A Comparison of Discretionary Trust Variants for Property Estate Planning

22 March 2006 is the structural cut-over date that most discretionary-trust content elides. Before that date, lifetime interest-in-possession settlements sat in their own IIP regime with a distinct (and lighter) tax profile. From 22 March 2006 onwards, FA 2006 Schedule 20 moved nearly all new lifetime settlements into the relevant property regime in IHTA 1984 ss.58 to 85, regardless of whether they are genuinely discretionary or technically IIP. The post-2006 "discretionary trust" label now covers a class of structurally different settlements: the standard lifetime trust with CLT entry, the will-trust with s.144 read-back, the bereaved-minor trust with concessionary treatment, the 18-to-25 trust, the disabled person's interest, and (until 30 October 2024) the multi-pilot-trust planning that the Rysaffe Trustee Co v IRC [2003] EWCA Civ 356 case validated. Each variant has a different IHT, income-tax and CGT profile, and the choice between them shapes the operational picture for the next 30 years of trust life.

This page compares the variants. For the structural comparison between trust vehicles and corporate vehicles (the FIC question), see FIC vs discretionary trust for property.

The FA 2006 cut-over and the relevant property regime

Before 22 March 2006, a lifetime interest-in-possession trust was outside the relevant property regime. The IIP holder was treated for IHT purposes as owning the underlying property. The trust was light: no 10-year periodic charge, no proportional exit charge, no CLT-style entry charge for the settlor (the transfer was a Potentially Exempt Transfer that fell out of the estate if the settlor survived 7 years).

FA 2006 Schedule 20 closed that route. From 22 March 2006, new lifetime IIP trusts fall into the relevant property regime by default. The narrow surviving qualifying-interest-in-possession categories (under amended IHTA 1984 s.49) are: Immediate Post-Death Interests (IPDIs created by will), Disabled Person's Interests (DPIs under s.89 to s.89B), and Transitional Serial Interests (TSIs, narrowly defined). Everything else lifetime is relevant property.

The relevant property regime sits in IHTA 1984 ss.58 to 85. The structural mechanics:

• Entry: CLT. A lifetime gift into the trust is a chargeable lifetime transfer. The IHT rate is 20 per cent on the value above the available NRB, with 7-year cumulation against prior CLTs. If the settlor dies within 7 years the rate steps up to 40 per cent (with taper relief and a credit for the 20 per cent already paid).
• 10-year periodic charge. IHTA 1984 s.64 charges relevant property at each 10-year anniversary at the rate calculated under ss.66 to 67. The maximum effective rate is 6 per cent of trust value, derived as 30 per cent of the assumed-chargeable-transfer rate scaled by complete quarters.
• Exit (proportional) charge. IHTA 1984 s.65 charges capital leaving the settlement between 10-year anniversaries on a pro-rata basis of the next-anniversary rate.

The category label "discretionary trust" in post-2006 conversation covers any new lifetime settlement that sits in the relevant property regime, whether it operates discretionarily or has fixed interests. Pre-2006 trusts retain their pre-existing regime unless restructured. The cut-over date is the single most important framing point in any discretionary-trust conversation: a "20-year-old discretionary trust" set up in 2002 has a very different tax profile from one set up in 2008, even if the trust deeds are nearly identical.

The seven variants

The variants a property estate planner is likely to choose between:

1. Standard lifetime discretionary trust

The default vehicle for lifetime gifting into trust. Discretionary by design (trustees have power to distribute capital and income among a class of beneficiaries). Relevant property regime. CLT entry. 10-year and exit charges. Settlor-interested if the settlor or settlor's spouse can benefit (with ITTOIA 2005 s.624 income attribution and TCGA 1992 s.169E settlor definition for the s.260 holdover restriction).

Suits: lifetime gifting where the settlor wants flexibility on distribution timing and beneficiary class, accepts the 20 per cent entry charge on the slice above NRB, and is comfortable with the rolling 10-year charges. A typical case: a founder running a successful property portfolio gifts £500,000 of growth-share equity into a trust for adult children, paying £35,000 CLT (20 per cent on the £175,000 above the available NRB after lookback), with the trust then growing for the next 30 years inside the relevant property regime.

2. Discretionary will trust

Same trust mechanics as a standard lifetime trust, but created by will on death rather than by lifetime declaration. The death event is itself a chargeable transfer at 40 per cent above NRB, with the full NRB available against the estate. The trust enters the relevant property regime from the date of death.

The differentiator is IHTA 1984 s.144: where the trustees distribute property out of the trust to a beneficiary within 2 years of the deceased's death, the distribution reads back to the deceased as if made directly. A distribution to a surviving spouse within 2 years gets the s.18 spouse exemption retroactively. A distribution to a charity within 2 years gets the charity exemption. A distribution to children at the right value can be structured to use a transferable NRB or to optimise the RNRB. The will-trust + s.144 read-back is the most flexible post-death planning vehicle in the IHT toolkit.

Suits: testators who want to keep options open at the time of will-drafting, knowing the family circumstances at death cannot be predicted. The trustees pick the optimal distribution within the 2-year window. The trade-off is that any property left in the trust after the 2-year window enters the relevant property regime with full 10-year and exit charges.

3. Pilot trust strategy (constrained post-30 October 2024)

The historical Rysaffe Trustee Co v IRC [2003] EWCA Civ 356 planning: a settlor creates several small NRB-sized trusts (each below the relevant property regime entry rate by virtue of the NRB shelter), with each trust treated as having its own allowance for 10-year periodic charge purposes. The strategy allowed the settlor to multiply the NRB across (say) five small trusts of £325,000 each, settling £1.625 million into trust at 0 per cent CLT entry rate.

FA 2026 closes this route for new trusts settled on or after 30 October 2024 (the Autumn Budget 2024 announcement date). Same-settlor lifetime trusts from that date share a single combined APR + BPR 100 per cent relief allowance under IHTA 1984 s.124D (£2.5 million per s.124D(2)(a) as inserted by FA 2026 Schedule 12 paragraph 4). For non-APR / non-BPR property the NRB-multiplication via multiple pilot trusts is also constrained by the anti-fragmentation regime: a same-settlor cohort of trusts is treated as a single planning vehicle for cap purposes.

The strategy is preserved for trusts settled before 30 October 2024. Founders who used pilot trusts in the 2010s and earlier may retain a structurally favourable position. For new planning from 30 October 2024 onwards, multi-pilot-trust strategies need to be tested against the new same-settlor anti-fragmentation framework.

4. Bereaved-minor trust (s.71A)

IHTA 1984 s.71A creates a concessionary regime for trusts left by a deceased parent for the parent's own minor children, where the children take absolute entitlement at 18. The BMT regime is outside the relevant property regime:

• No entry charge (the death is the chargeable event, but the trust itself does not attract a separate CLT or relevant property entry).
• No 10-year periodic charges.
• No exit charges on distributions to the minor children at or before 18.
• Capital must vest absolutely at 18; the trust cannot defer past that age.

The eligibility is narrow. The trust must be created by the will of the deceased parent (or by intestacy in the parent's estate). The beneficiaries must be the deceased parent's own children. A grandparent-to-grandchild discretionary trust does NOT qualify (the children are not the deceased's own children).

Suits: estate planning by parents of minor children. The standard case is a will-side discretionary trust drafted with s.71A eligibility built in, ensuring the trust gets the concessionary treatment if the parent dies before the children reach majority. The 18 vesting age is the limit; later vesting requires the 18-to-25 variant.

5. 18-to-25 trust (s.71D)

IHTA 1984 s.71D extends the BMT-style concessionary regime to allow capital vesting between 18 and 25. The trust is outside the relevant property regime during the 18-to-25 window, but a proportional exit charge applies on distributions or on vesting between 18 and 25, calculated by reference to the period between the child's 18th birthday and the actual vesting date.

The eligibility is the same parent-to-own-child-on-death framework as the BMT. Suits: parents who want to delay capital vesting beyond 18 for maturity reasons but accept the small exit charge that applies. The exit charge is modest (maximum effective rate around 4.2 per cent for a 25-year-old vesting, less for earlier vesting), and the planning benefit of keeping capital in trust until 25 often outweighs the cost.

6. Disabled person's interest (s.89 / s.89B)

IHTA 1984 s.89 and s.89B create a qualifying interest in possession for a trust where the principal beneficiary is a disabled person (broadly: a person whose mental capacity is impaired or a person receiving certain disability benefits). The DPI is outside the relevant property regime: it is treated as a qualifying interest in possession, with the disabled person treated for IHT purposes as owning the underlying trust property.

The structure attracts:

• No CLT entry charge (the lifetime gift is a Potentially Exempt Transfer that drops out of the estate if the settlor survives 7 years).
• No 10-year periodic charges.
• No exit charges.
• The disabled person's death is the chargeable event (the trust property is treated as part of their estate).

Suits: parents or grandparents planning for a disabled adult child. The DPI provides the standard discretionary-trust flexibility (trustees control distribution) with the qualifying-interest-in-possession tax profile, but only where the eligibility criteria for the disabled person are met. Care must be taken with the means-tested-benefits position of the disabled person; specialist advice often needed.

7. Charitable discretionary trust

A discretionary trust whose beneficiaries are exclusively charities (or charitable purposes). Outside the relevant property regime by virtue of full IHT exemption under IHTA 1984 s.23:

• No entry charge (lifetime gift exempt under s.23; death legacy exempt under s.23).
• No 10-year periodic charges.
• No exit charges on distributions to charitable beneficiaries.

Suits: testators with a philanthropic intent and tax-efficient charitable giving objectives. The 36 per cent reduced IHT rate under IHTA 1984 Schedule 1A applies where 10 per cent or more of the net estate passes to charity, layering with the charitable trust structure on the rest of the estate. The 36 per cent reduced rate page walks the operational mechanic.

Entry-tax profile compared

The entry charge is the first cost the settlor faces. Across the variants:

• Standard lifetime discretionary trust: 20 per cent CLT on the slice above available NRB (with 7-year cumulation lookback against prior CLTs). The standard expected entry cost for a lifetime gift of £1 million into trust with no prior CLTs is £135,000 (20 per cent on £675,000 above the NRB), grossed up if the settlor pays the tax.
• Discretionary will trust: 40 per cent death rate above NRB on the estate (NRB and transferable NRB available; RNRB if direct-descendant residential property is involved at distribution; spouse exemption if read-back applied to surviving-spouse distribution under s.144). The trust itself does not attract a separate entry charge; the entry is the death.
• Bereaved-minor trust (s.71A): Entry is the death event at 40 per cent above NRB. No additional trust-side entry charge.
• 18-to-25 trust (s.71D): Same as BMT entry profile (death event, no additional trust-side charge).
• Disabled person's interest (s.89): Lifetime gift is a PET (drops out of estate if settlor survives 7 years). Death gift gets the spouse exemption if applicable, then 40 per cent on the slice above NRB attributable to the DPI.
• Charitable discretionary trust: No entry charge (s.23 IHTA 1984 exempt).

10-year periodic charge profile compared

The 10-year periodic charge is the major ongoing cost for relevant property settlements. The maximum effective rate is 6 per cent at each anniversary, derived as 30 per cent (the assumed-chargeable-transfer rate) scaled by the proportion of complete quarters in the 10-year period. Across the variants:

• Standard lifetime discretionary trust: Yes. Up to 6 per cent at each 10-year anniversary. On a £1 million trust, the ceiling at each anniversary is £60,000, though the effective rate is typically lower in early years where the cumulative chargeable transfers stay below the rate-determining threshold.
• Discretionary will trust: Yes, for property still in the trust after the 2-year s.144 read-back window has closed. Distributions within the 2-year window read back to the deceased and the property does not enter the relevant property regime.
• Pilot trust (pre-30-October-2024 cohort): Yes, with each pre-2024 pilot trust enjoying its own allowance for the rate calculation (the Rysaffe benefit).
• Pilot trust (post-30-October-2024 cohort): Yes, with the same-settlor cohort sharing a single allowance under the anti-fragmentation rule (the Rysaffe benefit closed).
• Bereaved-minor trust (s.71A): No. Outside the relevant property regime.
• 18-to-25 trust (s.71D): No 10-year charge during the 18-to-25 window. A proportional exit charge applies on vesting between 18 and 25.
• Disabled person's interest (s.89): No. Treated as qualifying interest in possession.
• Charitable discretionary trust: No. s.23 exempt.

Settlements legislation: s.624 and s.629 attribution

The settlements legislation in ITTOIA 2005 Part 5 Chapter 5 (ss.620 to 628) attributes trust income back to the settlor in two scenarios:

• s.624: settlor-interested settlement. Where the settlor or the settlor's spouse retains an interest in the settlement (broadly: can benefit, even contingently). The trust income is taxed on the settlor as if it were the settlor's own income. The standard lifetime discretionary trust hits this trap if the settlor or spouse is included in the discretionary class. The spouse carve-out under s.626 (the Jones v Garnett (Arctic Systems) [2007] UKHL 35 line) does not apply to discretionary trusts; it relates to outright gifts between spouses of income-producing assets.
• s.629: minor-child attribution. Where the settlor is the parent and the beneficiary is the settlor's own minor child (under 18 and unmarried). Trust income arising and distributed (or accumulated) to or for the benefit of the child is attributed to the settlor. A £100 de minimis under s.629(3) applies. The attribution sunsets on the child's 18th birthday.

The variant-by-variant settlor-interested position:

• Standard lifetime discretionary trust: Settlor-interested if the settlor or settlor's spouse is in the discretionary class. The s.624 trap is the single most common avoidable mistake in lifetime trust planning. Most discretionary class definitions intended for adult-children planning should explicitly exclude the settlor and the settlor's spouse to avoid the trap.
• Discretionary will trust: Not settlor-interested (the settlor is dead). s.624 cannot bite.
• Bereaved-minor trust (s.71A): Not settlor-interested (the settlor is the deceased parent; s.629 cannot bite because the settlor is dead).
• 18-to-25 trust (s.71D): Same position as BMT.
• Disabled person's interest (s.89): Settlor-interested where the settlor is alive and the disabled person is the settlor's spouse or settlor (rare); not settlor-interested where the disabled person is the settlor's adult child (the standard case).
• Grandparent-route trust (grandparent settles for grandchild): Not subject to s.629 minor-child attribution because the settlor is not the parent of the minor beneficiary. The s.629 framework is parent-specific.

For the operational depth on settlor-interested trust mechanics, see the settlor-interested trust deep page.

CGT holdover (s.260) compared

TCGA 1992 s.260 gives full CGT holdover on a CLT entry into a non-settlor-interested discretionary trust. The settlor's capital gain on the gifted asset is rolled into the trustees' base cost, deferring the CGT until the trustees dispose. The holdover is denied for settlor-interested trusts under TCGA 1992 ss.169B to 169G (with s.169E defining settlor for these purposes per the F-4 lock).

Across variants:

• Standard lifetime discretionary trust, non-settlor-interested: s.260 holdover fully available. The settlor's gain rolls into the trustees' base cost.
• Standard lifetime discretionary trust, settlor-interested: s.260 holdover denied. The settlor pays CGT on the gift at the lifetime gift's deemed market value.
• Discretionary will trust: No CGT on death (TCGA 1992 s.62 uplift). The trustees take a new base cost at the date-of-death value. s.260 holdover is available on subsequent distributions out of the trust if those distributions are themselves chargeable transfers (e.g. exit charges).
• Bereaved-minor trust (s.71A): Same as will trust (no CGT on death entry; s.260 available on distributions if relevant).
• Disabled person's interest: Lifetime gift is a PET; no CGT holdover available on a PET (PETs are not chargeable transfers; s.260 requires a chargeable transfer). The settlor pays CGT on the gift unless other relief (s.165 trading-asset gift relief if the asset qualifies) applies.
• Charitable trust: s.260 fully available; in practice the gift is exempt for both IHT (s.23) and CGT (s.257) on transfer to a charity.

The Patel family worked example: three scenarios, three variants

The Patel family owns a £2 million property portfolio (5 BTL houses across the Midlands) in personal names. They have two adult children (28 and 31) and a younger child (15). The parents are in their late 50s, both UK-resident, both LTR for IHT purposes. They want to start estate planning. Three distinct scenarios, three variant choices:

Scenario A: lifetime gift to children's discretionary trust while founder is alive (£500k slice). The Patels want to gift £500,000 of equity (held via growth shares in a newly-incorporated SPV) into a trust for their adult children, with the trust holding the growth shares for 30 years and the parents retaining their CT-paying portfolio. Variant: standard lifetime discretionary trust, non-settlor-interested. The discretionary class includes the two adult children and the younger child (when she turns 18), explicitly excludes the parents and any future spouse of the parents. Entry: CLT at 20 per cent on the £175,000 slice above the £325,000 NRB (£35,000). 10-year periodic charges from the date of declaration. s.260 holdover available on the CGT on the share transfer (rolls the settlor's gain into the trustees' base cost). s.624 settlor-interested trap avoided by the explicit exclusion. Result: tax-efficient lifetime structure that removes the growth-share equity from the parents' estate and gives the trustees 30 years to compound the value.

Scenario B: post-death will trust for the family on second death (£2m residue). The Patels' wills leave the residue of the second-to-die's estate into a discretionary will trust for the children and grandchildren. Variant: discretionary will trust with s.144 read-back built in. The trustees have 2 years from the second death to evaluate the family circumstances and distribute (or not) accordingly. If the surviving spouse outlives the first by 5 years and dies with the £2 million residue, the trustees can distribute within the 2-year window to take advantage of read-back; or hold the property in trust for the next generation if the family circumstances suggest. Entry: 40 per cent death rate above the available NRB and transferable NRB (£650,000 combined), so £540,000 IHT on the £1,350,000 above the combined NRB (no RNRB available if the property is investment portfolio not occupied as a residence by the deceased). The s.144 read-back gives the trustees option value.

Scenario C: minor child guardianship trust (£300k slice for the 15-year-old). If both parents were to die while the youngest is still a minor, a £300,000 slice is intended to provide for the youngest's education and welfare to 18 with vesting then. Variant: bereaved-minor trust under s.71A, drafted into both wills as a sub-trust of the residuary will trust. The BMT is parent-to-own-child compliant (eligibility met). No 10-year periodic charges. No exit charge on distributions to the minor at or before 18. Vesting at 18 absolute. Alternative: if the parents prefer vesting at 25 for maturity reasons, the 18-to-25 trust under s.71D applies, with a small proportional exit charge for the 18-to-25 years.

The Patel example illustrates a common pattern: different variants are selected for different slices of the same estate, structured as nested sub-trusts within the overall estate plan. Variant choice is asset-by-asset and circumstance-by-circumstance, not estate-wide.

The s.48ZA LTR test and offshore discretionary trusts

FA 2025 replaced the pre-FA-2025 domicile-based excluded-property test with a residence-based test. IHTA 1984 s.48ZA pivots the excluded-property status of offshore-situs property held in a discretionary trust on the settlor's long-term resident status at the relevant transfer date. The structural change:

• Pre-FA-2025: excluded-property status depended on the settlor's domicile at the date of trust creation. A non-domiciled settlor could create an offshore discretionary trust with overseas assets and shelter the trust property indefinitely from UK IHT, even if the settlor later became domiciled.
• Post-FA-2025 (from 6 April 2025): excluded-property status depends on the settlor's LTR status at the date of each chargeable event. A settlor who is LTR at the relevant 10-year anniversary, exit, or addition-of-property date does not get excluded-property treatment for that event. The status is dynamic, not fixed-at-creation.

The effect on the landlord-emigrant cohort: founders who emigrate from the UK and intend to use offshore discretionary trusts to shelter post-emigration wealth need to test the LTR status carefully. Trusts created during a settlor's UK-resident-and-LTR period attract excluded-property test failure when the trust property is offshore. The excluded-property trust LTR pivot page walks the operational mechanic in detail.

Trust Registration Service compliance

Almost all express trusts are registrable under MLR 2017 reg 45 (SI 2017/692). The deadlines:

• New trusts: 90 days from creation.
• Trusts that become taxable (paying IHT, income tax or CGT): 90 days from the chargeable event.
• Annual update where data changes (trustees, beneficiaries, assets).

The penalty for non-registration is a case-by-case discretionary fine of up to £5,000 per HMRC TRSM80020 guidance. The graduated tariff that some practitioner content cites (£100, £200, £300 escalation) is a misconception; the operative position is the single £5,000 maximum applied on case facts. Trustees register online via the HMRC Trust Registration Service portal. For trust-owned BTL portfolios, the TRS compliance for trust-owned BTL page walks the registration steps.

Variant decision matrix

A condensed decision matrix for the property-estate-planning context:

• Founder alive, adult children, lifetime gifting: standard lifetime discretionary trust, non-settlor-interested. CLT entry, 10-year and exit charges. s.260 holdover on CGT.
• Founder alive, minor own children, lifetime gifting: avoid the s.629 settlor-interested attribution by grandparent-route structuring, or accept the attribution and plan for the child's 18th birthday.
• Founder deceased, residue into trust for family: discretionary will trust with s.144 read-back option. Maximum post-death flexibility.
• Founder deceased, minor own children: bereaved-minor trust under s.71A (vesting at 18) or 18-to-25 trust under s.71D (vesting between 18 and 25).
• Founder alive, disabled adult-child planning: disabled person's interest under s.89 (qualifying interest in possession, outside relevant property regime).
• Founder with philanthropic intent: charitable discretionary trust under s.23 (full IHT exemption), often combined with the 36 per cent reduced rate planning on the residue.
• Founder with offshore property and emigration plans: s.48ZA LTR test analysis required; excluded-property trust LTR pivot.
