Bonus Issues in the UK: A Guide for Companies and Shareholders

A bonus issue can look simple on paper: the company gives existing shareholders extra shares for free, usually in proportion to what they already hold. In practice, this is where directors and founders often get caught. Common mistakes include treating a bonus issue like a cash dividend, failing to check the company’s articles or shareholder arrangements, and filing the wrong forms or records after the allotment. Another frequent problem is assuming there is no legal process because no money changes hands.

For UK companies, a bonus issue still needs proper corporate housekeeping. You need to understand where the shares are coming from, whether you have authority to allot them, what happens to pre-emption rights, and how to update your company records. Shareholders also need to know what a bonus issue does, and does not do, to their value and voting position. This guide explains what a bonus issue means, when businesses use one, the practical steps to handle it properly, and the mistakes worth avoiding before you sign resolutions or update your cap table.

Overview

A bonus issue is an allotment of additional shares to existing shareholders without asking them to pay cash for those new shares. It is usually made pro rata, so each shareholder receives extra shares in line with their current holdings, which means ownership percentages often stay the same.

Although it can be a useful way to reorganise share capital, it is still a formal company law step. Directors should make sure the company has the legal authority, the right reserves or capital structure, and clear internal approvals before proceeding.

• Check the company’s articles of association and any shareholders’ agreement for restrictions or approval requirements.
• Confirm directors have authority to allot the shares and consider whether statutory pre-emption rights apply or are disapplied.
• Work out the source for the issue, such as distributable profits or other reserves that can be capitalised.
• Approve the bonus issue properly with board minutes and, where needed, shareholder resolutions.
• Update the register of members, issue share certificates if appropriate, and make any Companies House filings on time.
• Review the impact on investor rights, employee share schemes, valuation discussions, and future fundraising documents.

What Bonus Issue Means For UK Businesses

A bonus issue increases the number of shares in issue by giving existing shareholders new shares for no payment, but it does not usually change the overall economic value of the company. It is often described as capitalising reserves and converting part of the company’s accumulated value into share capital.

For many founders, the key point is this: a bonus issue changes the company’s share structure, not the size of the business itself. If everyone receives shares in the same proportion, each shareholder’s percentage holding will usually remain the same.

What Is A Bonus Issue?

A bonus issue, sometimes called a scrip issue or capitalisation issue, is where a company allots fully paid shares to existing shareholders for free. The shares are usually issued in a set ratio, such as one new share for every five already held.

This is different from a new investment round. In a fundraising, shareholders or investors pay for new shares. In a bonus issue, no new cash comes into the business.

Why Would A Company Make A Bonus Issue?

Companies use bonus issues for a few practical reasons. Sometimes the business wants to increase the number of shares in circulation to make the share capital easier to work with. In other cases, the company wants to convert reserves into share capital for accounting or balance sheet reasons.

A bonus issue can also arise before a reorganisation, an investment round, a group restructure, or an employee incentive plan. For example, a company with a very small number of high-value ordinary shares may want a larger share base before offering options or bringing in external investors.

Founders sometimes use a bonus issue to create cleaner numbers. A company with 100 shares in issue might decide it would be easier to manage future transactions if it had 10,000 shares instead. That may sound administrative, but it still needs to be documented properly.

How Is It Different From A Share Split Or Dividend?

This is where confusion often starts. A bonus issue is not the same as a share split, and it is not simply a dividend paid in shares.

• A share split changes the nominal structure of existing shares, for example turning one £1 share into ten 10p shares.
• A bonus issue creates additional shares and allots them to shareholders.
• A cash dividend distributes money to shareholders.
• A dividend in specie or scrip dividend can have separate legal and tax considerations and should not be treated as automatically interchangeable with a bonus issue.

The legal mechanics matter. If a business picks the wrong process because the outcomes look similar in commercial terms, its records can become inconsistent with what was actually approved.

Why Does This Matter To Shareholders?

Shareholders usually want to know whether a bonus issue dilutes them. If the issue is made equally and proportionately to all holders of the relevant class, the answer is usually no. Each shareholder receives more shares, but their percentage stake generally stays the same.

That said, the detail matters. If there are different share classes, unpaid shares, option holders, convertible instruments, or bespoke rights in the articles or shareholders’ agreement, a bonus issue can affect rights in less obvious ways. It may also change how future consents, dividend calculations, or drag and tag provisions work if those clauses depend on share numbers rather than percentages.

When This Issue Comes Up

A bonus issue usually comes up when a company is tidying its capital structure before a wider business step. Founders often first hear about it during investment prep, a corporate reorganisation, or when formalising records that were left too loose in the early stages of company setup.

Before An Investment Round

Investors often want a clear and consistent cap table. If the company has a very small number of issued shares, awkward nominal values, or legacy shareholdings that make pricing difficult, a bonus issue may be considered before the round.

This can help make the share structure easier to explain in term sheets, subscription documents and board approvals. It can also make option pool calculations more practical.

The main risk is rushing the process to meet a deal timetable. Before you sign investment documents, make sure the pre-round bonus issue has actually been validly approved and recorded.

Before Setting Up An Employee Share Scheme

If the business plans to grant options or create a more flexible employee equity structure, a bonus issue may be part of the groundwork. A larger pool of shares can make percentages, exercise pricing and grant sizes easier to administer.

That does not mean a bonus issue is always the right first step. The company should check how the new shares interact with any existing option plan, growth shares, EMI arrangements, or leaver provisions. Founders often assume these documents will adjust automatically, but many do not.

During A Group Reorganisation

Bonus issues also appear in restructures, especially where a company wants to align share capital with a new holding structure or internal reallocation. In these situations, the legal paperwork around class rights, reserves, accounting treatment and filings becomes more important.

This is where SMEs can run into trouble if they copy an old precedent without checking whether the company’s articles and actual share classes match the document.

When Historic Company Records Need Cleaning Up

Sometimes the issue comes up because someone discovers the company records are inconsistent. The board may have intended one capital change years ago, but the statutory books show something else. A bonus issue then becomes part of a broader cap table clean-up and corporate record review.

That sort of tidy-up should be handled carefully. If records are missing, inconsistent, or suggest earlier allotments were not properly approved, the company may need to fix historic corporate paperwork before making any new issue.

In Mature Private Companies As A Capital Management Tool

Established private companies sometimes use bonus issues to convert accumulated reserves into issued share capital. This can be part of a wider strategy around balance sheet presentation or internal shareholder arrangements.

Even then, directors should avoid treating it as a purely accounting exercise. A bonus issue is still a legal event affecting the company’s capital and shareholder records.

Practical Steps And Common Mistakes

The safest approach is to treat a bonus issue like any other formal share allotment and work through authority, approvals, documents and filings in order. Most problems happen when companies jump straight to updating the cap table without checking the legal basis first.

1. Review The Articles And Any Shareholders’ Agreement

The company’s constitution comes first. The articles may contain rules on allotment powers, class rights, share certificate timing, and procedures for shareholder decisions. A shareholders’ agreement may add consent rights or restrictions, especially where investors are involved.

Check documents for points such as:

• whether directors already have authority to allot shares, or whether shareholder approval is needed
• whether there are different share classes with special rights
• whether any investor consent or founder consent is required
• whether pre-emption rights are dealt with
• whether there are provisions affecting employee options or convertibles

A common mistake is relying only on the model articles without checking whether the company adopted amended articles during a previous funding round.

2. Confirm The Legal Basis For The Bonus Issue

A bonus issue is generally made by capitalising available reserves or other sums that the company is permitted to apply for this purpose. The exact route depends on the company’s circumstances, including its articles and accounts.

This is not an area for guesswork. Directors should understand what reserve or amount is being capitalised and whether the issue is of fully paid shares. If the accounting treatment is unclear, legal and accounting input should line up before resolutions are signed.

Founders often assume that because the shares are “free”, there is no consideration issue to think about. In reality, the company still needs a valid legal and accounting basis for issuing them as fully paid.

3. Check Allotment Authority And Pre-emption Rights

Private companies often need to consider the directors’ authority to allot shares under the Companies Act 2006 and whether statutory pre-emption rights apply. A bonus issue may be structured in a way that falls outside the commercial concern about dilution, but that does not mean you should ignore the legal analysis.

If the shares are being allotted only to existing shareholders pro rata, the practical concern about unfairness may be low. Even so, the company should still check whether a formal disapplication of pre-emption rights is required or whether the articles already deal with this point.

This is one of the most common technical mistakes in founder-led businesses. The result is often a cap table that looks fine commercially but sits on shaky legal paperwork.

4. Approve The Issue Properly

A bonus issue should be approved through the right internal decision-making steps. That usually means board minutes, and in some cases shareholder resolutions as well.

The written records should cover:

• the reason for the issue
• the ratio or number of shares to be issued
• the class of shares being allotted
• the authority relied on for allotment
• the treatment of reserves or capitalised amounts
• any updates to certificates, registers and Companies House filings

Before you sign resolutions, make sure the names, share numbers, dates and class rights all match the current statutory books. Small drafting mistakes can create larger problems when due diligence starts later.

5. Update Statutory Registers And File What Is Required

Once the bonus issue is approved and takes effect, the company needs to update its internal records. This usually includes the register of members and, where relevant, issuing new or replacement share certificates.

Companies House filings may also be required, such as a return of allotment. The timing and content matter. If the company misses a filing deadline or files inaccurate numbers, that can complicate future funding, exits and compliance reviews.

Businesses often focus on the filing and forget the statutory books. Both matter. A Companies House record is not a substitute for accurate internal registers.

6. Check The Wider Documents That May Need Updating

A bonus issue can have knock-on effects across your company documents. After the allotment, review whether any of the following need to be updated:

• the cap table used in investor updates and board packs
• shareholders’ agreement schedules
• option plan limits and grant templates
• vesting documents for founders or employees
• articles references to issued share capital or class rights
• subscription or investment documents being prepared for a transaction

This is where founders often get caught. The bonus issue itself may be valid, but old schedules and side documents continue showing outdated share numbers.

7. Communicate Clearly With Shareholders

Shareholders do not always object to a bonus issue, but they often misunderstand it. Some think they are receiving extra value. Others worry they are being diluted because the number of shares has increased.

A short explanatory note can help. It should explain what the issue does, the ratio used, whether percentages change, and when updated certificates or statements will be available.

That is especially helpful where the company has passive investors who are not involved in day-to-day management.

Common Mistakes To Avoid

The same errors come up again and again in SMEs:

• using the phrase “bonus issue” when the company actually means a share split or dividend
• ignoring the articles and shareholders’ agreement
• assuming no approvals are needed because no money is paid
• forgetting to analyse allotment authority and pre-emption rights
• recording the wrong nominal values or share classes
• failing to align legal documents with accounting treatment
• updating Companies House but not the statutory registers, or the other way around
• making the change just before a funding round without enough time for a proper contract review and to fix errors

If your company has multiple share classes, unpaid shares, convertible instruments, or historic filing issues, a bonus issue deserves extra care. Those features can turn a simple pro rata issue into a more technical restructuring step.

FAQs

Does a bonus issue change ownership percentages?

Usually not, if all relevant shareholders receive new shares in the same proportion. Ownership percentages can change if the issue is not fully pro rata, if different classes are treated differently, or if other rights are triggered.

Do private companies in the UK need to file anything for a bonus issue?

Often yes. A return of allotment may be required, and the company should update its statutory registers and share certificates where appropriate. The exact filing position depends on the structure of the issue.

Is a bonus issue the same as free shares for tax purposes?

Not necessarily. The company law steps and the tax treatment are separate questions. Businesses should avoid assuming the legal label answers the tax position.

Can directors approve a bonus issue on their own?

Sometimes, but only if the company’s constitution and the Companies Act position allow it. Many companies need to check shareholder authority, allotment powers, and any investor consent rights first.

What is the difference between a bonus issue and a share split?

A share split changes the denomination or number of existing shares. A bonus issue creates and allots new shares. They can produce similar headline numbers, but the legal process is different.

Key Takeaways

• A bonus issue gives existing shareholders additional shares for no cash payment, usually in proportion to current holdings.
• It does not usually change the overall value of the company or dilute holders if done pro rata across the relevant class.
• UK companies should check their articles, shareholders’ agreement, allotment authority, pre-emption rights, and the source of any capitalised reserves before proceeding.
• Proper board approvals, shareholder resolutions where required, statutory register updates, and Companies House filings are essential.
• The process is often used before investment rounds, employee share arrangements, restructures, or cap table clean-ups.
• The main risks are using the wrong legal mechanism, skipping approvals, and leaving company records inconsistent.
