Stamp duty and partnerships: the key definitions
When land is held through a partnership, stamp duty can depend on definitions that are easy to overlook. This HMRC page is only a contents list, but it points to the terms that may determine which partnership rules need checking.
What this rule is about
Part 3 of Schedule 15 sets out special SDLT rules for certain partnership changes. It covers land moving into or out of a partnership, along with certain changes in a partner’s share.
The labels matter. SDLT may apply without a land transfer.
What the official source says
HMRC’s page links to separate manual pages that explain the main definitions and types of transfer, while Schedule 15 contains the legal rules that govern them. HMRC guidance is not law.
- Land held for the partnership business is partnership property.
- A partnership share means a person’s share of income profits.
- Land becoming partnership property counts as a transfer to the partnership.
- A person gaining or increasing a partnership share counts as receiving a partnership interest.
What this means in practice
Do not look only at the Land Registry title. You must also check who shares the partnership’s income profits, how those shares change, and whether anything else changes at the same time in the arrangement. Title alone is not enough.
- Record each partner’s profit share before and after the change.
- Check whether land has become, or stopped being, partnership property.
- Check links between the people involved and any wider deal.
How to analyse it
Start by identifying what changed, then apply the definitions. Only then can you work out which detailed partnership rule may apply.
- Identify the land and who held it before the event.
- Find out whether it was held for the partnership business.
- Compare each partner’s income-profit share before and after.
- Review all agreements, including informal understandings.
Example
Amir and Beth run a property business together. Beth’s share of its income profits rises from 40% to 60%, while the partnership continues to hold a shop throughout the change. The shop stays with the partnership. For these rules, Beth has increased her partnership share. That counts as a transfer of a partnership interest. It does not, by itself, settle the SDLT amount.
Why this can be difficult in practice
People often assume a change is irrelevant when the land title stays unchanged, even when the partnership agreement and real deal may matter more than that title. That assumption can be wrong.
- Partners are not treated as connected merely because they are partners.
- The connected-person test has special changes for these rules.
- Arrangements include a scheme, agreement or understanding, even if it cannot be enforced.
Key takeaways
- This HMRC page is a signpost, not a tax calculation.
- Profit shares can matter as much as title ownership.
- Check the full partnership arrangement before reaching a conclusion.

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 SDLT result depends on the full facts, including the land, ownership before and after the change, and any connected people or arrangements.
- The supplied statutory text is current only to 17 November 2025. Current legislation should be checked for a later transaction.
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.
- partnership agreement and any changes to profit shares
- land title documents and details of beneficial ownership
- documents recording any agreement or informal understanding
- details of relationships relevant to the connected persons test
