Multiple dwellings relief: the old stamp duty rules
Multiple dwellings relief was a way of working out stamp duty when you bought more than one home. HMRC says it was abolished for most deals that completed, or went far enough to count for tax, on or after 1 June 2024. Old contracts may still need checking.
What this rule is about
This relief for buying more than one home at once was often called multiple dwellings relief. It could reduce SDLT by using an average price per home, rather than taxing the whole price as one purchase.
That sounds simple. It was not always cheaper, and it is no longer available for most new purchases.
For SDLT, the date matters most. The relevant tax date is usually completion. It can be earlier if a contract has been substantially performed, such as where the buyer takes possession or pays most of the price.
What the official source says
HMRC’s manual says the relief ended where a transaction completed or was substantially performed on or after 1 June 2024. It also points to special transitional rules, including rules for linked purchases.
- The former relief covered a purchase of at least two homes.
- It could also apply where separate but linked purchases together involved more than one home.
- You had to claim it. It did not apply by itself.
- The amount paid for the homes was divided by their number.
- SDLT was worked out on that average, then multiplied by the number of homes.
- The tax on the homes could not be less than 1% of the amount allocated to them.
- Any part of the deal that was not a home was taxed under the normal rules.
HMRC also says an off-plan purchase could qualify under the former rules. This is where the contract required a home to be built, even though building had not started when the contract was substantially performed.
Buying bare land with planning permission was different. HMRC’s view is that this did not qualify where there was no contract obligation to build a home.
What this means in practice
If you are buying homes now, do not assume this relief can reduce your bill. From 1 June 2024, the starting point is that it ended. Check the tax date before looking at the old calculation.
A pre-1 June 2024 contract may need more work. Special transitional rules can matter, especially where one deal is connected with another purchase.
- Keep the signed contract and any variations.
- Check the completion date.
- Check whether possession, payment, or another event happened earlier.
- List each home included in the deal.
- Separate the price for homes from the price for other land or buildings.
- Check whether another purchase forms part of the same arrangements.
Buying six or more homes in one transaction gave a separate choice under the legislation. They could be treated as non-residential property for SDLT. Where that route and the former relief were both open, the buyer could choose the cheaper result.
Extra stamp duty that can apply to a second home did not prevent the former relief. Instead, the higher rates were used when working out tax on the average price.
How to analyse it
Work through the dates first. There is little value in doing a detailed old calculation if the relief was already abolished for your deal.
- What is the SDLT tax date for the transaction?
- Did it complete, or become substantially performed, before 1 June 2024?
- Do transitional rules apply to the contract or related purchases?
- How many separate homes did the purchase include?
- Was any part of the price for land or buildings that were not homes?
- For an off-plan deal, did the contract require a home to be built?
- Would the six-or-more-homes route give a lower SDLT result?
- Could higher rates or non-UK resident rates affect the calculation?
This is the part people miss: planning permission alone was not the same as a contractual promise to build. Contract wording could decide the answer.
Example
Imagine Priya agreed before 1 June 2024 to buy two completed flats for £400,000 in one deal. If the former relief applied, the starting calculation used £200,000 per flat, then multiplied the tax result by two. Tax could not fall below 1% of the £400,000 allocated to the flats: £4,000.
Change one fact. If Priya instead bought a plot with planning permission for two flats, but nobody was obliged under the contract to build them, HMRC says that was not an off-plan purchase for this relief.
These figures only show the method. Actual SDLT bands and any extra rates depend on the tax date and the buyer’s circumstances.
Why this can be difficult in practice
Many older claims turn on records rather than a simple property count. A flat above a shop, a house with an annexe, or land bought with a building plan can raise hard questions about what the deal really included.
- A contract date alone may not settle the SDLT tax date.
- Several documents may need reading together for an off-plan deal.
- The price split between homes and other property must be fair.
- Linked purchases can change both eligibility and the calculation.
- A later change that reduces the number of homes can increase the tax due.
- Long leases above the stated limit could prevent a superior interest from qualifying, except in limited shared-ownership cases.
Under the former rules, a later event within three years could trigger a recalculation if it meant more tax would have been due at the start. Legislation required the buyer to make a further return and pay the extra tax within 30 days of that event.
HMRC’s manual explains its view, but it is not the law itself. Contracts, the statutory transitional rules, and the facts remain the starting point.
Key takeaways
- Multiple dwellings relief ended for most transactions from 1 June 2024.
- Older contracts may still fall within special transitional rules.
- For qualifying historic deals, SDLT used the average price per home.
- The former calculation had a 1% minimum tax amount.
- Planning permission without a building obligation was not enough on HMRC’s view.

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 transitional rules preserve the former relief depends on the dates and terms of the particular contract and any linked purchases.
- Whether a building, part of a building, or planned home counts as a separate home can depend on the facts and contract documents.
- Current primary legislation should be checked before relying on the continuing position after 17 November 2025.
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 signed contract and completion statement
- The date of completion and any earlier substantial performance
- Details of every home included in the deal
- Plans, specifications and building obligations for an off-plan purchase
- Details and prices of any non-home land or buildings
- Details of any connected or linked purchases
- Evidence of any later event that reduced the number of homes
