Wealth Tax or Inheritance Tax?

THE GENERATIONAL RESET

This document is a companion to the Economic Renewal pillar (S3_04) and the Revenue Architecture (S3_05). It deals with the challenge most often raised against the project's core tax proposal: that an annual wealth tax above a high threshold is a more practical, achievable and economically sound alternative to a high inheritance tax at death. The Generational Reset takes that challenge seriously, and this document gives it the full analysis it deserves.

Key Proposals

1. The Question

The Economic Renewal pillar proposes a 95% inheritance tax on all wealth at death, paying for a substantial income tax cut. The most serious alternative is an annual wealth tax: a recurring charge on net wealth above a threshold, typically 1–2% on wealth above £10–20 million.

These are not two versions of the same idea. They are different interventions, with different revenue, different effects on behaviour, different administrative demands and different politics. Choosing between them is not a question of degree but of what you are trying to achieve and which tool actually achieves it.

This document sets out both cases, compares them head to head on each key dimension, and explains where the Generational Reset lands and why. The conclusion is that a high inheritance tax is the right instrument, but the case for the wealth tax is strong enough to need a full answer, not a dismissal.

2. What Each Proposal Looks Like

The Annual Wealth Tax (2% above £20m)

An annual wealth tax charges a percentage of net wealth above a threshold every year. The UK Wealth Tax Commission (2020)¹, an independent academic body set up to study the question, recommended against an annual wealth tax and instead proposed a one-off charge of 5% on individual wealth above £500,000, paid over five years at 1% a year, as the most workable version for the UK. A recurring annual tax on high wealth is a different and more ambitious tool.

In the design most often proposed, the charge is 2% a year on net wealth above £20 million. The threshold is deliberately high: Tax Justice UK estimates that around 20,000 people have wealth above £10 million, so fewer than that would be above £20 million.² The 2% rate is meant to be defensible as a modest contribution rather than confiscation.

At £50 million of net wealth, the annual charge is 2% of £30 million: £600,000 a year.

At £500 million, it is 2% of £480 million: £9.6 million a year.

Over 30 years of building wealth, a 2% annual tax takes a significant fraction of the total, but the wealth still exists, still compounds and can still be inherited.

The High Inheritance Tax (95% at death)

The Economic Renewal pillar proposes a 95% tax on all wealth at death, applying to everyone, with no exemptions by type of asset and no threshold below which wealth escapes. It is paired with a substantial income tax cut, paid for by the inheritance tax revenue. It was originally designed to replace income tax entirely; corrected figures for wealth transfers (§4.1) show it can pay for about a fifth at most.

At £50 million, the tax at death is 95% of £50 million: £47.5 million, collected at a single point.

At £500 million, it is 95% of £500 million: £475 million, again at a single point.

The proposal openly acknowledges the problem of lifetime gifts: if the death rate is 95% but gifts are taxed less, people will rationally give their wealth away before they die. So the design requires a unified tax on lifetime gifts and estates, with every transfer, whenever it is made, counted against the same 95% threshold.

3. The Steel Man for the Annual Wealth Tax

The case for an annual wealth tax is serious and deserves proper engagement.

Taking the arguments one at a time:

Revenue now, not later. The inheritance tax waits. A 70-year-old with £200 million may live another 20 years, during which their wealth keeps compounding, their estate planners keep working, and the revenue is zero. The annual wealth tax collects every year.

Political achievability. A 2% charge on wealth above £20 million is a modest request that polls well and is harder to caricature as confiscation. A 95% death tax is easier to attack as punitive, and political attacks on tax proposals have historically worked better than the numbers justify.

Avoidance is harder than it looks. The standard objection to wealth taxes, capital flight as seen in France, is real but overstated. France's wealth tax had a low threshold that caught middle-class property owners who had nowhere to go. A tax aimed only at wealth above £20 million applies to people who could leave, but they have professional ties, families and reputations that make leaving costly in ways the simple capital-flight model ignores.

It doesn't need a death. An inheritance tax cannot touch the wealth of a 90-year-old who has spent 70 years arranging their estate. An annual wealth tax applies regardless of age or whether any transfer has been made.

Valuation is manageable at the top. Annual valuation is complicated, but at a £20 million threshold it applies to few enough people that individual annual assessment is feasible, especially for listed shares, which make up most wealth at this level.

4. The Case for the High Inheritance Tax

4.1 The Revenue Gap Is Decisive

The first test for any tax proposal is whether it raises enough to be worth its administrative and political costs. On this test the two proposals are not close.

A 2% annual wealth tax above £20 million would raise something like £8–15 billion a year. That is this project's working estimate; no published costing of this exact design was found. The nearest, Tax Justice UK's campaign estimate for 2% on wealth above £10 million, is £24 billion a year, which others treat as an upper bound, and a £20 million threshold would raise less.² That is a meaningful sum, but nothing like the £475 billion income tax and National Insurance raise. It adds to the existing tax base rather than replacing any part of it, so income tax continues with all its disincentives to work and its exposure to AI intact.

A 95% inheritance tax, with full capture of lifetime gifts, applies to transfers between generations currently running at roughly £100–115 billion a year and projected to double or more by the 2040s in cash terms. Its theoretical yield is roughly £95–110bn a year at today's values, a ceiling that assumes 95% of every pound transferred, with no threshold, exemptions, avoidance or spending down. Corrected 14 October 2026: this section previously used transfers of £250–400bn rising to £350–450bn and a yield of £200–400bn at peak, and concluded the inheritance tax could replace income tax. No source supports those transfer figures. Neither instrument can replace income tax.

That arithmetic is the heart of the matter. The inheritance tax still raises several times what the wealth tax would, around £95–110bn at its ceiling against £8–15bn, so if the aim is to move a meaningful share of the tax base from earnings to wealth, it remains the stronger tool. But it can pay for a cut in income tax, not replace it.

4.2 Leaving Is Harder to Use Against a Tax at Death

The strongest practical argument for the inheritance tax over an annual wealth tax is about leaving the country.

To avoid an annual wealth tax, you leave. Under France's wealth tax, many wealthy people quietly moved to Belgium, Switzerland or the UK before the tax was scrapped. Sweden abolished its wealth tax. Spain's applies unevenly across regions. The international evidence is that annual wealth taxes above a certain rate produce capital flight that erodes the base faster than rate rises add to it.

To avoid UK inheritance tax you also have to leave, but the bar is higher. Since April 2025, UK inheritance tax on worldwide assets depends on long-term residence: anyone resident in the UK for at least 10 of the previous 20 years is within its scope, and stays within it for between 3 and 10 years after leaving, depending on how long they lived here (10 years for those resident 20 years or more). So escaping it means leaving and staying away for years, giving up the professional, social and family life built here. HMRC can and does challenge claims that someone has left when they have not. Death is the final verification point: where did the person actually live, where were their children educated, where did they get medical treatment? Leaving is possible, but it is costly, visible and needs a real change of life, not just an administrative restructuring. The Economic Renewal and Tax Avoidance pillars propose an exit tax on top, so that leaving settles the bill rather than escaping it.

On this measure the inheritance tax is harder to avoid than an annual wealth tax.

4.3 Valuing Once, Not Every Year

Valuing complex wealth every year is a formidable administrative task. A business empire made up of private companies in several sectors, residential and commercial property, art, farmland, offshore trusts and pension arrangements would have to be valued every year. Valuing private companies is inherently subjective: reasonable people disagree about discount rates, comparable companies and how to treat minority stakes. Taxpayers and their advisers will fight valuations hard, because at 2% a year, knocking £10 million off a valuation saves £200,000 every year indefinitely.

An inheritance tax values at one defined point. The estate has time to prepare, and HMRC applies established principles that, though imperfect, have decades of case law behind them. Disputes happen, but they happen once.

For private businesses, the most complex and contested valuation question, the difference matters. Valuing a growing private company every year creates uncertainty that the owner, the board and the lenders must manage every year. Valuation at death, with payment terms that let the business carry on while paying the tax over time, disrupts it once. The instalment option (below) largely solves the business succession problem that an annual wealth tax creates through constant uncertainty.

4.4 The Incentives Work with Human Nature

The Economic Renewal pillar makes a specific argument about behaviour that is often missed: at 95%, spending down is the rational response. The wealth exists for the person who built it. They can spend it, invest it in their business, give it to charity, back ventures they believe in, or pay their children's school fees. What they cannot do is keep it intact for their descendants to inherit tax-free.

That is the intention, not a flaw. Money put to use by its owner (spent, invested, donated, circulating in the economy) is better for everyone than money held in trust for unborn grandchildren, and the 95% rate maximises the incentive to put wealth to use during life.

An annual wealth tax creates a different incentive: keep the valuation down. Private companies are restructured to look less valuable, and property is held in entities that attract discounts. Effort that should go into using wealth goes into suppressing its measured value for tax purposes.

4.5 The Dynastic Wealth Argument

There is a difference of principle between the two instruments that the revenue figures and avoidance mechanics should not hide.

A wealth tax taxes successful living people on the wealth they have built. A founder who has built a £50 million company, employing 200 people, exporting and contributing to the economy, pays 2% of their net wealth every year. The tax does not distinguish between wealth earned and wealth inherited, or between wealth being put to work and wealth sitting in offshore structures. It charges the entrepreneur who built a fortune the same rate as the heir who received one.

An inheritance tax taxes the transfer of wealth between generations. The living person pays nothing on what they have accumulated, so the incentive to build is fully kept. What the tax removes is the ability to pass accumulated advantage intact to heirs who did not build it. The Monopoly board resets between generations; the game carries on within each lifetime.

This matters because the Economic Renewal pillar's core argument is about dynasties, not wealth as such. The objection is not to people building large fortunes. It is to those fortunes becoming permanent advantages handed down the generations, an aristocracy by another name. The inheritance tax addresses that objection directly. The wealth tax addresses a different question.

5. The Empirical Record

France (wealth tax 1982–86, then ISF 1989–2017)

France's wealth tax is the most cited evidence in this debate, usually by its critics. The ISF was abolished by Emmanuel Macron in 2017 and replaced by a tax on property wealth only (IFI). The standard account is that it drove capital flight, reduced investment, raised less than expected and eventually became politically untenable.

The full picture is more complicated. For much of its life the ISF started at €800,000 of net wealth, rising to €1.3 million from 2012.³ That caught not only the very wealthy but upper-middle-class owners whose main asset was their home and who had no practical way to reduce their bill. This design flaw made it politically toxic in a way a high-threshold version would not have been. The capital flight it caused was real but concentrated in mobile financial assets, not the wealth tied up in founders' businesses. Its abolition was a political choice as much as an economic one: Macron's IFI still raises revenue, just on a narrower base.

The lesson is not that wealth taxes cannot work. It is that a low threshold creates a large pool of mildly aggrieved taxpayers and an easy political coalition against the tax.

Norway (formuesskatt)

Norway has had an annual wealth tax since the 19th century, currently around 1% on net wealth above roughly £125,000, with a higher rate of 1.1% on very large fortunes. It raises about 0.4% of GDP.⁴ It has not been abolished.

Norway has seen real capital flight linked to a specific policy change. In 2022 it raised the top wealth tax rate to 1.1% and tightened its exit tax rules for people who emigrate, and wealthy departures roughly doubled in the following two years compared with before 2022: according to the think tank Civita, 261 residents with assets above 10 million kroner left in 2022 and 254 in 2023.⁵ That is a real, measurable response to a specific rate rise, not a rounding error. But the wealth tax has not been abolished or reversed; the government judged the trade-off worth making rather than treating the departures as a reason to retreat.

Norway shows that a modest annual wealth tax with a workable threshold can last. It does not show that one can raise anything like the revenue of income tax.

Sweden (abolished 2007) and Germany (suspended 1997)

Both countries had annual wealth taxes that were suspended or abolished: Sweden because of capital flight and administrative complexity, Germany because its constitutional court ruled that the way assets were valued discriminated between them.⁶ Neither decision was mainly economic; both reflected political and constitutional circumstances specific to those countries.

United States (estate tax)

The US unified gift and estate tax, which applies at death and counts gifts made during life against the same lifetime exemption, is the closest existing model to what the Economic Renewal pillar proposes. In 2001 the top rate was 55%, applying to estates above $3 million. It has since been weakened repeatedly, by tax cuts in 2001, 2017 and 2025. The top rate is now 40%, with a $15 million exemption per person from 2026.⁷

The US experience shows that a unified gift and estate tax can be run. It also shows how vulnerable estate taxes are to sustained political attack: polling on the "death tax" is consistently negative. The lesson for a high inheritance tax is not that the mechanics fail, but that lasting political support needs a level of public understanding that opponents will work hard to prevent.

6. Head to Head

7. The Key Tension: Avoidance at 95%

The most serious objection to a 95% inheritance tax is not that it is wrong in principle but that it is too high in practice. At 95%, every pound passed to an heir costs 95p in tax, so the incentive to give during life, use trusts, make charitable donations that keep family influence, or set up offshore family offices is at its maximum. The avoidance industry will have decades to work.

This is a real concern, and the Generational Reset takes it seriously.

The design response has three parts.

P2 First, a unified lifetime transfer tax. Every gift, trust transfer or other transfer of wealth during life counts against the same 95% threshold as the estate at death. This mirrors the US unified gift and estate tax, which has worked, imperfectly but functionally, for decades. Transferring wealth before death then does not reduce the tax; it just brings collection forward.

P3 Second, instalment payments for business assets. Forcing the immediate sale of a productive private business to pay a 95% inheritance tax would be economically destructive and politically indefensible. The answer, again based on existing US estate tax rules, is to let tax on business assets that keep operating be paid in instalments over 10–15 years. The tax is still owed, but the business pays it from its cash flow instead of being sold. This answers the most emotive objection (the family farm, the family business) without the blanket business exemption that cost £1.3 billion a year through Business Property Relief before the 2026 reforms capped it.

P4 Third, anti-avoidance design. Today's 40% IHT falls to an effective 12% for the largest estates partly because the rate is high enough to motivate avoidance but not high enough to make closing the loopholes worth the political fight. At 95%, every avoidance route is worth closing, because the revenue at stake on each is large enough to justify the legislative effort. This is counterintuitive, but the logic is that a higher rate raises the stakes for government as well as for taxpayers, and so strengthens the case for closing loopholes.

8. Where the Generational Reset Lands, and Why

The Generational Reset proposes a 95% inheritance tax, not a 2% annual wealth tax, for five reasons.

Revenue. A 2% wealth tax above £20 million raises £8–15 billion a year. It does not replace income tax or pay for a substantial cut, and it does not solve the fiscal problem. It is a useful addition to an unreformed system, not an alternative to reform. Only the inheritance tax model raises enough to pay for a substantial income tax cut.

Avoidance resistance. You cannot avoid dying. You can move abroad to escape an annual wealth tax, and the international evidence suggests that above a certain threshold a meaningful number of wealthy people will. Escaping the inheritance tax means leaving and staying away for years, the final reckoning comes at the point hardest to fake, and the proposed exit tax closes the route altogether.

Administration. Valuing complex private wealth every year means continuous disputes, continuous uncertainty and a large ongoing compliance industry. A single valuation at death, with instalments for business assets, is simpler to run and more legally settled.

Precise targeting. The problem the Economic Renewal pillar addresses is dynasties: advantage handed down through the generations, creating an aristocracy by another name. The inheritance tax targets exactly that. The wealth tax charges successful living people every year on wealth they are using. They are different tools for different problems.

The incentive to spend down. At 95%, the rational response is to spend and invest during your life: in your business, in consumption, in charity, in ventures you believe in. That is economically productive. An annual wealth tax encourages suppressing valuations, which is not.

The Generational Reset does not argue that a 2% annual wealth tax is wrong or has no place. Within a broader portfolio, alongside the inheritance tax and the corporation tax and carbon pricing reforms in the Revenue Architecture pillar, a modest annual levy on very large fortunes may have a role. But it is not the main instrument. That role belongs to the inheritance tax.

8.1 The Argument, Made Explicit

Sections 1 to 8 make the case for the inheritance tax over the wealth tax in ordinary prose. This section restates the same case in a structured form, following How We Reach Conclusions, to show the working rather than ask readers to take it on trust. Nothing here is new; each stage restates what the sections above establish, with its confidence labelled.

9. What This Does Not Resolve

Several things remain uncertain.

A 95% rate may produce more avoidance than the modelling suggests. Forty years of creative structuring, offshore trust law and philanthropic vehicles eroded a 40% IHT to as little as 12% effective for the largest estates. The step from 40% to 95% is enormous, and the assumption that a unified lifetime gift tax and instalment payments solve the avoidance problem may be optimistic. The Gaps Register records this.

Revenue timing is a real problem. The inheritance tax collects at death, while the income tax it is meant to cut is collected every year. So the cut has to follow the revenue: Economic Renewal makes no income tax cut in its first stage, and only cuts income tax as inheritance tax receipts are proven. The Revenue Architecture pillar sets out the sequencing, but this remains the hardest practical part of the proposal.

Business succession is disruptive even with instalments. A private business paying off a 95% inheritance tax over 15 years is committing a large share of its operating cash to tax. For capital-intensive businesses with thin margins, that may be a real constraint that instalments do not fully solve.

The politics are extremely hard. The wealth tax, because it is modest, is more politically survivable. A 95% inheritance tax needs a political coalition strong enough to pass it against people with very large resources and very strong reasons to stop it. The Political Renewal pillar's argument, that political reform has to come before economic reform on this scale, is not a side issue for this proposal. It is essential to it.

10. Counter-Arguments

'Why compare only a wealth tax and an inheritance tax? A land value tax or reformed capital gains tax could raise similar revenue with fewer of either option's problems'

This document exists to give the wealth tax challenge, the alternative most often raised against this project's core proposal, the full treatment it deserves, not to survey every possible tax at once. Land value tax, corporation tax reform and carbon pricing are covered as part of the same portfolio in the companion Revenue Architecture document, not excluded. The question here is narrower: of the two instruments most often proposed as alternatives for taxing accumulated wealth, which can move the larger share of the tax base off income? Neither can replace it entirely. That is a different question from "what is the single best tax", and answering it does not mean ruling out every other instrument.

'A 95% rate is a statement of values, not a way of maximising revenue. A more moderate rate would raise nearly as much with far less distortion and political resistance'

The numbers don't support "nearly as much". The whole case for the inheritance tax over the wealth tax is that it is the only instrument that can pay for a substantial income tax cut; the wealth tax, at £8–15bn a year, cannot. A meaningfully lower inheritance tax rate would not just cut revenue in proportion. Under the rules before April 2026, the 40% headline rate fell to roughly 12% for large estates once reliefs applied, and a rate high enough to make avoidance not worth the fight is designed to close exactly that gap. A moderate rate leaves the avoidance industry's incentives roughly where they are. It would raise more than today's system, but nowhere near enough to do the job this pillar gives it.

The October 2026 Budget is a small, real test of the political side of this objection, and it does not help this pillar. Even a moderate rise in a tax on wealth was not made: the main rates were left unchanged, and the government raised income tax on savings and property income instead.⁹ The Budget gave no reason, so it shows what was decided rather than why. But it is consistent with the view that concern about wealthy people leaving or waiting to sell constrains taxes on wealth even at moderate rates. That is a harder problem for a 95% rate, not an easier one, and this pillar's case depends on the avoidance and residence safeguards in Section 5 being strong enough to answer it.

'People who spend down or give away their wealth gradually over decades will pay proportionally less than someone who dies suddenly with their estate intact. The tax penalises bad timing, not wealth'

This is exactly what the unified lifetime transfer tax is designed to prevent. Under this proposal every gift, trust transfer or lifetime transfer counts against the same 95% threshold as the estate at death: giving early doesn't reduce the tax, it only brings forward when it is collected. Real, arm's-length charitable giving is treated differently, on the view that money leaving a family's control entirely for public benefit is a different act from wealth quietly passed to the next generation of the same family. Ordinary lifetime gifts to heirs get no exemption for having been made early.

11. Proposals for Change

These are the evidence-based proposals of this document, put forward for public discussion and challenge.

• Choose a 95% inheritance tax over a 2% annual wealth tax as the main instrument. A wealth tax raises £8–15bn a year; the inheritance tax model's ceiling is several times that, at roughly £95–110bn. Neither replaces income tax, but only the inheritance tax can pay for a substantial cut.

• Introduce a unified lifetime transfer tax. Every gift, trust transfer or lifetime transfer counts against the same 95% threshold as the estate at death, so giving early doesn't reduce the tax; it just brings collection forward.

• Allow instalment payments for business assets. Tax owed on a private business is paid from cash flow over 10–15 years instead of forcing an immediate sale, answering the family-business objection without a blanket exemption.

• Treat a 95% rate as the reason to close avoidance routes, not a reason to fear them. A rate this high makes every loophole worth the legislative effort to close, unlike the 40% IHT, which Business Property Relief alone cut to 12% for estates over £30 million before the April 2026 reforms.
