Buying a home when you are a business partner: higher LTT rates
Partnership homes and higher LTT rates
A business partner buying a home personally may be able to disregard homes held by the partnership for its trading business. This does not usually extend to homes held for a property-letting business.
- Business partners are different from spouses or civil partners.
- The purpose of the partnership-owned home is crucial.
- A partnership purchase can depend on the home interests of its partners.

Buying a home when you are a business partner: higher LTT rates
Buying a home when you are a business partner: higher LTT rates
Being a business partner does not always mean that every home owned by the partnership counts as your own when you buy a home personally. That can matter when working out whether Wales’s higher Land Transaction Tax rates apply. LTT is the Welsh version of stamp duty on property purchases.
What this rule is about
Partnerships can own land and homes. Normally, LTT treats partnership property as held by the partners. Partners may seem to own another home.
Schedule 5 has a special rule for this situation. It can prevent a partnership-held home from counting against a partner who buys outside the partnership.
Here, “partner” excludes spouses and cohabitants. It means a member of a business partnership.
What the official source says
The law covers a partner who buys an interest in one or more homes, alone or with other people, but does not buy it for the partnership. Tax officials ignore partnership trade homes.
- The buyer must be a partner in a business partnership.
- The home being bought must not be for the partnership.
- The partnership-held home must be held for a trade run by that partnership.
- The rule applies when checking whether the buyer has another relevant home.
- It can apply to a purchase of one home or several homes.
- The usual higher-rate conditions and exceptions still need checking.
The official technical guidance gives a useful contrast. A partnership that develops property may hold homes for its trade. A farming business may also hold homes for its trade.
By contrast, the guidance does not treat a home held through a partnership for a property-letting business as used in a trade for this rule. Officials may count the partner’s share.
What this means in practice
The key issue is not simply whether a partnership owns a home. You need to ask why it owns it and what the partnership does with it.
If the home is genuinely part of the partnership’s trading business, it may be left out of the check for a partner’s personal purchase. Official guidance includes interests in letting businesses.
- A property developer’s trading stock may be ignored for this purpose.
- A home held for a farming trade may be ignored for this purpose.
- A rental property held through a partnership may still count for a partner.
- Calling an activity a trade does not settle the point.
- The purpose for which the home is held matters.
- The position at the relevant time of the purchase matters.
There is a second point that people can miss. When a partnership buys a home, LTT generally treats the partners as making that purchase. Partners’ homes can affect partnership LTT rates.
How to analyse it
Start with the purchase itself. Then separate the partnership’s property from the partner’s own property and identify the reason for each holding.
- Is the buyer a member of a business partnership?
- Is the buyer purchasing personally, rather than for that partnership?
- What other homes does the partnership hold?
- Which of those homes are held for a trade run by the partnership?
- Is any home instead used in a property-letting business?
- What share does the partner have in homes that are not ignored?
- Does the purchase meet the other conditions for the higher LTT rates?
- Does an exception, such as replacing the home you live in, apply?
Keep documents that show the business purpose. Documents can explain the position. Keep the partnership agreement, accounts, property records and evidence of the partnership’s activities.
Example
Rhys is a partner in a property development business. The business holds a house as part of a development project. Rhys buys a flat to live in, using his own money and not for the business. When checking whether he has another home for the higher LTT rates, the development house is ignored if it is held for the partnership’s trade.
Change one fact. If the partnership holds the house as a long-term rental property, the official guidance says Rhys’s interest in it is not ignored. It may then affect the higher-rate result for the flat.
Why this can be difficult in practice
The difficult question is often whether the partnership really holds a home for a trade. A business can own property for more than one reason, and labels in accounts or informal descriptions may not tell the full story.
This distinction can have a large tax effect. Personal purchases can obscure such partnerships. This includes family businesses and investment partnerships.
- Do not confuse business partners with a spouse or civil partner.
- Do not assume all partnership-owned homes are ignored.
- Do not assume a property-letting business is a trade for this rule.
- Check whether the new home is bought personally or for the partnership.
- Check every partner’s relevant home interests when the partnership is the buyer.
Key takeaways
- A partner’s personal home purchase may be treated differently from partnership property.
- Homes held for a partnership trade can be ignored in the higher-rate check.
- Property held for a letting business may still count against the partner.

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 partnership’s activity is a trade can depend on the facts. The source specifically distinguishes property letting from a trade, but other activities may need careful classification.
- Ownership arrangements, the partnership agreement and the purpose for which each property is held may affect the answer.
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 and completion details for the home being bought
- The partnership agreement and current list of partners
- Land Registry records or equivalent evidence for partnership-held homes
- Evidence of the partnership’s business and the purpose of each home
- Details of any letting activity, development activity or other trade
- The value and ownership share of other homes held by each partner
