SDLT on Trust‑Owned Family Homes and Parental Buy‑to‑Let Purchases

NO VAT
What SDLT applies when trustees buy a home for children and a parent separately buys a buy-to-let?
Introduction
Stamp Duty Land Tax can become complicated where a family home is held in trust for children and a parent later wants to buy another property personally. A common concern is whether the trust-owned home is treated as the parent’s property, whether the parent’s purchase counts as a second home, and whether the trust must pay the higher SDLT rates when it buys a replacement home.
The answer usually depends on who the legal purchaser is, what type of trust is involved, and whether any beneficiary has a present right to occupy the property. In a discretionary trust case, the trustees are normally treated as the purchasers for SDLT purposes, and that can lead to a different result from the parent’s own purchase.
The Question
A separated parent’s former spouse died after having bought out that parent’s interest in the former family home. The property was then settled into a discretionary trust for the couple’s minor children. The surviving parent is neither a trustee nor a beneficiary, but lives in the trust-owned house with the children as their carer.
The trustees now plan to sell the existing trust-owned house and buy another house for the children and their carer to live in. Separately, the surviving parent wants to buy a buy-to-let property personally using inherited funds.
The key questions are:
- What SDLT rates apply when the trustees buy the replacement home?
- What SDLT rates apply when the parent buys a buy-to-let personally?
- Does the fact that the children are under 18 make the parent’s purchase a “second property”?
- Would the answer change if the children were given a life interest or another qualifying right to occupy?
Nick’s Explanation
Nick’s core view was that the trustees and the parent must be looked at separately for SDLT.
In anonymised form, his reasoning was:
“For a discretionary settlement, the trustees are the purchasers and are liable for SDLT on the trust’s acquisition. The children are not the purchasers unless the trust is a bare trust.”
He also explained that trustees buying a dwelling are generally caught by the higher-rates regime for additional dwellings. In this scenario, the trust’s purchase of a replacement home would usually be charged at residential rates with the 5% higher-rates surcharge added.
On the parent’s own purchase, Nick’s view was different. He said, in substance, that living in a house owned by a discretionary trust for the children does not make the parent the owner of that dwelling for SDLT purposes. If the parent personally owns no other dwelling at the end of the purchase, the buy-to-let would normally be taxed at the standard residential rates rather than the higher rates.
He added that the children being under 18 does not, by itself, cause the trust property to be attributed to the parent.
Nick also identified one possible point of change. If the trust structure were altered so that a beneficiary had a qualifying interest in possession or a genuine right to occupy, Schedule 4ZA may in some cases allow a “look-through” approach when testing the higher-rates rules and any replacement of main residence exception. That would need careful structuring and evidence.
The Law
The main statutory provisions are in the Finance Act 2003.
Section 55 sets out how SDLT is calculated. Table A applies to residential property. Table B applies to non-residential or mixed property.
Section 116 defines residential property, which includes a dwelling and its garden or grounds.
Section 85 and Schedule 16 deal with trustees and confirm that, for SDLT purposes, the trustees are treated as the purchasers in the case of a settlement.
Section 55(4A) points to Schedule 4ZA, which modifies the normal residential rate rules for higher rates on additional dwellings and certain purchases by non-individuals, including trustees in relevant cases.
Section 75ZA imposes the 2% non-resident surcharge where a transaction is a non-resident transaction.
The key legal point is that a discretionary trust is not treated in the same way as a bare trust. In a bare trust, the beneficiary may effectively be treated as the purchaser. In a discretionary trust, the trustees are normally the purchasers for SDLT.
Schedule 4ZA contains the higher-rates rules. Those rules often apply to trustees acquiring residential property. There are also specific rules for certain settlements where a beneficiary has a qualifying interest, such as an interest in possession or a right to occupy. In those cases, the legislation may require the analysis to focus on the beneficiary’s position rather than simply the trustees’ position.
Analysis
The easiest way to analyse this is to separate the trust purchase from the parent’s personal purchase.
First, the trust’s replacement home.
The dwelling being bought by the trustees is residential property, so section 55 Table A is the starting point. Because the purchaser is a settlement trust, Schedule 4ZA must then be considered. In a straightforward discretionary trust case, trustees buying a dwelling are generally within the higher-rates regime. That means the residential rates are increased by the 5% surcharge.
The usual “replacement of only or main residence” exception is mainly designed for individuals replacing their own home. A discretionary trust with no beneficiary who has a present qualifying right to occupy will often struggle to use that exception. So where trustees sell one trust-owned family home and buy another, the higher rates commonly still apply.
Second, the parent’s own buy-to-let purchase.
The parent is not a trustee, not a beneficiary, and has no ownership interest in the trust-owned dwelling. Merely living in the trust property with the children does not make the parent an owner for SDLT purposes. There is no general rule in Schedule 4ZA that attributes a child’s trust property to the parent simply because the children are minors.
That means the parent’s personal purchase is tested by reference to the parent’s own property interests. If, at the end of the effective date of the transaction, the parent owns no other dwelling, the buy-to-let would usually be that parent’s only dwelling for SDLT purposes. In that situation, the higher-rates surcharge should not apply, even though the property is intended to be let rather than occupied by the buyer.
That point often surprises people. A buy-to-let is not automatically charged at higher rates. The surcharge depends on whether the buyer already owns another dwelling and whether the statutory conditions in Schedule 4ZA are met.
Third, the fact the children are under 18.
That fact alone does not alter the parent’s SDLT position. The legislation contains spouse and civil partner attribution rules in some circumstances, but there is no broad rule that treats a child’s dwelling, or a trust-owned dwelling for a child, as though it were owned by the parent.
Fourth, whether giving the children a life interest would change matters.
Potentially, yes, but mainly for the trust’s purchase rather than the parent’s purchase. If a beneficiary has a qualifying interest in possession or a genuine right to occupy, Schedule 4ZA may permit a look-through analysis. In principle, that can affect whether the higher rates apply and whether a replacement of main residence exception is available. But this depends on the exact trust drafting, the nature of the beneficiary’s rights, and whether the old and new properties are in truth the beneficiary’s only or main residence for the purposes of the legislation.
It is not enough simply to describe the arrangement as a life interest. The legal rights created by the trust instrument matter.
Finally, if there is any suggestion that the property being acquired is not suitable for use as a dwelling, that argument must now be approached with caution. The threshold is relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. A property will not fall outside the residential rules merely because it needs repair, modernisation, or substantial works. There must be a much stronger case that it is genuinely not suitable for use as a dwelling at the effective date.
Outcome
On the facts described, the practical outcome is likely to be as follows:
The trustees’ purchase of the replacement family home is likely to be a residential transaction charged under section 55 Table A, with the 5% higher-rates surcharge applying through Schedule 4ZA.
The parent’s personal purchase of a buy-to-let is likely to be charged at the standard residential rates only, provided the parent does not personally own another dwelling at the end of the transaction.
The children being under 18 does not, by itself, make the parent’s purchase a second-home purchase.
Granting a beneficiary a life interest or another qualifying right to occupy could change the SDLT analysis for the trust, but only if the trust structure and the facts satisfy the technical conditions in Schedule 4ZA.
Practical Steps
Anyone in this position should work through the following points before exchange or completion:
Confirm the exact trust type. Check whether the arrangement is truly a discretionary settlement, a bare trust, or a trust with an interest in possession.
Review the trust deed carefully. The SDLT result can turn on whether any beneficiary has a present right to occupy, an interest in possession, or only a discretionary expectation.
Identify the legal purchaser for each transaction. The trustees’ purchase and the parent’s purchase must be analysed separately.
List all dwellings personally owned by the parent at the effective date. The higher-rates test for the personal purchase depends on the parent’s own interests, not merely where the parent lives.
Consider whether any replacement of main residence argument is realistically available to the trust. In a discretionary trust without qualifying beneficiary rights, it often is not.
Check residence status for SDLT purposes. If the trustees or the individual buyer are non-resident under section 75ZA, the 2% surcharge may also apply.
If the trust structure may be changed, obtain drafting advice before any variation. A supposed life interest that is not properly created may not achieve the SDLT result expected.
If there is any thought of claiming the property is not suitable for use as a dwelling, test that position against the stricter approach confirmed in Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.
Conclusion
Where a home is owned by a discretionary trust for children, the trustees are usually the purchasers for SDLT and their replacement purchase will often attract the 5% higher-rates surcharge. By contrast, a parent who lives in that trust-owned home but has no ownership interest in it will not usually be treated as owning it for SDLT. If that parent then buys a buy-to-let and owns no other dwelling personally, the standard residential rates will usually apply instead of the higher rates.
