Stamp duty on a second home: the 21-year lease rule
The 21-year lease point
For Condition B, the higher-rates test looks at the exact interest you buy and any lease above it.
- No lease above the interest: Condition B is met
- Lease with 21 years or less left: Condition B is met
- Lease with more than 21 years left: Condition B is not met

Stamp duty on a second home: the 21-year lease rule
A long lease above the interest you buy can stop the higher stamp duty rates applying under this test. The key question is not simply whether you buy a freehold or leasehold: it is whether the exact right you buy is subject to a lease with more than 21 years left. That is the issue.
What this rule is about
Condition B, which deals with layered ownership where a building may have a freehold owner, a head leaseholder and an underleaseholder holding different rights in the same property, is one part of the higher-rates test for a person buying one home. It can decide the tax result.
That distinction may sound technical. It can decide the tax result.
The law tests the interest you are buying on its effective date. Normally, this is the completion date, although other rules can set a different date in some cases.
What the official source says
In line with paragraph 3 of Schedule 4ZA, HMRC’s manual explains Condition B and says that it is met where the home interest you buy is not subject to a lease. There is another case. It is also met if it is subject to a lease with no more than 21 years left before it ends.
- A freehold with no lease above it meets Condition B.
- A leasehold interest with no lease above it meets Condition B.
- An interest subject to a lease with 21 years left meets Condition B.
- An interest subject to a lease with more than 21 years left does not meet Condition B.
In this context, “subject to” means that another lease sits above the right you are buying, while the reversionary interest you buy gives you a right that will take effect when that earlier lease ends. That timing matters.
HMRC’s manual is not law. The legislation is the legal test, and it uses the same 21-year dividing line.
What this means in practice
If Condition B is not met, the purchase cannot be a higher-rates transaction under paragraph 3. That may be helpful where a buyer has other property. Still, Condition B is only one part of that paragraph, and Schedule 4ZA has other tests.
Do not stop at the word “freehold”. A freehold can be subject to a long lease. Equally, the leasehold right being bought may not itself be subject to any lease.
- Check the interest named in the contract.
- Read the title register, not just the estate agent’s description.
- Find the expiry date of any lease above that interest.
- Count the term left on the effective date.
How to analyse it
Start with the ownership structure. Then work upwards through any leases. What matters is the lease immediately affecting, or sitting above, the particular right you are buying.
- Identify whether you are buying the freehold, a head lease or an underlease.
- Ask whether that exact interest is subject to another lease.
- If it is, work out how many years remain when the transaction takes effect.
- Compare that period with 21 years.
- Only then consider the other higher-rates conditions that may apply.
What people often miss is that three interests in the same house can produce different answers, because each interest is tested separately against the lease to which it is subject. They are separate rights.
Example
Imagine that Priya buys the freehold of a property. An existing lease has 80 years left to run. The freehold is subject to that lease, and 80 years is more than 21 years. Condition B is not met for Priya’s purchase.
Now change one fact. Priya buys the leasehold interest instead. That interest is not itself subject to another lease, so Condition B is met. This alone does not settle the whole higher-rates question, but it changes this condition’s answer.
HMRC gives a further layered example. A freehold is subject to a 999-year head lease with 950 years left, and that head lease is subject to an underlease with 50 years left. Buying the freehold or head lease does not meet Condition B. Buying the underlease does meet it.
Why this can be difficult in practice
Property papers can describe a home loosely while the legal title shows several separate interests, so a long lease may be easy to overlook, especially where the buyer is told they are acquiring the “freehold”. This can matter.
You might think the longest lease always decides the issue. It does not. The test focuses on the interest you are actually buying and the lease to which it is subject.
- A lease can be relevant even where you are buying a freehold.
- A short underlease can meet the condition despite a much longer head lease above it.
- The remaining term must be tested on the effective date, not an earlier viewing or offer date.
- Condition B does not by itself decide whether higher rates apply overall.
Key takeaways
- Check the exact interest you are buying.
- A lease with more than 21 years left can prevent Condition B being met.
- Read every layer of the title before reaching a stamp duty answer.

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
- Working out which lease sits above the exact interest being bought can require close reading of the title and lease documents.
- This page does not determine whether another Schedule 4ZA paragraph could apply to a purchase.
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 contract, transfer and completion details
- The title register for the interest being bought
- Every lease above or affecting that interest
- The expiry date and remaining term of each relevant lease
