Why the inheritance tax seven-year rule may not be the full story…

The inheritance tax seven-year rule is often summarised as: “Give an asset away, survive seven years and no inheritance tax is due.” Although that may be correct for a straightforward outright gift, the inheritance tax position can be more complicated where the donor has also made a chargeable lifetime transfer into a trust. An earlier trust gift may affect the tax on a later potentially exempt transfer, meaning executors may need to review gifts made almost 14 years before death.

Key points

• a PET is exempt if the donor survives seven years
• if a PET fails, CLTs made in the preceding seven years may reduce the nil-rate band available against it
• this can require a review of transfers made up to 14 years before death
• taper relief reduces the tax payable, not the value of the gift.

What is the inheritance tax seven-year rule?

Most outright gifts from one individual to another are potentially exempt transfers (PETs). If the donor survives for seven years after making the gift, the PET becomes exempt for inheritance tax purposes, provided the donor has not continued to benefit from the gifted asset under the gift-with-reservation rules. If the donor dies within seven years, the PET becomes chargeable and may use some or all of the available nil-rate band.

What is a chargeable lifetime transfer?

A transfer into a discretionary trust is usually a chargeable lifetime transfer (CLT). A CLT is immediately chargeable and is cumulated with chargeable transfers made in the preceding seven years when determining whether the nil-rate band has been exceeded. Even if no lifetime tax is due, it may reduce the nil-rate band available against a later failed PET.

How does the inheritance tax 14-year rule work?

There is no separate statutory inheritance tax “14-year rule”. The expression describes the extended review period that may apply when a donor dies within seven years of making a PET and had made one or more CLTs during the seven years before that PET.

First, identify PETs made within seven years of death. For each failed PET, review CLTs made in the seven years before that gift. If the failed PET was made almost seven years before death, the review can extend to almost 14 years before death.

Inheritance tax 14-year rule example: how an earlier trust gift affects a failed PET

STEP 1: Review gifts made within seven years of death

David made a £400,000 PET on 15 June 2020 and died on 30 June 2025. As he died within seven years of the gift, the PET fails and becomes chargeable.

STEP 2: Review CLTs made in the seven years before the PET

The £325,000 CLT made on 1 June 2014 falls within the seven years before the PET made on 15 June 2020. It used the full nil-rate band of £325,000:

STEP 3: Calculate the tax on the failed PET

STEP 4: Deduct taper relief

Death occurred five years and 15 days after the PET, placing the gift within the five-to-six-year taper band. Therefore, 40% of the full tax remains payable: £160,000 × 40% = £64,000.

The 2014 CLT is not charged again or added to David’s death estate. It is relevant only because it used the nil-rate band available against the failed PET.

This simplified example assumes no exemptions, reliefs or other relevant transfers, a £325,000 nil-rate band, and that no transferable nil-rate band is available.

How does taper relief work?

Taper relief reduces the inheritance tax payable on a failed gift, not the value of the gift. It applies only where death occurs more than three years after the gift and tax is payable on that gift.

Why historic trust transfers matter

An old discretionary trust transfer may still reduce the nil-rate band available against a later failed PET. Executors should not assume that a transfer is irrelevant merely because it occurred more than seven years before death.

Who pays inheritance tax on a failed PET?

The recipient is generally primarily liable for inheritance tax on a failed PET. A will, estate arrangement or private agreement may determine who ultimately bears the cost between the parties, but does not alter the statutory liability. The personal representatives may also become liable if the tax remains unpaid after the statutory period.

What records should executors check?

• outright gifts made within seven years before death, including the date, recipient, value and purpose of each gift
• CLTs made in the seven years before each failed PET, even where the CLT itself was made more than seven years before death
• the date, recipient, value and valuation basis of each transfer
• any exemptions or reliefs claimed, together with the records supporting each claim
• any lifetime inheritance tax paid, including the payment date and supporting calculation.

Conclusion

The inheritance tax seven-year rule is only a starting point. Where a PET fails, earlier CLTs may reduce the nil-rate band available against it, requiring executors to review transfers made almost 14 years before death. Because the order and timing of gifts can materially affect the calculation, executors and families dealing with a potentially taxable estate should seek professional advice before finalising the inheritance tax position.
