Can a Trust Reduce Inheritance Tax? UK Rules, Costs and Risks Explained

A trust is a legal arrangement in which trustees hold or manage assets for the benefit of other people, known as beneficiaries.

The person establishing the trust is generally called the settlor.

A trust can be established during someone's lifetime or through their will.

For example, a parent might establish a trust to hold investments for young children until they are old enough to manage money responsibly.

Alternatively, a will might provide for a surviving spouse to live in the family home during their lifetime, with the property ultimately passing to children.

Who Is Involved in a Trust?

The legal rights of the beneficiaries vary depending on the type of trust.

In some trusts, a beneficiary is absolutely entitled to the assets.

In others, trustees have discretion over whether, when and how beneficiaries receive funds.

These differences can have significant inheritance tax consequences.

No.

This is one of the most important misconceptions to address.

HMRC does not treat all trusts as separate tax-free containers.

Inheritance tax can arise when assets are transferred into a trust, while the trust holds them, when assets leave it or when someone with a relevant trust interest dies.

Some trusts are treated as part of a beneficiary's estate.

Others fall within the relevant property regime, which has its own inheritance tax charges.

The treatment depends on the legal structure rather than simply whether the word "trust" appears in a document.

A trust should never be established on the assumption that transferring legal ownership automatically eliminates inheritance tax.

Several trust structures are relevant to inheritance tax and family succession planning.

Bare Trusts

In a bare trust, the beneficiary is absolutely entitled to the trust assets, although trustees may hold legal title.

For inheritance tax purposes, an outright transfer into a bare trust for an individual is generally treated similarly to a gift to that beneficiary.

It may be a potentially exempt transfer.

If the donor survives seven years and does not retain a benefit, the gift will generally fall outside their estate.

However, the assets are normally treated as belonging beneficially to the beneficiary.

They can therefore form part of that beneficiary's own estate.

A bare trust offers relatively limited long-term control once the beneficiary is legally entitled to demand the assets.

Discretionary Trusts

In a discretionary trust, trustees decide how and when to distribute assets among a defined class of beneficiaries.

For example, a trust might allow trustees to support children and grandchildren according to their individual circumstances.

This can provide flexibility where beneficiaries have different needs.

However, many discretionary trusts fall within the relevant property inheritance tax regime.

This can involve entry, periodic and exit charges.

Life Interest Trusts

A life interest trust gives a beneficiary a defined right, often to receive income or occupy a property.

For example, a surviving spouse may have the right to live in the family home for life, after which the property passes to children.

Certain qualifying life interest trusts created on death can be treated differently from discretionary trusts for inheritance tax.

An immediate post-death interest trust may qualify for spouse exemption treatment when established for a surviving spouse.

The trust assets may then be included in the spouse's estate when their interest ends on death.

Trusts for Vulnerable Beneficiaries

Certain trusts for disabled or vulnerable beneficiaries can qualify for special tax treatment where the statutory conditions are met.

These trusts can be particularly valuable where a beneficiary needs long-term financial support or assistance managing assets.

The purpose is not necessarily inheritance tax reduction.

It may be to provide structured financial protection while preserving appropriate flexibility.

A lifetime transfer into a discretionary trust is generally a chargeable lifetime transfer.

This differs from an ordinary potentially exempt gift to an individual.

The inheritance tax calculation considers the value transferred and relevant earlier chargeable transfers.

Where the chargeable amount exceeds the available nil-rate band, an immediate inheritance tax charge can arise.

The standard nil-rate band is £325,000 in 2026/27.

The lifetime inheritance tax rate is generally 20% where the trustees bear the tax.

Where the settlor pays the tax personally, the calculation can produce a higher effective cost because the tax payment itself increases the value transferred.

Example: Placing £500,000 Into a Discretionary Trust

Consider someone who transfers £500,000 in cash into a discretionary trust.

Assume:

• They have made no chargeable transfers in the previous seven years.
• Their full £325,000 nil-rate band is available.
• No special reliefs or exemptions apply.
• The trustees bear the inheritance tax.

The transfer may therefore create an immediate inheritance tax liability of £35,000.

If the settlor pays the tax from additional personal funds, the grossed-up calculation differs.

The trust may also face future charges.

This illustrates why placing a substantial sum into trust is not automatically a tax-free transaction.

A chargeable lifetime transfer can be reassessed if the settlor dies within seven years.

The inheritance tax calculation may then use the death rate of 40%, with credit for relevant inheritance tax already paid.

Taper relief may be available in appropriate circumstances.

Earlier chargeable transfers can affect the calculation.

The estate and trustees may also have reporting or payment obligations.

For this reason, the seven-year rule does not operate in precisely the same way for transfers into discretionary trusts as it does for ordinary gifts to individuals.

Where substantial trust transfers are contemplated, the full transaction history should be reviewed.

Many discretionary trusts are subject to a periodic inheritance tax charge at each ten-year anniversary.

This is commonly called the ten-year charge.

The maximum effective rate is generally 6% of the relevant property value, although the actual calculation is more complicated.

It depends on factors including the trust's value, available nil-rate band, relevant earlier transfers and other statutory adjustments.

Example: A Trust Worth £600,000 After Ten Years

Suppose a discretionary trust holds investments worth £600,000 at its tenth anniversary.

Assume the full £325,000 nil-rate band is available for the simplified calculation, with no other adjustments or reliefs.

This is a simplified illustration, not a complete statutory ten-year charge calculation.

The actual rate may differ depending on the trust's history and circumstances.

The important point is that a trust can face inheritance tax charges during its lifetime even if the settlor is no longer alive.

An exit charge can arise when relevant property leaves a trust or when certain interests come to an end.

For example, trustees may decide to distribute investments to an adult beneficiary.

The inheritance tax calculation may produce an exit charge.

The rate depends on the trust's history, timing and applicable statutory rules.

It is not automatically 6% on every distribution.

Some distributions may produce little or no inheritance tax.

Others can create a meaningful liability.

Trustees should establish the tax position before making substantial distributions.

Sometimes, but property trusts require particular caution.

A homeowner may be attracted to the idea of transferring their house into trust while continuing to live there.

However, transferring the legal title does not necessarily remove the house from their inheritance tax estate.

If the person continues benefiting from the property, the gift with reservation of benefit rules may apply.

What Is a Gift With Reservation of Benefit?

A gift with reservation arises where someone gives away an asset but continues to enjoy a benefit from it.

A common example is giving away a house while continuing to live there rent-free.

The property may remain within the donor's inheritance tax estate despite the transfer.

The same concern can arise where a home is placed into a trust and the settlor retains rights or benefits that bring the arrangement within the rules.

A trust does not automatically overcome these provisions.

Does Surviving Seven Years Solve the Problem?

Not necessarily.

If the settlor continues to reserve a benefit, the property may remain within the estate even after seven years.

The inheritance tax outcome depends on the actual arrangement.

There may also be pre-owned assets income tax implications in some circumstances.

Property trusts should therefore be examined for their legal and practical effects rather than marketed as guaranteed inheritance tax protection.

Yes.

The residence nil-rate band provides an additional inheritance tax allowance of up to £175,000 in 2026/27 where a qualifying home passes to eligible direct descendants.

For married couples and civil partners, unused allowances may be transferable.

However, the availability of this allowance depends on how the property passes to the descendants.

Some trust arrangements qualify.

Others do not.

Discretionary Trusts and the Residence Nil-Rate Band

A home left to an ordinary discretionary trust does not generally qualify for the residence nil-rate band simply because children are included among the potential beneficiaries.

This is because the children are not necessarily treated as inheriting the property on the deceased's death.

There are special provisions for certain qualifying trusts and post-death arrangements.

The precise drafting and administration can therefore affect the outcome.

Life Interest Trusts and the Residence Nil-Rate Band

A qualifying life interest arrangement for a direct descendant may satisfy the residence nil-rate band requirements.

A life interest trust for a surviving spouse can also preserve the possibility of residence nil-rate band being available on the survivor's subsequent death, depending on the circumstances.

However, the trust must meet the relevant statutory requirements.

It is important to distinguish a qualifying immediate post-death interest from other arrangements that may look similar in everyday language.

A life interest trust can be useful where someone wants to provide accommodation for a surviving spouse while directing the eventual destination of the property.

For example, a husband and wife may each have children from previous relationships.

They may want the survivor to remain in the family home but ultimately preserve their respective shares for their own children.

A properly drafted will trust can sometimes help achieve that balance.

Example: A Blended Family

Consider a couple who own their home as tenants in common.

Each owns a 50% beneficial share.

One spouse dies and leaves their share into a qualifying life interest trust.

The surviving spouse has the right to occupy the property under the trust terms.

When the survivor dies, the trust share passes to the beneficiaries identified by the first spouse.

This may help preserve the first spouse's intended inheritance arrangements.

However, it does not automatically remove the trust share from inheritance tax.

A qualifying immediate post-death interest for the surviving spouse will generally bring the trust property into the survivor's estate for inheritance tax purposes.

The principal benefit may therefore be control over succession rather than a direct inheritance tax saving.

Trusts can sometimes help manage the exposure of assets to beneficiaries' financial circumstances.

For example, trustees may retain discretion over distributions rather than giving a beneficiary immediate absolute ownership.

However, trusts do not guarantee protection against divorce, bankruptcy or creditor claims.

Courts may examine the trust's structure, the beneficiary's rights, the history of distributions and the surrounding circumstances.

Arrangements created to defeat legitimate claims can also face legal challenges.

Trusts should not be described as making assets automatically untouchable.

Their effectiveness depends on proper drafting, administration and the relevant law.

A trust does not guarantee that assets will be disregarded when assessing care funding.

In England, local authorities can examine whether someone has deliberately deprived themselves of assets to reduce care charges.

A transfer into trust may be considered under these rules.

There is no general seven-year safe harbour for care funding assessments.

The local authority's decision depends on the relevant statutory tests and circumstances.

The rules differ across the UK's nations.

Homeowners should therefore be cautious about arrangements promoted as guaranteed care-fee protection.

Any proposed trust should be assessed for legitimate estate planning objectives as well as its care funding implications.

Potentially.

Transferring assets into trust can constitute a disposal for capital gains tax purposes.

Where assets have increased in value, a chargeable gain may arise.

Certain reliefs, including Gift Hold-Over Relief, may be available where the statutory conditions are satisfied.

However, these reliefs generally defer a gain rather than eliminate it permanently.

The trustees may subsequently face capital gains tax when assets are sold or transferred.

Trusts also have their own income tax treatment.

The overall tax position can therefore be more complicated than holding assets personally.

A proposed trust should be reviewed across inheritance tax, capital gains tax and income tax rather than considering only one tax.

The cost depends on the trust structure, the assets involved and whether professional trustees or advisers are required.

A relatively straightforward will trust may involve different costs from a lifetime discretionary trust holding property, investments or business interests.

Potential costs include:

There is no single reliable fee that applies to every trust.

The important question is whether the likely benefits justify the establishment and ongoing administration costs.

Many trusts must be registered with HMRC's Trust Registration Service.

Some trusts must register even where they have no immediate tax liability.

Other arrangements benefit from exclusions, provided the relevant conditions are met.

For example, certain will trusts may be excluded from registration where they are wound up within two years of death and meet the applicable requirements.

Trusts that become liable for relevant UK taxes may need to register even where an exclusion would otherwise apply.

Registration deadlines depend on the trust's circumstances.

Trustees should check the current HMRC rules rather than assuming that a trust created by a will never needs registration.

Trustees are responsible for administering the trust in accordance with its terms and the law.

Depending on the trust, their responsibilities may include:

• Safeguarding trust assets.
• Keeping accurate financial records.
• Considering beneficiaries' interests.
• Making and documenting distribution decisions.
• Obtaining appropriate investment advice.
• Meeting tax reporting and payment obligations.
• Maintaining relevant registrations.
• Reviewing the trust's continuing suitability.

Trustees may also need to resolve disagreements between beneficiaries or make difficult decisions about financial support.

A trust that appears simple when established can require decades of administration.

The choice of trustees is therefore as important as the initial drafting.

A trust may be useful where there is a genuine need to manage or protect assets for beneficiaries.

Examples include families with young children, vulnerable beneficiaries, blended families or business succession concerns.

A trust can also provide flexibility where future beneficiary circumstances are uncertain.

However, a trust may be less suitable where the primary objective is simply to avoid inheritance tax and the arrangement creates significant costs or restrictions.

Questions to Ask Before Establishing a Trust

1. What specific family problem is the trust intended to solve?
2. Who should benefit, and when?
3. What rights should beneficiaries have?
4. Who will act as trustees?
5. Can the settlor afford to give up control of the assets?
6. Will the transfer trigger inheritance tax or capital gains tax?
7. Could periodic or exit charges arise?
8. Will the residence nil-rate band be affected?
9. What are the likely administration costs?
10. Would a properly drafted will achieve the same objective more simply?

Clear answers can help distinguish a useful trust from an unnecessarily complicated arrangement.

Trust planning should begin with the family's objectives, not with the assumption that a trust will eliminate inheritance tax.

At Telmar Estate Planning, a review can help identify concerns involving inheritance arrangements, property ownership, beneficiaries and existing wills.

This may reveal situations where trust provisions deserve further consideration, particularly for blended families or vulnerable beneficiaries.

Detailed trust drafting, tax calculations, property transfers and ongoing administration may require specialist legal and tax advice.

The aim should be to select arrangements that are appropriate, understandable and sustainable over time.

Trusts can play an important role in estate planning.

They may help manage inheritances, protect vulnerable beneficiaries, support a surviving spouse or preserve intended family succession arrangements.

However, they do not automatically reduce inheritance tax.

Many discretionary trusts face potential entry, ten-year and exit charges.

Property trusts can also interact with gift with reservation rules and the residence nil-rate band.

For families considering a trust, the most useful starting point is to identify the problem it needs to solve and then assess the legal, tax and practical consequences.

A well-chosen trust may provide meaningful benefits. An unsuitable trust can create unnecessary cost and complexity.
