Stamp Duty Land Tax (“SDLT”) liability can be a significant factor for developers to consider when considering purchasing land with an associated construction contract. The challenge arises in determining what consideration should be taken into account when calculating the SDLT liability. The question to be addressed is whether SDLT is due on the value of the land or on the cost of the land and the subsequent development.
Development agreements themselves are not land transactions for the purposes of SDLT and on their own would not give rise to a SDLT liability. However, if the consideration for a land transaction consists of, or includes construction obligations, it is possible that the value of the works could be chargeable consideration and therefore included in the calculation for SDLT greatly increasing the amount due.
These issues were considered in the case of Prudential Assurance Company Limited v Inland Revenue Commissions (1992) (“Prudential”).
The rule set out in Prudential means that:
- where a purchaser of land buys the site for one consideration and enters into a building contract under which the seller agrees to carry out the construction works for the purchaser for another consideration,
- the price paid under the building contract is not taken to be account for the sale unless the transactions are so intertwined that, in reality, the purchaser is buying the land with a completed building on it.
- Scope of the works: What works are to be carried out? Is design to be included as well as build? The scope will also include the type of construction to be performed, specification of the products, access and logistics of the site. These provisions are the heart of the contract and will assist us in advising what form of construction contract is appropriate for your transaction.
- Contract price: This is the consideration payable for the works. The developer must consider whether they are willing to take a flat fee or if this will be subject to a formula based on costs incurred. Consideration should also be given as to whether payments will be made in tranches and what obligations must be satisfied to trigger a payment.
- Variations: Construction projects change throughout and unanticipated difficulties crop up. Understanding how to value variations, agree and implement changes to the project and the associated cost of those changes is critical.
- Timings: When are the works to be completed? Are the works to be completed in phases and will completion dates be set for each phase? Consideration also needs to be given to the different trades involved and how they fit into the structure of the project.
- Payment regimes/schedules: What payment regime will apply? Who will certify payments? Will a retention mechanism operate?
- Obligations & responsibilities: Who will take on the responsibility for the necessary insurance policies and what level of insurance is required? Who is responsible for site condition risk, trespass etc.
- Funding: What funding arrangements are in place? What are the requirements of any lender, and will this affect the structure of the transaction or timings and payment schedules?
