How to Value an Estate for Probate: What HMRC Actually Wants
Short answer
HMRC expects executors to report open-market values at the date of death — not insurance replacement costs. Getting valuations wrong can delay probate, trigger penalties, or result in unnecessary inheritance tax. This guide explains what HMRC commonly expects for major asset types in England and Wales.
The valuation standard HMRC applies
For inheritance tax purposes, assets in the estate are valued at their open-market value on the date of death. Open-market value means the price the asset might reasonably fetch if sold on that date between a willing buyer and a willing seller, with both having reasonable knowledge of relevant facts.
This standard applies whether or not inheritance tax is ultimately payable. Even excepted estates completing form IHT205 require accurate figures. HMRC can query valuations after the grant is issued, and under-valuation can lead to penalties and interest on additional tax.
Executors report gross assets, then deduct allowable liabilities and funeral expenses to arrive at the net estate. The valuation exercise feeds directly into which inheritance tax form is required and how quickly HMRC issues the reference needed for probate.
Insurance value vs market value: the distinction that catches families out
Insurance figures and probate values measure different things. Buildings insurance reflects rebuild or reinstatement cost — what it would cost to reconstruct the property — not what someone would pay to buy it. A home insured for £400,000 rebuild might sell for £550,000 or £350,000 on the open market. HMRC wants the sale price, not the insurance schedule.
The same principle applies to contents insurance. Replacement-cost cover for jewellery, art, or antiques often exceeds what items would fetch at auction or second-hand sale. Executors should value household contents at realistic disposal prices unless professional appraisal supports a higher figure.
Car insurance write-off or market values may be closer to open-market figures but should still be checked against date-of-death trade guides. Using the highest number available — often the insurance document left in a drawer — is a common error that inflates the estate unnecessarily or invites HMRC challenge if later contradicted.
Valuing property for probate
Residential property is frequently the largest estate asset. HMRC accepts a written valuation from a local estate agent for many straightforward cases. Where property is unusual, let, subject to agricultural or business relief, or very high value, a surveyor's Red Book valuation may be more appropriate.
The valuation date is the date of death, not the date of the agent's letter months later — though agents commonly assess retrospectively based on market conditions at death. If the market moves significantly between death and sale, later sale price can inform whether the original figure was reasonable; large discrepancies may attract HMRC attention.
Executors with property held as tenants in common value only the deceased's share. Joint tenant property passes outside the estate and is usually excluded from the deceased's probate valuation, though it may still affect inheritance tax calculations in some circumstances.
Shares, investments, and cash
Listed shares and unit trusts are valued at the closing price on the stock exchange on the date of death — or the last trading day before if markets were closed. Executors obtain prices from published tables or broker statements. Unlisted shares require more complex valuation, often needing accountant or specialist input.
Bank and building society accounts are valued at the balance on the date of death, including accrued interest to that date. National Savings products, premium bonds, and ISAs follow institution statements. Foreign currency holdings are converted using HMRC's published exchange rates for the death date.
Debts owed to the deceased are assets and should be included if recoverable. Debts owed by the deceased are liabilities deducted from the gross estate, provided they are properly evidenced and legally enforceable.
Household contents, vehicles, and personal possessions
There is no requirement to itemise every teaspoon in smaller estates. HMRC expects a realistic overall figure for general household contents unless specific high-value items are separately gifted in the will or exceed trivial limits. Room-by-room estimates of second-hand value are commonly used.
Specific legacies of valuable items — jewellery, art, collections — should be valued individually if worth more than a few hundred pounds. Professional valuation may be worthwhile for items where guesswork would be clearly unreliable.
Vehicles are typically valued using trade guides for the date of death, adjusted for condition and mileage. Keep a printout or screenshot of the guide used in case HMRC queries the figure later.
Gifts, trusts, and assets outside the will
Probate valuation is not limited to assets passing under the will. Lifetime gifts within seven years of death may affect inheritance tax and require disclosure. Assets held in certain trusts may need separate treatment. Property nominally "given away" but still occupied by the deceased can remain part of the estate for tax purposes.
Pension pots and life policies paid to named beneficiaries may fall outside the estate for probate but still affect inheritance tax depending on structure and timing. Executors should gather full details rather than assuming such assets are irrelevant.
Where valuation is genuinely uncertain, HMRC offers a post-transaction valuation check service in some cases before returns are finalised. Professional advice on borderline assets is often cheaper than correcting errors after distribution.
Getting valuations right the first time
Accurate valuations speed probate because HMRC can issue references without prolonged query. They protect executors from personal liability for under-paid tax. They also prevent beneficiaries receiving distributions based on wrong figures.
Executors should keep evidence: agent letters, share price printouts, vehicle guide pages, and notes on how contents figures were estimated. If a professional valuer is instructed for one asset class, their report should be retained with the estate papers.
Structured preparation — listing assets, noting which need professional input, and separating insurance documents from market evidence — reduces rework. The KinClarity Probate Readiness Assessment helps organise this picture; it does not provide valuations or tax advice.
