SDLT when property leaves a partnership: when missed tax on entry makes your share zero
In short
When property leaves a partnership, SDLT may use a special version of a partner’s profit share. It depends on when the land entered and how earlier transfers were taxed.
- Start with the right historic date.
- Check evidence of SDLT or stamp duty treatment.
- Track later share increases and decreases.

SDLT when property leaves a partnership: when missed tax on entry makes your share zero
When land leaves a partnership, stamp duty may depend on more than your share today. The key question is often how the land first entered the partnership, and whether the right tax was dealt with then. That history can change the amount treated as paid for the land.
What this rule is about
A partnership share usually means the share of the partnership’s income profits that a partner is entitled to receive. It is not simply the share shown beside a person’s name on a Land Registry title.
That sounds like a small distinction. It can make a large difference.
This special rule matters when land moves from a partnership to a current or former partner, or to someone linked to one. The law works out a figure called the sum of the lower proportions. It then uses that figure to calculate the amount treated as paid for the land.
For each relevant person, the calculation compares two percentages: their share of the land they receive and their attributable partnership share. The lower percentage is used.
What the official source says
HMRC’s manual explains that special rules apply when working out the partnership share for this calculation. The legislation, rather than the manual, is what decides the result.
- If the land entered the partnership before 20 October 2003, the special starting-date rules apply.
- If it entered on or after that date and the required SDLT was paid, or the document was properly stamped with ad valorem stamp duty, the special rules also apply.
- If it entered on or after that date, and neither the SDLT requirement nor the ad valorem stamp duty requirement was met, the attributable share is zero. That is the result.
- A zero attributable share can mean the full market value is used when working out the amount treated as paid for the land leaving.
- Where the special rules apply, begin with the partner’s actual income-profit share on the relevant starting date.
- Add later increases that count under the legislation.
- Subtract later decreases, but never take the result below zero.
For land that entered before 20 October 2003, the starting date is 19 October 2003. If the person joined later, use the date they joined instead.
For land that entered on or after 20 October 2003 with the required tax treatment, start on the effective date of that transfer. Again, use the later joining date if the person joined afterwards.
What this means in practice
You cannot safely use only the partnership’s current profit-sharing ratio. A partner may now have a 50% share, but the figure used in this calculation may be lower because of the land’s history.
The reverse can happen too. A later increase can count only if it satisfies the tax condition set by the legislation.
- Keep the papers for the original transfer into the partnership.
- Check whether SDLT was paid or an older document was properly stamped.
- Find the partnership agreement in force at each key date.
- Check changes in profit shares, not just changes in legal ownership.
- Separate increases in a share from decreases in a share.
- Do not assume that a dissolved partnership ends the issue before land is handed out.
This is the part people often miss: a past failure to deal with tax when land entered the partnership can affect a later transfer out.
How to analyse it
Start with the property, then work backwards. The calculation needs a clear timeline, not a guess based on the partnership’s position today.
- Confirm that land is leaving the partnership and identify who will receive it.
- Identify everyone who held a share immediately before the transfer and everyone who receives a share afterwards.
- Find the date when the land became partnership property.
- Decide whether that date was before, or on or after, 20 October 2003.
- For a later transfer in, check the evidence of SDLT payment or proper ad valorem stamping.
- Set the correct starting date for each partner.
- Find that partner’s income-profit share on the starting date.
- Add only later increases that meet the required tax condition.
- Deduct all later decreases and stop at zero.
- Compare that result with the share of land the person receives. Use the lower figure.
Example
Here is an illustration. A partnership transfers land worth £1,000,000 to Maya. She receives 50% of the land. The land entered the partnership after 20 October 2003, and SDLT was correctly paid at that time.
Maya’s income-profit share was 40% on the transfer-in date. It later rose by 10%, following a transfer that met the required tax condition. Before the land left, it fell by 5%. Her attributable share is therefore 45%.
Maya receives 50% of the land, but her attributable share is 45%. The lower figure is 45%. For this part of the calculation, £450,000 is the amount treated as paid.
Change one fact and the answer may be starkly different. If the land entered after 20 October 2003 and the required tax was not dealt with, Maya’s attributable share would be zero.
Why this can be difficult in practice
Old partnerships do not always have neat records. Profit shares may have changed informally, or accounts may not match later documents. The facts, rather than the label on a form, matter.
You might think a rise in someone’s share always helps. It does not. The legislation permits a later increase to count only where the increase itself satisfies the stamp duty or SDLT condition that it must meet. Otherwise, it does not count.
- A capital-sharing ratio may differ from the income-profit ratio required by the rule.
- A person may have joined after the land entered the partnership.
- A former partner can still be relevant when land is transferred out.
- There may be no clear proof that tax was paid on an old transfer or share increase.
- Several people may receive interests in the land, requiring separate comparisons.
- Using the current percentage without rebuilding the timeline can produce the wrong figure.
Key takeaways
- Your current partnership share may not be the figure used.
- The date land entered the partnership is central.
- Evidence of earlier tax treatment can change the result.

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 result can depend on old transfer documents, the tax treatment of earlier share changes, and the dates on which people became or ceased to be partners.
- It may be difficult to establish the income-profit shares in an old or informal partnership.
- The supplied legislation is confirmed only through 17 November 2025. Current-law verification is needed for a transaction after that date.
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 document transferring the land into the partnership
- The effective date of that earlier transfer
- Evidence that SDLT was paid or the document was properly stamped where required
- Partnership agreements and accounts showing income-profit shares
- Documents recording each later change in partnership shares
- The document and ownership position for the land leaving the partnership
