Right to buy and shared ownership stamp duty: HMRC’s guide
In short
HMRC’s page is a map to its guidance on SDLT for right to buy and shared ownership arrangements. The legal answer depends on the detailed scheme documents and the statutory rules in Schedule 9.
- Check the type of scheme and housing provider.
- Check whether a market value election was made.
- Review every later share purchase separately.

Right to buy and shared ownership stamp duty: HMRC’s guide
If you are buying your home through right to buy or shared ownership, stamp duty can depend on the scheme documents and choices made at the start. HMRC’s page is not an answer sheet. It is a contents page that points to guidance on several different arrangements.
What this rule is about
Shared ownership is not always one simple property purchase. You may first buy a share, pay rent on the rest, and later buy more shares. Right to buy sales can also include a discount or a later payment.
Schedule 9 to the Finance Act 2003 has special SDLT rules for these situations. It explains tax at each stage.
What matters most is the legal route you are using. A shared ownership lease, a shared ownership trust and rent-to-buy arrangements have separate rules.
What the official source says
HMRC’s manual page lists the detailed topics in its right to buy and shared ownership section. It covers the following main areas:
- what HMRC calls a right to buy transaction
- discounted sales or leases by listed public bodies
- shared ownership leases that allow a buyer to obtain the freehold
- shared ownership leases that let a buyer purchase extra shares
- the choice to use the full market value at the start
- buying further shares, often called staircasing
- rent to mortgage and rent to loan arrangements
- shared ownership trusts
- rent to shared ownership lease or trust schemes
- notes for completing an SDLT return
The manual is HMRC guidance, not the law. The legal rules sit in Schedule 9. Right-to-buy rules cover later-contingent payments.
For a qualifying shared ownership lease, the buyer may choose market value treatment in the SDLT return. That choice is permanent. If it applies, the starting tax calculation uses the value stated in the lease and ignores the rent.
What this means in practice
The key decision may come before you complete. A market value choice can change when SDLT is considered on later share purchases. Check lease and future share-buying plans first.
- Check whether the landlord is a qualifying body under the legislation.
- Check whether the lease gives you exclusive use of the home.
- Read whether the lease gives you a right to buy the freehold.
- Read whether it lets you reduce rent by buying more shares.
- Find the market value and minimum-rent statements in the lease.
- Keep a copy of the SDLT return and any election.
Without a market value choice, the initial payment and rent can be treated differently. Later staircasing may be exempt while your total share immediately after the purchase does not exceed 80%.
That is a limit in the legislation, not a general rule that every later payment is tax-free.
How to analyse it
Start with the paperwork, not the scheme’s marketing name. Two schemes described as shared ownership can have different legal terms.
- Identify whether this is right to buy, a shared ownership lease or a trust.
- Confirm that the provider meets the statutory definition.
- Identify the initial payment, rent and any discount.
- Check whether the contract states a market value or minimum rent.
- Check whether a valid market value election was made.
- List each later payment for an extra share.
- Work out the total percentage owned after each payment.
- Check whether the scheme began with an assured shorthold tenancy.
Where a tenant moves from an assured shorthold tenancy into a qualifying shared ownership scheme, the legislation separates the tenancy, the later lease or trust, and other steps in the scheme. Tenancy possession is ignored for later leases or trusts.
Example
Priya has a qualifying shared ownership lease and initially owns a 25% share. She later pays for another share, taking her total to 50%. If no market value election was made, the later purchase may be exempt because her total share immediately afterwards does not exceed 80%.
Change one fact and the answer may change. Above 80%, Schedule 9’s automatic exemption ends. Calculate any SDLT under that date’s rules.
Why this can be difficult in practice
People often assume SDLT looks only at the first share price. That can miss the point. The lease wording, the election and each later transaction can all matter.
- A housing provider may not meet the qualifying-body test.
- The lease may not contain the statements the market value route requires.
- An election cannot later be withdrawn because the buyer’s plans change.
- The 80% test looks at the share held immediately after the later purchase.
- A rent-to-shared-ownership arrangement has special rules of its own.
- HMRC’s contents page does not replace reading the relevant detailed guidance or legislation.
If your solicitor has said SDLT is due, ask which transaction is being taxed: the first lease, a later share purchase, or the transfer of the remaining interest. That simple question often makes the issue clearer.
Key takeaways
- HMRC’s page is an index to guidance, not a personal tax decision.
- Shared ownership SDLT depends on the documents and any election made.
- Later share purchases need checking separately, especially near the 80% point.

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
- This contents page does not give enough facts to determine the SDLT due on any individual purchase.
- The correct treatment after 17 November 2025 should be checked against the current legislation and the transaction date.
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 signed lease or shared ownership trust deed
- the housing provider’s identity and status
- the stated market value and initial share
- the SDLT return and any market value election
- details and dates of each later share purchase
- evidence that any SDLT due on the first transaction was paid
