LTT multiple dwellings relief: details WRA needs about the homes
If you are changing an LTT return or claiming a refund for multiple dwellings relief, WRA needs clear details of every home in the purchase. LTT is Wales’s property tax, not stamp duty land tax. Getting the number of homes wrong can change the result.
What this rule is about
The relief may apply to a purchase that includes at least two homes. A home that looks separate may still count with another home as one. This is why WRA asks about facilities and access.
What the official source says
WRA says that, when you seek relief for a transaction involving more than one part of a property, you will need information about the homes involved in the transaction. That information matters.
- State how many homes you are claiming relief for.
- Say whether any home is subsidiary to another.
- Describe the facilities in each home.
- Explain how each home can be accessed.
What this means in practice
Rather than relying only on an estate agent’s description or a label on a plan, set out the physical facts that show how each part functions. Labels alone do not decide it. For relief, the question is whether there are two homes, not merely two sets of rooms.
- Keep floor plans and sale details.
- Note kitchens, bathrooms and sleeping space.
- Record separate doors, paths and shared entrances.
How to analyse it
Start with what was bought on the transaction date. Then consider each part of the property in its real setting.
- How many homes are included in the purchase?
- What facilities does each part have?
- Can each part be reached separately?
- Is a smaller home within the grounds or building of another?
- Could that smaller home be subsidiary under the legal test?
Example
Alun buys a house with a self-contained flat above the garage. His claim says there are two homes. He provides the plan, describes the flat’s kitchen and bathroom, and explains its entrance. WRA may then consider whether the flat is a separate home or is subsidiary to the house.
Why this can be difficult in practice
A separate front door may seem conclusive. It is not. Shared access, limited facilities and the relationship between the buildings can all matter. The official source does not give a fixed facilities checklist.
- A locked internal door does not answer every question.
- A separate postcode may not answer every question.
- A small annex may be subsidiary to the main home.
Key takeaways
- Give WRA full details of every home in the purchase.
- Explain facilities and access with plans where available.
- Check carefully whether an annex is subsidiary.

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 part of a property is a separate home can depend on the full facts, including its facilities and how people can enter it.
- Whether a smaller home is subsidiary depends on the statutory test and the facts of the 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 number of homes included in the relief claim
- plans showing each home and its access
- details of kitchens, bathrooms and living facilities
- information showing whether one home is subsidiary to another
