Stamp duty where a backdated lease follows holding over
Backdated leases after holding over
When a tenant stays after a lease ends and later signs a backdated replacement lease, SDLT may treat the new term as starting on its stated date.
- The special rule needs continued occupation and the same or substantially the same premises.
- Rent in the gap can reduce the new lease rent where it was already taxable for SDLT.
- Check both lease dates, plans and rent records.

Stamp duty where a backdated lease follows holding over
Your lease may end while you remain in the property, and a later lease may state that it started back at the old end date, although the parties grant it later. That matters. Stamp duty may treat that stated date as the new lease’s start. This can affect the rent used for SDLT. Everything turns on whether the special rule for a tenant who has held over applies.
What this rule is about
Holding over means remaining after lease expiry. It often happens while a landlord and tenant agree the terms of a replacement lease.
The parties may later sign a backdated lease. It may state that it began on the day the old lease ended.
Without a special SDLT rule, a landlord, tenant or adviser could struggle to work out the term and rent for the gap after the old lease ended but before the parties granted the new document. That gap matters.
SDLT on a lease can take account of rent over its term. Counting rent for the same period twice could produce the wrong result.
What the official source says
HMRC’s manual says the special rule applies to a qualifying backdated lease granted on or after 19 July 2006. The legislation is Finance Act 2003 Schedule 17A paragraph 9A. HMRC’s manual is guidance, not the law itself.
That provision determines the SDLT start date. For SDLT, the new lease begins on the date written in it.
The provision still has that effect even if the parties granted the lease document later.
- The tenant must remain in occupation after the old lease’s contractual end date.
- The tenant must then receive a new lease.
- The new lease must cover the same or substantially the same premises.
- The new lease must specify a term starting on the old contractual end date or immediately after that date.
- HMRC’s explanation covers SDLT lease grants. Former stamp duty is outside that explanation.
- For the holding-over period, taxable rent payable otherwise than under that new lease may reduce the rent under the new lease.
- The reduction cannot take the rent counted under the new lease below nil.
What this means in practice
The replacement lease’s stated start date matters. It is not merely background wording. Where the special rule applies, SDLT uses that date as the start of the new term.
The rules also protect against counting rent twice. Rent paid during the gap may reduce the rent counted under the new lease for SDLT, but only where SDLT already took that earlier rent into account. Otherwise, it cannot.
What actually decides this? Start with the documents, not the label “renewal”. A lease described as a renewal can fail the test. This may happen if it covers materially different premises or starts too late.
- Keep the old and new leases together with any plans.
- Check the exact contractual end date of the old lease.
- Check whether the tenant stayed in occupation after that date.
- Compare the areas covered by both leases.
- Identify when the parties granted the new lease.
- Read the clause which states when its term begins.
- Match rent demands and payments to the holding-over period.
How to analyse it
Work through the facts in order. Do not assume that every lease signed after holding over receives the special treatment.
- Find the old lease’s contractual termination date.
- Establish whether the tenant stayed in occupation after that date.
- Identify when the parties granted the new lease.
- Compare the premises in both leases and their plans.
- Check the stated commencement date in the new lease.
- Decide whether it is on, or immediately after, the old end date.
- Record rent paid or due from the old end date until the parties grant the new lease.
- Check whether any of that rent was taxable rent for SDLT purposes.
- Apply any reduction only up to the amount of rent counted under the new lease.
Example
Sian’s lease of a shop ends. She remains in the shop while the parties agree terms for a replacement lease.
The parties grant the replacement lease later. It covers the same shop and says its term began immediately after the old lease ended.
On those facts, the special rule can apply. SDLT uses the stated date, not the grant date.
If SDLT already treated rent for the gap as taxable rent, that amount can reduce the rent counted under the new lease for the same gap. It cannot create a negative rent figure.
Why this can be difficult in practice
People often go wrong here because they must distinguish the date the old lease ended from the separate date on which the parties granted the new lease. Two dates matter. The new lease must also state the right start date.
Small property changes can matter as well. A new lease of a larger unit, a different floor, or only part of the old site may raise a real question about whether the premises are substantially the same.
- Do not assume that staying after expiry is enough by itself.
- Do not assume that a lease described as a renewal covers the same premises.
- Do not treat every payment during the gap as a rent reduction for SDLT.
- Check whether the gap payment was actually taken into account for SDLT.
- A rent increase agreed through a lease variation may raise a separate SDLT issue.
Key takeaways
- A qualifying backdated lease starts for SDLT on its stated start date.
- The same tenant and the same or substantially the same premises are essential facts.
- Rent in the holding-over gap may be relieved from double counting, but only within the statutory limits.
Technical analysis
For advisers, and for anyone who wants to check the law behind this page. You do not need this section to understand the guidance above.
Legislation
- FA 2003 Schedule 17A para 9A — backdated leases granted after a tenant holds over
- FA 2003 Schedule 17A para 13 — rent increases treated as new lease grants
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 premises are the same or substantially the same can depend on the plans and the area actually occupied.
- Whether rent during the holding-over period was taken into account for SDLT can depend on the old lease, payments and earlier SDLT treatment.
- The supplied statutory text is current only to 17 November 2025. Current primary legislation should be checked for a transaction after that date.
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 lease and its contractual end date
- proof that the tenant remained in occupation
- the new lease, including its grant date and stated start date
- plans for both leases
- rent demands and payments during the holding-over period
- the SDLT treatment of the old lease and any earlier returns
