Guide on Mixed Transactions for Land and Buildings Transaction Tax (LBTT)

LBTT mixed transactions and when a purchase is treated as non-residential

In Scotland, a property purchase that includes both residential and non-residential elements is usually treated as non-residential for the main LBTT calculation. Whether a transaction is truly mixed depends on the facts at the effective date, especially whether there is a genuine and evidenced non-residential use. Land that is really part of the garden or grounds of a home remains residential, and ADS may still apply to the residential part of a mixed purchase.

• A mixed transaction is generally taxed using non-residential LBTT rates and bands, even if it includes a dwelling.
• The key test is the actual character and use of the property at the effective date, not planned future use.
• Evidence of non-residential use can include leases, licences, business accounts, VAT or rates records, grants, and other formal indicators of genuine commercial activity.
• Large grounds, paddocks, stables, woodland or outbuildings do not automatically make a purchase mixed use if they are really part of the home’s garden or grounds.
• Private, hobby or leisure use usually points to residential treatment, while active and substantive commercial use may support mixed status.
• If a mixed transaction includes an additional dwelling, ADS may still be due on the residential part, which must be apportioned on a just and reasonable basis.

LBTT mixed transactions: when a purchase is treated as non-residential

This page explains how Land and Buildings Transaction Tax (LBTT) works when a single transaction includes both residential and non-residential property in Scotland. This matters because a mixed transaction is generally taxed at non-residential rates and bands, but the Additional Dwelling Supplement (ADS) may still apply to the residential part.

What this rule is about

LBTT divides property transactions into residential and non-residential transactions. Some purchases are clearly one or the other. Others are mixed. A common example is a shop with a flat above it. Another is a house bought together with land or buildings said to be used for business.

The key issue is whether the transaction includes any genuine non-residential element at the effective date of the transaction. If it does, the transaction is generally treated as non-residential for the main LBTT calculation.

That does not mean every property with some business connection is mixed use. The classification depends on the facts. In particular, land that is really part of the garden or grounds of a dwelling remains residential, even if it is large or has outbuildings on it.

What the official source says

Revenue Scotland’s guidance says that a transaction containing both residential and non-residential interests is treated as a non-residential transaction. LBTT is then calculated using non-residential rates and bands.

The guidance also says the position must be judged on the facts of the particular transaction. Relevant indicators of non-residential or commercial use can include:

• use of the property at the effective date
• commercial agreements already in place
• formal registrations, licences or local authority records
• VAT registration
• non-domestic rates status
• business accounts
• receipt of agricultural grants or crofting payments
• registered use in the Land Register
• whether activities are carried on as a genuine business with a reasonable prospect of profit
• how the land is viewed by other public bodies

The guidance stresses that use at the effective date overrides past use and intended future use. But historic use can still help show the true relationship of the land to the dwelling at that date, especially where land is temporarily unused or fallow.

It also gives special guidance on a number of recurring issues:

• Bed and breakfasts and guest houses can be residential, mixed or non-residential depending on the facts.
• Furnished holiday lettings are treated as residential property where the building could in most cases be used as a single dwelling without local authority permission, even if assessed to non-domestic rates.
• Land forming part of the garden or grounds of a dwelling is residential. There is no fixed size limit.
• Commercial use can take land outside garden or grounds, but the use must be active, substantive and evidenced.
• Leisure use, including grazing or equestrian use that does not amount to commercial operations, points towards residential treatment.
• A home office within an ordinary dwelling does not usually create mixed use. A separately adapted business area within the building may do so.

The guidance also notes that certain buildings in use for specified purposes are treated as non-residential, such as hotels, inns, hospitals, hospices, prisons, halls of residence and certain care institutions.

Where a mixed transaction includes a dwelling and the buyer is acquiring an additional dwelling, ADS may apply to the residential part only. The residential consideration must then be apportioned on a just and reasonable basis.

What this means in practice

The practical effect is often significant. If a transaction is genuinely mixed, the whole price is taxed at non-residential LBTT rates and bands rather than residential ones. Depending on the figures, that may reduce the main LBTT charge.

But mixed treatment is not available just because a property has some business flavour. The non-residential element must exist in substance at the effective date and must be capable of being evidenced.

In practice, the most disputed area is often land bought with a house. Buyers may assume that paddocks, grazing land, woodland, orchards, stables or outbuildings automatically make a purchase mixed use. The guidance does not support that. If the land is really part of the garden or grounds of the dwelling, the transaction remains residential.

Revenue Scotland says commercial use is important where there is uncertainty over garden or grounds. It expects active and substantive commercial exploitation on a regular basis. Genuine farmland worked commercially is the clearest example. By contrast, land used for private enjoyment, hobby horses, informal grazing or occasional third-party use is much less likely to count as non-residential.

The timing point is also important. A buyer cannot usually turn a residential purchase into a mixed one by saying they plan to run a business from the land after completion. Future intentions do not matter unless the relevant use is already in place at the effective date.

How to analyse it

A sensible way to approach a possible mixed transaction is to ask the following questions.

• What exactly is being acquired in the transaction? Identify each building, structure and parcel of land.
• Is there a dwelling, or land that forms part of the garden or grounds of a dwelling?
• Is any part of the property in genuine non-residential use at the effective date?
• If commercial use is claimed, what evidence exists? For example, leases, licences, accounts, registrations, rates treatment, grants or business records.
• Is the claimed business use regular, active and substantive, or is it really private or leisure use?
• If land is said not to be garden or grounds, what is the true relationship between that land and the dwelling?
• Does the layout support residential enjoyment of the house, or does it point to separate commercial exploitation?
• Is any third-party occupation genuine and exclusive, or only occasional and informal?
• Are you relying on historic use? If so, does it show the real character of the land at the effective date?
• If the transaction is mixed and includes a dwelling, is ADS potentially due on the residential part, requiring a just and reasonable apportionment?

For certain buildings, ask a further question: is the building actually in use as a hotel, inn, hospital, hospice, student hall, prison or qualifying care institution? If yes, the guidance says it is treated as non-residential without considering whether it could also be used as a dwelling.

For home working cases, distinguish between ordinary domestic use of a room as an office and a true physical division or adaptation of part of the building into business premises. The first will usually remain residential. The second may point towards mixed use.

Example

Illustration: a buyer purchases a country house together with surrounding land, stables and a tea room. If, at the effective date, the stables and tea room are ongoing commercial businesses with evidence to support that, the transaction is likely to be mixed. Revenue Scotland’s guidance says the whole transaction is then taxed at non-residential LBTT rates and bands.

By contrast, if the same house includes paddocks and stables used only for the owner’s private horses, and the land is part of the setting and enjoyment of the house, that points towards residential treatment. The presence of stables or paddocks alone does not make the purchase mixed use.

Another illustration is a pub with a flat above. That is a straightforward mixed transaction because it includes non-residential property and a dwelling. The main LBTT charge is calculated at non-residential rates, but ADS may still apply to the residential part if the flat is an additional dwelling and the other ADS conditions are met. The residential part of the price must be apportioned on a just and reasonable basis.

Why this can be difficult in practice

The main difficulty is that the test is highly fact-sensitive. The legislation treats garden or grounds as residential, but there is no fixed size limit. That means disputes often turn on the character of the land rather than its acreage.

Another difficulty is that some indicators point in different directions. For example, non-domestic rates, VAT registration or a grazing agreement may support commercial use, but they are not necessarily decisive on their own. Revenue Scotland says all transactions are treated on their own merits.

Bed and breakfasts, guest houses and holiday accommodation can also be difficult. The guidance does not lay down a single rule for all cases. A bed and breakfast or guest house may be residential, mixed or non-residential depending on the facts. Furnished holiday lettings are treated differently in the guidance and are generally regarded as residential where the building could be used as a single dwelling without planning permission.

Historic use can create further uncertainty. The guidance says the effective date is the key date, but habitual use can still be relevant to reveal the true relationship of the land to the building. That leaves room for judgement where land is temporarily unused.

Finally, mixed transactions can create a second layer of complexity where ADS is potentially in point. A buyer may correctly conclude that the transaction is mixed and therefore taxed at non-residential rates, but still need to consider whether ADS applies to the residential element and how to apportion consideration just and reasonably.

Key takeaways

• A transaction that includes both residential and non-residential property is generally taxed at non-residential LBTT rates and bands.
• The crucial question is the true character and use of the property at the effective date, supported by evidence.
• Land bought with a house is not automatically non-residential just because it is extensive or has paddocks, stables or outbuildings; it may still be garden or grounds and therefore residential.
