When wondering what happens to inheritance tax when you die, many people feel overwhelmed. In this guide, we’ll explore every angle: from valuation to exemptions, payment deadlines, and estate planning tips.

 

Understanding what happens to inheritance tax when you die is not just about the tax bill. It’s about protecting your legacy and ensuring your loved ones receive what you intended. Whether you’re planning your own estate or managing one after a loved one has passed, having a clear roadmap is essential.

What happens to inheritance tax when you die? – Quick summary

Here’s the short answer:

1. HMRC checks your estate’s value.
2. Your estate pays 40% on any amount above the £325,000 nil‑rate band (or £500,000 including main residence).
3. You pay within six months of death.
4. Executors handle this before distributing inheritance.

 

This process may sound simple, but there are many nuances. Estates vary in complexity, and exemptions, reliefs, and planning options can significantly alter outcomes. These details matter whether you’re dealing with property-rich estates or significant liquid assets.

 

What happens to inheritance tax when you die? – Step‑by‑step breakdown

1. Estate valuation

The first step in determining what happens to inheritance tax when you die is valuing the estate. Executors or administrators compile an inventory of assets, including:

 

• Real estate (including second homes or buy-to-let properties)
• Bank and savings accounts
• Investment portfolios and ISAs
• Premium bonds and NS&I holdings
• Life assurance policies not written in trust
• Vehicles, valuable art, jewellery, antiques, and collectibles

 

This gross value is offset by liabilities such as mortgages, personal loans, credit card debts, and funeral costs. Accurate accounting is crucial. Errors in this phase can delay probate and potentially incur HMRC penalties. Professional valuations may be required for high-value or disputed assets.

 

2. Nil‑rate band

The nil-rate band determines how much of an estate is tax-free. As of 2024/25:

• Standard nil-rate band: £325,000
• Residence nil-rate band: up to £175,000 if a home is passed to direct descendants (children, stepchildren, grandchildren)

If unused, these allowances can be transferred between spouses or civil partners, potentially allowing couples to pass on up to £1 million without incurring inheritance tax. The interaction of these thresholds is key to minimising liability.

 

3. Tax rate applied

Inheritance tax is generally charged at:

• 40% on the portion of the estate above the available allowances
• 36% if at least 10% of the estate is left to charity

Using charitable donations strategically can reduce the overall tax burden. This highlights why understanding what happens to inheritance tax when you die matters not just for heirs, but for philanthropic goals too.

 

4. Who pays?

The legal responsibility for paying IHT lies with the estate. It’s typically managed by the executor or personal representative, who must:

1. Submit the correct forms (IHT400, IHT421, etc.)
2. Ensure values are correctly documented
3. Arrange for payment from estate assets

In some cases, where IHT is payable on lifetime gifts, the recipient of the gift may bear the liability. This usually applies only if the donor dies within seven years of making a large gift. Read our blog on this topic to understand more…

 

5. Payment timeline

Payment is due within six months of the end of the month in which death occurs.

If not paid on time:

• Interest accrues daily on unpaid tax
• HMRC can impose penalties for late reporting

In certain situations—particularly where the estate includes property or shares—executors can apply to pay in annual instalments over up to 10 years. This is subject to interest but allows beneficiaries time to manage large asset sales.

Reporting and forms

6. HMRC forms

Executors must submit a variety of forms, including:

• IHT400: Used for estates over the threshold or with complexities (e.g., overseas assets, trust holdings)
• IHT205: A simplified return for smaller estates below the nil-rate band

These are submitted alongside a probate application. Mistakes in paperwork are a leading cause of probate delays.

 

7. Filling out forms

Accurate reporting includes:

• Full market values of assets at date of death
• Documentation of debts and liabilities
• Details of gifts made in the previous seven years

Supporting documentation—like bank statements, valuations, and gift receipts—can be requested by HMRC.

 

8. Seven‑year rule for gifts

Lifetime gifts made within seven years of death may be subject to IHT:

• Gifts within 0–3 years: taxed at full 40%
• 3–7 years: eligible for taper relief, reducing tax rate to as low as 8%

Certain gifts—like those out of surplus income—may be exempt, provided specific criteria are met.

Exemptions and reliefs

9. Spouse exemption

Assets passed to a UK-domiciled spouse or civil partner are 100% exempt from IHT. This also allows unused allowances to be transferred, increasing tax-efficiency across both estates.

 

10. Charity gifts

Gifts to UK-registered charities are fully exempt. Including a charitable bequest in your will not only supports causes you care about but may reduce the overall IHT rate for your estate.

 

11. Agricultural/farm relief

Qualifying agricultural property may benefit from:

• 100% relief (if owner-occupied or let under certain conditions)
• 50% relief in other qualifying cases

Farmhouses must be of a character appropriate to the land and occupied for agricultural purposes.

 

12. Business relief

Business Property Relief (BPR) can reduce IHT on certain business assets:

• 100% relief on ownership of a business or shares in an unlisted company
• 50% relief on controlling holdings in quoted companies or land used in a business

This encourages business continuity across generations.

Estate planning

13. Using trusts

Trusts can be powerful tools to manage and protect wealth:

• Discretionary trusts offer control over when and how assets are distributed
• Life interest trusts allow income for a beneficiary while preserving capital

Trust planning is complex and must be carefully structured to avoid unintended tax consequences.

 

14. Lifetime gifting

Regular gifting, if planned well, can reduce your estate’s IHT exposure:

• £3,000 annual exemption
• Gifts on marriage (up to £5,000 from parents)
• Small gifts of £250 per person

Gifting out of surplus income can also be effective, but must be regular and well-documented.

 

15. Pension planning

Pensions generally sit outside your estate for IHT purposes. Consider:

• Nominating beneficiaries for drawdown or lump sums
• Ensuring pension funds are not unintentionally drawn down prior to death

Some pensions (like final salary schemes) may have different rules, so review arrangements regularly.

Tax payment

16. Paying IHT

Executors must:

• Pay within 6 months
• Use Direct Payment Scheme from bank accounts or NS&I
• Apply for instalment plans for illiquid assets

Advance planning can help ensure sufficient liquidity in the estate.

 

17. Penalties & interest

• Interest charged at HMRC’s published rate (currently 7.75%)
• Penalties apply for late filing, underpayment, or negligence

Using professionals reduces risk of misreporting and administrative errors.

Practical examples

Example A – Smaller estate

• Total estate: £280,000
• Below nil-rate band, no tax due
• All assets passed to children

 

Example B – Married couple

• First spouse passes with unused allowances
• Second estate: £950,000 including property
• IHT on £950k – £1m = £0

 

Example C – Gifting strategy

• Individual gifts £300,000 to child, survives 5 years
• Taper relief reduces effective tax rate
• Net IHT on gift potentially reduced to 24% (vs 40%)

Checklist for executors

✅ Register the death and find the will

✅ Apply for probate (or confirmation in Scotland)

✅ Value assets and liabilities

✅ Submit IHT forms and pay tax

✅ Obtain grant and distribute estate

Keeping records of all communications, decisions, and valuations is essential throughout.
