Additional Dwelling Supplement Applies to Non-Individual Property Purchases in Scotland

LBTT Additional Dwelling Supplement for Companies, Trusts and Property Businesses

The Additional Dwelling Supplement (ADS) can apply to Scottish residential purchases by companies, other non-individual buyers, certain property business buyers and some trustees, even if it is their first dwelling purchase. This is because these buyers are generally not treated as replacing an only or main residence, so the usual exemption for replacing a main home does not apply.

• ADS generally applies where a Scottish dwelling is bought for £40,000 or more by a company or other non-individual buyer.
• It can also apply to individuals buying in the course of a property investment or property dealing business as a sole trader or partner.
• Trustee purchases may fall within ADS if there is no beneficiary with a right to occupy the dwelling for life or to receive income from it.
• If an individual buys jointly with a company, ADS can apply to the whole transaction and the individual may be jointly liable for the tax.
• When checking whether ADS applies, focus on the buyer’s legal capacity and status, not just whether they already own a home.
• Full relief from ADS may be available if six or more residential properties are bought in a single transaction.

LBTT Additional Dwelling Supplement for companies, trusts and property businesses

This page explains when the Additional Dwelling Supplement, or ADS, applies to purchases of Scottish dwellings by buyers who are not individuals, and to certain purchases by individuals connected with property businesses or trusts. The key point is that these buyers are generally not treated as replacing an only or main residence, so ADS can apply even on a first residential purchase.

What this rule is about

Under LBTT, ADS is an extra charge that can apply when a dwelling in Scotland is bought. For individual homebuyers, much of the analysis usually focuses on whether the buyer already owns another dwelling and whether they are replacing their only or main residence.

This source deals with a different category of buyer. It explains that non-individuals, such as companies and other corporate entities, are not regarded as replacing an only or main residence. That matters because the usual “replacement of main residence” route out of ADS is not available to them.

The source also extends this treatment to some purchases by individuals. In particular, it covers purchases made in the course of certain property investment or property dealing businesses, and some trust purchases where there is no beneficiary with a qualifying interest in the dwelling.

What the official source says

The official material says that ADS applies to chargeable transactions by non-individuals where:

• the transaction consists of or includes the purchase or ownership of a dwelling in Scotland,
• the chargeable consideration is £40,000 or more, and
• the buyer is not an individual, or the buyer is an individual falling within one of the specified categories.

The specified individual categories are:

• an individual buying in the course of a business carried on as a sole trader or as a partner in a partnership, where the sole or main activity of that business is investing or dealing in chargeable interests, or
• an individual acting as trustee under a settlement where there is no interested beneficiary for the dwelling.

The source explains that, for these purposes, chargeable interests include interests that would be chargeable interests but for the fact that the land is outside Scotland.

It also explains what an “interested beneficiary” means in this context. A beneficiary is interested in relation to a dwelling if they have, or will have, a relevant interest in it. A relevant interest means an entitlement to occupy the dwelling for life or an entitlement to income from the dwelling.

The source further states that full relief from ADS is available where a buyer purchases six or more residential properties in one transaction.

What this means in practice

If a company buys a dwelling in Scotland for £40,000 or more, ADS will generally apply even if the company owns no other dwellings at all. The company is not treated like an individual replacing a main home. The fact that it is the company’s first residential purchase does not prevent ADS from applying.

The same broad outcome applies to other non-natural persons, such as investment trusts and other corporate entities, subject to the terms of the legislation and any specific exceptions not covered in this source.

The rule can also catch individuals where the purchase is really part of a property investment or property dealing business. So an individual cannot assume that ADS rules for ordinary homebuyers apply just because the buyer is a natural person. If they are buying as a sole trader, or as a partner, in a business whose sole or main activity is investing or dealing in property interests, ADS may apply on this special basis.

The trust point is also important. A purchase by an individual trustee under a settlement may fall within ADS where there is no interested beneficiary for the dwelling. In other words, if no beneficiary has, or will have, a right to occupy the dwelling for life or a right to income from it, the trustee purchase can be treated in the way described by this rule.

The source also gives a practical warning about joint purchases. If an individual buys jointly with a company, ADS applies to the transaction. The individual cannot avoid ADS by pointing out that they personally own no other property. The company’s status brings the transaction within ADS, and the individual is jointly responsible for the tax due on that purchase.

How to analyse it

A sensible way to approach this issue is to ask the following questions.

• Is the subject matter a dwelling in Scotland, or does the transaction include one?
• Is the chargeable consideration at least £40,000?
• Who is the buyer in legal terms: an individual, a company, trustees, or joint buyers?
• If the buyer is not an individual, is it a non-natural person such as a company or other corporate entity?
• If the buyer is an individual, are they buying in the course of a business whose sole or main activity is investing or dealing in chargeable interests?
• If the buyer is an individual trustee, is there an interested beneficiary for the dwelling?
• Is the transaction a purchase of six or more residential properties in one transaction, so that the full relief mentioned in the source may apply?

Two points are especially important.

First, do not start with the ordinary homeowner question of whether the buyer is replacing their main residence unless the buyer is actually in the category of individuals to whom that concept can apply. For companies and similar entities, the source says they are not regarded as replacing an only or main residence.

Second, identify the true capacity in which an individual is buying. An individual may be buying personally, as a sole trader, as a partner, or as trustee. The result can differ depending on that capacity.

Example

Illustration: A newly formed company buys a single flat in Scotland for more than £40,000 as its first buy-to-let property. It owns no other dwellings. ADS still applies. The reason is not that the company already owns another property. It is that a non-individual buyer of a dwelling is not treated as replacing an only or main residence, so the company falls within the ADS rule for non-individuals.

Illustration: The same company buys the flat jointly with an individual who has never owned property before. ADS still applies to the transaction. The individual does not escape ADS simply because they personally are a first-time buyer. They are buying jointly with a company, and the source says they are jointly responsible for the ADS due.

Why this can be difficult in practice

The main difficulty is classification. A buyer may be an individual in form, but the purchase may still fall within these rules if it is made in the course of a property investment or property dealing business. Deciding whether the sole or main activity of a business is investing or dealing in chargeable interests can be fact-sensitive.

Trust cases can also be awkward. Whether there is an interested beneficiary depends on the terms of the settlement and the nature of the beneficiary’s rights. The source gives a specific meaning: a right to occupy for life or a right to income from the dwelling. In practice, the trust deed and the beneficiary’s actual entitlements need to be examined carefully.

Joint purchases can create misunderstanding. A common mistake is to focus only on the individual co-buyer’s position and ignore the status of the company or other non-individual buyer. The source makes clear that the presence of the non-individual buyer can bring the whole transaction within ADS.

Finally, the source mentions full relief where six or more residential properties are bought in one transaction. That is a significant point, but it sits within the wider LBTT framework and may require checking the detailed conditions for that relief elsewhere.

Key takeaways

• A company or other non-individual buying a Scottish dwelling for £40,000 or more will generally face ADS even on its first residential purchase.
• Some individuals are treated similarly, especially where they buy in a property investment or dealing business or as trustees without an interested beneficiary.
• A joint purchase with a company can trigger ADS for the whole transaction, and buying six or more residential properties in one transaction may qualify for full relief.
