Linked leases where an earlier lease was before SDLT
Earlier leases can still matter
A lease from before SDLT began is excluded from the special successive-lease rule. However, if it links to a later SDLT lease, its NPV may still be included when working out the later lease’s SDLT bands.
- The old lease is not charged to SDLT
- The combined NPV affects the rate calculation
- Only the later lease bears the SDLT charge

Linked leases where an earlier lease was before SDLT
Although an old lease granted before 1 December 2003 is not taxed again by SDLT, its rent value may still affect the rate calculation for a later lease. Only the later lease is charged.
What this rule is about
SDLT links leases within one wider deal. This matters for rent duty. Stamp duty on rent uses a net present value, or NPV. NPV puts a value today on rent due over the lease term.
Successive linked near-identical-premises leases have special rules. However, that rule leaves out a lease from before SDLT started.
What the official source says
According to HMRC’s manual, the ordinary linked-lease calculation applies instead. When working out which rates and thresholds apply, it adds the NPV of the old lease to the NPV of the later SDLT lease.
- Execution must predate 1 December 2003.
- SDLT must cover the later lease.
- They must form one scheme, arrangement or series.
- Both leases’ NPV figures are added for the rate calculation.
- Rates and thresholds come from the later SDLT lease.
- SDLT does not charge the earlier lease itself.
What this means in practice
Earlier rent can raise later SDLT bands. That may feel odd, since the old lease was under the former stamp duty system. It affects calculation, not new SDLT charges.
This is the key distinction: HMRC works out tax by looking at both rent values, then charges only the share that belongs to the new lease.
- Do not simply ignore an earlier lease because it predates SDLT.
- Do not submit an SDLT charge for the old lease.
- Keep the NPV calculation for each lease separate.
- Check the rate table that applied when the later lease took effect.
How to analyse it
Start with the timeline. Then consider the commercial link between the leases. A shared property address alone may not settle the point.
- Identify the date each lease was granted or executed.
- Confirm that the earlier lease was before 1 December 2003.
- Check whether the later lease is within SDLT.
- Ask whether both leases form one planned series between the same or connected parties.
- Calculate the NPV of rent under each lease.
- Add those figures to identify the relevant SDLT bands.
- Apply the resulting calculation only to the later lease’s NPV share.
Example
Imagine Priya held a lease from 2002 with an NPV of £100,000. In a linked arrangement, she takes a new SDLT lease with an NPV of £200,000. Because the later lease represents two-thirds of that total, HMRC identifies the SDLT bands using £300,000 but calculates SDLT only on the two-thirds share represented by that later lease. No SDLT charge arises on the 2002 lease.
Why this can be difficult in practice
People often focus only on the later document. That is risky. An earlier lease may change the result even though SDLT cannot charge it directly.
Often, the harder question is whether the leases are truly linked. Written agreements, shared negotiations, party relationships and the timing of the leases can all matter.
- An old lease does not automatically make every later lease linked.
- Calling documents separate leases does not end the enquiry.
- The NPV calculation may need detailed rent information.
- Later law changes may alter rate tables, although the old lease remains pre-SDLT.
Key takeaways
- A pre-December 2003 lease is not itself charged to SDLT.
- Its rent value can still affect a linked later lease.
- Check both the link between leases and the later lease’s date.

Legislation
- FA 2003 section 108 — when land transactions form a linked series
- FA 2003 Schedule 5 para 2 — calculating stamp duty on rent for linked leases

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
- Whether two leases form one scheme, arrangement or series can depend on the documents and surrounding facts.
- The correct rates and thresholds depend on the effective date and type of the later SDLT lease.
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.
- Copies of both leases and any agreements linking them
- The grant dates and effective dates of each lease
- Details of the landlord, tenant and any connected parties
- A schedule showing rent and the net present value for each lease
- Evidence of the commercial arrangements behind the leases
