Being an Executor: Can You Be Personally Liable for Inheritance Tax?

• Executors are legally responsible for ensuring the correct amount of Inheritance Tax is paid.
• Personal liability arises if Estate assets are distributed before HMRC is fully settled.
• Agreements with beneficiaries do not remove Executor liability.
• Executors must verify and disclose all Estate assets and liabilities.
• Professional advice is often essential where Estates are large, complex, or illiquid.

An Executor is the individual named in a Will who is legally responsible for administering the deceased’s Estate.

The Estate includes all assets, liabilities, and income of the deceased at the date of death.

Inheritance Tax is primarily payable by the Estate. However, the Executor is personally responsible for ensuring it is calculated correctly and paid on time.

While the tax belongs to the Estate, the legal duty sits with the Executor. This is the source of personal risk.

In England and Wales, Executors owe a fiduciary duty to the Estate and its beneficiaries. This duty includes:

• Identifying all assets and liabilities
• Valuing the Estate accurately for Inheritance Tax
• Submitting a complete and correct IHT return to HMRC
• Paying Inheritance Tax before distributing assets

Executors can be personally liable for losses caused by a breach of these duties, regardless of intent.

An Executor is most at risk where:

• Assets are distributed before the full IHT bill is settled
• Estate values are understated
• Unknown assets later come to light
• Reliance is placed on beneficiary promises to pay tax

Once funds leave the Estate, HMRC can pursue the Executor personally.

A well-known High Court case involved an Executor administering a £1.2 million Estate that included land. While initial Inheritance Tax was paid, the balance was deferred. The Estate was then distributed to beneficiaries on the understanding that one beneficiary would settle the remaining tax.

That beneficiary left the UK and did not pay.

The court confirmed the Executor was personally liable for the unpaid £340,000. HMRC was entitled to pursue the Executor’s own assets.

The lesson is clear. Informal agreements do not protect Executors.

Executors must ensure the following order of payment:

1. Funeral expenses
2. Secured debts
3. Unsecured debts
4. Inheritance Tax
5. Distributions to beneficiaries

If the Estate is illiquid, Executors must follow statutory procedures before releasing any assets.

Inheritance Tax is due six months after death. Interest accrues after this point. Executors cannot sell many assets until probate is granted, but options exist:

Banks and investment managers can release funds directly to HMRC before probate in many cases.

HMRC allows instalments for certain assets, including:

• UK property
• Shares giving control of a company

Typically, 10 annual instalments apply, plus interest.

Short-term Executor loans can cover the tax until probate is granted and assets are sold. Each option carries risk and should be assessed carefully.

Many Executors assume liability transfers once assets are handed to beneficiaries. It does not.

The Executor remains responsible until HMRC is fully paid. This is where professional guidance is critical, particularly for Estates involving property, businesses, or overseas assets.

Before distributing any assets, confirm:

• Full asset searches are completed
• All liabilities are identified
• IHT calculations are reviewed professionally
• HMRC payments are confirmed in writing
• Estate reserves are retained for contingencies

• Relying on beneficiary promises
• Distributing assets early
• Estimating values without evidence
• Ignoring overseas or historic assets
• Acting without advice on complex Estates

Acting as an Executor is a serious legal responsibility, not an honorary role. Personal liability for Inheritance Tax is real and enforceable. Where Estates are significant or complex, professional advice is not optional, it is protective.

If the responsibility feels disproportionate, you are entitled to renounce the role before acting.
