Stamp duty when flat tenants buy their block freehold
In brief
For a qualifying collective purchase of a block freehold, SDLT is generally calculated by dividing the price between participating qualifying flats first.
- Use the number of qualifying participating flats.
- Check the £500,000 per-flat figure.
- Check the buyer structure before applying the 17% charge.

Stamp duty when flat tenants buy their block freehold
When flat tenants join together to buy their block freehold, stamp duty is not always worked out on the total price in the usual way. The law first splits the price between the qualifying flats. That can make a major difference.
What this rule is about
This rule covers a group purchase of a block freehold through a right of first refusal or collective enfranchisement. Collective enfranchisement means leaseholders joining together to buy the freehold.
It is not enough that several tenants happen to buy a building together. They must use one of those legal rights, and the buyers must be people nominated or appointed by the participating tenants.
What the official source says
HMRC’s manual describes the statutory calculation. The law divides the total amount paid by the number of qualifying flats, works out SDLT on that figure, then usually multiplies the result by that number.
- For these purposes, a qualifying flat is one held by a qualifying tenant who is taking part in the purchase under the relevant route. That status matters.
- Divide the total amount paid for the freehold by those qualifying flats.
- Where the result is £500,000 or less, apply the ordinary SDLT bands to that result before proceeding with the statutory calculation. Then continue.
- Multiply that SDLT figure by the number of qualifying flats.
- If the result exceeds £500,000, check whether the company or similar-buyer condition applies.
- If it does, SDLT is 17% of the total amount paid.
What this means in practice
In practice, the key figure is not simply the price of the whole block, because the calculation turns on the price per qualifying participating flat. That is the focus.
A block worth more than £500,000 can still use the ordinary calculation. That distinction sounds small. It can change the tax by a large amount.
- Count participating qualifying flats, not every flat in the building.
- Keep clear evidence of which tenants took part.
- Check who will legally buy the freehold before agreeing the structure.
- Build the correct SDLT figure into the money needed to complete.
How to analyse it
Start with the legal route for the purchase. Then work through the calculation in order. Do not begin by assuming that a company buyer automatically means 17%.
- Is the purchase made under the right of first refusal or collective enfranchisement?
- Who has been nominated or appointed to buy the freehold?
- Which flats are held by qualifying tenants who are taking part?
- What is the total amount paid for the freehold?
- What is the amount per qualifying flat?
- Is that figure above £500,000?
- If it is, ask whether the buyer is a company, a relevant partnership, or a collective investment scheme, because that status determines whether the condition applies. Check it.
Example
Three qualifying tenants buy their block freehold for £1.2 million. The figure per qualifying flat is £400,000. Using the ordinary residential SDLT bands, tax on £400,000 is £10,000. Multiply that by three: SDLT is £30,000.
Now change the price to £1.8 million. The figure is £600,000 per qualifying flat. Where the Schedule 4A company condition is met, the result is instead 17% of £1.8 million: £306,000. That is the outcome.
Why this can be difficult in practice
This is the part people get wrong: the divisor is the number of qualifying participating flats. It is not automatically the number of flats shown on the building plans.
- A tenant may own a flat but not take part in the purchase.
- The group may include buyers with different legal roles.
- A company acting as trustee has special treatment under the company condition.
- Joint buyers can also affect whether that condition is met.
- The separate law governing the tenants’ collective right may need close checking.
Key takeaways
- Split the block price by qualifying participating flats first.
- £500,000 is the key per-flat figure in this calculation.
- The 17% charge applies only where the figure is above that amount and the relevant buyer condition is also met under the statutory test. Both are required.

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
- This page does not decide whether particular tenants, flats or arrangements meet the separate legal rules for a right of first refusal or collective enfranchisement.
- The source does not address whether any separate relief or different rule applies to the facts of a particular 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 legal route used to buy the freehold
- The nomination or appointment documents
- The number of flats and which participating tenants hold them
- The total amount paid for the freehold
- The identity and legal status of every buyer
