Guide on Stamp Duty Land Tax for Right to Buy and Shared Ownership Transactions

SDLT reliefs and rules for right to buy and shared ownership

This HMRC manual page is a contents page for the special SDLT rules in Schedule 9 to the Finance Act 2003 covering right to buy, shared ownership, staircasing, rent-to-buy style arrangements, and shared ownership trusts. It does not give the full legal rules, but it shows the main issues to check and where HMRC’s detailed guidance can be found.

• These rules apply to housing arrangements that do not follow a simple one-off purchase, such as shared ownership leases, right to buy, and shared ownership trusts.
• SDLT treatment can depend on the exact legal structure, including whether the buyer acquires only part of the property first and pays rent on the rest.
• A key issue is whether a market value election is available and made, as this can affect when SDLT is paid and how later purchases of extra shares are taxed.
• If no market value election is made, later staircasing transactions and the linked transaction rules may become important.
• The manual also points to guidance on chargeable consideration, rent-to-mortgage and rent-to-loan cases, shared ownership trusts, and SDLT1 return completion.
• You should not rely on this contents page alone to work out SDLT; the detailed legislation and the later HMRC manual pages must be checked.

SDLT reliefs for right to buy and shared ownership: what this part of HMRC’s manual covers

This part of HMRC’s SDLT manual is a contents page for the rules on right to buy, shared ownership leases, staircasing, rent-to-buy style arrangements, and shared ownership trusts. It does not itself set out the legal rules in detail. Its main value is that it shows the topics covered by Schedule 9 to Finance Act 2003 and how HMRC has organised its guidance.

What this rule is about

Schedule 9 to Finance Act 2003 contains special SDLT rules for certain housing transactions that do not fit neatly into an ordinary sale and purchase model. In particular, it deals with:

• right to buy transactions
• shared ownership leases
• market value elections for some shared ownership arrangements
• staircasing, where further shares in a property are acquired over time
• rent-to-mortgage, rent-to-loan, and rent-to-shared-ownership arrangements
• shared ownership trusts

These rules matter because SDLT can work differently where a buyer acquires only part of the value of a property at first, pays rent on the rest, or has a statutory or contractual route to acquire more later. The tax treatment may depend on the exact structure of the deal and on whether a market value election is made.

What the official source says

The source provided is an HMRC manual contents page headed SDLTM27000. It lists the following topics:

• a general overview of section 70 and Schedule 9 of Finance Act 2003
• the definition of right to buy
• guidance on SDLT treatment of right to buy transactions
• conditions a shared ownership lease must satisfy
• detailed conditions for a market value election where the freehold reversion is available
• how the freehold reversion is treated where that election is made
• detailed conditions for a market value election for leasehold property where additional shares may be bought
• treatment of staircasing where no market value election is made
• the effect of linked transaction rules where no market value election is made
• chargeable consideration in rent-to-mortgage or rent-to-loan cases
• treatment of rent-to-shared-ownership lease transactions
• introduction to shared ownership trusts
• general conditions for shared ownership trusts
• the meaning of “purchaser” in that context
• market value election rules for shared ownership trusts
• cases where no election is made for shared ownership trusts
• rent-to-shared-ownership trust transactions
• notes for completing the SDLT1 return

Because this is only a contents page, it points to the legal issues but does not explain them in substance. The detailed rules sit in the legislation and in the later manual pages listed here.

What this means in practice

If you are dealing with a right to buy or shared ownership transaction, you should not assume the normal SDLT approach for a straightforward freehold purchase applies without modification.

The contents page shows that the SDLT analysis is likely to turn on questions such as:

• Is the transaction a statutory right to buy case?
• Is the interest being acquired a shared ownership lease that meets the statutory conditions?
• Can the buyer acquire further shares later?
• Is there an option to pay SDLT by reference to market value up front?
• If no market value election is made, how are later staircasing transactions taxed?
• Do linked transaction rules affect the calculation?
• Is the arrangement a lease structure, a trust structure, or a rent-to-buy style arrangement?

In practice, these distinctions can change both when SDLT is paid and how much is paid over the life of the arrangement.

How to analyse it

A sensible way to approach a transaction covered by this part of the manual is:

1. Identify the legal structure. Is it right to buy, shared ownership lease, shared ownership trust, or a rent-to-buy variant?
2. Check the statutory conditions. The contents page shows that several separate pages are devoted just to the conditions that must be met.
3. Decide whether a market value election is available and, if so, whether it has been or will be made.
4. If no election is made, consider the later consequences, especially staircasing and linked transaction treatment.
5. Work out what counts as chargeable consideration. In some arrangements this may include more than a simple premium.
6. Check the filing position. The manual includes a page specifically on SDLT1 return completion, which suggests that return treatment may not be intuitive.

This framework matters because shared ownership and similar schemes often involve a sequence of transactions rather than a single purchase. SDLT may need to be considered at each stage.

Example

Illustration: a buyer acquires an initial share in a property under a shared ownership lease and pays rent on the landlord’s remaining share. The buyer may later staircase by buying further shares. The contents page shows that SDLT treatment may differ depending on whether a market value election is made at the outset. If an election is made, one set of rules applies. If no election is made, later staircasing and linked transaction rules may become important. To reach the right answer, you would need the detailed guidance in the later pages listed in SDLTM27000 and the wording of Schedule 9.

Why this can be difficult in practice

The difficulty is that people often describe very different schemes using similar language. “Shared ownership”, “rent to buy”, and “right to buy” are not interchangeable labels for SDLT purposes. The legal form matters.

A second difficulty is that the contents page itself does not tell you the operative rule. It only tells you where HMRC discusses it. That means you cannot safely rely on this page alone to determine SDLT treatment.

A third difficulty is timing. In shared ownership cases, SDLT may depend not only on the first grant or purchase, but also on later acquisitions of further shares and on whether transactions are treated as linked.

Key takeaways

• This HMRC page is only a contents page, but it shows the main SDLT issues for right to buy and shared ownership arrangements.
• The SDLT result may depend heavily on the precise structure of the arrangement and on whether a market value election is available or made.
• For any real transaction, the detailed Schedule 9 rules and the specific HMRC pages listed here need to be checked.
