- Check profit shares before and after the change.
- Do not look only for a land transfer.
- Other partnership SDLT rules decide the wider tax result.

SDLT when a partner’s partnership share increases
If your share of a property partnership goes up, stamp duty may need checking even if nobody transfers land. The increase counts as a transfer.
What this rule is about
Partnerships can own land for their business. A change in who receives the profits can therefore matter for SDLT. Looking only at the Land Registry will not always give the full answer.
What the official source says
HMRC’s manual points to a rule in the legislation. Where a person becomes entitled to a larger partnership share, whether because the profit split is revised or for another reason, HMRC’s manual says legislation treats the increase as a transfer of an interest in the partnership. That is the rule.
- The rule applies when a person becomes entitled to a larger partnership share.
- It treats that interest as moving to the partner whose share grows.
- It treats the interest as moving from the other partners.
- A partnership share means a person’s share of the partnership’s income profits.
What this means in practice
Although nobody need formally sell land, a revised profit split can cause the special partnership SDLT rules to treat the increased share as transferred from the other partners to you. That can be enough.
- Check changes to profit-sharing terms, not just changes of partners.
- Compare each partner’s share immediately before and after the change.
- Check the separate SDLT rules that may apply to the transfer.
How to analyse it
Start with the numbers. Compare the shares before and after.
- Identify the partnership’s income-profit shares before the change.
- Identify the shares after the change.
- Work out whose share increased and whose share fell.
- Check whether the partnership holds land for its business.
Example
Ada and Ben each receive 50% of a partnership’s income profits. They change this so Ada receives 70% and Ben receives 30%. Ada’s extra 20% counts as an interest transferred to her from Ben. This example does not, on its own, work out whether SDLT is due.
Why this can be difficult in practice
Land ownership is only one question. That is not the only question. The agreement may separate profit rights from other rights, so its wording matters.
- A new partner joining may change every existing partner’s share.
- A capital split may differ from the income-profit split.
- Informal changes can be harder to date and prove.
Key takeaways
- A larger profit share can count as a transfer.
- No land transfer is needed for this rule.
- The partnership agreement is key evidence.
