Buying Scottish residential property through a company can be commercially attractive in some cases, particularly for landlords building a portfolio, investors who want profits retained in a corporate structure, or families considering succession and asset protection. However, for Land and Buildings Transaction Tax (LBTT) purposes, a company purchase is often more expensive than expected. The key point is that Scottish LBTT has its own Additional Dwelling Supplement (ADS) rules, and those rules treat companies much more harshly than many individual first-time landlords expect.
The Starting Point
LBTT applies to acquisitions of chargeable interests in land in Scotland. It replaced UK Stamp Duty Land Tax in Scotland from 1 April 2015 and is administered by Revenue Scotland. The statutory framework is primarily contained in the Land and Buildings Transaction Tax (Scotland) Act 2013 (the “Act”), with the ADS rules contained in Schedule 2A of the Act, which deals with the additional amount chargeable on certain residential transactions, including purchases by non-natural persons and acquisitions of additional dwellings.
For an ordinary residential purchase, LBTT is calculated using the residential rates and bands. If ADS applies, it is not a substitute for LBTT. It is an additional charge on top of the normal LBTT liability. Revenue Scotland’s guidance describes ADS as an additional charge added to any LBTT due when a buyer acquires an additional residential property in Scotland.
The Main Trap
A common misunderstanding is that ADS only applies where the buyer already owns another property. That is broadly how many individuals think about the rules, but it is not the right analysis for a company. Revenue Scotland’s guidance states that ADS applies to most purchases of residential property in Scotland by non-natural persons, including corporate bodies and companies, even where they have no other residential properties. This means a newly incorporated company buying its very first buy-to-let property in Scotland will normally pay ADS, provided the relevant consideration is £40,000 or more.
Example
Assume Aisha personally owns no residential property anywhere in the world and buys a Scottish flat for £250,000 as her first buy-to-let. If she is not buying in the course of a property investment or dealing business as a sole trader or partner, ADS should not apply where an individual buys a first buy-to-let and owns no other dwelling at the end of the effective date.
Now assume Aisha instead forms Aisha Property Ltd, and the company buys the same Scottish flat for £250,000. The company also owns no other property. ADS applies because the buyer is a company. The corporate structure has therefore created an immediate £20,000 acquisition tax cost that would not have arisen on the same facts if Aisha had bought personally as an individual with no other dwellings.
The Current ADS Rate Is 8%, Not 6%
For contracts entered into on or after 5 December 2024, the ADS rate is 8% of the purchase price. Revenue Scotland confirms that the previous 6% rate continues only in limited transitional cases, broadly where the contract was entered into on or before 4 December 2024.
On a £400,000 company purchase of a Scottish residential property, the standard residential LBTT would be £13,350. The ADS would be 8% of £400,000, which is £32,000. The total LBTT cost would therefore be £45,350. This is a significant upfront cost and should be factored into the investment yield calculation before deciding that a company purchase is tax efficient.
The £40,000 Threshold Is Not a General Planning Escape
ADS will not apply where the consideration payable for the property is less than £40,000. Revenue Scotland also notes that for transactions with an effective date from 1 April 2024, a share in a jointly owned property is only counted for ADS ownership purposes if the value of the buyer’s individual share is £40,000 or more.
This does not usually help a company buying a normal buy-to-let property, because most acquisitions will exceed £40,000. It is more relevant for unusual low-value transactions, transfers of small interests, or cases where existing jointly owned property interests need to be considered when applying the ADS ownership tests.
Joint Purchases with a Company Can Taint the Whole Transaction
Another point often missed is that buying jointly with a company can bring ADS into play even for an individual co-buyer who would not otherwise have paid it.
Example
Ben owns no property and wants to buy a £300,000 Scottish flat jointly with Ben Investments Ltd, perhaps because the company is providing part of the funds. If Ben had bought alone, ADS may not have applied. But because one buyer is a company, ADS applies to the transaction.
Companies Cannot Rely on Main Residence Replacement Relief
The main residence replacement rules are important for individuals. Where an individual buys a new main residence before selling their previous main residence, ADS may be payable upfront but can potentially be reclaimed if the previous main residence is sold within the statutory time limit and the other repayment conditions are met. For transactions with an effective date on or after 1 April 2024, Revenue Scotland refers to a 36-month period for the relevant main residence replacement rules.
A company, however, does not have an only or main residence in the ordinary sense. A non-individual is not regarded as replacing its only or main residence and that ADS therefore applies to every purchase of a dwelling in Scotland by a non-individual, subject to limited exceptions such as certain trust cases and specific reliefs.
This is a major practical difference. An individual buying a new home before selling the old one may have a route to repayment. A company buying a residential investment property normally does not have that route, because the purchase is not a replacement of a main residence.
Example
Consider Claire, who owns her current Scottish home and buys a new Scottish home for £500,000 before her existing home sale completes. She pays ADS because, at the end of the effective date, she owns two dwellings and has not yet replaced her previous main residence. If she sells the old main residence within the 36-month period and satisfies the occupation conditions, she may be able to reclaim the ADS.
Now compare Claire Property Ltd buying a £500,000 flat as a rental property. The company is not replacing a main residence. ADS applies from the outset and there is generally no later main residence sale that can generate a repayment claim. The company’s LBTT position is therefore not merely a timing issue. It is usually a permanent acquisition cost.
Six or More Dwellings Can Change the Analysis
There is a specific relief from ADS where a buyer purchases six or more separate dwellings in a single transaction. Revenue Scotland states that full relief from ADS is available for any transaction in which a buyer purchases six or more residential properties in one transaction. It also explains that where six or more separate dwellings are the subject of a single transaction involving the transfer of a major interest, they are treated as non-residential property.
Example
If a company buys a block of eight flats in one transaction for £1.2 million, the company may avoid ADS under the six-dwellings rule. The transaction would still require an LBTT calculation using non-residential rates, but ADS would not be due, a materially different outcome from buying five flats or buying eight flats across separate transactions each involving fewer than six dwellings.
Mixed-Use Property
Companies sometimes buy mixed-use property, such as a shop with a flat above it, licensed premises with residential accommodation, or a commercial building with staff accommodation. Revenue Scotland’s guidance states that ADS does not generally apply to non-residential property transactions, but it can apply in part where a transaction includes residential property. In such cases, the ADS is applied only to the consideration attributable to the residential purchase, provided that part is £40,000 or more.
Example
If a company buys licensed premises for £1 million and £200,000 is justly and reasonably attributable to a flat above the premises, ADS may apply to the £200,000 residential element. The commercial element should not itself be subject to ADS, but the apportionment must be supportable.
Multiple Dwellings Relief Does Not Automatically Remove ADS
Multiple Dwellings Relief (MDR) can reduce the LBTT cost where more than one dwelling is acquired, but it should not be confused with ADS relief. Where ADS is due and MDR is claimed, the calculation requires the tax due on each dwelling to be worked out and added together, with ADS applied to the dwellings to which it applies. This is important because some buyers assume that MDR and ADS relief are the same thing. They are not. MDR may reduce the ordinary LBTT element, but ADS can still be a substantial charge unless a specific ADS relief applies, such as the six or more dwellings rule.
Buying Through a Company Is Not Automatically Wrong
The fact that ADS applies does not mean that a company should never be used to purchase a residential property. A company may still be appropriate where the investor is building a long-term portfolio, expects to retain profits within the company, wants corporate limited liability, or needs a corporate structure for commercial financing or joint venture reasons. For UK tax purposes more generally, companies may also offer different treatment for finance costs and profit extraction, although those issues need to be modelled separately from LBTT.
Conclusion
For a Scottish residential investment purchase, a company will usually suffer ADS even if it is buying its first property. That is the point most often missed. Individuals may escape ADS on a first dwelling, may benefit from main residence replacement rules, and may have repayment routes in delayed-sale cases. Companies generally do not have those advantages. The decision should therefore be made by modelling the whole position. That means comparing the personal and company routes after taking account of standard LBTT, ADS, mortgage terms, corporation tax, income tax on extraction, future capital gains or corporation tax on sale, legal costs, accounting costs and succession objectives. From an LBTT and ADS perspective alone, the company route often starts at a disadvantage. It may still be justified, but it should not be chosen without first pricing in the Scottish ADS cost.
