John Healey Inheritance Tax AI Proposal: 10-Year Gifting Rule Could Affect UK Families

Chancellor John Healey is facing fresh debate over Britain’s inheritance tax system after three leading artificial intelligence platforms recommended extending the seven-year gifting rule to 10 years and introducing a £500,000 lifetime allowance for tax-free gifts.

The recommendations emerged after The Telegraph asked ChatGPT, Google’s Gemini and Anthropic’s Claude to identify potential tax reforms ahead of Healey’s first Budget on 28 October 2026.

All three systems identified inheritance tax as an area for reform, with suggestions focusing on restricting opportunities for wealthy individuals to transfer assets without paying inheritance tax.

Gemini proposed extending the gifting period and introducing a lifetime allowance of £500,000, estimating that the changes could generate an additional £200 million to £400 million annually.

However, these are AI-generated recommendations, not confirmed government proposals. Healey has not announced plans to adopt the suggested changes.

The discussion comes as families are already preparing for significant inheritance tax reforms affecting pensions, agricultural assets and family-owned businesses.

Why Has AI Recommended Changes to the Seven-Year Inheritance Tax Rule?

Under current UK inheritance tax rules, individuals can transfer money, property or other assets to family members without an immediate inheritance tax charge in many circumstances.

Qualifying gifts generally become exempt from inheritance tax if the donor survives for at least seven years after making them.

If the donor dies within that period, the gifts may be included when calculating inheritance tax liabilities.

Gemini suggested extending this period to 10 years, arguing that the existing arrangements create opportunities for wealthier households to reduce their taxable estates through lifetime transfers.

Claude also recommended considering a longer gifting window, potentially accompanied by revised taper relief.

ChatGPT suggested retaining the current 40% inheritance tax rate while examining ways to reduce avoidance opportunities and simplify the system.

The difference between existing legislation and the suggested reforms is significant.

The proposals would potentially make it more difficult for individuals to transfer substantial wealth outside their taxable estates.

Families considering large financial transfers often examine the rules for declaring cash gifts to HMRC when planning how to support children or grandchildren.

However, extending the gifting period would not automatically make every gift taxable.

The eventual liability would continue to depend on the donor’s estate, applicable exemptions and the precise structure of any legislation.

Could a 10-Year Gifting Rule Increase Inheritance Tax Bills?

One important consequence of the AI recommendation concerns gifts made eight or nine years before death.

Under existing rules, a qualifying outright gift generally falls outside inheritance tax after seven years.

A hypothetical 10-year rule could extend the period during which that transfer remains relevant.

Consider a parent who gives £300,000 to an adult child to help purchase a property.

If the parent dies nine years later, that qualifying gift would ordinarily fall outside the existing seven-year rule.

Under a hypothetical 10-year system, the same gift could still affect the inheritance tax calculation.

This would be particularly important for families whose estates already exceed the available tax-free thresholds.

However, the government would need to determine whether the proposed changes applied to gifts already made or only to future transfers.

There is no confirmed proposal to apply a longer gifting period retrospectively.

The wider economic argument is not new.

Arun Advani and David Sturrock, economists whose research was published by the Institute for Fiscal Studies in September 2023, examined weaknesses in inheritance tax treatment of lifetime gifts.

Their analysis identified how individuals able to make substantial gifts sufficiently early can reduce inheritance tax exposure, creating advantages for families with considerable transferable wealth.

They also questioned the design of existing taper relief, which reduces tax on certain gifts made between three and seven years before death.

Their research highlighted an important problem: the current system can create a sharp difference in tax liability depending on whether the donor survives just under or just over seven years.

While their analysis supports examining how lifetime gifts are taxed, it does not endorse the specific AI-generated 10-year recommendation.

A longer gifting period could also create practical difficulties for executors required to identify historical transactions.

Would a £500,000 Lifetime Gifting Allowance Affect Middle-Income Families?

The proposed £500,000 lifetime gifting allowance raises additional questions.

Currently, there is no general lifetime limit on the value of potentially exempt transfers an individual can make.

For example, a parent can give £200,000 to each of three children.

If the parent survives seven years after each qualifying transfer, the combined £600,000 could ordinarily fall outside inheritance tax.

Under a hypothetical £500,000 lifetime allowance, £100,000 would exceed the suggested limit.

However, the AI proposal does not explain how that excess would be taxed or how existing exemptions would interact with the new allowance.

Several important questions remain unresolved:

• Previous gifts: Would transfers made before implementation count towards the £500,000 limit?
• Married couples: Would each spouse receive a separate lifetime allowance?
• Existing exemptions: Would the £3,000 annual exemption remain available?
• Regular family support: Would qualifying gifts made from surplus income remain exempt?
• Business transfers: Would gifts involving company shares or agricultural property receive special treatment?

These details would determine whether the proposal primarily affected wealthy households or created wider financial-planning difficulties.

A £500,000 lifetime gifting allowance should also not be confused with the existing potential £500,000 inheritance tax threshold available to some individuals when the residence nil-rate band applies.

They concern different parts of the inheritance tax system.

Why Is John Healey Facing Pressure to Reform Inheritance Tax?

The AI experiment comes ahead of a Budget expected to address substantial pressure on Britain’s public finances.

The Institute for Fiscal Studies has highlighted approximately £35 billion in spending pressures, adding to concerns about the sustainability of existing fiscal plans.

Healey must balance demands for public spending with the government’s commitments to fiscal discipline.

Inheritance tax reform could theoretically generate additional revenue without increasing the headline 40% rate.

However, Gemini’s estimate of £200 million to £400 million in additional annual receipts has not been independently validated by HM Treasury or the Office for Budget Responsibility.

Actual revenues would depend on the legislation, taxpayer behaviour and the effectiveness of enforcement.

Another complication is that inheritance tax reforms are already being implemented.

From 6 April 2027, most unused pension funds and pension death benefits will be brought within inheritance tax.

These changes are already legislated and should not be confused with the AI suggestions.

The pension inheritance tax changes scheduled for April 2027 could increase liabilities for some estates containing substantial retirement savings.

Agricultural Property Relief and Business Property Relief have also changed.

Since April 2026, the combined value of qualifying agricultural and business assets eligible for 100% relief has generally been limited to £2.5 million per individual.

Qualifying assets above that allowance can receive 50% relief, subject to the relevant conditions.

For some family businesses, additional restrictions on lifetime gifting could complicate succession planning.

The distinction between confirmed tax reforms and AI-generated suggestions is therefore particularly important.

Could Families With £1 Million Estates Be Affected?

Under existing inheritance tax rules, the standard nil-rate band is £325,000 per person.

An additional residence nil-rate band of up to £175,000 may apply when a qualifying home passes to direct descendants.

Unused allowances can potentially transfer between married couples and civil partners.

Consequently, some qualifying couples can pass on estates worth up to £1 million without inheritance tax.

However, this is not an automatic allowance for every family.

The calculation depends on property ownership, available reliefs and the beneficiaries.

These factors become especially important when assessing inheritance tax after the second parent’s death, when unused allowances from the first death can affect the final liability.

If the government eventually extended the gifting period, estates containing significant historical transfers could face additional complications.

Nevertheless, families should not assume their inheritance tax bills will increase before any official legislation is introduced.

The broader debate surrounding a 100% inheritance tax also demonstrates how politically sensitive inherited wealth remains.

Supporters of reform argue that inheritance tax exemptions can disproportionately benefit wealthy families.

Opponents argue that additional restrictions could discourage saving, investment and financial support between generations.

Advani and Sturrock’s Institute for Fiscal Studies research highlights the importance of inheritance tax design in addressing wealth inequality, particularly as inherited wealth becomes more significant relative to earnings.

Their research projected inheritance tax revenues rising to more than £15 billion annually by 2032–33 in 2023 prices, demonstrating why the structure of the tax deserves scrutiny.

What Should Families Consider Before the October Budget?

With the Budget approaching, families making substantial gifts should distinguish between existing legislation and speculative reforms.

The current seven-year rule remains in place.

There is no announced deadline requiring families to make gifts before 28 October 2026 to avoid a 10-year rule.

For households reviewing inheritance tax arrangements, several practical considerations remain relevant:

• Keep accurate records of significant gifts, including dates, values and recipients.
• Review existing inheritance tax exemptions before transferring substantial assets.
• Consider the implications of the confirmed April 2027 pension inheritance tax changes.
• Avoid making irreversible financial decisions based solely on speculative Budget reports.

Professional financial or legal advice may be appropriate where estate planning involves substantial assets, trusts or business ownership.

The most important development will be whether the Chancellor formally proposes changing the gifting period or introducing a lifetime allowance.

Any government proposal would also need to clarify transitional rules, exemptions and commencement dates.

For now, the John Healey inheritance tax AI proposal remains an exercise in potential tax reform rather than an announced change in the law.

The recommendations have brought renewed attention to how Britain taxes inherited wealth, but their financial consequences cannot be established until the government sets out its own policy decisions.

With the Budget scheduled for 28 October 2026, families and business owners will be watching for confirmed announcements rather than relying on AI-generated predictions.
