Understanding SDLT Higher Rates for Partnerships and Additional Dwellings

When a partner’s existing property interest can be ignored for SDLT higher rates

A limited SDLT rule can let an individual partner ignore an existing interest in a dwelling held through a trading partnership when buying a home personally. This only applies in narrow cases: the partnership must be carrying on a trade, the existing dwelling must be used for that trade, and the new purchase must not be for partnership purposes.

• The rule is aimed at Condition C of the higher rates test, which looks at whether the buyer already owns a major interest in another dwelling.
• A partner buying a dwelling personally may be able to ignore a partnership-held dwelling interest if the partnership is a genuine trading business and the dwelling is used in that trade.
• The exception does not apply if the new dwelling is being bought by or for the partnership.
• Property letting businesses and other businesses exploiting land for rent are not treated as a trade for this rule.
• Where a dwelling is bought by or for a partnership, all partners are treated as relevant purchasers, and if one partner triggers the higher rates, the whole purchase is charged at those rates.
• In practice, the difficult points are often factual, such as whether the purchase is really personal or for partnership purposes, and whether the existing dwelling is actually used in the partnership’s trade.

When a partner’s existing property interest can be ignored for the SDLT higher rates

This page explains a narrow exception within the higher rates for additional dwellings. In some cases, a person who is a partner in a trading partnership can ignore an existing interest in a dwelling held through that partnership when working out whether their own purchase triggers the higher SDLT rates. The exception is limited. It does not apply to every partnership, and it does not apply where the new purchase is for partnership purposes.

What this rule is about

Under the SDLT higher rates rules, one of the key questions is whether the buyer already has a major interest in another dwelling at the end of the effective date of the transaction. If they do, the purchase may fall within the higher rates regime, depending on the other conditions.

For partners, that question can be awkward. SDLT has special rules for partnerships, and a partner can be treated as having an interest in land bought by or for the partnership. Without a special rule, that could mean a partner is treated as already owning a dwelling even where the property is really part of the partnership business rather than part of the partner’s personal property portfolio.

Paragraph 14 of Schedule 4ZA Finance Act 2003 provides a limited relaxation. It allows some partnership-held dwelling interests to be ignored for Condition C of the higher rates test.

What the official source says

The HMRC manual says that some major interests in dwellings held by a partner through a partnership can be ignored even though the interest is still owned at the end of the effective date.

This treatment can apply where:

• the buyer is an individual,
• the buyer is a partner in a partnership, and
• the buyer is purchasing a major interest in a dwelling other than for partnership purposes.

HMRC notes that this is most likely to arise where the individual is buying a home for themselves, such as a main residence.

The exception only applies if the partnership is carrying on a trade and the dwelling in which the purchaser already has an interest through the partnership is used for the purposes of that trade.

The manual also makes two important limits clear:

• a property letting business, or any business exploiting land for rent, carried on by a partnership is not a trade for this purpose;
• an interest in a dwelling held for the purposes of a partnership cannot be ignored when the new dwelling is itself being bought for partnership purposes.

Separately, the manual reminds readers that a partner is treated as a joint purchaser of land bought by or on behalf of a partnership under Schedule 15 Finance Act 2003. So if a dwelling is being acquired by or for the partnership, the higher rates tests must be considered for all partners. If any one partner would cause the higher rates to apply, the whole purchase is charged at the higher rates.

What this means in practice

The practical effect is that a partner is not automatically treated as owning an additional dwelling for higher rates purposes just because the partnership uses a dwelling in its trading business.

But the exception is much narrower than it may first appear.

You should separate two situations:

• an individual partner buying a dwelling personally, not for the partnership; and
• the partnership buying a dwelling, or a dwelling being bought for partnership purposes.

In the first situation, the partner may be able to ignore an existing interest in a partnership-used dwelling, but only if the partnership is carrying on a trade and the dwelling is used for that trade.

In the second situation, the exception does not help. If the purchase is for partnership purposes, a dwelling already held for partnership purposes cannot be ignored. In addition, because the partners are treated as joint purchasers, the higher rates position has to be checked across the partner group.

This matters particularly where a partnership owns or uses living accommodation connected with a trading business, for example accommodation genuinely used in the course of the trade. It matters less, and often not at all, where the partnership’s business is property rental, because HMRC states that this is not a trade for this rule.

How to analyse it

A sensible way to approach the issue is to ask these questions in order:

• Who is buying the dwelling? Is it an individual partner personally, or is it the partnership or a nominee for the partnership?
• Is the new purchase for partnership purposes? If yes, this exception will not allow partnership-held dwelling interests to be ignored.
• Does the buyer already have a major interest in another dwelling through the partnership?
• Is the partnership carrying on a trade? Do not assume that every business counts as a trade. HMRC expressly says a property letting business or other business exploiting land for rent is not a trade here.
• Is the existing dwelling used for the purposes of that trade?
• If the purchase is by or for the partnership, have you tested the higher rates position for every partner? If one partner brings the purchase within the higher rates, the whole purchase is charged at those rates.

The key points are purpose and character:

• the purpose of the new purchase, and
• the character of the partnership business and use of the existing dwelling.

Example

Illustration: A and B are partners in a trading partnership. The partnership uses a dwelling for the purposes of that trade. A wants to buy a house personally to live in, and the purchase is not for partnership purposes. In principle, paragraph 14 may allow A’s existing interest in the partnership-used dwelling to be ignored when considering Condition C for A’s personal purchase.

By contrast, if A and B are acquiring a dwelling for the partnership, the partnership-held dwelling interest cannot be ignored for that purchase. The higher rates analysis must then be applied across all partners, and if either A or B would cause the higher rates to apply, the whole partnership purchase is charged at the higher rates.

If instead the partnership business is simply letting property for rent, HMRC’s view is that this is not a trade for this rule, so the exception would not be available on that basis.

Why this can be difficult in practice

The hardest issues are usually factual rather than mechanical.

First, it may not be obvious whether the new purchase is truly personal or is in substance for partnership purposes. The legal documents, funding, accounting treatment, and intended use may all matter.

Second, the requirement that the partnership is carrying on a trade can be difficult at the edges. The manual is clear that property letting and exploiting land for rent do not count, but other activities may require closer analysis.

Third, the rule depends on the dwelling being used for the purposes of the partnership’s trade. That invites questions about the actual use of the property, not just who owns it.

Finally, partnership purchases create an all-partners problem. Even if most partners would not individually trigger the higher rates, one partner may be enough to bring the entire purchase within the higher rates charge.

Key takeaways

• A partner may be able to ignore an existing dwelling interest held through a partnership, but only for a personal purchase that is not for partnership purposes.
• The exception depends on the partnership carrying on a trade and the existing dwelling being used for that trade; property rental businesses do not count as a trade for this rule.
• Where a dwelling is bought by or for the partnership, all partners must be tested, and one partner can make the whole purchase liable to the higher rates.
