# Ordinary Share Capital: A UK Tax & Legal Guide for 2026/27

Ordinary Share Capital is a cornerstone concept in both UK company and tax law, forming the basis of company ownership and affecting eligibility for numerous tax reliefs. While seemingly straightforward, the precise definition depends entirely on the specific rights attached to a share, not the name it is given.

This guide provides a detailed analysis of what constitutes Ordinary Share Capital for tax purposes, breaking down the statutory definition and exploring practical examples based on case law and HMRC guidance.

## The Core Tax Definition

For both [Income Tax](https://www.accountingfirms.co.uk/blog/tell-hmrc-that-your-company-is-dormant/) and Corporation Tax purposes, the UK legislation provides an identical definition of Ordinary Share Capital.

> **Corporation Tax Act 2010, section 1119 & [Income Tax](https://www.accountingfirms.co.uk/blog/hmrc-payment-niers/) Act 2007, section 989** “Ordinary share capital, in relation to a company, means all the company’s issued share capital (however described), other than capital the holders of which have a right to a dividend at a fixed rate but have no other right to share in the company's profits.”.

This definition can be broken down into two essential components:

1. It must be part of the company’s **issued share capital**.
2. It must **not** be capital where the holder’s rights are restricted to only a fixed-rate dividend.

The reference to share capital "however described" makes it clear that the label given to a share class (e.g., "preference share", "A ordinary share") is irrelevant; the analysis must focus on the underlying rights set out in the company's articles of association.

This tax definition is similar in effect to the company law definition of "equity share capital" found in section 548 of the Companies Act 2006.

## The "Fixed Rate" Dividend Test

The crucial element of the definition is identifying and excluding shares that have a right to a dividend at a "fixed rate" but no other right to share in profits. The practical application of this test can be complex. [HMRC guidance](https://www.accountingfirms.co.uk/blog/how-to-navigate-changes-in-tax-laws/) and case law provide clarity on various scenarios.

The following table summarises how different dividend rights affect a share's classification as Ordinary Share Capital.

| Share Type / Dividend Right | Classification | Rationale |
| --- | --- | --- |
| **Standard Fixed Rate Preference Share** (e.g., 5% cumulative/non-cumulative) | NOT Ordinary Share Capital | The right to a dividend is at a fixed rate, and there is no other right to share in profits. The fact a dividend is cumulative does not change the fixed nature of the rate. |
| **Shares with No Dividend Rights** | Ordinary Share Capital | The legislation only excludes shares with a fixed-rate dividend. A right to nothing is not a right to a fixed dividend. |
| **Shares with "Tiered" Dividends** (e.g., 8% in year 1, 9% in year 2) | Ordinary Share Capital | The rate is not fixed as it changes over time. The legislation refers to "a fixed rate" in the singular. |
| **Compounding Preference Shares** (where unpaid dividends are added to the principal) | Ordinary Share Capital | Although the percentage rate is fixed, the amount to which it is applied varies over time. A fixed rate requires both the percentage and the principal amount to be fixed. This was confirmed in *HMRC v Stephen Warshaw*. |
| **Shares with Variable Rate Dividends** (e.g., LIBOR + 2%) | Ordinary Share Capital | The rate is not fixed because the base rate (LIBOR) varies. |
| **Shares with a Right to a Further Contingent Dividend** (e.g., on breach of a banking covenant) | Ordinary Share Capital | The right to a further payment is another right to [share in the company's](https://www.accountingfirms.co.uk/blog/company-payment-of-directors-personal-expenses-whats-the-tax-position/) profits, taking it outside the exclusion. |

## Key Rights and Characteristics of Ordinary Shares

A share is best understood as a bundle of rights and liabilities that define a shareholder's relationship with the company. Ordinary Share Capital represents the equity and ownership interests of the members.

The principal rights that typically attach to ordinary shares are:

- **Voting Rights:** The right to vote on company matters, such as the appointment of directors.
- **Right to Dividends:** An entitlement to receive a proportionate [share of the company's distributed profits](https://www.accountingfirms.co.uk/blog/how-to-distribute-profit-shares-in-an-llp/), which are not fixed.
- **Right to Assets on Winding Up:** The right to share in the company's surplus assets after all creditors and preference shareholders have been repaid.

In contrast, preference shares typically carry a right to a fixed dividend, do not have voting rights, and have priority for repayment of capital if the company is wound up.

## Why the Definition is Important

The correct classification of a [company's share](https://www.accountingfirms.co.uk/blog/how-to-buy-shares-in-a-company/) capital is critical for determining its status for a wide range of tax purposes, including:

- **Group Relief:** Specific definitions of "ordinary shares" are used to establish group relationships.
- **Business Asset Disposal Relief:** An individual must hold at least 5% of the ordinary share capital and voting rights to qualify.
- **Distribution Exemption:** A dividend may be exempt if it is made in respect of a non-redeemable ordinary share.
- **Change of Ownership Rules:** The ownership of ordinary share capital is usually the primary test for determining if a change of ownership has occurred, which can affect the availability of tax losses. However, other factors like voting power can be considered in certain circumstances.
