Fixed-term leases and SDLT: working out the lease term
Fixed-term lease term for SDLT
For initial SDLT purposes, a lease has a fixed term when its length can be worked out when granted. HMRC says the lease and related documents may both matter.
- Use the contractual term, or the shorter period from grant to its end.
- Ignore break clauses and renewal rights initially.
- Check whether dates are stated as “from” or “from and including”.

Fixed-term leases and SDLT: working out the lease term
For stamp duty land tax, the lease term is not always the period you expect. SDLT first asks whether the parties could identify the length when they granted the lease. That answer can shape the initial tax calculation where, for example, the lease includes a break clause or renewal right that might later alter what happens. It matters.
What this rule is about
A fixed-term lease has an end point that people can work out at the start. It may end on a stated date. Or it may last for a stated number of years from its grant date.
The answer does not have to appear in the lease alone. An agreement for lease or a practical completion certificate may supply the missing date or detail.
Why does this matter? SDLT needs a term to work out the initial treatment of a lease. A short lease and a long lease can produce different results.
What the official source says
HMRC’s manual says a lease has a fixed term if people can work out its term when they grant it. The wording of the lease, read with any relevant linked document, must make that possible.
- A lease ending on a named date can be a fixed-term lease.
- A lease lasting for a set period from its grant can also be a fixed-term lease.
- The starting point is the contractual term written into the lease.
- If the parties grant the lease after that term has begun, use the shorter period running from grant until its contractual end.
- Ignore a clause that could end the lease early.
- Ignore either side’s right to end the lease.
- Ignore either side’s right to renew it.
That last point is set by Finance Act 2003 Schedule 17A paragraph 2. It applies when working out the initial SDLT position for a fixed-term lease.
What this means in practice
Break clauses do not shorten the term. Do not extend it because the tenant may later renew either. For the initial SDLT calculation, use the fixed contractual period.
This can feel odd. The tenant may be very likely to use a break clause. But the law tells you to leave it out at this stage.
- Read the term clause before looking at the break clause.
- Check whether the stated end date is certain.
- Check whether another signed document fixes the start or end date.
- Use the actual grant date if it leaves less time than the written contractual term.
- Keep the break and renewal clauses on file, even though you ignore them initially.
If the lease later ends or renews, that may have separate SDLT effects. This HMRC page does not set out those effects in detail.
How to analyse it
Start with the documents, not the label on the lease. Calling a lease “fixed term” does not settle the issue if the documents do not show how long it will last.
- Find the date on which the lease was granted.
- Find the exact words setting its start and end.
- Read any agreement for lease and completion certificate.
- Ask whether those documents made the end point clear on the grant date.
- Work out the written contractual period.
- Compare it with the period from grant to the contractual end.
- Use the shorter period if the lease was granted after its stated term began.
- Leave out break clauses and renewal rights for the initial calculation.
One wording point matters more than it seems: “from” a date normally leaves that date out. “From and including” a date includes it.
Example
Suppose a lease says it lasts for 10 years from 25 March 2006. HMRC’s manual treats that wording as starting on 26 March 2006 and ending on 25 March 2016.
Now change four words. If it says “10 years from and including 25 March 2006”, it starts on 25 March 2006 and ends on 24 March 2016. The period is still 10 years, but the calendar dates differ.
Add a tenant break option after five years. For the initial SDLT calculation, that option is ignored. The lease is still treated by reference to its fixed 10-year term.
Why this can be difficult in practice
The difficult part is often not the arithmetic. It is deciding what the documents actually say. Lease drafting can use several dates, and a completion date may sit outside the lease itself.
You might think the date printed at the top of the lease is always the start date. It is not. The grant date, the stated commencement date and the date possession begins can all need checking.
- An agreement for lease may make the term clear where the lease does not.
- A practical completion certificate may decide when a stated period starts.
- “From” and “from and including” lead to different calendar results.
- A likely break is still ignored for the initial fixed-term calculation.
- A renewal granted after a tenant has stayed on may need separate treatment.
- If the statutory conditions apply, a backdated renewal lease can start on its expressed start date.
For certain backdated renewal leases granted on or after 19 July 2006, HMRC’s manual changes the normal position where the tenant stayed after the old lease ended and then received a new lease of the same or substantially the same premises, expressed to start on or just after that end date. Finance Act 2003 Schedule 17A paragraph 9A contains the conditions.
Broadly, the tenant must have stayed after the old lease ended and then receive a new lease of the same or substantially the same premises, expressed to start on or just after that end date.
Key takeaways
- A fixed term must be clear when the lease is granted.
- Related documents can help show the term.
- Ignore breaks and renewal rights for the initial SDLT calculation.
- Check date wording with care.
- Later termination or renewal may need separate SDLT analysis.

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 source does not give a complete method for resolving unclear or conflicting wording across the lease and related documents.
- Whether a document makes the term clear at the grant date can depend on the precise facts and drafting.
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 every version of its term clause
- The date the lease was granted
- Any agreement for lease or practical completion certificate
- The stated start and end dates
- Any break clause, renewal right or holding-over arrangement
