Stamp Duty Land Tax Relief for Property Traders in Broken Transaction Chains

SDLT relief for property traders in broken home sale chains

This SDLT relief can apply when a property trader buys an individual’s existing home after that person’s planned sale falls through, so they can still complete the purchase of a new main home. Full relief is available only if strict conditions are met, and it may be reduced or withdrawn in some cases.

• The relief is aimed at genuine broken-chain cases, not ordinary purchases by property traders.
• The seller must be an individual whose old home was their only or main residence at some point in the previous two years, and they must intend to live in the new property as their main home.
• The failed sale and the trader’s purchase must be linked: the trader must buy the old home to allow the seller’s onward purchase to proceed.
• The buyer must be acting in a qualifying property trading business that includes buying homes in these chain-break circumstances.
• If the land bought is larger than the permitted area, only partial relief may be available and SDLT may still be due on part of the price.
• The relief can later be withdrawn if the trader spends too much on refurbishment, grants occupation rights inappropriately, or allows connected persons to occupy the property, although a short licence back to the seller for up to six months is allowed.

SDLT relief where a property trader buys a home after a sale falls through

This relief can apply when a person is trying to move home, their planned sale collapses, and a property trader steps in to buy their existing home so the onward purchase can still go ahead. If the conditions are met, the trader’s purchase can be exempt from SDLT, or partly relieved if too much land is included.

What this rule is about

The rule deals with a specific type of broken property chain. It is aimed at cases where an individual has arranged to sell their current home and buy another one, but the sale of the current home fails. A property trader may then buy that home to rescue the transaction chain and allow the individual’s purchase of the new home to proceed.

Schedule 6A paragraph 4 Finance Act 2003 gives relief from SDLT for that acquisition if the statutory conditions are satisfied. The relief is focused on genuine chain-break situations involving an individual’s home. It is not a general relief for all purchases by property traders.

What the official source says

HMRC’s manual says the trader’s purchase of the old dwelling is exempt from SDLT if all of the following apply:

• The property trader buys a dwelling from an individual, whether alone or jointly with other individuals.
• The individual had made arrangements both to sell that old dwelling and to acquire another dwelling.
• The arrangements to sell the old dwelling fail.
• The trader’s purchase is made to enable the individual’s purchase of the other dwelling to proceed.
• The trader makes the purchase in the course of a business that consists of, or includes, acquiring dwellings from individuals in these circumstances.
• The individual occupied the old dwelling as their only or main residence at some point in the two years before the trader’s purchase.
• The individual intends to occupy the other dwelling as their only or main residence.
• The land acquired does not exceed the permitted area.

If the land acquired is larger than the permitted area, the relief is not necessarily lost altogether. Partial relief may be available if the other conditions are met. In that case, part of the consideration remains chargeable to SDLT.

HMRC also says the relief is withdrawn if the trader:

• spends more than the permitted amount on refurbishment of the old dwelling
• grants a lease or licence of the old dwelling
• allows any of its principals or employees, or persons connected with them, to occupy the old dwelling

There is an important exception to the lease or licence point. The relief is not denied or withdrawn merely because the trader intends to grant, and then grants, a lease or licence back to the individual for no more than six months after acquiring the old dwelling.

HMRC directs readers to its definitions page for the detailed meaning of terms such as property trader, permitted area, permitted amount, and related criteria. It also says relief is claimed on the SDLT return using relief code 28.

What this means in practice

The relief is aimed at a narrow commercial situation. A trader who operates in the business of buying homes from individuals whose sales have collapsed may be able to buy without SDLT, provided the purchase is genuinely part of rescuing the individual’s onward move.

The key practical point is that the trader is not just buying any residential property from any seller. The purchase must be tied to a failed sale of the seller’s existing home and must be made so that the seller can still complete their purchase of a replacement home.

The seller must also be an individual, and the old dwelling must have been their only or main residence at some point in the previous two years. The replacement property must be intended to become their only or main residence.

The land area matters. If the trader acquires more than the permitted area, full relief is not available. Instead, SDLT is charged on the excess element by comparing the market value of the permitted area with the market value of the whole property acquired.

The relief can also be lost later. So even if the trader qualifies at completion, later actions can trigger withdrawal. In particular, the trader must be careful about refurbishment spending, granting occupation rights, or allowing occupation by connected persons. The short-term licence back to the seller for up to six months is specifically allowed.

How to analyse it

A sensible way to test the relief is to work through the conditions in order:

• Who is the seller? The seller must be an individual, whether acting alone or with other individuals.
• What was the seller trying to do? There must have been arrangements to sell the old dwelling and buy another dwelling.
• Did the sale fail? The earlier sale arrangements must have broken down.
• Why is the trader buying? The purchase must be for the purpose of enabling the seller’s acquisition of the other dwelling to proceed.
• Is the buyer a qualifying property trader? The acquisition must be in the course of a business that includes buying dwellings from individuals in these chain-break circumstances.
• Was the old dwelling the seller’s home? The individual must have occupied it as their only or main residence at some time in the two years before the trader’s purchase.
• Will the new dwelling be their home? The individual must intend to occupy the replacement dwelling as their only or main residence.
• How much land is included? If it exceeds the permitted area, consider partial relief instead of full relief.
• Could the relief later be withdrawn? Review any planned refurbishment, occupation arrangements, or licences carefully.

In practice, the evidence behind the purpose and timing of the transaction is likely to matter. A conveyancer or adviser would usually want to see the failed sale arrangements, the onward purchase arrangements, and the reason the trader stepped in.

Example

An individual agrees to sell their home and buy another house to live in. Shortly before exchange or completion, the buyer of their existing home pulls out. A specialist property trader then buys the existing home so that the individual can still complete the purchase of the new house.

If the old home had been the individual’s main residence within the previous two years, the individual intends to live in the new house as their main residence, the trader is carrying on the relevant business, and the land acquired does not exceed the permitted area, the trader’s purchase may qualify for relief.

If the trader also allows the individual to stay in the old home for a short period under a licence of no more than six months after completion, that alone does not prevent the relief.

Why this can be difficult in practice

The statutory conditions are quite specific, and some are fact-sensitive.

First, purpose matters. The trader’s purchase must be made to enable the individual’s purchase of the other dwelling to proceed. That may be straightforward in a clear chain-break case, but less so if there were several reasons for the purchase or if the onward purchase was uncertain.

Second, this relief depends on defined terms such as property trader, permitted area, and permitted amount. HMRC’s manual page here refers readers elsewhere for those definitions. So the outcome may depend on technical rules not set out in this extract.

Third, later events can claw back the relief. That means the analysis does not end on completion. The trader’s post-completion conduct must also be checked.

Fourth, where excess land is involved, the relief becomes only partial. The chargeable amount is based on market value comparisons, which may require valuation evidence.

Key takeaways

• This is a targeted SDLT relief for a property trader buying a home from an individual after a sale falls through and the onward purchase needs to be rescued.
• The seller’s old dwelling must have been their only or main residence within the previous two years, and they must intend to live in the replacement dwelling as their only or main residence.
• Full relief can be lost or reduced if too much land is acquired, or withdrawn later if the trader refurbishes beyond the permitted amount or allows occupation in disallowed ways.
