Inheritance Tax Reduction Strategies for UK Expats

With the standard UK IHT rate at 40%, reducing a future liability can make a material difference to the wealth ultimately passed to beneficiaries. However, there is no single method of minimising inheritance tax.

In practice, inheritance tax reduction strategies are usually most effective when several complementary approaches are planned together and implemented over a number of years. Lifetime gifting, trusts, available exemptions and reliefs, succession arrangements and residence planning can each serve different purposes within the same strategy.

Tax efficiency also needs to be balanced against your wider financial objectives, family circumstances, future liquidity requirements and the tax and succession rules that apply where you live and hold assets.

This article examines the principal inheritance tax reduction strategies available to UK expats and the cross-border considerations that can affect how they are used.

What Are the Primary Ways To Reduce UK Inheritance Tax?

For expats with complex residence histories and international assets, inheritance tax planning may involve several complementary strategies applied over many years.

As every expat’s circumstances are unique, successful inheritance tax planning focuses on several areas, including wider financial objectives, family circumstances, liquidity needs, and changing legislation in the UK and the country of residence.

UK expats can potentially reduce inheritance tax exposure through a combination of lifetime gifting, trusts, available exemptions and reliefs, succession planning and, where relevant, international residence planning. The appropriate combination depends on the value and composition of the estate, residence history, liquidity requirements, family circumstances and the tax rules of other relevant jurisdictions.

Key inheritance tax reduction strategies for UK expats include:

1. Lifetime gifting
2. Trust-based planning
3. Available exemptions and reliefs

Lifetime Gifting

Under UK IHT rules, you can make lifetime gifts that fall within available exemptions without creating an IHT liability on the gift. You can also make gifts above these exemptions, although their IHT treatment will depend on the recipient and the nature of the transfer.

Each tax year (6 April to 5 April), you have a £3,000 annual exemption. Any unused annual exemption can be carried forward for one tax year. You can also give unlimited amounts to your spouse or civil partner where the full spouse or civil partner exemption applies, or to qualifying charities. There are certain gifts that do not count towards the £3,000 annual exemption:

• Gifts for a wedding or civil partnership: You can give up to £5,000 to your child, £2,500 to your grandchild or great-grandchild, or £1,000 to anyone else on or shortly before their wedding or civil partnership.
• Regular gifts from your income: There is no fixed monetary limit where gifts qualify as normal expenditure out of income. Broadly, they must form part of your normal expenditure, be made from income, and leave you with enough income to maintain your usual standard of living.
• Small gifts: You can gift up to £250 per person if you have not used another exemption for the same recipient.

The Seven-Year Gifting Rule

Per His Majesty’s Revenue and Customs (HMRC), outright lifetime gifts to individuals that exceed available exemptions will generally be potentially exempt transfers (PETs), meaning no IHT is payable when the gift is made. Transfers into certain trusts follow different rules and can be immediately chargeable transfers.

If you (the transferor) pass away within seven years of making a PET, it may become chargeable for IHT purposes and will be taken into account when calculating the available nil-rate band and any IHT due. Depending on the time that has passed between making the gift and your death, taper relief may reduce the tax payable on the taxable part of the gift:

Taper relief reduces the tax due on a chargeable gift rather than reducing the value of the gift itself. It will generally only make a difference where cumulative chargeable gifts exceed the available nil-rate band.

After your death, executors may need to report lifetime gifts to HMRC, particularly gifts made within the seven years before your death. Keeping detailed records of the gifts you make during your lifetime can save significant time, minimise the risk of errors, and simplify the administration of your estate. This is particularly important if you make regular gifts from surplus income and intend to rely on the normal expenditure out of income exemption.

As HMRC may require information about gifts on forms IHT400 and IHT403, the records you keep should reflect the information requested on the forms:

1. Date of the gift (DD/MM/YYYY)
2. Recipient’s name and their relationship to you
3. Description of the assets (for instance, cash, company shares, or property)
4. Value of the gift at the time it was made
5. The method of transfer (for instance, cash payment or bank transfer)
6. Purpose of the gift (for instance, birthday or wedding present)

If you are relying on the normal expenditure out of income exemption, you should also keep sufficient records of your income and expenditure to show that the qualifying conditions were met.

What To Consider When Developing a Gifting Strategy

A successful gifting strategy requires careful consideration of several factors that inform the appropriate approach:

• Potential IHT liability for the recipient: If you pass away within seven years of making a gift, the recipient may become responsible for IHT attributable to the gift. Notifying them of the potential liability can help them understand their obligations and plan accordingly.
• Family relations: Gifts within the family can lead to disputes, particularly if you give gifts of unequal value to family members or do not communicate your intentions clearly.
• Future financial requirements: You may need significant assets for purchasing a property in your country of residence, funding your children’s education, or covering healthcare costs. Retaining sufficient funds for your own financial security should remain an important consideration.
• Timing: Rather than offering an immediate IHT-reduction solution, a gifting strategy requires a long-term approach and careful planning. Strategic timing of gifts over the years can help you use available exemptions and reduce the value of assets remaining in your estate.

For expats, a gift may also have tax or succession consequences in the country where you live, where the asset is located or where the recipient lives. These should be considered before assets are transferred.

Because the effectiveness of lifetime gifting depends on the gifts’ interaction with exemptions, the wider estate, and your individual circumstances, professional advice can help ensure the strategy is structured appropriately. Professional advice can also help establish how lifetime gifting could fit alongside your wider estate, investment and cross-border planning, while ensuring that sufficient capital remains available for your own future requirements.

Trust-Based Planning

Trusts are legal arrangements in which you (the settlor) transfer assets to trustees to hold and manage them for the benefit of one or more beneficiaries. There are different types of trusts you can establish, and some are particularly relevant for inheritance tax reduction purposes:

1. Discounted gift trusts
2. Loan trusts

Trusts do not automatically remove assets from the scope of IHT. Their treatment depends on the type of trust, the rights retained by the settlor and the assets involved.

Discounted Gift Trusts

A discounted gift trust (DGT) is an IHT planning arrangement in which you transfer assets into a trust while retaining defined rights to predetermined capital payments, usually for life or until the available funds are exhausted.

DGTs are typically funded using investment bonds (onshore or offshore), as they can:

• Provide the potential for medium- to long-term investment growth
• Allow investment returns to accumulate within the bond without requiring regular income payments

For IHT purposes, the value transferred into a DGT can be less than the amount originally invested because the settlor retains rights to future payments. The open-market value of those retained rights is taken into account when calculating the value transferred. The difference is commonly known as the discount.

The size of the discount is not fixed. It depends on the value of the retained rights and factors such as the settlor’s age and health when the arrangement is established.

There are two main types of DGTs:

• Absolute (bare) DGTs: With an absolute DGT, the beneficiaries are normally fixed from the outset and the settlor cannot subsequently replace them. The value transferred for IHT purposes is generally considered a potentially exempt transfer (PET).

  If you pass away within seven years of establishing the trust, the PET may become chargeable. IHT may then arise depending on the value of the transfer, other relevant lifetime gifts and the nil-rate band available. Taper relief may reduce the tax payable on the taxable part of the gift where more than three years have passed between the transfer and death.

•  Discretionary DGTs: With a discretionary DGT, you nominate a group of potential beneficiaries, while the trustees decide how and when to distribute assets among the group. Transfers into discretionary trusts are generally treated as chargeable lifetime transfers (CLTs), which may trigger an immediate IHT charge where the cumulative chargeable transfers exceed the available nil-rate band.

  The lifetime rate is generally 20%, although the effective rate can be higher where the settlor pays the tax. If you die within seven years, the original lifetime transfer is reassessed for IHT purposes and an additional charge may arise, with credit given for qualifying lifetime IHT already paid.Taper relief can apply to the additional tax where the relevant conditions are met. Surviving seven years generally removes the possibility of an additional death-related charge on the original lifetime transfer. However, a discretionary DGT can remain within the relevant property regime and may still be subject to 10-year anniversary and exit charges.

Loan Trusts

Loan trusts are legal arrangements in which you lend funds to the trust and retain the right to repayment of the outstanding loan. The funds lent to the trust are typically invested in onshore or offshore investment bonds.

Since establishing a loan trust does not involve giving away the amount lent, the outstanding loan remains part of your estate for IHT purposes. The planning objective is to freeze that part of your estate at the value of the outstanding loan, so that future investment growth does not normally increase the value of the loan asset in your estate.

With every repayment you receive, the outstanding loan reduces. Your estate will only reduce correspondingly if the repayment does not remain in your estate, for example because it is spent or subsequently gifted.

You can receive repayments only up to the amount outstanding on the original loan.

If you no longer need access to your outstanding loan, it may be possible to waive some or all of your right to repayment. A waiver is a further transfer of value for IHT purposes, and its treatment depends on the terms and type of trust. In addition to waiving the right to the outstanding loan, you may be able to:

1. Waive the loan in instalments: Where the relevant conditions are met, the annual £3,000 gift exemption, including any available carry-forward, may be used against transfers of value arising from partial loan waivers.
2. Transfer the repayment right to a spouse or civil partner: These transfers can generally benefit from the spouse or civil partner exemption for IHT purposes, subject to the conditions for that exemption.

There are two principal types of loan trusts:

• Absolute loan trusts

They require you to nominate your beneficiaries and specify the beneficial entitlement from the outset. The trust fund is not normally subject to the relevant property regime that imposes periodic and exit IHT charges on discretionary trusts.

• Discretionary loan trusts

They require you to name potential beneficiaries and allow trustees to control who benefits from the trust, in what capacity, and when. Discretionary loan trusts can fall within the relevant property regime. Depending on the trust’s taxable value and history, 10-year anniversary charges of up to 6% and proportionate exit charges may apply.

When Might Trust-Based Inheritance Tax Planning Be Appropriate?

Before setting up a trust to reduce IHT exposure, it is crucial to understand the role of different trust types in your broader estate planning strategy.

For instance, loan trusts are useful in a long-term IHT reduction strategy because the outstanding loan remains within the estate while future growth on the trust investments does not normally increase that loan asset. They may suit those who:

• Do not want to relinquish access to their original capital entirely
• Want to retain the right to repayment of the outstanding loan
• Do not prioritise an immediate reduction of IHT exposure

Discounted gift trusts may be better suited for expats who:

• Do not need unrestricted access to the capital transferred
• Seek an immediate reduction in the value transferred for IHT purposes where a discount is available
• Wish to retain defined rights to fixed payments

Besides the trust type, other factors should be considered when setting up a trust:

• Future financial needs: As certain trusts can restrict access to your capital once you establish them, consider whether you will have sufficient funds to finance your lifestyle in the future.
• Long-term objectives: While trusts can reduce your estate’s exposure to IHT, they do not automatically place assets outside the IHT scope. Understanding the trust’s position in your broader estate planning strategy is key to setting realistic expectations and ensuring goal alignment.
• Charges: Trusts may help you reduce IHT exposure, but some can involve 10-year anniversary and exit charges, other tax liabilities and ongoing administration. Their costs and complexity should be considered against the potential estate-planning benefits.

For UK expats, the tax treatment of a trust also needs to be considered in the country of residence and any other jurisdiction connected with the settlor, trustees, beneficiaries or trust assets.

Other UK Inheritance Tax Exemptions and Reliefs

UK IHT legislation provides a range of exemptions and reliefs that, when used effectively, can reduce your IHT exposure:

1. Spouse/civil partner exemption
2. Charitable giving
3. Residence nil-rate band
4. Agricultural property and business property reliefs

Spouse/Civil Partner Exemption

The spousal exemption enables spouses or civil partners to transfer assets between themselves without incurring UK IHT where the full exemption applies. Transfers can occur during lifetime or after death.

For transfers on or after 6 April 2025, specific restrictions can apply where the transferor is a long-term UK resident and the recipient spouse or civil partner is not. Earlier transfers can fall under the previous domicile-based rules.

A non-long-term UK resident spouse or civil partner may be able to elect to be treated as long-term UK resident for IHT purposes, potentially allowing the full exemption to apply, although the wider IHT consequences of making the election need to be considered.

Charitable Giving

The standard IHT rate is 40%, but can be reduced to 36% through charitable giving, provided that certain conditions are met:

1. You leave at least 10% of the relevant baseline amount, calculated under the statutory rules, to qualifying charity. If the 10% test is not met, qualifying charitable gifts can still be exempt from IHT even though the reduced 36% rate does not apply.
2. The recipient must be a qualifying charity for UK IHT purposes.

Residence Nil-Rate Band (RNRB)

The RNRB is an inheritance tax allowance that can apply when your direct descendants (such as your children, grandchildren, or their spouses) inherit a qualifying residence after your death. The current RNRB is £175,000, and it can be applied only to homes that meet specific conditions:

1. You must have lived in the property as your residence at some time.
2. The property does not have to be in the UK, but it needs to be within the scope of UK IHT. If you are no longer a long-term UK resident, a non-UK property will generally fall outside the scope of UK IHT, so it will not attract the RNRB.

The amount of RNRB available cannot exceed the value of the qualifying residence passing to direct descendants. Unused RNRB can potentially be transferred between spouses or civil partners, subject to the relevant conditions.

If the estate exceeds £2 million, the RNRB will gradually decrease. For every £2 the estate is worth above £2 million, the RNRB will be reduced by £1. For instance, if your estate is worth £2,200,000, the RNRB will be reduced by £100,000. With an individual RNRB of £175,000, it would taper away completely once the relevant estate reaches £2.35 million.

Agricultural Property and Business Property Reliefs

Agricultural property relief (APR) and business property relief (BPR) are reliefs that can reduce UK IHT on qualifying farming and business assets, such as:

• Land or pasture used to grow crops or rear animals
• Certain agricultural buildings and property
• Agricultural shares and securities that meet the relevant conditions
• Shares in an unlisted company
• Certain interests in a qualifying business
• Land, buildings, or machinery used in a qualifying business

Prior to April 2026, qualifying assets could be eligible for relief of up to 100%. Under the rules applying from 6 April 2026, the combined amount of qualifying agricultural and business property that can receive 100% APR or BPR is generally limited to £2.5 million. Relief at 50% is available on qualifying relievable property above that allowance. Separate rules provide 50% BPR for certain shares admitted to trading on designated recognised stock exchanges.

Any unused amount of the £2.5 million allowance can be transferred to a surviving spouse or civil partner. This can increase the available 100% relief allowance to as much as £5 million for the survivor. Combined with two £325,000 nil-rate bands, this means a couple could, in appropriate circumstances, pass on up to £5.65 million before IHT, provided the relevant assets qualify and the allowances are available.

How Do New UK Residence Rules Affect Inheritance Tax Exposure?

In 2025, UK legislation governing inheritance tax exposure moved from a domicile-based system to a long-term UK residence-based one. Broadly, you are a long-term UK resident for a tax year if you were a UK resident in at least 10 of the 20 tax years immediately preceding it.

Under current rules, leaving the UK does not immediately end your estate’s UK IHT exposure if you have become a long-term UK resident. Depending on your residence history, you can retain long-term UK resident status for between three and ten tax years after leaving:

If you are a long-term UK resident, your personally held overseas assets can fall within the scope of UK IHT as well as your UK assets. Foreign trusts and other overseas structures require separate analysis. Under the rules applying from 6 April 2025, foreign settled property can also fall within the UK IHT regime depending on factors including the settlor’s long-term UK residence status, although specific and transitional rules can apply.

Once you cease to be a long-term UK resident, your exposure will generally return to UK-situs assets, subject to the rules applying to particular assets and structures.

Given the potential length of the tail period after relocation, residence planning has become an important part of long-term IHT planning for internationally mobile families. The date you leave the UK, your previous UK residence history and the timing of gifts or other transfers can all affect the result.

Reducing UK IHT exposure does not necessarily reduce the family’s overall succession-tax liability. Your country of residence, the location of assets and, in some jurisdictions, the position of your beneficiaries may create separate estate, inheritance, succession or gift-tax liabilities. Where the same assets are taxed in the UK and another country, a double-taxation treaty or UK unilateral relief may sometimes reduce double taxation.

For HNW expats, residence planning therefore needs to be coordinated with gifting, trusts, wills and succession arrangements rather than considered in isolation.

Can Pensions Be Used To Reduce Inheritance Tax Exposure?

UK pensions have historically often fallen outside of one’s estate, enabling expats to pass pension wealth to beneficiaries without triggering IHT in many circumstances.

From 6 April 2027, most unused pension funds and pension death benefits will be included in the value of a deceased person’s estate for inheritance tax purposes. The reforms were enacted in Finance Act 2026 and apply to deaths on or after 6 April 2027.

These changes affect the role of pensions in estate planning for UK expats. Bringing pension wealth into the estate calculation may increase the amount of IHT payable, but it does not mean every pension inherited by a beneficiary will automatically be taxed at 40%. The result will depend on the value and composition of the wider estate, available thresholds and any applicable exemptions.

Certain pension benefits remain outside the new rules, including death-in-service benefits payable from registered pension schemes and certain dependant’s scheme pensions.

Benefits passing to spouses or civil partners and qualifying charities can continue to benefit from the relevant IHT exemptions, subject to the normal conditions applying to those exemptions. For expats, the spouse or civil partner exemption may require particular attention where the individuals have different long-term UK residence statuses.

How Should HNW UK Expats Combine Inheritance Tax Reduction Strategies?

The most appropriate inheritance tax reduction strategy will depend not only on the size of your estate, but also on its composition, how much capital you need to retain and the degree of access or control you are prepared to relinquish.

For example, lifetime gifting may reduce the value of assets remaining in your estate, but requires you to be comfortable giving up ownership of those assets. A loan trust may be more appropriate where access to the original capital remains important, while a discounted gift trust can serve a different purpose where you are prepared to make a transfer but want to retain defined payment rights.

Residence history adds another dimension for UK expats. The timing of a move overseas can affect whether worldwide assets remain within the scope of UK IHT, while trusts, pensions, property and other assets may also be subject to tax or succession rules in another jurisdiction.

The objective is therefore not simply to identify individual ways to reduce inheritance tax liability. It is to establish which combination of gifting, trust, succession and residence strategies is appropriate for your estate without compromising your own liquidity requirements or wider financial objectives.
