Inheritance tax (IHT) on UK trusts depends entirely on the trust type. Discretionary trusts fall under the “relevant property regime,” meaning they face a 20% entry charge on asset transfers exceeding the £325,000 threshold, a 10-year periodic charge of up to 6%, and an exit charge when assets leave the trust. Bare trusts generally escape these ongoing charges.
Key Takeaways:
- Relevant Property Regime: Most discretionary and accumulation trusts fall under the HMRC relevant property regime, making them distinct taxable structures separate from a settlor’s personal estate.
- 20% Trust Entry Charge: Asset transfers into a relevant property trust trigger an immediate 20% entry charge on any value exceeding an individual’s available £325,000 nil-rate band.
- The Seven-Year Rule: If a settlor dies within seven years of making a transfer, HMRC treats the transfer as a Chargeable Lifetime Transfer, which can increase the estate’s overall tax liability.
- Periodic and Exit Charges: Relevant property trusts face an ongoing 10-year periodic charge of up to 6% on excess assets, plus proportionate exit charges when capital is distributed to beneficiaries.
- Nil-Rate Band Freeze Until 2030: The standard £325,000 allowance is fixed by the government until April 2030, reducing long-term tax threshold flexibility.
- Loss of Residence Nil-Rate Band (RNRB): Moving a primary home into a lifetime discretionary trust disqualifies it from the £175,000 RNRB, as the property no longer passes directly to descendants.
- Business & Agricultural Relief Caps (April 2026): The 100% IHT relief for trust-held commercial or agricultural assets is capped at a combined value of £2.5 million, falling to 50% on any excess value.
- Pension IHT Integration (April 2027): Unspent pension savings will be brought fully into the scope of IHT from 6 April 2027, altering the tax utility of traditional Spousal Bypass Trusts.
- Exempt Trust Structures: Trusts for Bereaved Minors, Disabled Person’s Trusts, and Charitable Trusts qualify for specific statutory exemptions from standard periodic and exit charges.
- Trustee Compliance Mandate: Trustees are legally required to report all chargeable trust events, valuations, and payments using HMRC Form IHT100 rather than personal tax returns.
What Is Inheritance Tax on Trusts in the UK?
Inheritance Tax (IHT) is a tax charged on the transfer of wealth. While many people associate IHT with assets passing through an estate after death, trusts can also be subject to inheritance tax during a person’s lifetime and after assets have been transferred.
A trust is a legal arrangement where assets are held by trustees for the benefit of beneficiaries. Trusts are commonly used for estate planning, asset protection, succession planning, and supporting family members.
However, HMRC applies specific inheritance tax rules to certain trust structures to prevent individuals from avoiding tax simply by moving assets out of their personal estate.
The inheritance tax treatment depends on the trust type. Some trusts are treated similarly to direct gifts, while others fall within the relevant property regime, which creates ongoing inheritance tax obligations.
How Does the £325,000 Nil-Rate Band Apply to Trusts?
The nil-rate band is one of the most important concepts when considering inheritance tax on trusts.
Every individual currently has a £325,000 inheritance tax threshold. Transfers within this threshold are generally not subject to inheritance tax. Transfers exceeding the threshold may trigger tax liabilities depending on the circumstances.
It is important to note that the standard £325,000 nil-rate band threshold has been officially fixed by the government until April 2030.
Furthermore, while individuals can also qualify for an additional £175,000 Residence Nil-Rate Band (RNRB) when passing a family home directly to children or grandchildren, transferring a main residence into a lifetime discretionary trust typically disqualifies the property from this relief because it is no longer passing “directly” to your descendants.
When assets are placed into certain trusts during a person’s lifetime, the available nil-rate band is assessed at the date of transfer. Any previous chargeable lifetime transfers made within the preceding seven years can reduce the available allowance.
This means that someone who has already made significant lifetime gifts may have less nil-rate band available when establishing a trust.
How the Nil-Rate Band Can Affect Trust Transfers?
| Trust Transfer Value | Available Nil-Rate Band | Amount Above Threshold | Potential Entry Charge Exposure |
| £200,000 | £325,000 | £0 | None |
| £325,000 | £325,000 | £0 | None |
| £500,000 | £325,000 | £175,000 | Possible |
| £750,000 | £325,000 | £425,000 | Higher exposure |
| £1,000,000 | £325,000 | £675,000 | Significant exposure |
The actual tax payable depends on the trust type and other inheritance tax considerations.
What Happens When Assets Are Placed Into a Trust?
When assets are transferred into a trust, HMRC first examines whether the transfer is a chargeable event.
The value of the assets entering the trust is measured at market value. This could include cash, property, investments, business interests, or other valuable assets.
The transfer may trigger immediate inheritance tax consequences if the amount exceeds the available nil-rate band and the trust falls within the relevant property regime.
In addition, capital gains tax and other tax considerations may arise depending on the nature of the transferred assets.
What Is the Trust Entry Charge and When Does It Apply?
The entry charge is an inheritance tax charge that may arise when assets are transferred into certain trusts.
For relevant property trusts, the charge is generally based on the value transferred above the available nil-rate band. The maximum lifetime rate is usually 20% on the excess amount.
For example, if an individual transfers £600,000 into a discretionary trust and has the full £325,000 nil-rate band available, only the excess above £325,000 is potentially subject to the lifetime charge.
The entry charge can significantly influence whether a trust arrangement is appropriate, particularly for high-value estates.
Julian Washington, Partner at Irwin Mitchell, noted that trusts remain valuable estate planning tools but emphasised that the inheritance tax implications must be considered before assets are transferred because immediate tax liabilities can arise depending on the value and trust structure involved.
How Does the Seven-Year Rule Affect Trust Inheritance Tax?
The seven-year rule is one of the most widely discussed inheritance tax rules in the UK.
Where assets are transferred into certain trusts, surviving for seven years after the transfer can significantly affect the inheritance tax treatment. If the settlor dies within seven years, the transfer may still be considered when calculating inheritance tax liabilities.
This rule exists because HMRC seeks to prevent individuals from avoiding inheritance tax shortly before death by transferring assets away.
The practical impact of the seven-year rule often depends on:
- The trust type.
- The value transferred.
- Other lifetime gifts made.
- The timing of death.
For estate planning purposes, the seven-year period remains a crucial consideration whenever substantial assets are transferred into trust arrangements.
Impact of Recent UK Budget Changes on Trusts & Estates
The landscape of UK estate planning has shifted significantly due to recent legislative overhauls.
Anyone managing or establishing a trust must account for these major changes:
- Pensions Dragged Into IHT (Effective April 2027): Historically, residual pension pots could be passed to beneficiaries free of inheritance tax. From 6 April 2027, unspent pension savings will be brought entirely into the scope of IHT. This fundamentally changes the utility of traditional Spousal Bypass Trusts designed to hold lump-sum pension death benefits.
- Business and Agricultural Property Relief Caps (Effective April 2026): For trusts holding commercial or agricultural assets, 100% IHT relief will be capped at a combined asset value of £2.5 million. For any value exceeding this threshold, the relief drops significantly to 50%.
- Offshore Trust Exclusions (Effective April 2025): For trusts created from April 2025 onwards, non-UK assets will only retain their “excluded property” status if the settlor is not a “long-term resident” (defined as being a UK resident for at least 10 out of the last 20 tax years).
Which Types of Trusts Are Subject to Inheritance Tax Charges?
Not all trusts are taxed in the same way.
Some trusts are fully within the relevant property regime, while others receive different inheritance tax treatment because of their structure or purpose.
Understanding the differences is essential before choosing a trust arrangement.
Trusts That May Qualify for Special Treatment
Certain trusts receive special inheritance tax treatment under legislation.
- Trusts for Bereaved Minors: Designed for children under 18 who have lost a parent or step-parent. There are no ongoing IHT charges if the assets are held strictly for the minor and they become fully entitled to them by age 18.
- 18 to 25 Trusts: These allow young people to inherit later. While they are exempt from the standard 10-year anniversary charges, they can face specific IHT exit charges when assets leave the trust between the ages of 18 and 25.
- Disabled Person’s Trusts: These face no 10-yearly periodic charges or exit charges as long as the assets stay in the trust for the absolute benefit of the disabled individual. Lifetime transfers into these trusts are also exempt from initial charges, provided the settlor survives for 7 years.
- Charitable Trusts: Gifts made to a UK-registered charity or Community Amateur Sports Club (CASC) are completely exempt from IHT. Additionally, if an individual leaves 10% or more of their baseline estate to a qualifying charity through a Will Trust, the overall inheritance tax rate on the rest of the estate is reduced from 40% to 36%. Note that gifts to non-UK charities no longer qualify for this exemption.
The availability of exemptions and reliefs depends on specific statutory conditions being satisfied.
How Do 10-Year Anniversary Charges Work on Trusts?
The 10-year anniversary charge, often called the periodic charge, is one of the most important ongoing inheritance tax rules affecting discretionary trusts.
Every ten years, trustees must review the value of trust assets and calculate whether a periodic charge is payable.
The charge applies to relevant property trusts and is designed to ensure that trust-held assets continue to contribute towards inheritance tax revenues despite remaining outside a personal estate.
The maximum effective rate is generally 6% of the value exceeding the available nil-rate band.
Many trustees underestimate the importance of periodic charge calculations, particularly where trust assets have experienced substantial growth over time.
What Are Exit Charges and When Are They Payable?
Exit charges are inheritance tax charges that may arise when assets leave a relevant property trust. These charges are designed to complement the 10-year periodic charge system and ensure that trust assets remain subject to inheritance tax when distributed.
An exit charge can occur whenever trustees transfer assets to beneficiaries or when a trust is wound up and assets are distributed.
The amount payable is usually linked to the effective rate established during the most recent ten-year anniversary calculation. As a result, trusts that have already been subject to a periodic charge may also generate exit charges when capital leaves the trust.
The timing of distributions can significantly affect the amount of tax due, which is why trustees often seek professional advice before making major distributions.
How Are Exit Charges Calculated?
Exit charge calculations are among the more complex areas of trust taxation.
In simple terms, the calculation usually starts with the effective rate of tax established at the most recent ten-year anniversary. This rate is then adjusted according to the length of time between that anniversary and the date of the distribution.
As a result, distributions made shortly after a ten-year anniversary often attract a lower charge than distributions made several years later.
Because multiple variables can affect the outcome, trustees should maintain detailed records of:
- Previous trust valuations.
- Anniversary calculations.
- Asset distributions.
- Changes to trust assets.
Comparison of Trust Inheritance Tax Charges
| Type of Charge | When It Can Apply | Typical Maximum Rate | Main Trigger |
| Entry Charge | When assets enter certain trusts | 20% | Transfer above available nil-rate band |
| 10-Year Periodic Charge | Every tenth anniversary | Up to 6% | Value exceeding available threshold |
| Exit Charge | When assets leave a trust | Up to 6% (effective rate basis) | Distribution of trust assets |
This table highlights why trust planning requires consideration of both immediate and long-term inheritance tax implications.
What Happens If the Settlor Dies Within Seven Years of Creating a Trust?
The death of a settlor within seven years of creating a trust can significantly affect inheritance tax calculations.
When a transfer into trust is treated as a chargeable lifetime transfer, the value transferred remains relevant for inheritance tax purposes for seven years. If the settlor dies during this period, HMRC may reassess the transfer as part of the overall inheritance tax position.
The trust itself does not automatically lose its structure or protection, but the transfer may become chargeable at death rates depending on the circumstances.
This is why the seven-year rule plays such an important role in estate planning discussions.
Many individuals establish trusts with long-term planning objectives in mind, understanding that the tax advantages often become more effective the longer they survive after making the transfer.
James Ward, Partner and Head of Private Client Services at Kingsley Napley, has noted that lifetime gifting and trust planning can be highly effective but should always be viewed within the context of the seven-year inheritance tax framework and an individual’s wider estate planning goals.
How Do Life Interest Trusts Differ from Discretionary Trusts for Inheritance Tax?
Life interest trusts and discretionary trusts are often discussed together, but they operate very differently.
A life interest trust gives a beneficiary the right to receive income from trust assets or use specific assets during their lifetime. After their death, the underlying capital usually passes to other beneficiaries.
Discretionary trusts, by contrast, allow trustees to decide which beneficiaries receive benefits and when those benefits are provided.
From an inheritance tax perspective, life interest trusts may be subject to different rules depending on when they were established and whether they arose during the settlor’s lifetime or on death.
Many families use life interest trusts to balance the needs of a surviving spouse with the desire to preserve wealth for children or future generations.
For example, a parent may leave a property in trust, allowing their spouse to live in the property for life while ensuring that the property ultimately passes to their children.
Are Bare Trusts Subject to the Same Inheritance Tax Rules?
Bare trusts are generally treated differently from discretionary trusts.
Under a bare trust arrangement, the beneficiary has an immediate and absolute entitlement to the trust assets. The trustees simply hold the assets until they are transferred to the beneficiary.
For inheritance tax purposes, a transfer into a bare trust is often treated similarly to a direct gift to the beneficiary.
As a result, bare trusts do not usually fall within the relevant property regime and are not normally subject to:
- Ten-year anniversary charges.
- Exit charges.
- Ongoing relevant property taxation.
Instead, the seven-year gifting rules are typically the primary inheritance tax consideration.
This simpler tax treatment is one reason why bare trusts are commonly used for gifts to children and younger family members.
Can Trusts Help Reduce a Future Inheritance Tax Liability?
Trusts can form an important part of inheritance tax planning, but they should not be viewed as a guaranteed method of avoiding tax.
Their effectiveness depends on factors such as:
- The type of trust.
- The assets transferred.
- The value of the estate.
- The settlor’s life expectancy.
- Available reliefs and exemptions.
In many situations, trusts help remove future asset growth from an individual’s taxable estate. If the assets appreciate significantly after being transferred, that growth may occur outside the settlor’s estate for inheritance tax purposes.
This can be particularly valuable for investment portfolios, family businesses, and properties expected to increase in value over time.
However, these potential benefits must always be balanced against the entry, periodic, and exit charges that certain trusts may face.
Why Is Life Insurance Written in Trust Often Used for Estate Planning?
One of the most widely used inheritance tax planning techniques involves writing life insurance policies into trust.
When a life insurance policy is written into an appropriate trust structure, the policy proceeds can generally be paid directly to beneficiaries without forming part of the deceased’s estate.
This arrangement offers several advantages.
The funds can usually be accessed more quickly because they do not need to pass through probate. In addition, the policy proceeds may avoid increasing the value of the taxable estate.
As a result, beneficiaries can often receive funds more efficiently while reducing the risk of additional inheritance tax exposure.
Many families use life insurance trusts specifically to provide liquidity for inheritance tax liabilities that may arise elsewhere within the estate.
How Can a Spousal Bypass Trust Support Long-Term Wealth Protection?
Spousal bypass trusts have historically been used to receive lump-sum death benefits from pension schemes or employment-related benefits.
The objective is to keep the proceeds outside both spouses’ estates while still allowing access to funds if needed.
Although pension legislation and estate planning strategies have evolved over time, bypass trusts can still play a role in specific family circumstances.
Their primary attraction is the ability to preserve wealth for future generations while reducing the risk of assets becoming subject to multiple rounds of inheritance tax as they pass between family members.
Because pension and trust legislation continues to evolve, professional advice is particularly important before implementing this type of planning strategy.
What Common Mistakes Can Increase Inheritance Tax on Trusts?
Many inheritance tax problems arise not because of the trust itself but because of poor planning or administration.
Common mistakes include transferring assets without understanding the available nil-rate band, failing to account for previous lifetime gifts, overlooking ten-year anniversaries, and distributing assets without assessing potential exit charges.
Some trustees also fail to obtain accurate valuations when required. This can lead to reporting errors and potential disputes with HMRC.
Another frequent issue involves assuming that all trusts automatically avoid inheritance tax. In reality, many trust structures remain subject to ongoing tax charges throughout their existence.
By understanding the relevant rules and maintaining proper records, trustees can reduce the likelihood of unexpected tax liabilities.
When Should Professional Advice Be Sought for Trust and Inheritance Tax Planning?
Professional advice should ideally be sought before assets are transferred into a trust rather than after.
Inheritance tax rules affecting trusts are complex and can have long-term consequences that are difficult to reverse. A decision that appears tax-efficient today may create unexpected liabilities in the future if not structured correctly.
Solicitors, chartered tax advisers, estate planners, and financial advisers can help assess:
- Suitable trust structures.
- Potential inheritance tax exposure.
- Available exemptions and reliefs.
- Long-term family objectives.
- Trustee responsibilities.
Obtaining advice early often helps families avoid costly mistakes while ensuring that trust arrangements align with their estate planning goals.
How to File and Comply with HMRC Trust Regulations?
Trust reporting is strictly monitored by HMRC. When a chargeable event occurs, such as a lifetime transfer exceeding the nil-rate band, a 10-year anniversary, or a capital distribution, trustees cannot rely on standard personal tax returns.
You must report and pay inheritance tax using HMRC Form IHT100. Depending on the specific event, trustees will also need to attach specific supplementary schedules, such as Schedule IHT100a for initial lifetime transfers or Schedule IHT100c for calculating the 10-year periodic charge.
Failure to file or obtain accurate property and asset valuations can result in severe penalties and interest charges from HMRC.
Conclusion
Inheritance tax on trusts in the UK involves much more than simply transferring assets into a trust structure. Depending on the type of trust used, inheritance tax may arise when assets enter the trust, every ten years during the trust’s lifetime, and when assets are distributed to beneficiaries.
Understanding the nil-rate band, seven-year rule, entry charges, periodic charges, and exit charges is essential for effective estate planning. While trusts can provide valuable asset protection and succession planning benefits, they require careful administration and ongoing compliance.
Seeking professional advice before establishing a trust can help ensure that the chosen arrangement supports both family objectives and long-term tax efficiency.
Frequently Asked Questions
Do all trusts pay inheritance tax in the UK?
No. Different trust structures have different inheritance tax treatments. While many discretionary trusts fall within the relevant property regime, bare trusts and certain specialised trusts may be subject to different rules or exemptions depending on their circumstances.
How often is inheritance tax assessed on a discretionary trust?
Discretionary trusts that fall within the relevant property regime are generally assessed for periodic inheritance tax charges every ten years. Additional exit charges may also apply when assets are distributed between anniversary dates.
Can beneficiaries be taxed when receiving assets from a trust?
In some situations, beneficiaries may receive distributions without a direct inheritance tax liability. However, the trust itself may have already incurred an exit charge or other tax obligations before the distribution takes place.
Does placing a house into a trust avoid inheritance tax?
Not automatically. The inheritance tax consequences depend on the trust structure, the value of the property, whether the settlor continues to benefit from the property, and how long the settlor survives after making the transfer.
What forms are used to report inheritance tax charges on trusts?
Trustees commonly use inheritance tax reporting forms such as IHT100 and related schedules when reporting certain trust events. The exact reporting requirements depend on the nature of the chargeable event.
Can married couples use both nil-rate bands when creating trusts?
In some estate planning scenarios, married couples may effectively benefit from two nil-rate bands. However, the application of these allowances depends on how the trust is structured and the timing of transfers.
Are trust inheritance tax rules likely to change in the future?
Tax legislation is subject to periodic review and reform. While the core principles of trust inheritance tax have remained relatively stable, trustees and settlors should stay informed about future legislative changes that could affect planning strategies.
