Understanding Rent to Shared Ownership Lease Schemes and Their Tax Implications

SDLT treatment of rent to shared ownership schemes

In some rent to shared ownership schemes, a person first rents a home under an assured shorthold tenancy and later takes a shared ownership lease of the same property. Where the arrangement falls within paragraph 13 of Schedule 9 to the Finance Act 2003, SDLT treats the tenancy and later lease separately: they are not linked transactions, and the tenant’s earlier occupation is ignored when working out the effective date of the shared ownership lease.

• The rule only applies to a defined rent to shared ownership lease scheme involving a qualifying body and the same dwelling.
• It covers cases where the occupier may later get a shared ownership lease, including where they can apply subject to a financial assessment or already have a contractual right.
• If the scheme qualifies, the assured shorthold tenancy, the shared ownership lease, and related scheme transactions such as an option are treated as not linked for SDLT purposes.
• Occupation under the assured shorthold tenancy does not bring forward the effective date of the later shared ownership lease for SDLT.
• This means the lease is normally treated as taking effect when it is granted, even if the occupier was already living there as a tenant.
• The main practical issue is checking whether the arrangement genuinely falls within the statutory scheme, rather than assuming any tenancy followed by shared ownership will qualify.

SDLT and rent to shared ownership schemes: when earlier tenancy arrangements are ignored

This page explains a specific SDLT rule for rent to shared ownership schemes. The rule matters because a person may first occupy a home as a tenant and only later take a shared ownership lease. Without a special rule, those steps might be treated as linked transactions or might affect the timing of the SDLT charge. The legislation prevents that in certain cases.

What this rule is about

Some affordable housing schemes are structured in stages. A qualifying body first grants an assured shorthold tenancy of a dwelling. Later, the occupier may move into shared ownership by taking a shared ownership lease of the same property.

The SDLT question is how those steps should be treated. In particular:

• Should the tenancy and later shared ownership lease be treated as linked transactions?
• Does the occupier’s earlier possession under the tenancy bring forward the effective date of the shared ownership lease?

Paragraph 13 of Schedule 9 to Finance Act 2003 deals with this. It applies only to a “rent to shared ownership lease scheme” as defined by that provision.

What the official source says

The official material says that the rule applies where:

• a qualifying body may grant a shared ownership lease of a dwelling to a person or persons, and
• that body also grants those person or persons an assured shorthold tenancy of the dwelling.

For this purpose, “assured shorthold tenancy” has the meaning given by Part 1 of the Housing Act 1988.

The phrase “may be granted” is wider than a simple unconditional right. It includes cases where:

• the scheme allows the person to apply for a shared ownership lease, but only after an assessment of their financial circumstances, or
• the person already has a contractual or other right to be granted the lease, for example because there is a contract in place that has not yet completed.

Where the arrangement falls within the statutory definition, 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 manual says this includes:

• the grant of the assured shorthold tenancy,
• the grant of the shared ownership lease, and
• other land transactions entered into as part of the scheme, such as an option.

The source also says that possession of the dwelling under the assured shorthold tenancy is ignored when deciding the effective date of the grant of the shared ownership lease under section 44 FA 2003. So if the occupier takes possession as a tenant after exchange of contracts but before the shared ownership lease is actually granted, that earlier possession does not make the lease effective for SDLT purposes before the date of grant.

The manual adds an important point: if the person was already occupying the property under the assured shorthold tenancy when contracts for the shared ownership lease were exchanged, substantial performance is not triggered anyway. The source cross-refers to HMRC guidance on that point.

What this means in practice

If the arrangement is a qualifying rent to shared ownership lease scheme, SDLT should analyse the tenancy stage and the later shared ownership stage separately, rather than aggregating them as linked transactions under the normal linking rules.

That can matter because linked transaction treatment can affect how SDLT is calculated. This provision prevents the earlier tenancy from being folded into the later shared ownership transaction simply because both steps form part of the same scheme.

The rule on effective date is also important. In SDLT, the effective date often determines when the return and tax position are assessed. Normally, early possession can sometimes amount to substantial performance and bring the effective date forward. But this provision says that possession under the assured shorthold tenancy is disregarded when working out the effective date of the later shared ownership lease.

In practical terms, that means the later lease is still treated as taking effect when it is granted, even if the occupier has already moved in as a tenant under the scheme.

How to analyse it

A sensible way to approach the issue is to ask these questions in order:

• Is there a dwelling?
• Is there a qualifying body granting the arrangements?
• Has the body granted an assured shorthold tenancy of that dwelling?
• Does the scheme provide that the occupier may be granted a shared ownership lease of the same dwelling?
• Is that possibility broad enough to fall within the statutory wording, including a right to apply subject to financial assessment, or an existing contractual or other right to the lease?
• Are the transactions in question between the qualifying body and the occupier or occupiers under that scheme?

If the answer to those points is yes, the legislation treats the scheme transactions as not linked for section 108 purposes.

You should then separately consider timing:

• Was the occupier in possession under the assured shorthold tenancy before the shared ownership lease was granted?
• If so, that possession is ignored when deciding the effective date of the grant of the shared ownership lease under section 44.

The key practical point is to identify the legal capacity in which the person is occupying the dwelling. Occupation as tenant under the assured shorthold tenancy is not treated in the same way as possession under the shared ownership purchase arrangements.

Example

A housing association runs a scheme under which Ms A first takes an assured shorthold tenancy of a flat. The scheme says that after a period of renting she may apply for a shared ownership lease, subject to a review of her financial circumstances. She moves into the flat as a tenant. Later, contracts are exchanged for the shared ownership lease, and the lease is formally granted after that.

On the HMRC view reflected in this material:

• the tenancy and the later shared ownership lease are treated as not linked transactions if the scheme falls within paragraph 13, and
• Ms A’s occupation under the tenancy is ignored when deciding the effective date of the grant of the shared ownership lease.

So the lease is not treated as having an earlier effective date merely because she was already living in the property as a tenant under the scheme.

Why this can be difficult in practice

The main difficulty is usually not the effect of the rule, but whether the arrangement actually falls within it.

In particular:

• The scheme must be one under which a qualifying body grants both the tenancy and the route into shared ownership.
• The statutory wording “may be granted” is wide, but it still requires a real scheme structure connecting the tenancy and the possible shared ownership lease.
• It may not always be obvious whether a separate agreement, option, or contractual right forms part of the same scheme.
• The source explains HMRC’s treatment, but the legal starting point remains paragraph 13 of Schedule 9 FA 2003 and the related SDLT provisions on linked transactions and effective date.

Another practical issue is that readers sometimes assume any tenancy followed by any later shared ownership purchase will be covered. That is too broad. The protection applies to a defined type of scheme, not to every case where renting happens before shared ownership.

Key takeaways

• In a qualifying rent to shared ownership lease scheme, the tenancy, shared ownership lease, and related scheme transactions are treated as not linked for SDLT purposes.
• Occupation under the assured shorthold tenancy is ignored when deciding the effective date of the later shared ownership lease.
• The critical question is whether the arrangement truly falls within paragraph 13 of Schedule 9 FA 2003, including the requirement for a qualifying body and a scheme giving access to a shared ownership lease.
