Overview of Multiple Dwellings Relief and Changes Effective from June 2024

Multiple Dwellings Relief for SDLT: abolition, scope and practical points

Multiple Dwellings Relief (MDR) was a former SDLT relief for buying more than one dwelling in a single or linked transaction, but it was abolished for transactions completing or being substantially performed on or after 1 June 2024, subject to transitional rules. It now mainly matters for older transactions and cases near the changeover date, where timing, the type of property acquired, and whether MDR was better than other SDLT treatment all need careful review.

• MDR had to be claimed and was not automatic; it worked by calculating SDLT on the average price per dwelling, with a minimum SDLT rate of 1% on the dwelling element.
• If a transaction included both dwellings and other land, MDR only applied to the part of the price attributable to the dwellings, while the rest was taxed under the normal rules.
• Where six or more dwellings were bought in one transaction, the buyer could sometimes choose non-residential SDLT treatment instead, so both methods should be compared.
• MDR could still apply even if the higher rates for additional dwellings or the non-resident surcharge also applied, because those surcharges were built into the calculation.
• Some interests were excluded, including certain superior freehold or leasehold interests where the dwelling was already subject to a lease with an initial term of 21 years or more, unless an exception applied.
• Practical difficulties often arose over timing, substantial performance, off-plan contracts, mixed property apportionment, and later changes if the number of dwellings fell within three years.

Multiple Dwellings Relief for SDLT: what it was, when it could apply, and why timing now matters

This page explains the former SDLT relief known as Multiple Dwellings Relief, usually called MDR. The relief has been abolished for transactions that complete, or are substantially performed, on or after 1 June 2024, subject to transitional rules. That means MDR is now mainly relevant for older transactions and for cases where timing falls within the transitional provisions. The key question is often not just whether more than one dwelling is involved, but whether the transaction happened early enough, whether the right type of property was acquired, and whether claiming MDR is actually better than the alternative SDLT treatment.

What this rule is about

MDR was a relief designed to reduce SDLT where a purchaser acquired more than one dwelling in a transaction, or in linked transactions. Instead of applying residential SDLT rates to the total price in the usual way, the tax on the dwelling element was worked out by looking at the average price per dwelling. This could produce a lower SDLT result, especially where several lower-value dwellings were bought together.

The relief was not automatic. A purchaser had to claim it. It also sat alongside another important rule: where six or more dwellings were bought in a single transaction, the purchaser could in some cases choose to treat the purchase as non-residential under section 116(7) Finance Act 2003. In practice, the purchaser could compare the two routes and use whichever gave the lower SDLT liability, if both were available.

What the official source says

HMRC’s manual says MDR has been abolished for transactions completing, or substantially performed, on or after 1 June 2024. It also points to special transitional rules, including special rules for linked transactions.

Where MDR is claimed, the SDLT rate for the consideration attributable to dwellings is determined by dividing that consideration by the number of dwellings. SDLT is then calculated by reference to that average amount. The relief is subject to a minimum rate of 1%.

If part of the transaction relates to land that is not a dwelling, the SDLT treatment of that non-dwelling element is worked out as it would be without MDR.

The manual also says that superior freehold or leasehold interests in dwellings subject to leases granted for an initial term of 21 years or more are not eligible for MDR, except in certain shared ownership cases.

MDR included special treatment for some off-plan purchases. HMRC says this covers a purchase of a dwelling that is to be constructed, where construction has not yet started when the contract is substantially performed. HMRC distinguishes this from buying bare land with planning permission but without an obligation to build a dwelling. On HMRC’s view, MDR could apply to the first case but not the second.

The manual further states that the tax calculation may need to be adjusted if the number of dwellings involved is reduced within three years of the effective date of the transaction.

Finally, HMRC says MDR could still apply where the higher rates for additional dwellings applied, and also where the non-resident surcharge applied. In those cases, the relevant higher rates were taken into account when applying the average-consideration calculation.

What this means in practice

The first practical point is timing. For most current transactions, MDR is no longer available. If the effective date is on or after 1 June 2024, the starting point is that MDR has been abolished. But that is not always the end of the matter, because transitional rules may preserve relief in some cases. If a transaction sits around the changeover date, you need to check the transitional rules carefully.

The second point is that MDR was elective. If it was available, the purchaser had to claim it. It did not arise automatically just because multiple dwellings were bought.

The third point is that MDR did not simply apply to the whole price without distinction. You first had to identify the consideration attributable to dwellings. The averaging method applied to that part. Any consideration attributable to non-dwelling land was dealt with under the ordinary rules.

The fourth point is that buying multiple dwellings did not always mean MDR was the best answer. If six or more dwellings were acquired in a single transaction, the purchaser might instead choose non-residential treatment under section 116(7). The manual makes clear that, where both routes were open, the purchaser could choose whichever was more SDLT-efficient.

The fifth point is that MDR could still be relevant even where SDLT surcharges applied. If the higher rates for additional dwellings applied, or if the non-resident surcharge applied, that did not prevent MDR. Instead, those higher rates were built into the rate applied to the average consideration.

How to analyse it

A sensible way to analyse an MDR issue is to work through these questions in order:

• What is the effective date of the transaction? If completion or substantial performance was on or after 1 June 2024, check whether abolition applies and whether any transitional rule preserves MDR.
• How many dwellings are being acquired? MDR only mattered where more than one dwelling was involved.
• Is the subject matter actually a dwelling, or a right relating to a dwelling, for MDR purposes? This can be especially important for off-plan arrangements and long lease structures.
• Is any part of the property non-residential or mixed? If so, separate the dwelling element from the rest, because MDR only affects the dwelling element.
• Is the purchaser acquiring six or more dwellings in a single transaction? If yes, compare MDR with possible non-residential treatment under section 116(7).
• Do the higher rates for additional dwellings apply? If yes, factor them into the MDR calculation rather than assuming they block the relief.
• Does the non-resident surcharge apply? If yes, that also feeds into the rate calculation.
• Is the interest excluded because it is a superior interest in a dwelling subject to a lease with an initial term of 21 years or more, unless an exception applies?
• Could the number of dwellings change within three years? If so, bear in mind that the SDLT calculation may later need adjustment.

Example

Illustration: a purchaser exchanges contracts to buy several completed flats in one transaction. The effective date falls before 1 June 2024, so MDR is still potentially in point. The purchaser can choose to claim MDR, in which case the SDLT rate on the dwelling consideration is worked out by reference to the average price per flat, subject to the 1% minimum rate. If the purchase is of six or more flats in a single transaction, the purchaser may also be able to choose non-residential treatment instead. The practical task is to compare the two calculations and use the one that produces the lower SDLT bill, if both are legally available.

By contrast, if the purchaser merely buys bare land with planning permission for homes, and there is no obligation under the contract for dwellings to be built, HMRC’s view in the manual is that this is not the kind of off-plan purchase that qualified for MDR.

Why this can be difficult in practice

The hardest cases are often about classification and timing.

Timing can be difficult because the manual refers not only to completion, but also to substantial performance. A transaction may have an effective date earlier than formal completion. Around 1 June 2024, that can be decisive for whether MDR survived abolition.

Classification can also be difficult. The manual draws a line between an off-plan purchase of a dwelling to be constructed, and the purchase of bare land with planning permission but no obligation to build. In practice, contracts do not always fit neatly into one category. The exact contractual rights and obligations matter.

Another difficult area is deciding what counts as the dwelling element where the transaction includes other land or rights. MDR only changes the tax treatment of consideration attributable to dwellings. That requires a defensible analysis of what part of the price relates to dwellings and what part does not.

There can also be post-transaction risk. If the number of dwellings is reduced within three years of the effective date, the SDLT calculation may need to be revisited. So the original claim may not be the end of the story.

Finally, purchasers sometimes assume that MDR and the higher rates are mutually exclusive. The manual says they are not. The surcharges may still apply, but they are folded into the rate used for the average-consideration method.

Key takeaways

• MDR has been abolished for transactions completing, or substantially performed, on or after 1 June 2024, unless transitional rules preserve it.
• Where MDR was available, it had to be claimed and it worked by applying SDLT rates to the average consideration per dwelling, subject to a 1% minimum rate.
• For purchases of six or more dwellings in a single transaction, it was often necessary to compare MDR with possible non-residential treatment and choose the more favourable result.
