Understanding Chargeable Consideration for Partnership Property Transfers Under Para18 Rules

SDLT on property transferred out of a partnership

When land or property is transferred out of a partnership, SDLT is not always based on the price actually paid. If paragraph 18(2) applies, the chargeable consideration is instead a percentage of the property’s market value, using the formula (100 – SLP)%, where SLP is worked out under paragraph 20.

• The rule is designed to avoid charging SDLT on the part of the property value that already reflects the transferee’s existing interest in the partnership.
• A high SLP reduces the amount charged to SDLT, while an SLP of 0 would bring the full market value into charge.
• SDLT can still arise even if little or no money is paid, including on retirement, reorganisation, dissolution, or distribution of partnership assets.
• Property is treated as remaining partnership property after dissolution until it is actually distributed, so the rule can still apply at that stage.
• Extra rules may affect the result, including paragraph 24 for all-corporate partnerships, paragraph 23 for transfers between partnerships, and any election under paragraph 12A.
• In practice, the most important step is usually calculating the SLP correctly, as this determines how much of the market value is treated as chargeable consideration.

SDLT when property is transferred out of a partnership: how paragraph 18(2) works

This page explains how Stamp Duty Land Tax can apply when land or property is transferred from a partnership to a person connected with that partnership, such as a partner. The rule is unusual because the taxable consideration is not simply whatever money changes hands. Instead, the legislation can substitute a proportion of the property’s market value.

What this rule is about

Partnership property has special SDLT rules. When property moves into or out of a partnership, the normal SDLT approach based on the price paid may not give the intended result. Paragraph 18 is one of the rules designed to deal with transfers out of a partnership.

The key idea is that a person should not normally be charged SDLT on the part of the property value that already reflects their existing economic interest in the partnership. The legislation therefore uses a formula. It taxes only a proportion of the market value, rather than automatically taxing the whole value.

The proportion taxed depends on the “sum of the lower proportions”, usually shortened to SLP. The source material does not set out the detailed SLP calculation itself, but says that it is worked out using the steps in paragraph 20.

What the official source says

The HMRC manual says that where paragraph 18 applies to the transfer of a chargeable interest from a partnership, the chargeable consideration is calculated as a proportion of the market value of the interest transferred.

That proportion is:

(100 – SLP)% of the market value

So the starting point is the market value of the property interest being transferred. You then reduce that value by the SLP percentage. The remaining percentage is the amount treated as chargeable consideration for SDLT purposes.

The manual also highlights four important qualifications:

• SLP is calculated under paragraph 20.
• If the transfer is from a partnership made up entirely of companies, paragraph 24 may also need to be considered.
• If property is transferred out of one partnership and into another, and both paragraph 18 and paragraph 10 could apply, paragraph 23 determines how the rules interact.
• Paragraph 18 can also apply when a partnership ends and its assets are distributed to the former partners.

The manual adds that, for this purpose, property that was partnership property before dissolution is treated as remaining partnership property until it is actually distributed. It also says that the rule is subject to any election under paragraph 12A.

What this means in practice

The practical effect is that SDLT on a transfer out of a partnership may arise even if little or no money is paid. That is because the legislation may substitute deemed consideration based on market value.

At the same time, the whole market value is not always taxed. The formula recognises that the transferee may already have had an indirect stake in the property through their partnership interest. The SLP mechanism is intended to measure that and reduce the taxable amount accordingly.

In broad terms:

• if the SLP is high, the taxable proportion is lower;
• if the SLP is low, more of the market value is brought into charge;
• if the SLP were 100, the formula would produce no chargeable consideration under this rule;
• if the SLP were 0, the whole market value would be charged.

This means the SDLT result may differ sharply from what the parties think they have done commercially. A transfer on retirement, reorganisation, or breakup of a partnership can still trigger SDLT even where the parties view it as simply sorting out existing ownership.

How to analyse it

A sensible way to approach the issue is to ask the following questions.

• Is there a transfer of a chargeable interest in land?
• Is the transfer being made from a partnership?
• Does paragraph 18 apply to this type of transfer out?
• What is the market value of the chargeable interest transferred?
• What is the SLP, calculated under paragraph 20?
• Applying the formula, what percentage of market value becomes chargeable consideration?
• Is the partnership made up wholly of bodies corporate, so that paragraph 24 may modify the result?
• Is the property moving from one partnership to another, so that paragraph 23 may govern the interaction with paragraph 10?
• Has the partnership dissolved, and if so, has the property actually been distributed yet?
• Is there any relevant election under paragraph 12A that affects the position?

The critical factual and computational step is usually the SLP calculation. The manual page provided does not explain that calculation in detail, but it makes clear that paragraph 20 supplies the method and that the SDLT charge under paragraph 18 depends on it.

Example

This is only an illustration of the formula, not a statement of any particular taxpayer’s position.

A partnership transfers a property to one of its partners. The market value of the property interest transferred is £800,000. After applying the paragraph 20 steps, the SLP is calculated at 60.

The chargeable consideration under paragraph 18(2) is:

(100 – 60)% of £800,000 = 40% of £800,000 = £320,000.

So, for SDLT purposes, the partner is treated as giving chargeable consideration of £320,000, even if the cash actually paid is different or nil.

Why this can be difficult in practice

Partnership SDLT rules are technical and highly fact-sensitive. The main difficulty is that the taxable amount is driven by a statutory formula rather than by the transaction documents alone.

Several points can complicate the analysis:

• The SLP calculation may be intricate, especially where partnership interests have changed over time.
• A transfer on dissolution may look like a simple distribution of assets, but the legislation treats the property as remaining partnership property until distribution, so paragraph 18 can still apply at that stage.
• Where corporate partners are involved, paragraph 24 may alter the position.
• Where land moves from one partnership to another, more than one special rule may appear relevant, and paragraph 23 is then needed to determine the correct treatment.
• An election under paragraph 12A may affect whether this paragraph applies in the usual way.

Because of those interactions, it is not safe to assume that a transfer out of a partnership is SDLT-free just because the recipient was already a partner or because the transfer happens as part of winding up the partnership.

Key takeaways

• When paragraph 18 applies, SDLT is charged on a percentage of market value, not simply on the price paid.
• The percentage charged is (100 – SLP)%, and SLP is calculated under paragraph 20.
• Special additional rules may apply for all-corporate partnerships, transfers between partnerships, partnership dissolutions, and paragraph 12A elections.
