The whole question, in five minutes

From April 2026, if you die holding more than £2.5 million of shares in a private UK trading company, your family pays inheritance tax on the part above that — at an effective rate of 20 per cent, paid in instalments over ten years, interest-free. Before, they paid nothing.

The change affects up to about 1,100 estates a year across the whole country. Up to 185 of these include an agricultural property relief claim (farms or part-farm estates). The other 915 or so are business-property-relief-only estates — family businesses, founder equity in unlisted companies, AIM-listed shareholdings, and similar holdings.

Why it matters even if you are not affected

It is not really about the money. The measure is forecast to raise about £140 million in 2026-27, rising to roughly £300 million a year in later forecast years — small in government terms either way. It is about whether the people who could build the next generation of UK companies stay here or leave.

If they stay, those companies create jobs and pay corporation tax for decades. If they leave, the money goes elsewhere. The country has been saying for years it wants more big UK technology companies. Whether this tax change makes that harder is the actual question.

The argument is not about how much. It is about when.

This publication accepts the principle of taxing very large private business holdings when they pass between generations. Cash gets taxed. Shares listed on the stock market get taxed. Property gets taxed. Private trading-company shares used to get a permanent free pass. The change ends that. The principle of the reform is broadly accepted; the public debate around it is mostly about timing and mechanism, not whether the principle is right.

What is contested is when the tax should fall.

The government has chosen to tax at death. The estate is valued and the bill is calculated based on what the shares are worth on the day someone dies. The shares may be worth £15 million on paper but cannot be sold. The family owes the tax anyway.

The other answer — Australia uses it, several UK practitioners argue for it — is to tax at realisation. The heir inherits the shares. The bill arrives when the shares actually turn into money: when the company is sold, or goes public, or someone buys them out.

Same principle. Same broad rate. Different mechanics. One creates liquidity problems and pre-emptive relocation pressure. The other does not.

What the publication thinks

The principle is right. Letting very large private business holdings pass entirely tax-free, while every other kind of wealth gets taxed, was not fair. Concentrated inherited wealth also has measurable effects on social mobility and on heir productivity that argue for taxing it. The publication is willing to say this directly.

The mechanism is contested. Charging the tax at death on shares that cannot be sold creates real problems for one specific kind of business — the high-growth UK tech companies the country says it wants more of. Whether those problems outweigh the fairness benefit is something the government has not yet shown its working on.

The right next step is for HMRC and the Office for Budget Responsibility to publish the modelling they have done. They should consult on whether different mechanisms might work better for different kinds of business — farms, mature family companies, AIM-listed shares, high-growth founder equity are not the same thing. They should review what actually happens after three years.

The shortest possible version

The principle is right. The amount is roughly right. The timing — death versus realisation — is the part the government has not justified. The way to settle it is evidence, not rhetoric.

Both the pro-reform and anti-reform slogans are wrong. The actual question is much smaller and more answerable than either side has been making it sound.
