Considerations When Restructuring a Business

Business restructuring can create opportunities for growth, asset protection, and succession, but each step has potential tax consequences.

Whether you are planning a shareholder exit, incorporating a holding company, or separating assets, it is important to understand UK tax rules before making any changes.

This article discusses some of the most common restructuring methods and their key tax considerations.

Purchase of Own Shares

Purchase of company-owned shares (CPOS) occurs when a company buys back shares from one or more of its shareholders. This can be an effective exit for retiring shareholders when there are no external buyers, or when the remaining shareholders wish to keep their ownership within the family.

Under the Companies Act 2006, a company can buy back its own shares and cancel them or hold them as Treasury shares (up to a limit of 10% of the nominal share capital). Treasury shares can later be reissued or used in an employee share scheme.

From a tax perspective, payments to selling shareholders are usually treated as income distributions (taxed as dividends). However, if certain conditions are met, then the company may qualify for capital gains treatment, which often results in a lower tax rate. HMRC permission must be obtained before completion.

To qualify for capital treatment, a company must be trading and the repurchase must be profitable for that trading. The seller must be a UK citizen and have held the shares for at least five years, with significantly reduced interest (usually at least 75%).

It is important to comply with the requirements of the Companies Act, confirm that the Articles of Association permit a buyback, make cash payments from distributable profits, circulate the buyback agreement to shareholders, and file Forms SH03 and SH06 with Companies House. 0.5% stamp duty applies, and HMRC must be notified within 60 days.

Failure to follow these steps can lead to costly mistakes, so professional supervision is essential.

Share-for-Share Exchange

Stock-for-share swaps are typically used to incorporate a new holding company over an existing trading company. Shareholders simply exchange their shares Tradeco for shares in Tahanco in identical proportions.

If the transaction meets the requirements, it is not treated as a disposal, meaning there is no immediate capital gains tax liability. The new shares in Holdco “replace” the old shares in Tradeco.

No stamp duty applies if the ownership structure remains the same; however, any change in share ownership will result in the liability of stamp duty and, possibly, capital gains tax.

Benefits of Group Structure

A well-designed group structure can result in commercial and tax efficiencies. By forming a holding company, valuable assets such as property or excess cash can be held separately from the trading company, thereby providing effective asset protection.

The group structure also simplifies management across multiple subsidiaries and can reduce administrative complexity. From a tax point of view, dividends between company groups in the UK are tax-free, and assets can be transferred between groups without gain/loss.

A clear commercial rationale must always underlie a restructuring to ensure HMRC accepts the arrangement.

Substantial Share Ownership Exclusion (SSE)

Substantial Share Ownership Exemption (SSE) can allow a company to sell shares in another company without corporate tax.

To qualify, the seller must hold at least 10% of the common share capital for a continuous 12-month period in the previous six years and be entitled to at least 10% of the profits and assets at closing. The company being sold must be a trading company or holding company of a trading group.

Recent regulatory changes mean selling companies no longer need to conduct trading themselves, making the exemption more widely available.

If SSE applies, the sale proceeds are tax-free. For shareholders who wish to obtain Business Asset Disposal Assistance (BADR), the parent company must be liquidated within three years of the sale. Otherwise, the holding company may be maintained as a Family Investment Company (FIC) to manage long-term wealth.

Before the sale, consider transferring shares into a family trust while Business Relief is still in effect. From April 2026, each trust will have a grant cap of £1 million each, so early action can help maximize the benefits. Although trusts may require periodic fees and out-of-pocket costs, they remain a valuable succession planning tool.

Capital Reduction Demerger

A capital-reducing demerger allows parts of a business to be separated into a new company without incurring immediate tax costs. This is often used to move trading premises or investment property out of the trading company prior to sale.

If transferred directly, the asset will usually result in a capital gain or stamp duty land tax liability. Capital reduction demergers, if properly implemented, allow transfers to occur tax-free, although the legal and professional costs can be substantial.

The process is technically complex, and HMRC permission must always be obtained. HMRC generally approves separation if there is a clear and bona fide commercial purpose.

In conclusion

Restructuring can be a powerful way to achieve strategic objectives, whether it is succession planning, asset protection, or preparation for a future sale. However, the tax and legal requirements are detailed and interconnected.

Initial advice is vital to ensure the structure functions as intended, HMRC permission is secured where required, and the result is tax compliant and efficient.
