SDLT overlap relief: rent on a replacement lease
SDLT overlap relief
Where a qualifying old lease is replaced, the law can reduce the rent counted under the new lease for the period both leases would cover.
- The statutory conditions matter.
- The archived HMRC page gives no example facts.
- Lease documents and rent figures are central.

SDLT overlap relief: rent on a replacement lease
Stamp duty can count rent on a new lease. Overlap relief can reduce that rent when an old lease would otherwise cover the same period.
The supplied HMRC page is archived. It does not include its original Example 2.
What this rule is about
The aim is simple: SDLT should not count two lots of rent for the same premises and the same time when a tenant replaces an existing lease before its original end date.
That is the issue.
The legislation sets the relief, not the manual.
What the official source says
HMRC’s archived page says that SDLT stopped applying to land transactions in Scotland from April 2015, but it gives no further example text.
Finance Act 2003 sets out the overlap rule for qualifying replacement leases.
- You surrender an old lease and receive a new lease of the same, or nearly the same, premises.
- Or a protected business tenant requests and signs a new tenancy.
- Or a sub-tenant receives a replacement lease after the head lease ends in specified circumstances.
- Or a guarantor receives a replacement lease under the guarantee.
What this means in practice
For the overlap period, SDLT treats rent under the new lease as lower by the rent that would have been due under the old lease.
The reduction cannot make the new rent negative.
- Check whether both leases cover the same dates.
- Use the old rent amount used in the earlier SDLT calculation.
- Do not assume every lease renewal qualifies.
How to analyse it
Start with the documents. The label given to the deal does not decide the answer.
- Identify why the old lease ended.
- Check which statutory replacement situation applies.
- Compare the premises in both leases.
- Work out the dates and rent for the overlap period.
Example
Sam gives up an old lease with £1,000 monthly rent and receives a qualifying new lease for the same premises at £1,400 a month.
For a month when the leases overlap, the new lease rent counts as £400, not £1,400.
This illustrates the rent adjustment, not the final stamp duty bill.
Why this can be difficult in practice
The paperwork is often the hard part, because you must show that the replacement fits one of the listed situations and that the premises are the same or substantially the same.
A new lease alone is not enough.
- A new lease alone does not prove eligibility.
- Different premises may prevent the relief.
- The archived HMRC page cannot fill gaps in the lease documents.
Key takeaways
- Overlap relief can prevent double counting of rent.
- It applies only in listed replacement-lease situations.
- The supplied HMRC page contains no usable Example 2 facts.
Technical analysis

Legislation
- FA 2003 Schedule 17A para 9 — reducing rent where replacement lease periods overlap
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 supplied archived page gives no transaction facts, lease terms or calculation for Example 2, so it cannot establish how HMRC would apply the rule to a particular case.
- The relevant transaction date is needed before relying on the current consolidated statutory text.
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 old and new leases and their dates.
- Proof that the premises are the same or substantially the same.
- The old lease rent used for the earlier SDLT calculation.
- The new lease rent and the period when both rents would otherwise overlap.
