Understanding SDLT Higher Rate Charge for Non-Natural Persons in Property Acquisitions

SDLT relief withdrawal for alternative finance arrangements

When a company or other non-natural person buys residential property using alternative finance, the 15% SDLT rules and any reliefs still have to be monitored for three years from the effective date. If the conditions for relief stop being met during that period, the relief can be withdrawn. The key test is based on the position of the relevant person who entered into the arrangement, not the financial institution.

• The normal three-year control period still applies even if the purchase uses alternative finance arrangements.
• Any withdrawal of relief is judged by looking at the relevant person, meaning the party to the arrangement other than the financial institution.
• Where relief depends on a property letting, trading, or redevelopment business, the relevant person must hold the relevant interest throughout the control period.
• The relevant interest can include more than final legal ownership, including interests acquired or transferred at different stages of the finance structure and interests derived from them.
• If relief is withdrawn, the relevant person must file any further SDLT return, even if the financial institution dealt with the original filing.

SDLT higher rates for certain non-natural persons: alternative finance arrangements and when relief can be withdrawn

This page explains how the 15% SDLT charge for certain corporate and other non-natural person purchases of residential property interacts with alternative finance arrangements. The key point is that relief may be withdrawn if conditions stop being met during a three-year control period. Where alternative finance is used, the rules are applied by looking at the position of the “relevant person”, not the financial institution.

What this rule is about

Some acquisitions of residential property by companies and other non-natural persons can fall within a higher SDLT charge, subject to reliefs. One common area is where the property is acquired for a qualifying property business, such as letting, trading in, or redeveloping properties.

Separate SDLT rules deal with alternative finance arrangements. These are structures intended to achieve a financing result without using a conventional loan in the usual way. Because a financial institution may be involved in acquiring or holding the property interest as part of the arrangement, the legislation has to identify whose position matters when deciding whether relief continues to apply.

The source material deals with what happens after the transaction has completed. Even if relief was available at the outset, it can later be withdrawn if the statutory conditions cease to be met within the relevant period.

What the official source says

The official material says that, where alternative finance arrangements are used, the same three-year control period applies as in cases where they are not used. That period begins on the effective date of the transaction.

During that control period, the same withdrawal rules apply. The position must be considered from the perspective of the “relevant person”. This means the person, other than the financial institution, who entered into the alternative finance arrangements.

That matters for questions such as:

• whether a change in circumstances was foreseen, and
• whether the change was beyond that person’s control.

Where the relief depends on the property being held for a business of letting, trading in, or redeveloping properties, the relevant interest must be held by the relevant person throughout the control period.

The source defines “relevant interest” broadly. It includes:

• the interest acquired under the second transaction in the alternative finance arrangement,
• an interest bought jointly by a financial institution and another person,
• an interest transferred to the relevant person when rights under the arrangement are exercised, and
• any chargeable interest derived from those interests.

The source also makes clear that if the conditions for withdrawal are met, the obligation to file a further SDLT return falls on the relevant person, not the financial institution. That remains so even if the financial institution filed the return for the first transaction.

What this means in practice

The practical effect is that using alternative finance does not avoid the normal post-completion monitoring period for this relief. Relief can still be clawed back if the statutory conditions break down within three years.

The important practical shift is that the analysis is centred on the relevant person. In many alternative finance structures, the financial institution may temporarily hold an interest or may have been involved in the original filing. But for withdrawal purposes, the law asks what happened to the relevant person’s position.

So if the relief was claimed because the property was to be used in a qualifying property business, you need to check whether the relevant person continued to hold the relevant interest throughout the full three-year period. If they did not, withdrawal may be triggered unless the legislation provides otherwise.

This also affects compliance. The person responsible for any later SDLT return is the relevant person. They cannot assume that the bank or other financial institution will deal with it simply because that institution was involved in the original transaction documentation or filing.

How to analyse it

A sensible way to approach these cases is to work through the following questions.

• Was the transaction one where the higher SDLT charge for certain non-natural persons was potentially in point, but relief was claimed?
• Was the acquisition structured using alternative finance arrangements?
• Who is the “relevant person” for these purposes? This will be the person other than the financial institution who entered into the arrangement.
• What is the effective date of the transaction? That date starts the three-year control period.
• What is the “relevant interest” in this structure? Do not assume it is only the final legal title. The definition can include interests acquired at different stages of the arrangement and interests derived from them.
• Did the relevant person hold that relevant interest throughout the control period where the relief depended on a property rental, trading, or redevelopment business?
• If circumstances changed, should those changes be judged by reference to what was foreseen by the relevant person and what was beyond that person’s control?
• If withdrawal conditions apply, has the relevant person filed the further SDLT return required?

This framework matters because alternative finance arrangements can split legal and beneficial interests across more than one step. If you only look at who held legal title at one point in time, you may miss the statutory definition the legislation actually uses.

Example

Illustration: A company enters into an alternative finance arrangement with a financial institution to acquire residential property for its property rental business. Relief from the higher charge is available at the outset. Two years later, the company ceases to hold the relevant interest in the property during the control period.

On the source material, the case is analysed by looking at the company as the relevant person, not the financial institution. The question is whether the company held the relevant interest throughout the three-year period. If it did not, the relief may be withdrawn. If a further SDLT return is required, it is the company that must make it.

Why this can be difficult in practice

Alternative finance arrangements often involve multiple transactions and layered interests. That can make it hard to identify exactly what counts as the relevant interest and whether the relevant person has held it continuously.

Another difficulty is that the source refers to issues such as whether a change of circumstances was foreseen and whether it was beyond the control of the relevant person. Those questions can be fact-sensitive. They may depend on the transaction documents, the commercial background, and what was expected at the time.

There can also be a practical compliance trap. The financial institution may have handled the original SDLT filing for the first transaction, but that does not transfer responsibility for a later return if relief is withdrawn. The relevant person needs systems in place to monitor the three-year period and any events that may affect relief.

Key takeaways

• Using alternative finance does not remove the normal three-year control period for possible withdrawal of relief.
• The withdrawal analysis is carried out from the perspective of the relevant person, not the financial institution.
• If withdrawal conditions arise, the relevant person must make the further SDLT return.
