Can a Company Buy Shares? A Guide to Australian Rules

If you’re running a small business or startup, it’s normal to reach a point where you start thinking beyond day-to-day operations.

Maybe you’re looking to invest surplus cash, support a strategic partner, restructure your group, or even bring an investment vehicle “in-house” so you can hold shares through a company instead of personally.

That’s where the question comes up: can a company buy shares in Australia?

In most cases, yes. But “yes” doesn’t mean “no rules”. A company buying shares can raise practical, compliance and documentation issues - and if you get the structure wrong, you can create tax headaches, director duty issues, regulatory issues, or unintended control problems.

Below, we’ll walk through what you need to know as a business owner, including common reasons companies buy shares, the main legal and governance considerations, and the documents you’ll want in place.

Can a Company Buy Shares in Australia?

Generally, a company can buy shares in Australia.

Australian companies are separate legal entities, which means they can usually own assets in their own name - including shares in other companies (whether private companies or public companies).

That said, whether your company should buy shares, and whether it can buy shares in a particular situation, depends on things like:

• your company’s constitution and any shareholder agreements
• the directors’ duties and whether the purchase is in the best interests of the company
• how the purchase is funded (company cash, loan, related party funding)
• whether you’re buying shares in your own company (a buy-back) or another company
• whether any third-party consents are required (for example, lender consents)
• the rules in the target company (such as restrictions on share transfers)
• whether any related party rules apply (for example, public company financial assistance rules, or related party benefit approvals)
• whether any foreign investment approvals may be required (for example, FIRB in some circumstances)

It’s also worth separating two common scenarios that get mixed up:

• Your company buys shares in another company (an investment or acquisition).
• Your company buys back its own shares (a “share buy-back”, which has extra rules and process requirements).

This article focuses mainly on the first scenario (company buying shares in another company), but we’ll also flag the buy-back angle so you don’t accidentally apply the wrong approach.

Why Would a Small Business or Startup Buy Shares Through a Company?

There are plenty of legitimate, commercial reasons you might want your company (not you personally) to hold shares.

Here are some common examples we see for small businesses and startups.

1. Investing Surplus Profits

If your business is generating steady profits, you might use the company to invest some of that cash into shares (for example, long-term growth investments).

This can be part of a broader business strategy - but it still needs to be a decision made properly by directors, with clear records about why it’s in the company’s interests.

2. Strategic Investments and Partnerships

Sometimes buying shares isn’t about “investing” so much as building commercial relationships.

For example, you might buy a stake in:

• a supplier (to secure supply or influence quality)
• a distributor or channel partner (to secure routes to market)
• a complementary business (to collaborate on product or growth)

In these cases, the legal documents matter even more, because your shareholding will often come with expectations around governance, information rights, and exit options.

3. Group Structuring (Holding Company / Subsidiary)

As you grow, you might create a group structure where one company holds shares in another (for asset protection, governance, or future capital raising).

For example, you might set up a parent company that holds shares in an operating company.

When you’re structuring a group like this, it’s worth thinking carefully about share rights and control (including different classes of shares), as well as your governance documents like a Company Constitution.

4. Making It Easier to Bring in Investors Later

If you’re a startup that expects to raise capital, there can be scenarios where it’s cleaner for an entity to hold shares (for example, a corporate vehicle used by founders, or a corporate trustee for a trust structure).

But “cleaner” depends heavily on your cap table, shareholder agreements, and the expectations of future investors - so it’s worth getting advice early before your structure becomes hard to unwind.

Key Legal Checks Before Your Company Buys Shares

Even though the short answer is usually “yes”, the legal work is in making sure the purchase is properly authorised and properly documented.

Here are the main checks to run before committing.

1. Does Your Company Have Power to Make the Investment?

Most companies have broad power to do business and hold assets. But you should still check your internal governance documents, including:

• your constitution (if your company has one)
• any shareholders agreement that restricts major decisions
• any board or shareholder approval thresholds you’ve adopted

If your company’s constitution or shareholders agreement requires approvals (for example, a special resolution for major investments), you’ll want to follow that process before signing anything.

2. Directors Must Act in the Best Interests of the Company

When a company buys shares, it’s the company taking on the risk - not the directors personally (in most situations).

That’s why directors need to be able to show that:

• the decision was properly considered
• there was a genuine business purpose (not just a personal benefit to a director or shareholder)
• any conflicts were disclosed and managed
• the company can afford it and isn’t being put at unreasonable risk (including solvency considerations)

A practical way to support this is to prepare board minutes or a directors’ resolution documenting the reasons for the purchase and the key terms.

If you need a starting point, a Directors Resolution Template can help you capture the decision-making properly.

3. Check the Target Company’s Share Transfer Rules

If you’re buying shares in a private company (especially a small proprietary company), you can’t assume shares are freely transferable.

Common restrictions include:

• pre-emptive rights (existing shareholders get first chance to buy)
• director approval requirements
• limits on transferring shares to competitors
• requirements to sign a deed of accession to an existing shareholders agreement

Make sure you get and review:

• the target company’s constitution (if any)
• any shareholders agreement
• the share register and cap table (so you can confirm what you’re actually buying)

4. Be Clear About Whether You’re Buying New Shares or Existing Shares

From a practical perspective, you’ll usually be doing one of the following:

• Subscription: your company buys newly issued shares directly from the target company (often used for investment rounds).
• Transfer: your company buys shares from an existing shareholder (often used for founder exits or secondary sales).

These deal types often use different documents and have different approval steps.

For example, a subscription commonly involves a share subscription agreement and board approvals for the share issue, while a transfer often involves a share sale agreement, a share transfer form, and updates to the register.

5. Consider Whether Any Consents Are Needed

Even if the transaction is allowed, you may need third-party consents depending on your circumstances, such as:

• your bank (if you have loan covenants restricting investments or asset disposals)
• other shareholders (if your shareholders agreement requires it)
• the target company’s board
• regulatory approvals (for example, FIRB where required)

It’s much easier to confirm this upfront than to negotiate after you’ve already agreed on commercial terms.

6. Watch for Related Party and “Financial Assistance” Issues (If Relevant)

Some transactions raise extra legal issues even if they look straightforward commercially.

• Related party transactions: if the deal involves a director, shareholder, or their associates, additional approvals and careful process may be needed to manage conflicts and (in some cases) comply with related party benefit rules (especially for public companies and entities with public company connections).
• Financial assistance: if a company is giving financial assistance to help someone buy shares in itself (or its holding company), there are specific Corporations Act restrictions and approval processes that can apply (this often comes up in group restructures and leveraged acquisitions).

These issues don’t apply to every small business share purchase, but they’re important to flag early because they can change the required steps and documents.

How a Company Buys Shares: The Practical Process

If you’re approaching this as a small business owner, the process is usually manageable if you break it down into steps.

Step 1: Confirm the Commercial Deal

Start by confirming what you’re actually buying and on what terms, including:

• number and class of shares
• purchase price and payment timing
• any warranties (promises) from the seller or target company
• conditions precedent (for example, approvals or due diligence)
• completion mechanics (when ownership changes and what documents get signed)

For early-stage deals, parties sometimes start with a term sheet or short heads of agreement so everyone is aligned before spending time on full documents.

Step 2: Get the Right Internal Approvals

Before signing, your company should approve the investment properly (usually via board approval, and sometimes shareholder approval).

This is where having a clear governance trail helps. If things go wrong later, your records show that the decision was considered and authorised.

Step 3: Sign the Share Purchase Documents

Depending on the transaction, key documents can include:

• a share sale agreement (for a transfer)
• a share subscription agreement (for a new issue)
• a shareholders agreement (or deed of accession to an existing one)
• board minutes and shareholder resolutions (as required)

If you’re buying into a private company with multiple owners, a Shareholders Agreement is often one of the most important documents, because it sets out decision-making, deadlock processes, transfer restrictions, and exit rights.

Step 4: Complete the Transfer and Update the Registers

After completion, the target company should update its records to show your company as the shareholder.

This often involves:

• updating the share register
• issuing a share certificate (if the company uses them)
• updating any internal governance records

If you’re not sure what to expect here, it helps to understand how share certificates work in practice (and when they matter).

Step 5: Keep Ongoing Governance in Mind

Once your company holds shares, you’ll need to manage the shareholder relationship on an ongoing basis.

That may include:

• receiving shareholder notices and voting on resolutions
• participating in capital raises (or dealing with dilution)
• reviewing financial information and reports (if you have rights to them)
• ensuring your company’s accounting and tax reporting is handled properly

What Legal Documents Might You Need?

The documents you need will depend on whether your company is investing as a minority shareholder, taking a controlling stake, or doing something strategic.

As a general guide, here are common documents to consider.

• Share Sale Agreement: records the key commercial and legal terms when your company buys shares from an existing shareholder.
• Share Subscription Agreement: used when your company subscribes for newly issued shares directly from the target company.
• Shareholders Agreement: sets out how the company is governed, how decisions are made, and what happens if someone wants to exit or there’s a dispute.
• Company Constitution: can regulate share transfers, rights attached to shares, and internal decision-making; it’s often read together with a shareholders agreement.
• Board Minutes / Director Resolutions: evidence that your directors properly approved the purchase (and considered their duties).
• Confidentiality Agreement (NDA): useful if you’re receiving sensitive information during negotiations or due diligence.

Depending on the deal, you may also need additional documents (for example, side letters for information rights, option agreements, or financing documents if you’re borrowing to fund the purchase).

Common Traps and Practical Tips for Business Owners

Company share purchases are usually very doable for small businesses - but there are a few common pitfalls worth watching out for.

Mixing Up Company Investing vs Buying Back Your Own Shares

If your company is buying shares in itself, that’s a different legal process (a share buy-back) with additional Corporations Act requirements.

So before you proceed, confirm which of these applies:

• your company is investing in another business (standard purchase/subscription process), or
• your company is reducing its own shareholder base (share buy-back process).

Buy-backs can be structured in different ways (for example, equal access, selective, on-market and employee share scheme buy-backs), and the right process depends on the type, your constitution, shareholder approvals, ASIC notifications, and solvency requirements.

Not Documenting the Decision Properly

One of the most avoidable risks is failing to properly document the directors’ decision-making.

Even if you’re a small company with a single director, it’s worth preparing a short resolution that confirms:

• what shares are being purchased
• the price and key terms
• why it’s in the company’s best interests
• how any conflicts were managed

This is especially important if the purchase is related-party connected (for example, buying shares from a director or someone close to them).

Ignoring Funding and Solvency Issues

If the company is funding the purchase via a loan (particularly where a bank or private lender is involved), you should check whether the lender needs consent, security over company assets, or imposes restrictions on investments.

You’ll also want to ensure the company can afford the investment without putting itself at financial risk (including being able to pay its debts as and when they fall due).

Assuming Minority Shareholdings Give You Control

Buying shares does not automatically mean you can “call the shots”.

Unless you’re buying a controlling stake, your influence will depend heavily on:

• the class of shares you hold (voting rights, dividend rights, etc.)
• the constitution and shareholders agreement
• any negotiated rights (like board seats or veto rights)

So if your business goal is strategic control (not just financial upside), make sure the rights match the commercial intent.

Overlooking Tax and Accounting Outcomes

How your company buys, holds and sells shares can have different tax and accounting outcomes depending on your structure and the purpose of the investment (for example, revenue vs capital treatment, franking implications on distributions, and how gains/losses are treated).

This article is general information and not tax or financial advice - it’s a good idea to speak with your accountant or tax adviser before you commit to a structure.

Key Takeaways

• In most cases, Australian companies can buy and hold shares, but the transaction still needs to be properly authorised and documented.
• Before your company buys shares, check your constitution, any shareholders agreement, and whether director or shareholder approvals are required.
• Directors should document why the purchase is in the company’s best interests and manage any conflicts of interest carefully.
• Private company share purchases often involve transfer restrictions, consents, and governance documents, so don’t assume it’s as simple as “pay and you’re in”.
• Depending on the structure, extra rules may apply (for example, related party approvals, financial assistance restrictions, and foreign investment approvals such as FIRB).
• The right documents (like a share sale agreement and shareholders agreement) can reduce disputes and clarify control, exits, and decision-making.
