In short

As an executor, you – not the estate – can be held personally responsible for inheritance tax if it is not paid, or if you hand out money too early. HMRC charges interest from the day after the deadline. If the property is the main asset and you need to sell, speed protects you.

Being named as an executor is an honour, and it is a legal responsibility. We speak to many executors who are already grieving, already juggling work and family, and who then discover that the tax bill can land on them personally. This guide explains it in plain English.

What “personal liability” means for an executor

Inheritance tax is a debt of the estate, but HMRC can look to the executor to settle it. If you pay out to beneficiaries before the tax is dealt with and the estate then cannot cover the bill, you may be asked to answer for the shortfall personally, up to the value of the estate assets you controlled.

This is why solicitors urge executors not to distribute early, however much families want to move on. Holding back is not unkindness. It is protection.

The deadlines that matter

Interest starts the day after the deadline

At the time of writing, HMRC’s late payment interest rate on inheritance tax is 7.75% a year (in force from 9 January 2026; rates can change, so check GOV.UK for the current figure).

On a £100,000 tax bill, that works out at roughly £21 a day, or about £7,750 over a full year. That is money that comes out of what the family inherits.

The problem when the main asset is a house

Many estates are “asset rich, cash poor”. The family home is worth hundreds of thousands, but the bank accounts cannot cover the tax. Executors may be waiting on a probate grant, then on a sale, while the interest clock keeps ticking.

Options include paying from estate bank accounts via the Direct Payment Scheme, paying in instalments on certain assets such as land and property (over ten years, although selling the property brings the remaining instalments due), or selling the property. Selling is often the cleanest solution, but only if it can be done in a realistic timeframe.

Why a standard sale can be slow

A traditional estate agent sale depends on a buyer’s mortgage, a chain and a survey, any of which can slip. Recent industry figures put the time from listing to completion at around 214 days. That is well past the six-month tax deadline.

How a quick cash sale can help

A cash buyer does not need a mortgage, so there is no lender down-valuation and no chain. Exchange can often happen in as little as 7 days once you have the legal right to sell, with completion on a timeline to suit you. That lets you:

Cash buyers typically pay below full market value, and that is the trade-off for speed and certainty. It is worth comparing it honestly with the cost of waiting – the interest, bills and risk of liability.

If the property sells for less than the probate valuation

If you sell land or property within four years of death for less than the probate valuation, you may be able to claim loss-on-sale relief and reclaim some of the inheritance tax. Speak to a solicitor before you accept any offer.

Frequently asked questions

Can I be personally liable for inheritance tax as an executor?

Yes. If you distribute assets before the tax is paid and the estate cannot cover it, you may be responsible for the shortfall, up to the value of the assets you controlled.

What interest does HMRC charge on late inheritance tax?

At the time of writing, 7.75% a year (in force from 9 January 2026). Rates can change, so check GOV.UK for the current figure.

Do I have to pay inheritance tax before probate?

Usually the tax is due before the grant is issued, though you may be able to pay from the deceased’s accounts through the Direct Payment Scheme.

Can I sell the house to pay the tax?

Yes, once you have the legal authority to sell. A cash sale can exchange contracts in as little as 7 days.
