Company Director Duties in Australia: What Every Small Business Owner Needs to Know

If you run a business through a proprietary company — a Pty Ltd — you are a company director. That title comes with serious legal obligations that most small business owners underestimate.

The Corporations Act 2001 imposes duties on every director of an Australian company. Breaching them can result in civil penalties of up to $1.565 million per contravention, criminal prosecution, and personal liability for company debts. These are not theoretical risks. ASIC pursues directors of small businesses, not just large corporations.

This guide covers what every small business owner-director needs to understand about their obligations under Australian law.

Why Director Duties Matter for Small Business Owners

Many small business owners treat their company as interchangeable with themselves. The company pays their mortgage, their car, their phone. They move money between accounts without thinking twice. They miss an ASIC filing deadline because they didn't know about it.

This is where things go wrong.

A company is a separate legal entity. As its director, you have duties to the company itself — not just to yourself as the owner. Breaching those duties can expose you to personal liability even when the company is the one that suffers the loss.

For sole director/sole shareholder companies (the most common structure for Australian SMBs), this distinction feels abstract — until a creditor sues, the ATO comes calling, or ASIC investigates.

The Five Core Director Duties

1. Duty of Care and Diligence

Under section 180 of the Corporations Act, you must exercise the degree of care and diligence that a reasonable person would exercise in the same position.

In practical terms, this means:

• Making informed decisions, not gut-feel ones
• Taking appropriate professional advice when needed
• Staying informed about your company's financial position
• Attending to compliance obligations — not leaving everything to your accountant and hoping for the best

The standard is objective: what would a reasonable person do in your position, given the nature of your company and your responsibilities?

This duty is enforced through ASIC's civil penalty provisions. Breaches can result in penalties of up to $1.565 million or disqualification from managing corporations.

2. Duty to Act in Good Faith

Section 181 requires directors to act in good faith in the best interests of the company, and for a proper purpose.

For owner-managed businesses, this duty is most commonly breached when a director:

• Pays themselves an unreasonable salary that depletes the company and harms creditors
• Makes decisions that benefit themselves personally at the company's expense
• Enters transactions with related parties (family, associated companies) on non-commercial terms

The good faith duty is not about intent — it's about whether your decisions genuinely served the company's best interests.

3. Duty Not to Improperly Use Position or Information

Sections 182 and 183 prohibit directors from using their position or information gained through their position to gain an advantage for themselves (or someone else), or to cause detriment to the company.

For small business owners, this often arises in situations like:

• Diverting business opportunities to a related entity
• Using company funds or assets for personal benefit without proper authorisation
• Taking key customer relationships or confidential information to a competing business

4. Duty to Avoid Conflicts of Interest

Directors must disclose any material personal interests in matters affecting the company. If you are entering a transaction where you personally stand to benefit — or where a related party does — you generally cannot vote on that decision and must disclose the interest to other directors (or, in a sole director company, manage the conflict carefully with proper documentation).

This is particularly relevant when a director:

• Leases premises to their company from a trust or family entity they control
• Engages a related business for services
• Receives a commission or referral fee related to a company transaction

5. Duty to Prevent Insolvent Trading

This is the duty that most directly terrifies small business owners — and with good reason.

Under section 588G of the Corporations Act, a director must not allow the company to incur a debt when the company is insolvent, or when incurring the debt would make the company insolvent.

If the company later goes into liquidation and a liquidator finds that debts were incurred while the company was insolvent — or ought to have been suspected to be insolvent — the director can be personally liable for those debts.

Signs of insolvency to watch for:

• Ongoing cash flow difficulties — unable to pay creditors on time
• Creditors demanding payment or issuing statutory demands
• ATO debt accumulating (particularly PAYG and superannuation)
• Bank refusing to extend facilities
• Inability to produce timely financial statements

If your company is experiencing any of these, take legal advice immediately. The safe harbour provisions (sections 588GA–588GF) may protect you if you are taking genuine steps to restructure — but only if you act promptly and with appropriate advice.

Director Identification Numbers (DIN)

From 5 April 2022, all directors of Australian companies are required to have a Director Identification Number (DIN).

A DIN is a unique identifier attached to you as an individual director — it follows you across every company you direct, and it helps ASIC track directors who might otherwise use phoenix company structures to avoid liability.

Who needs a DIN:

• All directors of companies registered under the Corporations Act
• Directors of registered foreign companies
• Directors of corporate trustees of self-managed superannuation funds

How to get one: Apply online through the Australian Business Registry Services (ABRS) at abrs.gov.au. The process requires myGovID at Standard or Strong identity strength.

Penalties for non-compliance: Failing to have a DIN when required, or providing false or misleading information when applying, can result in civil penalties up to $13,320 or criminal penalties including imprisonment.

If you became a director before the DIN requirement was introduced, you should already have one. If you are appointing a new director, they must apply for a DIN before being appointed (or within 28 days if they are the first director of a newly registered company).

ASIC Reporting and Annual Review Obligations

As a director, you are responsible for ensuring your company meets its obligations to ASIC. The most important annual obligation is the ASIC Annual Review.

The Annual Review

Each year, ASIC sends every registered company an annual review. This review:

• Confirms the company's registered details (address, directors, shareholders, share structure)
• Includes a solvency resolution requirement
• Includes the annual review fee invoice

What you must do:

1. Pay the annual review fee — within 2 months of the review date
2. Pass a solvency resolution — the directors must resolve whether the company can pay its debts as and when they fall due
3. Update any incorrect details — if the information in the review is wrong, you must notify ASIC within 28 days

Missing the annual review fee results in late fees starting at $91 for the first month and increasing significantly thereafter. Failing to update incorrect details is an offence.

Notifying ASIC of Changes

You must notify ASIC within prescribed timeframes when:

• Director or secretary details change — within 28 days (name, address, date appointed, date ceased)
• Registered office address changes — within 28 days
• Principal place of business changes — within 28 days
• Shareholder details change — within 28 days of a share transfer
• Constitution changes — within 14 days

Use ASIC's online portal (ASIC Connect) to lodge these notifications. Failure to notify is an offence, and persistent failure can result in enforcement action.

Solvency and Financial Record-Keeping

Directors of small companies are not required to lodge audited financial statements with ASIC unless the company is a "large proprietary company" (defined by thresholds around consolidated revenue, assets, and employees). Most SMBs fall well below these thresholds.

However, you are still required to:

• Keep financial records that correctly record and explain the company's transactions and financial position (section 286)
• Retain those records for at least 7 years
• Be able to produce them to ASIC on request

The solvency resolution you pass each year is a legal declaration. Passing a resolution that the company is solvent when you know (or ought to know) it is not creates serious personal exposure.

Common Mistakes Small Business Owner-Directors Make

Not Treating the Company as a Separate Entity

The most pervasive mistake is treating company money as personal money. Paying personal expenses directly from the company account, lending money to yourself informally, or failing to maintain proper loan accounts all create problems — with the ATO (Division 7A) and with creditors if the company ever becomes insolvent.

Ignoring ASIC Notifications

ASIC sends annual review notices and follow-up reminders by mail and email. These get lost in the shuffle of running a business. Ignoring them leads to late fees, deregistration risk, and potential offences.

Missing Director Appointments and Resignations

When a co-director joins or leaves, many small businesses fail to notify ASIC within the required 28-day window. This is a straightforward compliance obligation that often gets forgotten.

Not Having a DIN

Despite the requirement being in place since 2022, some directors have not yet obtained their DIN. This exposes them to civil penalties.

Leaving Everything to the Accountant

Your accountant can prepare your financials and lodge your ASIC fees — but the legal obligations are yours. You cannot delegate director duties. If your accountant misses an ASIC deadline or fails to tell you about a solvency issue, you are still personally responsible.

Continuing to Trade While Insolvent

The most costly mistake. Directors who allow companies to keep incurring debts when the company cannot pay them face personal liability for those debts. The pressure to "keep going" and hope the situation improves is understandable — but it compounds the problem and the liability.

Penalties for Breaching Director Duties

The consequences of breaching director duties range from serious to catastrophic:

| Breach | Civil penalty | Criminal penalty | |--------|--------------|-----------------| | Failure of care and diligence (s180) | Up to $1.565M | N/A (civil only) | | Breach of good faith (s181) | Up to $1.565M | Up to 5 years imprisonment | | Improper use of position (s182) | Up to $1.565M | Up to 5 years imprisonment | | Improper use of information (s183) | Up to $1.565M | Up to 5 years imprisonment | | Insolvent trading (s588G) | Compensation order for company's loss | Up to 5 years imprisonment (dishonest) | | Failure to obtain DIN | Up to $13,320 | Up to 12 months imprisonment |

ASIC also has the power to disqualify you from managing a corporation — effectively preventing you from being a director — for serious breaches.
