Alternative Property Finance Reliefs: Overview and Definitions for Stamp Duty Land Tax

SDLT Relief for Alternative Property Finance Arrangements

SDLT relief can apply where property is bought through certain alternative finance arrangements instead of a normal mortgage, so that tax is not charged more than once just because the legal structure is different. The relief only applies if the arrangement matches the rules in the legislation, and an SDLT return must still be filed with the relief claimed.

• The relief is meant to put qualifying alternative property finance in a similar SDLT position to a standard purchase funded by a conventional mortgage.
• Typical qualifying structures include a financial institution buying the property and granting a long lease with a later right to transfer the freehold or reversion, or buying the property and reselling it to the customer with a legal mortgage back.
• Not all Sharia-compliant or non-standard finance arrangements qualify; the legal documents must fit the exact statutory model.
• If the conditions are met, the customer should not be taxed both on the institution’s purchase and on the later transfer, lease, or resale to the customer.
• An SDLT return is still required, the relief must be actively claimed, and the return should show the agreed transaction price as the chargeable consideration.
• HMRC guidance is helpful, but the actual law and the precise transaction documents are what decide whether the relief applies.

SDLT relief for alternative property finance arrangements

This page explains the SDLT relief that can apply where a property is bought using certain alternative property finance structures instead of a conventional mortgage. The purpose of the relief is to prevent SDLT being charged more than once simply because the finance is structured differently.

What this rule is about

Some property finance arrangements involve a financial institution buying the property first, or holding part of the interest in it, before the individual customer ends up with the property. Without a special rule, that structure could create more than one land transaction for SDLT purposes and therefore more than one SDLT charge.

The relief is intended to put qualifying alternative property finance on a similar SDLT footing to an ordinary purchase funded by a standard mortgage. In broad terms, if the statutory conditions are met, the SDLT outcome should broadly match the tax that would have arisen had the buyer simply bought the property directly with conventional borrowing.

What the official source says

The HMRC manual says that relief from multiple SDLT charges is available for three types of alternative property finance scheme, with one of those types having two variants. The extract provided describes two broad structures.

The first is where a financial institution buys the property, or an undivided share in it, and the customer is granted a long lease with a right to have the reversion transferred later. The manual also notes that the property interest can be transferred to the customer in stages during the lease term, while preserving the right to have the reversion transferred at the end.

The second is where the financial institution buys the property and then resells it to the customer, with the customer granting the institution a legal mortgage.

The manual states that, where relief is claimed, an SDLT return must still be filed. The return should claim the relief and show the chargeable consideration as the price agreed between the parties to the transaction.

The source also points to statutory definitions. In particular, “financial institution” takes its meaning from section 73BA of Finance Act 2003. For land in England, “legal mortgage” has the meaning given by section 205(1)(xvi) of the Law of Property Act 1925. For land in Northern Ireland, the manual gives the corresponding meaning for a mortgage by conveyance, demise, sub-demise, or charge by way of legal mortgage.

What this means in practice

The key practical point is that not every Sharia-compliant or non-standard finance arrangement automatically gets SDLT relief. The arrangement must fit within the statutory model.

If it does, the SDLT position is adjusted so that the customer is not unfairly taxed on both:

• the institution’s acquisition of the property, and
• the later transfer, lease, or resale to the customer.

This matters because alternative finance structures often involve extra legal steps that do not exist in a normal mortgage transaction. SDLT normally follows legal land transactions, so without relief the form of the arrangement could produce a higher tax charge than the economic substance would suggest.

The manual also makes clear that relief is not automatic in an administrative sense. A return must still be completed, and the relief must be claimed. The consideration shown on the return is the agreed price for the transaction, not some reduced figure simply because relief is being sought.

How to analyse it

A sensible way to analyse a transaction is to ask the following questions.

• Is there a qualifying financial institution involved, as defined by the legislation?
• Which statutory alternative property finance model is being used: purchase and lease, staged transfer during a lease arrangement, or purchase and resale with a mortgage back?
• Does the legal documentation actually match that model, or is it only commercially similar?
• Who acquires the property first, and what land interests are created at each stage?
• Is there a long lease, an option or right to acquire the reversion, or an onward resale to the customer?
• Where the arrangement involves a mortgage, is it a legal mortgage within the relevant legal definition?
• Has the SDLT return been prepared on the correct basis, with the relief actively claimed and the agreed price shown as chargeable consideration?

These questions matter because SDLT reliefs usually depend on the precise legal form of the transaction. A transaction may look economically like qualifying alternative finance but still fail if the documents do not produce the required legal steps.

Example

Illustration: a bank that qualifies as a financial institution buys a property from the seller. Instead of the customer buying directly from the seller with a normal mortgage, the bank grants the customer a long lease and the customer makes regular payments. The arrangement also gives the customer the right to have the reversion transferred later.

Without special relief, SDLT issues could arise on more than one step because the bank acquires the property and the customer later acquires rights over it. The relief is intended to prevent those multiple charges, so that the SDLT result broadly aligns with what would have happened if the customer had bought the property outright using an ordinary mortgage.

Why this can be difficult in practice

The difficult part is usually not the policy aim. The aim is clear enough: avoid overtaxing qualifying alternative finance. The difficulty is whether the arrangement falls exactly within the statutory conditions.

Several points can be fact-sensitive:

• whether the institution is a “financial institution” for the statutory definition, rather than in a general commercial sense;
• whether the customer’s rights amount to the kind of long lease and later transfer right contemplated by the legislation;
• whether staged transfers of beneficial ownership are structured in a way that preserves the required final transfer right;
• whether an onward financing arrangement is truly a resale with a legal mortgage, rather than a different form of security or contractual arrangement.

Another practical difficulty is that the HMRC manual is only guidance. The legal effect comes from the legislation it refers to, especially Finance Act 2003 sections 71A, 73 and 73BA. The manual is helpful for understanding HMRC’s view, but the statutory wording and the actual transaction documents remain decisive.

Key takeaways

• These SDLT reliefs are designed to stop qualifying alternative property finance from suffering multiple SDLT charges.
• The arrangement must fit the statutory structure; commercial similarity on its own is not enough.
• An SDLT return is still required, and the relief must be claimed using the agreed transaction price as the chargeable consideration shown on the return.
