Why the April 2027 IHT Rules matter more than many families realise

For many years, there has been a quiet assumption in UK estate planning.

The family home was in the inheritance tax calculation.
The bank accounts were in the inheritance tax calculation.
The investment portfolio was in the inheritance tax calculation.
But the pension — particularly a defined contribution pension, SIPP or personal pension — often sat outside the estate.

For many families, this was not an incidental point. It became the centre of the plan.

A client might say:

“My ISA is for me. My pension is for the children.”

Or:

“I will spend my savings first and leave the pension untouched, because that passes more efficiently.”

For years, that approach was not unusual. In fact, it was often entirely rational. A pension was designed primarily to fund retirement, but in practice, unused pension wealth could also become a powerful succession planning tool. Where the scheme was discretionary, and death benefits were paid outside the estate, the pension could pass to beneficiaries without inheritance tax. Depending on the age of the member at death and the nature of the benefit, the income tax position could also be favourable.

That planning environment is now changing.

From 6 April 2027, most unused pension funds and pension death benefits will be brought within the value of a deceased person’s estate for inheritance tax purposes. In plain English, the pension that many families thought was “outside the estate” may become part of the estate.

That is a major shift.

It is not only a technical change for pension administrators. It is a practical change for families, executors, beneficiaries, internationally mobile individuals, business owners, and anyone who has treated their pension as a protected legacy asset.

A simple family story

Imagine a widower in London. Let us call him Robert.

Robert owns a home, has some cash and investments, and has built up a sizeable pension during his working life. He has two adult children. He has always understood that the house and investments would form part of his estate, but that his pension would normally pass separately under his expression of wishes form.

He has therefore drawn modestly from the pension. He has used his ISA, savings and other income first. His pension has remained relatively untouched.

His thinking was simple: the pension was tax-efficient, administratively separate, and intended eventually to benefit his children.

Now move the story forward to April 2027.

Robert dies after the new rules take effect. His executors begin the estate administration. They expect to deal with the property, bank accounts, investment accounts and household assets. But they now also need to identify, value and report pension wealth for inheritance tax purposes.

The pension is no longer just a pension issue. It becomes an estate issue.

That one change can alter the tax calculation, the administration process, the timing of probate, the cash-flow burden, and in some cases the amount ultimately received by the beneficiaries.

What exactly is changing?

From 6 April 2027, most unused pension funds and pension death benefits will be included in the deceased’s estate for inheritance tax purposes.

The change applies to deaths on or after 6 April 2027. If a person dies before that date, the current rules should apply even if the pension benefits are paid later.

The Government’s policy rationale is clear. HMRC considers that pensions have increasingly been used as a wealth transfer vehicle rather than purely as a retirement funding vehicle. The reform is intended to remove that perceived distortion.

In practical terms, however, many ordinary families will experience the change not as a policy correction, but as a new layer of complexity at the worst possible time: after the death of a loved one.

The headline is 40%, but the real issue is wider

Inheritance tax is often described as a 40% tax. That is broadly correct once the available nil-rate bands, exemptions and reliefs have been applied.

But the April 2027 pension reform is not just about a 40% charge on a pension pot.

It may affect:

the overall value of the estate;

whether the estate exceeds the residence nil-rate band taper threshold;

how much of the residence nil-rate band remains available;

whether the executors can pay the tax within the required timeframe;

whether beneficiaries receive pension benefits immediately or after delay;

whether pension beneficiaries and estate beneficiaries are the same people;

and how income tax interacts with inheritance tax on pension death benefits.

That last point is particularly important. Pension death benefits can still have an income tax dimension, especially where the member dies after age 75 or where taxable pension benefits are withdrawn by the beneficiary. The new regime is intended to avoid a crude double tax charge on the same gross amount, but the overall combined tax burden can still be materially higher than families expected.

This is where many simplistic online explanations are dangerous. The question is not merely: “Will pensions be taxed at 40%?”

The better question is:

“How does my pension now interact with my whole estate, my will, my beneficiaries, my residence nil-rate band, my spouse or civil partner position, my lifetime gifting strategy, and my family’s cash-flow needs after death?”

That is a very different question.

The executor’s job becomes harder

One of the most practical consequences is the burden on personal representatives — executors where there is a will, or administrators where there is no will.

From April 2027, personal representatives will be responsible for reporting and paying any inheritance tax due on pension assets brought within the estate.

This means that executors will need to identify pension arrangements. That may sound easy. In many cases it is not.

A person may have several old workplace pensions, a SIPP, a personal pension, a small deferred occupational scheme, or historic arrangements with providers that have merged, rebranded or changed administration platforms. For internationally mobile individuals, there may also be non-UK pension arrangements or historic overseas employment-related schemes.

The practical question becomes:

“Can the family actually find everything?”

If the answer is no, the estate administration becomes slower, more uncertain and more expensive.

Executors may need to contact pension providers, request date-of-death values, identify beneficiaries, understand whether benefits are excluded or exempt, and coordinate reporting with HMRC. In some cases, they may need to deal with pension scheme administrators before probate has been granted.

For many lay executors, that will be a significant burden.

The new withholding mechanism

HMRC has also set out a mechanism under which personal representatives may be able to direct pension scheme administrators to withhold part of taxable lump sum death benefits and pay inheritance tax directly to HMRC.

The broad intention is sensible: if inheritance tax is due on pension wealth, the tax should not be impossible to collect simply because the pension has already been distributed.

However, from a family perspective, this may create timing issues. Beneficiaries expecting to receive pension proceeds quickly may find that funds are delayed while the estate position is calculated. HMRC materials refer to the possibility of withholding 50% of taxable benefits for up to 15 months in certain circumstances.

That is not just a tax issue. It is a liquidity issue.

If the family was expecting pension proceeds to fund living costs, repay debt, equalise inheritances, pay school fees, fund care, or support a surviving partner, the timing of access may matter as much as the tax itself.

Important exclusions and protections remain

The new rules do not mean that every pension-related benefit will be subject to inheritance tax.

Certain benefits are expected to remain outside the new charge. These include, broadly, death in service benefits that meet the relevant conditions, dependants’ scheme pensions, and certain annuity arrangements.

Transfers to spouses and civil partners also remain central to inheritance tax planning, although the detailed outcome depends on the residence and status of the individuals involved and the relevant IHT rules applying at the time.

Charitable exemptions also remain relevant, and the 36% reduced inheritance tax rate may still apply where the necessary charitable giving conditions are met.

However, this is precisely why individual review is essential. The answer depends on the type of pension, the scheme rules, the beneficiary designation, the marital status of the individual, the residence status of the parties, the structure of the estate, and the terms of the will.

A pension is not just “a pension” for these purposes.

A defined contribution SIPP, an old final salary arrangement, a dependant’s pension, a death in service lump sum, a joint life annuity and a non-UK pension arrangement may produce very different results.

The residence nil-rate band trap

The pension change may also have an indirect effect on the residence nil-rate band.

Broadly, where a qualifying residence is left to direct descendants, an additional residence nil-rate band may be available. For married couples and civil partners, unused allowances may be transferable, meaning that in the right circumstances a couple’s estate may pass up to £1 million free of inheritance tax.

But there is a taper. Larger estates may lose some or all of the residence nil-rate band.

This is where pensions can produce a particularly unattractive result.

If unused pension wealth is added to the estate from April 2027, it may push the estate above the taper threshold. The result may not simply be inheritance tax on the pension. The estate may also lose part of an allowance that would otherwise have sheltered the family home.

In other words, the pension may increase the taxable estate twice: first by being included in the estate, and secondly by reducing the residence nil-rate band.

That is why “do nothing” may be expensive.

The cross-border angle: UK families with Italian or international connections

For internationally mobile families, the April 2027 change needs even more care.

Many Vectigalis Tax clients have UK pensions, Italian property, overseas bank accounts, non-UK family members, foreign succession law issues, trusts, companies, or a history of moving between tax systems.

For these families, the pension reform should not be reviewed in isolation.

A UK pension may be relevant to UK inheritance tax. Italian real estate may be relevant to Italian succession and tax rules. Beneficiaries may live in another jurisdiction. A surviving spouse may not have the same UK tax profile as the deceased. The individual may be a long-term UK resident for UK inheritance tax purposes but still have substantial non-UK assets and family connections.

The will may also be split between jurisdictions — for example, one will for UK assets and one for Italian assets — and the pension nomination may not align with either.

That can create a mismatch.

The will says one thing.
The pension expression of wishes says another.
The family expectation is different again.
The tax result follows neither family emotion nor informal intention.

This is where proper sequencing matters.

What should families do before April 2027?

The first step is not panic. It is also not rushing to withdraw pensions without advice.

The correct starting point is a structured review.

A sensible review should include the following.

First, identify all pension arrangements. This includes current workplace pensions, old workplace pensions, SIPPs, personal pensions, defined benefit arrangements, annuities, death in service benefits, and any overseas pension arrangements.

Second, obtain current values and understand the likely death benefit structure. The tax treatment may depend on whether benefits are lump sums, drawdown, dependant pensions, annuities, or other scheme-specific benefits.

Third, review expression of wishes forms. These are often out of date. They may name an ex-spouse, omit children born later, ignore grandchildren, or fail to reflect current family circumstances. They also need to be considered alongside the will, not separately.

Fourth, review the will. A will drafted when pensions sat outside the estate may no longer produce the intended tax or family result. Executors may need clearer powers. The allocation between beneficiaries may need reconsideration. Equalisation clauses may need to be revisited.

Fifth, model the inheritance tax position with and without pension inclusion. The numbers matter. It is not enough to say “there may be IHT”. Families need to know whether the pension causes a marginal issue, a material issue, or a structural problem.

Sixth, consider lifetime planning. For some clients, this may include drawing more from the pension during lifetime, making gifts, using normal expenditure out of income, funding life insurance written in trust, or restructuring how wealth is held. These strategies require care. Pension withdrawals may trigger income tax. Gifts may have inheritance tax consequences if the donor does not survive seven years. Trusts have their own tax regime. Insurance must be correctly written and funded.

Seventh, consider the surviving spouse or civil partner position. In many cases, passing pension benefits to a spouse or civil partner may remain efficient, but this depends on the wider estate plan and the tax profile of both individuals.

Eighth, consider liquidity. If inheritance tax will be payable within six months of death, how will it be funded? Will there be cash? Will assets need to be sold? Can the pension scheme pay HMRC directly? Are beneficiaries aligned on timing?

Finally, for internationally connected families, coordinate UK tax advice with foreign legal and tax advice. UK inheritance tax is only one part of the succession picture.

The question is no longer “Is my pension outside my estate?”

That was the old question.

The new question is:

“If I die on or after 6 April 2027, what does my pension do to my estate, my family, my executors, and my tax exposure?”

For some families, the answer will be manageable. The estate may remain below the relevant thresholds. The pension may pass to an exempt spouse. The death benefits may fall within an exclusion. The practical effect may be limited.

For others, the answer may be significant.

A pension that was once deliberately preserved as an inheritance tax-efficient asset may become taxable. It may push the estate into a higher-risk zone. It may reduce available reliefs. It may delay payments to beneficiaries. It may create a difficult administrative burden for executors.

The families who deal with this early will have options.

The families who ignore it may leave their executors with a tax problem, a cash-flow problem, and a family communication problem at exactly the moment when clarity is needed most.

Vectigalis Tax comment

The April 2027 pension inheritance tax reform is not simply a pension rule change. It is an estate planning reset.

For UK and international families, particularly those with UK pensions, overseas assets, Italian connections, trusts, companies, or non-UK beneficiaries, this should be reviewed now rather than shortly before implementation.

At Vectigalis Tax, we help individuals and families understand the UK inheritance tax consequences of pensions, succession planning and cross-border wealth structures. Our approach is practical, technically robust and designed to produce an HMRC-defendable action plan.

A proper review should not be limited to one isolated question. It should look at the will, pension nominations, asset ownership, residence status, spouse or civil partner planning, liquidity, lifetime gifts, trusts, and the interaction between UK and foreign tax rules.

The objective is simple: no surprises for the family, no unnecessary tax leakage, and no avoidable administrative burden for the executors.

If you have significant UK pension wealth, UK and overseas assets, or a family estate plan that has not been reviewed in light of the April 2027 rules, now is the time to revisit it.

Vectigalis Tax can assist with a focused inheritance tax and pension succession review, including a practical action plan for you, your family and your advisers.
