Executive Summary

The UK's tax system rests on foundations that are giving way. Income tax and National Insurance, both taxes on work, provide about 55% of the tax HMRC collects. Artificial intelligence threatens that base, and the wealthiest already take much of their return as lightly taxed capital instead of income. Work is taxed heavily, while the asset wealth the system barely touches keeps growing. The UK isn't facing a future fiscal crisis so much as living through the early stages of one.

This pillar's answer is a 95% inheritance tax on all wealth at death, applying to everyone, with no exemptions by asset class, and its revenue used to cut income tax, starting with the lowest earners. Nobody is stopped from building extraordinary wealth in their lifetime, and the incentive to earn, build, create and invest gets stronger. What goes is the ability to hand a permanent head start to descendants who did nothing to earn it. The Monopoly board resets between generations; the game carries on.

The pillar makes five arguments: - The shift is arithmetic, not ideology. The current tax base is eroding while the alternative base grows. - The fiscal case is real but limited. The baby boomer transfer now under way, roughly £100–115bn a year and rising, can pay for a substantial, permanent income tax cut, but not for the whole of income tax. - The design works with human nature. Spending down an estate during life is the intended response, not a loophole. - The transition can be made credible. It has real difficulties, which the Gaps Register sets out in full. - The timing matters. The reform fits this technological and demographic moment, and the window for it will not stay open.

Key Proposals

1. The Diagnosis

1.1 The Meritocracy That Doesn't Exist

The main defence of today's distribution of wealth is that it was earned: the system rewards enterprise, effort and innovation, and taxing the results punishes the behaviour that creates prosperity. At the scale that matters, the evidence says otherwise.

That 60% figure, for billionaire wealth that came from inheritance, monopoly position or political connections rather than enterprise, comes from Oxfam's January 2025 analysis of where billionaire wealth comes from: 36% inherited, 18% from monopoly power and 6% from cronyism.¹ The categories are Oxfam's, and the cronyism share in particular depends on how it is defined, but the inherited share alone is more than a third. If the figure is anywhere near right, it undercuts the main moral defence of extreme wealth concentration, which depends on the wealth having been earned.

In UBS's 2023 report, for the first time in the nine years it had run, new heirs gained more billionaire wealth than new self-made billionaires: 53 heirs inherited $150.8 billion, against $140.7 billion for 84 people who built their fortunes.² The 2024 report found the pattern reversed, so this is a sign of the coming transfer between generations rather than a settled trend. Oxfam found that every billionaire under thirty inherited their fortune.¹ The meritocracy Britain likes to celebrate describes the system we tell ourselves we have. That gap matters more than it sounds, because it lends moral cover to an arrangement the evidence doesn't support.

The concentration is speeding up. The wealthiest 0.001% held 3.7% of global wealth in 1995 and hold 6.1% today, and the top 1% now hold 37% of it.⁴ Enterprise doesn't produce numbers like these. They come from a system in which asset values compound, inheritance passes accumulated advantages on intact, and the political structures that might redistribute either have been captured by the people who benefit.

This bears directly on the case for Economic Renewal. The most common objection to a 95% inheritance tax is that it would destroy the incentive to build wealth. That objection only works if the wealth being passed on was built by the people who would lose it at death, and increasingly it wasn't. Dynasties, more than entrepreneurs, produce the extreme wealth this tax would capture, and that is the problem it is designed to solve.

1.2 The Fiscal Problem

Income tax and National Insurance together raised £475 billion in 2024/25.⁵ Every pound depends on someone receiving a wage, a salary or other employment income. When an AI system replaces a worker, the income tax and NI that worker paid disappear at once, and keep disappearing. The productivity gain goes to the business using the AI. Corporation tax should in theory capture some of that gain, but spending on AI is often fully deductible, which cuts taxable profits at exactly the point a business is building its advantage.

So the tax base is being worn away from three directions at once. AI shrinks the amount of wage income subject to income tax and NI. Wealthy taxpayers reclassify returns away from income and into capital, where the tax is much lighter. And AI-generated corporate profits are routed through low-tax jurisdictions or sheltered by investment deductions. The Tax Avoidance pillar sets out each of these mechanisms separately. Together they are hollowing out a tax base that the current design can't protect, because it was built before any of them operated at scale.

The wealthiest estates pay well below the 40% headline inheritance tax rate.⁷ Business Property Relief alone nearly halves the effective rate for estates over £30 million, from 23% to 12%, and more than two-thirds of that relief goes to around 400 estates a year. Agricultural Property Relief, spousal exemptions, lifetime gifts, pension wealth, AIM share wrappers, offshore trusts, freeport storage of art and collectibles, and the further routes the Tax Avoidance pillar lists shelter still more. The 40% rate isn't paid by the estates holding the most wealth. It's paid by the estates whose planning was incomplete.

This is the system the Generational Reset proposes to replace. Wealth isn't the problem. A tax system that leans on a shrinking base while a growing one goes largely untouched can't last. It's in managed retreat, buying time until the arithmetic forces a reckoning on worse terms than are available now.

1.3 Where the Money Goes: Who Captures the Gains from AI

The erosion of the income tax base is often discussed in the abstract. In practice it has a specific mechanism, a direction of travel and identifiable beneficiaries. Who captures the gains from AI is the most important single point in this pillar, because it explains both why the problem will grow and why the time to act is running out.

When a UK business uses AI to automate a job a UK worker used to do, a chain of consequences follows. The worker loses income and stops paying income tax and National Insurance. The business gains: lower costs, higher margins or more output. But in most cases the AI system isn't built, owned or taxed in the UK. It comes from American technology companies (Microsoft, Google, Amazon, Meta, OpenAI), whose models are trained on American infrastructure, whose intellectual property sits in American or Irish corporate structures, and whose returns go overwhelmingly to American shareholders and a small number of executives and founders.

It happens in three steps. First, a UK worker is displaced, and their income and the tax it paid leave the UK economy. Second, the value that used to be paid as wages moves onto the balance sheet of the business using the AI. Third, the subscription or licence fee for the AI system leaves the UK altogether, going to the US company whose model is being used. The net effect is a transfer of value from UK wages to US capital. At scale, it pumps money out of the UK economy and into the hands of a handful of American owners.

This is already happening. Microsoft's Copilot is built into the Office software most UK employers already pay for, and the government trialled it with 20,000 civil servants in 2024. Google's Gemini sits inside productivity tools used by millions of UK workers. Amazon Web Services hosts the AI infrastructure UK businesses run on. Every subscription, API call and enterprise licence sends money from UK economic activity to American owners, through corporate structures designed to minimise the tax any country collects along the way.

Transfer pricing makes it worse. US technology companies hold their intellectual property (the models, the training data, the software patents) in low-tax jurisdictions such as Ireland, Luxembourg and the Netherlands. Their UK subsidiaries pay licence fees to those holding companies. The UK absorbs the job losses, but the Exchequer doesn't capture the corporate gain, because the gain is booked in Dublin or Amsterdam at a fraction of the UK corporation tax rate. The OECD's 2021 global minimum tax sets a 15% floor, but that still leaves a large gap against the UK's 25% headline rate⁸, and how the minimum tax works in practice is still disputed.

The sums committed make the point. Amazon, Microsoft, Alphabet and Meta plan to spend about $725 billion on capital investment in 2026 alone, mostly on AI, up from about $410 billion in 2025.⁹ That will produce ever more capable AI systems, used worldwide, whose returns go overwhelmingly to their shareholders. The largest shareholders of Microsoft, Alphabet, Amazon, Meta and Nvidia are mostly the same American asset managers (BlackRock, Vanguard, State Street), holding diversified positions for their clients. UK pension funds own a slice. But control, founder equity and the outsized returns at the top of AI's value chain are overwhelmingly in American hands.

Few if any people in the UK have yet become billionaires mainly through artificial intelligence. Several people in the United States already have fortunes measured in hundreds of billions, and some are expected to pass a trillion within this decade. The gap reflects where the AI companies were founded, where the models were trained and where the intellectual property is held, and it will widen with every year of AI adoption unless something specific changes it.

1.4 What This Means for the UK Specifically

The UK is especially exposed, for three reasons.

First, the UK economy leans heavily on the service industries where AI is replacing human thinking work fastest: financial services, professional services, law, consulting and back-office operations. The UK has a large workforce in office-based knowledge jobs and relatively little of the manufacturing, engineering or deep-tech industry that could offer displaced workers somewhere else to go.

Second, the UK has no significant independent frontier AI company. DeepMind was founded in London, but Google has owned it since 2014. Where AI's productivity gains would be owned was decided years ago, in Silicon Valley and Seattle rather than London or Manchester. Germany still owns much of its industrial machinery, and France has Mistral as a European challenger; the UK mostly buys American AI and makes little of its own. Most of every pound UK businesses spend on AI subscriptions leaves the country.

Third, the UK's tax system is badly designed for this. Income tax and NI tax the thing AI is removing: wages. Corporation tax is easily minimised by the companies capturing AI's gains through transfer pricing. Capital gains tax charges the returns on AI investment at much lower rates than earned income. As AI spreads, the system as designed will collect less from displaced workers, from lightly taxed corporate profits and from lightly taxed capital returns, while more of the value produced in the UK flows abroad.

The same point explains the political urgency. The UK can shape its response to AI-driven wealth concentration only before that concentration starts reinforcing itself. American technology companies are already using AI at a scale that widens their lead every year. UK businesses, workers and government on the receiving end have a shrinking period in which reform is still an alternative to managed decline. This pillar argues that the inheritance tax reform is the right response, but the problem is getting worse faster than the current political system can react.

2. The Steel Man: The Strongest Case Against Reform

Each part of that case deserves an answer.

On reform already under way: the changes cited are real, but they don't go far enough. Raising CGT from 20% to 24% still leaves it 21 points below the top income tax rate. Carried interest reform took decades of lobbying and three governments. The pension inheritance tax change is still contested in how it will work. These close particular gaps; they don't redesign the system. The Tax Avoidance pillar shows that every margin of the system is already exploited by people with the resources to do it. Gradual reform closes small gaps a little at a time while the base keeps shrinking.

On the Swedish precedent: Sweden's inheritance tax had a 70% top rate on the largest estates from the late 1950s¹⁰, and it fell in stages rather than in one slow fade. Valuation reliefs for family firms, introduced from the 1970s, cut the effective rate on the largest fortunes while middle-class heirs still faced high rates, which undermined the tax's legitimacy. A parliamentary majority then cut the top rate to 30% in 1992, as part of a wider push to reduce taxes on capital. Bequests to spouses were exempted in 2003, and the tax was abolished entirely in 2004.¹⁰ This is the warning, and the Generational Reset takes it seriously. It treats the risk of a tax being hollowed out after it's passed as one of the biggest design problems the reform faces, and proposes specific defences: constitutional rate protection that needs a supermajority to change; an independent inheritance tax authority modelled on a central bank rather than a government department; real-time public disclosure of every estate assessment and relief claimed; and an automatic escalation if the effective rate falls below the legislated rate by more than a set margin. Sweden's experience argues for better institutional design, not for giving up on the reform.

On the arithmetic: the steel man is right, and this pillar was corrected on 14 October 2026 to say so. It used to claim that enough wealth passes between generations to replace income tax entirely, after a 15–25 year transition financed by borrowing. The real transfer, roughly £100–115bn a year now, can't do that (§4.1). It can pay for a substantial, permanent income tax cut, made only as fast as the revenue arrives, so no transition debt is needed. And the revenue is only part of the case for the machinery; the other part is limiting inherited advantage (§3), which a smaller income tax cut doesn't weaken. What the reform needs is political will that lasts across several parliaments, which is why the Political Renewal pillar has to come first.

3. The Mechanism: Reset the Board, Keep the Game

The model changes how the system works; it isn't designed to punish anyone. That matters because the most common misreading of the proposal is that it attacks wealth creation. It does the opposite.

Income tax is cut, as far as inheritance tax revenue actually pays for, starting with the lowest earners. The incentive to earn, build, invest and create during a lifetime gets stronger. Someone who builds a business, learns a trade, writes software or practises medicine keeps more of what they earn. The weight of the tax system moves from the moment wealth is earned to the moment it passes to someone who didn't earn it.

What changes is what happens when wealth passes between generations. Whatever someone accumulates in a lifetime, through any mix of effort, talent, luck and circumstance, passes to the next generation taxed at 95%. The dynasty stops compounding. The Monopoly board resets between games. The game itself, and the incentive to build, earn and create, carries on unchanged, because the builder keeps the full reward of building throughout their life.

What This Actually Changes

Before the mechanics, it helps to be clear about what kind of change this is, because arguments about rates and thresholds can hide it. This is a proposal to renegotiate the basic deal between a person, their work and the state, not just to swap one tax for another of similar size.

Income tax was reintroduced in peacetime by Robert Peel in 1842 and has been levied ever since: formally "temporary", renewed by Parliament every year, in name only. Under that system, everyone who works, builds or invests hands part of it to the state as they go, on the salary, the dividend, the capital gain and the profit. Under this proposal that share shrinks. Less of what someone earns from their own work, business or capital goes to the state while they hold it, and much more of the state's claim arrives at the one moment the wealth stops being anyone's active project and becomes someone else's unearned inheritance. That is a different balance between the individual and the state from the one Britain has run for almost two centuries: a change in where the relationship puts its weight, not just a change of rates within it.

The effects reach beyond the tax bill. Money that would otherwise sit as a largely idle, growing claim on future output, held for descendants who haven't earned anything yet and some who aren't yet born, becomes the owner's own money to spend, invest or give away while they're alive to choose. Section 3.1 explains why that produces more real economic activity than the current system. Capital in active use, whether a new factory, a research programme or higher personal spending, moves through the economy in a way that capital parked in a trust for the next generation doesn't. A system that now rewards keeping wealth still would reward putting it to work, the same incentive the income tax cut creates for labour, applied to capital as well.

The fairness case follows from something this pillar has already shown. Section 1.1 found that most of the wealth this tax would reach wasn't earned by the people who hold it now: 60% of billionaire wealth comes from inheritance, monopoly or cronyism rather than enterprise, and in UBS's 2023 report, for the first time, new heirs gained more billionaire wealth than new self-made billionaires. A system that takes less of what a person builds, earns or invests in their own life, and almost all of it once it passes to someone who didn't build it either, isn't redistributing what people have earned. It declines to let unearned advantage compound indefinitely through generations who never had to prove they could earn it. That is a value judgement this project makes openly; the evidence alone doesn't settle it. A reader who gives more weight to keeping family wealth together, whoever built it, isn't wrong about the facts, just weighing them differently. Either way, this is an argument about the shape of British society two generations from now, as much as about which tax raises how much.

3.1 Why Spend-Down Is the Point

The objection that wealthy people will simply spend down their estates to escape the 95% rate misreads the model, because spending down is how it's meant to work. When someone who would have left £50 million to their children spends it during their life instead, on a new business, on philanthropy, on consumption or on productive investment, that money goes back into the economy. It creates jobs, funds innovation and builds things. Money sitting in a trust for grandchildren who didn't earn it does none of that.

Spending down isn't tax avoidance, because it doesn't hide assets from the state. It puts them to use, and the Generational Reset is designed to encourage exactly that.

3.2 Directed Spend-Down: Working With Human Psychology

Cutting income tax weakens the main lever governments now use to steer wealthy people's spending towards good causes, because tax relief is worth less when rates are lower. The replacement isn't a cleverer relief scheme but legacy, status and meaning, which are stronger and longer-lasting motives than any tax break.

Carnegie built libraries, and his name is still on them 120 years later. Wanting to be remembered, to leave something that outlasts your own life, is one of the strongest human motivations, and the model works with it.

• Lifetime Legacy Credits: permanent naming rights for defined social investments such as hospitals, schools, research institutes and cultural buildings. The reward is lasting recognition, not tax relief.

• Directed Investment Vehicles: ring-fenced funds in green energy, social housing and public infrastructure that pay competitive market returns, so money spent down goes into productive assets instead of sitting idle.

• Outcome-Linked Bonds: private capital pays for defined social outcomes, and the state pays a return only when those outcomes are independently verified. This already works at smaller scale and is ready to expand.

3.3 The Norway Analogy: The UK's Second Chance

Norway and the UK both found large North Sea oil reserves in the 1970s, and both had to decide what to do with the money. The UK collected more than £330 billion in North Sea tax revenue between 1968 and 2017, adjusted for inflation, on a Financial Times estimate, and the industry has cost the Exchequer more than it raised in some years since.¹¹ That money paid for day-to-day government spending and tax cuts. It was real, and it was spent. Norway put its windfall into a sovereign wealth fund, worth about $2.4 trillion (roughly £1.7 trillion) in June 2026 and invested for future generations.¹²

The UK can't get its North Sea money back. But it is about to see the largest transfer of wealth between generations in its history. The baby boomer generation holds much of the UK's £10.8 trillion of household wealth, and over the next two to three decades, as that generation dies, the wealth will pass on. The transfer will happen either way. What's undecided is whether it entrenches ever-greater inherited inequality, or whether part of it is captured and saved the way Norway saved its oil revenue.

3.4 The Argument, Made Explicit

Sections 1 to 3.3 make the case for the 95% inheritance tax in ordinary prose. This section restates it step by step, following How We Reach Conclusions, so the reasoning can be checked rather than taken on trust. Nothing here is new: each stage restates what Sections 1–3 and the Tax Avoidance, How Tax Works and Revenue Architecture pillars already establish, with the confidence of each stage labelled.

4. The Transition: How Implementation Would Work

The transition isn't simple, and the Gaps Register sets out the known difficulties. This section explains how implementation would work, what the risks are, and how the design responds to them.

4.1 The Financing Gap

Income tax and NI together raise £475 billion a year. Corrected 14 October 2026: this section used to rely on an annual wealth transfer of £200–400bn now, rising to £350–450bn at the boomer peak, and on that basis treated replacing income tax entirely as a transition problem: a gap of £1–4 trillion to be financed over 15–25 years. No source supports those transfer figures. The best available estimates put transfers between generations at roughly £100–115bn a year now. Cebr's projection for Kings Court Trust puts total transfers at death and in lifetime gifts at £115bn in 2027, and the Resolution Foundation, using HMRC data, put estates passing on death at £87bn in 2014–15 and expects inheritances to double over the next two decades. On that projection, transfers rise to perhaps £200–355bn a year by the 2040s in cash terms.¹³

[ANALYSIS] On this project's own arithmetic, a 95% tax on every pound transferred would raise roughly £95–110bn a year today, about a fifth of the £475bn. That assumes no threshold, no spousal exemption, no avoidance and no spending down, all of which this pillar either proposes or expects. By the 2040s the transfer may be two to three times larger in cash terms, but income tax and NI grow in cash terms too (to roughly £600bn by 2030/31 on current forecasts), so the share hardly changes. Actual revenue would come in below this ceiling, and the better spending down works, the smaller the base becomes. Inheritance tax can't match income tax. The shortfall is permanent; no transition period closes it.

So the proposal is not abolition. It is a substantial, permanent shift in the tax base: income tax cut by as much as proven inheritance tax revenue pays for, which on these numbers means up to about a fifth of today's income tax and NI at the theoretical ceiling and less in practice. The cuts go to the lowest rates first, and the rest of income tax stays.

For Stage 1 specifically: applying the proposed 60–70% rate to HMRC's own 2023–24 data for estates valued above £2 million gives roughly £10–15bn a year, a small fraction of the £475bn. The full working, and the assumption that drives most of that range (whether the spousal exemption survives Stage 1), is in Revenue Architecture §8.1. The consequence is that in Stage 1's 5–7 year window, inheritance tax pays for only a small cut. Almost all of the work in those early years falls on the other two mechanisms below.

Three mechanisms in combination:

• Phased income tax reduction: cut income tax rates gradually over 15–20 years, in step with rising inheritance tax revenue. This is the safest option for the public finances, but it needs political will that lasts across several parliaments, which is why Political Renewal and independent institutions have to come first.

• Transition bonds: borrow against proven future inheritance tax revenue. The size and timing of the baby boomer generation are well known, which makes its transfers easier to forecast than most tax revenue. UK debt is already about 94% of GDP, and with no permanent gap to fill, these bonds have a narrower job than first proposed: bringing forward income tax cuts that proven inheritance tax revenue will pay for later.

• Sovereign wealth fund: not a new institution, but Public Debt's own Sovereign Wealth Mechanism (Reform 4). From Stage 2 it receives a set share of inheritance tax receipts as a second funding stream, alongside its original revenue from depleting assets, to smooth this pillar's uneven year-to-year receipts. It can't fill the gap by itself, but the long-term design depends on it.

4.2 The Cross-Pillar Impact Map

This proposal doesn't stand alone. Other pillars make claims about what the 95% inheritance tax delivers, what its revenue pays for and which mechanisms it shares, and those claims don't all agree with each other or with this pillar. They're set out here so readers don't have to find the conflicts themselves:

None of this sinks the underlying case. A reform touching this much of the tax base was always going to produce claims in different pillars, written at different times, that need reconciling. All four items this section originally flagged have now been dealt with, though in different ways. The Public Debt contradiction is fully fixed (one SWM, with inheritance tax receipts as a second, smoothing stream; see §4.1 and §8), and so is the British Wealth Fund overlap (Economy's offshore wind revenue now a third stream into the same SWM). Agriculture and the Demographics and Welfare revenue claims are linked up but not fully resolved. Agriculture's §5 now names the reform and points to §4.3's general protections, while saying they're untested for farmland. Demographics' early-years idea is now correctly presented as its own proposal and marked as unfunded, because this pillar's revenue is already fully committed to cutting income tax. That underlying fact, that there's no spare inheritance tax revenue in this project's numbers, can't be fixed by a cross-reference. It would need either a larger revenue estimate than the Numbers Ledger supports or a separate funding source, and this project has proposed neither.

4.3 The Valuation Architecture

At 95%, contesting the valuation becomes the single most valuable thing any significant estate can do, because every pound sheltered saves 95p. The current 40% rate already falls to 12% in practice for the largest estates once Business Property Relief is applied. At 95%, the avoidance industry would operate on a scale never seen before.

Four design requirements follow. They are requirements, not aspirations:

• Safe harbour valuations: HMRC publishes standard valuation multiples for common types of private business. Estates can accept them or contest them, but contesting triggers a full audit and litigation costs, set so that contesting costs more than a lower valuation could save.

• Independent valuation panels: valuers have no financial relationship with the estates they assess. The model is the planning inquiry process, with panel members rotated independently of government.

• Equity stake mechanism: for illiquid assets the state takes a share of ownership instead of cash, so a family business needn't be sold, and its stake is repaid from future profits. This is deferred payment secured against productive assets, not confiscation.

• Staged payment over 10–20 years: for assets so illiquid that neither cash nor an equity transfer is immediately workable. This reduces the risk of forced sales while keeping the tax due.

4.4 Constitutional Rate Protection

The Swedish precedent is the failure this design has to prevent: a 70% top rate from the late 1950s, undermined by valuation reliefs for family firms from the 1970s, cut to 30% by a parliamentary majority in 1992, with spousal bequests exempted in 2003 and the tax abolished in 2004. Sweden shows both of the ways a tax like this can fail. The slow erosion through reliefs and valuations, which came first, is what the independent valuation system and real-time disclosure are meant to stop. The 1992 cut is what "a simple parliamentary majority cannot quietly reduce it" is meant to make much harder, though in UK law it can't be ruled out (see below). The pattern is familiar: reformers win the legislative battle, and the wealthy then spend their resources on implementation, through lobbying regulators, litigation, campaigns for wider reliefs and the gradual capture of HMRC's enforcement bodies.

Four defences:

• Constitutional rate protection: the inheritance tax rate set in a constitutional or quasi-constitutional document that needs a supermajority to change, so a simple parliamentary majority can't quietly reduce it. In UK law this is a strong political barrier rather than a legal guarantee, as the next section explains.

• An independent inheritance tax authority: a body that implements the tax with real independence from government, modelled on an independent central bank rather than a government department, with its board appointed through a citizens' assembly instead of by ministers.

• Real-time public disclosure: every estate assessment, every relief claimed and every valuation published as it happens, so the gap between the headline and effective rates is always visible, and always politically costly to widen. What is published, and what isn't, is set out below.

• A movement that stays organised: the movement that wins the legislative battle has to stay organised through implementation instead of disbanding after an election. The digital organising that won the argument has to be kept going to defend how it's carried out.

What Earlier Inheritance Taxes Show

Gap 9 in the Gaps Register asks how strong taxes on inherited wealth have been diluted before, so the design can be tested against what actually happened. Four cases, including Sweden's above, show four different routes.

• UK estate duty, 1894 to 1975. By 1969 the top marginal rate was 85%, capped at 80% of the estate. But the duty fell only on what someone owned at death and on gifts made shortly before it (within three years, extended to five in 1949 and seven in 1969), and wealth held in discretionary trusts escaped the charge when a beneficiary died until the 1969 Budget moved against it.¹⁴¹⁵ Families and businesses arranged their affairs around the tax; historians link it to the restructuring of British family firms in the 1940s and 1950s.¹⁶ The duty was eroded less by rate cuts than by routes around the charge.
• Capital transfer tax, 1975 to 1986. Estate duty's replacement closed the main route by taxing gifts made at any point in life, at rates up to 75%. In 1986 an ordinary Finance Act reopened it: gifts to individuals became "potentially exempt", free of tax if the giver survives seven years, and the tax was renamed inheritance tax, with a single 40% rate following in 1988.¹⁷ The quip often attributed to Roy Jenkins, that it had become a voluntary tax "paid by those who distrust their heirs more than they dislike the Inland Revenue", dates from this period.
• US federal estate tax. In 2001, estates above $675,000 paid up to 55%. Successive ordinary laws raised the exemption, cut the top rate to 40%, repealed the tax entirely for 2010, and from 2026 exempt $15 million per person.¹⁸ No relief or loophole was needed: the tax was legislated away in plain sight.
• Sweden, described above: reliefs for family firms first, then a rate cut by simple majority in 1992, then abolition in 2004.

Each route corresponds to one of this design's defences, with differing confidence:

The hard part: what "constitutional protection" can mean in the UK. The UK has no codified constitution, and under parliamentary sovereignty a later Parliament can normally undo anything an earlier one passed, by a simple majority. Recent experience shows how fragile statutory locks are. The Fixed-term Parliaments Act 2011 required two-thirds of MPs to call an early election; in 2019 Parliament passed a one-off Act by ordinary majority to hold one anyway, and in 2022 it repealed the 2011 Act outright. The European Union Act 2011's referendum lock was repealed in 2018.¹⁹ Some judges have suggested, without deciding, that Parliament might be able to bind the way future laws are made, but that idea is untested.²⁰ So in practice the protection proposed here would be a strong political and procedural barrier (a statutory supermajority or referendum requirement, the independent authority and published estate data), not a legal guarantee. It would raise the cost of cutting the rate, as the 2011 Act raised the cost of an early election, without making it impossible. A firmer guarantee would need the wider constitutional reform that Political Renewal argues for, and this pillar can't assume it will happen.

What Disclosure Costs, and Where It Stops

Publishing every estate as it is assessed has a real cost, and it falls on identifiable people. Once an estate is published, its heirs are known to have received a large sum. That is a privacy loss for the family, a security risk at the top of the wealth scale (kidnapping, extortion and targeted fraud are real concerns at this level), and, where an estate includes a private company, a loss of commercial confidentiality to competitors.

The design therefore publishes estates by name, but within limits:

• Published: each estate's total valuation, every relief claimed and its value, any valuation that was contested and how it was settled, and the tax paid, linked to the grant of probate. In England and Wales the grant, any will and the estate's value are already public records that anyone can look up, so naming the estate adds little that isn't already available; what it adds is the tax treatment.²¹
• Not published: itemised holdings, addresses, where physical assets such as art are kept, bank and account details, and how the estate is split between individual heirs.
• Who looked: looking up an individual estate needs a verified login, and the estate's representatives can see who searched for it. Norway, which publishes every taxpayer's income, wealth and tax, added this in 2014; searches fell to about a tenth of their previous level.²²
• Aggregates: effective rates, reliefs and contested valuations are also published by estate size, so the gap between the headline and effective rates can be tracked without looking up any individual.

This is a value judgement, and the project makes it openly. Erosion of a tax happens one relief and one valuation at a time, so accountability needs estate-level data, not just totals. The project judges that worth a bounded loss of privacy for the heirs of the largest estates. A reader who gives more weight to family privacy, and would publish only aggregates, isn't wrong about the evidence; they weigh it differently.

Is it lawful? This is this project's reading of the law, not legal advice, and any legislation would need proper legal review. Three points matter.

• Data about the dead isn't personal data. The UK GDPR and the Data Protection Act protect living people only, so an estate's own valuation, reliefs and tax are outside data protection law.²³ But anything that identifies a living person is inside it: a surviving spouse, heirs, executors, and the co-owners of a family company whose own stakes could be worked out from the estate's valuation. Publishing that needs a clear lawful basis in statute, and has to be necessary and proportionate.
• Tax information is confidential by law. HMRC officials commit a criminal offence if they disclose information about an identifiable person without a statutory gateway.²⁴ The Act creating the independent authority would have to authorise publication explicitly, field by field.
• Publishing everything to everyone can fail a proportionality test. In 2022 the EU's highest court struck down unrestricted public access to registers of company ownership as a serious and disproportionate interference with private life.²⁵ That ruling doesn't bind the UK, but UK courts apply similar reasoning under Article 8 of the European Convention on Human Rights. The limits above (no itemised holdings, addresses or heirs' shares; verified, logged lookups; aggregates for anyone who only needs the pattern) are the kind of safeguards that make a proportionality case.

Two further safeguards follow. Company valuations should be published as the value of the estate's own holding, not in a form that reveals the stakes of living co-owners. And living relatives should be able to apply to withhold specific details where there is a real security risk, in the same way that people can already apply to have their home addresses protected on the Companies House register.

4.5 The Two-Stage Implementation Path

There's a sequencing problem. You can't prove inheritance tax revenue will arrive without bringing in the tax, and you can't responsibly bring in the full tax without proof of the revenue. The most workable path is therefore two stages.

Stage one: introduce a significant but not maximum reform, 60–70% on estates above £2 million with real measures to close avoidance routes. No income tax cut yet. Over 5–7 years, build up the revenue data, administrative systems, valuation methods and public acceptance together. Gather real evidence on how people respond. Build the HMRC capacity the full model needs. Put the constitutional protections in place before the full rate applies.

Stage two: use the proven evidence and the institutions now in place to make a credible case for the full rate, and begin cutting income tax in step with rising inheritance tax revenue. This adds 5–10 years to the timeline, a real drawback when urgency is the central argument. But it breaks the chicken-and-egg problem, and without a crisis forcing faster action it's the most workable route.

What Triggers Stage Two

Stage Two shouldn't begin because a government wants it to, or because a fixed number of years has passed. It should begin when Stage One has produced evidence that the design works. That evidence has five parts, and all five need to hold. The thresholds below are this project's own judgement, set out so they can be challenged.

Test 1 is the falsification test in §3.4 stated as a number. If it fails, Stage Two doesn't just wait: the design needs revising, as the Kill Sheet in §10 says.

Why it takes five to seven years. Inheritance tax evidence arrives slowly. HMRC published its figures for deaths in 2022 to 2023 in July 2025, more than two years after that tax year ended,²⁶ and contested valuations take longer still. So by the end of Stage One's fifth year there would be about three years of settled data, the minimum the tests need. The 5–7 year window is roughly how long the evidence takes to exist.

Who judges. The Treasury shouldn't mark its own homework. The closest UK precedent for a policy decision gated on published tests is Gordon Brown's five economic tests for joining the euro, set in 1997. The Treasury, the department advising the minister who would decide, assessed them itself, and in 2003 the deciding judgement was that it "could not be confident" the economy was flexible enough.²⁷ Whatever the merits of that conclusion, it was impossible to separate from the politics. Here the revenue and avoidance tests go to the OBR, and the enforcement tests to the National Audit Office, each reporting to Parliament every year. The model is the Climate Change Act 2008: an independent committee reports on progress each year, and the government must lay a formal response before Parliament by a fixed deadline.²⁸ Stage Two's tests would work the same way, with the first report due in Stage One's third year.

What the tests can and can't do. Meeting the tests allows the move to Stage Two; it doesn't force it. Parliament still decides, and under UK parliamentary sovereignty no earlier law can stop it deciding otherwise (§4.4). The tests make a decision visible: a government that moves to 95% with the tests failed, or refuses with them all met, has to say why against published evidence. There are five tests because one indicator can mislead. In August 2013 the Bank of England said it wouldn't raise interest rates until unemployment fell to 7%, which it expected in 2016. Unemployment approached 7% within six months, and the Bank moved to a wider set of indicators.²⁹ A single number can be passed for the wrong reasons; five together are harder to meet by accident.

5. Closing the Avoidance Routes

The anti-avoidance design is what holds the policy up. Without it, the reform would produce a high headline rate and a low effective rate, exactly what the Tax Avoidance pillar shows happening under today's 40% system. Each route below needs a specific law to close it, not a general promise to tackle loopholes.

5.1 Asset Classes Requiring Specific Treatment

The principle, both philosophical and administrative, is that the tax applies to every kind of asset. Applying it to everything means dealing with each asset class on its own terms, because each raises different valuation and enforcement problems.

• Property: can't move, is registered, and can be taxed without international cooperation. The most straightforward asset in the model.

• Registered shares and bonds: registered, traceable and taxable. UK-registered shares can't be deregistered. Offshore holding structures need the citizenship-based taxation described below.

• Private companies: valuations will always be disputed. The equity stake mechanism and safe harbour valuations are designed for exactly this.

• Intellectual property: patents, music catalogues and brands have no consistent valuation method at scale. HMRC would need sector-specific valuation frameworks, developed with independent experts.

• Crypto and digital assets: designed to resist oversight, so they need their own legislation: reporting obligations tied to citizenship, disclosure requirements on exchanges, and undisclosed holdings treated as taxable income.

• Art and collectibles: thin markets, subjective valuations and easy to move. Substance-over-form rules would apply to everything held in foreign freeports by UK-resident owners, since where an object is physically kept doesn't change who owns it.

• Pension wealth: the October 2024 decision to bring pensions into inheritance tax from April 2027 is the precedent. The 95% model needs full inclusion, with primary homes and modest pension savings protected below the threshold.

• Foundations and charitable trusts: the route by which a family keeps control of "donated" wealth across generations without it ever formally passing to an heir. The required treatment is a mandatory spend-down within one generation of the founder's death, with no family board control after that. A real philanthropic foundation can still direct its money during that period, but it can't serve as a permanent, family-run vehicle that avoids the transfer altogether.

5.2 The Global Coordination Requirement

The biggest avoidance route is moving citizenship or assets to countries that don't take part. The design answers that with citizenship-based taxation: UK citizens stay liable for inheritance tax on their worldwide wealth wherever they live when they die, and renouncing citizenship triggers the tax. This is the US model, the most comprehensive citizenship-based tax system among developed countries.

International cooperation makes the model stronger, but it can partly work without it. Physical assets can't move, and registered shares can be traced. The OECD's 2021 global minimum corporate tax shows meaningful international tax cooperation is possible even in a divided world. FATCA and the Common Reporting Standard already provide the automatic information sharing the coordination regime would build on.

The Gaps Register records that the question of the smallest workable coalition of countries is still unresolved. What can be said is that the model doesn't need everyone to take part to be worth doing. Closing some of the offshore routes still captures most UK wealth, which is held in forms that can't leave the country or have no reason to.

5.3 The Exit Tax: Settling Up When Someone Leaves

Citizenship-based taxation closes one route, but not the one wealthy UK residents use most. Giving up British citizenship is rare and legally drastic. Changing tax residence while keeping the passport is neither, and Wealth Tax or Inheritance Tax? already identifies it as the main avoidance route under the current system: a real change of residence, kept up for years and checked at death. A design that only triggers on giving up citizenship leaves that route open. It needs to trigger on the same event that other countries already target: ceasing to be UK tax resident.

This project didn't invent the mechanism. The Tax Avoidance pillar already proposes it in full, based on the US model below, at the same 95% rate as the inheritance tax. What follows extends that proposal on one point, the trigger. Three comparable countries already have deemed-disposal exit taxes, and the UK Treasury seriously considered one for the November 2025 Budget. Of those four, three trigger on residence rather than citizenship.

• United States: under IRC section 877A, a "covered expatriate" (broadly, someone with worldwide net worth above $2 million or income above a set threshold) is treated as having sold their entire portfolio at market value the day before expatriating, with gains above a lifetime exclusion ($910,000 for 2026) taxed at normal capital gains rates.³⁰
• France: Article 167 bis of the Code général des impôts triggers on a change of tax residence, not citizenship, for anyone who was French tax resident for at least 6 of the previous 10 years and holds securities worth €800,000 or more. Departing residents are treated as having sold those holdings on the day they leave. Payment is automatically deferred for moves within the EU/EEA, with full relief after 2 to 5 years depending on value, though French lawmakers moved in late 2025 to extend that period back towards its original 15 years.³¹
• Norway: tightened its exit tax significantly in 2022, closing a loophole that let the liability lapse if assets stayed unsold five years after departure. Since then, unrealised gains above NOK 3 million are taxed at 37.8% on departure, deferral is capped at 12 years, and the charge is linked to dividends, to stop people draining a company before they leave so the taxable gain shrinks.³²
• The United Kingdom: HM Treasury seriously considered a 20% "settling-up charge" on unrealised gains in UK business assets, triggered by ceasing UK tax residence, for the November 2025 Budget. It was reportedly expected to raise about £2 billion a year, with deferred payment under discussion for illiquid holdings. It wasn't adopted, but reaching Budget consideration shows this is a mechanism the Treasury has already worked through in detail, not a fringe idea.³³

The proposed mechanism, set out in full in the Tax Avoidance pillar, is a deemed disposal of worldwide assets at the moment someone stops being UK tax resident, valued using the system in Section 4.3 and taxed at 95%. Because that matches the inheritance tax rate, leaving and dying are treated the same for tax purposes. That closes the one gap in a death-triggered design: someone who emigrates late in life and dies abroad without ever settling up with the society that made their fortune. The Tax Avoidance pillar also sets out two safeguards a 95% rate needs. Deferral with interest for illiquid assets means a business owner moving abroad for reasons other than tax isn't forced into a fire sale. Apportionment by years of residence means only gains built up in the UK are taxed, not wealth built elsewhere. The instalment and equity-stake arrangements in Section 4.3 apply on the same terms. A Norway-style anti-stripping rule, linking the charge to dividends taken in the run-up to leaving, closes the obvious workaround of emptying a company before departure instead of after.

5.4 Can HMRC Enforce It?

Every defence in this section depends on a tax authority able to value private companies, unpick trusts and fight well-funded advisers in court. Gap 20 in the Gaps Register asks whether HMRC could do that at a 95% rate. The current evidence gives a mixed answer.

What HMRC has now. HMRC treats about 850,000 people as wealthy: those with income over £200,000 or assets over £2 million in any of the last three years. They paid £119 billion in personal taxes in 2023-24, a quarter of the total. About 910 full-time staff work on their compliance, and a dedicated unit for people with over £10 million existed only until 2017.³⁴ HMRC opens about 4,000 inheritance tax investigations a year, recovering around £246 million in 2024-25, and the number rose to 4,940 in 2025-26.³⁵

What the evidence says about capacity. The work pays. Compliance yield from the wealthy more than doubled, from £2.2 billion in 2019-20 to £5.2 billion in 2023-24, at a cost of about £350 million, roughly £13–15 back for every £1 spent.³⁴³⁶ But the National Audit Office found three warning signs. The rise in yield since 2019-20 exceeds HMRC's own estimate of the wealthy tax gap by more than £1 billion, which suggests non-compliance among the wealthy is larger than HMRC measures. Penalties have collapsed, from 2,153 (14% of closed cases) in 2018-19 to 456 (5%) in 2023-24. And HMRC has no full strategy for the very wealthy, whom it no longer handles separately.³⁴

What a 95% rate would add. Stage One would apply to roughly 4,600 estates a year above £2 million (Revenue Architecture §8.1): about as many cases as HMRC already investigates, but every one of them worth contesting. The binding constraint would not be headcount but specialist capacity: valuers for private companies, intellectual property and art, and lawyers able to litigate against the best-resourced advisers in the country. This is this project's own reading of the evidence, not an NAO finding.

What the design requires. Before Stage One begins, the independent inheritance tax authority (§4.4) needs:

• a dedicated unit for the largest estates, restoring and expanding what existed before 2017, with its own valuation and litigation specialists
• a published target for penalties and prosecutions, so the collapse the NAO found is reversed and visible
• funding set by the authority's own published assessment of the tax gap, not by the annual spending round; at £13–15 returned per £1 spent today, the evidence suggests more capacity would pay for itself, though returns fall as the easiest cases are worked first
• the real-time publication of valuations and reliefs described in §4.4, so under-enforcement shows up quickly

What remains open is the cost. Nobody has yet estimated what an authority able to enforce 60–70%, then 95%, would need in staff and money, or how quickly specialist valuers and litigators could be recruited. Gap 20 stays open until that costing exists.

6. Why Now: The Timing Argument

This reform wasn't designed for any economy at any point in history. It was designed for the UK in the 2020s and 2030s. Three conditions make now the right time, and an urgent one.

6.1 The Income Tax Base Is Already Eroding

The case for moving the tax base from work to wealth doesn't depend on AI displacing as many jobs as projected, because the shift is already under way. Income tax receipts are still rising in cash terms, helped by frozen thresholds, but two of the three pressures described in the Tax Avoidance pillar are happening now: wealthy taxpayers reclassifying their returns as capital instead of income, and profits shifted to low-tax countries. The third, AI taking over the office-based knowledge work that pays the most income tax, is at an early stage.

So the tax base needs rebalancing either way. What's undecided is whether the replacement is designed and working before the erosion causes a crisis, or whether a crisis forces a hurried, badly designed response. There is still time for the first, but not indefinitely.

6.2 The Baby Boomer Transfer Is the Fiscal Window

Much of the UK's £10.8 trillion of household wealth is held by the baby boomer generation, born roughly between 1946 and 1964. That generation is dying now, and the transfer of its wealth is projected to peak between 2035 and 2045.¹³ Those are the years when inheritance tax receipts will be largest, and so when the income tax cut can go furthest. Bringing the reform in after the transfer is over misses the best years of revenue; bringing it in during the transfer captures the peak.

Norway is a close parallel. It decided to save its North Sea revenue during the production peak, not after it. The UK didn't. The baby boomer transfer is the UK's equivalent moment, and it won't come round again.

6.3 Democratic Institutions Are Still Intact

The conditions for evidence-based democratic reform don't last forever. History suggests lasting reform happens in particular windows: after existing arrangements have lost credibility, and before the conditions that lead to democratic backsliding have fully set in. That window is open now, but narrowing.

If nothing checks it, wealth concentration accelerated by AI creates the conditions that have historically come before democratic capture, and that trend is visible now. The Political Renewal pillar argues that fixing the political system has to come before Economic Renewal. Both arguments are as much about timing as about policy: the chance to carry out peaceful, evidence-based democratic reform exists now, and won't last indefinitely.

7. Counter-Arguments

'People are motivated to build wealth for their children, so removing that motivation collapses enterprise'

Income tax is cut, so the incentive to earn and build during one's life gets stronger. What goes is the ability to hand a permanent advantage to descendants who didn't earn it. The wish to found a dynasty drives only a minority of people who build wealth; for most, the immediate rewards of income, status and purpose matter more. Whether dynastic ambition is a major driver of wealth creation is an empirical question the Gaps Register lists as needing research. The evidence so far, from countries with higher inheritance tax rates such as Belgium, France and Japan, shows no collapse in enterprise.

'The wealthy will restructure assets and avoid the tax entirely, so this just produces an expensive compliance industry'

Property can't move. Shares are registered. Citizenship-based taxation triggers the tax on renunciation. Foundations must spend down within one generation, with no family control. Section 5 deals with each route in turn. Even so, avoidance at 95% will be extensive and well funded, which is why the constitutional protection, the independent authority and real-time disclosure are essential, not optional extras. The Tax Avoidance pillar shows how much avoidance there is at 40%, and the Gaps Register accepts that the incentive grows enormously at 95%. The design starts from that incentive instead of ignoring it. The October 2026 Budget, which left capital gains tax rates unchanged while raising tax on savings and property income, is a reminder that the same fear constrains policy at far lower rates than 95% (see Wealth Tax or Inheritance Tax?, Section 10).³⁷

'Forced liquidation of family businesses destroys jobs and productive enterprise'

Nobody would be forced to sell. The equity stake mechanism lets the state take a share of ownership instead of cash, repaid from future profits. Payment can be staged over 10–20 years for assets that really are illiquid. Primary homes and modest savings are protected below the threshold. A family business built over forty years doesn't have to be sold. The design is meant to tell productive enterprise apart from accumulated dynastic wealth, which are different things even when they sit in the same company.

'The transition financing gap is too large, imposing enormous debt on current taxpayers to benefit future generations'

Corrected 14 October 2026. This answer used to defend a £1–4 trillion transition gap. On corrected figures (§4.1) there's no transition to finance: income tax is cut only as far as proven inheritance tax revenue pays for, so the cuts follow the money instead of borrowing ahead of it, and the debt this objection describes doesn't arise. What remains of the objection is different: that a 95% rate and its anti-avoidance machinery are a lot of effort for revenue worth about a fifth of income tax and NI. The answer is that revenue is only half the case. The other half is limiting inherited advantage (§3), which a smaller income tax cut doesn't weaken.

'The state cannot be trusted with this much power over wealth'

The model changes the state's relationship with wealth instead of simply handing today's state more power. It takes private money out of politics, which is how concentrated wealth captures the state (see the Political Renewal pillar), and adds public votes on spending, an independent inheritance tax authority and real-time public disclosure. The objection applies just as much to the current arrangement, in which concentrated private wealth already has a firm grip on much of law-making and regulation. Power is already concentrated; the question is which arrangement holds it to account.

'This is double taxation: the money was already taxed as income when it was earned'

Much of it wasn't. Large estates are mostly assets that have grown in value (shares, property and private businesses), and that growth is often never taxed at all. Capital gains tax is not charged at death: the heirs are treated as acquiring the assets at their value on the date of death, so a lifetime's gain is wiped clean.³⁸ Where business or agricultural relief also applies, the same asset can pass free of both inheritance tax and capital gains tax, which is why the Office of Tax Simplification recommended in 2020 that the uplift be removed in those cases.³⁹

Where the money was taxed as income, the 95% falls on a different event and a different person. The original earner paid income tax on what they earned. The heir receives a sum they didn't earn, and pays no income tax on it, because an inheritance isn't income to the person who receives it. What is taxed is the transfer, once, when it happens.

Taxing the same money more than once is also normal. Wages are taxed as income, then again through VAT when they are spent, stamp duty when they buy a house and council tax every year after. Double taxation in the stricter sense, the same profit taxed twice in the same owner's hands (corporation tax and then dividend tax), is a different thing, and the tax system already softens it through lower dividend rates.

The objection still has force for one kind of estate: savings built up from salary that was taxed in full, passed to children. For that case the answer isn't arithmetic but the value judgement in §3, that inherited advantage shouldn't compound across generations. The threshold also matters: Stage One applies only above £2 million, and primary homes and modest savings are protected below the threshold.

'This has never been tried at 95% and never worked'

Sweden had an inheritance tax, with a 70% top rate from the late 1950s, until 2004: a real precedent, though well short of the 95% proposed here. It wasn't abolished because it wrecked the economy. It was abolished because its institutions couldn't stop it being hollowed out. Valuation reliefs for family firms had already eroded it from the 1970s, a parliamentary majority cut the top rate to 30% in 1992, and spousal bequests were exempted in 2003 before full abolition. The lesson is that the policy can work, but the institutional design must prevent that kind of erosion. The UK today is also a different setting: digital organising has narrowed the gap between scattered public interest and well-funded private lobbying. A movement that can publish avoidance data as it happens changes the politics of implementation in a way that wasn't possible in Sweden in the 1980s.

9. Proposals for Change

The proposals below are the core of this pillar, put forward for public examination and challenge. They are ordered by stage: what has to happen first, what follows, and where it ends up.

Stage One: Immediate (Years 1–5)

• P3 Introduce a 60–70% inheritance tax on all estates above £2 million, with real avoidance closure: no Business Property Relief for non-trading assets, no AIM exemptions and no offshore trust shelters. This first stage builds the administrative systems, produces real revenue data and earns public acceptance before the full rate applies.

• P4 Set up an independent inheritance tax authority, governed at arm's length from government, with a board appointed through a citizens' assembly. It has sole responsibility for valuation, enforcement and the administration of reliefs, and publishes all assessments, reliefs claimed and effective rates in real time.

• P4 Begin the constitutional protection process: set the inheritance tax rate in a document that needs a supermajority to amend. The rate set in Stage One is the one the protection must defend, and this can't be done once the coalition that won the reform has broken up.

• Publish a Transition Financing Plan: an OBR-style document setting out the revenue path under Stage One, the projected revenue at the baby boomer peak, and the schedule for cutting income tax in step with revenue. This is the document that makes Stage Two believable.

Stage Two: The Shift (Years 5–20)

• P3 Move from 60–70% to 95% on estates above the threshold once the institutions (valuation capacity, HMRC enforcement and the independent authority) are shown to be working, judged by the five tests in §4.5. The move to the full rate follows the evidence, not a political timetable.

• Begin cutting income tax, starting with the lower rates, in step with proven growth in inheritance tax revenue. The cut isn't a giveaway; it moves part of the tax base from work to wealth. Each percentage point off income tax is matched by proven inheritance tax revenue that replaces it.

• Capitalise the UK Sovereign Wealth Fund from a set share of inheritance tax receipts. The money isn't available for day-to-day spending, and withdrawing the principal needs cross-party support in Parliament. The fund embodies the principle that the transfer of wealth between generations should leave a permanent endowment, not just fund current spending.

• Launch Lifetime Legacy Credits and Directed Investment Vehicles, the spend-down mechanisms that work with human psychology. Lasting recognition replaces income tax relief as the way to steer wealthy people's spending towards socially useful ends.

Long-Term Architecture (Years 20+)

• Income tax permanently lower, by as much as mature inheritance tax revenue pays for: on corrected figures, up to about a fifth of today's income tax and NI at the theoretical ceiling, and less in practice. Full abolition isn't the goal, because not enough wealth passes between generations to replace income tax (§4.1). The UK tax system is rebalanced, with far more of the burden falling on accumulated wealth when it passes between generations and less on work.

• The Sovereign Wealth Fund is up and running and growing. Its returns start to reduce the UK's dependence on any single tax. The public finances become sturdier, more broadly based and more realistic about where the UK's wealth actually sits.

10. The Kill Sheet: Conditions Under Which This Proposal Would Not Proceed

This section collects existing material; it adds nothing new. S5_05_ScientificMethod.md sets out the format for falsification tests (Prediction / Magnitude / Time horizon / Counterfactual / Falsification condition), and several pillars use it. Until now there was no single place listing the tests that bear on whether this proposal should go ahead, so readers had to find them across the pillars it draws on. Each row below restates an existing falsification condition in close to its original words and links to the full test.

Any one of these failing wouldn't necessarily kill the whole proposal. Each concerns one part of the design (how durable the rate is, how well avoidance is closed, or whether this was the right instrument), not whether the proposal should exist. All three failing together is the closest thing this project has to a clear signal to stop, and even that isn't formally modelled as an interaction. Gap 25 in the Gaps Register calls for exactly that kind of cross-pillar model; this table only gathers what already exists.

How to Read This Pillar

This pillar is the prescription. S3_01 (How Tax Works) is the foundation: what tax is, how it works, and why the low-tax countries often held up as models aren't what they seem. S3_02 (Tax Avoidance) is the diagnosis: how the current system fails, whom it fails, and why gradual reform can't fix a system exploited at every margin. This document is where the diagnosis leads.

Each of the three stands on its own. Together they make a complete argument: foundation, diagnosis, prescription. The Gaps Register lists the known weaknesses of the prescription, and the forums exist so those weaknesses can be challenged, refined and, where there's better evidence, corrected.

Readers are invited to challenge any of it. In this project, documents change on evidence, not assertion. Bring evidence and the argument changes; an assertion is noted but changes nothing.
