What Is a Statutory Demerger?

Statutory demergers in the UK are legal mechanisms that allow a company to split its business into two or more independent parts, each operating through a separate legal entity. Commonly used for restructuring, succession planning, or shareholder separation, it allows a company to reorganise without triggering immediate tax liabilities or needing to sell assets. 

These demergers are governed primarily by the Companies Act 2006 and relevant provisions of the Corporation Tax Act 2010. If structured correctly, statutory demergers can be extremely tax-efficient and strategically valuable. 

Our UK demergers accounting and tax guide explores this further.

Why Consider a Statutory Demerger?

There are several strategic and commercial reasons businesses opt for a statutory demerger:  

• To separate distinct business divisions (e.g., splitting a property business from a trading business) 

• For succession planning or family ownership restructuring 

• To allow different shareholder groups to pursue divergent strategies

• To prepare part of the business for sale, listing, or external investment

• To create ring-fenced liabilities or reduce operational risk 

Properly executed, a demerger can simplify corporate structure while offering significant legal and tax advantages.

Types of Statutory Demergers

In the UK, statutory demergers take one of two primary forms: direct and indirect. 

Direct Statutory Demerger

In a direct demerger, the parent company sets up a new subsidiary and transfers one of its trades into it. It then distributes the shares in that new company to its shareholders as a dividend in specie — that is, a non-cash distribution. 

• No consideration is given by shareholders 

• The distribution must be lawful under the Companies Act 2006 (i.e., from distributable reserves) 

• This is the simpler and more common route 
  

Typical use case: A family business splits its operations so that each family branch runs a separate trade. 

Indirect Statutory Demerger

An indirect demerger is slightly more complex. The parent company transfers a trade into a newly formed company (NewCo). However, instead of the parent receiving shares in NewCo, NewCo issues its own shares directly to the parent’s shareholders as consideration for receiving the trade. 

Key points: 

• No other consideration is given by the shareholders 

• Legally, this is still a distribution in kind

• Requires the parent company to have sufficient distributable reserves

• Allows for more flexible ownership structuring  

Typical use case: A trade is hived off to prepare for investment while giving shareholders direct ownership. 

Statutory vs Non-Statutory Demergers

A non-statutory demerger typically involves a reduction of capital or a sale to a new group company followed by a capital distribution. While this offers more flexibility, it often carries greater tax and legal complexity.  Learn more about capital reduction demergers here.

Feature	Statutory Demerger	Non-Statutory Demerger
Simplicity	Relatively straightforward	Often more complex legally
Tax treatment	Usually tax-neutral if conditions met	May trigger gains or tax liabilities
Use of new companies	Required (NewCo must be formed)	May or may not require NewCo
Legal basis	Companies Act 2006, CTA 2010	Often involves capital reduction

HMRC Clearance

Before undertaking a statutory demerger, it's highly advisable to obtain advance clearance from HMRC under Sections 1091–1093 of the Corporation Tax Act 2010. 

This clearance confirms that the proposed demerger is not for the purpose of tax avoidance, and ensures that: 

• No immediate capital gains tax liability arises 

• The demerger qualifies for tax neutrality

• HMRC agrees the transaction will be treated as a reconstruction
  

Clearance is not legally required, but most advisers consider it essential for managing risk. This tax-efficient business split is another option to consider.

Legal and Practical Requirements

To lawfully carry out a statutory demerger: 

• The parent company must have sufficient distributable reserves

• The board must consider solvency under the Insolvency Act 1986

• Corporate actions such as share issues and distributions must be properly documented

• Considerations around employee transfers, contract novation, and bank consent should be addressed 
  

Common Pitfalls to Avoid

Many demergers stumble due to inadequate planning or misunderstanding of the legal mechanics. Common mistakes include: 

• Failing to confirm the company has distributable reserves

• Neglecting to obtain HMRC clearance

• Assuming all contracts and liabilities automatically transfer 

• Ignoring the shareholder agreement or articles of association

Legal and tax advice should be obtained early — ideally during the structuring phase. 

Conclusion

Statutory demergers are a powerful way to separate business activities, unlock value, and simplify ownership structures all in a tax-efficient and legally compliant manner. Whether you opt for a direct or indirect route, careful planning and expert advice are essential.  See our article on strategic business separation for broader context.
