Section 102 of the Finance Act 1986 is the IHT anti-avoidance rule that catches the most common piece of bad amateur estate planning on property: gift your house to your children, carry on living in it, hope the seven-year clock runs the gift out of your estate. The rule says no. The property remains in your estate at its open-market value at the date of death, the gift was ineffective for IHT, and many years of planning are wasted. This page walks through the statute subsection by subsection, sets out the escape routes that do work (paying full market rent, the narrow Schedule 20 paragraph 6 co-ownership carve-out, the cessation-of-reservation PET under s.102(4)), explains where Pre-Owned Assets Tax steps in as the back-stop when s.102 does not bite, and applies the framework to the standard BTL portfolio gift.

For the planning context (when this matters, where it fits in the wider mitigation menu, the cost of getting it wrong), the sister page is the IHT Decision Framework for UK Landlords. The CGT side of any property gift, which runs in parallel to the IHT analysis here, is at CGT on Gifting Property to Family Members.

The statute in one paragraph: what s.102 actually does

Section 102 Finance Act 1986 applies to gifts of property made on or after 18 March 1986. A gift is "subject to a reservation" where either of two conditions is met during the relevant period (defined as the seven years ending with the donor's death, or the period from the gift to death if shorter):

  • s.102(1)(a): The donee does not assume bona fide possession and enjoyment of the property at or before the beginning of the relevant period.
  • s.102(1)(b): At any time during the relevant period the property is not enjoyed to the entire exclusion, or virtually to the entire exclusion, of the donor and of any benefit to him by contract or otherwise.

The consequence under s.102(3): property subject to a reservation immediately before death is treated for IHT purposes as property to which the donor was beneficially entitled immediately before death. It falls into the estate at its open-market value at the date of death. The lifetime gift, however dutifully documented, does not lift it out.

The carve-outs (s.102(5)) and the cessation-PET (s.102(4)) are the two routes back to a clean gift, and the rest of the page walks through them. Section 102(8) cross-references Schedule 20 FA 1986, which contains the supplementary provisions including the para 6 co-ownership rule.

What "reservation of benefit" actually covers

Two phrases in s.102(1)(b) carry the analytical weight: "entire exclusion, or virtually to the entire exclusion" and "any benefit to him by contract or otherwise". The combined effect is broad.

HMRC's reading, set out across IHTM14301 to IHTM14400, treats almost any continuing connection between the donor and the gifted property as a reservation. Continued occupation (the classic case). Continued receipt of rents (where the donor lets the gifted property and takes the income). Use as a holiday home. A right to occupy reserved in the deed of gift. An arrangement under which the donor pays nothing and the donee gives the donor a benefit in return for the gift. The "virtually" qualifier picks up arrangements where the donor's reserved benefit is small but is still a benefit.

The flip side: the donee must assume "bona fide possession and enjoyment". A bare legal transfer where the donee receives no actual control, no rents, no day-to-day enjoyment of the asset, fails the s.102(1)(a) limb regardless of what the donor does or does not retain.

The classic trap: a £600,000 home gifted, parents continue to live there

The textbook GROB scenario. The Patel-estate persona: parents in their late 60s, family home in Stockport worth £600,000 at the gift date, two adult children. The parents transfer the legal title to the children in equal shares, intend the gift as a PET, continue to live in the property rent-free, pay the council tax and utilities themselves, and update their wills accordingly.

The parents die eight and nine years later. The property at death is worth £820,000. The children expected the property to be outside the estate (both PET seven-year clocks ran out). HMRC's response: s.102(1)(b) was breached throughout the period. The property was not enjoyed to the entire exclusion of the donors. The reservation was continuous from the date of gift to the date of each death. Under s.102(3) the property is in the deceased's estate at £820,000 (each parent's death is computed on the share of the property they had gifted, with the survivor's death picking up the second half).

The IHT consequence: roughly £820,000 brought back into the estate, against a couple's combined nil-rate band of (typically) £650,000 with full RNRB lost where the gift broke the direct-descendant condition. Tax exposure: in the order of £200,000 to £280,000 that the family thought had been planned away.

The seven-year clock did its work; it simply was the wrong clock. The PET never had effect.

Escape route one: pay full market rent

The clean route through s.102 on a continued-occupation home gift is to pay the donee full open-market rent for the period of occupation. The mechanics:

  • Commercial-rate rent, set against current local lettings comparables for an unfurnished or furnished equivalent property.
  • Documented in a written tenancy agreement (typically an assured shorthold tenancy or a private letting agreement at this scale).
  • Reviewed every two to three years against fresh market evidence and adjusted accordingly. A static rent over a decade of rising local rents looks like a constructive reservation even where the original rent was commercial.
  • Actually paid, with bank evidence (standing order from the donor's bank account to the donee's, monthly).
  • The donee declares the rent as rental income on self-assessment, deducts allowable expenses, and pays income tax at their marginal rate.

What does not work: a peppercorn rent, a £1-a-year rent, a token rent set well below local market. HMRC's enquiry pattern on this is consistent. They compare the rent against contemporaneous lettings evidence (Rightmove archive, ARLA data, valuer reports) and treat any material shortfall as a continuing reservation.

The donor's CGT base cost is unchanged by the rental arrangement; the property having been gifted at deemed market value, the donee's base cost is the gift-date value (see CGT on Gifting Property to Family Members for the donor-side mechanics including the 60-day reporting obligation and the connected-persons rule).

Escape route two: the Schedule 20 paragraph 6 co-ownership carve-out

Paragraph 6 of Schedule 20 FA 1986 provides a narrow carve-out where donor and donee both occupy the property after the gift. The conditions:

  • The donor and the donee both occupy the land after the gift.
  • The donor receives no benefit (other than a negligible one) provided by or at the expense of the donee in connection with the gift.
  • The donor bears their share of the cost of running the property: council tax, utilities, repairs, maintenance, allocated proportionately to use.

Where met, s.102 does not apply to the donor's continued occupation. Practical examples that genuinely work: an adult child moves into the parent's family home (perhaps following a divorce, or to care for the parent), legal title is transferred to the child, both occupy the property thereafter, the parent pays their proportionate share of running costs.

HMRC scrutiny is high. The carve-out fails where the running-cost split is too favourable to the donor, where the donee's "occupation" is nominal (only visits occasionally), or where the donor enjoys an exclusive part of the property (parent uses the principal bedroom and en suite, child has a small back room). The documentary trail (proportionate utility-bill payments, council-tax assessment showing both as residents, contemporaneous records) needs to be solid before any enquiry.

If the donor's co-occupation ends, the carve-out ends. Section 102(4) then operates from the cessation date (see below).

POAT as the back-stop where s.102 does not bite

The Finance Act 2004 Pre-Owned Assets Tax regime (s.84 plus Schedule 15) is the income tax catch for arrangements that escape s.102 but still leave the donor enjoying the property. The canonical case: cash gift route. A donor gifts £500,000 of cash to a child, the child uses the cash to buy a house, the donor moves in rent-free.

Section 102 does not apply: the gift was of cash, not of the subsequent property; the donor never owned the house. POAT does apply: the donor enjoys the property and POAT charges an annual income tax sum based on the deemed market rent of the occupied property, in proportion to the gifted cash contribution to the purchase price.

POAT mechanics:

  • Annual charge: deemed market rent of the property, multiplied by the proportion of the purchase price funded by the gifted cash, taxed at the donor's marginal rate on self-assessment.
  • De minimis: no charge where the annual deemed rent (after proportioning) is under £5,000.
  • Indexation: the deemed rent is re-valued every five years against current market rates.
  • Election out (under paragraph 21 Sch 15 FA 2004): the donor can elect on form IHT500 to be treated as making a GROB instead. The election removes the annual income tax charge but puts the property into the donor's estate for IHT. The election is made by 31 January after the tax year in which POAT first applies and is irrevocable.

The choice between paying POAT and electing to GROB is age-and-survival dependent. For a donor in their early 60s in good health, the long POAT income tax bill (potentially 20+ years of charges) usually exceeds the eventual IHT cost, so the election is often the right move. For a donor in their late 70s with health concerns, the few years of POAT may be cheaper than full IHT on a property in the estate.

Cessation of reservation: the s.102(4) escape and the false-PET clock

Section 102(4) provides that where the reservation ceases before the end of the relevant period, the donor is treated as having made a PET at the moment of cessation. The seven-year clock then runs from the cessation date, not from the original gift.

Application: a donor gifted the family home at age 65, lived there rent-free for the first five years (GROB applying throughout), then moved into residential care at age 70 (reservation ends at the move-out). The deemed PET arises at age 70. The donor must survive to age 77 for the full seven-year PET protection. Where the donor dies before age 77, the deemed PET becomes chargeable; taper relief between years 3 and 7 reduces the tax (s.7(4) IHTA 1984), but the gift comes back into the estate at its open-market value at the cessation date (not the original gift date and not the death date).

The donor's personal representatives report the cessation-PET on form IHT100c where death is within seven years. HMRC reconciles the donor's IHT400 with the IHT100c calculation; double charges relief under the FA 1986 (Double Charges) Regulations 1987 ensures the property is not taxed twice if both the GROB rules and the PET-on-cessation rules would otherwise apply.

GROB and BTL portfolio gifts: when does it bite?

On the standard fact pattern, gifts of BTL property are clean for s.102 purposes. The donor was never the occupier; the donee takes the rents from the date of legal transfer and pays the income tax on them; the donor enjoys no benefit. The PET runs from the gift date in the normal way, and on full seven-year survival the gift falls out of the estate.

GROB does bite on BTL gifts where the facts are non-standard:

  • The donor continues to receive the rents (through a side-letter, an undocumented family understanding, or because the donee has no bank account to receive them). HMRC's enquiry pattern looks at where the rent actually goes; nominal transfer of legal title is not enough.
  • The donor uses the property as a personal holiday home or weekend retreat, even occasionally.
  • The donor retains the right to live in the property (e.g. a clause in the deed of gift reserving a lifetime interest).
  • The donor manages the property and takes management fees that exceed market rate (constructive reservation through over-paid management).

The clean BTL gift fact pattern: legal title transferred to donee, donee receives rents directly from tenant or via the donee's own letting agent into the donee's own bank account, donee declares the rental income on their own self-assessment, donor has no ongoing involvement. Where that pattern is documented contemporaneously, s.102 is not engaged.

For the framing of where BTL gifting sits within the wider planning menu, see the parallel Inheritance Tax on Rental Property Portfolios pillar.

The s.102(5) exemptions and the s.102A to s.102C extensions

Section 102(5) excludes gifts that qualify under specified exempt-transfer provisions of IHTA 1984. The principal exclusions:

  • s.18 IHTA 1984: transfers between UK-resident spouses and civil partners. A gift to a spouse who then allows the donor to continue to occupy is outside s.102.
  • s.20 IHTA 1984: small gifts (£250 per donee per tax year).
  • s.22 IHTA 1984: gifts in consideration of marriage or civil partnership (limits apply: £5,000 from a parent, £2,500 from a grandparent or party to the marriage, £1,000 from anyone else).
  • s.23 IHTA 1984: gifts to qualifying charities.
  • s.24 / 24A IHTA 1984: gifts to qualifying political parties and housing associations.

Sections 102A, 102B and 102C were inserted by FA 1999 to extend the reservation concept to gifts of an interest in land made after 9 March 1999. They catch arrangements where the donor retains a significant right or interest in the land (s.102A), participates in a significant arrangement relating to the land (s.102B), or where the donee makes the property subject to a reservation in favour of the donor (s.102C). For most family-home and BTL-portfolio cases, s.102 itself suffices. The extension provisions come into play with complex shared-ownership, lease-back, and family-trust-into-land structures.

The four most-enquired patterns and how HMRC approaches them

  1. The gift-then-occupy pattern. Donor gifts the family home and continues to live in it rent-free or below-market. HMRC's standard enquiry: request the deed of gift, the tenancy agreement (if any), bank statements showing rent paid, market evidence of comparable lettings. The reservation is established by reference to s.102(1)(b) and the property goes into the estate at death-date market value.
  2. The pre-2003 home-loan scheme. The donor and a related party set up matching trusts holding interests in the home. Most pre-2003 schemes are now caught by POAT under Sch 15 FA 2004, with the donor either paying annual POAT income tax or making the IHT500 election to GROB. HMRC's view, supported in the case law, is that the schemes do not work.
  3. The BTL "gift but I keep the rent" pattern. Donor transfers legal title to a child but continues to bank the rent. HMRC's enquiry traces the actual rent recipient. Constructive reservation is established under s.102(1)(b) regardless of what the legal title shows.
  4. The shared-occupancy carve-out claim. The donor and donee both live in the property and the donor claims the Sch 20 para 6 carve-out without bearing a proper share of running costs. HMRC's enquiry pattern: request council-tax letters showing both as resident, utility bill split, evidence of donor's proportionate cost contributions. The carve-out fails where the contributions don't match the use.

For the wider question of how lifetime gifting fits within an overall IHT plan, including life cover, FIC restructuring, and the post-April-2027 pension picture, the decision-framework counterpart is at An IHT Decision Framework for UK Landlords. Spousal transfers fall outside s.102 entirely (s.18 IHTA 1984); the CGT mechanics on that route are at CGT on Property Transfer to Spouse.
