spouse-exemption position, the post-75 income-tax overlay, and the RNRB taper interaction.
This page answers a different question. With both the pension fund and the BTL portfolio inside the IHT base from age 67 onwards, which asset class does the retiring-age landlord draw on first? The pre-2027 textbook answer ("use pension last") is structurally undermined and the new sequence is not obvious without working through the numbers. Below: why 65 to 80 is the planning window, the two pure decumulation routes (sell property first vs draw pension first), a worked total-cost comparison on the Reid persona (£2.9m joint estate), the hybrid route that usually wins in practice, the pension-liability reporting mechanics on death so families know what happens administratively, and the cross-route comparison against direct property gifting (Wave 4 C4) and FIC value-freezing (Wave 4 C7).
Why 65 to 80 is the planning window
Most decumulation sequencing decisions for landlord couples play out in the 65 to 80 age band. The defaults set at 65 (when the pension fund first becomes accessible and the landlord typically starts thinking about reducing rental management workload) drive the trajectory through to second death. The £2,000,000 RNRB taper threshold under s.8D(5) IHTA 1984 is the strategic floor: a couple's combined estate landing below the threshold at second death keeps RNRB available in full (£175,000 plus £175,000 transferable = £350,000 against the residence); landing above the threshold withdraws RNRB at £1 for every £2 over and triggers a six-figure additional IHT exposure on a typical landlord estate.
A 65-year-old portfolio landlord with a £900,000 SIPP, a £1,600,000 BTL portfolio, and a £400,000 family home is at a joint estate of £2,900,000 today, well above the £2,000,000 threshold. Passive holding sees the estate grow at roughly 3% real over the 15-year decumulation window, landing at second death (typical age 85) at £3,500,000 to £4,000,000. The second-death IHT bill on the passive position, against £650,000 combined NRB and zero RNRB (tapered out), is in the order of £1,000,000 to £1,200,000. The same starting position with active decumulation can land below the threshold with full RNRB preserved and the second-death IHT bill at £200,000 or less. The decision made at 65 (which asset class to draw on, in what sequence, over what timescale) is the binding constraint on the eventual outcome.
Route one: sell property first
The sell-property-first sequence runs measured BTL disposals across the first decade of retirement and leaves the pension to draw down at basic-rate income tax in the second decade. The pattern looks like this for a five-flat £1,600,000 portfolio held since the early 2000s with a £600,000 aggregate latent gain:
- Ages 65 to 68: sell two of the five BTL flats (the highest-yield and most-management-intensive). Realised proceeds approximately £640,000, latent gain on these two approximately £240,000. CGT bill at 24% residential rate on the gain (the landlord is still in higher rates given the remaining rental income) approximately £56,000. Net proceeds £584,000 added to cash reserves.
- Ages 69 to 72: sell a third flat. Proceeds £350,000, gain £130,000, CGT £30,000. Two flats remain.
- Ages 73 to 75: sell a fourth flat. Proceeds £400,000, gain £160,000, CGT £38,000. One flat remains (often kept for the surviving spouse's ongoing income or for legacy purposes).
- Ages 76 to 85: pension drawdown begins. Annual drawdown £40,000 each (within the basic-rate band of £12,570 personal allowance plus £37,700 basic band for each spouse). Income tax £5,486 each per year (basic rate of 20% on the £27,430 above personal allowance). Cumulative income tax over 10 years: approximately £55,000 each, total £110,000 across the couple. Pension fund drawn to near-zero by age 85.
Aggregate decumulation tax cost across the 20-year window: CGT £124,000 plus income tax £110,000 = £234,000. Second-death position (age 85): residual one BTL flat £550,000 (assumed 3% growth on the held-to-death property), family home £550,000, cash £400,000 (mid-window spent down from the realised proceeds), residual pension £100,000. Total estate £1,600,000. Below the £2,000,000 threshold. RNRB available £350,000 in full. NRB available £650,000. Taxable estate £600,000. IHT at 40% = £240,000. Total tax across decumulation plus death: £474,000.
Route two: draw pension first
The pension-first sequence preserves the BTL portfolio intact through retirement and runs the pension as the primary income source. Same Reid couple, same starting position:
- Ages 65 to 77: pension drawdown £45,000 each per year (basic-rate band plus a small slice of higher-rate). Cumulative income tax over 12 years approximately £130,000 across the couple. Pension fund of £900,000 drawn to near-zero by age 77. Combined with continuing rental income from the unchanged £1,600,000 BTL portfolio, the couple's living standard is comfortable throughout.
- Ages 78 to 85: rental income alone funds remaining retirement. No further pension to draw. No active property sales. Modest annual gifting within the £3,000 annual exemption (£6,000 across the couple per year, cumulating to roughly £42,000 over the seven years, gifted to adult children outside the IHT base).
Aggregate decumulation tax cost across the 20-year window: income tax £130,000. CGT zero (no property sales). Second-death position (age 85): five BTL flats now worth approximately £2,500,000 (3% growth on the £1.6m original portfolio), family home £550,000, cash £100,000, residual pension zero. Total estate £3,150,000. Well above the £2,000,000 threshold. RNRB tapered out entirely (£1,150,000 over the threshold withdraws £575,000 of combined RNRB, which exceeds the £350,000 available, so RNRB is zero). NRB available £650,000. Taxable estate £2,500,000. IHT at 40% = £1,000,000. CGT zero for the beneficiaries on inheritance (death uplift under s.62 TCGA 1992 wipes the latent gain). Total tax across decumulation plus death: £1,130,000.
The comparison: £656,000 cheaper to sell property first
On the Reid figures: sell-property-first total tax £474,000; draw-pension-first total tax £1,130,000; the sell-property route is £656,000 cheaper. The headline driver is the £2,500,000 of BTL property remaining in the estate on the draw-pension route, which faces 40% IHT on its full death-date value, against the £550,000 single residual flat on the sell-property route. The CGT cost of selling (£124,000 in life at 24% effective rate) is much smaller than the IHT cost of holding to death (£1,000,000 at 40% on the un-realised position), and that 16-percentage-point gap, applied to £1.6m of property value, is the structural reason the sell route wins on this estate size.
The arithmetic is sensitive to inputs. Three sensitivities matter most:
- Property growth rate. Higher growth makes the held-portfolio route relatively more expensive on the IHT side. Lower growth (or a downturn) reduces the IHT exposure on the held portfolio and narrows the spread.
- CGT base cost. A higher base cost (smaller latent gain) reduces the CGT cost on the sell route. A lower base cost (larger latent gain) makes the sell route relatively more expensive. On a portfolio acquired recently with little latent gain, the sell route is very cheap; on a portfolio held since the 1990s with high latent gains, the CGT cost on the sell route can rise to 30% to 35% of realised proceeds and the spread narrows.
- Family structure and legacy preference. Some landlord families have a strong preference for inheriting the actual properties rather than cash, on family-business or sentimental grounds. The sell-property route delivers cash to the next generation (clean, divisible, easily invested or spent); the draw-pension route delivers the property portfolio intact (operationally heavier, but the property itself passes to the family). The £656,000 difference on the Reid figures is the price of that preference at this estate size.

The hybrid: usually the right answer in practice
A pure sell-property-first route concentrates CGT in the early retirement years, potentially pushing the landlord into the higher-rate band on rental income, which raises the effective CGT rate on the next disposal. A pure draw-pension-first route exposes the full BTL portfolio to the worst-case IHT outcome. The hybrid that usually wins in practice:
- Annual pension drawdown to fill the basic-rate band. Each spouse draws roughly £37,700 of taxable pension income per year above their personal allowance, paying 20% on the gross. Across the couple this consumes approximately £900,000 of pension over 12 years at low marginal income tax cost.
- One BTL disposal every 2 to 3 years across the early-to-mid retirement window. Realises CGT in measured chunks, uses the £3,000 annual CGT exemption each year, keeps the landlord below the higher-rate threshold for the year of disposal, and steadily reduces the property estate exposure.
- Annual gifts of £6,000 (combined £3,000 each spouse annual exemption) plus larger gifts under the normal-expenditure-out-of-income exemption (s.21 IHTA 1984) where the rental income comfortably exceeds normal living costs. Each gift starts its own 7-year clock and reduces the eventual second-death estate.
- One or two larger BTL gifts to adult children as PETs in mid-retirement (ages 65 to 68 ideally), hedged with 7-year decreasing-term life cover in trust. The mid-life corridor for these gifts is covered on our companion page at The 7-Year Clock for Mid-Life Landlords.
The hybrid is more advisory-intensive (each year's tax position is its own optimisation) and benefits from a five-year rolling plan that is revised annually against the actual realised positions. The output is usually a total-tax cost 10% to 25% lower than either pure route.
The FIC alternative: structural value-freeze instead of decumulation
For landlords with portfolios of £1.5 million plus and a strong preference for keeping the family in the property business rather than realising it to cash, the Family Investment Company route is the structural alternative. The donor transfers the BTL portfolio into a FIC at incorporation (incorporation relief under s.162 TCGA 1992 is rarely available for pure BTL but worth checking against the Ramsay business-substance test), retains preference shares with a frozen-coupon dividend providing retirement income, and gifts growth shares to the next generation as PETs starting the 7-year clock.
The FIC route does not solve the pension-IHT-from-April-2027 question in itself (the pension is separate from the FIC structure). It does change the property-side decumulation question: with the portfolio inside a FIC, the founder is taking dividend income on preference shares (frozen value, no growth, fully in the founder's estate as the share value) rather than realising property to cash. The growth in property value over retirement accrues to the growth shareholders (the next generation) outside the founder's estate from the gift date plus 7 years. The pension-side decision can then run on its own merits: drawdown to basic rate, charity nominations on the residual, spouse-exemption deferral to second death. The FIC route's IHT framing is on our forthcoming page (Wave 4 C7).
The pension-liability reporting mechanics on death
From 6 April 2027 the Personal Representatives of the deceased's estate carry primary liability for reporting and paying the IHT on the unused pension fund, per the published consultation outcome. The mechanic integrates into the existing IHT400 estate-return process:
- Within 12 months of the end of the month of death, the PRs file the IHT400 with a dedicated schedule for the pension component (the form numbering is being finalised by HMRC in the implementation guidance; the principle is that the pension is on the IHT400 return, not on a separate trust or pension form).
- The pension scheme administrator provides a death-value statement to the PRs giving the unused fund value at the date of death. The statement is the source document for the IHT400 schedule; PRs need scheme administrator contact details on file with the deceased's records.
- The IHT on the pension component is part of the overall estate IHT liability. The PRs pay it from estate funds in the normal way, or they can request payment from the pension scheme administrator under the Direct Payment Scheme that exists for current pre-2027 in-scope pensions (some discretionary scheme death benefits already fall in IHT). The Direct Payment Scheme avoids the PRs having to advance the IHT from their own funds.
- The PRs are the primary debtor for the IHT. The scheme administrator is not. Industry lobbied for the scheme administrator to be primary debtor in the original consultation; the published outcome confirmed PR primacy. Practical implication: PRs need to plan for the pension-IHT liability as part of the overall estate IHT cash-flow position, and the executors' insurance market is adapting to provide cover for the extended PR liability.
The post-2027 estate administration is operationally heavier than the pre-2027 process. Families running a landlord estate should ensure that the deceased's will appoints PRs who are willing to take on the extended responsibility (typically professional executors charge more for post-2027 estates with pension components) and that the pension scheme administrator details are kept on file alongside the BTL portfolio documents and the family home title.
