Group relief: when a change in control may undo stamp duty relief
In short
HMRC says a company can retain the same control even after one shareholder leaves. It looks for the smallest combinations of people that could control the company before and after the change.
- A share sale is not automatically a change in control.
- Several different groups can control a company at once.
- Share options and rights attached to shares may matter.
- HMRC guidance is not a substitute for the legislation.

Group relief: when a change in control may undo stamp duty relief
Group relief: when a change in control may undo stamp duty relief
A change in a company’s shareholders does not always mean stamp duty relief is lost. HMRC says it examines who truly controlled the company before and after the change. Its approach is known as the minimum controlling combination test.
What this rule is about
Group relief can remove stamp duty land tax when property moves between companies in the same group. Relief may later be taken back if, after the property transfer, the group relationship ends in a way that the law specifically sets out for that purpose. That later event matters.
Extra care is needed in one situation: the company selling the property leaves the group. The earlier relief may be at risk if control of the buying company then changes.
That may seem strange. The property has not moved again. Still, a later share deal can matter.
The law applies company-control rules to answer that question, and several people, or several different combinations of people, may control a company simultaneously for these purposes. That possibility matters.
What the official source says
HMRC’s manual says it applies a minimum controlling combination test. Put simply, it leaves out people who are not required to form a controlling group.
This is HMRC guidance rather than law. The legislation states when relief can be withdrawn and directs readers to the wider company-control rules.
- Start by identifying every smallest group of people that controlled the company before the share change.
- Do the same after the share change.
- Ignore a larger group if a smaller group within it already had control.
- If at least one smallest controlling group remains, HMRC says there has not been a relevant control change for this purpose.
- If no such group remains, HMRC says there has been a change in control.
HMRC provides a straightforward example. A, B and C each own one third of a company. They are not linked in a way that allows one person’s rights to count as another’s.
Each pair holds two thirds, meaning A and B, B and C, and A and C can each control the company. The three together are not treated as a minimum group because one member is not needed.
- If A leaves, B and C controlled the company before and still control it afterwards.
- HMRC says that outcome does not trigger a change in control.
- If A and B leave and D and E replace them, B and C no longer remain as a controlling pair.
- HMRC says a change in control has then occurred.
The manual also warns that, where an option gives an inalienable right to shares after its conditions have been met, both the existing shareholder and the option holder may be treated as having control. That right is enforceable.
HMRC says the key point is when the option gives an inalienable right to shares. This means a right that has become enforceable because its conditions have been met.
What this means in practice
Rather than treating the share transfer as the whole answer, ask whether any smallest group that controlled the company before the transfer continues to do so after it, despite the share movement in question. That comparison is central.
This can prevent an unfair result for a group. One investor may leave, while the people who could already control the company remain unchanged.
It can also create a difficulty that a simple share percentage does not reveal. Control can arise not only through voting rights but also through rights to assets on a winding-up or through other rights attached to shares. Percentages alone may mislead.
- Check the position before and after each share change.
- Look beyond ordinary share percentages.
- Include rights under options where they have become enforceable.
- Check whether the people involved are connected or can act through each other.
- Keep the documents that show why a controlling group has remained in place.
The same broad issue can arise under the separate rules for reconstruction and acquisition relief. Those rules can withdraw relief if control of the company that received the business changes within the statutory period and the relevant property is still held.
How to analyse it
Follow the share history in date order. A clear chart often helps more than a lengthy explanation.
- Identify the property transfer that received relief.
- Check which withdrawal rule applies to that relief.
- Record when the seller left the group, if it did.
- List each person’s voting and other relevant rights before the share change.
- List those rights again after the share change.
- Identify each smallest group that could control the company at both dates.
- Compare the two lists and see whether any minimum group remains.
- Check all options and the date any conditions became satisfied.
- Check whether the company or a related company still held the property at the relevant time.
What should you not do? Do not merely add up shares and assume that a new shareholder means relief must be lost. HMRC’s own example shows why that approach can be wrong.
Example
Ruth, Imran and Lee each own 33.33% of Northgate Ltd. None has rights that can be added to another person’s rights. Before any change, Ruth and Imran, Ruth and Lee, and Imran and Lee are each minimum controlling groups.
Ruth sells all her shares. Imran and Lee then own 50% each. On HMRC’s stated approach, Imran and Lee controlled the company before Ruth left and still control it afterwards. Her departure alone does not create the control change described in the manual.
Now change one fact. Ruth and Imran both sell their shares to Priya and Tom. Lee remains, but the earlier minimum group of Imran and Lee has disappeared. On HMRC’s example, no earlier minimum controlling group remains. That points to a change in control.
Why this can be difficult in practice
Control is not always the same as owning more than half the ordinary shares. Company documents may allocate different rights to different people, while an option may alter the control answer even before any shares are issued under the option. The register may not show it.
This is the point people often miss: several different groups can control one company at once. A change affecting one group may matter unless another minimum controlling group remains.
- Equal shareholdings can produce several controlling pairs.
- A shareholder agreement may alter who can direct decisions.
- Options may matter before the option holder appears on the share register.
- Rights to company assets on a winding-up can produce a different control result.
- Connected people may need to be considered together.
- HMRC’s manual does not replace the statutory control test.
The manual uses an older statutory reference for control. The current SDLT provisions refer instead to the Corporation Tax Act 2010. This makes current-law checking particularly important where a transaction or share change is recent.
Key takeaways
- A share change does not automatically undo group relief.
- HMRC looks for the smallest groups that could control the company.
- Options and share rights can change the result.
- Keep a dated record of ownership and control before and after the change.

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 HMRC page refers to an older control provision in the Income and Corporation Taxes Act 1988, while the current SDLT legislation refers to Corporation Tax Act 2010 sections 450 and 451.
- The source says HMRC will apply the minimum controlling combination test for SDLT, but it does not fully explain how that view applies to every type of company restructuring relief.
- Share options are especially fact-sensitive. The source does not settle every question about when an option gives a person an enforceable right to shares.
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.
- share registers immediately before and after each change
- articles of association and shareholder agreements
- details of voting, income and winding-up rights
- all option agreements and the dates conditions were met
- a dated group structure chart
- documents showing which company still held the property
