Registering a company is not only a naming and paperwork exercise. Before the application goes in, you decide how many shares the company will have, what class they belong to, who holds them and how much of each share is paid. Those choices set out who owns the business, who controls it and what records you will be maintaining for as long as the company exists.
This guide walks through share classes, who can be a shareholder, what ASIC records at registration and what the company has to keep in its own register. It separates what the official sources state, how that plays out in practice, and what you should confirm for your own circumstances before you lodge anything.
What a share actually gives you
A company is a business structure in which business operations are controlled by directors and owned by the shareholders, according to business.gov.au. That split is the point of the structure, and it is worth understanding before you allocate anything.
ASIC's guidance on company shares and shareholders is direct about what ownership does and does not mean:
- Shareholders do not own the company's assets, and they are not responsible for the day-to-day running of the company.
- For most companies, shareholders can access some company information and vote on some company decisions.
- Your only financial obligation is to pay the company any amount unpaid on your shares if you are called on to do so.
The third point is the practical definition of limited liability in a company with share capital. If your shares are fully paid, there is nothing further to contribute. If they are issued partly paid, the company can call on the unpaid amount, and that is the exposure you carry. Deciding at registration whether shares will be fully paid or partly paid is therefore not a formality.
Practical reading: because owners do not run the business, a decision that changes ownership and a decision that changes management are two different decisions. Founders often assume a handshake covers both. It usually does not.
Choosing a share class
A share class is simply a group of shares carrying the same set of rights. Everyone in the same class is treated the same way; different classes exist so that different holders can be treated differently.
The simple option. A single class of ordinary shares is the most straightforward structure for a small, closely held company. One class means one set of rights, one set of records and fewer decisions to revisit later.
Why people add a second class. Companies with more than one class usually do it to vary voting rights, dividend entitlements, or the order in which capital is returned. It is a structure often considered when bringing in outside investors, setting aside equity for employees, or giving a non-executive contributor an economic interest without equivalent voting power.
What complexity costs. Each additional class multiplies the record-keeping. Every issue, transfer, conversion or cancellation has to be recorded by class, and the company's register has to be kept up to date. ASIC also expects to be told about changes to shares and shareholders.
This is an area where the supplied official material does not set out the mechanics of particular classes. Treat any specific rights as a design decision you confirm against your company's governing rules and with a suitably qualified adviser, not as something the registration form decides for you.
Who can be a shareholder
ASIC records details of the company's shareholders when it is registered, and those details are the public-facing record of ownership. Shareholders can be the same people as the directors, which is normal in small companies, or a different group entirely.
There are two things to be careful about here, because they are commonly assumed and rarely checked:
- Eligibility and restrictions. Whether a particular person or entity can hold shares in your company, and whether your constitution restricts who may hold them, is a question to confirm with ASIC's guidance or your registered agent before you rely on the arrangement. Do not infer it from what another company did.
- Joint and nominee holdings. How a share is held — in your own name, jointly, or on behalf of someone else — affects what goes on the register and what ASIC records. Confirm the correct treatment for your situation rather than guessing at the form.
If your intended ownership includes minors, overseas residents, trusts or other companies, put that in the "verify first" list rather than the "assume" list.
What ASIC records when you register
When you set up a company that issues shares, it will have shareholders and a share capital. At registration, ASIC's record captures the fundamentals of that structure and the people attached to it: the share structure you have chosen, and the details of each shareholder and officeholder.
In practice, that means the registration is where your share decisions become a matter of public record. Two consequences follow:
- Errors are visible. A share split recorded incorrectly at registration is not a private paperwork problem. It sits on the public record until it is corrected.
- The register is not the whole agreement. ASIC's record shows what has been reported. It does not settle commercial understandings between founders about vesting, buy-backs, what happens when someone leaves, or how disputes are resolved. Those belong in the company's governing rules or a separate agreement between shareholders.
Confirm the exact fields ASIC requires on its company shares and shareholders page before completing the application, so that the information you supply matches what you intend.
The company's own share register
Separate from what ASIC holds, the company must maintain its own record. ASIC states that details of the shares and shareholders must be kept up to date on the company's share register.
A usable register tracks, at minimum:
- each shareholder and the shares they hold, by class
- the amount paid and unpaid on those shares
- dates of issue, transfer or cancellation
- any change in a shareholder's details
Set it up on day one, not at the first annual review. The register is what you will rely on to work out who is entitled to vote, who is entitled to a distribution, and who needs to be notified when something changes. Because shareholders can access some company information, the register is also a document others may ask to see — check ASIC's guidance and your company's governing rules for who may inspect it and on what terms.
Two clocks you need to manage
| Obligation | What it covers | Timing | Source |
|---|---|---|---|
| Notify ASIC of changes | Changes to shares and shareholders | ASIC asks companies to update it within 28 days of a change — confirm the exact timing for each change type on ASIC's site | ASIC |
| Keep the share register current | All share and shareholder details | Ongoing, at the time of each change | ASIC |
| Lodge a company tax return | Annual return to the Australian Taxation Office (ATO) | Annually | business.gov.au |
The point of the table is that these are separate jobs. Updating ASIC does not update your register, and updating your register does not tell ASIC. Both have to happen.
Questions to verify before you register
Work through this list while you can still change the answers cheaply:
- How many shares will the company have, and at what issue price?
- Will shares be fully paid or partly paid, and can you meet a call if one is made?
- Is one class of ordinary shares enough, or do you need different rights for different holders?
- Who holds what, and does that split reflect what each person is contributing?
- Are the same people both directors and shareholders, and is that intended?
- Which rules govern the company — a constitution, or the default rules that apply otherwise?
- Who maintains the share register, and how will a change get onto it within 28 days?
- Does the business need any licence or registration? Check requirements through the Australian Business Licence and Information Service.
Next steps
- Write down the intended structure — number of shares, class, issue price, paid or unpaid, and each holder's allocation — before opening the registration form.
- Read ASIC's company shares and shareholders page and confirm the fields and change-notification timeframes that apply to you.
- Create the share register at the same time as you register the company, and record the first issue of shares in it.
- Diary a reminder for any change: update the register, then notify ASIC.
- Confirm the company's tax obligations, including the annual company tax return lodged with the ATO, with a registered tax agent.
- Get advice from a lawyer or accountant licensed to give it before settling share rights, a constitution or a shareholders' agreement.
