SDLT and stamp duty: when a partner’s 10% share blocks relief
SDLT and stamp duty: when a partner’s 10% share blocks relief
A business may lose a special SDLT, or stamp duty, relief if a partner who may live in the home has a stake of 10% or more. This can matter where a company or partnership buys a home for someone working in the business.
What this rule is about
The relief can remove the higher SDLT charge in some cases where a commercial business provides a home for workers. It is not a general exemption for partners.
One detail can decide the result: the proposed occupant’s financial share in the business or home.
What the official source says
HMRC’s manual says an individual partner is a qualifying partner unless their interest reaches 10%. The legislation is more precise. An individual partner remains a qualifying partner, but the relief condition is treated as failed if a proposed occupant has a 10% or greater relevant share.
- The person may have a 10% or greater share of partnership income profits.
- They may have a 10% or greater share in a company that beneficially owns the home.
- They may have a 10% or greater beneficial share in the home itself.
What this means in practice
If any likely partner occupant meets one of those tests, the business cannot meet this part of the relief. Calling the person a qualifying partner does not fix that problem.
- Check ownership before the purchase completes.
- Check profit shares, not only job titles.
- Check who is likely to live in the home.
How to analyse it
Start with the relief as a whole. Then test the proposed occupants and their interests at the relevant time.
- Is the home intended for business-related living accommodation?
- Is the business run commercially and to make a profit?
- Will a partner, or a group including a partner, occupy it?
- Does any such partner have a relevant share of 10% or more?
Example
Rosa is one of four partners in a business. She may live in a home bought for business use. If she has a 9% share of the partnership profits, this restriction alone does not block the relief. If her share is 10%, the accommodation condition is treated as failed. The other relief conditions still matter.
Why this can be difficult in practice
Partnership profit shares, company shares and beneficial ownership can differ. They may also change over time. This is the part people often miss.
- A legal title may not show the true beneficial shares.
- A profit-sharing agreement may override an assumed equal split.
- A group of possible occupants can be enough to trigger the restriction.
Key takeaways
- The 10% test can block this business-home relief.
- It applies to profits, company ownership and ownership of the home.
- Keep records showing shares and planned occupants.

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 supplied statutory text is current only to 17 November 2025. The law should be checked against the current official legislation for a later purchase.
- The answer may depend on who is likely to occupy the home and on their entitlement at the relevant time.
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.
- Signed partnership agreement and later amendments — who the partners are and how profits are shared
- Partnership accounts and profit-allocation schedules — the actual share of income profits for each partner
- Partnership tax returns and supporting calculations — how profits were reported and divided
- Companies House records, company register and share certificates — who owns shares in a company holding the home
- Land Registry title, filed plan and transfer document — who legally owns the home and in what shares
- Declaration of trust or beneficial ownership agreement — beneficial shares that may differ from the legal title
- Board minutes, business plan and purchase papers — why the home was bought and its planned business use
- Proposed occupancy list and tenancy or licence records — which people are expected to live in the home
