Stamp duty when partners split up and take separate farms
Partnership farm splits and SDLT
When partners divide up farms held by their partnership, SDLT may be based on market value rather than only the balancing payment.
- HMRC’s 50:50 example produces a 50% market-value figure for each farm.
- The partners’ connection and share history can change the answer.
- The farms need reliable market valuations.

Stamp duty when partners split up and take separate farms
If a partnership splits and each partner takes a farm, HMRC may base stamp duty land tax on part of each farm’s market value rather than simply on the cash paid between them. Cash alone does not decide it. That can matter even where the payment is only meant to make the split fair.
What this rule is about
Special SDLT rules apply. They cover land leaving a partnership and going to a current or former partner.
The idea is to recognise the share that the person already had in the partnership property. Yet the rule does not automatically remove SDLT because a partner takes land on a break-up.
What determines the outcome? Consider the market value of the farm, the partners’ shares, and whether they are connected.
What the official source says
HMRC’s manual gives an example of A and B. They each have a 50% partnership share. The partnership owns two farms, A and B are not connected, and they decide to go their separate ways in the worked example that HMRC sets out in its manual. Those are the stated facts.
A takes one farm and B takes the other. A also pays B £100,000 as an equality payment. HMRC says the special rule in Schedule 15 paragraph 18 applies to each transfer.
- Start with the market value of the farm that leaves the partnership.
- Work out the sum of lower proportions, often called SLP.
- For A, A is a relevant owner because A receives the whole farm.
- A is A’s corresponding partner because A was a partner before the transfer.
- B is not A’s corresponding partner because B is not connected with A.
- A receives 100% of that farm after the split.
- A’s attributable partnership share is 50% in this example.
- The lower of 100% and 50% is 50%.
- So A’s SLP is 50%.
- The same approach gives B an SLP of 50% for B’s farm.
The legislation tells you to use market value multiplied by 100% minus the SLP when calculating SDLT. In this example, that means 50% of the market value of each farm.
What this means in practice
The £100,000 payment is not the whole story. You might assume that payment alone determines stamp duty. Under this special rule, HMRC says the starting point is instead each farm’s market value and the share retained through the partnership.
Where a farm is worth far more than the balancing payment, this distinction can change the SDLT figure substantially because the rule starts with market value rather than cash. That difference can be significant.
- Value each farm separately at the relevant time.
- Do not treat an equality payment as the only figure that matters.
- Check the ownership split before the farms are handed over.
- Check what each person receives after the split.
- Check whether either partner is connected with the other.
- Keep records that show why the partnership shares are 50:50, if that is the position.
How to analyse it
Work through the facts in order. Each farm drives the calculation. The overall fairness of the partnership split does not drive it.
- Is land leaving a partnership and going to a present or former partner?
- Which farm, or part of a farm, is being considered?
- Who owns that interest immediately after the transfer?
- Who was a partner immediately before it?
- Which of those people count as corresponding partners?
- What proportion of the farm does each relevant owner receive?
- What partnership share is attributable to each corresponding partner?
- For each person, which figure is lower?
- Add those lower figures to find the SLP.
- Apply the statutory formula to the farm’s market value.
There is an extra trap here: the partnership share used at this stage is a statutory figure, and the history of the farm entering the partnership and changes in the partner’s share can affect it. Its history can matter. A simple look at the current accounts may not settle it.
Example
Take HMRC’s example. A and B each have a 50% share in a partnership that owns two farms. A takes Farm 1, B takes Farm 2, and A pays B £100,000 to balance the deal.
For Farm 1, A owns 100% after the transfer but has a 50% attributable partnership share. The lower figure is 50%, so paragraph 18 applies to 50% of Farm 1’s market value. The same result applies to Farm 2 for B. The source gives no values for the farms, so it cannot show the final SDLT payable.
Why this can be difficult in practice
HMRC’s example produces a clean 50:50 result only because A and B have simple facts, equal partnership shares, unconnected status, and two farms that they divide between them. Real arrangements rarely stay so neat. A change in shares, a family link, or a company in the structure can affect who counts and what percentage is used.
- Partners may share profits differently from the way they describe ownership.
- A past change in shares can affect the attributable partnership share.
- Connected people are treated differently from unconnected former partners.
- The value of a farm can be disputed, especially where it includes land with different uses.
- One farm may have a different value from the other, even if the shares are equal.
- A dissolution does not necessarily prevent the rule applying while property is being distributed.
HMRC’s manual explains its view through one worked example. It is useful, but it is not the law itself. The legislation must decide the result where the facts differ.
Key takeaways
- A partnership split can trigger a special SDLT calculation.
- The cash balancing payment may not be the figure used for SDLT.
- For HMRC’s unconnected 50:50 example, each farm is assessed at 50% of market value.
Technical analysis

Legislation
- FA 2003 section 104 — applies the partnership schedule to SDLT
- FA 2003 Schedule 15 para 18 — sets deemed payment on property leaving a partnership
- FA 2003 Schedule 15 para 20 — works out the sum of lower proportions
- FA 2003 Schedule 15 para 21 — defines the partner share used in the calculation
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
- The correct result depends on the market value of each farm and on how each partner’s attributable partnership share is worked out.
- The source does not give the farms’ market values, so it does not permit a final SDLT amount to be calculated.
- For a transaction after 17 November 2025, the current statutory position must be checked against official legislation before publication or reliance.
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 each partner’s profit share
- documents showing how and when the farms became partnership property
- the transfer documents and equality-payment terms
- market valuations for each farm at the transfer date
- details of any connection between the partners or related parties
