Why Naming Your Grandchildren as Direct Beneficiaries Minimises Multigenerational UK Tax Liability
Leaving assets directly to grandchildren rather than passing them first through your children's estates can eliminate one complete IHT charge. In a straightforward three-generation transfer, assets that pass from grandparent to child to grandchild face two separate 40% IHT charges in two separate estates. A direct bequest to grandchildren removes the second charge entirely.
The Two-Generation IHT Problem
When a grandparent dies and leaves their estate to their adult children, those assets enter the children's estates. When the children later die, the same assets, assuming they have not been spent, are taxed again in their estates at 40% on the portion above the nil-rate band.
This is not a theoretical concern. For families with meaningful property wealth, pension assets from April 2027, or investment portfolios, the cumulative IHT across two generational transfers can consume a very large proportion of the original capital.
A worked illustration shows the scale. A grandparent with a net estate of £800,000 (after applying their own nil-rate band of £325,000 and residence nil-rate band where applicable) faces IHT on the excess at 40%. If they leave to their child, the child receives the net-of-tax amount. If that child themselves has a taxable estate when they die, the inherited amount is exposed to 40% again.
Starting with £800,000 and assuming the nil-rate band has been used: First generation: 40% IHT leaves approximately £480,000 passing to the child. Second generation: if the child's estate is also above the threshold and that £480,000 is still held there, a further 40% leaves approximately £288,000 reaching the grandchild.
The grandchild has received £288,000 from an original £800,000. That is a combined loss of 64% to IHT across two generations. Passing the £800,000 directly to the grandchild, all else being equal, produces only one generation of IHT.
What this Widget is About: This interactive widget, created by My Tax Accountant, visually breaks down the powerful strategy of naming grandchildren as direct beneficiaries to minimise your family's Inheritance Tax (IHT) burden in the UK. It clearly explains how passing assets through two generations exposes your wealth to a potential "double tax trap," significantly diminishing the original capital. By bypassing the intermediate generation, you can eliminate an entire 40% tax charge, preserving much more of your hard-earned assets for your grandchildren's future. To get started, explore the informational sections to understand key tax concepts, including Residence Nil-Rate Band (RNRB) allowances and the crucial upcoming 2027 pension changes. Then, use the interactive Wealth Transfer Visualizer to input different estate values and instantly compare the financial impact of a traditional two-step inheritance versus a direct grandchild bequest.
The Direct Bequest: How It Works and What It Achieves
A direct bequest to grandchildren, specified in the will, passes assets to them as beneficiaries without the assets first forming part of the child's estate. The grandparent's IHT is calculated on their own estate in the normal way, and the grandchildren receive the net-of-tax inheritance.
The child's estate is never enriched by those assets, so there is nothing to tax at the child's death in respect of the same funds.
The tax saving depends on whether the child's estate would have been above the IHT threshold at their death. If the child had a modest estate and would have been within their own nil-rate bands, the second IHT charge might not have arisen anyway. The strategy is most valuable where the intermediate generation (the children) are themselves likely to die with sizeable taxable estates.
This is the planning question that most families do not ask early enough: what is my child's current and projected estate? If they are already well above the nil-rate threshold through property and pensions, allowing a large inheritance to pass through their estate simply adds to an already taxable position.
The Nil-Rate Band, RNRB, and Grandchildren
The nil-rate band for 2026/27 remains at £325,000. The residence nil-rate band is £175,000, transferable between spouses, giving a married couple a potential combined threshold of £1 million (£650,000 NRB plus £350,000 RNRB).
The RNRB is only available where the deceased's home passes to direct descendants. Grandchildren count as direct descendants for this purpose. A grandparent leaving their home directly to grandchildren can therefore claim the RNRB on that bequest, provided all other conditions are met.
The RNRB is tapered away at £1 for every £2 of estate above £2 million. For very large estates, it phases out entirely. Where the taper applies, the RNRB benefit is reduced or eliminated, and the home passing to grandchildren does not unlock the same relief.
For estates below or near the £2 million taper threshold, a direct bequest of the home to grandchildren uses the RNRB efficiently. Combining this with a direct bequest of other assets to grandchildren skips the intermediate generation entirely and removes the second IHT charge from the family's overall succession position.
The Child's Perspective: Potential Objections and Practical Realities
A grandparent who leaves assets directly to grandchildren is, in effect, bypassing their own children. This is a family decision as much as a tax decision, and the financial reality of the children's own position matters.
If the adult children need the inheritance to fund retirement, care, or other needs, leaving assets directly to grandchildren is not suitable regardless of the tax efficiency. The planning works when the intermediate generation has sufficient independent wealth and does not need to inherit.
A deed of variation is sometimes used as an alternative. If the grandparent's will leaves assets to the children and the children themselves later choose to redirect some or all of that inheritance to the grandchildren, the deed of variation executed within two years of the death is treated as if the original will had contained the redirection. The IHT is recalculated as if the grandchildren were the original beneficiaries. This gives the children the ability to make the decision after the death rather than the grandparent making it during their lifetime, preserving flexibility.
The deed of variation route requires all beneficiaries who are disadvantaged by the redirection to consent. It also requires the document to be executed correctly and, where the variation affects IHT, to include a specific election for the read-back treatment. The child who redirects is not making a gift for IHT purposes; the transfer is read back into the original estate.
Trusts as an Alternative to Outright Bequests to Grandchildren
Where grandchildren are young at the time of the grandparent's death, an outright bequest may be inappropriate. A minor receiving a direct inheritance holds it through trustees until they reach 18 (or age 18 under the statutory provisions) unless the will provides otherwise.
A discretionary trust or a bereaved minor's trust can hold the assets for the grandchildren's benefit while protecting the capital from misuse or early dissipation. The IHT treatment of a trust established under the will depends on the type of trust.
A discretionary will trust enters the relevant property regime and faces ten-year anniversary charges (up to 6% of the trust fund every ten years) and exit charges when assets leave the trust. These charges are lower than a full 40% IHT charge, but they are ongoing costs that accumulate if the trust holds assets for many years.
A bereaved minor's trust, available where a parent dies and the child inherits, has more favourable treatment. For grandchildren, the bereaved minor's trust is not generally available unless the grandparent was in a parental role. The alternative for grandchildren is a bare trust or an age 18-to-25 trust under section 71D IHTA 1984, which provides a degree of flexibility while limiting exit charges.
The key planning point is that the IHT saving from bypassing the intermediate generation applies regardless of whether the bequest is outright or through a trust structure. The choice between outright and trust is about control and protection of the funds, not the IHT efficiency of the generational skip.

Pension Changes From April 2027: A New Urgency
From April 2027, unspent pension funds will be included within the estate for IHT purposes. This is a fundamental change from the current position, where pension funds generally sit outside the estate and can be passed to any nominated beneficiary without IHT.
Under the pre-2027 rules, many grandparents use their pension as a tax-efficient legacy, nominating grandchildren as beneficiaries of the death benefits. The pension fund passes outside the estate, free of IHT, and the grandchildren receive either a lump sum or drawdown access.
From 6 April 2027, pension funds will be counted as part of the estate for IHT calculation purposes, though the mechanics of how this interacts with the pension scheme administrator's obligations and the distribution process are still being finalised by HMRC. The direction of travel is clear: a significant tax shelter is being removed.
This makes the 2026/27 tax year the last opportunity to plan pension nominations without the certainty of IHT exposure. For grandparents with significant pension funds, reviewing the nomination in conjunction with overall will and estate planning is pressing.
The combined effect of naming grandchildren in the will for non-pension assets, and the upcoming pension IHT changes, means that multigenerational planning needs to consider the pension fund as part of the taxable estate from 2027 rather than as a tax-free overflow.

Multigenerational UK Tax Planning via Direct Bequests to Grandchildren
Inheritance Strategy | Primary Tax Benefit | Key Conditions & Rules | Impact on Multigenerational Liability |
Direct Bequest to Grandchildren | Skips a 40% IHT charge by bypassing the middle generation's taxable estate entirely. | Assets must be gifted directly in the Will; utilises the donor's Nil Rate Band (£325,000) and/or lifetime exemptions. | Prevents double taxation by ensuring assets are taxed once rather than twice (once on the grandparent's death and again on the child's). |
Deed of Variation | Allows children to redirect inheritance to grandchildren as if it came from the original deceased. | Must be executed within 2 years of death; all affected beneficiaries must agree; must include a statement for tax purposes. | Immediately removes assets from the child's taxable estate, preventing a "second hit" of IHT when the child eventually dies. |
Residence Nil Rate Band (RNRB) Utilisation | Provides an additional tax-free threshold (up to £175,000 per person) for a main residence. | Property must be "closely inherited" by direct descendants (including grandchildren); subject to tapering for estates over £2 million. | Maximises the total tax-free threshold (NRB+RNRB) for the family unit, shielding the family home from 40% IHT. |
Trust-Based Strategies (Bare & Discretionary) | Assets grow outside the estates of both grandparents and parents; utilises the grandchild's tax allowances. | Grandchild has absolute right at 18 (Bare Trust); Discretionary Trusts are subject to 10-year periodic and exit charges. | Ensures capital is not subject to IHT during the parents' lifetime and protects assets from being taxed as part of any individual's estate. |
Lifetime Gifts to Grandchildren: The Annual and Exemption Routes
Naming grandchildren in the will is one tool. Reducing the estate during lifetime through gifts is another, and the two work in combination.
The annual gift exemption of £3,000 per year allows a grandparent to give up to £3,000 to any combination of beneficiaries, free of IHT, each tax year. One prior year's unused exemption can be carried forward, potentially allowing £6,000 in a single year if the previous year's allowance was fully unused.
Wedding gifts to grandchildren attract a specific exemption of £2,500 per grandchild (or £5,000 per child). This is per grandchild, per occasion, and must be given before or on the wedding day.
Regular gifts from surplus income are the most powerful of the lifetime exemptions, and they are available without any monetary limit. Where a grandparent gives regular amounts to grandchildren from their income, in a pattern that does not reduce their standard of living and that forms part of their habitual expenditure, those gifts are exempt from IHT as normal expenditure out of income. The documentation requirement is a record of income, expenditure, and the pattern of gifts, retained to support the estate's IHT return after death.
Larger gifts above these exemptions are potentially exempt transfers. A PET made more than seven years before death falls outside the estate entirely. A PET within seven years is brought back into the estate, with taper relief reducing the IHT charge for gifts made more than three years before death.
For a grandparent whose health is reasonable and who has a seven-year horizon, large gifts directly to grandchildren now reduce the estate efficiently. For a grandparent with a shorter probable horizon, the taper still provides partial relief, and the alternative of a trust arrangement may allow a gift to be made with less uncertainty about timing.
Income Tax and the Grandchildren Receiving Assets
Where grandchildren inherit assets and those assets produce income, the income is taxed in the grandchild's hands. If the grandchild is a minor, the income from assets given to them by their parents (not grandparents) is treated as the parents' income under the parental settlement rules if it exceeds £100 per year. However, the parental settlement rules do not apply to gifts from grandparents. Income from assets given by a grandparent is taxed as the grandchild's income, not the grandparent's.
A grandchild who is a basic rate taxpayer, or who has income below the personal allowance of £12,570, pays little or no income tax on investment income from inherited or gifted assets. A grandparent in the additional rate band paying 45% on investment returns can therefore pass income-producing assets to a grandchild who has unused personal allowance or basic rate capacity, producing a substantial reduction in the family's total income tax.
This income-splitting benefit works alongside the IHT skip. Not only does the asset pass to the next-next generation without a second IHT charge, but the income it produces is taxed at a lower rate in the grandchild's hands than it would have been in the grandparent's.
The practical route for lifetime transfers is a gift, which is a PET for IHT and starts the seven-year clock. Alternatively, assets can be passed under the will on death. Either way, the income tax efficiency from the lower-taxed grandchild is available from the point the asset transfers.
The Scottish Position
Scottish income tax rates do not affect IHT, which is reserved UK legislation. The IHT analysis in this article applies equally to Scottish estates. The nil-rate band, RNRB, and the 40% rate are the same for UK residents anywhere in the country.
Where the income tax efficiency of transferring assets to grandchildren is relevant, Scottish grandchildren may be in a different income tax position from English or Welsh grandchildren. The Scottish basic rate applies above a lower threshold than the UK-wide threshold, which could affect the income tax saving from the transfer depending on the grandchild's total income.
The practical consideration is minor. The IHT skip benefit is the primary driver of the strategy, and that is UK-wide. The income tax differential between jurisdictions affects the quantum of secondary savings but does not change the fundamental logic.
A Practical Framework for Will Review
For any grandparent reviewing their will in light of multigenerational IHT planning, the following questions structure the analysis:
What is my child's current estate? If your child is already above the nil-rate band and RNRB in their own right, anything they inherit adds to a taxable estate.
What is the likely gap between your death and your child's death? The longer the time frame, the more exposure there is to a second generation of IHT.
Are my grandchildren old enough for an outright bequest, or does a trust structure provide better protection for young beneficiaries?
Is the home included in the estate? If so, using the RNRB by directing the property to grandchildren (directly or through a qualifying trust) is relevant.
What is the pension fund position, given the changes from April 2027? Pension nominations should be reviewed alongside the will rather than treated as a separate exercise.
Have I considered lifetime gifts as a supplement to the will? Regular gifts from income, using the normal expenditure out of income exemption, can reduce the estate over time without any seven-year risk.
Key Takeaways
Naming grandchildren as direct beneficiaries in a will bypasses one complete generation of IHT, potentially saving the combined effect of two 40% charges on the same assets.
The strategy is most effective when the intermediate generation (the children) have taxable estates in their own right. If the children's estates are within the nil-rate band, the second IHT charge may not arise regardless.
Grandchildren are direct descendants for RNRB purposes. A bequest of the family home to grandchildren can qualify for the £175,000 RNRB where conditions are met.
A deed of variation allows the children themselves to redirect an inheritance to grandchildren within two years of death, read back as if in the original will. This preserves flexibility if circumstances are uncertain at the time the will is drafted.
From April 2027, pensions will be included in estates for IHT. Pension nomination strategy needs to be integrated with will planning, not treated separately.
Gifts from surplus income to grandchildren during the grandparent's lifetime are exempt from IHT without limit, provided they are regular, habitual, and do not reduce the grandparent's standard of living. Documentation is essential.
Income from assets transferred to grandchildren is taxed as the grandchild's income, not the grandparent's, potentially producing a significant income tax saving alongside the IHT benefit.
FAQS
Q1: What are the key differences in inheritance tax outcomes when naming grandchildren directly versus leaving assets to your children first?
A1: Well, it's worth noting that in my experience advising families in Manchester and beyond, passing assets straight to grandchildren can prevent a second layer of IHT hitting when your children later pass away. If you leave everything to your children, it forms part of their estate, potentially pushing them over the £325,000 nil-rate band threshold (or up to £500,000 with the residence nil-rate band for the family home). Direct naming keeps it out of their estates entirely, preserving more for the grandchildren. Consider a retired couple with a £900,000 estate: by directing the excess directly, they might save their family tens of thousands that would otherwise be taxed twice across generations. Always review your will carefully, as this works best when children are financially secure.
Q2: How does the residence nil-rate band apply when skipping a generation to grandchildren?
A2: In my practice, this is one of those nuances that catches people out. Grandchildren qualify as direct descendants, so the additional £175,000 residence nil-rate band remains available if your main home passes to them, just as it would for children. This can mean a married couple potentially passing on up to £1 million tax-free. However, if your children are still alive and the home doesn't pass directly, you might lose this uplift unless structured properly through a will. I've seen a widow in Bristol benefit hugely by updating her will to name grandchildren explicitly for the property share, maximising the band without complicating her children's lives.
Q3: Are there risks involved in naming minor grandchildren as direct beneficiaries in a will?
A3: It's a common mix-up, but here's the fix from years of client cases: minors can't hold assets outright, so the inheritance typically goes into court-supervised guardianship or requires trustees until they reach 18 (or 21 in some cases). This can delay access and add administrative costs. To avoid pitfalls, many of my self-employed clients set up a discretionary trust in the will instead, giving flexibility for education or housing while still achieving the multigenerational IHT savings. Picture a builder from Leeds whose young grandchildren inherited via trust, it protected the funds from any family disputes and kept everything efficient tax-wise.
Q4: What happens if one of your children has significant debts or is going through divorce, does naming grandchildren directly help?
A4: Absolutely, and this is where direct naming shines for protection. Assets going straight to grandchildren generally stay out of your child's estate, shielding them from creditors or divorce settlements. In my experience with business owners in the Midlands, this has been a game-changer during turbulent times for the middle generation. However, it requires clear will drafting to prevent challenges. A practical tip: discuss intentions openly with your children beforehand to maintain family harmony while securing the tax and asset protection benefits.
Q5: Can lifetime gifts to grandchildren achieve similar multigenerational tax minimisation, and how do they interact with the seven-year rule?
A5: In practice, yes, regular gifts from surplus income or using annual exemptions (£3,000 per person) are immediately out of your estate and don't count towards the seven-year clock in the same way as larger Potentially Exempt Transfers (PETs). For bigger sums, surviving seven years makes them fully exempt. I've advised high-earning professionals who gifted into junior ISAs or education funds early, watching the growth escape their estate entirely. This complements will planning beautifully, especially for those with growing pensions or investments. Just keep records, as HMRC may scrutinise larger gifts.
Q6: How should business owners approach naming grandchildren as beneficiaries for shares or business assets?
A6: Business Property Relief can offer 100% IHT relief on qualifying assets, making direct transfers to grandchildren particularly powerful. By naming them in your will or using a trust, you can pass on the business or shares without IHT, and the relief often survives the transfer. One of my long-term clients, a shop owner near Birmingham, used this to ensure his grandchildren could benefit without the business being sold to pay tax in the children's generation. The key is ensuring the business qualifies and getting specialist valuation advice to avoid disputes.
Q7: Does naming grandchildren directly affect their own future tax liabilities, such as when they later inherit or sell assets?
A7: Generally, beneficiaries don't pay IHT on receipt, but they take the assets at market value for capital gains tax purposes. This can reset the base cost, potentially reducing future CGT on sale. However, if income-generating assets like rental properties are involved, the grandchildren will handle income tax on rents or dividends. In my advisory work, I've seen families minimise this by holding assets in tax-efficient wrappers or trusts. It's worth modelling scenarios, for instance, a grandchild inheriting shares might face lower overall family tax by skipping the middle layer.
Q8: What considerations apply for blended families or step-grandchildren when using this strategy?
A8: Step-grandchildren can qualify as direct descendants for the residence nil-rate band if treated as such, but clarity in your will is essential to avoid family challenges. In cases I've handled for remarried clients in London, explicitly naming step-grandchildren alongside biological ones ensured equal treatment and preserved the tax benefits. Without this, disputes can arise, potentially leading to costly probate delays. Professional drafting helps here, balancing fairness with IHT efficiency.
Q9: How do pensions and other death benefits fit into naming grandchildren as direct beneficiaries?
A9: Pensions often fall outside your estate if you nominate beneficiaries directly via the provider's form, bypassing IHT altogether in many cases (though rules are evolving). Naming grandchildren can extend this multigenerational advantage. I've guided clients with substantial pension pots to update nominations, ensuring funds go straight to the younger generation tax-efficiently. Always check with your provider, as discretionary trustee decisions can offer even more flexibility than strict beneficiary naming.
Q10: What common pitfalls should high-net-worth individuals watch out for when implementing this beneficiary strategy?
A10: One frequent issue I've encountered is failing to update nominations across all assets, bank accounts, ISAs, life insurance, which can undermine the plan. Another is underestimating the impact on means-tested benefits for grandchildren or overlooking interaction with trusts. For a tech executive client in Edinburgh, a comprehensive review of all holdings prevented leakage back into taxable estates. My advice: work with a qualified advisor for a full estate audit; it's an investment that pays dividends in peace of mind and saved tax across generations. Always confirm your specific situation, as individual circumstances vary.
