Inheritance Tax records for an estate

Inheritance Tax records should show how the estate's reported value and claimed treatment were established. A calculation with no supporting documents is difficult to check, especially where gifts, trusts, foreign assets or reliefs are involved.

Keep valuation and tax treatment separate

Record the date-of-death value first, with the valuation evidence. Then identify the proposed exemption, allowance or relief and the facts supporting it. Do not reduce an asset to zero in the register simply because you believe a relief will apply.

HMRC's guidance explains when an estate's value must be reported and when it may qualify as an excepted estate. ^[1] The death date matters: apply the rules relevant to that estate rather than a remembered threshold or a future reform.

Preserve evidence behind special claims

For transferable allowances, locate the earlier spouse's or civil partner's estate information. For business, agricultural or overseas assets, identify the ownership history and obtain advice on the current conditions. Record any missing documents and how the estimate was reached.

Track payments and HMRC correspondence separately from the initial liability calculation. Lifetime gift records addresses a common evidence gap; the asset register supplies the valuation foundation. If new information changes a figure, ask about the appropriate correction rather than leaving inconsistent tax and probate records.

Make the calculation reproducible Arrange the working papers so a second person can follow each figure from source to return. Give an asset a stable reference and use that reference on the valuation, correspondence and calculation. If several accounts appear on a single institution's letter, explain how their balances have been allocated. Keep gross assets and deductible liabilities visible rather than presenting only a net total. This allows an adviser to check whether an item has been counted twice, omitted or treated as deductible without a sufficient basis.

Retain the assumptions that sit behind estimates. A business valuation might depend on accounts that have not been finalised, while a property appraisal may assume a particular ownership share. Record the uncertainty and the proposed route to resolve it. A rounded number is more useful when the reader can see how it was reached and why better evidence is not yet available. When a replacement valuation arrives, preserve the earlier version and identify which tax and probate documents need reconsideration, rather than silently overwriting the original working file.

Support the estate's reporting route Ask the adviser to explain why the estate qualifies for the reporting route being used. The absence of tax payable does not, by itself, establish that no detailed account is required. Gifts, trusts and overseas connections can change what information is needed. Keep the relevant death date prominent because the rules and forms applicable to an earlier death may differ from those for a current estate. HMRC's estate valuation guidance links the valuation exercise to the decision about reporting; retain the reasoning as well as the final form. [1]

Where a claim depends on another person's estate, obtain the underlying records early. The family may remember that a surviving spouse inherited everything but be unable to locate the earlier will, grant or distribution information. Record what is missing and who may hold it. Do not substitute a relative's recollection for documents without explaining the limitation. The tax adviser can then identify which evidence is necessary for the particular allowance or relief and whether further enquiries should be made before the account is submitted.

Separate tax due at death from administration taxes Create different sections for Inheritance Tax and for tax on income or disposals during administration. A rental payment received after death is not simply another date-of-death asset value, and a later sale may require its own tax analysis. Keep the sale contract, completion statement and original valuation linked, but do not collapse them into a single unexplained figure. The estate's administration period can generate separate reporting obligations, which should remain visible in the timetable alongside the initial estate account. [2]

Maintain a payment log showing the tax reference, amount, date, source of funds and the liability the payment is intended to meet. Record direct payments by a bank so the same expense is not later charged again to the estate account. Distinguish an estimate, a payment on account and a confirmed final position. If instalment arrangements are relevant, ask what ongoing interest or later payment events need monitoring. Beneficiaries should receive an accurate account of what remains reserved without being promised that an initial payment closes every tax issue.

Respond to new information coherently When HMRC asks a question, preserve the exact enquiry and link the response to its supporting papers. Assign one coordinator to prevent co-executors sending inconsistent explanations. If a forgotten account or lifetime transfer is discovered, tell the adviser promptly and ask which correction process applies. Keep the amended calculation, submitted response and acknowledgement together, with a note of any resulting payment or refund. Before final distribution, review unresolved tax correspondence and retention needs. A tidy file should show both the figures ultimately accepted and the route by which the estate reached them.
