Stamp duty when your lease rent is reduced
Rent reductions under a lease
A lease variation which reduces rent is treated as a land transaction for SDLT. That does not automatically mean tax is due.
- Check whether you gave anything for the lower rent.
- No payment or valuable benefit can make the transaction exempt.
- Review side agreements as well as the lease variation.

Stamp duty when your lease rent is reduced
When your landlord agrees to cut the rent under an existing lease, the change can still count as a land transaction for stamp duty land tax (SDLT).
A rent cut alone does not mean you must pay SDLT, but you need to check carefully for any payment or other valuable thing given in return.
What this rule is about
A lease change can improve your financial deal. You need no new lease document.
The law specifically addresses rent reductions; it does not treat every lease change as irrelevant.
What the official source says
The supplied HMRC page is only a contents page. It directs readers to a separate section on reducing rent, but gives no outcome itself.
The legislation treats a variation that reduces rent as the tenant acquiring an interest in land.
- The lease must be varied, not merely discussed.
- The variation must reduce the amount of rent.
- The law treats the change as a land transaction for the tenant.
- This can apply without a new lease document.
What this means in practice
First, establish whether there is a land transaction. Next, check what you gave for the lower rent, including any valuable benefit provided as part of the wider deal.
- No payment or valuable benefit means the transaction is exempt from SDLT.
- A cash payment may need a separate SDLT calculation.
- Keep the signed variation and related correspondence.
How to analyse it
Start with the signed variation and its effective date. Then assess the whole commercial deal.
Calling it a rent concession does not establish what was given for it.
- Check that the rent, rather than another term, has reduced.
- Identify every payment, benefit or promise linked to the change.
- Decide whether that value was given for the rent reduction.
- Check for an SDLT exemption before working out tax.
Example
Example: Asha’s landlord agrees to reduce annual rent from £24,000 to £18,000. Asha gives nothing for the change.
The change remains a land transaction. Because Asha gave no payment or other valuable benefit, the exemption applies.
If she pays £10,000 for the lower rent, that payment needs SDLT analysis.
Why this can be difficult in practice
The label does not decide the answer. A side payment, works promise, or another benefit may form part of the price for the rent cut, even where the lease variation itself looks simple.
- A rent reduction is not automatically outside SDLT.
- No payment can still leave a land transaction.
- Side agreements can change the result.
Key takeaways
- A lower rent can have SDLT consequences.
- No payment or valuable benefit can mean an SDLT exemption.
- Check the whole bargain, not just the rent clause.

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 HMRC page contains no substantive explanation of rent reductions.
- The supplied legislation is current only to 17 November 2025, so a variation after that date needs current-law verification.
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 variation and its effective date.
- Details of any cash payment, benefit, works promise or side agreement.
- Records showing why the landlord agreed to reduce the rent.
