Stamp duty on a lease agreed before SDLT began
For a lease that crossed the 2003 changeover, the agreement and the signed lease could fall under different taxes. HMRC’s example treats the agreement under old stamp duty and the signed lease under stamp duty land tax.
What this rule is about
Stamp duty land tax, usually called SDLT or stamp duty, replaced the older stamp duty system for land deals. During the changeover, parties might make an agreement for a lease before SDLT started and sign the lease itself later.
Why did two taxes matter? The agreement and the final lease were separate documents, with the changeover falling between their dates.
What the official source says
Where parties made an agreement for a lease on 1 August 2003 before SDLT started, and executed the lease on 31 January 2004 after the changeover, HMRC uses the arrangement as its example. The two dates differ.
- The agreement did not create an SDLT transaction when it was made.
- HMRC says the old stamp duty rules applied to that agreement.
- The signed lease later created an SDLT transaction.
- HMRC says the signed lease was not also subject to old stamp duty.
Finance Act 2003 includes a transition rule for credit. Where someone paid value-based stamp duty on a contract before the changeover, that payment can reduce the SDLT due. That credit cannot produce a repayment.
What this means in practice
The credit prevents the same value-based amount from being taxed twice without allowance. It does not mean the earlier agreement disappears. Its date and any duty paid still matter.
- Check when the agreement was made.
- Check when the final lease was executed.
- Keep evidence of stamp duty paid on the agreement.
- Match the final lease against the earlier agreement.
How to analyse it
Start with the timeline. The key question is not simply when the lease began, but when each document was made and what each document did.
- Identify the date of the agreement for lease.
- Identify the date the lease was executed.
- Ask whether the lease gave effect to that agreement.
- Work out whether old stamp duty was paid on the agreement.
- Apply any available credit against SDLT on the lease.
Example
HMRC’s example uses no tax figures. On 1 August 2003, the parties make an agreement, and old stamp duty applies to it. On 31 January 2004, the parties execute the lease. According to HMRC, SDLT covers that lease, with credit for any value-based stamp duty paid on the earlier agreement.
Why this can be difficult in practice
Dates matter, but the documents matter too. A lease only gives effect to an agreement under the transition rule if it matches the agreement or covers substantially the same property and term.
- A later lease may differ from the earlier agreement.
- Records may not show whether old stamp duty was paid.
- The word “completed” can hide important document dates.
- HMRC’s example does not decide every unusual lease arrangement.
Key takeaways
- Historic lease agreements can sit under the old stamp duty rules.
- A later signed lease could instead fall within SDLT.
- Earlier value-based stamp duty may reduce SDLT, but cannot create a repayment.

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.
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 date the agreement for lease was entered into
- the date the lease was executed
- the agreement and executed lease
- evidence of any value-based stamp duty paid on the agreement
