A share buyback occurs when a company purchases its own shares from one or more shareholders. The shares are usually cancelled, reducing the number in issue, although treasury shares may be permitted in limited circumstances.

A company may use a buyback to return surplus cash, provide an exit for a shareholder, simplify its ownership structure, or support an employee share arrangement. The commercial effect depends on the transaction terms. Remaining shareholders may hold a larger percentage of the company, but the company will also have fewer cash resources. The board should record the commercial rationale and assess the effect on creditors, working capital and future funding.
The Companies Act 2006 sets the main rules for a buyback by a UK company. The shares must generally be fully paid, and the company must have authority in its articles and from its shareholders. An off-market purchase normally requires the purchase contract, or its terms, to be approved by an ordinary resolution before completion. The company must also identify a permitted source of funds. Common routes include distributable profits or the proceeds of a new share issue. A purchase out of capital involves additional statutory conditions, including director statements, shareholder approval and, in some cases, an auditor’s report.
The board should review the articles of association, shareholder agreement, existing share rights and any financing restrictions before agreeing terms. It should also consider whether the transaction creates a conflict for directors, affects pre-emption rights, or requires separate treatment for different shareholder groups. The price and terms should be supported by a clear valuation process, particularly where the selling shareholder is a director, employee or connected person.
The company should document the transaction in a share buyback agreement and complete the required corporate approvals. After completion, it must update its register of members and deal with the bought-back shares in accordance with the legislation. Form SH03 is generally filed at Companies House within 28 days of the purchase. If the shares are cancelled, form SH06 is also normally required. The company should retain the resolutions, contract, payment evidence and updated cap table with its statutory records.
The seller’s tax treatment depends on factors such as the seller’s status, the number of shares sold, the price and the circumstances of the transaction. A payment can have income tax or capital gains tax consequences, and a tax clearance application may be relevant where capital treatment is intended. The company should obtain tax input before fixing the structure or price. A practical process is to begin with the commercial objective, confirm the funding route, check the articles and shareholder documents, agree valuation principles, prepare the approvals and contract, then complete the Companies House filings.
