Settlor-Interested Property Trust: How Three Separate Statutes Each Independently Defeat the Plan

The settlor-interested trap is the single biggest mistake amateur estate-planners make when settling rental property on trust. Three separate UK tax statutes each carry an independent attribution rule that bites when the settlor (or in some cases the settlor's spouse or dependent minor child) can benefit from the trust. Any one of the three, on its own, is capable of defeating a property-trust plan; in the typical "spouse and children as discretionary beneficiaries" drafting that competitor content frequently endorses, all three bite simultaneously. The structure ends up costing the settlor a full income-tax charge on the trust rents, a dry CGT charge on the latent gain at residential rates with no sale proceeds to pay it, and a 20% lifetime IHT entry charge on the value above the nil-rate band, with no offsetting estate-mitigation benefit because the property either remains in the settlor's economic ambit (failing the income-shifting and CGT-deferral tests) or routes back to the surviving spouse on death under a s.49(1A) carve-out (failing the IHT-removal test).

This page walks the three-statute attribution stack in the order the statutes bite (income tax first, CGT second, IHT third), shows three worked failure-mode case studies (caught on all three, probably caught, clean), and sets out the drafting fix (express exclusion of settlor and settlor's spouse from the beneficiary class) plus the five-step unwinding playbook for trusts already in place.

The three statutes at a glance

Three independent attribution mechanisms, each with its own statutory hook, its own trigger test, and its own consequence. The amateur-planner trap is that they are easy to confuse: they all use the word "settlor", they all have spouse and family carve-outs, and the practical fact patterns that trigger them overlap heavily. They are not the same rule and they cannot be analysed as a single rule.

• Income tax: ITTOIA 2005 s.624. Income arising under the settlement is treated for income tax purposes as the income of the settlor and of the settlor alone, where the income arises during the settlor's life and from property in which the settlor has an interest. The retained-interest test is at s.625 and extends to the settlor's spouse or civil partner. Three statutory carve-outs at ss.626 (outright gifts between spouses or civil partners, the Arctic Systems carve-out), 627 (separation, commercial, pension), and 628 (gifts to charities). No carve-out for minor children; the analogue for minor-child distributions is the separate s.629 attribution rule.
• CGT: TCGA 1992 s.169B. Verbatim s.169B(1): "Neither section 165(4) nor section 260(3) shall apply in relation to a disposal made by a person to the trustees of a settlement" where Condition 1 (settlor or settlor's spouse, civil partner, or dependent minor child has, or may acquire, an interest under s.169F) or Condition 2 (chargeable gain has been reduced by an earlier holdover claim and the prior claimant has an interest) is met. Blocks BOTH the s.260 CLT holdover AND the s.165 business-asset holdover. Settlor definition at s.169E (a person is a settlor where the settled property includes property originating from them). "Arrangement" definition at s.169G (includes any scheme, agreement, or understanding, whether or not legally enforceable).
• IHT: IHTA 1984 s.49(1A). Verbatim s.49(1A): for IIPs arising on or after 22 March 2006, the s.49(1) read-through (treating the IIP holder as beneficially entitled to the underlying property for IHT) applies only where the IIP is an immediate-post-death interest (IPDI), a disabled person's interest, or a transitional serial interest, or falls within s.5(1B). The s.49(1A) mechanic is not itself an attribution rule in the same sense as s.624 or s.169B; it operates by carving certain post-2006 IIPs back into the s.49(1) treatment, with the effect that any IPDI for the settlor or settlor's spouse causes the property to sit in the IIP-holder's estate for IHT. Pairs in practice with the parallel FA 1986 s.102 gifts-with-reservation track, which is the substantive IHT add-back mechanism (covered on Wave 6 B5 and B7).

The trap is the trifecta: a discretionary trust naming "spouse and children" as the beneficiary class triggers s.624 (because the spouse is in the s.625 retained-interest test), triggers s.169B (because the spouse is in the s.169F definition of interest of settlor), and may engage s.49(1A) read-through if the trust is later varied to create an IIP for the surviving spouse. None of the three is reduced by the others; each independently denies the planning goal it would have served.

Statute 1: ITTOIA 2005 s.624 (income tax attribution)

s.624(1) is the operative attribution: "Income which arises under a settlement is treated for income tax purposes as the income of the settlor and of the settlor alone if it arises (a) during the life of the settlor, and (b) from property in which the settlor has an interest." Subsection (1A) adds that trustee expenses cannot be used to reduce the attributed income. Subsection (3) cross-refers to the three carve-outs at ss.626, 627, and 628.

The retained-interest test at s.625(1) is broad: "an interest in property" exists where there are any circumstances in which the property or any related property (a) is payable to the settlor or spouse or civil partner, (b) is applicable for the benefit of the settlor or spouse or civil partner, or (c) will, or may, become so payable or applicable. The "in any circumstances" formulation is what makes the test so easy to fail: any discretionary power held by the trustees to benefit the settlor or settlor's spouse, however contingent, brings the trust within s.625.

For landlord pages, the s.624 mechanic means rental income from a BTL property settled on a trust where the settlor (or settlor's spouse) is in the beneficiary class is taxed on the settlor at the settlor's marginal rate, regardless of who the named beneficiaries are or how the trustees actually distribute the income. The income is treated as the settlor's for income tax; the trustees may still hold the cash, but the income-tax liability sits on the settlor. The settlor's self-assessment return must include the trust income; the trustees should provide the settlor with a tax-pool certificate for income that has already borne trust-rate tax at source.

For the full statutory walkthrough of s.624 plus the s.626 spouse carve-out, the Arctic Systems case law context, and the s.629 minor-child analogue, see our Wave 6 B2 companion on the settlements legislation (forthcoming).

Statute 2: TCGA 1992 s.169B (CGT holdover block)

The CGT-side attribution is structurally different from the IT-side. s.169B does not attribute the gain back to the settlor; instead, it disapplies the two holdover reliefs that the settlor would otherwise have claimed. The transfer into trust is still a disposal at market value under TCGA 1992 s.17 (connected-person rule), generating a chargeable gain, but the s.260 and s.165 holdover routes are both closed off, so the gain crystallises immediately on the settlor with no relief.

The full mechanic in s.169B(1): "Neither section 165(4) nor section 260(3) shall apply in relation to a disposal ('the relevant disposal') (a) made by a person ('the transferor') to the trustees of a settlement, and (b) in respect of which Condition 1 or Condition 2 below is satisfied." The blocking of both holdover routes (s.165 business-asset and s.260 CLT) is the load-bearing point. Many competitor pieces treat only s.260 as blocked, leaving readers with the impression that s.165 (business-asset holdover) might be available as a fallback. It is not. For property structures that might be expected to qualify as business assets through an FHL grandfathered claim (post-April-2025) or an active letting trade, the s.165 fallback is also closed.

The two conditions in s.169B(2) and s.169B(3)

Condition 1 at s.169B(2) catches the obvious case: at the moment of the disposal into trust, the settlor (or settlor's spouse, civil partner, or dependent minor child per s.169F) has an interest or may acquire one through an arrangement under s.169G. The Condition 1 test is the one that catches the typical landlord misstep where the settlor draws the beneficiary class wide enough to include themselves or their spouse "in case of need" or "for tax-flexibility reasons".

Condition 2 at s.169B(3) catches an indirect avoidance pattern. A chargeable gain would arise on the relevant disposal, but the allowable expenditure has been reduced in consequence of an earlier s.165 or s.260 claim on a prior disposal by another individual; immediately after the relevant disposal, that earlier individual has an interest in the destination trust or an arrangement subsists under which they may acquire one. Condition 2 closes the route of cascading held-over gains through chains of trusts to land them in a settlor-interested structure at no further CGT cost. Most landlord cases fail at Condition 1, but advisers running multi-trust hold-co structures should test Condition 2 independently.

The s.169F interest test

s.169F defines when an individual has an interest in a settlement for the purposes of ss.169B to 169D. Subsection (2) covers the principal case: any property comprised in the settlement, or derived property, is or will or may become payable to or applicable for the benefit of the individual or spouse or civil partner in any circumstances whatsoever. Subsection (3) covers the benefit case: the individual or spouse or civil partner enjoys a benefit deriving directly or indirectly from settlement property. Subsection (3A) extends the test to dependent minor children of the settlor (defined as unmarried persons under 18, per s.169F(4A) to (4B)).

The "in any circumstances whatsoever" wording in s.169F(2) is the language that makes the test so easy to fail. A discretionary trust where the trustees have power to benefit the settlor, even on the most circumscribed contingency, is caught. A "letter of wishes" that mentions the settlor as a possible beneficiary is caught. A pattern of trustee behaviour suggesting the settlor will benefit is caught.

The s.169E settlor definition (NOT s.169G)

The settlor definition for ss.169B to 169D is at s.169E, not s.169G. s.169E(1): for the purposes of this section and ss.169B to 169D, a person is a settlor in relation to a settlement if (a) the person is an individual, and (b) the settled property consists of, or includes, property originating from them. Subsection (2) defines property "originating from" a settlor as property which the settlor has provided directly or indirectly for the purposes of the settlement, or property which wholly or partly represents that property or any part of it. Subsection (3) includes property provided in pursuance of reciprocal arrangements with the settlor (i.e. cross-settlement structures).

s.169G is a different definition: it defines "arrangement" for the purposes of ss.169B to 169E as including any scheme, agreement, or understanding, whether or not legally enforceable. Older commentary occasionally describes s.169G as the settlor definition; that is an artefact of pre-2009 numbering, when s.169G(2) to (5) held some settlor-related content that was omitted by the Finance Act 2009. The current text is solely the arrangement definition.

Statute 3: IHTA 1984 s.49(1A) (IHT read-through)

The IHT side is structurally the least intuitive of the three. s.49(1A) is not itself an attribution rule; it is a carve-out rule that allows certain post-22-March-2006 IIPs to be treated under s.49(1) (read-through to the underlying property) rather than under the relevant property regime that captures most post-2006 trusts.

The carve-outs at s.49(1A) are: (a) immediate-post-death interests (IPDIs), (b) disabled persons' interests, and (c) transitional serial interests, plus IIPs falling within s.5(1B). Where the IIP is in any of these categories, s.49(1) reads through: the IIP holder is treated as beneficially entitled to the underlying property for IHT, with the consequence that the property sits in the IIP holder's death estate.

The amateur-planner trap on the IHT side is the IPDI for the surviving spouse. A settlor structures the trust so that on the settlor's death an IPDI arises in favour of the surviving spouse (often via a will-trust mechanic intended to give the spouse income for life with capital passing to children on the spouse's death). The IPDI is within s.49(1A)(a). s.49(1) reads through. The trust property sits in the surviving spouse's estate at second death for IHT. The original IHT goal (removing the property from the second-death estate) is defeated by the very carve-out that makes the IIP-for-spouse mechanism work as a lifetime-income vehicle.

The structural fix is to avoid IPDIs for the settlor's spouse on the same property. If the spouse needs income, route it through a separate arrangement (a discretionary trust with the spouse as one of several beneficiaries; a separate insurance-bond or annuity structure outside the trust). The property-holding trust itself should not generate an IPDI for the spouse if the IHT-removal goal is to be preserved.

The IHT add-back via the parallel FA 1986 s.102 gifts-with-reservation track is a different mechanism, covered in detail on our Wave 6 B5 (forthcoming) page on family-home GROB depth. The interaction between settlor-interest and GROB (where both attribution regimes layer onto the same arrangement and produce a structure that is broken on both fronts simultaneously) is the subject of our Wave 6 B7 companion (forthcoming).

Worked case 1: caught on all three (the Wakefield settlement)

Mrs Wakefield, settlor, age 55, in good health, wants to remove a £450,000 BTL property from her estate. Her husband (Mr Wakefield, age 58) and three adult children are the intended beneficiaries. The trust deed names "Mr Wakefield, the children of the marriage, and the grandchildren of the marriage" as the discretionary beneficiary class. The BTL was acquired in 2009 for £230,000 base cost plus £6,900 SDLT plus £1,000 legal fees plus £25,000 of enhancement expenditure across the years = total base cost £262,900. Current market value £450,000. Latent gain £187,100. Annual rental income £20,000 net of allowable expenses (before finance costs; the BTL is unmortgaged).

Income tax side (s.624 / s.625). Mr Wakefield is in the beneficiary class. s.625(1) treats Mrs Wakefield as having an interest in the trust property because circumstances exist in which trust property may become applicable for the benefit of her spouse. s.624(1) attributes the trust's rental income to Mrs Wakefield. The £20,000 annual rent is taxed on Mrs Wakefield at her marginal rate (assumed 40% higher rate): £8,000 of income tax per year, identical to the outcome before the trust was settled. Year 1 income tax cost from the trust route: £0 (no change). Year 1 to 30 income tax cost over the trust life: £0 (no change). Years of income shifting achieved: zero.

CGT side (s.169B(1) Condition 1). The trust is settlor-interested under s.169F because Mr Wakefield (settlor's spouse) is in the beneficiary class and falls within s.169F(2) (trust property may become applicable for his benefit in circumstances). s.169B(1) blocks both s.260 and s.165(4) holdover. The transfer is a TCGA 1992 s.17 deemed-market-value disposal because the trustees are connected persons. The gain of £187,100 is chargeable on Mrs Wakefield at residential rates: assume she is a higher-rate taxpayer, so 24% applies on the full gain after the £3,000 AEA. Chargeable gain £184,100, CGT at 24% = £44,184, payable via the residential property 60-day return. The CGT is a dry charge: no sale proceeds were received by Mrs Wakefield, so the £44,184 must be funded from other sources.

IHT side. The transfer is a CLT into a relevant property discretionary trust. 20% lifetime IHT on the value above Mrs Wakefield's available NRB. Assuming full unused NRB of £325,000: chargeable element £450,000 minus £325,000 = £125,000. Lifetime IHT 20% × £125,000 = £25,000. Paid by the trustees (from settlement cash, if any) or by Mrs Wakefield personally (with the s.5(2) gross-up rule applying). The trust assets remain potentially within the s.49(1A) net if any future variation creates an IPDI for Mr Wakefield; for the moment the property is in a discretionary relevant property trust with no s.49(1A) carve-out applying.

Year 0 total cost: £25,000 (IHT) + £44,184 (CGT) = £69,184. Estate-mitigation benefit: deferred to Mr Wakefield's death-survival of seven years from CLT, with the husband's continuing benefit potential creating significant uncertainty about whether the structure achieves its goal. Income-tax shifting benefit: zero. CGT-deferral benefit: zero. The structure has cost Mrs Wakefield close to £70,000 in entry tax with no offsetting tax-efficiency gain.

Worked case 2: probably caught (the Crawford settlement)

Mr Crawford, settlor, age 60, settles a £400,000 BTL on discretionary trust for his three adult children. He has been advised by a family-friend solicitor to exclude himself and his wife from the beneficiary class expressly, but to include a clause permitting the trustees to "advance capital or income to the settlor in circumstances of exceptional hardship". The intention is to protect against catastrophe (long-term illness, severe financial reverses, divorce settlement requiring liquidity).

The Crawford structure is probably caught as settlor-interested under s.169F. Mark McLaughlin's canonical settlor-interested-trusts piece treats this kind of contingent-benefit clause as engaging s.169F(2)'s "in any circumstances whatsoever" test. HMRC's published practice (Capital Gains Manual CG34700 onwards) takes the same view: a discretionary power to benefit the settlor, however circumscribed by contingency, brings the settlor within the s.625 / s.169F retained-interest tests. The same analysis catches the trust on the income-tax side under s.624 / s.625.

The probable-catch status is the worst kind of status: the structure may pass an HMRC enquiry if the trustees never invoke the exceptional-hardship clause and there is no documentary record of any expectation that they will. But the risk crystallises on inquiry: HMRC may take the s.624 / s.169F position; the trustees and the settlor must then defend on the facts; the cost of the defence (advisory time, documentary review, possible tribunal litigation) is significant; and the underlying tax position if HMRC wins is the Wakefield outcome with retrospective effect. The drafting fix is to remove the exceptional-hardship clause entirely. The family's protection against catastrophe is better routed through a separate retained reserve outside the trust (a cash buffer, an emergency-access pension drawdown line, an insurance-bond ladder) than through a contingent-benefit clause that compromises the trust's tax-efficiency.

Worked case 3: clean (the Patel settlement with the s.169G fix)

Mr Patel, settlor, age 60, in good health, settles a £400,000 BTL on discretionary trust for his two adult children. The trust deed expressly excludes Mr Patel and any spouse or civil partner of Mr Patel from the beneficiary class. The exclusion is documented in the deed itself, not in a side letter, not in trustee guidance. The exclusion is irrevocable. The deed also explicitly addresses the s.169G arrangement risk: it confirms the absence of any scheme, agreement, or understanding under which value will or may route back to Mr Patel by any indirect mechanism. The trustees retain full discretion across the adult children, any future grandchildren, and their issue. The BTL has a base cost of £186,400 (purchase £160,000 + SDLT £4,800 + legal fees £1,600 + enhancement £20,000) and a current market value of £400,000; latent gain £213,600.

Income tax side. No s.624 attribution. Mr Patel is not within the s.625 retained-interest scope (excluded by deed); no spouse is within the class (excluded by deed); no s.169G arrangement exists (confirmed by deed). Trust rental income is taxed at the trust rate of 45% on accumulated income above the standard-rate band, with credit available to beneficiaries on distribution at their marginal rate. Mr Patel pays no income tax on the trust rents going forward.

CGT side. s.169B does not bite (Condition 1 fails because no s.169F interest exists; Condition 2 fails because no prior holdover claim has reduced expenditure). The s.260 holdover is available. The transfer is a CLT triggering the s.260 election: Mr Patel and the trustees jointly elect, the gain of £213,600 is held over into the trust's base cost (trust's new base cost £186,400), Mr Patel pays no immediate CGT.

IHT side. CLT into the relevant property regime. 20% lifetime IHT on £75,000 chargeable element (£400,000 minus £325,000 NRB) = £15,000 paid within six months. No s.49(1A) carve-out engaged (no IIP exists; the trust is purely discretionary). Trust runs under the standard 10-year periodic charge (up to 6%) and exit charge regime described on our existing CLT pillar.

Year 0 total cost: £15,000. Income-tax-shifting benefit: trust rents now taxed in the trust / beneficiaries rather than on Mr Patel. CGT-deferral benefit: £213,600 latent gain rolled into trust base cost rather than crystallised at 24% (approximate value of deferral: £51,000 of avoided CGT, deferred until the trust eventually disposes of the property). Estate-mitigation benefit: property out of Mr Patel's estate from settlement date (CLT, not a PET; no 7-year tail on the property itself, but the £15,000 entry IHT is "paid up front" rather than subject to the 7-year PET risk).

The drafting clause that fixes most cases

The express-exclusion clause is short and sits in the beneficiary-class section of the deed. The wording should:

1. Expressly exclude the settlor from the beneficiary class. Not "the settlor is not a beneficiary at the date of settlement" (which leaves the door open for later addition) but "the settlor is and shall remain excluded from the beneficiary class for the duration of the trust, and no power to add the settlor as a beneficiary may be exercised by the trustees or any other person".
2. Expressly exclude the settlor's spouse or civil partner (and former spouses, and any future spouse if the settlor remarries). The exclusion is for the spouse "for the time being" of the settlor, with the same irrevocability wording.
3. Expressly exclude any dependent minor children of the settlor. This catches s.169F(3A) and prevents the trust failing the dependent-child arm of the s.169F test. Adult children of the settlor can be included in the class; the s.169F test is about minor children only.
4. Expressly address the s.169G arrangement risk. A short paragraph confirming the absence of any scheme, agreement, or understanding under which trust property will or may benefit the settlor or spouse by any indirect mechanism. This is belt-and-braces drafting, but it forecloses a line of HMRC enquiry that would otherwise turn on the parties' actual intentions and any documentary evidence of side arrangements.
5. Avoid any contingent-benefit clauses for the settlor or spouse. No "in case of exceptional hardship" exceptions; no "the trustees may consider providing for the settlor's accommodation if the trust's circumstances permit" exceptions; no "the trustees may take account of the settlor's wishes" formulations that imply a continuing settlor interest. The family's protection against catastrophe must come from outside the trust.

The clause should be reviewed by a trust-tax specialist before signing. Family-friend solicitor work, well-meaning but tax-naive, is the single most common source of settlor-interested drafting failures we see. The cost of an expert review at the drafting stage is in the order of £1,500 to £3,000; the cost of unwinding a settlor-interested trust already in place is typically £15,000 to £30,000 or more, depending on the asset values and the unwinding route chosen.

The unwinding playbook for trusts already in place

Where a settlor-interested trust is already on the books and the settlor wants to retrofit a clean structure, five steps:

Step 1: confirm the diagnosis on each of the three regimes separately. A trust may be settlor-interested on the IT side without being caught on the CGT side, or vice versa, or may be caught on both but at different intensities. Apply the s.624 / s.625 test (with the s.626 spouse carve-out where applicable), the s.169B / s.169F / s.169E / s.169G test (with the Condition 1 and Condition 2 alternatives), and the s.49(1A) carve-out test (looking at whether any IPDI, DPI, or TSI is in place or could arise on a future trigger). Document the diagnosis in writing as the foundation for whatever fix follows.

Step 2: consider a deed of variation to remove the settlor-interest. Where the trust deed permits variation (most modern deeds include a variation power; many older deeds do not), the trustees (with the settlor's consent and beneficiary consent where required) can vary to remove the settlor and settlor's spouse from the beneficiary class and to remove any contingent-benefit clauses. The variation is itself a chargeable event: for CGT, the trustees are treated as making a deemed disposal at market value (TCGA 1992 s.71); for IHT, the variation may trigger an exit charge under IHTA 1984 s.65 if the variation is a "distribution" from the relevant property in a material sense. The cost-benefit analysis must compare the variation-event tax against the future tax saved by the cleaned-up structure.

Step 3: consider an irrevocable exclusion deed. Where the deed allows it, the settlor and spouse can be excluded by a separate instrument (an exclusion deed or release deed) without restructuring the underlying trust. The exclusion takes effect prospectively. Income arising and gains realised before the exclusion remain caught by the s.624 / s.169B / s.49(1A) regimes; income arising and gains realised after the exclusion are clean. The exclusion deed is a useful intermediate route where deed-of-variation is unavailable or too expensive.

Step 4: consider winding up the trust entirely. Where the trust is fundamentally unsuitable and the settlor-interest is structural rather than reformable, the cleanest fix is to distribute the trust assets back out (typically to the named beneficiaries who are not the settlor or spouse) and terminate the trust. The distribution is an exit-charge event for IHT (s.65 proportionate charge on the value distributed) and a deemed-disposal event for CGT on the trustees (with s.260 holdover available only if the post-distribution structure is itself clean, which on a winding-up usually means direct ownership by the recipient beneficiaries). The full unwinding cost on a typical £400,000 trust held for five years is in the order of £20,000 to £40,000.

Step 5: accept the historic settlor-interest and reposition the structure. Some trusts are better kept as imperfect structures than dismantled. Where the underlying assets are illiquid, the unwinding tax cost is prohibitive, or the family's broader planning goals are served by the trust's existence even at the tax cost, accept the s.624 attribution as a permanent feature, re-target the structure's purpose (asset protection, governance, multi-generational control), and design future planning around the imperfection.

Why the s.626 spouse carve-out does not help on the CGT side

ITTOIA 2005 s.626 excludes from s.624 attribution outright gifts of income-producing property between spouses or civil partners, provided Condition A (the gift carries a right to the whole of the income) and Condition B (the property is not wholly or substantially a right to income) are met. The carve-out is the statutory grounding for the Arctic Systems outcome in Jones v Garnett [2007] UKHL 35, where ordinary shares with full dividend rights gifted to a spouse were held outside s.624 by force of s.626.

The s.626 carve-out is income-tax-only. It does not assist on the CGT side: a transfer into a settlor-interested trust where the settlor's spouse is the relevant beneficiary still fails s.169B(1) Condition 1 (the spouse is within the s.169F definition of interest of settlor). The Arctic Systems mechanic works for direct gifts to spouses (which are not transfers into trust at all) and for share-class structures within trading companies (where the gift is of shares, not into a settlement). It does not work to escape the CGT-side block on holdover relief where the structure is itself a trust with the spouse as a beneficiary.

The spousal carve-out's narrowness is one of the most under-appreciated features of the settlements regime. It solves one statutory problem (Arctic Systems income-shifting between spouses) but provides no shelter from the parallel CGT or IHT consequences of the same arrangement. Pages or advisers that treat s.626 as a general "spouse safe-harbour" misread the section.

Why the dry CGT charge problem hits so hard on property transfers

Two structural reasons make the s.169B dry-charge particularly painful for property settlements.

First, residential property typically carries large latent gains by the time landlords get serious about estate planning. A BTL acquired in 2008 for £180,000 and now worth £400,000 carries a £220,000 latent gain. At the 24% residential CGT rate (post-Autumn-Budget-2024, applied to higher-rate taxpayers on residential property gains; see our existing rates page for the full residential CGT rate history), the CGT bill is £52,080 after the £3,000 AEA. For long-held properties acquired in the 1990s or earlier, the latent gain often exceeds the property's original cost; CGT bills of £75,000 to £150,000 on a single transfer are common.

Second, the transfer into trust generates no proceeds. The settlor receives nothing in exchange for the property; the trustees become the new legal owners. The CGT charge under TCGA 1992 s.17 is calculated by reference to the market value at the transfer date (because the trustees are connected persons under TCGA 1992 s.286, transactions with connected persons are deemed to take place at market value regardless of the actual consideration). The settlor's CGT liability of £52,080 (in the example above) must be funded from outside the transferred property.

The settlor's options for funding the dry charge: sell another asset (which itself may trigger a further CGT charge); refinance the BTL before the transfer to extract cash and fund the CGT from the refinance proceeds (with the loan staying in the settlor's personal name, since assignment to the trustees triggers SDLT on the assumed debt at the 5% additional-dwelling-surcharge rate from 31 October 2024); abandon the trust route entirely and look at a PET-to-individuals route (which has the same s.17 deemed-MV mechanic and the same dry-charge problem, but no offsetting s.260 holdover available even on a clean structure because PETs to individuals are not CLT triggers); or look at an FIC value-freeze route (which has its own CGT cost on the growth-share gift, but typically minority-discounted to 20% to 35% of the gross asset value, reducing the bill).

For landlords with large latent gains and limited liquidity outside the property, the dry-charge problem is often the deciding factor against any settlor-interested trust structure. A clean (non-settlor-interested) trust with s.260 holdover deferred avoids the dry charge entirely, which is why the drafting fix described above is so valuable.

Where this page sits in the Wave 6 trusts cluster

This page is the CGT-and-IHT trifecta page for settlor-interested property trusts. Five companion pages address related angles:

• Wave 6 B1 (forthcoming, pillar): Putting Rental Property into a Trust: the IHT + CGT + SDLT three-tax-stack decision. The pillar that sits above this page and frames the trust-route decision at the level of the three taxes simultaneously.
• Wave 6 B2 (forthcoming, statute walkthrough): Settlements Legislation (ITTOIA 2005 ss.620 to 628 and s.629): the deep statutory walkthrough on the income-tax side. This page references s.624 in summary; B2 walks the full statute, the Arctic Systems case law, the s.626 spouse carve-out conditions, and the s.629 minor-child analogue.
• Wave 6 B5 (forthcoming, GROB depth): FA 1986 s.102 and s.102B Family-Home GROB: the parallel IHT add-back mechanism that catches the settlor (or donor in a non-trust context) where they continue to benefit from gifted property. Different statutory hook from s.49(1A); the s.102 / s.102B test is fact-based on actual benefit rather than IIP-classification-based.
• Wave 6 B7 (forthcoming, double-trap): Settlor-Interested + GROB Interaction: the structural overlay where a settlor-interested trust is also caught by FA 1986 s.102. Both attribution regimes bite on the same arrangement and produce a structure that fails on both fronts simultaneously. Includes the unwinding playbook for the double-trap.
• Wave 4 C10 (live): Settling Property into a Discretionary Trust: the 20% Entry IHT. The clean (non-settlor-interested) version of the CLT mechanic with the Patel worked example showing IHT, CGT, SDLT, and projected year-10 periodic charge.
• Wave 6 A10 (live): Trust-Owned SPV Extraction Rules: the Settlor-Interested Trap. The income-tax side of the same s.624 / s.169B / s.49(1A) attribution stack applied to extraction from a trust-owned property SPV.
