How to Calculate Inheritance Tax: Complete UK Guide (2024)

Inheritance Tax (IHT) is a tax on the estate (property, money, and possessions) of someone who has died. Understanding how to calculate inheritance tax is crucial for effective estate planning and ensuring your beneficiaries receive as much as possible of your hard-earned assets.

What is Inheritance Tax?

Inheritance Tax is levied at 40% on estates valued above certain thresholds. The current thresholds for 2024/25 are:

• Nil-rate band: £325,000 (frozen until April 2028)
• Residence nil-rate band: £175,000 (when leaving a home to direct descendants)
• Total possible allowance: £500,000 per person (£1 million for couples)

Who Pays Inheritance Tax?

Not all estates are subject to IHT. You typically don’t pay Inheritance Tax if:

• The estate value is below the £325,000 threshold
• Everything above the threshold is left to a spouse, civil partner, charity, or community amateur sports club
• The estate qualifies for 100% Agricultural or Business Property Relief

Step-by-Step Inheritance Tax Calculation

1. Value the estate: Add up all assets (property, investments, possessions) and subtract any debts
2. Apply exemptions: Subtract the nil-rate band (£325,000) and any available residence nil-rate band (£175,000)
3. Calculate taxable amount: Any value above the total allowance is taxable at 40%
4. Consider reliefs: Apply any available reliefs (business, agricultural, or charitable donations)
5. Account for gifts: Add back any gifts made in the 7 years before death (tapering relief may apply)

Inheritance Tax Thresholds and Allowances

Allowance Type	2023/24 Amount	2024/25 Amount	Notes
Standard Nil-Rate Band	£325,000	£325,000	Frozen until April 2028
Residence Nil-Rate Band	£175,000	£175,000	Only applies when leaving a home to direct descendants
Annual Gift Exemption	£3,000	£3,000	Per tax year, can be carried forward one year
Small Gifts Exemption	£250	£250	Per recipient, unlimited number

Inheritance Tax Rates and Reliefs

The standard Inheritance Tax rate is 40%, but there are several important reliefs:

• Spouse/Civil Partner Exemption: 100% exemption for transfers between UK-domiciled spouses
• Charity Exemption: Gifts to qualifying charities are 100% exempt
• Business Property Relief: 50% or 100% relief on business assets
• Agricultural Property Relief: 50% or 100% relief on agricultural land
• Tapering Relief: Reduces tax on gifts made 3-7 years before death

Inheritance Tax on Gifts

Gifts made in the 7 years before death may be subject to Inheritance Tax, with tapering relief applying after 3 years:

Years Before Death	Tax Reduction	Effective Tax Rate
0-3 years	0%	40%
3-4 years	20%	32%
4-5 years	40%	24%
5-6 years	60%	16%
6-7 years	80%	8%

How to Reduce Inheritance Tax

Legal strategies to minimize IHT liability include:

• Making gifts: Utilize annual exemptions and small gift allowances
• Setting up trusts: Certain trusts can remove assets from your estate
• Life insurance: Policies written in trust can cover IHT bills
• Business relief: Invest in qualifying business assets
• Charitable giving: Reduces IHT rate to 36% if 10%+ of estate left to charity
• Equity release: Can reduce estate value while providing funds

Common Inheritance Tax Mistakes

Avoid these pitfalls when planning for IHT:

1. Assuming your estate is below the threshold without proper valuation
2. Forgetting about the 7-year rule for gifts
3. Not considering the residence nil-rate band requirements
4. Overlooking life insurance policies that may be part of the estate
5. Failing to keep proper records of gifts and exemptions
6. Not reviewing your will regularly for tax efficiency

Inheritance Tax for Non-Domiciled Individuals

For non-UK domiciled individuals, IHT rules differ:

• Only UK assets are subject to IHT (not worldwide assets)
• Spouse exemption is limited to £325,000 unless spouse is UK-domiciled
• Different rules apply for “deemed domiciled” status after 15+ years in UK
• Special rules for excluded property trusts

When to Seek Professional Advice

Consider consulting a tax specialist if:

• Your estate exceeds £1 million
• You own business or agricultural assets
• You have complex family situations (second marriages, stepchildren)
• You’re non-UK domiciled with UK assets
• You want to set up trusts or use sophisticated planning strategies

Frequently Asked Questions

What is the 7-year rule for inheritance tax?

The 7-year rule states that gifts made more than 7 years before death are generally exempt from Inheritance Tax. Gifts made within 7 years may be taxable, with tapering relief applying after 3 years.

Can I give away my home to avoid inheritance tax?

Giving away your home may still be subject to IHT if you continue to benefit from it (gift with reservation rules). The residence nil-rate band provides better tax relief when leaving your home to direct descendants.

How does inheritance tax work for married couples?

Married couples and civil partners can transfer unused nil-rate bands between them, potentially doubling their allowance to £1 million (£650,000 standard + £350,000 residence).

What happens if I don’t pay inheritance tax?

HMRC will pursue unpaid IHT with interest and potential penalties. The executors of the estate are personally liable for ensuring IHT is paid before distributing assets to beneficiaries.

Are funeral expenses deductible for inheritance tax?

Yes, reasonable funeral expenses can be deducted from the estate value before calculating Inheritance Tax, along with other administration costs and debts.
