A large UK pension pot used to make a simple inheritance story tempting: spend ISA and taxable assets first, leave the pension alone, and let heirs inherit the remaining pot. The planned 2027 pension-IHT reform weakens that shortcut, so this scenario compares three educational paths: spend and gift more, draw pension earlier, or preserve a larger care and spouse reserve.
The household is a retired UK homeowner couple, both around 68, with about £1.25m of investable assets across a defined-contribution pension, ISAs, taxable investments, and cash. Their pension pot could be anywhere in the brief's £500k-£1.5m range, but the calculator pools wrappers because it cannot directly model pension, ISA, Income Tax, Capital Gains Tax, inheritance tax, or care-fee rules.
This is not an IHT calculator. It is a resilience test for a high-asset household asking whether inheritance goals should change retirement spending, gifting, drawdown order, and care reserves before the planned 6 April 2027 pension-IHT change. Exact tax exposure, scheme process, beneficiary treatment, and future HMRC guidance all need verification before anyone acts.
The base variants use the same starting balance and secure income, then change gifts, tax-friction proxy, lifestyle spending, and the late-life care reserve.

Keep spouse and care resilience high before prioritising heirs
Pooled investable assets:£1.25m in the model. In reality this might be a £500k-£1.5m DC pension plus different ISA, GIA, and cash balances.
Secure income: two full new State Pensions are modeled at about £2,091/month combined, and DB/annuity income adds £2,500/month.
Spending anchor: the branches use £4,600-£5,400/month of core spending, then layer gifts, tax/admin friction, home adaptations, and care reserve shocks on top.
Care reserve: every path reserves at least £175k later in life, because care and survivor security can dominate a tax-led estate plan.
All three paths are designed to remain solvent in the base case. The point is not whether the couple can retire; it is what they are buying with each pound of surplus.
Spend and gift is the most lifestyle-forward branch. It uses £5,400/month for comfortable spending, gifts £1,500/month through age 80, and makes a £75k family capital gift. In the base run it finishes age 96 with about £1.42m of pooled capital after keeping a £175k care reserve.
Pension reset assumes the pension pot is too large to leave untouched by default. It lowers core spending to £5,000/month, models £850/month of taxable-withdrawal friction, and keeps gifts smaller. This base run finishes with about £1.52m of pooled capital, so the branch is about gradual drawdown discipline, not a pension raid.
Legacy reserve is the caution branch. It keeps gifts to £450/month, uses £4,600/month of core spending, and sets aside a £275k late-life care reserve. It finishes with about £2.11m, which may leave more assets exposed to future tax, but it protects the surviving spouse and reduces the chance of irreversible gifts becoming a problem.
This path fits couples who realise the goal is not to die with the largest possible pension pot. If the 2027 reform lands broadly as published, preserving the pension solely for IHT reasons may be less powerful than it once was.
The discipline is to keep the gifts affordable and documented. Larger gifts can be advice-sensitive, and a gift that looks tax-efficient can still be a bad plan if it weakens care options, creates family dependency, or leaves the survivor short of liquid assets.
This path starts using pension wealth earlier and treats tax friction as part of the plan. It can make sense where the pension is large relative to ISA and cash, or where the estate would otherwise become pension-heavy at second death.
It is not automatically better. Pension withdrawals are taxable after any tax-free element, and moving wealth from a pension into ISA, GIA, or cash does not make it disappear from the estate. The best version is gradual, tax-band-aware, and reviewed before and after the 2027 implementation date.
This path keeps more money in reserve and accepts that tax may not be the first risk. It suits households with uncertain health, blended-family complexity, uneven beneficiary needs, or a strong preference that the surviving partner never has to rely on heirs for support.
The cost is visible: the household may spend and gift less during the healthiest years. That can be the right trade when care costs, longevity, and future policy changes are more worrying than a neat estate-reduction plan.
Pension-IHT reform: HMRC material says most unused pension funds and pension death benefits are expected to enter IHT scope from 6 April 2027. Scheme-level administration, beneficiary allocation, withholding, and later guidance need verification.
IHT thresholds: the research file records the nil-rate band at £325k and residence nil-rate band at £175k, with unused allowances often transferable between spouses or civil partners. Eligibility, tapering, gifts, reliefs, and second-death timing are fact-specific.
ISA treatment: ISAs remain useful tax shelters while held, but they normally form part of the estate for IHT after death.
Pension withdrawals: the model's tax-friction lines are proxies. It does not calculate personal allowances, tax-free lump sum availability, marginal tax rates, Scotland-specific bands, Capital Gains Tax, or pension death-benefit Income Tax.
Care risk: Age UK's care-cost anchors make a six-figure care reserve reasonable for this kind of stress test. The model does not calculate local-authority means-testing.
Split the £1.25m starting balance into pension, ISA, GIA, and cash before using the result.
Test a lower-wealth version if the DC pension is nearer £500k, and a higher-wealth version if it is nearer £1.5m.
Move the care reserve earlier and raise it if either partner has health concerns.
Change the secure income first. If State Pension and DB/annuity income do not cover most bills, this becomes a retirement-sustainability case before it is an inheritance case.
Mark every exact IHT, gift, pension-death-benefit, and care-funding conclusion as needs verification until checked against the household's documents and the final rules.
