Gifts With Reservation of Benefit — The IHT Trap Most Families Miss

Giving assets away during your lifetime is one of the most widely used inheritance tax planning strategies in England and Wales. The idea is simple: hand the asset over, survive seven years, and it falls out of your estate for IHT. But if you give something away while continuing to benefit from it, HMRC treats the gift as if it never happened.

This is the gifts with reservation of benefit rule, or GROB. It was introduced by section 102 of the Finance Act 1986 to shut down a common planning technique — parents gifting the family home to their children while continuing to live in it rent-free. We see clients every month who have done exactly this on well-meaning advice and are horrified to find the gift has achieved nothing for IHT purposes.

This guide explains what a GROB is, why the seven-year rule does not save it, how the pre-owned assets tax charge catches taxpayers who try to sidestep it, and the planning techniques that genuinely work in 2026.

What is a gift with reservation of benefit?

A gift with reservation of benefit arises when someone gives an asset away but either does not fully part with possession and enjoyment of it, or continues to benefit from it. The rule sits in section 102 of the Finance Act 1986 and catches any gift made on or after 18 March 1986.

The consequence is stark. For IHT, the asset is treated as remaining part of the donor’s estate for as long as the reservation continues. If it is still in place at the date of death, the full open-market value at that date is added back into the estate and taxed at 40% above the available nil-rate bands. The nil-rate band remains £325,000 and the residence nil-rate band £175,000 in 2026, with the £2 million taper threshold unchanged.

The rule bites regardless of intention. Whether the donor deliberately structured the arrangement to dodge IHT or simply carried on using the asset out of habit, HMRC applies the same treatment.

The classic trap — gifting the family home

The most common GROB scenario involves the family home. A widowed parent, worried about care fees or IHT, transfers the deeds of their house into the names of their adult children. The parent continues to live there rent-free, sometimes for many years. When the parent dies, the family assumes the property is safely out of the estate because the seven-year clock has long since expired.

It is not. The parent has given away legal ownership but has reserved the benefit of continuing occupation. The house comes back into the estate at its date-of-death value. If it is worth £600,000 and the estate has used its nil-rate band, that mistake can cost £240,000 in IHT the family did not expect and often cannot easily fund.

Why the seven-year rule does not save it

Most people know that gifts become fully exempt from IHT if the donor survives seven years. That is the potentially exempt transfer regime, which applies to outright gifts to individuals. A GROB is different. The seven-year clock does not start until the reservation ends — until the donor stops benefiting from the asset.

So if a parent gives the house to the children in 2005 but continues to live there until death in 2026, the seven years have not run at all for GROB purposes. If the parent moves out in 2020 and dies in 2026, the reservation ended in 2020 and the seven-year clock started then, but the gift is treated as being made in 2020 at the 2020 value, not the 2005 value.

HMRC’s overview of the gift rules is at gov.uk/inheritance-tax/gifts, and the underlying legislation at legislation.gov.uk.

Pre-owned assets tax — the income tax backstop

Some taxpayers tried to design their way around GROB using elaborate structures such as complex trust arrangements or reversionary leases. In response, the Finance Act 2004 introduced the pre-owned assets tax charge, or POAT. Where a taxpayer has given away an asset but continues to enjoy it, and the arrangement escapes GROB on a technicality, POAT imposes an annual income tax charge on the deemed benefit of continuing use.

For land and buildings the charge is based on market rent. For chattels such as paintings or antiques it uses an official rate applied to the asset’s value. POAT does not remove the asset from the estate, but it means clever workarounds carry a live annual cost. HMRC’s guidance is at gov.uk. Taxpayers can elect out of POAT and back into GROB treatment, but this is rarely attractive because it defeats the point of the original planning.

Ways to make gifts of the family home effective

There are legitimate ways to gift a property and genuinely remove it from your estate. Each has conditions and pitfalls, and we always recommend advice from a solicitor before proceeding.

The first is shared occupation. HMRC accepts that a gift of an undivided share is not a reservation of benefit if the donee also occupies the property and both parties share the outgoings on an equitable basis — typically a parent gifting a half share to a child who then moves in, with both contributing to bills. The occupation must be genuine and continuous, not token.

The second is market rent. A parent can gift the property outright and then pay a full market rent to the new owners. The rent must be genuinely paid, at market rates, and reviewed periodically. The children pay income tax on the rent, but the property is outside the estate provided the parent survives seven years.

The third is proportionate retention. Instead of gifting the whole property, the donor keeps a proportionate share reflecting their continuing use and gifts only the balance. Because they benefit only from the share they still own, there is no reservation.

Cash gifts used to buy property — a safer route

Gifting cash is treated very differently from gifting a specific asset. If a parent gives an adult child a lump sum, and the child then uses it to buy a property, the parent has made a straightforward potentially exempt transfer. Provided the parent survives seven years, the money falls out of the estate.

Crucially, the parent can then live in that property with the child’s permission without triggering GROB. HMRC treats the gift as being of the cash, which has already been spent, not of the property. This is a well-established route, but the child must genuinely own and control the property — sham arrangements are always vulnerable to challenge.

Life interest trusts, holiday homes and chattels

What about the holiday cottage the family occasionally uses, or the painting on the wall gifted years ago? The GROB rules apply to any benefit reserved, but HMRC accepts that occasional, incidental use does not amount to a reservation. A parent who gifts a holiday home and stays there once or twice a year as a genuine guest, on the same terms as any other family visitor, is unlikely to fall foul of the rule. Regular exclusive use, or use without consideration in circumstances where a third party would pay, brings the asset back into the estate. The line is fact-sensitive and worth checking before assuming.

Life interest trusts can play a useful role, particularly for blended families or where a surviving spouse needs to remain in the family home. On the first death, the deceased’s share passes into a trust giving the survivor the right to live there for life, with the remainder passing to chosen beneficiaries. This is not a GROB because the survivor is not the person who made the gift — the deceased is. The arrangement is respected as an interest in possession trust and taxed accordingly. Our note on estate administration explains how trusts interact with the wider administration process, and where the family home is disputed it may become part of a contested wills claim.

Planning around the family home in 2026

There is no single right answer to IHT planning for the family home. The £175,000 residence nil-rate band and £325,000 nil-rate band, transferable between spouses, mean many estates below £1 million pay no IHT on the home. For larger estates the £2 million taper erodes the RNRB by £1 for every £2 above, so it is fully lost at £2.35 million per person.

Executors dealing with an estate that includes historic gifts should be alert to potential GROB issues when completing the IHT400. The rules on executor duties require full disclosure of gifts made in the seven years before death, and flag gifts with reservation. Where an intestacy applies, the same disclosure obligations bind the administrators — see our note on intestacy. General guidance is at gov.uk/inheritance-tax, and our full inheritance tax hub collects our detailed guides in one place. You can also browse the wider probate service overview for related topics.

Gifts with reservation of benefit remain one of the costliest inheritance tax mistakes we see. If you or an elderly relative have transferred a property, a valuable asset, or a share of a business while continuing to benefit from it, we would strongly recommend a review before it becomes an executor’s problem. The probate application fee rises to £526 from 13 July 2026, but the wider tax and administration cost of an unplanned GROB will dwarf that many times over.
