Examples of Stamp Duty Land Tax Provisions for Contracts After 10th July 2003

SDLT treatment of sub-sales where the property is transferred straight to the final buyer

This rule covers a narrow SDLT point. HMRC’s example shows that if an original buyer enters into a land contract, the contract is substantially performed, the buyer then sells on their interest, and the property is later transferred directly to the final buyer, the final transfer does not itself create an SDLT charge for the original buyer if the sub-sale rules apply.

• The rule applies to certain contracts made on or after 10 July 2003.
• HMRC’s example involves a contract, substantial performance before completion, a later sub-sale, and a direct conveyance to the ultimate purchaser.
• On those facts, the original contracting buyer is not charged SDLT just because the property is eventually conveyed to the final buyer.
• This does not mean there is no SDLT anywhere in the transaction; it only deals with the effect of the final conveyance on the original buyer.
• Substantial performance and the later conveyance should be analysed separately, as they can have different SDLT consequences.
• These cases are highly timing-sensitive, so the sequence of contract, possession, onward sale, and completion is important.

SDLT and sub-sales: when the original buyer is not charged on completion to the ultimate purchaser

This page explains a narrow SDLT point about sub-sales under the transitional rules for contracts made on or after 10 July 2003. The practical message from the official example is that, in the circumstances described, the original buyer is not charged SDLT simply because the property is eventually conveyed to the final buyer.

What this rule is about

The issue is what happens where:

• a land contract is entered into,
• that contract is substantially performed before formal completion,
• the original buyer then sells on their interest to someone else, and
• the property is ultimately transferred directly to that final buyer.

In SDLT, sub-sale rules can alter who is treated as acquiring the property for charge purposes. This matters because without those rules there could be a risk of taxing the intermediate buyer when, in substance, they do not end up taking the property by conveyance.

What the official source says

The HMRC manual gives this example:

• a contract is made on 1 August 2003,
• it is substantially performed on 1 September 2003,
• the original buyer sub-sells on 1 November 2003, and
• the contract is completed by a conveyance directly to the ultimate purchaser on 1 January 2005.

HMRC’s stated conclusion is that there is no SDLT charge on the original contracting purchaser. The reason given is the sub-sale rule: completion by conveyance to the ultimate purchaser does not trigger a charge on that original purchaser.

What this means in practice

The point of the example is quite specific. It is not saying that no SDLT arises anywhere in the transaction. It is saying that the later direct conveyance to the final buyer does not itself create an SDLT charge on the intermediate buyer who originally contracted to buy.

That is important because the timeline includes substantial performance before the sub-sale. In SDLT, substantial performance can itself be a chargeable event. But this example is focused on a different question: whether the eventual completion by conveyance to the final buyer triggers a charge on the original buyer. HMRC says it does not.

So, where the facts fit the sub-sale rule, the original buyer is not treated as becoming chargeable merely because legal title is later transferred directly to the ultimate purchaser.

How to analyse it

If you are looking at a similar transaction, the key questions are:

• Was there an original land contract?
• When was that contract entered into?
• Was it substantially performed before completion?
• Did the original buyer enter into a genuine sub-sale or onward sale?
• Was the property ultimately conveyed directly to the final purchaser rather than to the original buyer?
• Does the sub-sale rule apply to prevent the conveyance from triggering a charge on the original buyer?

The official example answers only that last point. It shows that, on those facts, direct completion to the final purchaser does not produce an SDLT charge on the original contracting purchaser.

It is also sensible to keep separate:

• any SDLT consequences of substantial performance, and
• any SDLT consequences of the later conveyance.

The example deals with the effect of the later conveyance, not every possible SDLT consequence arising earlier in the chain.

Example

Illustration: A agrees to buy land from B under a contract dated 1 August 2003. A takes possession on 1 September 2003, so the contract is substantially performed. Before legal completion, A agrees to sell on to C on 1 November 2003. On 1 January 2005, B transfers the land directly to C.

On HMRC’s example, that direct transfer to C does not trigger an SDLT charge on A. The sub-sale rule prevents A being charged merely because the original contract is completed by a conveyance to C.

Why this can be difficult in practice

Sub-sale cases are often timing-sensitive. A small change in sequence can affect the SDLT analysis. It also matters exactly what was sold on, and whether the arrangements fall within the relevant sub-sale provisions.

The example is brief and does not attempt to explain every consequence of substantial performance or every condition for the sub-sale rule to apply. So it should be read as illustrating one outcome on one set of facts, not as a complete statement of the law for all onward sale structures.

Another common difficulty is assuming that if the intermediate buyer is not charged on the final conveyance, there is no SDLT issue at all. That does not follow from this example. The example only addresses the absence of a charge on the contracting purchaser on completion by conveyance to the ultimate purchaser.

Key takeaways

• Where the sub-sale rule applies, a direct conveyance to the ultimate purchaser does not itself trigger an SDLT charge on the original contracting purchaser.
• The example is specifically about the effect of the final conveyance, not all possible SDLT consequences of the wider transaction.
• In sub-sale cases, the timing of contract, substantial performance, onward sale, and final completion is critical.
