Valuing a house for probate: what it costs and what HMRC expects

The property is normally the largest number on the account, and the one HMRC is most likely to question. Getting the basis right costs very little and avoids an enquiry later.

The two routes

RICS 'red book' valuation for probate£250 – £700Formal opinion, defensible on enquiry

What HMRC wants is open market value at the date of death: the price the property would fetch between a willing buyer and a willing seller on that day. An asking price is not a valuation.

When to pay for a RICS valuation

  • Inheritance Tax is payable, so the figure directly changes the bill
  • The estate is near a threshold and the property could tip it over
  • The property is unusual: a farm, a conversion, land with development potential, or in poor repair
  • A beneficiary is buying out the others, so the figure decides who gets what
  • Beneficiaries do not all agree on the value

Undervaluing is not a saving

If the property later sells for far more, HMRC can revisit the account, charge additional tax and consider a penalty. Where the sale happens soon after death, the sale price is strong evidence of the date-of-death value.

If the property sells for less

Where a qualifying sale within four years of death is at a lower price, loss on sale relief may allow the sale price to replace the probate value for Inheritance Tax, on form IHT38. It only helps where tax was actually paid.

Common questions

Can I use the Land Registry sold price?
Only as supporting evidence. Comparable sales help justify a figure, but HMRC expects a valuation of the actual property in its actual condition at the date of death.
