SDLT rules for rent to shared ownership trust schemes

Special SDLT rules apply to certain social housing arrangements where a person first rents a home under an assured shorthold tenancy and may later become a beneficiary under a shared ownership trust. These rules are designed to stop the tenancy and later trust steps being treated as linked transactions or causing SDLT to arise earlier than intended.

• A qualifying scheme involves a social landlord granting an assured shorthold tenancy to a person who may later become a beneficiary under a shared ownership trust.
• For SDLT purposes, transactions between the landlord and the occupier under the scheme, including the tenancy, trust declaration and related steps such as an option, are treated as not linked.
• The occupier’s possession of the property under the tenancy is ignored when deciding the effective date of the later shared ownership trust declaration.
• This means early occupation under the tenancy does not by itself bring forward the SDLT timing for the trust transaction.
• The rule can still apply where the person only has a right to apply for shared ownership, subject to a financial assessment, or already has a contractual right that has not yet completed.
• In practice, it is important to check that the documents and facts show the arrangement genuinely falls within a rent to shared ownership trust scheme.

SDLT treatment of rent to shared ownership trust schemes

This page explains how SDLT works for certain social housing arrangements known as rent to shared ownership trust schemes. The rule matters because these schemes can involve several connected steps, such as a tenancy first and shared ownership later. Without a special rule, those steps might be treated as linked transactions or trigger SDLT earlier than expected.

What this rule is about

A rent to shared ownership trust scheme is a scheme involving a qualifying body, described here as the social landlord, and a person who may later become a beneficiary under a shared ownership trust. In the meantime, the person is granted an assured shorthold tenancy of the dwelling.

The legislation is dealing with a practical problem. These schemes often unfold in stages:

• the person first rents the property under an assured shorthold tenancy;
• later, the shared ownership trust is put in place; and
• there may also be other land transactions as part of the same scheme, such as an option.

Ordinarily, SDLT rules on linked transactions and effective date can make staged arrangements difficult. The special rule in Schedule 9 is intended to stop the tenancy and later trust steps being treated in a way that distorts the SDLT position.

What the official source says

HMRC says that Finance Act 2003 Schedule 9 paragraph 14 applies to rent to shared ownership trust schemes in a similar way to the rules for rent to shared ownership lease schemes.

According to the source, a rent to shared ownership trust scheme exists where:

• a person or persons may become a beneficiary, referred to as the purchaser, under a shared ownership trust with a qualifying body; and
• that qualifying body grants the person or persons an assured shorthold tenancy of the dwelling.

The source makes clear that “may be granted” is broad. It covers cases where:

• the scheme allows the person to apply to become a beneficiary, subject to a financial assessment; or
• the person already has a contractual or other right to become a beneficiary, even if the contract has not yet been completed.

The source then states two main SDLT consequences.

• Transactions between the qualifying body and the person or persons under the scheme are treated as not linked for the purposes of section 108 FA 2003.
• The person’s occupation under the assured shorthold tenancy is ignored when deciding the effective date of the declaration of the shared ownership trust under section 44 FA 2003.

HMRC says this non-linking treatment includes:

• the grant of the assured shorthold tenancy;
• the declaration of the shared ownership trust; and
• any other land transaction entered into as part of the scheme, for example an option.

On effective date, HMRC says that if the person takes possession under the assured shorthold tenancy after contracts are exchanged but before the trust is declared, that occupation does not make the trust transaction effective earlier. The effective date remains the date the trust is declared.

The manual also notes that substantial performance is not triggered in any event if the person was already occupying the property under the assured shorthold tenancy when contracts were exchanged.

What this means in practice

The practical effect is that the tenancy stage is separated from the later shared ownership trust stage for SDLT purposes.

That matters in two ways.

• First, the different steps in the scheme are not automatically aggregated as linked transactions under section 108 just because they are part of the same overall arrangement.
• Second, the tenant’s possession of the property under the assured shorthold tenancy does not, by itself, bring forward the SDLT timing for the declaration of the shared ownership trust.

For taxpayers and conveyancers, this means you should not assume that early occupation under the tenancy counts as possession for the later trust transaction. The legislation specifically tells you to disregard that possession when working out the effective date of the declaration of the trust.

It also means that where the scheme includes an assured shorthold tenancy, a trust declaration, and perhaps an option or similar step, those transactions are to be treated as not linked if they are transactions between the qualifying body and the person or persons under the scheme.

How to analyse it

A sensible way to analyse the arrangement is to work through these questions.

• Is there a qualifying body acting as the social landlord?
• Has the person been granted an assured shorthold tenancy of the dwelling?
• Under the scheme, may that person become a beneficiary under a shared ownership trust?
• Is that possibility only a right to apply, subject to financial assessment, or is there already a contractual right? Either can still fall within the rule.
• What land transactions exist between the qualifying body and the person or persons as part of the scheme? For example, the tenancy, the trust declaration, or an option.
• Are you considering whether those transactions are linked under section 108? If so, the source says they are treated as not linked.
• Are you considering whether occupation under the tenancy triggered an earlier effective date for the trust transaction under section 44? If so, that occupation must be disregarded.

The key point is to identify the legal character of each step. A person may be in occupation of the property, but that occupation may be attributable only to the assured shorthold tenancy, not to the later trust arrangement. The source says that distinction matters for SDLT timing.

Example

Illustration: a housing association grants Ms A an assured shorthold tenancy of a flat under a scheme that may later allow her to become a beneficiary under a shared ownership trust if she passes a financial assessment. Contracts for the trust arrangement are exchanged, and Ms A is already living in the flat under the tenancy. The trust is formally declared later.

On the basis of the HMRC material, Ms A’s occupation under the tenancy is ignored when deciding the effective date of the trust declaration. The effective date remains the date the trust is declared. The tenancy and the trust declaration are also treated as not linked transactions for section 108 purposes, provided they are transactions under the scheme between the qualifying body and Ms A.

Why this can be difficult in practice

The main difficulty is identifying whether the arrangement really falls within a rent to shared ownership trust scheme as described by the legislation and HMRC.

In some cases, the person only has a right to apply and must pass a financial assessment. In others, there is already a contractual or other right to become a beneficiary, but completion has not yet happened. The source indicates that both situations can still be covered, but the facts and documents need to support that conclusion.

Another practical issue is separating possession under the tenancy from possession that might otherwise amount to substantial performance of a later land transaction. The source gives a specific rule for disregarding possession under the assured shorthold tenancy when determining the effective date of the trust declaration. But that depends on the occupation truly being referable to the tenancy within the scheme.

There can also be care needed around the boundaries of the scheme. HMRC says the non-linking treatment includes other land transactions entered into as part of the scheme, such as an option. In practice, that raises a factual question: is the transaction genuinely part of the same rent to shared ownership trust scheme, or is it something separate?

Key takeaways

• In a qualifying rent to shared ownership trust scheme, the tenancy, trust declaration, and other scheme transactions are treated as not linked for SDLT section 108 purposes.
• Occupation under the assured shorthold tenancy is ignored when deciding the effective date of the declaration of the shared ownership trust.
• The rule can apply even where the person only has a right to apply, subject to financial assessment, or already has a contractual right that has not yet completed.
