Understanding Inheritance Tax in the UK: A Guide for 2025

Inheritance Tax (IHT) remains one of the UK's most complex and often misunderstood taxes. At MCC Partners, we regularly help clients navigate the intricate rules surrounding inheritance tax and implement effective strategies to protect their family's wealth. This guide explains the key aspects of inheritance tax, with particular focus on how the rules change for surviving spouses.

What is Inheritance Tax?

Inheritance Tax is a tax on the estate (property, money, and possessions) of someone who has died. It's paid on estates valued above a certain threshold, with the tax applied to the portion that exceeds this threshold.

The current standard rate of Inheritance Tax is 40%. However, with proper planning and understanding of the available allowances, many estates can reduce or even eliminate their inheritance tax liability altogether.

Understanding the Nil-Rate Band

The Nil-Rate Band (NRB) is the threshold below which no inheritance tax is payable. As of 2025, this stands at £325,000 per person.

This means that:

• If your estate is valued at £325,000 or less, there's no inheritance tax to pay
• If your estate exceeds this amount, inheritance tax is typically charged at 40% on the excess

The Residence Nil-Rate Band

In addition to the standard Nil-Rate Band, there's also the Residence Nil-Rate Band (RNRB). This is an additional allowance when a home is passed to direct descendants (children, grandchildren, etc.).

For the 2025/26 tax year, the Residence Nil-Rate Band is £175,000 per person.

However, it's worth noting that the RNRB begins to taper away for estates valued over £2 million, reducing by £1 for every £2 that the estate exceeds this threshold.

Inheritance Tax for Surviving Spouses: The Transferable Nil-Rate Band

One of the most significant aspects of inheritance tax planning involves understanding how allowances work for married couples and civil partners.

Spousal Exemption

Assets passed between spouses or civil partners are exempt from inheritance tax. This means that regardless of the value, a surviving spouse can inherit their deceased partner's assets without any immediate inheritance tax liability.

Transferring Unused Allowances

When the first spouse or civil partner dies, any unused portion of their Nil-Rate Band and Residence Nil-Rate Band can be transferred to the surviving spouse.

Here's how this works in practice:

Scenario 1: First spouse leaves everything to surviving spouse

• First spouse dies and leaves entire estate to surviving spouse
• No inheritance tax is due (spousal exemption)
• 100% of their £325,000 NRB remains unused
• 100% of their £175,000 RNRB remains unused
• These unused allowances can be transferred to the surviving spouse

Scenario 2: First spouse uses part of their allowance

• First spouse dies and leaves £100,000 to children and remainder to spouse
• £100,000 uses part of their NRB, leaving £225,000 unused (approximately 69%)
• 69% of their NRB can be transferred to the surviving spouse

Maximum Combined Allowances for a Surviving Spouse

When the surviving spouse later dies, their estate can benefit from:

• Their own £325,000 Nil-Rate Band
• Their own £175,000 Residence Nil-Rate Band (if applicable)
• Any transferred percentage of the deceased spouse's NRB (up to £325,000)
• Any transferred percentage of the deceased spouse's RNRB (up to £175,000)

This means a surviving spouse could potentially have combined allowances of up to £1,000,000 before any inheritance tax becomes payable (£325,000 + £325,000 + £175,000 + £175,000).

Example: How Transferable Allowances Work

Example: John and Mary are married. John dies in 2025 and leaves his entire estate to Mary.

• No inheritance tax is payable on John's death due to spousal exemption
• 100% of John's NRB (£325,000) remains unused
• 100% of John's RNRB (£175,000) remains unused (assuming they owned a property)

When Mary dies later:

• Her estate can claim her own NRB (£325,000)
• Her estate can claim her own RNRB (£175,000)
• Her estate can claim John's transferred NRB (£325,000)
• Her estate can claim John's transferred RNRB (£175,000)

This gives Mary's estate a total tax-free allowance of £1,000,000. Only if her estate exceeds this amount will inheritance tax be due, and only on the excess.

Other Important Inheritance Tax Exemptions and Reliefs

Annual Gift Allowance

Each person can give away £3,000 per tax year inheritance tax-free. This allowance can be carried forward one year if unused.

Small Gifts Exemption

Gifts of up to £250 per person per tax year are exempt, provided they haven't received any part of the £3,000 annual exemption.

Normal Expenditure Out of Income

Regular gifts from surplus income can be exempt if they form part of normal expenditure and don't reduce the standard of living of the giver.

Business Relief

Business assets can qualify for 50% or 100% relief from inheritance tax, depending on the type of asset.

Agricultural Property Relief

Farmland and farming businesses may qualify for up to 100% relief.

Inheritance Tax Planning Strategies

With careful planning, there are legitimate ways to reduce potential inheritance tax liability:

1. Make a will: This ensures your estate is distributed according to your wishes and takes advantage of available allowances.

2. Consider lifetime giving: Gifts made more than seven years before death are typically exempt from inheritance tax (known as potentially exempt transfers).

3. Use trusts: Certain types of trusts can be used to manage and potentially reduce inheritance tax liability.

4. Take out life insurance: Policies written in trust can provide funds to pay inheritance tax without increasing the value of your estate.

5. Make pension contributions: Pensions can sometimes be passed on free from inheritance tax.
