SDLT and stamp duty on variable or uncertain lease rent
Variable lease rent and SDLT
The archived HMRC page provides no worked example. For England and Northern Ireland, the lease terms and the first five years of rent drive the analysis.
- Check every rent-change clause.
- Record the highest 12-month rent in the first five years.
- Reconsider the result when uncertain rent becomes known.

SDLT and stamp duty on variable or uncertain lease rent
The HMRC page called “Example 7” no longer contains an example. It now says only that SDLT no longer covers Scottish land transactions from April 2015.
The page supplies none of the example its title might lead readers to expect. Nothing more appears. In England and Northern Ireland, stamp duty on lease rent can still depend on how rent changes during the term, even if the initial figure seems straightforward. The lease controls.
What this rule is about
A lease may provide for rent that rises, depends on future events, or cannot yet be fixed. SDLT needs a figure at the start. The law therefore provides a method for working out the rent used in the calculation.
What the official source says
Although HMRC’s archived page presents itself as an example, it gives no figures, lease terms or explanation for the stated example. The underlying calculation is therefore unavailable. It only flags the move from SDLT to LBTT in Scotland from April 2015.
- The page does not show the original Example 7 facts.
- It does not show HMRC’s calculation.
- It does not change the law for England or Northern Ireland.
What this means in practice
Do not regard the page title as a worked answer when the page gives neither facts nor a calculation, however strongly the label may seem to promise one. Read the lease.
For rent after year five, the law uses the highest rent due for any consecutive 12-month period in the first five years.
- List the rent due in each part of the first five years.
- Check whether a clause makes the rent depend on a future event.
- Ignore an adjustment that only follows the retail prices index.
How to analyse it
Consider one question at a time: what does the lease require, and when does the amount become clear?
- Identify every clause that can change the rent.
- Estimate uncertain rent in the first five years on a reasonable basis.
- Find the highest 12-month rent within those five years.
- Use that amount for later years in the SDLT rent calculation.
Example
Suppose a ten-year lease charges £10,000, £12,000, £15,000, £12,000 and £10,000 in its first five years. The calculation must compare those changing amounts before considering later rent.
Take the peak. For later years, use £15,000 a year when working out the rent figure. This illustrates the statutory method, not the missing HMRC example.
Why this can be difficult in practice
The drafting often creates the difficulty. A clause that seems to be a simple review can still leave the amount uncertain until conditions outside the lease are resolved.
That matters. When the uncertainty ends, the SDLT result may need another look.
- A turnover-based payment may need an estimate.
- A rent review date can matter as much as the new rent.
Key takeaways
- The supplied HMRC page has no usable Example 7 content.
- Variable rent needs careful lease-by-lease analysis.
- Later rent usually follows the highest first-five-year amount.
Technical analysis

Legislation
- FA 2003 Schedule 17A para 7 — working out 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
- Without the missing example text, it is not possible to say what facts or calculation HMRC intended to illustrate.
- The correct result depends on the lease wording, the rent in each period, and when any uncertainty ends.
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 every rent-review clause
- A schedule of rent for the first five years
- Details of any event that fixes previously uncertain rent
- The effective date of the lease transaction
