What counts as a lease for stamp duty land tax?
SDLT lease definition
For SDLT, a lease can include a fixed-term lease, a periodic tenancy and some rights that can end on notice. The main question is whether the end of the term can be worked out when the arrangement begins.
- A periodic tenancy is normally indefinite.
- A tenancy at will is exempt for SDLT.
- An agreement for lease can matter if it is substantially performed.

What counts as a lease for stamp duty land tax?
For SDLT, a lease can cover not only a long, formal tenancy but also a right over land for any length of time, including a periodic arrangement.
Getting the label right matters.
SDLT treats fixed and open-ended leases differently.
What this rule is about
When you take premises to rent, paperwork may use many labels, but SDLT looks to the arrangement’s reality when deciding whether you hold a lease rather than mere permission to use a space.
Labels do not decide.
For this purpose, a lease can last less than a year, run from year to year, or cover part of a year, and its short length does not place it outside the definition.
Short does not mean excluded.
What decides the lease type? Ask whether the parties could know its end when it started.
What the official source says
HMRC’s manual says SDLT uses a wide definition of a lease, covering an interest or right over land for a fixed term or a periodic term.
Either side may end another right by notice.
- A fixed term has a known duration.
- The answer may appear in the lease itself or in a supporting document.
- A lease ending on a stated date is a fixed-term lease.
- A lease lasting for a stated number of years from its start is also fixed-term.
- A periodic tenancy has no known end date when it begins, so it is an indefinite-term lease.
- It counts, but SDLT exempts it.
The legislation tells readers to work out a fixed term without allowing for an early break right or a right to renew, even where either right could affect how long occupation continues.
An early option does not automatically open the term.
What this means in practice
The fixed or indefinite label is not just filing language, because it affects how SDLT deals with both the lease length and the rent.
Initially, SDLT treats it as fixed.
That fixed lease lasts one year.
It then covers longer periods if it continues.
A tenancy at will needs special care. It may meet the SDLT definition of a lease, yet it is an exempt interest. That means it does not create an SDLT charge merely because it is a tenancy at will.
- Read the full documents, not only the heading on the first page.
- Check whether another document fixes the start date or end date.
- Do not assume a monthly payment means a fixed one-month lease.
- Do not assume a short right to occupy is a licence.
- Keep records of when possession began and when payments started.
How to analyse it
Work through the arrangement in order. Names used by the landlord and tenant can help, but they do not settle the SDLT position.
- Identify the land or premises covered by the arrangement.
- Ask whether the document gives a right over that land for a period.
- Find the start date and the stated end date, if there is one.
- Check any agreement for lease, completion certificate or side letter.
- Decide whether the parties could know the term when they granted the lease.
- If there is no knowable end, consider whether it is periodic or otherwise indefinite.
- Check whether it is truly a tenancy at will.
- Consider separately whether the arrangement is instead a licence.
Although signing an agreement for lease does not normally make SDLT treat it as the lease itself, SDLT may treat it differently when the parties substantially perform it before formal lease completion.
Timing matters.
Substantial performance has a specific SDLT meaning, and it can happen when the buyer takes possession of all, or almost all, of the property, or when a substantial amount is paid.
Where rent is the only payment, the first rent payment can be enough.
Example
Ravi signs an agreement for a three-year shop lease, and after building work finishes the formal lease will be signed, while a certificate of practical completion fixes its start date and the lease then runs for three years.
The term is knowable at the outset.
It is a fixed-term lease.
Now change one detail. Ravi moves in under a monthly arrangement that continues until either side gives notice, so nobody knows its end date when it begins.
SDLT calls this an indefinite-term lease.
Both sides may expect it to last only a few months.
Why this can be difficult in practice
This is the part people often miss: the answer may sit outside the main lease. A side letter, building certificate or agreement for lease may be needed to work out the term.
The line between a tenancy at will, a periodic tenancy and a licence can also be fact-sensitive, because calling an arrangement a tenancy at will does not end the enquiry and its terms and the way the parties act still matter.
The facts still matter.
- A lease may start before the final document is signed.
- Possession before completion can affect the SDLT analysis.
- The first rent payment may matter where an agreement for lease is in place.
- A break clause does not necessarily make a fixed term indefinite.
- For transactions after 17 November 2025, check the current legislation before relying on this page.
Key takeaways
- A lease can be very short or periodic.
- The known end date is the main dividing line.
- An agreement for lease may matter before the formal lease is signed.

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 an agreement has been substantially performed depends on what has happened, including possession and payments.
- The legal materials supplied are current only to 17 November 2025. Current 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 signed lease and any agreement for lease
- Any certificate or document that fixes the start or end date
- Evidence of possession, rent payments and other payments
- Correspondence showing whether the arrangement was intended as a lease or licence
