Who must file and pay stamp duty? The SDLT buyer rule
Who is responsible?
For SDLT, responsibility normally follows the person who receives the property, lease or right under the deal. This can be different from the person people assume is the buyer.
- A tenant is normally the buyer on a new lease.
- A landlord is normally the buyer when a lease is surrendered.
- An agent may prepare a return, but responsibility remains with the buyer.

Who must file and pay stamp duty? The SDLT buyer rule
For stamp duty land tax, the person who receives the property or right will usually be responsible for the SDLT return and tax. That seems straightforward when you buy a home. The position can become far less clear where a lease ends, is altered, or gives somebody a fresh right that changes what they hold. That is not always obvious.
What this rule is about
SDLT applies to a land transaction. In simple terms, this means that someone obtains an interest or right connected with land.
The central question is: who obtained it? Finance Act 2003 describes that person as the purchaser. This page uses buyer, because that is normally what they are.
Identifying the right person matters. The buyer must handle the return for a notifiable transaction. Any tax due must also be paid by the filing date.
What the official source says
HMRC’s manual says that, whatever the payment arrangements may be and depending on the kind of land transaction involved, the buyer must meet reporting duties and pay SDLT. Who paid money does not decide it.
- On a transfer or conveyance, the buyer is the person receiving the land.
- On an assignment, the buyer is the person taking over the existing interest.
- When a lease is granted, the tenant is the buyer.
- When a lease is surrendered, the landlord is the buyer.
- When someone receives an easement, servitude or profit right, that person is the buyer.
- When a right is enlarged by a variation, the person gaining the benefit is the buyer.
- The same approach applies where a covenant or condition is made or released for someone’s benefit.
- Where there is more than one buyer, each person is covered by the return declaration requirement.
This approach reflects the legislation. It regards the person acquiring the subject of the deal as the buyer. Specific rules also cover the creation, surrender and variation of interests.
What this means in practice
Rather than deciding who handles SDLT from the label on the paperwork alone, consider what the transaction actually gives to every person involved. Look at the substance.
A solicitor, accountant or other agent can prepare and send the return. This does not transfer the underlying responsibility from the buyer.
- Check the names of all people receiving the land, lease or right.
- Read the operative parts of the document, not just its title.
- Make sure the return identifies the right person or people as buyers.
- Check the facts before any declaration is made.
- Keep the documents and calculations used for the return.
This is the point people may overlook. A lease surrender is not a sale in the everyday sense. Yet, because the landlord gets the leasehold interest back, the landlord is normally the buyer for SDLT purposes.
How to analyse it
Begin with what changes hands. Then consider who benefits from that change.
- What document or event created the transaction?
- Is it a transfer, a new lease, an assignment, a surrender or a variation?
- What land interest, right or benefit has been obtained?
- Who becomes entitled to it after the deal?
- Are there joint buyers who must be included?
- Is the transaction one that must be reported to HMRC?
- Has the buyer checked the information before the declaration is made?
You may assume that the person paying the legal bill is the buyer. That assumption does not settle the issue. The statutory test asks who obtains the subject of the transaction.
Example
Amir has a 20-year lease of a shop. He agrees to give it up early. For SDLT purposes, once the surrender takes effect and the landlord receives the leasehold interest back from Amir, the landlord is the buyer despite Amir giving up the lease. That is the result.
Now alter the facts. If Amir assigns the remaining lease to Beth instead, Beth takes over the lease. Beth is the buyer for this purpose.
Why this can be difficult in practice
Everyday labels in property documents can fail to reveal the SDLT outcome when a variation gives one person a significant new benefit or a release has the same effect. Titles are not decisive.
Although HMRC’s manual says a buyer must sign the declaration when an agent completes the return, the legislation provides a special route for an authorised agent’s declaration in a specified form. The buyer remains responsible.
- A document title may not show who gains the relevant right.
- Several connected documents may need to be read together.
- Joint ownership can mean more than one person must make a declaration.
- An agent preparing the form does not make the facts their responsibility alone.
- The current form and declaration process may matter where a signature issue arises.
Key takeaways
- The SDLT buyer is normally the person who gets the property, lease, right or benefit.
- Lease surrenders and variations can make the answer less obvious.
- An agent can help with the return, but the buyer remains responsible.

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
- HMRC’s manual says that a buyer must sign the declaration even where an agent completes the return. The supplied statutory text instead contains a specific process for declarations involving an authorised agent and does not itself set out a general signature rule. The current prescribed return form and applicable regulations should be checked where this matters.
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 transfer, lease, deed of surrender, deed of variation or other transaction document.
- Details of every person who receives the property, lease, right or benefit.
- The SDLT return and any authority appointing the agent.
- Information used to prepare the return and work out the tax.
