How historic multiple dwellings relief split the stamp duty calculation
How historic multiple dwellings relief split the stamp duty calculation
HMRC says it abolished the relief when completion, or substantial performance, occurred on or after 1 June 2024, although a qualifying transitional case may still require the historic calculation. Most new purchases cannot use it. This page explains the old stamp duty calculation, which can still matter for a qualifying transitional case.
What this rule is about
The former relief changed the way buyers worked out SDLT when they bought more than one home at once, rather than simply removing stamp duty from the transaction. It altered the calculation.
When a purchase included homes and other property, buyers had to divide the amount paid between them before calculating tax for each part and adding the results together. That split could make a real difference.
When homes sit alongside a shop, office, yard or land with another use, do not treat the full price as the price of the homes because those assets may form separate parts of the deal. Separate parts matter.
What the official source says
HMRC’s manual says that the calculation has two parts. First comes the amount paid for interests in homes. Second comes any amount left over.
- Split the amount paid between the homes and any other property.
- Use a just and reasonable basis for that split.
- Work out the tax connected with the homes.
- Work out the tax connected with the remaining amount, if there is one.
- Add those two amounts together.
- Use the normal lease rules if rent was part of the amount paid.
The statute contains a more detailed formula for the homes part, starting with the total amount for the homes divided by their number before applying residential SDLT. You then multiply that SDLT result by the number of homes.
There is also a statutory minimum: the homes part cannot be less than 1% of the total amount allocated to the homes. This was part of the historic calculation, not a new relief.
What this means in practice
The key task is often the allocation. Calling a property “mixed use” does not settle it. You need a fair figure for the homes and a fair figure for everything else.
HMRC’s manual also flags cases where the price used for SDLT is not simply the cash price. Market value can replace or increase the amount used in some connected-company deals, exchanges and partnership arrangements.
- Keep the contract and plans showing exactly what was bought.
- Identify each home included in the purchase.
- Identify land or buildings that were not part of those homes.
- Record how you divided the total price between those parts.
- Keep valuation evidence that supports the division.
- Check whether rent was payable under a lease.
If rent was included, it is not folded into this split in the usual way. Schedule 5 has its own rules for tax on rent. That tax is separate from SDLT on the price or other non-rent amount.
How to analyse it
Start with timing. This is the point many people now miss: HMRC abolished the former relief for most transactions from 1 June 2024.
- Check the completion date and whether the contract was substantially performed earlier.
- Check whether a special transitional rule could preserve the old relief.
- Check whether the purchase involved more than one home and qualified for the former relief.
- List all other property included in the same deal.
- Work out a just and reasonable split of the amount paid.
- Apply the historic homes calculation to the homes part.
- Calculate the remaining part under the applicable SDLT rules.
- Calculate any rent under the lease-rent rules.
- Add the amounts together.
For linked purchases, the calculation can change because the legislation looks across the linked transactions. The supplied HMRC page points readers to separate guidance on those transitional linked-transaction rules.
Example
Before the abolition date, Priya bought two flats and a small shop in one deal, requiring a just and reasonable division between the homes and the shop. She paid £1,000,000. A just and reasonable split puts £800,000 with the two flats and £200,000 with the shop.
The historic homes calculation starts with £800,000 divided by two: £400,000 per flat. The SDLT result on that average is then multiplied by two, subject to the statutory minimum. The remaining £200,000 is dealt with separately. The two tax amounts are then added.
The example gives no rate because SDLT rates depend on the effective date and the facts, while its purpose is to show how the split affects the calculation. Its point is the split: £1,000,000 is not treated as one undivided amount.
Why this can be difficult in practice
A fair split is not always obvious when a building contains homes, business space, shared access and land used in more than one way, but the contract gives only one total price. That creates a valuation issue.
You might think separate prices written into a contract settle the issue. They do not necessarily do so. SDLT requires a just and reasonable allocation based on the real bargain.
- A single price may need to be divided using reliable valuation evidence.
- The number of homes affects the historic formula.
- Linked deals may require figures to be considered together.
- A lease can create a separate rent calculation.
- Market value rules can change the figure used for SDLT.
- Transitional rules decide whether the abolished relief remains available at all.
Key takeaways
- Multiple dwellings relief was abolished for most transactions from 1 June 2024.
- For an eligible historic case, split the price fairly between homes and other property.
- Work out the homes, remaining-property and rent elements separately where 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
- The supplied statutory extract still contains Schedule 6B, while HMRC’s source page says the relief was abolished from 1 June 2024. Current primary legislation and the relevant transitional rules must be checked before publishing or relying on a current-law conclusion.
- A just and reasonable split is fact-sensitive. The legislation does not prescribe one universal valuation method.
- The source page does not set out the special transitional rules or the detailed rules for linked transactions.
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.
- completion date and any date of substantial performance
- contracts and details of any linked purchases
- a breakdown of the property bought, including non-home elements
- evidence supporting the proposed just and reasonable allocation
- lease terms and rent details where rent was part of the deal
- details of any exchange, connected company, or partnership election
