Guidance on Mixed Transactions: Residential and Non-Residential Land and Buildings Tax (LBTT

LBTT mixed transactions and non-residential treatment in Scotland

When a Scottish property purchase includes both residential and non-residential elements, it is usually treated as a non-residential transaction for the main LBTT calculation. The key test is the property’s actual use at the effective date, supported by evidence. Even so, the Additional Dwelling Supplement may still apply to the residential part if its conditions are met.

• A mixed transaction, such as a shop with a flat above, is generally charged to LBTT using non-residential rates and bands on the full price.
• The main question is whether there is a genuine non-residential element at the effective date; past use and future plans are less important.
• Land that forms part of a dwelling’s garden or grounds remains residential, and there is no fixed size limit, so houses with land often need careful factual analysis.
• Revenue Scotland expects objective evidence of commercial use, such as business accounts, non-domestic rates, VAT registration, grazing agreements, or agricultural registrations.
• Working from home in an ordinary room will not usually create mixed use, but a separate or specially adapted business area might.
• If the purchase includes a dwelling and ADS conditions are met, ADS may be charged on the residential element only, using a just and reasonable apportionment of the price.

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

This page explains how Land and Buildings Transaction Tax (LBTT) works when a 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 draws a basic distinction between residential and non-residential property. Some purchases are clearly one or the other. Others are mixed. A common example is a shop with a flat above it.

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

This is especially important where the property includes land around a house, business use within a building, holiday accommodation, farmland, grazing land, or other areas that may or may not count as part of a dwelling’s garden or grounds.

What the official source says

Revenue Scotland’s guidance says that a transaction containing a mixture of residential and non-residential interests is treated as a non-residential transaction. The whole consideration is therefore charged using non-residential LBTT rates and bands.

The guidance also says:

• Commercial use must be supported by evidence if it is relied on to treat land or buildings as non-residential.
• The use of the property at the effective date overrides past use or future intentions, although habitual use may still help show the true character of the land at that time.
• Land forming part of the garden or grounds of a dwelling is residential under section 59(1)(b), and there is no fixed size limit.
• If there is doubt about whether land is garden or grounds, Revenue Scotland looks closely at whether it is being actively and substantively exploited on a commercial basis.
• Some buildings in actual use for particular institutional or trading purposes, such as hotels, inns, hospitals, prisons and certain care institutions, are treated as non-residential.
• A home office within an ordinary dwelling will usually not make the property mixed use, but a physically separate or adapted business area may do so.
• In a mixed transaction, ADS can still apply to the residential part if the conditions for ADS are met. The residential consideration must be apportioned on a just and reasonable basis.

What this means in practice

The practical question is not simply whether some business activity happens somewhere on the property. The real question is whether, on the effective date, there is a genuine non-residential element that can be evidenced.

For example:

• A shop with living accommodation above it is a straightforward mixed transaction.
• A country house with land said to be “commercial” is more fact-sensitive. If the land is really part of the home’s grounds, residential treatment may still apply.
• Land used for genuine commercial farming, commercial woodland, a registered croft, or commercial grazing may point towards mixed use or non-residential treatment.
• Land used only for leisure grazing, private equestrian use, orchards, domestic outbuildings or hobby activities is more likely to remain part of the garden or grounds and so remain residential.

The guidance makes clear that labels are not enough. Revenue Scotland expects evidence such as VAT registration, non-domestic rates status, business accounts, commercial registrations, rural payments, agricultural registrations, grazing agreements, or similar material.

It also matters that the use exists at the effective date. A buyer cannot usually turn a residential purchase into a mixed one merely by saying they plan to run a business there later.

How to analyse it

A sensible way to analyse a possible mixed transaction is to work through these questions.

1. What is being bought?

   Identify each building, area of land, and any separate unit of occupation or use.

2. What is the use at the effective date?

   This is the starting point. Past use and intended future use are not decisive, although regular historic use may help show the true relationship of the land to the property at that date.

3. Is any part genuinely non-residential?

   Look for active and substantive commercial exploitation on a regular basis. The guidance points to genuine farming, horticulture, commercial stables, commercial grazing, commercial woodland, crofting, and similar activities.

4. Could the land still be part of the garden or grounds?

   If land forms part of the garden or grounds of a dwelling, it is residential. There is no statutory acreage limit. The question is factual. Layout, connection to the house, domestic use, leisure use, and the overall character of the property all matter.

5. What evidence exists?

   Revenue Scotland expects objective evidence. Informal or occasional use is less persuasive than business accounts, rates treatment, formal agreements, registrations, grants, or established trading records.

6. Is there a lease or licence to a third party?

   An exclusive lease to a third party may indicate non-residential use, but occasional or limited permission for others to use land will not necessarily stop it being garden or grounds. The true nature, start date and duration of the arrangement matter.

7. Is the building merely being used for work from home?

   If a room in a house is used as an office but remains part of the dwelling, that will usually still be residential. A separately adapted business area may be different.

8. If the transaction is mixed, is ADS also in point?

   If the purchase includes a dwelling and the ADS conditions are met, ADS may apply to the residential part only. You then need a just and reasonable apportionment of the consideration.

Example

Illustration: a buyer purchases a pub with a flat above it in a single transaction. The pub is non-residential and the flat is residential. That makes the purchase a mixed transaction, so the main LBTT charge is calculated using non-residential rates and bands.

However, if the flat counts as an additional dwelling for ADS purposes, ADS may still be payable on the part of the price that is just and reasonably attributed to the flat.

This shows the two-stage effect:

• main LBTT on the whole mixed transaction at non-residential rates
• possible ADS on the residential element only

Why this can be difficult in practice

The hardest cases are usually not obvious mixed buildings like a shop and flat. They are houses with land.

The main difficulty is the boundary between:

• land that is part of the dwelling’s garden or grounds, which is residential, and
• land that is genuinely being used for commercial, non-residential purposes.

The guidance does not set a simple mechanical test. There is no fixed size limit for garden or grounds. Proximity to the house matters but is not decisive. Historic use can matter, but only to show the true status at the effective date. Future plans do not count unless already in place.

Another difficulty is that some indicators can point in different directions. For example, paying non-domestic rates or having a VAT registration may support a commercial case, but they are not necessarily conclusive on their own. Equally, occasional grazing or hobby equestrian use may look “rural” without being commercial enough to make the land non-residential.

Holiday accommodation can also be counterintuitive. The guidance says a property used as part of a furnished holiday letting business will be residential, even if assessed to Council Tax or non-domestic rates, because in most cases it could still be used as a single dwelling without local authority permission.

Bed and breakfasts and guest houses are also fact-sensitive. Revenue Scotland says they may be residential, mixed or non-residential depending on the facts, with both Council Tax and non-domestic rates treatment taken into account.

Key takeaways

• If a transaction includes both residential and non-residential property, the main LBTT charge is generally calculated at non-residential rates and bands.
• The status of the property at the effective date is central, but regular historic use may help show its true character at that time.
• For houses with land, the critical issue is often whether the land is really part of the garden or grounds, or is instead being genuinely and provably exploited on a commercial basis.
