Shared Ownership Leases: Market Value Election Conditions for Freehold Reversion

SDLT market value election for shared ownership leases with a right to buy the freehold

A buyer of certain shared ownership leases can choose to pay SDLT upfront on the property’s full market value instead of paying SDLT in stages. This only applies where the lease meets strict legal conditions, including giving the tenant a route to acquire the freehold later, and the election must be made correctly in the SDLT return because it cannot be undone.

• The lease must provide for the tenant to acquire the freehold reversion, and it must be granted partly for rent and partly for a premium.
• The premium must be worked out by reference to the dwelling’s market value, or to a sum derived from that market value, and the lease must state that figure.
• For this rule, market value is based on vacant possession, not the usual SDLT market value definition.
• The election is made in the SDLT return for the grant of the lease by entering the market value as the consideration.
• If the original return did not make the election, it may be possible to amend it within 12 months of the filing date, but after that the opportunity may be lost.
• Because the election is irrevocable, advisers should check the lease wording, valuation basis and SDLT filing carefully before submitting the return.

SDLT on shared ownership leases where the freehold can later be bought: market value election

This page explains when a buyer of a shared ownership lease can choose to pay SDLT upfront on the full market value of the property, rather than paying SDLT in stages. It deals specifically with shared ownership arrangements where the lease gives the tenant a route to acquire the freehold reversion later. The conditions are technical, but they matter because a valid market value election changes how SDLT is charged and the choice cannot later be undone.

What this rule is about

Shared ownership leases are taxed under special SDLT rules. In some cases, the buyer can elect to pay SDLT by reference to the market value of the dwelling at the start, instead of paying SDLT only on the initial premium and then potentially on later staircasing transactions.

The material here concerns one particular type of shared ownership lease: a lease under which the freehold reversion is available to the tenant. In broad terms, that means the structure of the lease allows the tenant to acquire the landlord’s freehold interest.

This is not just about whether the property is described as “shared ownership”. The lease must satisfy specific statutory conditions before the market value election is available.

What the official source says

HMRC says that, in addition to the general conditions for this type of relief, the lease must meet all of the following requirements.

• The lease must provide for the tenant, or joint tenants, to acquire the freehold reversion.
• The lease must be granted partly for rent and partly for a premium.
• That premium must be calculated by reference to the market value of the dwelling, or by reference to a sum itself calculated by reference to the market value of the dwelling.
• The lease must contain a statement of that market value, or of the relevant sum calculated by reference to market value, because that is the figure by reference to which the premium is worked out.
• The tenant must make an election for SDLT to be charged under Schedule 9 paragraph 2 of Finance Act 2003 on that stated market value, or on that stated sum calculated by reference to market value.

The source also highlights an important technical point. For this purpose, the usual SDLT definition of “market value” in section 118 FA 2003 does not apply. Instead, the market value is worked out on a vacant possession basis.

HMRC states that the election is made in the SDLT return for the grant of the lease by entering the market value as the consideration. If the original return did not do that, the return can be amended to make the election, but only within 12 months of the filing date.

Once made, the election is irrevocable. It cannot later be withdrawn or altered by a further amendment.

What this means in practice

The practical question is whether the buyer can choose the “market value election” route at all. If the lease meets the statutory conditions and the election is properly made, SDLT is charged by reference to the market value figure stated in the lease, or the relevant stated sum derived from market value.

This matters because the SDLT treatment of shared ownership can otherwise operate differently over time. An upfront market value election may simplify the SDLT position, but it also fixes the tax treatment at the outset. Because the election is irreversible, the return needs to be completed with care.

The lease wording is central. It is not enough that the parties informally intended shared ownership or intended that the tenant might eventually buy more of the property. The lease itself must:

• provide for acquisition of the freehold reversion, and
• show that the premium is calculated by reference to market value, and
• contain the required statement of the relevant market value or linked sum.

If those ingredients are missing from the lease, the ability to make a valid market value election may be in doubt.

The vacant possession point is also important. The figure used is not simply whatever value might apply for every other SDLT purpose. For this election, the legislation requires a vacant possession approach. That can affect the amount entered on the return.

How to analyse it

A sensible way to analyse the position is to work through the documents and the filing steps in order.

• First, confirm that the arrangement is a shared ownership lease falling within the relevant SDLT framework, including the general conditions referred to in HMRC’s related guidance.
• Second, check whether the lease actually provides for the tenant to acquire the freehold reversion. This should be clear from the lease terms.
• Third, identify the consideration on grant. The rule requires a combination of rent and premium.
• Fourth, test how the premium is calculated. It must be calculated by reference to the market value of the dwelling, or to a sum derived from that market value.
• Fifth, check the lease for an express statement of the relevant market value or relevant sum. If the lease does not state it, that is a warning sign.
• Sixth, consider the correct vacant possession market value for this purpose, because the normal section 118 definition is disapplied.
• Seventh, check the SDLT return. To make the election, the market value must be shown as the consideration. If that was not done on the original filing, consider whether an amendment is still possible within 12 months of the filing date.
• Finally, remember that once the election is made, it cannot be reversed.

For conveyancers and advisers, this means the SDLT analysis cannot be separated from the drafting of the lease and the valuation basis used in the transaction documents.

Example

This is an illustration only.

A housing association grants a shared ownership lease of a house. The lease requires the tenant to pay an initial premium and ongoing rent. The premium is worked out by reference to the stated market value of the house, and the lease expressly states that value. The lease also provides a route for the tenant to acquire the freehold reversion.

If the tenant wants SDLT to be charged on the market value basis under these rules, the tenant must make that election through the SDLT return for the grant of the lease by showing the market value as the consideration. If the return is filed on a different basis, the tenant may still be able to amend it, but only within 12 months of the filing date. After a valid election is made, it cannot be withdrawn.

Why this can be difficult in practice

The main difficulty is that eligibility depends heavily on the detailed terms of the lease. A transaction may be described commercially as shared ownership, but that does not answer the statutory questions.

There can also be uncertainty if:

• the lease does not clearly provide for acquisition of the freehold reversion,
• the premium formula is not expressly tied to market value,
• the lease omits the required statement of market value or the relevant sum, or
• the figure used in the return does not reflect the vacant possession basis required by the legislation.

Timing is another practical risk. If the original SDLT return did not make the election, the amendment window is limited. Missing that deadline may leave the buyer stuck with the original SDLT treatment.

Finally, HMRC’s manual explains how HMRC reads the legislation, but the legal effect ultimately depends on the statute. Where the documents are unusual or incomplete, the answer may be fact-sensitive.

Key takeaways

• A market value election for a shared ownership lease is only available if the lease meets specific statutory conditions, including provision for the tenant to acquire the freehold reversion.
• The lease must link the premium to market value and must state the relevant market value or related sum in the lease itself.
• The election is made through the SDLT return, can only be added by amendment within 12 months of the filing date, and once made it cannot be revoked.
