Sub-Sale Development Relief in LBTT: A Practical Guide for Property Transactions

Sub-sale relief under the Land and Buildings Transaction Tax (Scotland) Act 2013 (the “Act”) operates differently from equivalent provisions in England and Wales. While Stamp Duty Land Tax (SDLT) and Land Transaction Tax (LTT) provide broad relief for sub-sale transactions, Scotland has adopted a more targeted approach focused specifically on property development. Understanding these differences and the specific conditions attached to the Sub-Sale Development Relief (SSDR) is essential for anyone involved in development transactions in Scotland.

Understanding sub-sale transactions

A sub-sale occurs when an initial buyer contracts to purchase property from a seller but then, before completing that purchase, arranges to sell the property to a third party. In a typical scenario, party A agrees to sell land to party B. Before settlement, B contracts to sell the same land to party C. Without relief, this chain could trigger two separate Land and Buildings Transaction Tax (LBTT) charges, one on the transaction between A and B and another on the transaction between B and C.

Scotland initially left a gap in this area when LBTT was introduced in 2015, meaning both transactions would have been taxable. This was addressed by introducing SSDR under Schedule 10A of the Act, but with a significant difference. The Scottish relief is only available where the ultimate purchaser intends to carry out significant development on the property.

How Sub-Sale Development Relief works?

SSDR allows the first buyer in a sub-sale arrangement to claim relief from LBTT on their purchase from the original seller, provided the property is immediately sold on to a second buyer who intends to undertake significant development. The relief is only available to the intermediate buyer, not to any subsequent purchasers in a longer chain.

In practical terms, if A sells to B and B then sells to C, with C planning major development on the property, B can be relieved of LBTT on the transaction between A and B. Party C will still pay LBTT on their purchase from B as normal, but the intermediate tax charge on B is removed. This prevents double taxation while ensuring that the relief is tied to genuine development activity. By relieving that intermediate transaction, LBTT aligns with the commercial reality that the property effectively passes from A to C in one movement.

Qualifying conditions for relief

For B to claim SSDR, several conditions must be satisfied. First, there must be a qualifying sub-sale contract where B sells the whole or part of the property to C, and C becomes entitled to call for title. The transactions are usually coordinated so that completion or substantial performance of both the A to B transaction and the B to C transaction happens simultaneously and in connection with each other. This simultaneous completion links the deals together for relief purposes.

Second, and most importantly, C or another relevant party must intend to carry out significant development for commercial purposes on the property. Development is defined broadly to include substantial building or redevelopment of commercial, residential or industrial structures. This might involve constructing new offices, shops or housing. However, minor works or routine refurbishments will not qualify. The development must be significant relative to the nature and market value of the property. Simply refurbishing an existing building, without more, would typically not qualify if the work is minor in relation to the site's value.

Third, the significant development must be expected to be completed within five years from the effective date of the sub-sale to C. This five-year period ensures that relief is only given where genuine development activity follows within a reasonable timeframe. If development does not occur within that period, the relief may be withdrawn through clawback provisions.

Fourth, B's purchase from A must not itself be a sub-sale of some earlier contract. In other words, B must be the initial purchaser from A. The relief is designed for a straightforward sequence where B buys from A and simultaneously sells to C.

Where B only sub-sells part of the property to C while retaining some interest in the remainder, partial relief is available. In such cases, the LBTT charge on B's purchase is reduced on a just and reasonable apportionment basis, reflecting the portion of the property that was sold onwards. The remaining portion would still bear LBTT.

Claiming the relief and providing evidence

To benefit from SSDR, the first buyer must claim the relief in their LBTT return for the purchase from the original seller. This claim can be made either on the original return or by amending the return within the allowable amendment window. Revenue Scotland's guidance emphasises that the claimant should have evidence supporting the expectation of significant development. The evidence must demonstrate that at the effective date of the sub-sale, the intention for substantial development was genuine and plausible.

Withdrawal of relief and clawback

SSDR is subject to strict clawback provisions to ensure that the development actually occurs. If the significant development does not take place within the five-year period, the relief is withdrawn and the first buyer becomes liable for the LBTT that was originally relieved. In the example given earlier, if C fails to build the commercial complex and the land remains undeveloped or only minor works are done, then after five years B would owe the full LBTT on the £1 million purchase that had been relieved. Party B must file a further LBTT return and pay the tax due within 30 days after the five-year deadline expires.

There is also provision for partial withdrawal of relief. If some development occurs by the five-year mark but it falls short of what was considered significant, a portion of the relief can be revoked proportionately. The legislation calls for a just and reasonable apportionment in such cases. If only part of the planned construction was completed or the project was scaled down, Revenue Scotland can charge a fraction of the original LBTT to reflect the lesser degree of development achieved. The first buyer would need to make a return and pay the adjusted tax amount at the five-year point, with evidence of the partial development to support the apportionment.

Comparison with SDLT and LTT

The contrast with SDLT and LTT is instructive. Under SDLT, a general pre-completion transactions relief exists. If the first buyer transfers their rights to the ultimate buyer before completing the purchase from the original seller, the first buyer's acquisition can be ignored for SDLT purposes and only the ultimate buyer's acquisition is taxed. The SDLT rules require the transactions to be part of the same arrangement and completed in tandem, but they do not require any development by the ultimate buyer. SDLT prevents double tax on sub-sales generally, without a time bound development condition.

The Welsh LTT also provides relief for qualifying sub-sale arrangements that operates similarly to the SDLT regime. If the first buyer contracts to purchase then sub-sells to the ultimate buyer, and the transactions complete together, the first buyer can claim relief on their interim purchase. Wales did not impose a significant development requirement. LTT follows the general principle of relieving the intermediate transaction when the property is passed on to an ultimate buyer in one continuous process.

The contrast highlights Scotland's policy choice. By limiting relief to development scenarios, LBTT ensures that only those sub-sales contributing to economic development get preferential treatment. This targeted relief ensures that a developer in Scotland is not taxed twice on assembling a development site, but it also prevents the use of sub-sales purely as a tax planning device. Under LBTT, one cannot simply insert an intermediate entity to briefly take title and avoid tax unless there is bona fide development. In contrast, SDLT and LTT grant relief for many legitimate forward sale or property flip transactions, though with anti-avoidance provisions to police abuses.

Conclusion

Sub-Sale Development Relief in LBTT is a targeted provision aimed at encouraging property development in Scotland while protecting the tax base against avoidance. It allows an intermediate purchaser in a back-to-back deal to escape LBTT, but only when a substantial development by the ultimate buyer is planned and completed within five years. The relief's detailed conditions, including simultaneous completion of linked transactions, significant development requirements and strict clawback if development falters, reflect a carefully balanced approach to tax policy. When used appropriately, SSDR removes a potential tax obstacle from development deals, aligning LBTT treatment with the commercial reality that the property effectively passes from the original seller to the ultimate buyer in one movement.
