Paying Inheritance Tax when an estate is tied up in assets

Inheritance Tax can create a timing problem: an estate may contain enough value to meet the bill, while the people administering it cannot yet access sufficient cash. The practical task is to connect the payment timetable with the funds that can actually be released.

This guide explains that funding question. It does not calculate an estate's tax liability or decide which payment arrangement is available. Probate and related procedures differ across the UK, so establish the process that applies to the estate concerned.

Confirm the amount, deadline and payment reference

GOV.UK's payment guidance states the usual deadline as the end of the sixth month after death and explains that a payment towards tax is normally needed before the grant. Interest can arise if payment is late.

For example, under that ordinary deadline, a death in February points to the end of August. That is a calendar illustration, not a substitute for checking the estate's actual obligations or any applicable instalment arrangements.

Record who is calculating the tax, which figures remain estimated and who obtains the payment reference. The person arranging funds needs a usable schedule, not merely an assurance that the tax adviser is dealing with everything.

Distinguish estate value from available payment sources

List assets with a separate column showing whether money can be released for tax and what the institution requires. A house, investment account and bank deposit may have similar stated values but very different practical routes to payment.

An illustrative estate might have a £500,000 property, £30,000 in bank accounts and an £80,000 investment portfolio. If the provisional tax payment needed is £65,000, the bank balance alone leaves £35,000 to find. This does not calculate the tax on those assets; it assumes an independently established provisional bill purely to demonstrate the funding gap.

Do not assume that a property sale will complete before the deadline. Record the expected sale timing as uncertain until the relevant professionals can confirm the position.

Ask institutions about direct payment to HMRC

GOV.UK describes the Direct Payment Scheme, through which participating banks, savings institutions and investment providers can pay HMRC from the deceased person's accounts before probate or confirmation. Each institution has its own requirements and not every provider participates.

Ask about the process, available amount, documents and expected timescale. Where investment assets are involved, establish whether sales are needed, who authorises them and how transaction costs or changing values affect the available cash.

Using an account to pay HMRC directly is different from releasing its entire balance to an executor for unrestricted use. Make that distinction clear when discussing the arrangement with beneficiaries or recording expected receipts.

Compare other funding routes by their total consequences

If accessible estate funds are insufficient, obtain advice about the alternatives relevant to the estate. These can involve eligible instalment arrangements, a request to postpone payment in qualifying circumstances or external finance. Their availability and cost should be confirmed rather than assumed.

Where a family member proposes using personal money, document the arrangement and obtain advice about repayment from the estate. Consider the effect on that person's own emergency funds and commitments. A large estate valuation does not guarantee prompt reimbursement.

For any borrowing proposal, ask for interest, arrangement fees, security, repayment events and the consequences of delay. Compare the total likely cost under more than one timetable, including a slower property sale. Do not focus only on whether the first payment can be made.

Allow for uncertainty in the tax calculation

Valuations or other information may still be provisional as the payment date approaches. The payment guidance explains that payments on account can be made before the final amount is known. Ask the tax adviser how the proposed amount was reached and what subsequent adjustment may be needed.

Keep the estimate version and date alongside each funding decision. If the expected bill changes, update the funding schedule rather than leaving different people working from different totals.

For the illustrative £65,000 payment above, a later revised requirement of £72,000 adds £7,000 to the amount needed. A plan that uses every available pound for the first estimate has no room for that change or for unrelated administration costs.

Coordinate payment evidence and the next procedural step

Keep confirmation of payment instructions, the reference used and evidence that money left the relevant account. Establish who checks receipt and follows up if the expected next step does not happen.

Avoid asking beneficiaries to treat a tax payment as confirmation that the estate is ready for distribution. Other liabilities, administration work or legal issues may remain. GOV.UK's estate distribution guidance explains the need to retain enough for outstanding debts and tax.

A shared status record can identify the calculation owner, payment source, instructions sent, receipt evidence and outstanding action. This is particularly useful when a solicitor, accountant, bank and several personal representatives are involved.

What to bring to a funding discussion

Bring the provisional tax calculation, date of death, asset schedule, institution responses and likely sale timetable. Ask the professional adviser to distinguish confirmed access from assumptions and identify the point at which a backup arrangement needs to be pursued.

The aim is to avoid discovering a funding gap on the payment deadline. A good plan connects each obligation with an identified source of money and a realistic release process, while making the cost of delays visible.
