The £40,000 test for stamp duty on a second home
The £40,000 gateway test
For a single-home purchase, Condition A requires the amount given for the interest bought to be at least £40,000. It is not a 0% stamp duty band.
- A share purchase is tested by reference to the interest acquired.
- The full value of the property is not automatically the relevant figure.
- Other higher-rates conditions must still be checked.

The £40,000 test for stamp duty on a second home
Extra stamp duty rules for a second home do not start below £40,000. You must pay at least £40,000. This is not a tax-free slice. If the higher rates apply, they apply to the full amount.
What this rule is about
Condition A is one part of the test for the SDLT higher rates for additional homes. They are higher stamp duty rates that can apply when you buy a home while owning another one.
That £40,000 figure is a gateway test. It stops very low-value purchases from meeting this part of the test. It does not settle the whole question.
What the official source says
Under the law, Condition A is met when the chargeable consideration, meaning the value given for the purchase in that transaction, reaches £40,000 or more. That is the threshold. HMRC’s manual says that, if you buy only a share, the test looks at the value of the interest you acquire.
- The amount for a single-home purchase must be £40,000 or more.
- Buying part of a home does not mean you use the full value of that home.
- You test the value of the share or interest you are buying.
- £40,000 is not an allowance that is taxed at 0%.
- If the higher rates apply, they apply to the whole amount for the purchase.
What this means in practice
A home may be worth far more than £40,000, yet when you acquire only a share, the relevant figure is what you give for that particular interest. Whole value is not decisive.
Here is the point people can get wrong: passing the £40,000 test does not automatically mean you must pay the higher rates. It only means Condition A is met.
- Check the price or other value given for the interest you buy.
- Do not treat the first £40,000 as free of the higher rates.
- Check the other conditions for the higher rates separately.
How to analyse it
Begin with the legal deal rather than an estate agent’s estimate of the whole property, because the interest acquired and consideration given determine this test. Start there. Your contract and transfer papers should identify exactly what you are buying and what you are giving for it, so the legal deal can be tested. Details matter.
- Is this a purchase of one home for the Schedule 4ZA test?
- Are you buying all of it, or only a stated share?
- What is the amount given for that interest?
- Is that amount at least £40,000?
- If it is, do the other higher-rates conditions also apply?
Example
Amir buys a 25% share in a flat. Although the flat is worth £160,000, Amir gives £39,000 for his share. On HMRC’s view, Condition A is not met because the interest he acquires is below £40,000. If he instead gives £45,000 for that share, Condition A is met. Whether the higher rates apply would still depend on the other conditions.
Why this can be difficult in practice
A stated cash price may not tell the full story. A deal can include a debt taken over, a payment made later, or linked arrangements. The documents matter.
You should not assume a share has the same value as the matching percentage of the whole property. Terms of the interest bought can matter.
- A whole-property value is not necessarily the figure for a share purchase.
- A low cash payment may not be the only value given under the deal.
- Meeting Condition A is not the same as meeting every higher-rates condition.
Key takeaways
- The £40,000 test is a gateway, not a tax allowance.
- For a share purchase, HMRC says to look at the interest acquired.
- The higher rates apply only if the full statutory test is met.

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
- A contract may include payments, debts taken over, or other value besides the stated cash price. The documents must show what is given for the share being bought.
- Where a price covers more than one asset or interest, the facts and contract may need careful review to identify the amount for the interest acquired.
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.
- Signed purchase contract — the price, parties and exactly what share or interest is being bought
- Transfer deed or share transfer document — the legal interest transferred and the buyer’s percentage share
- Completion statement from the conveyancer — the money paid on completion and any sums adjusted or retained
- Mortgage offer and completion records — whether borrowing funded the purchase and any debt taken on
- Land Registry title and filed plan — the registered property, ownership structure and any relevant leasehold interest
- Trust deed or declaration of trust — the beneficial share bought where legal and beneficial ownership differ
- Correspondence agreeing the price — whether the stated price relates only to the share or to wider arrangements
- SDLT return and calculation — the figure reported to HMRC and how the higher-rates test was applied
