Family Loan Strategy: Lending to Children Without Triggering IHT

A loan to a child is not a gift. That single distinction is the foundation of one of the most practical and underused strategies in UK estate planning. Where a gift to a child reduces the parent's estate immediately, and starts the seven-year clock for IHT purposes, a genuine loan does not. The money remains a debt owed back to the parent, and the outstanding balance forms part of their estate as an asset. No IHT is triggered on the lending. No potentially exempt transfer is created.


The utility of this approach comes not from a clever mechanism but from a straightforward feature of how IHT works: debts owed to the estate by third parties, including family members, are assets of the lender's estate. They are included in the IHT calculation on death at their outstanding value. The estate still holds the asset; it has simply changed form from cash to a loan receivable.


Where the strategy becomes interesting, and where most articles fail to explain the detail, is in what can be done with the loan subsequently to achieve a genuine estate reduction without the limitations of the gift route.


Why Families Use Loans Rather Than Gifts

The most common motivation is straightforward: the parent wants to help a child buy a property, fund a business, or manage a financial pressure, but does not want to make an irrevocable gift and is not confident they will not need the capital themselves in future. A loan preserves flexibility in a way that a gift does not.

Beyond flexibility, there are several specific tax situations where a loan is preferable to a gift from the outset.


Where the parent's estate is already above the nil-rate band and RNRB thresholds, gifts are potentially exempt transfers that reduce the estate for IHT only if the parent survives seven years. A loan reduces nothing immediately but opens up options: forgiveness of the loan debt, partial write-off over several years, or a planned reduction that can be timed and structured more deliberately than a single gift made in one transaction.


There is no inheritance tax to pay on gifts between spouses or civil partners. You can also give away gifts worth up to £3,000 in total each tax year, carry forward one year of unused allowance, give wedding gifts up to £5,000 to a child, and make gifts from surplus income. Beyond these exemptions, any other gifts are potentially exempt transfers and fall outside the estate only if the donor survives seven years.


For a parent wanting to transfer meaningful sums, £50,000, £100,000, or more, to a child, the gift route carries IHT risk if death occurs early. The loan route carries no immediate IHT consequence, and the planned forgiveness can be structured over time.


What Makes a Loan Genuine: The Requirements

This is where many family arrangements fail HMRC scrutiny. An informal transfer of money described as a loan, but with no repayment terms, no interest, no documentation, and no expectation of repayment, is likely to be treated by HMRC as a gift. The substance of the arrangement governs, not the label applied to it.


For a family loan to be treated as a genuine debt:


  • Documentation is essential. A written loan agreement, signed by both parties, should record the amount lent, the date, the repayment terms, and the interest rate (if any). The agreement does not need to be a formal legal document, but it should be sufficiently clear that an objective third party, including HMRC reviewing the estate after the lender's death, could identify it as a genuine debt.

  • Repayment terms must be realistic. A loan stated to be repayable "on demand" or in full at a specific future date is more credible than one with no repayment mechanism at all. Where the borrower genuinely cannot repay for a defined period, for example, because the funds are tied up in a property purchase, a realistic repayment schedule should reflect that.

  • Interest is not essential for genuineness, but it matters. A loan at zero interest does not disqualify the arrangement as a genuine debt, but the absence of interest is one of the factors HMRC may weigh when assessing whether the arrangement was truly commercial or merely a gift in loan clothing. More significantly, a loan at zero interest may create an income tax issue for the lender if the loan exceeds £5,000 and falls within the beneficial loan provisions, though these typically apply to employer-employee relationships rather than family loans.

  • The loan must appear on the estate's IHT400. When the lender dies, the executor must disclose the outstanding loan as an estate asset. The IHT400 return asks specifically for debts owed to the deceased. Failing to declare a family loan is a compliance failure, and HMRC has increasingly focused on undisclosed family financial arrangements in IHT enquiries.


The Estate Reduction Mechanism: Writing Off the Loan

Here is the core planning structure. Once the loan is established and documented, the lender can choose to forgive part or all of it , gradually or at once. Each forgiveness of a loan balance is a gift at that point in time. The forgiven amount is a potentially exempt transfer, and the seven-year clock starts running from the date of forgiveness.


This allows the parent to:

●      Lend a substantial sum to the child, maintaining access to the capital as a receivable debt

●      Test over time whether the capital is genuinely not needed for their own living costs

●      Forgive a portion each year, for example, £3,000 per annum using the annual gift exemption, or larger amounts as deliberate PETs timed to coincide with periods of good health

●      Use the normal expenditure out of income exemption to forgive interest-equivalent amounts annually without starting any seven-year clock

●      Leave any outstanding balance in the estate at death, as a deductible liability against the estate if the loan was to the lender (not owed by the lender to the estate)


The last point requires clarification. An outstanding loan owed to the deceased is an estate asset, included in the estate value for IHT. But an outstanding loan owed by the deceased to another party is a liability, deductible from the estate. The family loan strategy works by the parent being the lender, the creditor, and the estate holding the debt as an asset. This is the reverse of an arrangement where the child lends to the parent, which would reduce the parent's estate through a deductible liability.





The Written-Off Loan vs the Gift: Why the Distinction Matters

A gift of £50,000 made today is a PET that falls outside the estate in seven years. For a parent aged 75 in moderate health, survival for seven years from today is uncertain.

A loan of £50,000 made today, followed by annual forgiveness of £10,000 per year starting next year, produces five separate PETs each of £10,000. The first of those PETs falls outside the estate in seven years from the first forgiveness date. Even if the parent dies before the full loan is forgiven, only the forgiveness tranches within seven years of death are brought back as failed PETs; the outstanding loan balance remains in the estate as an asset at its outstanding value, but the forgiven tranches that survived seven years are entirely outside the estate.


Compare this to the single gift: if the parent makes a single gift of £50,000 and dies four years later, the full £50,000 is a failed PET subject to taper relief. Under the loan-and-forgiveness structure, only the tranches forgiven within seven years of death are brought back; the tranches forgiven more than seven years before death are entirely exempt.


The IHT Deduction for Debts: What HMRC Requires

When the borrower's estate owes a debt to a third party at death, that debt is a liability deductible from the estate for IHT. The reverse position, a loan owed to the deceased, is an asset included in the estate.


For family loans, HMRC has specific anti-avoidance rules that prevent the simple creation of debts between connected parties from being used to artificially reduce an estate.


A debt is only deductible from an estate for IHT purposes where the debt was incurred for consideration in money or money's worth, and the consideration has been applied for the benefit of the deceased or for the benefit of a third party in fulfilment of the deceased's legal obligation. A debt created artificially to reduce the estate, without genuine consideration, is not deductible.


This rule matters particularly in the reverse scenario: where a parent owes money to a child, perhaps for care services provided, or as a repayment of a loan the child made to fund the parent's care. HMRC will scrutinise whether such debts reflect genuine commercial transactions or were manufactured to create a deductible liability.


The family loan strategy works because the parent is the lender, not the borrower. The loan receivable is an estate asset, not a deductible liability. The IHT anti-avoidance rules on deductible debts are therefore not directly in play; the concern for the planning strategy lies elsewhere.



Income Tax on Interest: The Overlooked Dimension

A family loan at zero interest is entirely valid for IHT planning purposes, but the income tax position deserves attention, particularly where the lender is a higher-rate taxpayer with rental income, pension income, or investment returns.


If the parent charges interest on the loan to the child, that interest is income of the parent, taxable at their marginal rate. For a higher-rate taxpayer, this represents a 40% or 45% drain on income that might otherwise compound tax-free or be deferred. Where the planning purpose is estate reduction, charging interest increases income, which may increase income tax, without reducing the estate. The outstanding loan balance plus accumulated interest is still in the estate.


For this reason, most family loan strategies use zero interest or a nominal rate. The absence of interest does not invalidate the loan for IHT purposes, and it avoids creating taxable income for the lender.


Where the loan is used by the child to purchase a residential property to let, a different consideration arises. The child, as borrower, cannot typically deduct family loan interest against rental income unless the loan is on commercial terms and the interest is genuinely paid. If the child pays interest to the parent, the parent declares it as income and the child deducts it against rental profits, a broadly neutral result. If no interest is charged, neither income nor deduction arises for either party.


Loans Secured Against Property

Family loans to fund property purchases are sometimes secured against the property, giving the parent a legal charge over the child's home. This provides a degree of security for the lender and may make the arrangement more credible as a genuine commercial debt.


From an IHT perspective, a secured loan is treated the same as an unsecured one: the outstanding balance is an estate asset of the lender. The security does not affect the IHT treatment of the loan receivable.


What the security does affect is the position on the child's eventual property sale. If the parent holds a legal charge over the property, that charge must be discharged before the property can be sold with clean title. This requires the outstanding loan to be repaid or forgiven at that point, which may accelerate the gifting timetable in a way the parent did not anticipate. Families who use secured loans should ensure the loan agreement clearly addresses what happens to the security if the property is sold before the loan is repaid.


There is also a Land Registry registration requirement: a legal charge over residential property must be registered to be enforceable against third parties. An unregistered charge provides limited protection if the property is sold or if the child becomes insolvent.


Director Parents and Self-Employed Borrowers

For a parent who is a company director and wants to lend to an adult child who is also a director of the same company, the transaction requires care. A loan from the parent personally to the child personally is a private financial arrangement. A loan from the parent's company to the child, or from the parent to the child who then uses the funds to benefit the company, raises associated company loan and close company rules that must be separately reviewed.


The clean version of this arrangement is a direct personal loan from parent to child, documented as a private transaction, with the child free to use the funds as they choose. Involving company structures adds complexity without necessarily improving the IHT outcome.


For self-employed parents with variable income, the loan strategy also interacts with the normal expenditure out of income exemption. Where the parent has genuine surplus trading income each year, they can forgive a portion of the loan annually as normal expenditure out of income, entirely free of IHT, with no seven-year clock. This route requires documentation of the income, expenditure, and the pattern of forgiveness, but it can enable relatively large annual write-offs without PET exposure.


What Happens to the Outstanding Loan at Death

When the lender parent dies with an outstanding family loan on their books, the executor must include the loan balance as an estate asset in the IHT400. The outstanding amount is valued at the amount legally owed, including any unpaid interest if interest was contractually due.


HMRC may challenge the value of the loan where repayment is uncertain. A loan owed by an insolvent child, or one where there is no realistic prospect of recovery, may be valued at less than face value, or even at nil, for IHT purposes if it can be demonstrated that the debt is unrecoverable. However, this discounting works against the estate planning purpose: a loan treated as worthless by HMRC for IHT (because it is irrecoverable) may simultaneously expose the lender's estate to an argument that the loan was effectively a gift from the outset.


This creates a practical tension. A family loan must be documented as a genuine debt to avoid being treated as a gift when made. If it becomes uncollectable over time, the valuation question arises on death. The best protection is for the loan to be genuine in its terms and realistic in its repayment expectations throughout the arrangement, not merely genuine when created and then allowed to drift into being worthless.





The Deduction Position for the Child

Once the parent dies, the outstanding loan, if not forgiven before death, is an estate asset. The child, as borrower, owes the outstanding amount to the estate. On finalisation of the estate, the executor will either collect the debt from the child (generating cash for distribution to beneficiaries) or forgive it as part of the estate distribution.


Where the child is also a beneficiary of the estate, the practical outcome is often that the loan is set off against the child's inheritance. This is an entirely legitimate mechanism, and many family loan arrangements are structured from the outset with the expectation that the loan will be partially or fully settled against the estate on the parent's death. The result is that the child receives a reduced share of the estate, but has had the use of the capital throughout the loan period.

Practical Steps for Establishing a Family Loan

Draft a loan agreement. It does not need to be elaborate, but it must record the amount, date, borrower, lender, repayment terms, and interest rate (or confirmation that no interest is charged). Both parties should sign it.

Ensure the transfer is traceable. Bank transfers with a clear reference, "loan per agreement dated [date]" , create an audit trail. Cash payments are harder to evidence and create ambiguity about whether a loan or gift occurred.

Keep repayment activity consistent with the agreement. If the agreement says the loan is repayable on demand, and several years pass with no demand or repayment, HMRC may view the arrangement as substance-free.

Document forgiveness separately. Each time a portion of the loan is forgiven, whether using the annual exemption, as part of a deliberate PET, or under the normal expenditure out of income route, that forgiveness should be documented in writing to the borrower, noting the date, amount, and exemption or treatment applied.

Declare the loan in the IHT400. The executor must include the outstanding balance in the estate. Failure to disclose is a compliance failure that could lead to penalties and interest.


Key Takeaways

●      A genuine family loan does not reduce the lender's estate; the outstanding balance is an estate asset. No PET is created at the point of lending. The planning benefit comes from the flexibility to forgive the debt strategically over time.

●      For the loan to be treated as genuine, it must be documented, have realistic repayment terms, and not be so obviously non-commercial that HMRC treats it as a gift from the outset. Substance matters more than the label.

●      Forgiveness of the loan debt is a gift at the point of forgiveness. The annual exemption (£3,000), the normal expenditure out of income exemption, and deliberate PETs can all be used to systematically reduce the outstanding loan in a tax-efficient way.

●      Gifts from surplus income that are habitual, made out of income rather than capital, and do not reduce the donor's standard of living are entirely exempt from IHT with no seven-year clock. This exemption can be applied to interest-equivalent loan forgiveness annually, enabling meaningful estate reduction without PET exposure. TaxYZ

●      A loan at zero interest is valid for IHT purposes and avoids creating taxable income for the lender. The absence of interest is not, on its own, evidence that the arrangement is not a genuine debt.

●      Outstanding family loans at death must be disclosed in the IHT400. HMRC's scrutiny of undisclosed family financial arrangements has increased, and transparency in the estate return is essential.



FAQs

Q1: If a parent lends money to a child and later the child cannot afford to repay it, does HMRC automatically treat the original loan as a gift?

A1: Well, it is worth noting that HMRC does not automatically reclassify a loan as a gift simply because repayment becomes difficult or does not occur as scheduled. The question HMRC asks is whether the arrangement was genuinely a loan when it was made, not whether it was ultimately repaid in full and on time. A loan that was properly documented, made on realistic terms, and treated by both parties as a genuine debt remains a loan for IHT purposes even if the borrower later faces financial difficulties and repayment is extended, restructured, or partially forgiven.


What HMRC scrutinises is the substance of the arrangement from the outset. If there was a written agreement, if repayments occurred initially even if they later stopped, and if there was a genuine expectation of repayment when the loan was made, those factors support the loan characterisation. Where the estate faces a difficult position at the lender's death is the valuation question, an uncollectable loan may be valued below its face value, as discussed in the article. But that valuation issue is separate from the question of whether the original transfer was a loan or a gift. The documentation made at the time of the loan is therefore not merely administrative tidiness; it is the evidence that determines the IHT outcome years later.


Q2: Is there a maximum amount a parent can lend to a child under a family loan arrangement without attracting HMRC attention?

A2: In my experience, there is no statutory threshold above or below which family loans automatically attract or avoid HMRC scrutiny. HMRC can enquire into any estate regardless of the loan amount, and the principles that determine whether a loan is genuine, documentation, realistic terms, genuine expectation of repayment, apply equally to a £10,000 loan and a £500,000 loan. That said, the practical reality is that larger loans face greater scrutiny on death, because the stakes for HMRC are higher and the IHT difference between treating the amount as a loan receivable (included in the estate) versus a gift made several years ago (potentially outside the estate) is more material.


A loan of £500,000 made five years before death, if treated as a gift rather than a loan, could reduce the estate by £500,000, potentially saving £200,000 in IHT, which is precisely the scenario HMRC focuses on when reviewing IHT400 returns. For larger loans, the documentation should be correspondingly more robust: a formal loan agreement, evidence of bank transfer rather than cash, records of any repayments or forgiveness, and clear evidence that the lender retained a realistic expectation of repayment throughout. The loan should appear on any statement of the lender's assets at any point, for instance, if they complete a means-tested benefits application or arrange care funding, to demonstrate consistency in how the arrangement was presented.


Q3: If a parent lends money to a child who uses it to buy a house, and the house increases in value, does any of that growth belong to the parent for IHT purposes?

A3: Well, this is one of the more satisfying aspects of the family loan strategy from a planning perspective. The short answer is no, the capital growth on the property belongs entirely to the child, not to the parent. The parent's estate holds a loan receivable equal to the outstanding loan balance. The value of that receivable does not increase with the property value. If the parent lent £100,000 and the child's house increases in value by £80,000, the parent's estate still holds a loan receivable worth £100,000 (assuming no forgiveness or repayment has occurred). The £80,000 growth belongs to the child.


This is one of the structural benefits of the loan approach compared to an equity stake. Had the parent taken a share of the property rather than making a loan, for example, contributing to the purchase in exchange for a percentage of the title, that share would form part of the parent's estate at its current market value, growing alongside the property. A loan at a fixed face value does not compound in the same way. The child, as property owner, benefits from the full appreciation. The parent retains a fixed-value asset in their estate. Over time, if the loan is systematically forgiven while the property grows, the estate planning efficiency increases, the parent is reducing a fixed-value liability rather than a growing equity interest.


Q4: Can a parent lend money to a child who is going through a divorce, and if so, what happens to the loan during the divorce proceedings?

A4: Well, this is a scenario that involves two different legal regimes operating simultaneously, and the intersection can be complicated. From a pure IHT perspective, the loan remains an asset of the parent's estate regardless of the borrower's personal circumstances, divorce does not extinguish the debt or convert it into a gift. However, in divorce proceedings, the courts assess the financial resources of each spouse, and a family loan owed to a parent is a liability of the borrowing spouse. This liability reduces the borrowing spouse's net worth for the purposes of the financial settlement. This can be both an advantage, genuinely reducing the pot available for division, and a source of dispute, particularly if the other spouse argues the loan was actually a gift from the parent designed to reduce the apparent marital assets.


Family courts are alert to this and will scrutinise the terms of any family loans made around the time of relationship breakdown. Where a loan was established well before marital difficulties arose and has been consistently documented and treated as a genuine debt, it is more likely to be accepted as a genuine liability in the financial settlement. A loan manufactured close to the separation date, with little documentation, faces much higher risk of being treated as a resource available to the family. Parents considering lending to a child who is experiencing marital difficulties should take both IHT advice and family law advice before proceeding.


Q5: What is the income tax treatment for the parent if they charge a commercial rate of interest on a family loan, and does the child get any tax relief?

A5: Well, charging commercial interest on a family loan creates a straightforward but often overlooked income tax picture for both parties. For the parent, interest received on a loan, even a family loan, is savings income, taxable at the savings income rates. For 2026/27, the personal savings allowance is £1,000 for basic-rate taxpayers and £500 for higher-rate taxpayers, with no allowance for additional-rate taxpayers. Interest above those thresholds is taxable at 20%, 40%, or 45% depending on the parent's total income position. So a parent charging 3% interest on a £200,000 loan generates £6,000 of annual interest income.


If they are a higher-rate taxpayer, £5,500 of that is taxable at 40%, a tax cost of £2,200 per year simply for charging a commercially reasonable rate. For the child, the interest paid on a family loan is deductible against rental income if the loan was specifically used to purchase a buy-to-let property and the interest is genuinely paid. This matching, parent paying income tax on interest received, child deducting it against rental income, can produce a neutral or even mildly tax-efficient outcome if the child's marginal tax rate is higher than the parent's. For loans used for personal purposes, a primary residence, living costs, or a business, the child gets no income tax deduction on interest paid to a family member. In most family loan arrangements, charging zero interest is simpler, avoids creating taxable income for the parent, and does not affect the loan's validity for IHT purposes.


Q6: If a parent in Scotland lends money to a child, are there any differences in how the loan or its forgiveness is treated compared to England?

A6: Well, IHT is reserved Westminster legislation and applies identically across the UK regardless of where the lender or borrower lives. The principles governing family loans, the treatment of forgiveness as a potentially exempt transfer, the seven-year clock, and the estate inclusion of the outstanding loan balance are all the same for a Scottish parent as for one in Yorkshire or Kent. Where Scottish law does differ is in the private law aspects of the loan, the law governing the loan agreement itself and the rights of the parties. Scottish contract law has some differences from English law, particularly around how contracts are formed and enforced.


A solicitor preparing a loan agreement for a Scottish family arrangement should use a Scottish law framework, but the IHT consequences that flow from the arrangement are unaffected by which legal system governs the contract. The income tax on any interest charged also applies at the same rates, though Scottish income tax rates apply to the parent's employment and other non-savings income, the interest from the family loan is savings income taxed at UK-wide savings rates regardless of Scottish residence. This means a Scottish parent charging interest on a family loan faces the same savings income tax treatment as an English parent. The planning considerations and documentation requirements are therefore identical north and south of the border.



Q7: Can a parent use a family loan to fund their child's business, and does the loan become a deductible business expense for the child?

A7: In my experience, lending to a child's business rather than to the child personally is one of the most practically useful applications of the family loan strategy, and it has an additional income tax benefit that direct personal loans do not. When a loan is made to a child for use in their trading business, the interest paid on that loan may be deductible against the business's trading profits, provided the loan is genuinely used for business purposes and the interest is genuinely charged and paid. This is a legitimate business expense deduction under the normal rules for interest on borrowings used for trade.


The parent declares the interest as savings income; the child's business deducts it as a trading expense. If the child's business is profitable and the marginal tax rate on business profits is 40% or 45%, while the parent's savings income rate is 20%, the interest charge can produce a net tax saving across the family unit. Beyond the income tax angle, the IHT position is the same: the loan is an estate asset of the parent, and forgiveness is a gift at the time it occurs. Where the business grows substantially in value, the child's increased business wealth reflects the benefit of having access to the loan capital, but that growth belongs to the child, not to the parent's estate. A parent who lends to a child's business and forgives the loan gradually is transferring value at a fixed nominal amount while the business asset grows in the child's hands.
