SDLT planning in Kenton: the family-property purchase where parents pay the surcharge that the child should have paid

Kenton's demographic mix produces a specific SDLT pattern that the area's family-based ownership culture makes unusually common: parents buying a flat, usually in the £280,000–£420,000 range, for an adult child to live in. The default SDLT treatment assumes the parents are the purchasers, and because they already own their main home, the 5% additional-dwelling surcharge applies to the entire purchase price. On a £380,000 Kenton flat, that surcharge is £19,000 — paid by the parents at completion, on top of the standard SDLT of roughly £9,000. The assumption is rarely questioned by the conveyancer. It should be.

HMRC's position, set out in SDLTM09815 and the surrounding manual guidance, is that where a property is held under a bare trust — legal ownership vested in trustees, absolute beneficial ownership in a single adult beneficiary — the SDLT purchaser is treated as the beneficial owner, not the trustees. In a properly structured bare trust where the adult child is the sole beneficial owner (and the parents are trustees only, or where the child takes legal title directly with the parents providing funding via a recorded loan), the surcharge test is applied to the child's property holdings — not the parents'. If the child owns no other residential property, no surcharge applies. The SDLT bill drops from £28,000 to £9,000 on a £380,000 Kenton flat. This is not aggressive tax planning; it is an application of the statutory wording, and HMRC's published manual confirms the mechanism.

The qualifying conditions are specific and must be in place before exchange. First: the child must be an adult. Parents' holdings always count for SDLT where a minor child is the beneficiary, regardless of trust structure (Schedule 4ZA FA 2003, paragraph 12). Second: the trust must be a bare trust, not an interest-in-possession trust or a discretionary trust. Bare trusts give the beneficiary absolute entitlement; other trust structures are treated as the trustees' purchase for SDLT and the parents' other properties are included in the surcharge test. Third: the funding structure matters. If the parents gift the purchase money to the child, no further SDLT question arises. If they lend it, the loan should be properly documented as a secured loan against the property (a charge registered at Land Registry) rather than an unsecured transfer, because HMRC scrutinises undocumented parent-child funding flows as potential beneficial-ownership indicators. Fourth: the child must actually be the one who benefits from the property — the right to occupy it, to receive any rental income from it if let, and to dispose of it — not merely nominally.

The trap that catches most Kenton families is retrospective structuring. Parents complete the purchase in their own names, pay the surcharge, and then attempt to execute a declaration of trust or transfer of beneficial interest to the child afterwards. This does not reclaim the surcharge. SDLT is charged on the transaction as it was at completion — the transfer of beneficial interest after the fact is a separate event that does not change the original SDLT treatment. The structure must be in place before exchange. A specialist involved early in the purchase process — ideally before offer acceptance — structures the trust, confirms the funding route, and files the SDLT return on the correct basis. A specialist involved after completion can usually do nothing about the surcharge already paid.
