What is Inheritance Tax?
Inheritance Tax (IHT) is a tax paid on the estate (money, property, and possessions) of someone who has passed away.
In the UK, it is managed by HMRC and usually applies when the estate value exceeds certain thresholds.
Current Inheritance Tax Thresholds
In most cases, Inheritance Tax is charged at:
- 40% on estates above the threshold
- A tax-free allowance known as the Nil Rate Band (typically £325,000)
- An additional Residence Nil Rate Band may apply when passing on a home to direct descendants
These allowances can significantly reduce the tax due.

How Inheritance Tax is Calculated

- Investments
- Personal belongings

You may qualify for:
- Nil Rate Band (£325,000)
- Residence Nil Rate Band (if applicable)
- Transfers between spouses (usually tax-free)
3. Apply the Tax Rate
Anything above the allowance is usually taxed at:
- 40% standard rate
- Reduced rates may apply if part of the estate is left to charity
Example Calculation
For example:
- Estate value = £600,000
- Allowance = £325,000
Taxable amount = £275,000
Inheritance Tax = £275,000 × 40% = £110,000
