Stamp duty relief when a building society becomes a company
At a glance
A land transfer can be exempt from SDLT when a building society transfers its business to a company through a specified legal route.
- The exemption is in Finance Act 2003 section 64.
- It applies only to transfers under Building Societies Act 1986 section 97(6) or 97(7).
- Being part of a demutualisation alone does not settle the question.

Stamp duty relief when a building society becomes a company
A qualifying land transfer attracts no stamp duty when a building society transfers its business to a company. This SDLT exemption is narrow.
It can apply only where the land transfer follows one of the two routes specified in building society law. If it does not, the exemption cannot apply to that business transfer.
What this rule is about
As part of becoming a company, a building society may transfer its business to a commercial company. That business may include land. Without the exemption, transferring that land could give rise to stamp duty land tax.
The decisive issue is the legal route used for the transfer. A building society’s conversion into a company does not, by itself, qualify.
What the official source says
HMRC’s manual refers to Finance Act 2003 section 64. Under that section, a land transfer is exempt if it is effected under section 97(6) or 97(7) of the Building Societies Act 1986. Those are the identified routes.
- The transfer must involve a building society’s business.
- That business must move to a commercial company.
- The land transfer must be made under section 97(6) or section 97(7).
- If it is, the transfer is exempt from SDLT.
What this means in practice
Where land moves with the business through a qualifying route, the relief can prevent an SDLT bill that would otherwise arise because the land has moved.
The relief is limited. It does not provide a broader tax break for later sales, purchases or separate land transfers.
- Check the legal documents, not just the label “demutualisation”.
- Identify every property included in the business transfer.
- Keep the transfer scheme and supporting records.
- Separate later property deals from the qualifying transfer.
How to analyse it
Begin with the statute identified in the transfer papers. What decides the outcome? Whether the land moved through one of the two specified routes.
- Confirm that the transferor was a building society.
- Confirm that the business moved to a commercial company.
- Check whether section 97(6) or 97(7) was used.
- Match the land transfer to that business transfer.
Example
Illustration: a building society transfers its full business, including an office worth £2 million, to a company under section 97(6). Section 64 treats the land transfer as exempt.
The office’s £2 million value does not change that result. If the office is later sold in a separate deal, rather than as part of the qualifying business transfer, this exemption does not automatically cover the sale. It is separate.
Why this can be difficult in practice
People may focus on the commercial transaction and overlook the legal mechanism. That mechanism is what matters.
The supplied source identifies the two Building Societies Act routes. However, it does not give their detailed rules, which must still be established from the relevant law. That detail matters.
- A company transfer may not use either specified route.
- A later transfer may be separate from the business move.
- The documents must show how the land moved.
Key takeaways
- This is an exemption for a specific type of business transfer.
- The section 97 route is central to the answer.
- Check the current legislation for newer transactions.

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 Finance Act 2003 text is recorded only to 17 November 2025. Current primary legislation should be checked for a transaction after that date.
- The source does not explain the detailed requirements for using either Building Societies Act 1986 transfer route.
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.
- Documents showing that the business transfer was made under section 97(6) or section 97(7) of the Building Societies Act 1986.
- The transfer scheme and documents identifying the company receiving the business.
- Details of the land included in the business transfer.
