Guide on SDLT Provisions for Property Transfers to Partnerships with Connected Partners

SDLT on Putting Property into a Partnership with a Connected Partner

When property is transferred into a partnership, SDLT is not always charged on the full market value or on the share the transferor appears to have given up. If one of the partners is connected to the transferor, such as a spouse, their partnership shares may be grouped together. In HMRC’s example, this means SDLT is charged on 40% of the property’s market value, reflecting the share of the unconnected partner.

• Special SDLT rules apply when a property is transferred into a partnership, using a formula rather than automatically taxing the whole market value.
• If the transferor is connected with another partner, their shares may be aggregated for the SDLT calculation.
• In HMRC’s example, D and D’s spouse E each hold 30% of partnership profits, while unconnected partner F holds 40%.
• Although D appears to have given up 70% of the property, SDLT treats D and E together, so only F’s 40% share is chargeable.
• The calculation is based on HMRC’s “sum of the lower proportions” method, which gives a result of 60 and leaves 40% of market value as chargeable consideration.
• Whether someone is “connected” is a legal test for SDLT purposes, so the exact relationship between the parties must be checked carefully.

SDLT on transferring property into a partnership where one partner is connected to the transferor

This page explains how SDLT can apply when a person transfers property into a partnership that includes both unconnected partners and a connected partner, such as a spouse. The point matters because the connected person’s partnership share is not always treated in the same way as an unconnected person’s share. That can change how much of the property’s market value is treated as chargeable consideration.

What this rule is about

Special SDLT rules apply when a chargeable interest, such as a freehold property, is transferred to a partnership. These rules are designed to work out how much value has really moved from the transferor to the other partners.

In broad terms, if you transfer property into a partnership of which you are already a member, SDLT is not automatically charged on the whole market value. Instead, the legislation uses a formula. That formula looks at the partners’ shares in the partnership and, importantly, whether any of the partners are connected with the transferor.

The source material deals with a specific situation: the transferor is a partner, one of the other partners is the transferor’s spouse, and the third partner is not connected. The spouse’s share is aggregated with the transferor’s share when applying the calculation.

What the official source says

HMRC’s example starts with individual D transferring a freehold property to a partnership made up of D, E and F.

• D has a 30% share of partnership income profits.
• E also has 30%.
• F has 40%.

D is connected with E because they are married, but not connected with F.

Looking only at economic shares, D has given up 70% of the property by transferring it into the partnership, because D’s own partnership share is only 30%. However, the SDLT calculation does not stop there. Because D and E are connected, their shares are effectively treated together for this purpose.

HMRC says that D and E are treated as if they were a single partner, with their shares aggregated. On the facts given, this produces a “sum of the lower proportions” of 60. The result is that the chargeable consideration is 40% of the market value of the property, calculated as 100 minus 60.

HMRC also explains the practical effect of that result: the 40% chargeable proportion matches the part of the property effectively acquired, through the partnership, by the unconnected partner F.

What this means in practice

The key practical point is that a transfer into a partnership is not analysed simply by asking how much of the property the transferor no longer owns economically. Connected partners can change the result.

Here, D may appear to have given up 70% of the property, because D’s own partnership entitlement is only 30%. But SDLT does not treat the spouse’s 30% share as if it had passed to a wholly separate person. Instead, D and E are grouped together for this part of the calculation.

That means only the part effectively passing outside that connected grouping is brought into charge under the formula used in HMRC’s example. On these facts, that is the 40% attributable to F, the unconnected partner.

So the practical outcome is that SDLT is charged by reference to 40% of market value, not 70% and not 100%.

How to analyse it

When looking at a transfer of property into a partnership, ask these questions in order:

• Who is transferring the property?
• Who are the partners immediately relevant to the transaction?
• What are the partners’ profit-sharing proportions?
• Is any partner connected with the transferor for SDLT purposes?
• If so, do those connected partners’ shares need to be aggregated under the partnership rules?
• After applying that aggregation, what proportion is treated as remaining within the transferor and connected persons, and what proportion is treated as passing to unconnected partners?

In the example, that process leads to this practical conclusion:

• D’s own share is 30%.
• E’s share is 30%.
• Because D and E are connected, those shares are treated together.
• That leaves the 40% share of F, who is unconnected.
• The SDLT charge is therefore based on 40% of market value.

The detailed statutory computation is expressed by HMRC as the “sum of the lower proportions”. The source gives the result of that computation as 60, leading to chargeable consideration of 40% of market value.

Example

Illustration: A husband owns a freehold building personally and transfers it into a trading partnership. He is entitled to 30% of partnership profits, his wife is entitled to 30%, and a third partner is entitled to 40%.

At first glance, it may look as though he has given away 70% of the building, because he now only has a 30% partnership interest. But for SDLT purposes, the wife’s 30% is not treated in the same way as the third partner’s 40%, because she is connected with him.

Using HMRC’s approach in this example, the chargeable consideration is 40% of the property’s market value. That reflects the part effectively acquired by the unconnected partner.

Why this can be difficult in practice

The difficulty is that the economic picture and the SDLT picture are not always the same. A person may think they have given up a large share of a property by moving it into a partnership, but the SDLT rules can reduce the chargeable amount where connected partners are involved.

The source material is also only an example. It gives the result of the computation and the reason for it, but not the full legal mechanics on the page itself. To apply the rule properly, you need to identify the relevant connected persons and the correct partnership shares, and then apply the statutory formula as reflected in HMRC’s linked calculation.

Another practical difficulty is that “connected” is a legal concept, not just an everyday idea of family relationship. In this example, marriage is enough to make D and E connected for SDLT purposes. In other cases, whether parties are connected may require closer analysis under the legislation.

Key takeaways

• When property is transferred into a partnership, SDLT is not necessarily charged on the whole market value.
• If the transferor is connected with another partner, their partnership shares may be aggregated in the calculation.
• In HMRC’s example, that means SDLT is charged by reference to the 40% share held by the unconnected partner, not the 70% apparently given up by the transferor alone.
