Example 9: SDLT Relief for Multiple Dwellings and Non-Residential Property Purchase

Multiple dwellings relief for mixed purchases with non-residential land

When a property purchase includes several dwellings as well as non-residential land or buildings, the total price must be split between the residential and non-residential parts before SDLT is calculated. Multiple dwellings relief applies only to the amount attributed to the dwellings, while the non-residential part is taxed separately under non-residential SDLT rules.

• You cannot apply multiple dwellings relief to the whole purchase price if part of the transaction is non-residential.
• The key steps are to identify the dwellings, decide what is non-residential, count the number of dwellings, and apportion the price between the two parts.
• In HMRC’s example, a £12 million estate purchase included 13 dwellings, with £8 million allocated to the dwellings and £4 million to farmland and farm buildings.
• The £8 million residential element is divided by 13 to find the average price per dwelling for the multiple dwellings relief calculation, and the result is then multiplied back across all dwellings.
• The £4 million attributed to farmland and farm buildings is excluded from the relief calculation and taxed at non-residential SDLT rates.
• In practice, the main areas of difficulty are deciding what counts as a dwelling and agreeing a fair split of the purchase price; extra charges such as the non-resident surcharge may also need to be considered.

Multiple dwellings relief where a purchase includes both dwellings and non-residential land

This page explains how multiple dwellings relief can work when one transaction includes several dwellings as well as non-residential property such as farmland or farm buildings. The point matters because the residential part and the non-residential part are not taxed in the same way, and the purchase price must be split between them before SDLT is worked out.

What this rule is about

Some land transactions include more than one type of property. A buyer may acquire houses or flats, but also agricultural land, commercial buildings, yards, woodland, or other land that is not residential property for SDLT purposes.

Where a single transaction includes multiple dwellings, multiple dwellings relief may apply to the residential element. But that does not mean the whole purchase is treated as residential. If part of the property is non-residential, that part must still be dealt with under the non-residential SDLT rules.

The source material gives an example of a large estate purchase containing a main house, estate cottages or flats, farm buildings, and farmland. It shows how to separate the consideration and apply the correct tax treatment to each part.

What the official source says

HMRC’s example involves the purchase of a freehold estate for £12,000,000. The estate includes:

• a mansion, stable block and four acres of gardens, treated together as one dwelling,
• twelve further flats and houses for domestic and estate workers,
• farm buildings, and
• fifty acres of farmland.

That means the transaction includes 13 dwellings in total.

HMRC says the consideration must be attributed between:

• the dwellings: £8,000,000, and
• the farm buildings and farmland: £4,000,000.

For the dwellings element, the SDLT rate is determined by dividing the dwellings consideration by the number of dwellings. In the example, £8,000,000 divided by 13 gives £615,385 per dwelling. SDLT is calculated on that figure and then multiplied by 13.

For the non-residential element, the £4,000,000 attributed to the farm buildings and farmland is taxed using non-residential SDLT rates.

The source also notes that the non-resident rates of SDLT may apply if any purchaser is not UK resident.

What this means in practice

The practical message is that you cannot simply apply multiple dwellings relief to the whole purchase price if the transaction includes non-residential property as well.

Instead, you need to do three things:

• identify how many dwellings are being acquired,
• split the total consideration between the dwellings and the non-residential property, and
• apply the correct SDLT rules to each part.

In HMRC’s example, the mansion and its stable block and gardens are treated as part of a single dwelling. That matters because the number of dwellings affects the averaging calculation under multiple dwellings relief. If something is part of one dwelling rather than a separate dwelling, it does not increase the dwelling count.

The farmland and farm buildings are treated as non-residential property. So the £4,000,000 attributed to them is not included in the multiple dwellings relief calculation. It is taxed separately using non-residential rates.

This can materially affect the SDLT result. A buyer may get the benefit of averaging for the dwellings, but not for the non-residential land.

How to analyse it

A sensible way to approach this type of transaction is:

• First, identify every part of the property being acquired.
• Second, decide which parts are dwellings and which parts are non-residential property for SDLT purposes.
• Third, check whether some land or buildings should be treated as part of a dwelling rather than separately. In the example, the mansion, stable block and gardens are treated as one dwelling.
• Fourth, count the total number of dwellings included in the transaction.
• Fifth, apportion the total purchase price between the dwellings and the non-residential property.
• Sixth, apply the multiple dwellings relief calculation only to the consideration attributed to the dwellings.
• Seventh, calculate SDLT on the non-residential part using non-residential rates.
• Eighth, consider whether any additional residential charging rules apply, including the non-resident surcharge if relevant.

The key judgement points are usually the dwelling count and the price apportionment. Those two issues often drive the SDLT outcome.

Example

Illustration based on HMRC’s example:

A buyer acquires an estate for £12,000,000. The estate includes 13 dwellings in total, plus farm buildings and farmland. Of the total price, £8,000,000 is attributed to the dwellings and £4,000,000 to the non-residential property.

The buyer applies multiple dwellings relief to the £8,000,000 residential element only. That amount is divided by 13, giving £615,385. SDLT is worked out on £615,385 and then multiplied by 13.

The separate £4,000,000 attributed to farm buildings and farmland is taxed using non-residential rates.

The result is a combined SDLT computation made up of:

• the tax on the dwellings element under the multiple dwellings relief method, and
• the tax on the non-residential element under non-residential rates.

Why this can be difficult in practice

The official example is short, but real transactions are often less clear-cut.

One difficulty is deciding what counts as a dwelling. Staff accommodation, cottages, annexes, converted outbuildings, and estate buildings may not always be straightforward. The source example assumes that the mansion, stable block and gardens together form part of one dwelling, but that conclusion depends on the facts.

Another difficulty is apportioning the price. HMRC’s example simply states that £8,000,000 is attributed to the dwellings and £4,000,000 to the non-residential property. In practice, that attribution can be contentious if the contract does not provide a reliable split or if the values are not obvious.

A further point is that the source refers to the non-resident rates potentially applying if a purchaser is not UK resident. That means the residential part of the transaction may be affected by additional charging rules beyond the basic multiple dwellings relief calculation.

So although the example looks mechanical, the underlying classification and valuation work can be fact-sensitive.

Key takeaways

• Where one transaction includes multiple dwellings and non-residential property, the consideration must be split between them.
• Multiple dwellings relief applies to the dwellings consideration, not automatically to the whole purchase price.
• Farm buildings and farmland are taxed separately using non-residential SDLT rates if they are non-residential property.
