Guidance on Additional Dwelling Supplement Exemptions and Reliefs in Scotland
When ADS does not apply or can be reduced for LBTT
Scotland’s Additional Dwelling Supplement (ADS) does not apply if a transaction is exempt from LBTT, and it can also be reduced or removed by some LBTT reliefs. Gifts and inheritances do not trigger ADS when received, but those properties may still count later when deciding if ADS is due on a future purchase. ADS also does not apply to non-residential transactions, including a single purchase of six or more separate dwellings.
- If a transaction is fully exempt from LBTT, ADS does not apply to that transaction.
- A gift or inheritance of a dwelling does not itself trigger ADS, but the property may still count towards the buyer’s total dwellings for later ADS purposes.
- Some ordinary LBTT reliefs, such as certain reliefs for house builders, social landlords and local authorities, can also reduce or remove ADS.
- If LBTT relief is only partial, any ADS due is reduced by the same proportion rather than cancelled completely.
- ADS is not charged on non-residential transactions, and a single transaction involving six or more separate dwellings is treated as non-residential.
- Where Multiple Dwellings Relief applies and ADS is due on only some dwellings, the tax must be worked out for each dwelling separately and ADS added only where it actually applies.

ADS exemptions and reliefs for LBTT: when the supplement does not apply, and when relief is available
This page explains the main situations in which Scotland’s Additional Dwelling Supplement (ADS) does not apply, or can be reduced or relieved. The source material is brief and technical. In practice, these rules matter because a dwelling can be ignored for one purpose but still count for another, and because some reliefs affect ADS differently depending on the transaction structure.
What this rule is about
ADS is an additional amount of Land and Buildings Transaction Tax charged on certain purchases of dwellings. The question on this page is not when ADS applies generally, but when it does not apply, or when a buyer can claim relief from it.
The source material covers five main points:
- some transactions are outside ADS because they are exempt from LBTT in the first place
- gifts and inheritances do not trigger ADS when received, but may still count when working out later ADS liability
- some ordinary LBTT reliefs also reduce or remove ADS
- ADS does not apply to non-residential transactions, including certain purchases of six or more dwellings in one transaction
- there are special calculation points where Multiple Dwellings Relief (MDR) is claimed and ADS is payable on only some of the dwellings
What the official source says
The official guidance says that if a transaction is exempt from LBTT, ADS does not apply to that transaction. A gift of a dwelling is given as an example. It also says that if you inherit a dwelling, ADS does not apply.
However, the same guidance makes an important separate point: gifted and inherited dwellings can still count towards the number of dwellings a person owns. That ownership count can affect whether ADS becomes payable on a later purchase.
The guidance also says that standard LBTT reliefs can apply where an additional dwelling is being bought. Examples mentioned are:
- house builders in partial exchange cases
- certain transactions by social landlords
- certain purchases by local authorities
Where LBTT relief is only partial, any ADS due is reduced by the same proportion.
On non-residential property, the guidance says ADS is not charged on non-residential transactions. It then highlights a specific rule for six or more dwellings: where six or more separate dwellings are transferred in a single transaction, they are treated as non-residential property. The practical result is that ADS does not apply to that transaction.
For MDR, the guidance explains that the normal MDR calculation is adjusted where ADS is payable. In most cases, tax is worked out by reference to average consideration per dwelling, so each dwelling produces the same result. But if ADS applies to some dwellings and not others, each dwelling must be considered individually and ADS added only for the dwellings to which it actually applies. One example given is where one dwelling is a replacement main residence, because ADS does not apply to a replacement of a main residence.
What this means in practice
The main practical point is that there is a difference between:
- whether ADS is charged on the transaction you are currently looking at, and
- whether a dwelling is counted as part of the buyer’s property ownership position for a future transaction
That distinction is easy to miss.
For example, receiving a dwelling by inheritance does not itself trigger ADS. But if you later buy another dwelling, that inherited property may still be counted when deciding whether you already own more than one dwelling at the end of the effective date.
The same is true for gifts in an LBTT-exempt context. No ADS may arise on the gift itself, but the dwelling may still matter later when counting dwellings owned.
The guidance also shows that relief from ADS is not limited to special ADS-only rules. Some LBTT reliefs carry through into the ADS calculation. If LBTT is relieved in full, that may eliminate ADS. If LBTT is relieved only in part, ADS is reduced on the same fraction rather than disappearing altogether.
The six-or-more-dwellings rule is especially important for investors, companies and bulk purchasers. If six or more separate dwellings are bought in one transaction, the transaction is treated as non-residential. That takes the transaction out of ADS. But the guidance also makes clear that this depends on there being a single transaction involving six or more separate dwellings. Splitting an acquisition into smaller transactions may prevent the relief from applying.
How to analyse it
A sensible way to analyse an ADS exemption or relief question is to work through these steps.
Ask first whether the transaction is exempt from LBTT altogether.
If it is, ADS will not apply to that transaction.
If the dwelling was acquired by gift or inheritance, separate the immediate tax result from the future counting result.
The source says ADS does not apply on inheritance, and gives a gift as an example of an LBTT-exempt transaction. But those dwellings may still count towards the number of dwellings owned for later purchases.
Check whether any LBTT relief applies.
If the transaction qualifies for an LBTT relief, consider whether it removes LBTT entirely or only partly. If the relief is partial, the same proportion applies to ADS.
Decide whether the transaction is residential or non-residential for these purposes.
ADS is not charged on non-residential transactions. A single transaction involving six or more separate dwellings is treated as non-residential.
If MDR is claimed, check whether ADS applies to all the dwellings or only some.
If ADS applies to all of them, the average-consideration approach will often produce the same amount for each dwelling. If ADS applies only to some dwellings, you need to calculate the tax due on each dwelling individually and add ADS only where appropriate.
For ownership-count questions, consider all dwellings owned at the end of the effective date, including properties outside Scotland and, where relevant, gifted or inherited dwellings.
The example in the guidance expressly says the inherited dwelling can be anywhere in the world and still count for ADS ownership-count purposes.
Example
Illustration 1: inherited property and a later buy-to-let purchase
A buyer owns and lives in one dwelling as their main residence. They then inherit a share in another dwelling from a parent. No ADS arises on the inheritance itself. Later, they buy a buy-to-let property. At the end of the effective date of that later purchase, the inherited dwelling may still count as an owned dwelling, so it can affect whether ADS is due on the buy-to-let purchase.
The source notes an important timing point here. For effective dates on or after 1 April 2024, an inherited dwelling only counts where the value of the individual inherited share is £40,000 or more.
Illustration 2: buying eight flats in one transaction
A company buys a building that has been divided into eight separate flats, all in one transaction. Even if the company owns no other dwellings, the transaction involves six or more separate dwellings in a single transaction. Under the rule highlighted in the guidance, the transaction is treated as non-residential. LBTT may still be payable, but ADS is relieved in full.
Why this can be difficult in practice
Several parts of this area are easy to misread.
First, people often assume that if no ADS was charged when a dwelling was acquired, the dwelling is irrelevant later. That is not what the guidance says. A dwelling can be outside ADS on acquisition but still count when working out later ADS exposure.
Second, the six-or-more-dwellings rule depends on the structure of the transaction. The guidance stresses a single transaction. If acquisitions are divided into separate transactions, the result may be different.
Third, MDR and ADS do not always fit neatly together. If one dwelling in a multiple purchase is a replacement main residence and the others are not, a simple average approach may be misleading. The guidance says the tax due must then be calculated dwelling by dwelling, with ADS added only for the dwellings to which it applies.
Fourth, the source refers to reliefs available under wider LBTT legislation, but it does not set out the detailed qualifying conditions for each relief. So the existence of a relief category does not mean every transaction involving a house builder, social landlord or local authority will qualify. The detailed statutory conditions still matter.
Finally, the inherited-property example includes a date-based rule about counting only where the individual inherited share is worth at least £40,000 for effective dates on or after 1 April 2024. That shows that even within this area, the counting rules can change over time and must be matched to the transaction date.
Key takeaways
- If a transaction is exempt from LBTT, ADS does not apply to that transaction.
- Gifted and inherited dwellings may still count towards the number of dwellings owned for future ADS purposes, even if no ADS arose when they were acquired.
- A single transaction for six or more separate dwellings is treated as non-residential, so ADS does not apply, and MDR cases may require dwelling-by-dwelling analysis where ADS applies only to some properties.
