LTT: when does a property count as one home?
Whether a property amounts to one home can affect how land transaction tax, or LTT, applies in Wales when a residential building has more than one occupier. LTT is Wales’s version of stamp duty. The key question is not how many people live there. It is whether the residential property makes up one separate home.
What this rule is about
Some buildings are shared by several people. Others have separate living spaces behind one front door. That can make it unclear whether the building is one home or several.
The law describes a residential property as a “dwelling” where it comprises a single home, regardless of how many people occupy the building or live within it. The real facts decide, not a label in an advert, tenancy or council record.
What the official source says
Section 73 gives the basic legal definition. Welsh Government technical guidance then explains that private cooking and bathroom facilities are important when deciding the facts of a particular case.
- The property must be residential.
- It must comprise a single home.
- Private access to cooking facilities is an important factor.
- Private access to bathroom facilities is also an important factor.
- A shared house does not become several separate homes merely because several people live there, even if they occupy different rooms or have separate arrangements. That alone is not enough.
- Where occupiers do not have private kitchens and bathrooms, the guidance says the property will not be treated as several separate homes, even if they use separate rooms. That is the guidance’s approach.
What this means in practice
Do not count bedrooms, tenants or locks on doors and assume that each creates a separate home. Shared facilities can point strongly the other way.
This is the part people can miss. Even where a building produces separate rents for different occupiers, it may still remain one home for this purpose when its facilities are shared. Rents do not decide it.
- Check whether each living area has its own cooking facilities.
- Check whether each living area has its own bathroom facilities.
- Check whether those facilities are private, rather than shared.
- Use the building as it actually exists at the relevant time.
How to analyse it
Start with the building, not the paperwork. Ask what each occupier can use without sharing with other occupiers.
- Is the property residential?
- Is it arranged as one home or as separate homes?
- Does each claimed separate home have private cooking facilities?
- Does each claimed separate home have private bathroom facilities?
- Are those facilities available to all occupants, or shared between them?
Example
Amir buys a house occupied by four unrelated tenants. They each have a bedroom, but all use the same fitted kitchen and bathrooms. On the facts described in the official guidance, the house is not four separate homes because the occupants do not have private cooking and bathroom facilities.
Why this can be difficult in practice
Private facilities matter, but the law does not give a checklist that decides every case. A converted building may have some separate facilities but still have shared areas. Small layout differences can therefore matter.
- A bedroom with a kettle is not necessarily a private kitchen.
- A bathroom shared by two occupiers is not private to either one.
- Plans may not show how facilities are really used.
- The official guidance is helpful, but section 73 remains the legal starting point.
Key takeaways
- LTT looks at whether residential property comprises one home.
- The answer depends on the facts of the building.
- Private kitchens and bathrooms are especially important.

Legislation

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
- Section 73 does not set out a detailed list of features that always decide whether a property is one home.
- The answer can depend on the building’s actual layout and facilities.
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 and access arrangements
- Details of which facilities each occupier can use privately
- Information about how the property is arranged and occupied
