Stamp duty on right to buy and shared ownership homes
Shared ownership stamp duty: the short answer
Schedule 9 can change how SDLT applies to right to buy and qualifying shared ownership schemes. The most important decision is often whether to make a market value election at the start.
- The election is irrevocable.
- It can exempt later staircasing and the final transfer.
- Without it, the 80% total-share test is crucial.

Stamp duty on right to buy and shared ownership homes
Stamp duty land tax, often called stamp duty, has special rules for right to buy and qualifying shared ownership schemes.
Depending on the route you choose, tax may be based on the whole home at the start or on shares as you buy them. That choice can affect later staircasing payments.
What this rule is about
Shared ownership usually involves buying a percentage of your home while paying rent on the rest. You may later buy more shares. This is called staircasing.
Under ordinary SDLT rules, connected property deals can be treated together. They can also take account of a payment that may become due later. Schedule 9 changes those results for certain housing schemes.
This is not a general relief for every discounted home or every shared ownership product. What matters is the scheme and the organisation providing it.
What the official source says
Schedule 9 has a defined scope. According to HMRC’s manual, it covers right to buy, shared ownership and related arrangements, although that manual records HMRC’s view while Finance Act 2003 contains the legal rules. The Act is controlling.
- For a qualifying right to buy sale or lease, a later payment that depends on an uncertain event is left out.
- This stops the amount used for SDLT exceeding the discounted price paid for the home.
- A qualifying shared ownership lease can use a market value election.
- That election treats the whole stated value as the amount paid at the outset.
- The election is irrevocable and belongs in the SDLT return, or a valid amendment to it.
- Where that election was made and any SDLT due on the lease was paid, later staircasing and the final transfer are exempt.
- Without an election, a staircasing purchase is exempt if the buyer’s total share immediately after it is no more than 80%.
- The first shared ownership lease is treated as separate from qualifying later staircasing and the final transfer.
Equivalent rules also apply to a shared ownership trust. This is a trust-based arrangement for a home, rather than the usual lease structure.
What this means in practice
When your shared ownership lease or trust starts, you must decide whether to pay SDLT by reference to the whole stated value, which can remove SDLT from later share purchases but may increase tax due at the start. Choose at the outset.
The alternative considers the parts you buy separately. It can leave later purchases outside SDLT while your total share stays at or below 80%. A purchase taking you above that point may need a separate SDLT check.
- Check whether the landlord or provider is a qualifying body under Schedule 9.
- Check that the home gives you exclusive use and meets the other lease conditions.
- Read the lease for its stated value, premium and rent terms.
- Keep the SDLT return and any amendment safely.
- Before staircasing, check your existing percentage and the percentage you will hold afterwards.
- Do not assume the final transfer is tax-free unless the statutory conditions are met.
In rent-to-shared-ownership schemes, where you first occupy under an assured shorthold tenancy before entering the later shared ownership arrangement, the statute treats the tenancy and that later arrangement as not linked and ignores possession under it when fixing the effective date of the later lease or trust declaration. Earlier possession is ignored.
How to analyse it
Begin with the paperwork rather than the scheme’s marketing name. A product described as shared ownership may still need to meet the detailed statutory conditions.
- Is this a right to buy sale, a shared ownership lease, a shared ownership trust, or a rent-to-shared-ownership scheme?
- Who granted the arrangement, and do they count as a qualifying body?
- Does the lease or trust contain the required terms and stated value?
- Was a market value election made in the SDLT return or an amendment?
- If there was no election, what percentage do you own immediately after each staircasing payment?
- Are you buying the final interest under the original terms of the lease or trust?
- Did an earlier tenancy form part of a qualifying rent-to-shared-ownership scheme?
Separate rules apply. For a rent to mortgage scheme, SDLT uses the price that would apply under the statutory right-to-buy calculation, whereas for the Scottish rent to loan scheme it uses the corresponding Scottish statutory price.
Example
Amir takes a qualifying shared ownership lease over a £250,000 home. He buys an initial 25% share for £62,500 and does not make a market value election.
Later, he buys a further 55%. He then owns 80%, so that staircasing purchase is exempt under Schedule 9.
When he later buys another 5%, taking his share to 85%, the 80% exemption no longer applies, so the SDLT result for that later purchase must be worked out under the rules in force then. Later rules govern that purchase.
Why this can be difficult in practice
People often miss the 80% point. It is not a lifetime allowance. The law asks what share you hold immediately after that particular purchase.
Calling an arrangement “shared ownership” might seem to settle the issue. It does not. Provider, lease wording, rent terms and the election all matter.
- A market value election cannot be withdrawn because later plans change.
- A private registered provider has extra funding conditions before it counts as a qualifying body in some cases.
- A tenancy before the shared ownership deal matters only if it is part of the statutory rent-to-shared-ownership scheme.
- The stated whole-property value must appear in the relevant lease or trust terms.
- The rules for a lease and a trust are similar, but they are not identical.
- Current SDLT rates are not set by this overview and depend on the transaction date.
Key takeaways
- Schedule 9 gives special SDLT treatment to defined housing schemes.
- The market value election is a one-way choice made through the SDLT return.
- Without that election, staircasing is generally exempt only up to a total 80% share.

Official guidance
The pages below are HMRC’s guidance. Guidance is not law. It sets out how HMRC reads the legislation, and it is not binding on you, on a tribunal or on a court. Where guidance and the legislation differ, the legislation wins. HMRC can also change or withdraw guidance, and it may not cover your facts.
Where this is not settled
- The right answer depends on the exact scheme documents, the body granting the lease or trust arrangement, and whether a valid election was made.
- The supplied legislation is consolidated only to 17 November 2025. A transaction on a later date needs current-law checking before this guidance is applied.
Evidence you would need
This kind of case is decided on the facts of the individual property. These are the records that usually settle it, and the ones an adviser would ask you for.
- The lease, trust deed, tenancy agreement and any staircasing documents.
- The identity and status of the housing body or social landlord.
- The stated whole-property value, initial payment, rent and minimum rent in the documents.
- The SDLT return and any amendment showing whether an election was made.
- Dates of the tenancy, shared ownership grant, later share purchases and final transfer.
