From 6 April 2027, new measures first announced in the Autumn Budget 2024 will come into force. These changes will bring most unused pension funds and death benefits into the scope of Inheritance Tax (IHT) from April 2027. This represents a major change to the tax treatment of pensions on death and will significantly broaden the IHT net by capturing assets that were previously excluded from tax.

Individuals with significant pension savings should review their estate plans carefully. Beneficiaries inheriting unused pension funds or death benefits may now face an IHT charge, making forward planning essential. Under the revised rules, personal representatives will be responsible for reporting and paying any IHT due, rather than pension scheme administrators.

There are important exclusions to note. Death-in-service benefits paid from registered pension schemes and dependants’ scheme pensions from either defined benefit arrangements or collective money purchase schemes will not fall within the scope of IHT. These will continue to be treated as before.

These reforms follow a technical consultation which concluded in January 2025 and led to changes in how liability is assigned. The new approach has raised concerns about potential issues such as payment delays, added administrative burden, and data privacy risks. As a result, close cooperation between personal representatives and pension providers will become increasingly important to ensure compliance and efficient estate administration.

Trustees must manage assets, follow tax rules, and register with HMRC where required.

A trust is a legal arrangement in which a trustee, either an individual or a company, is entrusted with managing assets such as land, money, or shares on behalf of others. These assets, placed into the trust by a settlor, are managed for the benefit of one or more beneficiaries.

Trustees are responsible for deciding how the trust's assets are to be managed, distributed, or retained for future use. They are also accountable for reporting and paying any tax due on behalf of the trust. If the trust pays or owes tax, it must be registered with HMRC.

Income received by a trust is subject to varying rates of Income Tax, depending on the type of trust.

Discretionary (or accumulation) trusts: Trustees pay tax on the trust's income. The first £500 is taxed at the standard rate. Income above this threshold is taxed at:

• 39.35% for dividend income
• 45% for all other types of income

Interest in possession trusts: Trustees are similarly responsible for paying tax on income. The rates are:

• 8.75% for dividend income
• 20% for all other income

There are additional trust structures, for example, bare trusts and settlor-interested trusts, which are subject to different rules and tax treatments. As a result, it is essential to consider both Income Tax and Capital Gains Tax (CGT) implications from the outset when establishing or managing any type of trust.

With the Residence Nil Rate Band (RNRB), families can pass on up to £1 million without IHT

The RNRB is an additional £175,000 Inheritance Tax (IHT) allowance that applies when a person’s main residence is passed to a direct descendant, such as a child or grandchild, after their death. The allowance is available to married couples and civil partners, and it can significantly reduce the IHT liability on family homes.

The RNRB is separate from and in addition to the standard IHT nil-rate band of £325,000. When combined with the standard threshold, a married couple or civil partners can potentially pass on up to £1 million tax-free to their direct descendants. This figure is based on two individuals each having a £325,000 nil-rate band and a £175,000 RNRB.

Importantly, any unused portion of the RNRB from the first spouse or civil partner to die can be transferred to the surviving partner, provided a claim is made to HMRC when the second partner dies. This transfer is not automatic and must be claimed. This is usually done by the executor of the estate during administration.

The RNRB is subject to tapering for larger estates. For estates valued over £2 million, the RNRB is reduced by £1 for every £2 over the threshold. As a result, estates significantly exceeding £2 million may lose the RNRB entirely, even if the home is passed to direct descendants.

Before probate begins, you must estimate the estate's value to see if Inheritance Tax applies. This includes valuing the deceased person's money, property and belongings in order to determine if Inheritance Tax (IHT) is due. This process is important even if you are not sure that any tax will be due.

There is usually no IHT to pay if the estate is valued under £325,000 or if anything above this threshold is left to a spouse, civil partner, charity or amateur sports club. If the person was widowed or passed on their home to children or grandchildren, the threshold may be higher.

To estimate the estate's value, you'll need to account for:

• All assets owned at death (homes, bank accounts, valuables, vehicles, investments etc).
• Any gifts made in the 7 years before death.
• The value of any trusts where the person had a beneficial interest.

You can estimate values yourself or use HMRC’s Inheritance Tax Checker to guide you. The checker helps identify whether IHT is likely to be due, but it does not calculate how much tax is due or notify HMRC.

When valuing assets, include joint property, pensions, or overseas items and assess their market value on the date of death. For gifts, consider their value when given, especially if the deceased still benefited from them (e.g., living rent-free in a gifted home).

You will also need to consider debts and check whether full reporting of the estate to HMRC is required.

Married couples can pass on up to £1 million tax-free if they plan their estates carefully.

The Inheritance Tax  (IHT) nil-rate band is currently £325,000. This means there is normally no IHT to pay if an estate is valued below this threshold. This amount can be higher if you leave everything above the £325,000 threshold to your spouse, civil partner, a charity or a community amateur sports club.

In addition, there is an IHT residence nil rate band (RNRB) of £175,000. This is a transferable allowance for married couples and civil partners (per person) when their main residence is passed down to a direct descendent such as children or grandchildren after their death. The allowance is available to the deceased person’s children or grandchildren.

Any unused portion of the RNRB can be transferred to a surviving spouse or partner. The RNRB is in addition to the £325,000 nil-rate band. The allowance is available to the deceased person's children or grandchildren. Taken together with the current IHT limit of £325,000 this means that married couples and civil partners can pass on property worth up to £1 million (£325,000 x 2 plus £175,000 x 2) free of IHT to their direct descendants. 

The transfer does not happen automatically and must be claimed from HMRC when the second spouse or civil partner dies. This is usually done by the executor making a claim to transfer the unused RNRB from the estate of the spouse or civil partner that died first.

There is a tapering of the RNRB for estates worth more than £2 million even where the family home is left to direct descendants. The additional threshold will be reduced by £1 for every £2 that the estate is worth more than the £2 million taper threshold. This can result in the full amount of the RNRB being tapered away.
