Stamp duty on lease rent: the HMRC rent calculation guide
SDLT on lease rent
HMRC’s page is a directory to its guidance on calculating SDLT on lease rent. The legal calculation uses the rent’s net present value rather than its simple cash total.
- Check the full rent pattern and lease term.
- Take special care with variable or uncertain rent.
- Verify the bands and rates for the relevant transaction date.

Stamp duty on lease rent: the HMRC rent calculation guide
Stamp duty land tax can apply to rent under a lease, not just to a premium paid at the start.
The rent is not simply added up. SDLT uses a discounted figure called net present value, or NPV.
What this rule is about
This HMRC page is a contents page. It points to manual pages explaining how to work out SDLT on lease rent in England and Northern Ireland.
The idea is simple: money due far in the future is worth less today, so SDLT uses the present value of rent due across the lease term.
It then tests that figure against the rent bands.
This calculation is separate from SDLT on a lease premium or another upfront payment. A lease can involve both calculations.
What the official source says
HMRC’s contents page lists guidance on rent calculations. It covers the basic NPV method, part-years, rate bands, and many forms of rent that may change or remain unknown at the start.
- Rent and the NPV calculation
- Manual NPV examples
- Leases whose term includes part of a year
- Rent rate thresholds and examples
- Rent that varies or cannot yet be fixed
- Rent reviews, including certain five-year reviews
- Turnover rent linked to a tenant’s sales
- Rent linked to an index
- Royalty payments and payments for mineral extraction
The legislation, not the manual, sets the legal method. It says the relevant rental value is the NPV of rent due over the lease term.
It also sets a 3.5% annual discount rate.
Variable or uncertain rent needs particular care in the first five years, while for later years the law generally assumes annual rent equals the highest amount due in any consecutive 12-month period within those first five years.
That assumption can matter.
What this means in practice
The key question is not just, “What is the yearly rent?” You need the full payment pattern over the term.
A rent-free period, a step-up in rent, or a review clause can change the result.
- Keep the full rent schedule, not only the first year’s figure.
- Check whether the lease lasts for whole years or includes part of a year.
- Separate rent from any premium or other upfront sum.
- Check whether rent depends on sales, production or another future event.
- Check whether more than one lease is linked to the same deal.
You might think an index-linked rent must be estimated for every future year. The legislation has a specific rule for rent adjusted in line with the retail prices index.
The clause wording still matters.
How to analyse it
Start with the lease documents. Do not begin with a calculator.
The calculation only works when the rent figures and lease term are right.
- Identify the date the lease begins and its stated term.
- List rent due for each year, including any part-year.
- Identify rent-free periods, stepped rent and fixed reviews.
- Ask whether any amount is contingent, uncertain or not yet known.
- Check whether the lease contains turnover, royalty or index-linked rent.
- Calculate the NPV using the statutory discount method.
- Apply the rent bands that applied on the relevant date.
- Consider whether linked leases change the calculation.
If a rent figure later becomes known, you may need to reconsider the SDLT position, because the law includes rules for a further return when more tax becomes due and routes for correcting an overpayment.
Check again then.
Example
Imagine Priya takes a five-year lease. The rent is £10,000 at the end of each year, with no premium and no review clause.
The cash total is £50,000. But the NPV is lower because each future payment is discounted at 3.5%.
Using the statutory method, the NPV is about £45,761. This shows the point: SDLT on rent starts with the discounted value, not the £50,000 cash total.
Whether any SDLT is due then depends on the correct rent bands for the transaction date and the type of property.
Why this can be difficult in practice
Most problems come from the lease wording, not the arithmetic. A clause may look like a normal rent review but actually make the amount depend on future sales, prices or output.
- A turnover clause can make rent depend on future trading.
- A royalty may be rent for SDLT purposes, depending on the arrangement.
- A review date close to the fifth anniversary has a special rule.
- Linked leases may need to be considered together.
- A later change in what is known may alter the SDLT result.
HMRC’s linked manual pages may help show its approach. They do not replace the legislation.
This contents page does not answer every drafting question.
Key takeaways
- SDLT can apply to lease rent as well as an upfront premium.
- The starting figure is the rent’s net present value, not its cash total.
- Variable, turnover and uncertain rent need extra checks.

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 contents page does not explain the detailed facts needed to decide whether rent is variable, contingent, uncertain or unascertained.
- The supplied legislation is verified only to 17 November 2025. Current-law checks are needed 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 side letters
- The lease start date and length
- A rent schedule showing each payment period
- Details of rent reviews, index links and turnover-based rent
- Details of any linked leases or other linked deals
