Stamp duty on lease rent: how the NPV calculation works
Rent under a lease may attract stamp duty. The key figure is not simply all the rent added together. SDLT uses the rent’s net present value, often called NPV.
What this rule is about
Because rent due in future is worth less today than the same amount due now, the statutory approach discounts those later payments before bringing them together in a present-day calculation. That is NPV.
The resulting figure determines whether SDLT is due on the rent.
What the official source says
HMRC’s manual explains that SDLT is charged on rent if the NPV exceeds the relevant threshold, with the legislation setting the rate bands for that calculation. Those bands apply.
- Work out the NPV of rent over the lease term.
- Identify whether all the land is residential.
- Use the residential bands if it is entirely residential.
- Use the non-residential or mixed-property bands if it is not.
What this means in practice
Even where annual rent is modest, a lease that lasts a long time can still require an NPV calculation, while total rent alone does not decide the tax. Duration matters.
- Keep the agreed rent schedule with the lease.
- Include changes in rent due across the term.
- Check the property’s category before choosing bands.
- Check the bands and threshold for the relevant date.
How to analyse it
Begin with the lease terms rather than a rough total of payments, because the statutory NPV calculation and the correct property category are what matter. Start there.
- Find the start date and length of the lease.
- List the rent payable for each year.
- Calculate the NPV under the statutory method.
- Compare that figure with the correct current bands.
Example
Suppose a lease has an NPV of £240,000. That does not, by itself, show the tax due. You must first decide whether the land is wholly residential, then use the rate bands in force for that type of property.
Why this can be difficult in practice
People often add up every future payment and treat that as the SDLT figure. That is not the statutory method. The lease length, changing rent and property type can all affect the result.
- Future rent is discounted in the NPV calculation.
- A mixed property lease uses different bands.
- Current thresholds can change, so old figures may be wrong.
Key takeaways
- SDLT on rent uses NPV, not just total rent.
- Property type affects the rate bands used.
- Check the rates in force on the relevant date.

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
- This page does not state the current rate bands or thresholds. They must be checked for the relevant transaction date.
- The supplied legislation is current only to 17 November 2025, so later changes require checking against the official legislation.
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 lease term
- the rent due for each year of the term
- whether all the leased land is residential
- the transaction’s relevant date
