Does ADS apply if you buy two Scottish properties in one transaction and each is worth less than £40,000?

Introduction

A common point of confusion with the Scottish Additional Dwelling Supplement (ADS) is the £40,000 threshold. Buyers often ask whether that threshold is tested by looking at each dwelling separately or by looking at the total price paid for the whole transaction.

This matters in cases where one buyer purchases more than one residential property at the same time, especially where each individual property is below £40,000 but the combined price is above that figure. The answer turns on how the Land and Buildings Transaction Tax (Scotland) Act 2013 applies to a single chargeable transaction.

The Question

An individual buyer already owns another residential property and is purchasing two residential properties in Scotland from one seller in a single transaction. Each property is worth £35,000, so each is below £40,000, but the total price for the transaction is £70,000. The buyer is not replacing their only or main residence.

The question is whether ADS applies when each dwelling is individually below the £40,000 threshold.

Nick’s Explanation

Nick’s view was that ADS does apply in this situation because the legislation looks at the total relevant consideration for the chargeable transaction, not the separate value of each dwelling.

In anonymised form, his explanation was:

“ADS applies to a chargeable transaction only if the total relevant consideration is £40,000 or more. If two dwellings are bought in one transaction for a combined £70,000, that threshold is met. If the buyer already owns another dwelling and is not replacing their only or main residence, ADS is chargeable on the full consideration.”

He also addressed the wording of the legislation, which refers to “a dwelling”. His point was that this does not prevent the rules applying where more than one dwelling is acquired in the same transaction. That singular wording is ordinary legislative drafting and does not confine the charge to purchases involving only one dwelling.

He further corrected the rate point raised in the exchange: the ADS rate is 8% from 1 January 2025.

The Law

The relevant legislation is the Land and Buildings Transaction Tax (Scotland) Act 2013, especially Schedule 2A.

In broad terms, ADS applies to certain purchases of additional residential property. One of the gateway conditions is found in Schedule 2A, paragraph 2(1)(b): the chargeable transaction must involve relevant consideration of £40,000 or more.

For ADS purposes, the legislation focuses on the chargeable transaction. Where multiple dwellings are acquired as part of one transaction, the question is not whether each dwelling separately costs at least £40,000. The question is whether the transaction itself has relevant consideration of at least £40,000.

Other conditions also need to be satisfied, including that:

• the buyer is acquiring a major interest in a dwelling,
• the buyer already owns another dwelling, and
• the purchase is not a replacement of the buyer’s only or main residence.

If those conditions are met, ADS is generally charged on the full consideration attributable to the transaction.

Analysis

Applying the rules step by step:

1. There is one chargeable transaction. The buyer is acquiring two residential properties together in a single purchase.

2. The total consideration for that transaction is £70,000.

3. That total exceeds the £40,000 threshold in Schedule 2A, paragraph 2(1)(b).

4. The buyer already owns another dwelling.

5. The purchase is not a replacement of the buyer’s only or main residence.

6. As a result, the normal ADS conditions are met.

The fact that each dwelling is worth only £35,000 does not prevent ADS from applying. The threshold is tested by reference to the total consideration for the transaction, not by splitting the transaction into separate dwelling values.

The wording “a dwelling” does not change that outcome. In UK legislation, singular terms commonly include the plural unless the context requires otherwise. Here, the statutory scheme and Revenue Scotland’s approach both support looking at the transaction as a whole where multiple dwellings are bought together.

On the figures given, ADS would therefore be charged on £70,000 at the applicable ADS rate. As noted above, that rate is 8% from 1 January 2025.

Outcome

Yes. ADS applies in this scenario.

Even though each property is individually worth less than £40,000, the buyer is acquiring two dwellings in one chargeable transaction for total consideration of £70,000. Because the buyer already owns another dwelling and is not replacing their only or main residence, ADS is payable on the full transaction consideration.

Practical Steps

If you are assessing a similar purchase, work through the following points:

• Identify whether you are buying one or more dwellings in a single chargeable transaction.
• Calculate the total consideration for that transaction.
• Check whether the total reaches or exceeds £40,000.
• Confirm whether you already own another dwelling anywhere in the world, subject to the detailed statutory rules.
• Decide whether the purchase is replacing your only or main residence. If it is not, ADS may apply.
• Check the current ADS rate in force on the effective date of the transaction.
• Where the structure is unusual, such as linked transactions, mixed property, multiple titles or possible reliefs, review the legislation and Revenue Scotland guidance carefully before filing the LBTT return.

Conclusion

For Scottish ADS, the £40,000 test is applied to the transaction, not to each dwelling looked at in isolation. If two dwellings are bought together for a combined £70,000, the threshold is met. Where the buyer already owns another dwelling and is not replacing their main home, ADS will usually be due.
