We share clear, practical examples to help UK families deal with common pitfalls in inheritance tax (IHT) and estate planning. Our aim is simple: show where real disputes and everyday administration create the biggest tax exposure — and what to do next.
We support trustees and executors by phone and email across the UK and overseas. Our team uses real scenarios — from mixed ownership property to nil rate band (NRB) arrangements — to explain risk and the actions needed to address it.
Expect practical guidance for homeowners and families, not abstract theory. We explain how value, control and benefit can affect IHT exposure. Small, everyday actions often trigger large liabilities: who paid the bills, who lived where, who used the bank account. With the NRB frozen at £325,000 since 6 April 2009 — and confirmed frozen until at least April 2031 — while the average home in England is now worth around £290,000, more ordinary families than ever find themselves caught by IHT at 40%.
For a detailed worked example, see our practical guide here: IHT case study and guide. Read on for planning lessons on record-keeping, reporting and making sure behaviour matches legal form.
Key Takeaways
- Real-life examples show how routine actions can create inheritance tax risk — even when a trust deed appears sound.
- Focus on value, control and who benefits when assessing IHT exposure.
- Keep clear records and make sure day-to-day behaviour matches the legal arrangement.
- Mixed ownership of property often causes the biggest disputes with HMRC.
- Specialist trust and estate planning advice, taken early, is the most cost-effective way to protect your family’s wealth.
Why HMRC scrutiny matters for trusts and estates in the UK
A few missed forms or unclear records can turn an ordinary estate into a full-blown IHT problem. Small reporting slips often trigger HMRC questions about value, who controlled assets and whether gifts were genuine. With IHT receipts rising year on year — driven largely by frozen allowances and rising property values — HMRC is paying closer attention to trust and estate returns than at any point in recent memory.
We see common failings that trip up trustees and executors time and again.
- Missing paperwork or late filing of trust tax returns (SA900) and IHT forms that leave gaps in the timeline.
- Unclear beneficial ownership or informal use of trust funds — particularly bank accounts where the settlor continues to make personal payments.
- Relying on a trust deed alone rather than matching everyday behaviour to the stated purposes of the trust.
HMRC looks at facts, not intentions. Inspectors review what happened in real life — who used the assets, who benefited, and whether value was effectively transferred. Under the gift with reservation of benefit (GROB) rules, they can look back at the entire period the deceased continued to benefit from a disposed asset — there is no time limit. For potentially exempt transfers (PETs), the seven-year window before death is critical.
Practical help from a specialist trust adviser usually means checking filings, reconstructing records and correcting returns early. That reduces the chance of a prolonged dispute and protects the family from unexpected IHT bills.
When planning becomes a dispute
Planning crosses into challenge territory when benefits are enjoyed informally or actions drift from the declared purposes of the trust. That is when IHT exposure rises and HMRC enquiries follow. A trust is a legal arrangement — not a magic shield. The trustees are the legal owners and must act accordingly.
Quick risk checklist
- Can you find the trust deed, bank records and dated correspondence for every key decision?
- Who paid the household bills and who lived in the property — and can you prove it?
- Are beneficiary entitlements clearly recorded and consistently acted on by the trustees?
- Has a specialist trust adviser reviewed the position recently in light of current HMRC practice?
If you spot gaps, seek early advice. As Mike Pugh says, “Plan, don’t panic.” For a practical note on structuring and debt planning, see our guide on inheritance tax structuring and debt planning.
HMRC trust and estates case studies: lessons from real clients and real disputes
Our format turns complex family events into four clear steps: facts, risks, outcome and the practical fix.
How to read each example
We start with the facts as HMRC and the tribunal saw them. Then we list the risk points plainly. Next we show what happened in the tax outcome. Finally, we give a short, practical fix you can apply straight away — because the same patterns repeat across almost every disputed estate.
What to look for in every case
Separate emotion from analysis. Families have stories. The job of HMRC — and the First-tier Tribunal — is to see how behaviour and paperwork line up with the declared purposes of the trust arrangement.
- Property used by the wrong person (typically the settlor who should have been excluded from benefit) often creates the biggest IHT exposure.
- Trust deeds that do not match reality invite HMRC challenge — and tribunals consistently side with HMRC in these situations.
- Gaps between intention and action are a recurring theme: the settlor intended to give away the asset, but their day-to-day behaviour told a different story.
Timing, purpose and the examiner’s view
Time matters. Activity in the years before death can pull earlier transfers back into a tax charge. Under the seven-year rule for PETs, gifts to individuals that fail the survival test use up the NRB first, with any excess taxed at 40%. Taper relief reduces the tax (not the value) only where gifts exceed the £325,000 NRB — and only after three years. Note that PETs only apply to outright gifts to individuals; transfers into discretionary trusts are chargeable lifetime transfers (CLTs) and are taxed under a different regime entirely.
Purpose is not decorative. Trustees must act for the stated aims of the trust and keep records to prove it. Dated trustee minutes, bank statements showing clean separation of funds, and formal letters of wishes are the evidence base HMRC expects to see. That simple discipline — matching behaviour to the trust deed — reduces the chance of a lengthy and expensive dispute.
Case study: an estate and a trust holding the same property across the years
A property held partly in personal name and partly within a trust arrangement creates practical and fiscal uncertainty. This was Graham’s situation after his mother died. Her will left the home partly outright and partly within a continuing trust arrangement. Over time, each part was treated differently in practice — and that created real problems when the family came to sell.
Why this becomes a problem. Mixed ownership often surfaces when families refinance, rent or agree a sale. Mortgage lenders, buyers and the Land Registry ask for clear title, historic valuations and proof of who benefited and when. Where legal and beneficial ownership are split — which is the very foundation of English trust law, developed over 800 years — it is essential to document the split clearly and consistently.
Key risks
- Getting the value right at relevant dates — date of death, date of any earlier transfer into trust, and any 10-year anniversary for discretionary trusts under the relevant property regime.
- Identifying lawful beneficiaries and who actually received income or enjoyed the use of the property.
- Proving what trustees actually did versus what the trust deed says — HMRC looks at behaviour, not just documents.
- Timing: missing records turn the whole matter into a dispute, and gaps in evidence almost always favour HMRC’s position.
Practical steps for families
Rebuild a timeline. Gather title deeds, Land Registry records, trustee minutes, bank statements and receipts. Record who paid bills, who lived in the house, and whether any rent was charged. If the property was partly held in a discretionary trust, check whether 10-year periodic charges were reported and paid — the maximum rate is 6% of trust property value above the NRB, but for most family homes within the NRB this will be nil.
| Risk | Evidence to gather | Immediate action |
|---|---|---|
| Value at key dates | Valuations, sale offers, mortgage statements | Get a retrospective valuation from a RICS surveyor |
| Beneficial clarity | Wills, trust deed, beneficiary statements, income records | Agree and document beneficial shares in writing |
| Trustee duties | Minutes, correspondence, payments made | Record trustee decisions and align actions with the trust’s purposes |
Tribunal case study: Afsha Chugtai v HMRC and gifts with reservation of benefit rules
We summarise this case because it is a clear example of how behaviour — not paperwork — determines the IHT outcome. Mohammed Chugtai set up two lifetime trust arrangements in February 2000: one over funds in an Abbey National account (later held at Santander) and one over property at Henley Road, Caversham. He was excluded as a beneficiary under both trust deeds; his children were named as beneficiaries instead. He died in February 2017.
Background facts
HMRC issued a determination in August 2022 valuing the total chargeable estate at £843,950. That included £380,000 for Henley Road and £62,239 for the Santander account. In total, £442,239 of trust property was pulled back into the estate under the GROB rules — meaning the family faced IHT at 40% on assets they believed had been given away 17 years earlier.
Tribunal focus and decision
The First-tier Tribunal found that Mohammed had kept using the Santander account for personal bills, rent receipts and property outgoings throughout the trust’s existence. Despite being formally excluded as a beneficiary, his day-to-day behaviour showed continued personal benefit. The tribunal applied the GROB rules and held the assets were not enjoyed to his exclusion in the relevant period. The appeal was dismissed.
This is a textbook illustration of why the GROB rules exist. If you give away an asset but continue to benefit from it — even informally — HMRC treats that asset as still forming part of your estate for IHT purposes, regardless of how long ago the transfer took place. Unlike the seven-year rule for PETs, there is no time limit on GROB: the question is simply whether the donor was excluded from benefit at the date of death.
Practical tests for trustees and beneficiaries
- Control: who paid bills from the trust account? If the settlor is making personal payments, that is evidence of continued benefit.
- Benefit: who lived in the trust property and who received any rental income? The settlor must be genuinely excluded.
- Evidence: bank statements, receipts and formal trustee decisions recorded in dated minutes. Without this paper trail, HMRC’s position will almost certainly prevail.
| Risk | What shows continuing benefit | How to prevent it |
|---|---|---|
| Using trust funds | Personal payments from the trust account by the settlor | Maintain completely separate personal and trust bank accounts; record every trustee payment with a formal minute |
| Occupying trust property | Settlor living in the property rent-free; household costs paid by the trust | Charge full market rent under a formal tenancy agreement; document tenancy terms and ensure rent is actually paid |
| Lack of records | No trustee minutes, receipts or formal decisions | Keep dated minutes for every trustee decision, retain valuations and file all correspondence |
Key takeaway: the trust deed alone did not stop the IHT charge. Behaviour decided the outcome. A properly structured trust — with the settlor genuinely excluded from benefit and trustees who maintain clear records — would have produced a very different result.

Tribunal case study: HMRC wins against the home-loan double-trust IHT planning scheme
The Pride decision is a clear example of what goes wrong when artificial liability mechanics try to erase a home’s value from an estate.
The planning aimed to remove property value from the estate for IHT purposes while allowing the occupant to remain living in the home rent-free. The basic idea: sell the house into an interest in possession (IIP) trust, move value into a separate discretionary trust for the children, and create a large loan note to offset the estate value at death.
What happened in Pride
- An IIP trust from 2002 gave Mrs Pride a life interest entitling her to live in the home.
- The house was sold to the trustees for £800,000; the trustees owed that amount back as a debt.
- A flat was bought for £535,000 for her use and a loan note with a long redemption schedule was issued to the children’s discretionary trust.
- On Mrs Pride’s death in October 2016, the trust property fund was worth £3,013,942 and the executors sought to deduct the loan note from the estate value to reduce the IHT bill.
The tribunal held the deduction failed. Anti-avoidance provisions prevent deducting liabilities created by the deceased (or arrangements made at their direction) where the purpose was to reduce the IHT charge. In plain terms, you cannot manufacture a debt during your lifetime that wipes out the IHT bill at death. HMRC’s position was upheld in full.
What this means now
- Many legacy home-loan and double-trust schemes set up during the early 2000s remain in place. Families relying on these arrangements should assume HMRC will challenge the deduction — and the tribunal record shows HMRC is winning these cases consistently.
- We advise taking specialist advice before any sale, appointment of capital out of the trust, or reporting event tied to a death. Unwinding a failed scheme after death is far more expensive than reviewing it proactively.
- Properly structured trust arrangements — such as a Family Home Protection Trust or a Gifted Property Trust set up for genuine, documented reasons — work within the rules rather than trying to circumvent them. That is the difference between legitimate tax-efficient planning and artificial avoidance.
Trust and probate support case studies: discretionary trusts, executors, and the IHT400
After a death, a nil rate band discretionary trust created by a will often adds complex paperwork at the worst possible time. This typically feels like an overwhelming administrative burden for the executor and the family — but getting it right is essential because errors on the IHT400 can lead to penalties, interest and prolonged HMRC enquiries.
What follows matters: decisions about inheritance tax must be made promptly. The IHT400 must normally be submitted within 12 months of death, with IHT payable within six months. Executors need to confirm which assets sit inside the personal estate and which sit within the discretionary trust arrangement. Trustees must record why they act and how they value the trust assets — and those valuations must be defensible.
Trust and probate advice after death
When James left the bulk of his estate to his wife (using the spouse exemption) and directed his nil rate band of £325,000 into a discretionary trust for wider family benefit, practical questions arose immediately. Who signs elections? Which asset values apply for the IHT400? What paperwork proves the trustees’ decisions about income and capital? Does the surviving spouse’s transferable NRB need to be claimed later — and how does that interact with the RNRB of £175,000 per person if the home is ultimately passed to direct descendants? These questions need specialist answers — not guesswork.
Help with the probate process
The IHT400 is the anchor document. Executors often start collating asset lists and filling in the form themselves, but gaps are common. Missing income streams, confused estate and trust amounts, or half-completed valuation boxes invite HMRC queries. During the probate process — which typically takes 3 to 12 months, longer where property must be sold — all sole-name assets are frozen. Bank accounts, investments and property cannot be dealt with until the Grant of Probate is issued. Getting the IHT400 right first time avoids costly delays.
Managing income and capital within the trust
Good records stop most problems before they start. Trustees of discretionary trusts should keep dated minutes of every decision, separate trust bank statements, broker valuations and letters of wishes from the settlor. These show who received income, what capital was appointed out and the reasons behind each decision. Remember that a discretionary trust is taxed at 45% on non-dividend income (with the first £1,000 at basic rate) and 39.35% on dividends — so accurate record-keeping also matters for the annual SA900 trust tax return.
| Typical issue | Evidence to gather | Immediate action |
|---|---|---|
| Confusing estate and trust amounts | Will extract, trust deed, bank statements, transfer receipts | List assets separately on the IHT400 and trustee schedules |
| Missing income sources | Rental agreements, dividend slips, pension correspondence | Match every income entry to a bank credit entry |
| No record of capital appointments | Trustee minutes, payment vouchers, beneficiary receipts | Record formal minutes for each appointment and attach receipts |
| Valuation gaps | RICS surveyor reports, broker valuations, recent comparable sale prices | Obtain retrospective valuations and note the valuation date clearly |
How we help: a specialist trust and estate adviser can work with the executor to verify figures and keep the probate timetable on track. We prepare clear audit trails so trustees and executors can demonstrate the amount, value and purpose of every movement — exactly what HMRC expects to see if they open an enquiry.
- Checklist to reduce HMRC queries: maintain separate ledgers for estate funds and discretionary trust funds.
- Keep formal minutes for every trustee decision about income or capital appointments.
- Attach valuations and receipts to the IHT400 and trustee files.
- Get specialist help early — delays compound and HMRC charges interest on late IHT payments.
Working with a specialist trust and estate adviser on these matters
A specialist acts as a steady hand when tax questions become urgent for families and their existing advisers. Trust and estate matters sit at the intersection of trust law, IHT law, income tax and capital gains tax. As Mike Pugh often says, “The law — like medicine — is broad. You wouldn’t want your GP doing surgery.” The same principle applies: generalist advice on specialist trust matters can be expensive in the long run.
Typical hand-off points
Common moments when specialist input prevents problems from escalating:
- Before submitting IHT forms or agreeing asset values with HMRC — getting these right first time saves months of correspondence.
- When a trust holds property or receives income — trustees have annual filing obligations (SA900) and potential periodic charge assessments under the relevant property regime.
- If HMRC opens an enquiry or a legacy scheme (such as a home-loan or double-trust arrangement) is causing concern — early review can identify whether to settle, disclose or defend.
| Service | What we do | Outcome |
|---|---|---|
| Initial review | Clarify the key risks and agree next steps | Clear action list and evidence needed |
| Document check | Assess trust deeds, valuations, minutes and accounts | Detailed notes trustees can rely on |
| Legacy scheme review | Examine older planning arrangements in light of current tribunal decisions | Practical corrective plan or confirmation the arrangement remains sound |

Conclusion
Every example in this article shows one simple truth: behaviour matters as much as paperwork — and often more.
The same practical risks repeat across every case we see. Continued benefit by the settlor, blurred ownership, poor record-keeping and assumptions that “the trust deed will sort it out” increase IHT exposure and invite HMRC challenge. The Chugtai case shows what happens when a settlor keeps using trust funds. The Pride case shows what happens when artificial debt structures try to defeat IHT. Both ended with the family paying the full tax bill.
Get the value right, separate assets clearly, and record trustee decisions that show the declared purposes of the trust were followed in practice — not just on paper.
Remember, trusts are not set-and-forget arrangements. Over time, a trust holding property can slip from its stated aim if day-to-day actions change who really benefits. A discretionary trust can last up to 125 years under English law — but it needs active, documented administration throughout its life.
If a similar property arrangement, legacy scheme or trust still allows the settlor (or someone who should be excluded) to use funds or occupy property, review it before the next reporting date or life event. For practical steps on how trusts can be used for tax-efficient planning within the rules, see how trust funds can help with inheritance tax planning.
With timely evidence, clear records and specialist advice, most families can resolve uncertainty, protect their inheritance and reduce stress. Plan, don’t panic.
