Multiple homes relief and LTT: when homes count separately
For multiple homes relief, every home included must function as a separate home. This may affect your Land Transaction Tax (LTT) bill. In Wales, LTT replaced stamp duty land tax in 2018.
What this rule is about
Multiple homes relief can apply where you buy two or more homes in the same transaction. The law says the purchase must include interests in at least two homes.
The rule requires separate homes rather than additional rooms. That difference may determine whether relief is available.
What the official source says
For a claim, each home should be capable of standing alone, with the guidance setting out practical indicators that must be assessed on the purchase date.
Those indicators cover facilities, access, privacy, and movement between the parts. Check them at that point.
- Each home should have somewhere to store, prepare and cook food.
- Each home should have a toilet, sink, and bath or shower.
- Each home should have space for living and sleeping.
- Each home should have its own independent way in.
- Each home should be private and secure.
- People should not move freely between the homes through a shared hallway.
- Any door linking the homes should lock on the purchase date.
What this means in practice
A self-contained annexe may count separately. Even a large bedroom suite may not count as a separate home when its layout or access falls short, whatever label appears in the sales details.
Labels do not decide the issue.
The official page also says that, alongside the question of multiple homes relief, you must consider whether the higher rates of LTT apply to the purchase.
Relief for buying more than one home does not remove that separate question.
- Check the layout before you send the LTT return.
- Look at the property as it stood when you bought it.
- Do not assume an annexe automatically counts as another home.
- Keep plans, photos and details of locks and entrances.
How to analyse it
Start with what you actually bought. Test each part of the property separately.
- List every home you want to include in the claim.
- Check whether each one has the facilities needed for day-to-day living.
- Trace how someone enters and moves around each part.
- Check whether a connecting door locked on the purchase date.
- Consider the higher rates of LTT as a separate step.
Example
Mair buys a house with an annexe. The annexe has its own kitchen, bathroom, sleeping area and outside entrance. A door connects it to the house, but the door locks.
On these facts, the Welsh Revenue Authority guidance points towards treating the annexe as a separate home, because it has its own facilities and outside entrance, and its door to the house locks.
That is the indicated treatment. Free movement through a shared hallway can change the answer.
Why this can be difficult in practice
This is where people often go wrong. An advert may describe a property as two homes.
Yet, when the layout is examined in detail, a property may lack the separate access or real privacy needed to support that description, despite the way the advertisement presents it.
Advertisements are not decisive.
The Act uses a general idea of a single home. The Welsh Revenue Authority’s list helps apply that idea, but it cannot resolve every unusual layout without considering its particular facts.
Facts still matter.
- A shared hallway can cause difficulty.
- A connecting door that does not lock can matter.
- Temporary kitchen or bathroom facilities may need closer checking.
- Plans may not show how people actually move through the property.
Key takeaways
- Each home in the claim should stand on its own.
- Privacy, access and lockable links matter.
- Check the higher rates of LTT separately.

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 does not say how much shared access or shared space is acceptable. Small differences in layout and how residents use the property can matter.
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.
- Floor plans showing kitchens, bathrooms, sleeping space and access routes
- Photographs and sale details showing the layout on the purchase date
- Details of any connecting doors and whether they lock
- Information needed to consider the higher rates of LTT
