When a 2003 property sale moved from stamp duty to SDLT
For this historic sale, stamp duty land tax applied instead of the old stamp duty. Here, the key facts were simple: the contract was signed on 1 August 2003 and completion took place on 31 January 2004.
What this rule is about
Through transitional rules, SDLT replaced stamp duty for land sales. A sale could be agreed before the new system was fully in use, complete only later, and therefore require the transitional rules to identify the applicable tax system. Date order was the point. It decided which tax system applied.
What the official source says
HMRC’s manual gives this example. It says the sale is an SDLT transaction, so the legal transfer document, often called a conveyance, is not charged to the old stamp duty.
- The contract was made on 1 August 2003.
- That was after 10 July 2003.
- The sale completed on 31 January 2004.
What this means in practice
For this type of historic point, looking only at the completion date is not enough. When the parties made the contract also matters.
- Keep the signed contract and its date.
- Keep proof of the completion date.
- Check whether the contract later changed hands or changed terms.
How to analyse it
Start with the timeline. After that, match it to the transitional rules instead of assuming that old stamp duty applied merely because the sale began in 2003.
- When did the parties enter the contract?
- Was that date after 10 July 2003?
- When did completion happen?
- Was there a later variation or assignment?
Example
Anna signs a contract to buy land on 1 August 2003. Her legal transfer completes on 31 January 2004. On the facts in HMRC’s example, SDLT applies to the sale. Accordingly, the transfer document does not also face old stamp duty.
Why this can be difficult in practice
A date on the transfer document might seem to settle everything. It does not. During a change in tax rules, the contract date can be just as important.
- A contract made before the key date may need different treatment.
- A later change to a contract can matter.
- The short HMRC example does not cover every possible timeline.
Key takeaways
- This is a historic 2003 transition example.
- Contract and completion dates both matter.
- HMRC says SDLT applied on these stated facts.

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 short extract does not explain how the answer would change if the contract had been varied, assigned, or substantially performed before completion.
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 its date
- the completion date
- the transfer document
- evidence of any later variation, assignment, or early performance
