Am I personally liable for company debt in Australia?
For most directors, most of the time, the answer is no: the whole point of a company is that its debts are its own. But there are well-defined exceptions, and they tend to be exactly the ones that matter when a business is under strain. This is a plain-English guide to the general rule of limited liability and the main situations where company debt can become your personal problem.

The general rule: limited liability
A company is a separate legal person from the people who own and run it. That is not a technicality; it is the foundation of how business is done. It means that when the company borrows, buys stock, or signs a lease, those obligations belong to the company, and if the company cannot pay them, creditors generally look to the company's assets, not to the director's house or savings. This is what limited liability means, and it is why people incorporate in the first place: so that an honest business failure does not also become a personal financial ruin. The exceptions below are real and worth knowing, but they are exceptions to this rule, not a sign that the rule is weak.
Exception one: personal guarantees
The most common way directors become personally liable is the most voluntary one: they signed for it. Banks, landlords, equipment financiers, and large suppliers frequently ask a director to give a personal guarantee before they extend credit to a smaller company. A guarantee is a promise that if the company does not pay, you will. It is easy to sign one in the optimism of a new venture and forget it exists until the company is in trouble, at which point the guarantee quietly converts a company debt into a personal one. The practical lesson is to know which of your obligations are personally guaranteed before you need to, because those are the debts that follow you even if the company is wound up.
Exception two: director penalty notices
For certain tax debts, the ATO can reach a director directly through a director penalty notice. These notices can make a director personally liable for the company's unpaid PAYG withholding, GST, and super guarantee charge. If the company has lodged its returns on time, a notice usually gives you a window to respond, for instance by paying the amount or placing the company into administration or liquidation. If those amounts were never reported at all, the notice can be a lockdown notice, where the liability is automatic and cannot be shed by entering a formal process. This is why lodging on time matters even when you cannot pay: lodging is what keeps your options open.
Exception three: insolvent trading
The third major exception arises from how the company is run rather than from anything you signed. If a director allows the company to incur new debts when it is insolvent, or where the new debt tips it into insolvency, they can be made personally liable for those debts. This is the duty against insolvent trading, and it is one of the most important reasons to take cash-flow trouble seriously rather than trading on in hope. Our companion article on whether your company is trading while insolvent explains the cash-flow and balance-sheet tests in more detail, along with the protections available to directors who act in good faith.
How to keep the line between company and personal
The thread running through every exception is timing. Personal guarantees bite when the company defaults; director penalty notices bite when reporting and payment have slipped; insolvent trading bites when a director keeps incurring debts a struggling company cannot meet. In each case, the protection is the same: keep your lodgements current, know which debts you have personally guaranteed, and act early if the company's ability to pay its bills starts to wobble. The earlier you see a problem, the more of the company-versus-personal line you can keep intact. If you are at the point where any of this feels close to home, that is the moment to get advice rather than wait. This is general information, not legal advice.
