LTT on six or more homes and mixed-use property in Wales
If you buy six or more homes in one deal, Welsh Land Transaction Tax can use the non-residential rates instead of the residential rates. Buying mixed-use property, such as a shop with a flat above it, has the same result. This can make a large difference to the stamp duty-style tax due in Wales.
What this rule is about
Land Transaction Tax, or LTT, has different rate tables for residential, higher-rate residential and non-residential property. Before working out the tax, identify the category.
Most people think a purchase of homes must always be residential. That is not always right. A single deal for six or more homes has a special rule.
Mixed-use property uses non-residential rates for a different reason. Such a purchase combines a home with something that is not residential property.
What the official source says
The Welsh Revenue Authority says that a buyer who gets a major interest in six or more homes in one transaction can use non-residential rates. For that transaction, the legislation classifies those homes as non-residential.
Guidance also explains an alternative route: the buyer may claim the relief for buying more than one home at once, known as multiple homes relief. On that route, the relief rules calculate the homes. Legal conditions may trigger the higher residential rates.
- Non-residential rates can apply to a single purchase of six or more homes.
- A claim for multiple homes relief can provide an alternative calculation route.
- A farm, or a shop with a flat above it, may count as mixed-use property.
- A mixed-use purchase uses non-residential rates for the transaction.
There is one important limit. Non-residential treatment for this purchase does not turn the homes into non-residential property for every future LTT question.
What this means in practice
You should not start by assuming that a portfolio purchase follows the same LTT route as one house. First check how many homes are in the same transaction.
Then check whether the deal includes business property, farmland used for a business, a shop, or other non-residential land. One non-residential element can change the category of the whole transaction.
- Count the homes included in the same deal.
- Check whether all parts of the property are residential.
- Consider both the non-residential route and multiple homes relief for a six-home purchase.
- Do not treat the label used in the LTT calculation as a permanent label for the homes.
This is the part people can miss. A tax result for one purchase may affect neither the nature of the homes nor the answer on a later purchase.
How to analyse it
Work through the facts in order. The contract and plan matter more than the estate agent’s description.
- Is the land in Wales and part of one LTT transaction?
- Does the purchase include six or more homes?
- Does it include a shop, business premises, farm land or other non-residential property?
- If there are six or more homes, can the buyer claim multiple homes relief?
- When the buyer claims relief, do the higher residential rate conditions apply?
- For a later purchase, what homes do you actually hold at that time?
Where a buyer claims multiple homes relief for a mixed purchase, the law requires a just and reasonable split between the amount paid for the homes and the amount paid for other property. That split needs a sound factual basis.
Example
Amir buys a single block containing six flats under one contract. The special six-home rule means the purchase can be treated as non-residential for LTT. He can instead consider claiming multiple homes relief. That claim uses the relief calculation for the flats, and the higher residential rates may matter if their conditions are met.
Later, Amir buys another flat. The earlier tax treatment does not mean his six existing flats stop counting as homes when the facts for the later purchase are considered.
Why this can be difficult in practice
What actually decides a mixed-use case? Not what the seller calls it. The question is whether the transaction includes property that is not residential.
A farm is a common hard case. The farmhouse may be residential, while fields, buildings or business areas may not be. The documents, use of the land and the property bought all matter.
- A flat above a shop does not usually make the whole deal purely residential.
- Buying six homes through separate transactions is not the same as buying them in one transaction.
- Multiple homes relief is not automatic: it must be claimed.
- The correct rate table alone does not answer every later higher-rate question.
Official guidance gives the Welsh Revenue Authority’s view of how the rules work. The legislation is the law, and the rate bands must be checked for the transaction date.
Key takeaways
- Six or more homes in one deal can use non-residential LTT treatment.
- Mixed-use property is taxed at non-residential rates.
- A prior tax category does not change what counts as a home later.

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
- Whether a building is a home, or whether land is part of its garden or grounds, can depend on the facts.
- The source gives broad mixed-use examples but does not settle difficult boundary questions for particular farms, businesses or land.
- The skill bundle did not contain the requested currency-notice.md, so its stated currency date could not be checked.
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, transfer and plan showing everything bought together.
- Details of each home and any shop, farm, business premises or other land.
- A clear record of whether multiple homes relief is claimed.
- A just and reasonable split of the amount paid between homes and other property where relief is claimed.
