Stamp duty when an agreement for a lease starts early
Stamp duty can arise before you sign your final lease when the parties have acted on an agreement for a lease in a major way and that action amounts to substantial performance. The tax date may then arrive earlier.
What this rule is about
Parties often sign an agreement for a lease before they execute the formal lease. Usually, signing it alone does not trigger SDLT. The position changes if the parties substantially perform the agreement before the landlord grants the lease.
In simple terms, the arrangement has moved from a plan to reality.
What the official source says
HMRC has archived the supplied page. It explains that, from April 2015, LBTT replaced SDLT for Scottish land transactions. HMRC manuals are guidance, not law.
For England and Northern Ireland, the legislation says:
- there must be an agreement for a lease
- it must be substantially performed before completion
- the agreement then counts as a lease
- that treated lease starts on the substantial-performance date
What this means in practice
Do not assume the tax date is the date you sign the final lease. Taking possession can trigger the rule. So can a payment that meets the statutory test.
- Check when you first occupied the premises.
- Check when rent or another major payment was made.
- Keep the agreement and payment records together.
How to analyse it
Start with the facts, not the label on the document.
- Is there an agreement for a lease?
- Was the final lease granted later?
- Did you take all, or nearly all, possession first?
- Did a payment make the agreement substantially performed?
Example
Amir signs an agreement for a shop lease. He moves in before the landlord grants the formal lease and pays the first rent. If his entry and first-rent payment amount to substantial performance, the law treats the agreement as a lease from that earlier date rather than the date when the parties sign the formal lease. That later signature does not simply reset the position.
Why this can be difficult in practice
Possession is not limited to having keys. A right to receive rental income can also count. Whether rent is the only amount paid or the arrangement includes other sums changes the payment test.
- Early access may be more than a casual licence.
- A payment may be rent, a premium, or something else.
- The final lease may change the overall tax result.
Key takeaways
- Acting on a lease agreement can trigger SDLT early.
- The facts fix the important date.
- Scotland has used LBTT, not SDLT, since April 2015.

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 someone has taken possession, or whether a payment triggers substantial performance, depends on the agreement and the facts.
- The supplied HMRC page does not explain how its former Scottish discussion applied to any particular transaction.
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 agreement for lease
- The date possession or a right to income began
- Records of rent and other payments
- The final lease and its commencement date
- The location and date of the land transaction
