Inheritance Tax (IHT) is one of the most misunderstood UK taxes. Many people worry that when they die, a large portion of their estate will be lost to HMRC — leaving less for their loved ones.
The reality is more reassuring: most people in the UK will never pay inheritance tax. However, understanding the rules is essential if you want to plan effectively and avoid unnecessary tax.
In this guide, we explain what inheritance tax is, how much you might pay, who is exempt, and how families can legally reduce inheritance tax liability.
What Is Inheritance Tax?
Inheritance Tax is a tax charged on a person’s estate after they die. An estate includes:
- Property (including your home)
- Savings and investments
- Personal possessions
- Business assets
- Any gifts made in the last seven years
The standard inheritance tax rate is 40%, but it only applies to the portion of your estate above the tax-free threshold.
What Is the Inheritance Tax Threshold?
For the 2025/26 tax year, the main inheritance tax allowances are:
- Nil Rate Band (NRB)
- £325,000 tax-free
- Applies to everyone
- Frozen until at least April 2028
- Residence Nil Rate Band (RNRB)
- Up to £175,000 extra
- Available when you leave your main home to children or grandchildren
- Can increase your total tax-free allowance to £500,000
Married Couples & Civil Partners
Couples can transfer unused allowances, meaning they may pass on up to:
- £1 million tax-free (£500,000 each)
How Much Inheritance Tax Will I Pay?
You may not pay any inheritance tax if:
- Your estate is worth less than £325,000
- You leave everything above £325,000 to:
- Your spouse or civil partner
- A registered charity
- You pass your home to children or grandchildren and your estate is under £500,000
Example:
If your estate is worth £525,000 and your available allowance is £325,000:
- Taxable amount: £200,000
- Inheritance tax due: £80,000 (40%)
Why Does Inheritance Tax Exist?
Inheritance tax is designed to prevent wealth being passed down indefinitely without taxation. It contributes to public finances and aims to reduce long-term wealth inequality.
However, rising property prices have meant more estates fall within the inheritance tax net — even though thresholds have remained frozen. This makes estate planning more important than ever.
What Happens If I Inherit My Parents’ Home?
If a home is left to direct descendants (children or grandchildren), the estate may benefit from both:
- £325,000 Nil Rate Band
- £175,000 Residence Nil Rate Band
This means up to £500,000 can be inherited tax-free.
Important conditions:
- The total estate must be below £2 million to qualify fully
- For estates over £2 million, the residence allowance is reduced by £1 for every £2 above the limit
- Homes held in discretionary trusts usually do not qualify for the residence allowance
Example:
Estate value: £525,000
Home left to child
- £500,000 tax-free
- £25,000 taxed at 40% = £10,000 inheritance tax
Without passing the home to a direct descendant, the tax bill would be £80,000 instead.
Inheritance Tax Rules for Married Couples
Transfers between spouses or civil partners are 100% inheritance tax-free, regardless of value.
If one partner dies without using their full allowance, the unused portion transfers to the surviving partner. This can double the available allowances.
Example:
A couple with £1 million in assets:
- First death: no tax
- Second death: up to £1 million tax-free
The executors claim this allowance from HMRC — no action is required during your lifetime.
How Can I Reduce Inheritance Tax?
While inheritance tax planning can be complex, common strategies include:
- Making use of the £3,000 annual gifting allowance
- Passing assets to a spouse or civil partner
- Leaving gifts to charities (can also reduce the tax rate to 36%)
- Using trusts (with professional advice)
- Holding wealth in pensions rather than savings
- Planning gifts early to benefit from the 7-year rule
Professional advice is essential to avoid unexpected tax consequences.
Who Pays Inheritance Tax?
Inheritance tax is paid from the estate, not usually by the beneficiaries.
The executor or administrator of the estate is responsible for:
- Valuing the estate
- Reporting to HMRC
- Paying any inheritance tax due
Beneficiaries typically receive their inheritance tax-free, although future income (such as rental income) may be taxable.

Final Thoughts
Inheritance tax only affects a minority of UK families, but poor planning can lead to unnecessary tax bills. With thresholds frozen and property values rising, understanding inheritance tax rules has never been more important.
