Land Transaction Tax relief when you buy more than one home
If you buy two or more homes in Wales together, you may get Land Transaction Tax relief. People often call it multiple dwellings relief. The relief can reduce your stamp duty bill, but it never removes it completely.
What this rule is about
One deal for several homes can bring a high tax bill. Without relief, you pay tax on the full price as one purchase. With this relief, the tax calculation instead starts with the average price per home.
That can cut the bill.
The Welsh Revenue Authority treats separate linked purchases under this rule too. In simple terms, purchases are linked when the same buyer and seller, or connected people, make them as one scheme, arrangement or series.
This matters because separate contracts do not always keep a deal outside the rule.
What the official source says
The Welsh Revenue Authority says the relief is available when you buy several homes from the same seller in one purchase, or through linked purchases. When parties make the purchases as one transaction, they must have the same effective date.
- There must be at least two homes in the relevant purchase or linked group.
- The homes can be bought with other land or property.
- Divide the price for the homes by the number of homes.
- Work out tax on that average amount, then multiply it by the number of homes.
- Tax separately any part of the price for land or property that is not a home.
- Use the higher residential rates in the averaging calculation if they apply.
- An off-plan home can count, even if building work has not started by the effective date.
The relief has a floor. You must pay whichever is higher: the tax produced by the averaging method or the applicable minimum percentage of the amount paid for the homes.
For purchases with an effective date before 13 February 2026, the official source says the minimum is 1%. That rate can also apply to purchases covered by the transitional rules.
For purchases on or after that date, the source says the minimum is 3% unless transitional rules apply, so you must check whether those rules cover the purchase before using that rate.
Check them first.
What this means in practice
The average-price method can help most where the homes have different values. It stops a lower-value home from pushing all of the price into higher tax bands.
But it is not a tax-free route.
- Work out whether the deal contains at least two separate homes.
- Determine whether another contract with the same seller forms a linked purchase.
- Identify any shop, field, office or other non-home element.
- Split the price fairly between the homes and everything else.
- Use the higher residential rates if they apply to your purchase.
- Compare the calculated figure with the minimum tax amount.
- Use relief code 50 in the Land Transaction Tax return, as the official source directs.
The code is an administrative instruction from the Welsh Revenue Authority. The relief itself comes from legislation, and the facts must still support the claim.
How to analyse it
Analyse the deal’s shape first. Calling part of a building a flat, annex or unit does not settle whether it is a separate home for this purpose.
- First, list every property interest being bought.
- Next, decide how many separate homes are included.
- Then, check for other linked purchases involving the seller or connected parties.
- Identify the effective date for each relevant purchase.
- Check whether the deal includes non-home land or property.
- Allocate the total price on a just and reasonable basis.
- Calculate the tax using the average price per home.
- Finally, compare that result with the correct 1% or 3% minimum.
There is one important lease limit. A superior interest in a home subject to a lease granted for an initial term of more than 21 years normally cannot count for this relief.
Example
Imagine Aled buys two homes in Wales from one seller for £500,000. There is no other land in the deal. The average price is £250,000 per home. If tax calculated from that average and then multiplied by two comes to £12,000, Aled must compare it with the minimum.
Assume the effective date is after 13 February 2026 and no transitional rule applies. Three per cent of £500,000 is £15,000. Aled pays £15,000 because it is higher than £12,000.
Change the date and the answer may change. For an earlier purchase, or one within the transitional rules, the official source may instead set the minimum at 1%.
Why this can be difficult in practice
The calculation is usually not the hard part. The difficult question is often whether the facts show two genuinely separate homes, or instead show that contracts which look separate form part of the same linked arrangement.
That distinction matters.
Price allocation can also matter a great deal in a mixed deal. A large garden, commercial unit or parcel of land may need a fair value of its own.
- Do not assume separate contracts mean separate tax calculations.
- Do not assume the whole price can be averaged where other property is included.
- Do not overlook the minimum tax rule.
- Do not use the 1% minimum for a later purchase without checking the transitional rules.
- Do not count a superior interest merely because the property is residential.
- Do not assume unfinished work prevents an off-plan home from qualifying.
If your solicitor has said the higher rates apply, that does not stop the relief being relevant. The higher rates may be part of the relief calculation.
Key takeaways
- Buying more than one home at once can qualify for Welsh multiple homes relief.
- The relief uses an average price, but tax is still due.
- From 13 February 2026, the usual minimum is 3%, subject to transitional rules.

Official guidance
The pages below are the Welsh Revenue Authority’s guidance. Guidance is not law. It sets out how the Welsh Revenue Authority 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. the Welsh Revenue Authority can also change or withdraw guidance, and it may not cover your facts.
Where this is not settled
- The source refers to transitional rules for some purchases around 13 February 2026. Whether they apply depends on the detailed facts and timing of the contract and purchase.
- Where a deal includes land or property that is not a home, the price must be split on a just and reasonable basis. That can require a valuation judgement.
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, completion statement and effective date.
- Details of every home included in the deal.
- Details of any linked purchases and the parties involved.
- A reasonable split of the total price between homes and other property.
- Lease documents where a superior interest is being bought.
- The return showing relief code 50.
