The First-tier Tribunal’s (FTT’s) decision in Sinclair & Anor v HMRC [2026] UKFTT 798 (TC) addresses whether a farmhouse acquired with a field used for grazing sheep under an informal arrangement at the time of purchase amounted to a mixed-use property for Stamp Duty Land Tax (SDLT), which would have enabled the lower non-residential or ‘mixed-use’ rates to apply.
Background
The taxpayers purchased a property comprising a Grade II listed farmhouse, gardens, and an adjoining one-acre field (the Field), which had been historically used as part of a larger farm, for £1.81 million. The Field was subject to an informal, unsigned grazing agreement with a neighbouring farmer, who had grazed sheep intermittently for a period of six years before the property was acquired by the taxpayers. The Field was also classified as agricultural land for planning and council tax purposes. The taxpayers were reluctant to purchase the Field due to the associated maintenance costs, and the Field did not add to the views of the farmhouse (in comparison to the gardens) as it was only visible from the utility room.
In this regard, the taxpayers had self-assessed that SDLT of £80,000 was payable, on the basis that the property was ‘mixed-use’. In particular, the taxpayers sought to argue that the Field was not grounds of the farmhouse (which would otherwise make the transaction subject to the higher residential rates) by reference to its agricultural classification, the existence of the grazing arrangement, and the lack of residential use. However, this SDLT self-assessment was challenged by HMRC which led to the appeal to the FTT.
FTT’s Decision
The FTT concluded that the Field had formed part of the grounds of the farmhouse and found that HMRC were correct in asserting that the higher SDLT residential rates applied.
The FTT adopted the multifactorial approach which considers a number of factors such as ownership, contiguity, layout, accessibility, privacy, historic and current use, legal constraints, and whether the land serves a function in relation to the dwelling, whether active or passive. In this regard, the FTT emphasised that the agricultural classification or the mere existence of the grazing agreement, especially one that is informal and not exclusive, were relevant but not determinative in automatically rendering the Field non-residential. In this case, the FTT found that the Field remained part of the grounds because the Field was contiguous with the farmhouse and gardens, it added to rural character and enhanced privacy and security of the farmhouse (despite the lack of views from the house), and despite the grazing arrangement, the grazing on the Field was intermittent, lacked substantial or exclusive commercial exploitation of the Field (i.e. the arrangement was akin to a ‘barter of convenience’), and ultimately, it was easily terminable.
Why this case matters
Sinclair is a reminder that the SDLT treatment of ‘grounds’ cases is highly fact sensitive. In recent years, there has been a marked increase in disputes where taxpayers argue that fields or paddocks bought with a dwelling, often subject to grazing agreements of varying formality, can ‘extricate’ the land from definition of grounds of a dwelling, thereby allowing the entire transaction to qualify for the lower ‘mixed-use’ rates. In some instances, the existence of the grazing arrangements has been enough to tip the case in the taxpayer’s favour but in other cases it has not. What is clear is that there is no determinative factor in these ‘ground’ cases because, as the FTT points out in Sinclair, what may at first sight be a small difference could lead to the multifactorial evaluation tipping one way or another.
Therefore, buyers should be cautious of assuming that the mere presence of a grazing agreement or agricultural classification will suffice to secure ‘mixed use’ rates. It is only one of many factors in the proverbial fence which divides the fields from the garden and grounds of a dwelling.
