Share Splits in Australia

A share split (also called a subdivision of shares) is a relatively simple but powerful corporate tool used by Australian companies to restructure their share capital without changing ownership percentages. While commonly associated with listed companies, private and growing businesses can also benefit from share splits particularly when preparing for investment, employee equity, or scaling operations.

What is a Share Split?

A share split increases the number of shares on issue by dividing existing into a larger number, while proportionally reducing the value of each individual share. Importantly, the overall value of the company remains changed.

For example, in a 2-for-1 split:

  • Each shareholder receives two shares for every one previously held

  • The value per share halves

  • Total ownership percentage stays the same

This means a shareholder with 10% ownership before the split will still hold 10% afterwards.

Why Do Companies Use Share Splits?

Although a share split doesn’t change underlying value, it can play a strategic role in corporate growth.

  1. Improve affordability and accessibility
    If a company’s share price is relatively high, splitting shares reduces the cost per share, making them more attractive and accessible to investors.

  2. Prepare for investment or fundraising
    Startups and scaling companies often use splits to create a more flexible capital structure that aligns with investor expectations or future funding rounds.  A minimum number of shares is often required to create a desired capital table.

  3. Enable employee equity schemes
    A larger number of shares allows companies to issue smaller, more precise equity packages under Employee Share Option Plans (ESOPs).

  4. Improve liquidity and trading flexibility

    More shares on issue can make trading easier and increase overall activity, which may enhance investor interest.

  5. Avoid dilution compared to issuing new shares

    Unlike issuing new shares, a split does not dilute existing shareholders’ ownership.

Share Split vs Other Corporate Actions

It’s important to distinguish a share split from similar actions:

  • Share Split; increases number of shares; no ownership change; decreases per-share value (but not overall company value)

  • Share consolidation (reverse split): reduces number of shares; no ownership change; increases per share value (but not overall company value)

  • Issuing new shares; increases number of shares; dilutes ownership where issue is to incoming party or not issued proportionally to existing shareholders

Each serves a different purpose, so companies should align the method with their strategic goals.

Legal and Tax Considerations in Australia

No Immediate CGT event

A standard share split generally does not trigger capital gains tax (CGT), as it is treated as a reorganisation rather than a disposal of shares.

Instead

  • The original cost base is spread across the new shares

  • The original acquisition date still applies (important for CGT discounts)

Governance and Documentation

Before proceeding, companies should review:

  • Company constitution

  • Shareholders agreement

  • Any existing equity instruments

Adjustments may be required to ensure rights and pricing mechanisms remain consistent after the split.

Compliance obligations

Australian companies must ensure:

  • Proper resolutions are passed

  • Registers are updated

  • ASIC is notified within 28 days of the change

Failure to follow these steps may result in compliance issues or penalties.

How to Complete a Share Split (Step-by-Step)

While the process is generally straightforward, it must be handled carefully:

  1. Check governing documents
    Confirm your constitution and shareholder agreements allow for a share split and identify required approvals.

  2. Decide the split ratio
    Choose a ratio based on desired capital table flexibility

  3. Obtain approvals
    Shareholders typically approve the split via a circular resolution; or a resolution at a general meeting

  4. Update company records
    This includes register of members and share certificates (if used)

  5. Adjust related instruments
    Update option plans, convertibles, and other equity-linked arrangements so the economics remain unchanged

  6. Notify ASIC
    Lodge the relevant forms within 28 days of the split taking effect.

When Should You Consider a Share Split?

A share split is particularly useful when:

  • Your company started with a very small number of shares

  • You’re implementing an ESOP

  • You’re preparing for external investment

  • Your share structure lacks flexibility for future transactions
