Estate Administration Expenses Deductible from IHT: What Can Be Claimed?
Not all estate costs reduce the IHT bill — but funeral expenses, debts, and reasonable professional fees do. Knowing what HMRC allows can meaningfully reduce the taxable estate.

The Key HMRC Rules
Liabilities must exist at the date of death
Only liabilities that were enforceable at the moment of death are deductible. A bill that arrives after death but relates to services received before death counts. A liability created by the estate after death (e.g. the executor's own solicitor fees) is treated as an administration expense, not a pre-death liability — deductible only if 'reasonable' and necessarily incurred in the administration.
Funeral expenses: 'reasonable' is the test
Section 172 IHTA 1984 allows 'reasonable' funeral expenses. HMRC guidance (IHTM17001) does not set a fixed cap but does scrutinise claims that seem high relative to the estate. Claims under £8,000–£10,000 are rarely challenged. Costs for multiple events, elaborate memorials, or expenses unconnected to the funeral itself are likely to be challenged.
Anti-avoidance: debts to connected persons
Under sections 162–175 IHTA 1984, HMRC can disallow liabilities that were created not in arms-length commercial dealings but to artificially reduce the estate. Common targets: loans from family members without paperwork or interest, loans that were outstanding for many years without repayment, and schemes where the deceased gave away money and then borrowed it back.
Foreign expenses on foreign assets
Costs incurred in dealing with foreign assets (overseas solicitor fees, foreign probate costs) are deductible — but only against the value of the foreign property they relate to, not against the UK estate value.
Frequently Asked Questions
What are estate administration expenses and why do they matter for IHT?
Estate administration expenses are the costs incurred in dealing with a deceased person's estate after death. They matter for IHT because deductible expenses reduce the net value of the estate on which IHT is calculated. Under section 172 IHTA 1984, funeral expenses are explicitly deductible. Under section 5 IHTA 1984, liabilities of the deceased at the date of death are deductible. Administration expenses (solicitor fees, probate fees, asset-collection costs) incurred after death are treated differently — HMRC allows some, disallows others, and caps certain categories.
Are funeral expenses deductible from IHT?
Yes. Funeral expenses are specifically deductible under section 172 IHTA 1984. HMRC allows a deduction for 'reasonable funeral expenses' including: the funeral director's fees, burial or cremation fees, the cost of a headstone or gravestone (within reason), flowers for the funeral, the cost of a wake or reception (reasonable amount), and travel expenses of the person arranging the funeral. HMRC does not allow deductions for: the cost of a memorial event held months later, excessive floral displays, or expenses that go beyond what is reasonable. A deduction of up to around £5,000–£8,000 would typically be accepted without query; very high funeral costs (e.g. £25,000+) may attract HMRC scrutiny and require justification.
Are solicitor and professional fees deductible from IHT?
Solicitor and other professional fees incurred in administering the estate are generally deductible — but with important limitations. The key rules are: (1) Only fees for work related to the UK estate are deductible — overseas professional fees for dealing with foreign assets in the IHT computation are deductible against the foreign property value; (2) HMRC's longstanding practice is to allow a deduction for 'reasonable' professional fees — if fees seem disproportionate to the estate size or complexity, HMRC may query them; (3) Fees for work that was not strictly necessary for administration may be disallowed; (4) The HMRC guidance (IHTM28011 et seq.) confirms that the costs of obtaining probate, valuing assets, and collecting assets are deductible. However: fees for financial advice, investment management, or estate planning post-death are NOT deductible. The cost of a dispute or litigation is generally NOT deductible (it is not a necessary administration cost). Cost of preparing IHT forms themselves: deductible.
What debts and liabilities are deductible from IHT?
Liabilities of the deceased at the date of death are deductible under section 5 IHTA 1984, provided they were enforceable obligations at that date. Deductible liabilities include: outstanding mortgage balances, credit card and personal loan balances, unpaid utility bills (electricity, gas, phone, council tax), income tax and capital gains tax owed to HMRC for periods up to and including the date of death (but not for the administration period), hire purchase and finance agreements, and professional fees already invoiced before death. Not deductible: debts the deceased owed to family members that were created without genuine consideration (HMRC scrutinises these under ss.162-175 IHTA 1984 anti-avoidance rules); contingent liabilities that had not crystallised at the date of death; liabilities that exceed the value of the asset they are secured against (secured on foreign property).
How do I claim deductible expenses on the IHT forms?
Deductible expenses are claimed on form IHT400 and its schedules. Key forms: (1) Funeral expenses: declared on IHT400 directly (Box 84); (2) Debts owed by the deceased to UK creditors: form IHT419 (debts owed to individuals) and the main IHT400; (3) Mortgages and loans secured on UK property: form IHT404 (jointly owned assets) or IHT405 (houses, land and buildings); (4) Administration expenses (solicitor fees, probate fees): Box 85 of IHT400. You should keep receipts and invoices for all deductible expenses — HMRC can request evidence. If you are submitting an excepted estate declaration (not IHT400), deductible expenses reduce the gross estate figure to determine whether the estate is below the excepted threshold.
