Understanding the inheritance tax threshold is an important part of estate planning in the UK. The threshold determines how much of an estate can be passed on to beneficiaries before Inheritance Tax (IHT) becomes payable.
For the 2026/27 tax year, the standard inheritance tax threshold UK allowance is £325,000 per individual, known as the Nil Rate Band (NRB). Any value above this amount may be subject to Inheritance Tax at 40%, depending on available exemptions, reliefs, and allowances.
Many people ask, “What is the inheritance tax threshold?” The answer depends on factors such as whether a home is passed to direct descendants, whether unused allowances can be transferred from a spouse or civil partner, and the total value of the estate.
Understanding these rules can help families make informed decisions about estate planning and reduce potential tax liabilities.
What Is the Inheritance Tax Threshold?
The inheritance tax threshold is the maximum amount an individual can leave behind before their estate becomes liable for Inheritance Tax.
In the UK, the main inheritance tax limit is made up of two key allowances:
- Nil Rate Band (NRB)
- Residence Nil Rate Band (RNRB)
These allowances determine how much of an estate can be inherited tax-free.
The value of an estate includes assets such as:
- Property and residential homes
- Savings and investments
- Shares and securities
- Business interests
- Personal possessions
- Other valuable assets
If the taxable estate exceeds the available inheritance tax allowances, the excess amount is generally taxed at 40%.
What Is the Current Inheritance Tax Threshold in the UK?
The current inheritance tax threshold UK consists of the following allowances:
| Allowance | Amount | Who Can Use It? |
|---|---|---|
| Nil Rate Band (NRB) | £325,000 | Available to every individual |
| Residence Nil Rate Band (RNRB) | £175,000 | Available when a qualifying home passes to direct descendants |
| Maximum individual allowance | Up to £500,000 | When both allowances apply |
The standard inheritance tax limit remains £325,000. However, individuals who qualify for the Residence Nil Rate Band may increase their tax-free allowance to £500,000.
For example:
- A person leaving their home to children may benefit from the additional £175,000 residence allowance.
- A person without a qualifying residence transfer may only benefit from the £325,000 Nil Rate Band.
How Does the Nil Rate Band Work?
The Nil Rate Band (NRB) is the basic inheritance tax allowance available to every individual.
An estate valued up to £325,000 will normally have no inheritance tax liability. If the estate exceeds this amount, the portion above the threshold may be charged at the standard IHT rate of 40%.
For example:
- Estate value: £500,000
- Nil Rate Band: £325,000
- Taxable amount: £175,000
- Potential IHT at 40%: £70,000
However, available exemptions and reliefs may reduce the final inheritance tax bill.
What Is the Residence Nil Rate Band?
The Residence Nil Rate Band (RNRB) provides an additional inheritance tax allowance when someone leaves their main residence to direct descendants.
Direct descendants include:
- Children
- Grandchildren
- Adopted children
- Stepchildren
- Foster children in certain circumstances
The current Residence Nil Rate Band is £175,000 per person.
When combined with the standard Nil Rate Band:
- £325,000 Nil Rate Band
- £175,000 Residence Nil Rate Band
An individual may have a total inheritance tax threshold of up to £500,000.
A married couple or civil partners may potentially combine their allowances and pass on up to £1 million tax-free, provided they meet the qualifying conditions.
How Does the Inheritance Tax Threshold Work for Married Couples?
Married couples and civil partners have additional inheritance tax planning opportunities because unused allowances can usually be transferred to the surviving partner.
For example:
- One spouse leaves their entire allowance unused.
- The surviving spouse can claim the unused percentage when they die.
This means a couple may potentially benefit from:
- £650,000 combined Nil Rate Band (£325,000 × 2)
- £350,000 combined Residence Nil Rate Band (£175,000 × 2)
Giving a possible total inheritance tax allowance of £1 million.
The exact amount depends on individual circumstances and whether the qualifying conditions are met.
What Happens to Large Estates? Understanding Tapering Rules?
The Residence Nil Rate Band is subject to tapering for larger estates.
If an estate is worth more than £2 million, the Residence Nil Rate Band may be reduced.
The reduction works as follows:
- The RNRB reduces by £1 for every £2 that the estate exceeds £2 million.
- For very high-value estates, the Residence Nil Rate Band may be completely removed.
The standard Nil Rate Band of £325,000 is not affected by tapering.
This makes estate valuation an important part of inheritance tax planning, particularly for individuals with significant property or investment assets.
How Do Gifts Affect the Inheritance Tax Threshold?
Lifetime gifts can affect the inheritance tax threshold because certain gifts may be included when calculating the value of an estate.
The seven-year rule is one of the most important inheritance tax rules.
If an individual survives for seven years after making a gift, the gift normally falls outside their estate for IHT purposes.
Gifts made within seven years before death may be considered Potentially Exempt Transfers (PETs) and could become liable for inheritance tax.
Common inheritance tax gift allowances include:
- Annual exemption of £3,000 per tax year
- Small gifts allowance of £250 per recipient
- Wedding or civil ceremony gifts within permitted limits
Careful planning around gifting can help reduce the value of an estate over time.
What Inheritance Tax Reliefs and Exemptions Are Available?
Several exemptions and reliefs may reduce inheritance tax liability.
Spouse or Civil Partner Exemption
Assets left to a spouse or civil partner are normally exempt from inheritance tax.
Unused allowances can also usually transfer to the surviving spouse or civil partner.
Charity Exemption
Gifts left to registered charities are exempt from inheritance tax.
If at least 10% of an estate is left to charity, the inheritance tax rate on the remaining estate may reduce from 40% to 36%.
Business Property Relief (BPR)
Business Property Relief may reduce or remove inheritance tax on qualifying business assets.
This can apply to certain:
- Trading businesses
- Shares in qualifying companies
- Business interests
Agricultural Property Relief (APR)
Agricultural Property Relief may apply to qualifying agricultural land and property.
Eligibility depends on ownership, occupation, and the type of agricultural asset.
How Can You Reduce an Inheritance Tax Bill?
Effective estate planning can help families make better use of available inheritance tax allowances.
Useful planning steps include:
- Review your estate value regularly.
- Make use of available gifting allowances.
- Consider whether your home qualifies for the Residence Nil Rate Band.
- Keep records of unused allowances from a deceased spouse or civil partner.
- Explore trusts where appropriate.
- Consider professional inheritance tax advice for complex estates.
Inheritance tax planning should be reviewed regularly because tax rules and personal circumstances can change.
