No SDLT on some contracts made before 10 July 2003
Although completion took place in 2005, no stamp duty land tax was due for the historic purchase in HMRC’s example because the contract date controlled, subject to the transitional conditions and exceptions. Completion alone did not decide it.
What this rule is about
For land deals, SDLT replaced the old stamp duty system, but transitional rules prevented the new tax from automatically applying to every earlier contract that completed later. It was a historic rule.
It does not create an exemption for a new property purchase.
What the official source says
HMRC gives an example of a contract made on 1 January 2003 and completed on 1 January 2005. HMRC says that transaction was not subject to SDLT.
- The contract was made before 10 July 2003.
- It was not substantially performed before completion.
- No exception to the transitional protection applied.
- The transfer went to the buyer named in the contract.
What this means in practice
For an old transaction, do not treat a completion date after SDLT began as conclusive, because both the contract and everything that followed it can matter. Check both.
- A later change to the contract can remove the protection.
- Giving contract rights to someone else can remove it.
- Using an option or pre-emption right can also matter.
How to analyse it
Work through the paperwork in date order. This is the part people can miss.
- Find the date the original contract was made.
- Check who was entitled to receive the transfer.
- Check for later changes, assignments, sub-sales or options.
- Check whether possession or almost all payment happened early.
Example
Jane signed a contract on 1 January 2003. She did not move in or make the relevant early payment before completion. Nothing changed in the contract, and the property transferred to Jane on 1 January 2005. On HMRC’s stated example, this was not an SDLT transaction.
Why this can be difficult in practice
Because old files may not clearly show every later agreement, a side letter, a change of buyer, or early access to the property may affect the answer. Details matter.
- Calling a document a “variation” is not enough by itself.
- Early occupation can be important.
- The full chain of documents needs checking.
Key takeaways
- This rule concerns historic contracts.
- The original contract date matters greatly.
- Later changes can alter the SDLT result.

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 later dealings amount to a change to the contract or an assignment can depend on the documents and facts.
- The date of the contract, completion and any possession or payments must be established from evidence.
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 transfer or conveyance showing completion
- Any later changes, assignments, options or sub-sales
- Evidence of possession and payments before completion
