IHT and Family Loans UK: Lending Money to Family, Loan Write-Offs on Death, and Whether Loans Reduce Your Estate
A loan to a child stays in your estate as a debt owed to you — it is not a gift. To turn a family loan into an IHT-saving gift, write it off during your lifetime (starting the 7-year clock). A will clause forgiving a loan does not reduce the IHT charge on the estate.
IHT Treatment of Family Loans
A loan to a family member is not a gift for IHT
When a parent lends money to a child, they create a legal debt: the child owes the money back. The parent has not made a gift — they have exchanged cash for a legal right to repayment. For IHT: the outstanding loan balance at the date of the parent's death is an asset of the parent's estate, included at its face value (or realisable value if lower). Lending money to a child does not reduce the parent's estate for IHT — the estate simply holds a loan receivable rather than cash. Any interest received on the loan is income of the lender, taxable in the usual way. The loan reduces the child's net assets (they owe a debt) but for the lender's estate, the loan is an asset, not a deduction.
Interest-free loans: HMRC's 'associated operations' risk
An interest-free loan to a family member is economically valuable to the borrower. HMRC has considered whether an interest-free loan, combined with other transactions, could constitute an 'associated operation' under section 268 IHTA 1984 — a series of linked transactions treated as a single composite transfer of value. In practice, HMRC is more likely to challenge interest-free loans where: (1) the loan is connected to another transaction (e.g. the borrower uses the loan to fund a purchase where the lender retains a benefit); or (2) the loan is part of a structured tax avoidance arrangement. A straightforward, documented, genuinely repayable interest-free family loan is unlikely to be challenged as an associated operation in isolation. However, the lender's estate still includes the outstanding principal at death.
Writing off a loan during the lender's lifetime
A lender can forgive a loan during their lifetime — releasing the borrower from the obligation to repay. The moment the loan is written off, the lender has made a gift of the outstanding balance. This is a potentially exempt transfer (PET): it starts the 7-year clock at the date of write-off. If the lender survives 7 years from the write-off, the amount is outside the estate. If the lender dies within 7 years, the written-off amount is a failed PET with taper relief for deaths 3–7 years after the write-off. A loan write-off is therefore a valid IHT planning step — converting a non-IHT-saving loan into a gift with a running 7-year clock. The write-off must be documented in writing: a deed of release or signed letter confirming the debt is permanently forgiven.
Writing off a loan in a will
A common will provision forgives outstanding loans to children: 'I release my children from any outstanding loans at the date of my death.' When this takes effect on death, the loan is an asset of the estate at death — included in the estate for IHT calculation. The will then releases the debt as a legacy. The loan is taxed as part of the estate first; the forgiveness is then treated as a legacy (reducing the residue available to other beneficiaries). This differs from a lifetime write-off (PET). A will clause does not reduce the IHT charge on the estate. For IHT saving, lifetime write-offs are more effective than will provisions.
Deathbed loans: blocked by section 103 Finance Act 1986
A deathbed loan is where a terminally ill person borrows money shortly before death and gifts the borrowed funds to family, hoping to reduce the estate. Under section 103 FA 1986, where a liability (the loan) is connected to the acquisition of property that is excluded from the estate or was incurred as part of an arrangement to reduce IHT, the liability is not deductible from the estate. HMRC's approach: if a person borrows £500,000 and immediately gifts it to their children, the loan is not deductible — HMRC includes the gift (if within 7 years) as a failed PET and does not allow the borrowing to reduce the estate. The result is double-counting. Deathbed loan arrangements do not save IHT and may trigger GAAR (General Anti-Abuse Rule) scrutiny.
Practical planning: using family loans correctly
Used correctly, family loans can support IHT planning. Key points: (1) Document every loan — a signed loan agreement with clear repayment terms; for interest-free loans, state explicitly that no interest is charged. (2) Convert a loan to a gift over time: write off the loan in tranches using the £3,000 annual exemption or as a series of PETs with running 7-year clocks. (3) Where a loan is secured on the child's property (a legal charge), it is clearly a loan receivable in the estate — but the child's property is reduced by the debt owed back. (4) Distinguish family loans from loan trust arrangements: a loan trust is a specific IHT product where a settlor lends funds to a trustee (who invests in a life policy bond) — growth accrues outside the estate while the original loan remains in the estate. These are structured products, not the same as a straightforward family loan.
Frequently Asked Questions
Does lending money to my child reduce my estate for IHT?
No. When you lend money to your child, the loan is an asset of your estate — you have exchanged cash for a right to repayment. The outstanding loan balance at your death is included in your estate for IHT at its face value. Lending does not reduce your estate. To reduce your estate, you would need to gift the money (a PET, 7-year clock starts) or write off the loan during your lifetime (treated as a gift at the point of write-off).
Can I write off a loan to my child in my will to save IHT?
Not directly. A loan forgiven in your will does not reduce the estate for IHT — the loan is valued in the estate first, and the forgiveness is treated as a legacy after IHT is calculated. For IHT saving, a lifetime write-off is more effective: the moment you release the debt during your lifetime, it becomes a PET that starts the 7-year clock.
Is an interest-free loan to a family member a gift for IHT?
No — an interest-free loan is not a gift for IHT purposes. The lender retains the right to repayment of the principal. The economic benefit of interest-free borrowing is not itself a gift. HMRC may challenge arrangements where an interest-free loan is linked to other transactions as associated operations under s268 IHTA 1984, but a standalone documented family loan is unlikely to be challenged.
What happens to an outstanding loan to my child when I die?
The outstanding loan balance is an asset of your estate at death, included for IHT at its face value. Whether it is then repaid by your child to the estate (increasing the residue for distribution) or forgiven under your will (treated as a legacy) depends on what your will provides. If the will is silent, the debt is owed to the estate and must be repaid.
Can I borrow money and give it away to reduce my estate?
No. This deathbed loan arrangement is blocked by s103 FA 1986. The loan (borrowing) is not deductible from the estate where it was incurred to make a gift. HMRC includes the gift as a failed PET and ignores the borrowing — resulting in double IHT exposure. The GAAR may also apply. Deathbed loan arrangements do not work as IHT planning.
Make Sure Your Will Handles Outstanding Loans Correctly
If you have outstanding loans to family members, your will should address them clearly — whether they are to be repaid to the estate or forgiven as a legacy. WillSafe will kits include provisions for specific legacies and residue direction.
