Which home is your main residence for higher LTT?
Main residence and higher LTT
You cannot nominate a main residence for LTT. The answer depends on the facts of how you live.
- A holiday home can be used regularly without becoming your main home.
- Time spent at each property is relevant but not decisive.
- The official example treats the Cardiff family home as the main residence.

Which home is your main residence for higher LTT?
If you own a holiday home as well as the home you live in, you cannot simply pick which one is your main residence for Land Transaction Tax.
This can matter when buying another property and working out whether higher LTT rates apply. LTT is Wales’s property tax, often called stamp duty.
What this rule is about
The higher LTT rules can apply when, at the time you buy a home, you own another one and are not replacing the home you live in. That exception matters.
That makes one question very important: which property is really your main home? It is not a matter of personal choice.
What the official source says
The Welsh Government’s technical guidance gives an example of a person with homes in Cardiff and Criccieth.
Although they live in Cardiff during the week with their family, they use the Criccieth property as a holiday home on many weekends and for several weeks each year. The distinction matters.
- On those facts, the Cardiff home is their main residence.
- You cannot nominate one of two homes as your main residence for LTT.
- Usually, the home where you spend most time will be your main residence.
- Time alone does not settle the question.
What this means in practice
Even when it is used on many weekends and for several weeks each year, a holiday home does not become your main home simply through frequent use. The wider picture matters: which home is the centre of your everyday life?
This is the part people get wrong.
Although a simple count of nights may point in one direction, it cannot answer the question by itself when the broader pattern of everyday life points elsewhere. It is not the whole answer.
- Living in one place with your family may be strong evidence.
- Regular weekday use may matter more than holiday visits.
- Calling a property your main home does not decide it.
- Keeping clear records can help explain the real position.
How to analyse it
Begin by considering how you actually live across both properties, including your working week, family life and the purpose of your stays. Do this rather than considering the address you would prefer to use.
Ask which property has the stronger claim to be your main home.
- Where do you normally live during the working week?
- Where does your family normally live?
- Is the other property mainly for holidays or short breaks?
- How often do you stay at each property?
- What is the purpose of each stay?
Example
Sam lives in Cardiff from Monday to Friday with their family.
Sam also owns a home in Criccieth, which the family uses for many weekends and several weeks each year while treating it as a holiday home.
On the facts in the official example, Cardiff is Sam’s main residence. Criccieth is a holiday home, even though it is used regularly.
Why this can be difficult in practice
Some arrangements are less clear than the official example. For instance, a person may split work, family life and overnight stays more evenly between two places.
There is no LTT form that lets them choose the answer.
- More nights at one home do not automatically decide the issue.
- A holiday home may be used frequently.
- The facts at the relevant time matter.
Key takeaways
- You cannot choose which of two homes is your main residence.
- Your actual pattern of life matters more than the label you use.
- Time spent at each home is important, but not conclusive.

Where this is not settled
- The legislation uses the term ‘only or main residence’ but does not set out a complete checklist for choosing between two homes.
- Deciding which home is more important is fact-sensitive.
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.
- Where you live during the working week
- Where your family lives
