Partnership Property Transfer: SDLT Provisions and Lower Proportion Calculation Example

SDLT on Partnership Property Transferred to a Partner

When a partnership transfers land or property to one of its partners, SDLT may apply only to part of the market value rather than the whole amount. The key calculation is the “sum of the lower proportions”, which can reduce the charge where the transferee and any connected partners already had an economic interest in the property through the partnership.

• In HMRC’s example, partners D, E and F share partnership profits 30%, 30% and 40% respectively, and the property is transferred to D.
• D is connected with E because they are married, so both D and E count as corresponding partners, but F does not because F is not connected with D.
• After the transfer, D owns 100% of the property, and HMRC’s example apportions that 100% equally between D and E at 50% each for the calculation.
• For each corresponding partner, you compare the apportioned property share with that partner’s partnership share and take the lower figure: 30% for D and 30% for E.
• The sum of the lower proportions is 60%, so only the remaining 40% of the property’s market value is chargeable to SDLT.
• In practice, the result depends on whether the partnership transfer rule applies, who is connected, the correct partnership shares, and how the statutory apportionment is made.

SDLT on a transfer of partnership property to a partner: how the “sum of the lower proportions” works

This page explains an HMRC example on a technical SDLT rule that applies when land held by a partnership is transferred to a partner. The example shows how to work out what proportion of the property’s market value is chargeable when connected partners are involved. The point matters because the tax charge is not always based on the full market value. Instead, the legislation can reduce the charge by reference to the partners’ existing economic interests.

What this rule is about

Schedule 15 to Finance Act 2003 contains special SDLT rules for partnerships. One of those rules applies where a partnership transfers a chargeable interest, such as a freehold property, to a partner.

In broad terms, the legislation looks at how much of the property is, in substance, moving out of the partnership and into the hands of someone who already had an economic stake in it through the partnership. To measure that, the legislation uses a calculation called the “sum of the lower proportions”. That figure reduces the part of the market value that is charged to SDLT.

This HMRC example deals with a situation where the receiving partner is connected with one of the other partners, but not with all of them. That matters because connected partners can be treated as “corresponding partners” in the calculation.

What the official source says

The source example assumes:

• a partnership owns a chargeable interest;
• the property is transferred to partner D;
• there are three partners: D, E and F;
• D is married to E, so D and E are connected for SDLT purposes;
• D is not connected with F;
• D and E each have a 30% share of the partnership income profits, and F has 40%.

HMRC then applies the statutory steps for finding the “sum of the lower proportions”:

• D is a relevant owner because, after the transfer, D owns the property and, before the transfer, D was a partner.
• D is a corresponding partner in relation to himself.
• E is also a corresponding partner in relation to D because E was a partner immediately before the transfer and was connected with D.
• D owns 100% of the property after the transfer.
• That 100% is apportioned between D and E. HMRC’s example apportions it 50% to D and 50% to E.
• For each corresponding partner, you then take the lower of:

• the proportion of the chargeable interest attributed to that partner in the apportionment, and
• that partner’s partnership share.

On HMRC’s figures:

• D: lower of 50% and 30% = 30%
• E: lower of 50% and 30% = 30%

The sum of the lower proportions is therefore 60%.

HMRC concludes that 40% of the market value is chargeable, because the chargeable proportion is 100% minus 60%.

What this means in practice

The practical effect is that SDLT is charged only on the part of the property value that represents an interest moving beyond the existing economic interests of the relevant partner and connected partners.

In this example, D already had a 30% partnership profit share, and D’s spouse E had another 30%. Because E is connected with D, E’s share is brought into the calculation. Together, that allows 60% of the market value to be left out of charge. The remaining 40% reflects F’s stake, because F is neither the transferee nor connected with the transferee.

So the example is really showing this idea: where partnership property is transferred to a partner, SDLT is aimed at the part of the value that is effectively being acquired from partners outside the transferee’s own and connected persons’ existing interests.

How to analyse it

If you are dealing with a transfer of land from a partnership to a partner, a sensible way to approach this example is as follows.

1. Identify whether the partnership transfer rule is engaged

The example assumes that paragraph 18 of Schedule 15 applies. So the starting point is whether the transaction is one to which that paragraph applies.

2. Identify the relevant owner

You look for the person who, immediately after the transaction, is entitled to a proportion of the property and who was a partner immediately before it. In the example, that is D.

3. Identify the corresponding partners

This includes:

• the relevant owner, if that person was a partner immediately before the transaction; and
• any partner who was a partner immediately before the transaction and was connected with the relevant owner.

In the example, D and E are included. F is not, because F is not connected with D.

4. Work out the post-transaction property entitlement

Here, D owns 100% of the property after the transfer.

5. Apportion that entitlement among the corresponding partners

The example allocates the 100% equally between D and E, giving 50% each. The source does not explain in detail why that apportionment is chosen in this example, but it uses that split to demonstrate the next step.

6. For each corresponding partner, compare two figures

For each corresponding partner, compare:

• the proportion of the property attributed to that partner under the apportionment; and
• that partner’s partnership share.

You take the lower figure for each person.

7. Add the lower figures together

That total is the “sum of the lower proportions”.

8. Find the chargeable proportion of market value

Subtract the sum of the lower proportions from 100%. The balance is the proportion of the market value that is chargeable.

Example

Illustration based on the HMRC example:

• D, E and F are partners.
• D and E each have a 30% profit share. F has 40%.
• The partnership transfers a property to D.
• D is connected with E, but not with F.
• After the transfer, D owns 100% of the property.
• That 100% is apportioned 50% to D and 50% to E.
• D’s lower proportion is 30% because that is lower than 50%.
• E’s lower proportion is 30% because that is lower than 50%.
• The total is 60%.
• So 40% of the property’s market value is chargeable to SDLT.

Seen another way, the calculation leaves out the part of the value that corresponds to D and E’s existing partnership interests, and charges the balance.

Why this can be difficult in practice

The legislation is highly mechanical, but applying it can still be difficult.

One issue is identifying who is connected with whom. In this example, the connection arises because D and E are married. In real cases, the connected persons rules can be wider and need careful checking.

Another issue is the apportionment in step three. HMRC’s example simply chooses a 50/50 split between D and E. The source does not expand on how apportionment choices should be made in more complex cases, so readers should be careful not to assume that every case involving two corresponding partners will automatically be split equally.

A further point is that the example uses partnership income profit shares as the relevant partnership shares. In practice, the correct partnership share for Schedule 15 purposes must be identified accurately from the facts and the legislation.

Finally, this is only one part of the wider partnership code. The example assumes that paragraph 18 applies and focuses only on the lower proportions calculation. In a real transaction, the earlier question is whether the transaction falls within that rule at all.

Key takeaways

• When partnership property is transferred to a partner, SDLT may be charged on only part of the market value rather than all of it.
• Connected partners can increase the “sum of the lower proportions” and therefore reduce the chargeable share of market value.
• The calculation is technical and depends on the exact partnership shares, the connected persons position, and the statutory apportionment exercise.
