Director Personal Liability Under the Corporations Act in Australia

If you run a company in Australia, you’ve probably heard the phrase “limited liability” and felt a bit reassured. In many situations, it’s true: a company is a separate legal entity, and the company’s debts aren’t automatically your personal debts.

But here’s the part many founders and SME owners don’t hear early enough: directors can still face very real personal liability under Australia’s “companies act” rules (which is usually shorthand for the Corporations Act 2001 (Cth) and related laws).

This matters because most directors of small businesses and startups aren’t “career directors” - you’re often the founder, the operator, the sales lead, and the person approving payments. That hands-on role is great for execution, but it can also mean you’re closer to the decisions that create director liability.

Below, we’ll walk you through what personal liability can look like for directors, the common risk areas we see in SMEs and startups, and practical steps you can take to reduce your exposure while still moving fast.

Why Can Directors Be Personally Liable If The Company Has “Limited Liability”?

“Limited liability” usually means shareholders are not personally responsible for company debts just because they own shares.

Directors are different. A director has legal duties and responsibilities attached to their role. If those duties aren’t met, the law can “look past” the company and hold the director personally responsible.

For Australian SMEs, personal liability risks often arise because:

• directors make (or approve) financial decisions day-to-day
• companies run lean and don’t always have strong governance early on
• cashflow pressure can lead to “keep trading and hope it works out” decisions
• founders mix personal and business dealings (sometimes without realising the legal consequences)

The key point is this: being a director is not just a title for your LinkedIn profile - it’s a legal role with obligations, and those obligations can lead to personal exposure if something goes wrong.

What Are The Key Personal Liabilities Of Directors Under Companies Act Rules?

When people search for the “personal liabilities of directors under companies act” rules, they’re usually trying to understand what could realistically happen if the company hits trouble.

Below are the most common director liability areas under the Corporations Act and related regimes that affect SMEs and startups.

1. Breach Of Director Duties (Care, Diligence, Good Faith, Proper Purpose)

Directors generally need to:

• act with care and diligence
• act in good faith in the best interests of the company
• act for a proper purpose
• avoid conflicts of interest and improper use of position/information

In practical terms, this can show up in situations like:

• approving major spend without understanding the numbers
• not reading (or questioning) financial reports
• using company opportunities for personal benefit
• making decisions that benefit one shareholder/founder at the expense of the company

These duties can lead to civil penalties, compensation orders, and in some cases criminal consequences (particularly where dishonesty is involved).

2. Insolvent Trading

Insolvent trading is one of the most well-known areas where directors can be personally liable.

Broadly, directors have a duty to prevent the company from incurring debts when the company is insolvent, or where incurring that debt would make the company insolvent.

This is where a lot of well-meaning SME directors get caught. It can happen when you:

• keep placing orders with suppliers while overdue debts are stacking up
• continue to employ staff when payroll can’t realistically be met
• sign new leases or service contracts “to buy time”
• raise money on optimistic assumptions without a clear path to solvency

There are defences and “safe harbour” style protections in some circumstances, but they typically depend on you taking active, documented steps to develop a course of action reasonably likely to lead to a better outcome than immediate insolvency administration.

3. ATO Director Penalty Notices (PAYG Withholding And Superannuation)

For many SMEs, one of the most practical personal liability risks doesn’t come from a customer or supplier - it comes from the ATO.

In certain circumstances, the ATO can issue a Director Penalty Notice (DPN) that can make directors personally liable for unpaid PAYG withholding and superannuation guarantee (and related amounts), particularly where obligations aren’t reported and addressed in time.

If your business is falling behind on BAS, PAYG, or super, it’s important to get advice early. This is an area where timing, reporting, and the steps you take can significantly affect director exposure.

4. Unfair Preferences And “Last-Minute” Payments (Indirect Exposure)

While unfair preference claims are often pursued against creditors who received payments (not always directly against directors), directors of SMEs should still treat this area seriously because last-minute payment decisions can:

• increase overall insolvency risk
• trigger disputes with liquidators later
• create allegations about director conduct and decision-making

If you’re facing cashflow stress, it’s worth getting advice early before you start “triaging” creditor payments informally.

5. Misuse Of Position Or Information

Directors can’t use their position (or information gained as a director) improperly to gain an advantage for themselves or someone else, or to cause detriment to the company.

For startups, this can show up in founder break-ups or restructures where:

• one director diverts customers to a new entity
• company IP is transferred out without proper approvals
• confidential pricing or roadmap data is used to compete

Even if you believe you’re acting fairly, the legal test isn’t “what you meant” - it’s whether the use was improper and caused disadvantage.

6. Defective Governance Documents (The Hidden Liability Amplifier)

While the Corporations Act sets the baseline rules, your internal governance documents can either reduce risk or create more uncertainty.

For example, a well-drafted Company Constitution can clarify how decisions are made, which approvals are required, and what happens when founders disagree.

And if you have multiple shareholders (common in startups with co-founders and early investors), a Shareholders Agreement can reduce the odds that a commercial disagreement turns into allegations of director misconduct.

What Director Liability Risks Are Most Common For SMEs And Startups?

In our experience, the biggest problems aren’t usually caused by “bad people doing bad things.” They’re caused by fast growth, poor documentation, and cashflow pressure.

Here are a few patterns that come up a lot in small businesses and startups.

Founder Spending And Informal Approvals

Early-stage businesses often run on trust. Purchases get approved in Slack, email, or verbally.

The issue is that if the business later fails, those informal approvals can look like a lack of care and diligence - especially if the spending wasn’t justified by budgets, forecasts, or board consideration.

A simple habit change helps: record major decisions in short written resolutions and store them centrally.

Mixing Personal And Company Money (Including “Borrowing” From The Company)

Many SME owners treat the company bank account like an extension of personal finances, especially in the early days.

This can create tax issues, governance issues, and disputes with co-founders or investors. It can also become a director liability issue if the company becomes insolvent and transactions are scrutinised.

If you’ve ever taken money out of the business “temporarily” or paid personal expenses through the company, you should understand how a director loan works and how it should be documented.

Signing Contracts Without Proper Authority Or Process

Many directors sign customer and supplier contracts quickly to keep revenue moving.

But poor signing processes can create disputes about whether the contract is binding, whether it was properly authorised, and whether the director made representations outside the contract terms.

It’s worth setting a clear internal signing policy, particularly around signing documents under section 127 (and what you’ll do when there’s only one director, or when you use electronic signing tools).

Cashflow Stress And “Just Keep Trading” Decisions

When your runway gets short, it’s easy to slip into reactive decisions:

• taking on new work that you can’t deliver profitably
• agreeing to harsh payment terms
• delaying tax or super payments to cover urgent supplier invoices

These can all increase insolvent trading risk and other personal exposure issues. Even if the business survives, this period often creates the paperwork problems that cause future disputes.

Grant Funding, Equipment Finance, And Security Interests

SMEs and startups often take equipment finance, vendor finance, or other funding arrangements that involve security interests.

If you’re giving security over business assets (or taking security from customers), you’ll want to understand how to register a security interest and what can go wrong if registrations aren’t handled properly.

This isn’t always “director personal liability” in the strictest sense, but when a finance arrangement unravels, directors are often the ones dealing with the fallout - including personal guarantees (which are separate to the Corporations Act, but common in SME lending).

How Can You Reduce Personal Liability As A Director (Without Slowing The Business Down)?

Director liability isn’t something you “solve” once. It’s something you manage with good habits, good documents, and good decision-making processes.

Here are practical steps that help most SMEs and startups.

1. Know Your Numbers (And Document That You Know Them)

You don’t need to be an accountant - but you do need to understand the company’s financial position enough to make informed decisions.

Simple actions that help:

• review management accounts regularly (even monthly)
• ask for a cashflow forecast (and update it when assumptions change)
• track aged payables and receivables
• record key decisions: what you considered, what information you relied on, and why you chose that path

This isn’t just “admin”. If your decisions are later questioned, a paper trail can be critical.

2. Hold Short, Regular Board Meetings (Even If It’s Just Founders)

Many SMEs don’t treat themselves like “real companies” until something goes wrong.

But good governance doesn’t have to be formal or time-consuming. A 30-minute monthly meeting with a short agenda and notes can go a long way.

For example, you might cover:

• financial position and cashflow
• key contracts signed this month
• staffing and payroll changes
• any disputes or customer complaints
• upcoming funding or major purchases

3. Get Your Founder And Ownership Documents Right Early

Startups move quickly, and it’s common to “sort the legal later”. But unclear ownership and decision-making structures often lead to personal risk for directors - especially when relationships break down.

Clear governance documents, like a constitution and shareholders agreement, help you show that decisions were made properly and that everyone understood the rules.

4. Use Contracts To Control Risk (Especially Around Payment And Scope)

One of the fastest ways SMEs end up in trouble is when projects run over budget, customers dispute invoices, or a supplier relationship collapses.

Well-drafted contracts help set expectations and reduce the chances that a commercial dispute becomes a legal dispute that drains cashflow (which then increases director liability risk).

If you have staff, proper documentation matters here too - including having an appropriate Employment Contract in place so roles, responsibilities and termination processes are clear.

5. Treat Insolvency Risk Like A “Red Flag”, Not A Motivation Tool

Some founders treat “pressure” as a performance strategy. But insolvency risk is a legal issue, not just a business issue.

If you see warning signs like repeated late payments, ATO pressure, missed superannuation, or constantly renegotiated supplier terms, it’s worth pausing and getting advice on options.

Often, early advice gives you more choices - renegotiation, restructuring, refinancing, or changes to the operating model - before the business reaches a point where directors are exposed.

When Should You Get Legal Advice About Director Liability?

You don’t need a lawyer for every decision. But director liability risk tends to spike in a few key moments.

Consider getting advice if you’re facing any of the following:

• Cashflow stress: you’re behind on tax, super, payroll, or supplier invoices
• Founder conflict: co-founders disagree on spending, strategy, or control
• Raising capital: you’re bringing in investors and issuing shares
• Signing major contracts: leases, distribution deals, high-value customer agreements, or finance arrangements
• Restructuring: transferring assets, changing entities, or winding down part of the business

These are the moments where documenting decisions properly, ensuring authority to sign, and understanding director duties can make a major difference later.

Because director liability can overlap with tax and insolvency issues, you may also need advice from a registered tax agent/accountant and, where relevant, a registered liquidator or insolvency practitioner.

Key Takeaways

• “Limited liability” doesn’t mean directors are risk-free - personal liabilities of directors under “companies act” rules (mainly the Corporations Act and related regimes) can apply in several common SME scenarios.
• Director duties (care and diligence, good faith, proper purpose, and avoiding misuse of position/information) can create personal exposure if decision-making is careless or conflicts aren’t managed.
• Insolvent trading is a major risk area for startups and SMEs, especially during cashflow crunches when businesses keep trading and taking on new debts.
• For many SMEs, ATO enforcement (including Director Penalty Notices for PAYG withholding and superannuation) is a common pathway to personal director exposure if reporting and payments fall behind.
• Strong governance documents and clean signing processes help reduce disputes and show decisions were made properly.
• Good habits (financial oversight, short board meetings, written records, and clear contracts) can reduce personal exposure without slowing down the business.
