Thesis (Alf’s read): the “1 in 20 estates” figure — the load-bearing defence of inheritance tax — is accurate today and expires within five years on every published projection, because the tax’s design stopped matching the purpose it was built for. A tax defended by a statistic that is about to stop being true has no argument left, which is why the public debate has collapsed into a complaint about the rate.

- Lewis Goodall vs Tory MP on inheritance tax — LBC, uploaded 4 October 2026 (11m40s). Interview with Laura Trott, Conservative shadow minister, from the Conservative conference in Birmingham. https://youtu.be/ANYySsoqzuY
What the clip says
The interviewer does not attack the tax on rate grounds. He states the principle, twice, more clearly than any minister in the clip:
“This is a tax, which is paid by the wealthiest one in 20 estates. You say that you’re the party of hard work. Why should someone earning their money through work pay tax while someone receiving in substantial windfall inheritance pays nothing?”
“You could reduce the taxes on people who are alive and earning simply by keeping some inheritance tax on estates, which is a windfall basically — not on the people who are dead, but on the people who are alive inheriting it, who have done nothing to deserve it.”
The shadow minister’s answer is the whole problem in one sentence:
“I think that it’s important to defend the right of people to hand down stuff to your family and I don’t care how much money that is. It’s a principle thing.”
Asked whether anyone should inherit £10m untaxed, she answers I don’t care how much money that is. The man carrying the tax’s original argument is the journalist; the politician carrying the tax’s future has replaced the argument with a principle about family.
The purpose, stated
- Estate Duty, 1894 (Harcourt’s Budget). A charge on accumulated wealth passed at death. Lloyd George’s 1909 People’s Budget sold death duties as the fairest way to fund social reform, with the explicit aim of breaking up the great landed estates.
- Capital Transfer Tax, 1974-75 (Healey). The high-water mark: cumulative on lifetime transfers, progressive, up to 75%. Redistribution as the design, not a side-effect.
- IHT, 1986 (Lawson). Replaced CTT with a flat 40% charge on death — simpler, and deliberately softer. At the design stage it was intended to catch a small number of large estates.
- The economic statement of it (Mirrlees Review, 2011): inherited wealth is unearned income to the recipient, so tax them — with a generous lifetime allowance — rather than the estate. “Death tax” is a framing error; the honest name is a windfall tax.
- What the tax is for, in three parts: revenue from wealth never taxed as income; a brake on dynastic concentration (the equal-opportunity argument); and the only UK charge on the transfer of wealth at all.
The claim, tested: “1 in 20”
Accurate, and quoted correctly. HMRC, Inheritance Tax liabilities statistics 2023-24 (published 30 July 2026):
| Measure | Figure |
|---|---|
| Estates charged to IHT | 30,400 |
| UK deaths | 644,000 |
| Share of deaths | 4.72% — 1 in 21 |
| HMRC’s own words | ”fewer than 1 in 20 estates, as it has been since 2007-08” — the highest since 2006-07 (5.96%) |
| Total liability | £7.03bn |
| Average bill | £231,000 |
| Average effective rate | 13% (against a 40% headline) |
Three reasons the number is weaker as a defence than it looks:
- It counts estates that paid, not families affected. Anyone who stayed under the line only by planning — gifting, trusts, APR/BPR, spending it — is invisible in it. It measures the unplanned, not the untouched.
- It is a national average over a postcode lottery. London and the South East paid 46% of all IHT from 37% of the payers (11,120 estates, £3.26bn).
- Nobody pays 40%. The average effective rate was 13%. The headline rate is an upper bound on a slice of an estate, not a bill.
The projection: 1 in 10 by 2030
The OBR’s central case is “around one in ten estates liable by 2030-31” — the figure industry commentary repeats (Standard Life; though a Canada Life release prints 8%). The independent and statutory estimates side by side:
| Source | Estimate | Estates/yr | vs today |
|---|---|---|---|
| HMRC, today (2023-24) | 4.72% — 1 in 21 | 30,400 | — |
| HMRC, pension inclusion alone (2027-28) | 6.35% — 1 in 16 | 40,900 | ×1.35 |
| IFS, frozen thresholds (Sep 2023) | ~7% by 2032-33 | 45,080 | ×1.48 |
| Industry “almost 1 in 10” | 8% | 51,520 | ×1.69 |
| OBR headline (2030-31) | ~10% | 64,400 | ×2.12 |
Derived from HMRC: 30,400 taxpaying estates of 644,000 UK deaths (4.72%), plus 10,500 newly liable from the pension change (HMRC, 21 July 2025). Percentage rows computed at 644,000 deaths.
The pension change alone gets to 1 in 16, not 1 in 10. The rest is fiscal drag: the £325,000 nil-rate band and £175,000 residence nil-rate band are frozen to 5 April 2031 (extended a year at Budget 2025), with the £2m taper threshold frozen alongside them, while asset prices rise.
The receipts say the same: £7.03bn (2023-24) → £8.2bn (2024-25) → £8.7bn (2025-26 forecast) → £14.7bn (2030-31) — a doubling in seven years (OBR, November 2025).
The burden is not evenly spread: estates of people dying aged 85 or over paid 56% of the total (£3.97bn of £7.03bn). This is a tax on the very old, concentrated in the south-east, who did not plan.
Why the amnesia is the diagnostic
- The design stopped matching the purpose. A £325,000 threshold frozen since 2009 — 17 years by 2023-24, 22 by 2031 — cannot be sold as breaking up great estates when it catches an ordinary suburban house. The tax stopped reaching dynastic wealth and started reaching homeowners who didn’t plan.
- Once the target changed, the moral argument evaporated. No version of “the great estates must be broken up” survives taxing an ordinary house, so the debate degrades — correctly — into a complaint about the rate: 40% is crazy.
- The extraction has gone quiet. Nothing in the last three years was argued for out loud: thresholds frozen, reliefs capped (£2.5m APR/BPR from April 2026), pensions inside the estate from 6 April 2027, non-dom trust routes closed. Delivered by technical annexe and announced by nobody.
- Even the abolition camp concedes the ground. Badenoch calls the tax “immoral” and says “the richest don’t pay them, it’s just the middle class”. That is true — and it is an argument for reforming the tax back toward its original design (broad base, low rate, hard to avoid), not necessarily for abolition. Nobody in the clip, or at that conference, makes that argument.
Where each party actually is
(October 2026. Policy positions move — re-check before relying on any of this.)
| Position | Is that “mitigation”? | |
|---|---|---|
| Conservatives (Badenoch) | Reviewing reduction or abolition; called IHT “immoral”; no commitment until it can be funded | Yes — direction of travel is abolition |
| Labour (Burnham) | Bands frozen to 2031, pensions in scope April 2027, APR/BPR capped at £2.5m. Burnham’s own earlier suggestion: 10% on all estates, no allowance | No — the opposite. Broadening the base. His 10%-on-everything idea would raise more from most estates |
| Reform UK | Abolish IHT below £2m; 20% above | Not the status quo. Abolishes for nearly everyone while keeping the charge on the largest estates |
| Greens | Replace death taxes with an annual wealth tax above £10m | Neither — an explicit anti-concentration alternative |
The direction of travel is therefore not “Labour and Tories both mitigating”. It is: the Tories abolishing, Labour extracting, and Reform alone keeping a charge on the largest estates while ending it for ordinary families. Reform’s own Treasury spokesman then attacks Tory abolition as “a benefit for the wealthiest 5 per cent” — a contradiction no party can resolve without the purpose it has forgotten.
Worth noting: Burnham’s 10%-with-no-allowance is the closest thing on the table to the 1894 aim — a broad, low-rate charge on inherited wealth that is hard to dodge. Not mitigation; the purpose rediscovered by accident.
My assessment (Alf)
The shadow minister’s “I don’t care how much money that is” is an honest answer to the wrong question, and it is the most useful thing in the clip: nobody in that exchange could say what inheritance tax is for. The interviewer knew. The politician had a principle about family instead. The rate debate fills the vacuum.
On the numbers, the claim holds up on both counts: the 1-in-20 figure is real and quoted accurately, and it is heading to roughly 1 in 10 by 2030-31 on the OBR’s central case. The honest range is 7-8%, with 1 in 16 already locked in by the pension change; the OBR’s 1-in-10 needs fiscal drag to do the rest.
Where I would push back: 40% is not the scandal, and never was. The average estate pays 13% — around a third of the headline rate. The scandal is a flat high rate bolted to a frozen low threshold: punitive on small unplanned estates (the £2m taper band produces marginal rates near 60%), porous for anyone with advice and seven years of time. That combination is why the tax satisfies nobody — too costly for the middle, too avoidable for the top, unable to raise what its defenders claim it should.
Which makes the party positions less interesting than they look. Abolition and 10%-on-everything are both answers to a question nobody is asking — the first abandons the purpose, the second accidentally restores it. The only party arguing from the stated purpose, bluntly, is Reform: keep a charge on the largest estates, drop it for everyone else. That may be tactically cynical, but it is the position the tax’s own history supports.
