Does an overseas cabin count as another dwelling for the SDLT higher rates?

Introduction

A common SDLT question is whether owning a property abroad can trigger the higher rates when buying a home in England. The answer depends on whether the overseas asset is treated as a “dwelling” for SDLT purposes and, in some cases, whether it is worth at least £40,000. This becomes more complicated where the overseas property is a leisure cabin, lodge, hostel-style building, or something that may not fit neatly into an ordinary residential category.

Readers often search for this issue because they are buying a main home in England but already own some form of holiday or leisure accommodation overseas. They want to know whether that existing interest counts as an additional dwelling and therefore increases the SDLT bill.

The Question

A buyer plans to purchase a residential property in England to live in as their home. They also own an overseas cabin or lodge used for short-stay or leisure purposes. The building may be movable, or it may be fixed in place. It has also been used in a way that looks partly commercial, with shared facilities, meeting space, and dormitory-style sleeping arrangements.

The buyer wants to know whether that overseas property counts as a dwelling for SDLT purposes and whether it would trigger the higher rates for additional dwellings on the English purchase.

Nick’s Explanation

Nick’s core point was that the SDLT answer turns first on what the overseas structure actually is.

He explained, in substance, that if the cabin is like a caravan and is not permanently fixed in one place, it will generally not be treated as a dwelling for these purposes. If so, it would not need to be counted when the SDLT return is completed for the English purchase.

He also noted that if the structure is a fixed building, value matters as well. If the buyer’s interest in that property is worth less than £40,000, it is generally not counted as an additional property for the higher rates.

Nick then identified a further point: even where the building is fixed, the legal question is not simply whether people can sleep there. The legislation distinguishes between buildings used as dwellings and certain buildings that are specifically treated as not being dwellings, such as “a hotel or inn or similar establishment”.

That means the classification of the overseas property depends on its nature and use at the effective date of the English transaction. A lodge or hostel-style building used for short-term accommodation may not necessarily be a dwelling. But that conclusion depends on the facts, not just the label attached to the building.

The Law

The starting point is the SDLT higher rates regime in Schedule 4ZA to the Finance Act 2003. Broadly, the higher rates can apply if, at the end of the day of the transaction, the buyer owns a major interest in another dwelling worth £40,000 or more, and the purchase is not replacing the buyer’s only or main residence.

Overseas property can count. The rules are not limited to dwellings in the UK. So if a buyer owns a qualifying dwelling anywhere in the world, that can be relevant.

The meaning of “dwelling” is addressed in section 116 Finance Act 2003. Section 116(2) and section 116(3) are particularly important. Section 116(3) provides that certain buildings are not used as dwellings, including:

• a home or other institution providing residential accommodation for children;
• a hall of residence for students in further or higher education;
• a home or other institution providing residential accommodation with personal care for persons in need of personal care;
• a hospital or hospice;
• a prison or similar establishment; and
• a hotel or inn or similar establishment.

Section 116(2) identifies certain uses that are treated as use as a dwelling, including some forms of institutional residential accommodation.

HMRC’s SDLT manual at SDLTM10023 also addresses buildings that are not dwellings, including caravans and houseboats in the appropriate context. A structure that is not permanently fixed may fall outside the concept of a building used as a dwelling.

For the higher rates, HMRC also states that a property worth less than £40,000 is generally ignored when deciding whether the buyer owns another dwelling.

Where a taxpayer argues that a property is unsuitable for use as a dwelling, the current threshold is relatively high following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799. Ordinary disrepair or the need for works will often not be enough. The building must fail the test in a more fundamental way.

Analysis

The analysis usually has four stages.

First, identify whether the overseas asset is a building at all for SDLT purposes. If it is more like a caravan or other movable structure and is not permanently fixed in one location, that strongly points away from it being a dwelling. In that case, it is unlikely to count for the higher rates.

Second, if it is a fixed building, ask whether the buyer’s interest is worth at least £40,000. If the value is below that threshold, it is generally ignored for the higher rates even if it might otherwise be residential.

Third, if it is a fixed building worth £40,000 or more, consider whether it is actually a “dwelling” within section 116. This is where the nature of occupation and use becomes critical. A building used as a hotel, inn or similar establishment is specifically treated as not being a dwelling under section 116(3)(f). So a lodge or hostel-style property used for short-stay guest accommodation may fall outside the dwelling definition if the facts support that treatment.

Fourth, focus on the position at the effective date of the transaction. In SDLT, classification is generally determined by the facts at the transaction date, not by what the buyer intends to do with the property later. So if the overseas building is currently being run in a way that is genuinely similar to a hotel, inn, hostel or other short-stay commercial accommodation, that current use may be highly relevant.

However, labels alone do not decide the issue. Calling a property a “lodge”, “hostel” or “corporate rental” does not automatically make it non-residential. HMRC and the tribunals will look at the real characteristics of the property and how it is used. Questions that matter include:

• Is it occupied by transient guests or by residents?
• Is it run like short-stay accommodation or like a home?
• Are there shared facilities and service elements typical of hospitality use?
• Is there any planning or licensing material describing the use?
• Is the building structurally suitable for ordinary residential occupation?

If someone instead argues that the building should be ignored because it is uninhabitable or not suitable for use as a dwelling, that is now a difficult route. Following Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799, the threshold is relatively high. The property must be unsuitable in a real and substantial sense. Mere poor condition, dated layout, or a need for refurbishment is unlikely to be enough.

Outcome

The practical answer is as follows:

• If the overseas cabin is not permanently fixed and is more like a caravan or similar movable structure, it is unlikely to count as another dwelling.
• If it is a fixed building but worth less than £40,000, it is generally ignored for the SDLT higher rates.
• If it is a fixed building worth £40,000 or more, the key issue is whether it is a dwelling at the transaction date or whether it falls within an exclusion such as “a hotel or inn or similar establishment” under section 116(3)(f) Finance Act 2003.
• Future plans for personal use or broader letting are usually less important than the actual facts at the effective date of the purchase.

Practical Steps

To assess the position properly, a buyer should gather evidence on the overseas property before exchange and completion:

• Confirm whether the structure is permanently fixed to land.
• Obtain a realistic market valuation to test the £40,000 threshold.
• Collect documents showing current use, such as booking records, marketing material, licences, planning documents, and photographs.
• Check whether the accommodation is run like short-stay guest accommodation rather than ordinary residential living.
• Record the factual position as at the effective date of the English purchase.
• If relying on the property being unsuitable for use as a dwelling, make sure the evidence meets the now relatively high threshold after Amarjeet and Tajinder Mudan v The Commissioners for HMRC [2025] EWCA Civ 799.

Because the SDLT return is filed on the basis of the facts at completion, the buyer should make sure their conveyancer has the relevant details in time to complete the SDLT1 correctly.

Conclusion

An overseas cabin does not automatically trigger the SDLT higher rates. The key questions are whether it is a fixed building, whether it is worth at least £40,000, and whether it is legally a “dwelling” at the transaction date. A movable leisure unit may not count at all, and a fixed property used in a way similar to a hotel or inn may also fall outside the dwelling definition. The answer is fact-sensitive, but the legislation gives a clear framework for analysing it.
