Share capital, nominal value and share classes explained

What is Share Capital?

Share capital is the total value of all shares issued to shareholders in a limited company. It represents the initial and subsequent investment made by the company's owners in exchange for an equity stake. When you form a company, you must decide on its share structure, which is documented in the 'statement of capital' as part of your application to Companies House. This capital forms a core part of the company's financial foundation, although in many small startups, the initial amount is nominal. The concept of share capital is fundamental to limited liability, as it typically represents the maximum amount a shareholder is liable to lose if the company fails—the value of their shares.

It's crucial to distinguish between 'issued' and 'paid-up' share capital. Issued share capital is the total nominal value of all the shares the company has allocated to shareholders. For example, if a company issues 100 shares with a nominal value of £1 each, its issued share capital is £100. Paid-up share capital is the portion of the issued capital that the shareholders have actually paid to the company. While shares must eventually be paid for, they don't always have to be paid for immediately upon issue. However, for most small companies formed online, the shares are issued and paid-up at the same time for simplicity. This initial fund, however small, legally belongs to the company, not the directors personally.

The primary purpose of share capital is to create a clear ownership structure. It defines who owns what percentage of the company and, depending on the share class, what rights they hold regarding voting and entitlement to profits. While it can be a source of funding, most new businesses rely on director's loans or external finance for working capital rather than a large initial share capital. Setting a low, simple share capital (e.g., 100 shares at £0.01 each) provides flexibility for future changes, such as bringing in new investors or creating employee share schemes, without creating unnecessary administrative or financial burdens at the outset. A large unpaid share capital can also appear as a debt owed to the company on the balance sheet, which can be unattractive to lenders or investors.

Worth knowing: Share capital is the foundational ownership stake in your company, defining who owns what and limiting shareholder liability.

Nominal Value Explained

Every share in a UK limited company must have a 'nominal value', also known as par value. This is a fixed, arbitrary price assigned to a share when it is created, and it is stated in the company's constitutional documents. The nominal value represents the minimum price for which a share can be issued. Common nominal values for new companies are £1, £0.10, or £0.01. It is a legal and accounting concept, not a reflection of the share's actual or market value. The market value of a share will fluctuate based on the company's performance, profitability, and prospects, while the nominal value remains fixed unless the company undertakes a specific legal process to change it.

Choosing a low nominal value, such as £0.01, is often the most practical approach for a new business. This provides maximum flexibility. For example, with a £0.01 nominal value, you can issue 10,000 shares for a total share capital of just £100. This makes it easy to divide ownership into small percentages and transfer shares without dealing with large sums of money. A higher nominal value, like £100 per share, can be restrictive. It would mean that even a 1% stake in a 100-share company requires an investment of £100, and issuing new shares requires a significant cash injection. Furthermore, a company cannot legally issue shares for less than their nominal value (issuing at a 'discount').

• Not Market Value: The most common mistake is confusing nominal value with the actual worth of a share. A £1 nominal share in a profitable company could be worth thousands.
• Issuing at a Premium: Shares can be issued for more than their nominal value. The excess amount is recorded in a 'share premium account'.
• Inflexibility of High Value: A high nominal value (e.g., £1,000) makes it difficult to issue small numbers of shares or create granular ownership structures.
• Minimum Issue Price: It is illegal to issue a share for a price below its nominal value.
• Currency: The nominal value must be in a specific currency (e.g., GBP, USD, EUR), which is fixed for each share class.

Worth knowing: The nominal value is an arbitrary minimum price for a share, and setting it low provides the greatest future flexibility.

Setting Your Initial Share Capital

When forming your limited company, you must provide a 'statement of capital' to Companies House. This statement outlines your initial share structure, including the number of shares, their nominal value, and the rights attached to them. For many small businesses, a simple and effective starting point is to issue 100 ordinary shares with a nominal value of £1 each. This creates a total issued share capital of £100. This structure is popular because it makes percentage calculations straightforward: each share represents exactly 1% of the company. If there are two equal founders, each can take 50 shares. If there is a sole founder, they will own all 100 shares.

Another common approach, particularly for a sole director/shareholder, is to issue just one ordinary share at £1. This is the simplest possible structure and is perfectly valid. It establishes the individual as the 100% owner. While simple, it can be less flexible if you plan to bring in partners or investors soon, as you would need to subdivide the share or issue new shares to accommodate them. Deciding between 1, 100, or even 1,000 shares is a matter of preference and future planning. Having more shares (at a lower nominal value, e.g., 10,000 shares at £0.01) can make it easier to transfer small equity percentages later on.

1. 1

   Decide on the founding shareholders and the percentage of ownership each will have.

2. 2

   Choose a total number of shares that makes these percentages easy to represent (e.g., 100 shares for simple percentages).

3. 3

   Select a low nominal value for each share, such as £1 or £0.01, for maximum flexibility.

4. 4

   Calculate the total issued share capital by multiplying the number of shares by the nominal value.

5. 5

   Specify this share structure, including the share class (usually 'Ordinary'), in your incorporation application (Form IN01).

6. 6

   Ensure each shareholder pays the company the total nominal value for their shares.

7. 7

   Record the founding shareholders and their shareholdings in the company's statutory register of members.

Worth knowing: For most startups, an initial share capital of 100 shares at £1 each is a simple, practical, and flexible starting point.

Ordinary Shares: The Default Choice

For the vast majority of new UK limited companies, 'Ordinary Shares' are the only type of share needed. They are the standard and most common class of share, and their rights are typically defined in the company's articles of association. Unless you specify otherwise, all shares are assumed to be ordinary shares. The fundamental principle of ordinary shares is that they carry equal rights. This means that each ordinary share gives its holder one vote at shareholder meetings, a right to a proportion of any dividends the company declares, and a right to a proportion of the company's assets if it is wound up, after all creditors have been paid.

The beauty of ordinary shares lies in their simplicity. If a company has 1,000 issued ordinary shares and a shareholder owns 100 of them, they hold a 10% stake. This entitles them to 10% of the total votes, 10% of any total dividend payout, and 10% of the final capital distribution. This direct link between ownership percentage and rights makes the structure easy to understand and manage. For startups with a small number of founders who intend to share in the risks and rewards of the business equally according to their holding, ordinary shares are the perfect instrument. There is often no need for more complex structures until the business grows, takes on external investment, or has specific tax or estate planning objectives.

Worth knowing: Ordinary shares provide simple, proportional rights to voting, dividends, and capital, making them the ideal default for most new companies.

Understanding Share Classes

While ordinary shares are sufficient for many, a company can create different 'classes' of shares with different rights. This is a powerful tool for tailoring the ownership structure to specific commercial, investment, or personal needs. By creating multiple share classes, you can separate or vary the three core rights: voting, dividends, and capital distribution. For example, you could create a class of non-voting shares for a family member you wish to give a financial stake to, but not control over the business. Or you could create a class of shares for an investor that gives them priority for dividend payments. Common labels for different classes include 'A' Ordinary, 'B' Ordinary, 'Preference', 'Non-Voting', or 'Deferred'.

The decision to use different share classes should be driven by a clear objective. Are you bringing in a silent investor who wants a return but no say in operations? Preference shares or non-voting shares might be appropriate. Do you need to incentivise a key employee without diluting the founders' control? You could issue them a class of shares with dividend rights but restricted voting rights. Another common use is in family companies, where founders may want to distribute profits flexibly between different family members who are shareholders. This is often achieved using 'alphabet shares' (see next section). Setting up different share classes requires careful drafting in the articles of association to precisely define the rights of each class. Ambiguity can lead to serious disputes later on.

• Control vs. Economic Interest: Separate voting rights from dividend/capital rights. Founders might hold 'A' shares with 10 votes each, while investors hold 'B' shares with 1 vote each.
• Employee Incentives: Issue a specific class of share to employees that may only gain full rights upon meeting certain targets or after a set period (vesting).
• Investment Structuring: Create Preference shares that guarantee an investor a fixed dividend or ensure they are paid back first if the company is sold.
• Estate and Tax Planning: Different classes can be used to pass value to family members in a tax-efficient manner, though this requires specialist advice.
• Defining Rights is Key: The articles of association must unambiguously state the rights for voting, dividends, and capital for each and every share class.

Worth knowing: Share classes allow you to customise ownership by assigning different voting, dividend, and capital rights to different groups of shareholders.

Alphabet and Preference Shares in Practice

‘Alphabet shares’ are simply ordinary shares divided into different classes, labelled A, B, C, and so on. For example, Shareholder 1 holds 'A' Ordinary shares, Shareholder 2 holds 'B' Ordinary shares. While they might have identical voting and capital rights, the key feature is often the ability to declare different dividends for each class. This means the directors can declare a dividend of £10 per share for the 'A' shares and £2 per share for the 'B' shares in the same financial year. This provides enormous flexibility for distributing profits, particularly in small family or owner-managed businesses where shareholders may have different personal tax situations or income needs. However, this flexibility comes with a health warning: HMRC may scrutinise such arrangements under the 'settlements legislation' if they are seen as a way of diverting income from a higher-rate taxpayer to a lower-rate one without a genuine commercial basis.

'Preference shares' are another common class, typically issued to external investors. Their defining characteristic is that they have preferential rights over ordinary shares, usually regarding dividends. A preference share might entitle the holder to a fixed, cumulative dividend (e.g., 5% of their initial investment per year) which must be paid before any dividends can be paid to ordinary shareholders. If the company cannot afford to pay it one year, a cumulative dividend right means the arrears are carried forward. Preference shareholders also often have the right to be repaid their initial investment capital before ordinary shareholders if the company is sold or wound up. The trade-off is that preference shares often carry limited or no voting rights, reflecting the holder's status as a financial investor rather than an operational manager.

Issuing New Shares After Formation

A company can issue new shares at any time after its incorporation, a process known as 'allotment'. This is the primary way to bring in new shareholders, such as investors, or to change the ownership percentages among existing members. The power to allot new shares typically rests with the directors, but this authority must be granted by the shareholders, either through a provision in the articles of association or by passing an ordinary resolution. A critical legal concept here is 'pre-emption rights', established by the Companies Act 2006. These rights give existing shareholders the first opportunity to buy any new shares the company issues, in proportion to their current holding. This protects them from having their ownership stake unfairly diluted by the company issuing shares to outsiders.

The pre-emption process can be administratively complex, so for many private companies, these rights are 'disapplied' or excluded in their articles of association from the outset. Alternatively, shareholders can waive their pre-emption rights for a specific share issue by passing a special resolution (requiring a 75% majority vote). Once the legal authority is in place, the directors can formally allot the new shares to the intended person(s) at an agreed price (which must be at least the nominal value). The new shareholder pays the company for the shares, and the company's statutory records, particularly the register of members, must be updated immediately. Finally, the company has a legal duty to report the change to Companies House by filing a Form SH01 (Return of allotment of shares) within one month of the allotment.

Worth knowing: Issuing new shares is a formal process requiring director authority, consideration of pre-emption rights, and filing with Companies House.

Paying for Shares: Cash vs. Non-Cash Consideration

Shares in a limited company are not free; they must be paid for with either money or 'money's worth'. This payment is known as 'consideration'. The simplest form is cash. When a shareholder subscribes for 100 shares at a nominal value of £1 each, they owe the company £100. They can pay this by transferring funds to the company's business bank account. The shares are then 'fully paid-up'. Alternatively, a company can issue shares in return for non-cash consideration. This involves a shareholder transferring a non-monetary asset to the company in exchange for an agreed value of shares. Common examples include providing equipment (laptops, machinery), intellectual property (software code, a brand name), or even services.

While non-cash consideration is a useful tool, it requires careful handling. The directors have a duty to determine the fair value of the asset being transferred to the company. If they agree to issue £5,000 worth of shares in exchange for a piece of software, they must genuinely believe the software is worth £5,000. Overvaluing a non-cash asset can have serious consequences. If the asset is later found to be worth less, the shareholder can be held liable to pay the difference in cash. For private companies, there's no legal requirement for an independent valuation (unlike public companies), but obtaining one is prudent for high-value transfers to protect the directors and justify the transaction. The agreement to exchange the asset for shares should be clearly documented in a written contract and approved in a board minute.

Worth knowing: Shares must be paid for in cash or a fairly valued non-cash asset, with the valuation being a key director responsibility.

Share Capital and Tax Implications

The way you structure your share capital has several tax consequences for both the company and its shareholders. The company pays Corporation Tax on its profits before any dividends are distributed. The current main rate is 25% for profits over £250,000, with a small profits rate of 19% for profits up to £50,000 and marginal relief in between. Dividends are paid from these post-tax profits. For the shareholder receiving the dividend, it is treated as personal income and is subject to dividend tax. Each individual has a tax-free Dividend Allowance, and amounts above this are taxed at different rates depending on their income tax band. Using flexible Alphabet shares to issue dividends can help manage the overall tax burden for a group of shareholders, but must be done for genuine commercial reasons.

When a shareholder disposes of their shares—by selling them, gifting them, or upon the company's closure—any profit they make is potentially subject to Capital Gains Tax (CGT). The 'gain' is the difference between the disposal proceeds and the initial cost of the shares (plus any associated costs). Every individual has an annual CGT exemption, and gains above this are taxed. The rate of CGT depends on the individual's income tax bracket. A significant relief for business owners is Business Asset Disposal Relief (BADR), formerly Entrepreneurs' Relief. If the qualifying conditions are met, it allows individuals to pay a reduced CGT rate of 14% for 2025/26 disposals, rising to 18% from 6 April 2026, on lifetime gains up to a certain limit. Finally, when shares are transferred between individuals for a price over £1,000, the buyer is liable for Stamp Duty, calculated at 0.5% of the consideration paid.

Worth knowing: Share transactions trigger tax events such as dividend tax on income, Capital Gains Tax on disposal, and Stamp Duty on transfers.

Legal and Administrative Duties

A UK company has a legal obligation under the Companies Act 2006 to maintain accurate and up-to-date records regarding its ownership. These are known as the company's 'statutory registers' and must be available for inspection. The most important register relating to share capital is the 'register of members'. This is the definitive record of who owns the company's shares. For each shareholder, it must contain their name and address, the number and class of shares they hold, the date they became a member, and the date they ceased to be one. You must also maintain records of all share allotments and transfers. Failure to maintain these registers correctly is an offence by the company and its directors.

Beyond internal records, you have a duty to keep Companies House informed of your share capital structure. This is done primarily through the annual confirmation statement. On this statement, you must confirm your 'statement of capital' is correct as of the review date. The statement of capital is a snapshot showing the total number of shares, their aggregate nominal value, and the details for each class of share. The 2025 digital filing fee for the confirmation statement is £50. If you have made changes during the year, such as issuing new shares, you must file the relevant forms (e.g., an SH01 for a new allotment) before or at the same time as your confirmation statement. Keeping these records immaculate prevents ownership disputes, simplifies due diligence if you seek investment or a sale, and ensures you remain compliant with the law.

• Maintain a Register of Members: The primary legal record of share ownership.
• Update Statutory Registers: Any change (new issue, transfer) must be recorded immediately.
• File a Confirmation Statement: Annually confirm your statement of capital with Companies House.
• File Event-Driven Forms: Submit Form SH01 for new share allotments within one month.
• Issue Share Certificates: Provide each shareholder with a certificate as prima facie evidence of their ownership.
• Keep Board Minutes: Document all decisions regarding share allotments or transfers in board meeting minutes.

Worth knowing: Meticulous record-keeping and timely reporting to Companies House for all share capital matters is a non-negotiable legal requirement.
