Open-ended leases and SDLT
A periodic or other open-ended lease is treated as a one-year lease first. If it continues, SDLT treats it as a longer fixed lease each year.
- Continuation can create extra SDLT
- A later return may be needed

Stamp duty when an open-ended lease continues
An open-ended lease can create a fresh stamp duty issue each year it continues. For SDLT, the law treats it as a one-year fixed lease at first, then as a longer lease if it carries on.
What this rule is about
Some leases have no set end date, including periodic tenancies, tenancies at will, and leases ended by notice. All three can fall within this group.
This sounds like a paperwork point. It can affect SDLT, a later return, and the amount due.
What the official source says
Although the HMRC page supplied here is a contents page, it links to HMRC pages about the treatment of these leases and an example, while Schedule 17A to the Finance Act 2003 sets out the detailed legal rule. Use both sources.
- At first, the law treats an indefinite lease as a fixed lease of one year.
- If it continues, the law treats it as a fixed lease of two years.
- Each further continuation adds one year.
- Ignore other laws’ assumed lease terms.
What this means in practice
Staying put can affect SDLT. Nobody needs to sign again.
Even when nobody signs a new document, staying in the property can matter because each anniversary can require you to check the SDLT position again. Anniversaries matter.
- A later year can make the lease notifiable for SDLT purposes.
- A later year can produce tax where none was due before.
- It can also create extra tax on an earlier SDLT position.
How to analyse it
Start with the lease, not its everyday label. What matters is whether it has a fixed end date and whether it has continued.
- Check whether the lease is periodic or can end on notice.
- Find the date it began and each anniversary after that.
- Check whether the tenant stayed beyond each assumed one-year term.
- Work out whether that continuation changes SDLT or return requirements.
Example
Maya takes a monthly periodic lease on 1 May. SDLT first treats it as a one-year lease. If Maya remains after 30 April the next year, SDLT treats her lease as lasting two years, and you must check the SDLT position using the rules that applied on the lease’s effective date. Maya then has a two-year lease.
Why this can be difficult in practice
People often look only at the original agreement. That can miss the fact that the lease continued. The dates, rent, and any later lease all matter.
- Calling an arrangement a rolling tenancy does not settle the SDLT answer.
- The filing reason sets a later return’s deadline.
- An indefinite lease counts as under seven years for SDLT notification rules.
Key takeaways
- For SDLT, an open-ended lease grows one year at a time.
- Continuation can change the SDLT result.
- Keep the lease, dates, and rent records together.

- FA 2003 Schedule 17A para 4 — treats an indefinite lease as yearly fixed terms; disregards other statutory term deeming rules; sets deadline where continuation makes lease notifiable; sets deadline for tax caused by continuation; uses effective-date rates for later tax; requires assessment and payment with later return; applies return administration rules to later returns; treats indefinite leases as under seven years; defines leases for an indefinite period
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 source does not give the lease terms, rent, payments, or dates needed to decide whether tax or a later return is due in any real case.
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 lease and any later variation or replacement lease.
- The start date, notice terms, and date the lease actually ended, if it has ended.
- Rent records and details of any premium or other payment.
- Copies of earlier SDLT returns and calculations.
