Alphabet Shares: How Different Share Classes Can Reduce a Company Director's Tax Bill

What Are Alphabet Shares and How Do They Work?

Most private limited companies start with a single class of ordinary shares, where every share carries the same rights to votes, capital and dividends. When a dividend is declared, all shareholders receive the same amount per share.

Alphabet shares change this structure by creating multiple classes of ordinary shares -- often called A ordinary shares, B ordinary shares, C ordinary shares and so on. The company's articles of association and any shareholders agreement define what rights each class carries. Crucially, different classes can receive different dividend amounts, declared independently by separate class resolution of that share class's holders.

A simple example:

• Director A holds 1 A ordinary share
• Spouse holds 1 B ordinary share
• The company declares a dividend of £50,000 on A shares and nil on B shares this year
• Next year, the company may declare nil on A and £20,000 on B, or any other combination

This flexibility allows the business owners to direct company profits to whoever will pay least tax on them in any given tax year -- typically the spouse with the lower income or unused personal allowance.

The shares themselves are equal in terms of voting rights and entitlement to capital on winding up (unless the articles say otherwise). The only difference is in dividend entitlement, which can be varied year to year.

The Tax Saving Calculation

In 2026/27, dividend income tax rates are:

• Basic rate: 8.75% (on dividends above the personal allowance and within the basic rate band)
• Higher rate: 33.75% (on dividends in the higher rate band)
• Additional rate: 39.35% (on dividends above £125,140)
• Dividend allowance: £500 (first £500 of dividend income tax-free)

A director with other income of £60,000 pays higher rate dividend tax at 33.75%. A spouse with no other income pays:

• Nil on the first £12,570 (personal allowance)
• Nil on the next £500 (dividend allowance)
• 8.75% on dividends from £13,071 to £50,270

Potential saving on £20,000 directed to a basic-rate spouse:

If the director had received it: 33.75% x £20,000 = £6,750 If the spouse receives it (assuming within basic rate band): 8.75% x approx £6,930 (above PA and DA) = approx £606

Tax saving: approximately £6,144 on £20,000 of dividends.

The saving is even greater if the spouse has no income at all and the dividends fall within their personal allowance -- in which case the first £13,070 of dividends are entirely tax-free.

The Legal Framework: Company Law Requirements

Implementing alphabet shares requires proper legal steps:

1. Amend the articles of association: The company's articles must be amended by a special resolution (75% majority) to create the new share classes. A solicitor should draft the amended articles to ensure the class rights are correctly described.

2. Issue new shares or convert existing shares: New shares can be issued at par value or shares can be converted. Share allotments must be reported to Companies House on form SH01 within 30 days.

3. Enter shares in the register of members: The company's statutory register of members must record each shareholder and their share class.

4. Declare dividends correctly: For each class, the shareholders of that class pass a written resolution or board resolution approving the dividend. The amount and date must be correctly documented.

5. Consider a shareholders agreement: While not legally required, a shareholders agreement between A and B shareholders clarifies expectations, procedures and what happens on exit, divorce or death.

Shortcuts here are dangerous. If dividends are paid without proper class resolutions, or if the articles do not properly define the classes, the entire structure may fail legally and could be challenged by HMRC as a distribution in a form that ignores the corporate formalities.

Anti-Avoidance: The Settlements Legislation

The main risk in alphabet share planning is the settlements legislation under section 624 ITTOIA 2005. This provision catches arrangements where someone (the "settlor") arranges for income to be paid to another person (the beneficiary) and the settlor retains an interest in the arrangement.

HMRC's argument in alphabet share cases is typically:

• The director set up the arrangement
• The spouse received income (dividends) they would not otherwise have received
• The director retains control over whether dividends are paid at all
• Therefore this is a settlement and the income is taxed on the director

The Arctic Systems Case

The landmark case is Jones v Garnett (Arctic Systems Ltd) decided by the House of Lords in 2007. The facts: Mr Jones ran an IT contractor company through which he provided his services. His wife held shares and received dividends. HMRC argued this was a settlement.

The House of Lords ruled against HMRC. The shares were an outright gift -- they carried real rights including capital rights -- and outright gifts are explicitly excluded from the settlements legislation by section 626 ITTOIA 2005 (the "outright gifts" exemption). HMRC lost.

However, this was not a blanket endorsement of all alphabet share arrangements. The Lords noted that if the shares had been "wholly or substantially a right to income" -- i.e., had no real capital value and existed purely as an income conduit -- the outcome might have been different.

When HMRC Is Likely to Challenge Arrangements

Since Arctic Systems, HMRC has continued to challenge arrangements it considers lack genuine substance:

High-risk indicators:

• Shares are created with no or nominal capital value and can be bought back immediately for next to nothing
• The spouse has no genuine economic stake or involvement in the business
• The arrangement is designed specifically to divert income and has no other commercial rationale
• Only one class of share pays dividends in practice, consistently
• The articles include put/call options that allow the company to buy back shares at par at any time

Lower-risk features:

• The spouse actually works in the business (even part-time)
• Shares were gifted at or near market value with no strings attached
• Capital rights are genuine and proportionate
• Dividends are paid on all classes, not systematically concentrated on the lower-rate spouse
• The spouse retains the shares and their economic interest is real

HMRC can invoke the general anti-abuse rule (GAAR) in extreme cases, though this is rare in practice for straightforward spouse-dividend arrangements where Arctic Systems principles are followed.

Alternatives and Complementary Planning

Alphabet shares are not the only tool for director tax planning, and in some cases lower-risk alternatives are worth considering first:

Optimal salary and dividend mix: Even without alphabet shares, directors should ensure they are taking the most tax-efficient combination of salary and dividends. In 2026/27, a typical director salary of £12,570 (using the personal allowance) plus dividends to the upper basic rate limit is a common and well-established approach.

Genuine spousal employment: Paying a spouse a salary for work they genuinely do in the business is fully deductible and carries much lower HMRC risk than alphabet shares -- provided the salary is commercially reasonable for the work done and is actually paid.

Pension contributions: Employer pension contributions are deductible from corporation tax profits and do not attract employer NI. For directors at or near higher rate, contributing to a pension before extracting profits can be more efficient than additional dividends.

Director loan account management: In the early years of a company, shareholder loans and director loan accounts can sometimes provide a more flexible route to extracting cash, though these must be managed carefully to avoid the 32.5% s.455 charge.

For many owner-managed businesses, a combination of alphabet shares (properly structured with legal advice), salary optimisation and pension contributions provides the most robust and tax-efficient outcome. The key is ensuring that any alphabet share arrangement has genuine commercial substance and that the legal documentation is correctly executed and maintained.
