Property-investment partnership SDLT election: using market value
In brief
A qualifying property-investment partnership can elect to use full market value when land moves into it, instead of the normal share-based SDLT calculation.
- The election must be put in the SDLT return or an amendment.
- It cannot be withdrawn once made.
- Its effect on later partner changes depends on whether they are Type A or Type B.

Property-investment partnership SDLT election: using market value
Property-investment partnership SDLT election: using market value
If land moves into a property-investment partnership, an SDLT election may replace the normal partnership calculation with the land’s full market value. That can change the stamp duty result at once. It can also change how the land is treated when partnership shares move later.
What this rule is about
When land moves between a partner and the partnership, rather than being sold in an ordinary transaction to a stranger, the special SDLT rules recognise the difference. They recognise the difference.
Usually, the value used for tax when land moves into a partnership depends on the partners’ shares. Instead, the rule asks how much of the land’s value has, in effect, moved to other people.
A different route applies for a property-investment partnership. This is a partnership whose sole or main activity is investing in, or dealing in, land.
This election is not a free tax break. It swaps the normal share-based calculation for the full market value of the land transferred. That may produce more tax, less tax, or simply a clearer result.
What the official source says
HMRC’s manual explains that a qualifying property-investment partnership can elect not to use the normal rule for a transfer of land into the partnership. Eligibility under the legislation arises only where the transfer first falls within the normal rule.
Once made, the election requires SDLT to use the market value of the land interest transferred, rather than the normal partnership calculation that would otherwise apply. It is final. You cannot later amend the return to remove it.
- The transfer must be one covered by the rule for land moving into a partnership.
- The partnership must be a property-investment partnership at the relevant time.
- The person treated as the buyer for SDLT must make the election.
- The election must be in the SDLT return or an amendment to it.
- The normal rule for property leaving a partnership is also switched off where relevant.
- The amount used for SDLT becomes the land’s full market value.
HMRC’s manual says the election should be made by letter to its Technical & Guidance Team. That is HMRC’s administrative guidance. Paragraph 12A itself requires inclusion in the return or an amendment; it does not state that a letter is a legal condition.
What this means in practice
Your key choice is not simply whether the election lowers tax today. It is whether using full market value now gives the right result for the whole arrangement, including later changes between the partners.
Although the election is made for the first transfer, it can have a lasting effect on some later transfers of partnership interests when the statutory facts bring those transfers within the relevant rules. Its effect lasts. It is not just a box ticked for the first transfer.
- Work out the normal share-based result before choosing the election.
- Obtain a proper market valuation before treating full value as the answer.
- Record why the partnership’s main activity meets the statutory test.
- Keep the election and return with the partnership’s permanent tax records.
If the election is added by amending the original return, it counts as made on the date of that original return. A later return may also be amended if it concerns an affected transaction and is still within its own amendment period.
How to analyse it
Start with the land transfer itself. Do not begin with the label given to the partnership. What matters is the documents, ownership and changes in shares.
- Did land move into the partnership from a partner, a new partner, or a connected person?
- Does that transfer fall within the normal partnership rule?
- Was the partnership’s sole or main activity investing in or dealing in land?
- What is the land’s market value on the relevant date?
- What result follows under the normal share-based calculation?
- What result follows if market value replaces that calculation?
- Have later partnership-share transfers happened, or are they planned?
- For each later transfer, is it Type A or Type B under the legislation?
Why does the Type A or Type B label matter? For a Type B transfer, land covered by this election does not count as relevant partnership property. In simple terms, it is left out of the land pool used for that later rule.
For a Type A transfer, the election alone does not stop the land being counted. Consequently, the same election can have different later effects, depending on the form of the partner change.
Example
Here is an illustration. Aisha owns land worth £1,000,000 and transfers it into a partnership that mainly holds investment land. After the transfer, Aisha has a 60% share and another partner has a 40% share.
Under the normal rule, the tax value depends on the statutory share calculation. Assume that calculation produces 60% of the market value: £600,000. If a valid election is made, the value used instead is the full market value: £1,000,000.
That does not tell you the tax bill. SDLT rates and other facts still matter. Even though those further matters determine the tax bill, the election changes the value being taxed by £400,000 in this example. The choice is clear.
Later, a transfer of a partnership share may need a separate SDLT review. If it is a Type B transfer, the land that was the subject of Aisha’s election is not included as relevant partnership property. A Type A transfer does not get that exclusion merely because she made the election.
Why this can be difficult in practice
It is tempting to treat this as a simple market-value election. It is not. The answer can turn on the exact ownership before and after the transfer, as well as later arrangements between the partners.
You might think a partnership that owns a few properties must qualify. It may not. The statutory question is whether investing in or dealing in land is its sole or main activity.
- A partnership agreement may not match the shares used in practice.
- Connected people can bring a transfer within the normal rule unexpectedly.
- A valuation needs to reflect the actual land interest transferred.
- A later change in partnership shares may have a different result from the original land transfer.
- Calling a later transfer Type A or Type B without checking the statutory facts can lead to the wrong answer.
- Once made, the election cannot be undone through an amended return.
Timing matters too. Under the general SDLT rule, a return amendment is allowed only for a limited period, normally no more than twelve months after the filing deadline unless another provision says otherwise. Nor does the special rule for affected later returns extend that later return’s own amendment period.
Key takeaways
- This election is available only to a qualifying property-investment partnership.
- It replaces the normal partnership calculation with full market value.
- It is final and can affect later changes in partnership shares.

Official guidance
The pages below are HMRC’s guidance. Guidance is not law. It sets out how HMRC 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. HMRC can also change or withdraw guidance, and it may not cover your facts.
Where this is not settled
- Whether the partnership’s sole or main activity is investing or dealing in land depends on its real activities and supporting records.
- Market value and the partners’ shares may need careful evidence, especially where connected people, trusts, or several assets are involved.
- HMRC’s suggested letter process is guidance, not a statutory condition for a valid election.
- The supplied legislation is verified only through 17 November 2025. Current law and any transaction after that date need checking against the official legislation.
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 partnership agreement and records of each partner’s share before and after the transfer.
- Documents showing why the transfer falls within paragraph 10.
- Evidence of the partnership’s sole or main business activity.
- A supportable market valuation of the land interest transferred.
- The original SDLT return, any amendment, and the text of the election.
- Records of later changes in partnership shares and their dates.
