Understanding the specifications and implications of Stamp Duty Land Tax (SDLT), especially the concept related to mixed-use properties, is essential when buying property in England. When a property has both residential and non-residential components, such property are considered as a mixed-use property and is assessed at non-residential SDLT rates, which are lower than residential SDLT rates, resulting in SDLT savings for the buyer.
This case before the First-tier Tribunal (FTT) examines the distinction between residential "grounds" and commercially used land, specifically addressing whether agricultural grazing arrangements can establish mixed-use status for SDLT purposes.
Background
Mr. Martin and Mrs. Julia Lynch (the “Appellant”) purchased a property on 7 May 2021, The Property consisted of a large, five-bedroom house, a one-bedroom converted barn, a two-bedroom cottage, various domestic outbuildings and 22 acres of land (together the “Property”). The 22 acres of land included extensive formal gardens, a kitchen garden, and 18 acres of paddocks (“Grazing land”). The purchase price of the Property is £3,075,000, and Appellants paid SDLT of £258,750 on the basis that the Property was wholly residential and applied for Multiple Dwellings Relief (MDR).
Facts
At the time of purchase, the Property included grazing land that was being utilised by Mr. Watts (“a farmer”) for the purpose of grazing his beef cattle. No formal grazing agreement existed between the parties; instead, the arrangement operated under informal arrangement in the continuation of the operational practices that had been established under the previous ownership.
On 5 May 2022, the Appellant filed a claim to HMRC for overpayment relief amount of £104,433. The application was submitted under the provisions of Schedule 10, Paragraph 34 of the Finance Act 2003, which grants taxpayers the statutory right to claim relief where SDLT has been overpaid on a property transaction. Following, HMRC issued a closure notice that reduced the Appellant's claim to nil, thereby denying the relief, which resulted in the Property being classified as residential. On 19 May 2023, the Appellant appealed to the FTT challenging HMRC's decision to deny the SDLT overpayment relief claim.
Legal Issue
Whether the 18 acres of grazing land formed part of the “grounds” of the dwelling under section 116(1)(b) of the Finance Act 2003, thus rendering the entire property residential for SDLT purposes or whether it had a sufficiently separate commercial function to make the property "mixed use."?

Appellant's and Respondent's Arguments
The Appellants contended that the grazing arrangements were sufficiently commercial in nature to take the 18 acres outside the definition of "grounds" under Section 116 (1) (b) of the Finance Act 2003. They argued that The Grazing Land was, at the Effective Date of the transaction, being used by a third party for his own business use, namely, grazing cattle to fatten and sell them. The Grazing Land could not be seen from the house and did not form part of the “treasured view” which was a selling point of the Property as per its advertising brochure. The Grazing Land did not contribute to the security and privacy of the dwelling. On the contrary, the use of the land by a third party and the use of the footpaths by the public made it the least secure part of the Property. The Appellants did not need such a large piece of land and had no use for the Grazing Land. Indeed, they found it something of a liability when they had to maintain it themselves. The grazing arrangements were an intrusion on the Property.
On the contrary, HMRC argued that the grazing arrangements were not genuinely commercial but rather constituted a mere informal understanding that suited both parties without creating a true commercial relationship. They emphasized that the rent was nominal in nature and that the arrangement was primarily beneficial to both parties for practical land management reasons rather than commercial profit. HMRC contended that the informal nature of the arrangements, the lack of any formal agreement at completion, and the Appellants' failure to receive any consideration during their ownership period demonstrated that this was not a commercial use sufficient to take the land outside the "grounds" definition. They argued that the land retained its character as grounds because the Appellants maintained full control and access rights, the farmer had no exclusive possession, and the arrangements could be terminated at will. HMRC further argued that the substantial size and rural character of the property meant that 18 acres was proportionate and appropriate for grounds of such a dwelling, and that the land continued to contribute to the overall residential setting and character of the property.
Holding
The FTT dismissed the appeal, holding that the 18 acres of grazing land constituted "grounds" of the dwelling, making the entire Property wholly residential and confirming that the correct amount of SDLT was paid, hence no relief to be claimed.
Reasoning
The FTT applied a multi-factorial test, which states that no one factor is determinative, and different factors may be given different weight. The FTT must carry out a balancing exercise, weighing up all the factors to come to a balanced judgement as to whether the land in question constitutes “grounds” of a dwelling established in the Hyman case, giving weight to the actual use of the land and whether it is separate from the dwelling.

While the land was used by a third party for his commercial cattle business, several factors supported the "grounds" classification such as: the land was purchased in a single transaction with common ownership, was adjacent to the formal gardens, was of appropriate size for a substantial country property, and the farmer did not have exclusive possession.
The FTT found that the grazing arrangements were informal and non-commercial from the Appellants' perspective, as they received no consideration and could terminate the arrangement at their will. Critically, the FTT determined that the grazing use did not prevent the land from functioning as an "appendage" to the dwelling and was not separate from the residential use of the main house. The Appellants retained full rights over the land and could use it whenever they wished.
Conclusion
This case became a cautionary lesson for anyone buying rural properties with agricultural elements in it. This demonstrated that, in the world of tax law, intentions, traditional arrangements, and even agricultural use are insufficient to prevent agricultural land from being classified as "grounds" of a residential property for SDLT purposes. If you want a mixed-use SDLT treatment, you will have to have: Any form of formal written agreement between two parties such as Farming Business Tenancy, etc. Have exclusive commercial rights, Legal separation between residential and commercial elements and Documentation that would satisfy a tax tribunal.
