Alphabet Shares and Share Classes in a UK Limited Company

Most UK limited companies are incorporated with a single class of ordinary shares. But you can create multiple share classes — commonly called 'alphabet shares' (A shares, B shares, C shares) — to give different rights to different shareholders. This is a legitimate tax planning tool widely used by UK owner-managed businesses, but it comes with important limits that Arab directors should understand before implementing it.

The main use case: dividend flexibility. With a single share class, dividends must be paid in proportion to shareholdings — every shareholder receives the same pence per share. With alphabet shares, you can pay different dividend rates to different shareholders in the same period. The most common structure: a director holds A shares, their spouse holds B shares. In a profitable year, you pay a higher dividend on B shares to use the spouse's unused personal allowance and basic rate tax band. In a lean year, you pay nothing on B shares. This flexibility is the core commercial purpose.

How to create alphabet shares: the company's Articles of Association must permit different share classes. Standard Model Articles can be amended. You then pass a shareholder resolution to create the new class, allot shares, and file SH01 (return of allotment of shares) with Companies House. The process is straightforward when done at incorporation or with professional help during a restructure. Each share class can be given different dividend rights, voting rights, and capital rights.

The settlements legislation risk: HMRC is well aware of alphabet share structures used to divert income to a lower-earning spouse. The settlements legislation (sections 624–626 ITTOIA 2005, arising from the Arctic Systems case) can treat dividends paid on a spouse's shares as still belonging to the higher-earning director if the arrangement was designed to reduce tax and the shares were gifted (not sold at market value) with no genuine commercial basis. The key test: did the spouse receive shares as part of a 'bounteous arrangement' that would not have been made on arm's length terms with a third party? If yes, HMRC can treat those dividends as the director's income.

What strengthens the structure's legitimacy: the spouse has a genuine, documented role in the business (even a limited one); the shares were transferred at market value or granted at incorporation for genuine consideration; the dividend rights are genuinely commercial share rights with capital rights attached, not purely a mechanism to strip income. If your spouse is also a working director or takes an active role, the position is significantly stronger than if they are a purely passive shareholder.

Other uses of different share classes: voting vs non-voting splits (founders retain control while bringing in investors); preference shares with a fixed dividend return (used in investment rounds); different rights on winding up. For Arab directors bringing in a co-director as a partner but wanting to retain voting control, B shares with economic rights but no voting rights is a clean solution.
