Guidance on LBTT Sub-Sale Development Relief for First Buyer in Land Transactions

LBTT Sub-sale Development Relief in Scotland

LBTT sub-sale development relief can reduce or remove tax on the first land transaction where the first buyer sub-sells all or part of the land as part of a genuine development arrangement. It only applies if strict conditions are met, including linked timing between the contracts, strong evidence that significant commercial development will be completed within five years, and careful calculation where only part of the land is sub-sold.

• The relief is only available to the first buyer, not to later buyers in a chain, and it cannot be used if alternative property finance relief is claimed on the same transaction.
• A qualifying sub-sale requires the first buyer to sub-sell all or part of the same land interest and the second buyer must become entitled to call for a conveyance of that land.
• The first contract and the qualifying sub-sale must be substantially performed or completed at the same time and in connection with each other.
• Significant commercial development must be completed within five years; minor works or simple refurbishment will usually not be enough.
• Full relief may apply if the whole property is sub-sold, while partial relief needs a just and reasonable apportionment of the original consideration.
• If the expected development does not happen, the relief can be withdrawn and the first buyer must file a further LBTT return within 30 days and pay any extra tax due.

LBTT sub-sale development relief: when the first buyer can reduce tax in a development sub-sale

This page explains sub-sale development relief under Land and Buildings Transaction Tax in Scotland. The relief is aimed at certain land transactions where the first buyer acquires land and then sub-sells all or part of it in arrangements linked to significant development. It matters because, if the conditions are met, the first buyer can reduce or eliminate LBTT on the first transaction. But the conditions are technical, the timing is important, and the relief can later be withdrawn if the expected development does not happen.

What this rule is about

In an ordinary sub-sale, one buyer contracts to buy land and, before completion, enters into another contract so that another person can take the land instead. Schedule 10A to the LBTT legislation creates a special relief where that sub-sale is connected with significant development.

The relief is narrowly targeted. It is only for the first buyer in the chain. It is not available to a second or later buyer in a series of sub-sales. It is also not available if relief for alternative property finance is being claimed on the same transaction.

The policy behind the relief is that, in some development structures, charging LBTT in full on the first transaction may not reflect the commercial reality where the land is being passed on as part of a development arrangement. But the legislation only gives that treatment where there is a genuine qualifying sub-sale and real, significant development is expected within a set period.

What the official source says

Revenue Scotland’s guidance says the relief is available where:

• the first buyer acquires a chargeable interest under a first contract completed by conveyance,
• there is a qualifying sub-sale, and
• the qualifying conditions are met.

A sub-sale is a qualifying sub-sale if, under it:

• the first buyer contracts to sell all or part of the subject-matter of the first contract to a second buyer,
• the second buyer becomes entitled to call for a conveyance of that whole or part, and
• immediately before entering into the sub-sale, the first buyer was entitled under the first contract to call for a conveyance of that same whole or part.

The key qualifying conditions include:

• the substantial performance or completion of the first contract must take place at the same time as, and in connection with, the substantial performance or completion of the qualifying sub-sale, and
• significant development for commercial purposes of the subject-matter must be completed within five years from the date the first buyer entered into the qualifying sub-sale.

The guidance also explains that a normal LBTT rule on substantial performance in section 14(1)(c) is disapplied for qualifying cases by paragraph 16 of schedule 10A. That matters because, in an ordinary sub-sale, the second buyer becoming entitled to call for a conveyance can trigger substantial performance on the first contract. Schedule 10A is intended to switch that effect off where the sub-sale qualifies for this relief.

Revenue Scotland defines development widely enough to include the construction of educational, sports and leisure, residential, retail, office and industrial buildings, and redevelopment of such buildings where the redevelopment is comparable in scale and cost to new construction. It excludes agricultural buildings, mining or engineering works other than wind farms, and plant and machinery.

The guidance also says that “significant development” must be judged by reference to the nature and extent of the subject-matter and its market value. It is not intended to cover simple refurbishment of an existing building, or only minor development compared with the land involved.

What this means in practice

The relief is mainly relevant where a land deal is structured in two stages:

• first, Buyer B contracts with Seller A, and
• before that deal is completed, Buyer B enters into a sub-sale with Buyer C.

If C becomes entitled to call for a conveyance, and the other conditions are met, B may be able to claim sub-sale development relief on the first transaction.

There are two broad outcomes:

• full relief, where the qualifying sub-sale covers the whole subject-matter of the first contract, and
• partial relief, where the qualifying sub-sale covers only part of the first contract.

For full relief, the first transaction can be relieved in full.

For partial relief, the first transaction is recalculated. The legislation uses an apportionment formula:

• start with the chargeable consideration for the first transaction if there were no sub-sale, and
• subtract the amount of that consideration that is just and reasonably attributable to the part that is also the subject-matter of the qualifying sub-sale.

The qualifying sub-sale itself then has its own chargeable consideration calculation. That includes:

• any consideration under the first transaction that is attributable to the qualifying sub-sale and is given directly or indirectly by the second buyer, or by someone connected with the second buyer, and
• the consideration given for the qualifying sub-sale itself.

In practical terms, the second buyer may be funding part of the price payable to the original seller, may be paying an additional premium to the first buyer, or both. The legislation is designed to capture the real economic consideration moving in the arrangement.

The first buyer claims the relief in the LBTT return for the first transaction, or by amending that return within the amendment period. At the time of the claim, evidence must be available to support the expectation that significant development will take place. Revenue Scotland gives examples such as plans, funding arrangements, building contracts and planning applications.

This is not a “claim now and think later” relief. If the expected significant development does not happen within five years, the relief is withdrawn in full or in part, and the first buyer must file a further LBTT return within 30 days after the end of that five-year period and pay any additional tax due.

How to analyse it

A sensible way to analyse the relief is to work through the following questions.

• Who is the claimant? The relief is only for the first buyer. If you are looking at a later buyer in a chain, this relief is not available.
• Is there a true first contract and a separate sub-sale? The “first contract” does not include a contract that is itself a sub-sale or an assignation of rights under another contract.
• Has the second buyer become entitled to call for a conveyance of all or part of the same land interest? If not, the sub-sale may not be a qualifying sub-sale.
• Was the first buyer entitled, immediately before the sub-sale, to call for a conveyance under the first contract? This links the first contract and the sub-sale in the way the legislation requires.
• Do the timing conditions work? The substantial performance or completion of the first contract must take place at the same time as, and in connection with, the substantial performance or completion of the qualifying sub-sale.
• What exactly is the “subject-matter” of the qualifying sub-sale? This matters for deciding whether full or partial relief applies and for any apportionment.
• Is the planned work really “significant development for commercial purposes”? This is one of the most important judgement points.
• Will that significant development be completed within the relevant five-year period?
• Is there enough evidence, at the time of the claim, to support the expectation of significant development?
• Could another relief, such as alternative property finance relief, prevent this relief from applying?

Where only part of the land is sub-sold, careful apportionment is essential. The guidance repeatedly uses a “just and reasonable” basis. That means the figures should reflect the commercial and factual reality of the part affected by the qualifying sub-sale, rather than an arbitrary split.

Example

This is an illustration of how the relief can work.

A developer, B, contracts to buy a large commercial site from A. Before completion, B enters into a sub-sale with C for part of the site. Under that sub-sale, C becomes entitled to call for a conveyance of that part. The completion arrangements for the A-to-B contract and the B-to-C sub-sale are linked and happen together. At that stage there are detailed development plans, funding arrangements and building contracts showing that substantial commercial redevelopment of the part acquired by C is expected and will be completed within five years.

On those facts, B may be able to claim partial sub-sale development relief on the first transaction. LBTT on the first transaction would then be recalculated by removing, on a just and reasonable basis, the consideration attributable to the part that is the subject of the qualifying sub-sale. The sub-sale transaction would then be taxed on its own chargeable consideration under the schedule 10A rules.

If, five years later, the planned significant development has not taken place, the relief may be withdrawn in whole or in part. B would then need to file a further LBTT return and pay the additional tax due.

Why this can be difficult in practice

The hardest issues are usually not the existence of a sub-sale, but whether the statutory conditions are really met.

First, “significant development” is fact-sensitive. The guidance says significance must be judged against the nature, extent and market value of the land. That means there is no simple universal test. Work that is significant for one site may be minor for another. Refurbishment of an existing building is specifically flagged as outside the intended scope where it is not comparable in scale and cost to new construction.

Second, the timing rules are technical. The guidance notes that there can be a difference between the date the first buyer enters into the sub-sale and the point at which the arrangement becomes a “qualifying sub-sale” for the purposes of the legislation. It also notes that the five-year “relevant period” can begin from the date of substantial performance or completion of both contracts, rather than the date the contract was first entered into, if the contract only becomes a qualifying sub-sale later. That means the dates should be checked carefully against the statutory conditions, not assumed.

Third, partial relief requires just and reasonable apportionment. That can be straightforward where the sub-sold part is clearly identifiable and separately valued, but harder where the site is integrated, where infrastructure benefits the whole development, or where consideration is paid indirectly.

Fourth, the interaction with substantial performance rules can be counter-intuitive. In ordinary LBTT analysis, a sub-sale can trigger substantial performance of the first contract when the later buyer becomes entitled to call for a conveyance. Schedule 10A can disapply that result, but only where the relief would otherwise be available. So the relief conditions need to be tested carefully before assuming the normal rule has been switched off.

Finally, evidence matters both at the start and at the end. At the time of the claim, there must be material showing that significant development will take place. If the development later falls short, records will also be needed to support any partial withdrawal calculation.

Key takeaways

• Sub-sale development relief is only for the first buyer in a qualifying development sub-sale arrangement.
• The relief depends on a genuine qualifying sub-sale, linked timing of the transactions, and significant commercial development being completed within five years.
• If the development does not happen as expected, the relief can be withdrawn and the first buyer must file a further LBTT return and pay the extra tax due.
