Stamp duty on a five-year market rent review: when it may be ignored
Five-year rent reviews and SDLT
A first market-rent review may be left out of the initial SDLT rent calculation when it falls near the end of the first five years and meets strict conditions.
- Check the grant date, term start date and review clause.
- The review must be the first or only uncertain adjustment.
- HMRC’s practical approach is guidance, not legislation.

Stamp duty on a five-year market rent review: when it may be ignored
Stamp duty on a five-year market rent review: when it may be ignored
A market-rent review close to the fifth year of a lease can alter the stamp duty calculation. Taxpayers may exclude it from SDLT on the rent in a narrow set of cases. Dates matter here. A gap of days can produce a different result.
What this rule is about
Stamp duty land tax on a lease can include tax on the rent, not just any upfront payment. You calculate it by taking the rent over the lease term and discounting it to a present-day value. Tax professionals call this net present value, or NPV.
Later rent can be uncertain when the lease starts, which creates a problem with variable rent. Normally, calculations consider the first five years. You then use the highest annual rent from that period for later years.
One kind of review near year five has a special rule. That rule moves the end of the five-year period to the review date. Therefore, you do not have to estimate the unknown reviewed rent for the initial NPV calculation.
This is not a general exemption for rent reviews. Instead, it is a tightly drawn timing rule.
What the official source says
Finance Act 2003 Schedule 17A paragraph 7A applies where a lease itself permits an adjustment to the rent. It applies only to the first, or the only, adjustment under that provision. Before the review, the parties must not know the new rent.
- The lease must contain the rent-review provision.
- The review must be the first or only adjustment under it.
- The new amount must be unknown in advance, such as open market rent.
- The review date must be expressed as five years after a specified date.
- That specified date must fall within three months before the lease term starts.
When the lease contains the clause, the adjustment is first or only, the amount remains unknown, and the dates meet the test, the law treats the first five years as ending on the review date. Practically, the review falls after that measuring period.
HMRC’s manual gives a broader practical view. It says HMRC accepts reviews that fall in the final three months of the fifth year, even if the lease does not use a specified date. That is HMRC’s published approach, not the exact statutory test.
What this means in practice
Use the date the lease was granted as your starting point, not only the date from which its term runs. If the first market-rent review falls late enough, you can use the rent before the review without estimating the new market rent.
That can make the original SDLT calculation simpler. It may also lower the NPV used for that calculation. It does not mean the lease has no SDLT on rent.
- Check the formal grant date.
- Check the stated start date of the lease term.
- Read the review clause rather than relying on a summary.
- Confirm whether market rent, rather than a fixed sum, sets the new rent.
- Check whether an earlier review or adjustment exists.
- Keep the calculation and lease wording with the SDLT papers.
What is the key question? Whether the first uncertain review is late enough under the statutory dates. Calling it a “five-year review” is not enough.
How to analyse it
Work through the lease in date order. A review may appear to fall in year five but still fail if the grant date, the term start date, or the specified date in the clause sets a different relevant starting point. It then fails.
- Identify the date the lease was granted for SDLT purposes.
- Identify the date the term begins.
- Find the first date when rent can be adjusted.
- Decide whether that adjustment produces an uncertain amount before it happens.
- Find the specified date used in the clause, if there is one.
- Measure whether that date is within three months before the term begins.
- Apply the extended period only if every statutory condition is met.
- Then calculate the NPV using the rent required by the relevant rule.
Do not stop at the calendar anniversary. A clause can instead name a date before the grant, which explains this special rule.
Example
Imagine a lease granted on 11 July 2015 for ten years from 25 June 2015. The annual rent is £35,000. The lease sets its first review to open market rent on 25 June 2020, five years after the stated start date.
The start date falls within three months before the grant. The review is the first one, and market rent is unknown beforehand. On those facts, the special rule applies.
Because £35,000 is the highest annual rent in the relevant period, the NPV calculation carries that figure through the whole ten-year term rather than using an estimated reviewed rent. You do not estimate market rent from 25 June 2020.
Now change one fact. If parties granted the lease on 26 September 2015 but began it on 24 June 2015, the start date would be more than three months earlier. The statutory rule would not apply.
Why this can be difficult in practice
Often, the difficult part is not the maths. It is deciding which legal date controls and what the review clause actually says.
An agreement for lease adds another layer. If substantial performance happens before the formal lease is granted, the law can treat it as a notional lease from that earlier date. Parties who later grant a formal lease do not necessarily restart the clock.
- A review described commercially as “five-year” may fail the date test.
- A fixed uplift differs from a market-rent review.
- An earlier adjustment can mean the review is not the first one.
- A lease start date and grant date may be different.
- Substantial performance can create a notional earlier lease.
- HMRC’s final-three-month practice should not be confused with the statutory wording.
People often miss this point: a review three years after the formal lease is granted may still follow a much earlier notional lease. On the source example, that prevents the special rule from applying.
Key takeaways
- For the initial SDLT rent calculation, a first uncertain rent review near year five may be ignored.
- The lease wording, grant date and term start date all matter.
- HMRC’s practical view is wider than the statute’s specified-date wording.

- FA 2003 Schedule 17A para 7 — treatment of variable or uncertain lease rent

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
- HMRC’s practical acceptance of any review in the final three months of the fifth year goes beyond the statute’s express specified-date condition. The statutory wording remains the starting point.
- The supplied legislation is consolidated only to 17 November 2025. A transaction whose effective date is later than that needs a check against current primary 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 signed lease and any side letter that sets the rent review terms.
- The grant date, lease start date and review date.
- Evidence of whether the review is the first or only adjustment.
- The review mechanism, including whether it sets market rent or a fixed amount.
- For an agreement for lease, the date it was substantially performed and the dates in the eventual lease.
