SDLT repayment after a failed contract
You may be able to reclaim SDLT where tax was paid after a contract had substantially taken effect, but the contract later fell through.
- Taking possession or making a substantial payment can be decisive.

SDLT refund when a property contract falls through
If you paid stamp duty because a property contract had already taken effect, but the deal later fell through, you may be able to get some or all of the SDLT back. The key is not simply whether the sale completed. It is whether the contract had been substantially performed first.
What this rule is about
SDLT usually comes up when a property purchase completes. Sometimes, substantial performance makes a contract a land transaction before completion.
Where you take possession of the property or make nearly all of the payment, and the contract then ends without being carried out, the law allows repayment of SDLT paid on that earlier event. That timing point matters.
A deal falling through before this stage is different.
What the official source says
HMRC’s manual says you can recover SDLT when the parties rescind or annul a contract, or otherwise do not carry it into effect, wholly or partly. The legislation applies this to tax paid where the parties had substantially performed the contract before completion and later rescinded, annulled, or did not carry it into effect. That sequence matters.
- The parties must have substantially performed the contract before completion.
- You may have taken possession of all or most of the property.
- Instead, you may have paid or provided all or most of the amount due.
- The parties must later end, cancel, or not carry out the contract.
- If only part fails, repayment covers only that part.
- You claim repayment by amending the SDLT return for the contract.
There is a similar rule where the parties substantially performed an agreement for a lease but later did not go ahead.
What this means in practice
You may still claim a refund even if you correctly paid SDLT at the time, provided the contract was substantially performed and later ended without being carried into effect. That later outcome can alter the result.
Do not assume that every cancelled purchase creates a refund. For this refund route to apply, the earlier SDLT charge must have arisen because the contract was substantially performed before the parties ended, cancelled, or failed to carry it out. A failed purchase alone is not enough.
- Keep the original contract and SDLT return.
- Keep evidence of payments made under the contract.
- Record when someone gave you access or possession.
- Keep the document that ended, cancelled or changed the deal.
- Check whether the whole contract failed or only part of it.
How to analyse it
Start with the sequence of events. Dates and documents matter more than the label used for the deal.
- Was there a contract for a land transaction?
- Did completion take place?
- Before completion, did you take possession of the property?
- Before completion, did you pay all or substantially all of the price?
- Did the parties later rescind, annul or fail to carry out the contract?
- How much SDLT did you pay because of that contract?
- Can you still amend within 12 months of the filing date?
A negative answer may end that route. The source page does not set out another route.
Example
Amira agrees to buy a shop. The parties allow her into it before the final transfer. She pays £8,000 of SDLT because substantial performance brings the contract into effect. The parties later cancel the contract and the transfer never happens. Met conditions let her amend the return. They also permit repayment of the £8,000.
Change one fact and the answer may differ. If Amira never took possession and did not make a substantial payment before cancellation, this particular rule may not be engaged.
Why this can be difficult in practice
This is the part people get wrong: a failed deal alone is not enough. First identify why SDLT was paid. Then trace what happened afterward.
- Early access may or may not amount to possession.
- A deposit is not always a substantial payment.
- A later variation may differ from a true cancellation.
- Partly carrying out a contract can limit the repayment.
- The 12-month amendment deadline runs from the filing date, not from cancellation.
Key takeaways
- A substantially performed contract can trigger SDLT before completion.
- If it later falls through, SDLT may be repayable.
- Use an amendment to the original return within the time limit.
Technical analysis

Legislation
- FA 2003 section 44 — when a substantially performed contract counts as a transaction; when a contract has been substantially performed; repayment where a contract is later not carried out
- FA 2003 Schedule 17A para 12A — when an agreement for lease is treated as a lease; repayment where an agreement for lease falls through
- FA 2003 Schedule 10 para 6 — how and when a buyer may amend a return
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
- Whether a contract was substantially performed can depend on exactly what possession was given and what payments were made.
- The supplied legislation is current only to 17 November 2025. Transactions after that date need a check against current primary legislation.
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 contract and any later agreement ending or changing it.
- Evidence of the date and extent of any possession.
- Evidence of all payments made under the contract.
- The original SDLT return, filing date and proof of SDLT paid.
- Documents showing which part of the contract was not carried out.
